Description

[0001]
[Industrial application fields]
The present invention relates to the handling of rice husks that are generated in large quantities during rice hulling operations such as rice farming, and a rice husk spraying device that is limited in size so that it can be carried using the hydraulic mechanism of an agricultural tractor is provided in advance. Single or multiple units are placed side by side, and then the cereals discharged from the hulling machine are blown in order from the dust tube insertion port, and when the cereals are full, they are lifted and lifted by the lifter set on the tractor. In addition, the present invention is to provide a rice husk spraying device that opens a shutter at a predetermined place and sprays rice husk on a field or the like.
[0002]
[Prior art]
At the end of the rice harvesting operation, there is a rice hulling operation, and at this time the amount of rice kernels equivalent to about half of the rice hulls is released from the duster of the rice huller, and this dusty and scratching rice husk is processed for the farmers. Has been forced to work hard.
[0003]
For processing rice husks, the piles of rice husks are set to fire to make charcoal, or burned completely, or the rice husk collector is connected to a rice huller to pack the rice husks, and then trucks, etc. It is carried on the bag and sprinkled with rice husks.When spraying, open the bag mouth, then with the mouth down, pull back over the bag by hand, It's a time-consuming and troublesome task.
[0004]
Therefore, a truck or trailer is framed, and the grains are discharged and packed directly from the rice huller. After the rice hulling work is completed, it is transported to a predetermined place and the loaded rice hulls are sprayed. There are also means, and this spraying is done by one person driving at a low speed and the other person getting on the carrier and dropping with a scoop etc. Not only is it hard to do it, but it is not only a very hard work, but also dust rises in the frame, which can be a dusty work that can damage the trachea.
Although the movement of rice husk packed in bags due to the spread of rice husk collectors has been freed from the heavy labor of loading on trucks etc. with the above-mentioned scoop etc., the above-mentioned difficulties have still been resolved in terms of spraying. Not.
[0005]
However, the problems that occur when this trailer is used cannot be solved by means such as providing a shutter that can be opened and closed at the bottom, and discharging it. Even though the harsh work has improved, it is very difficult to drive in the case of processing with a trailer, especially if the back does not have considerable experience, it can not be driven. It is not a good idea to simply turn the steering wheel in the reverse direction. When you are not accustomed to knowing the knack, it will meander to the right and left, and you will not be able to put it in as long as you want to put it in the garage. However, it is difficult to give up and give up, which is impossible for women and elderly people. In addition, the trailer itself is bulky and the trailer with a shutter mechanism is too expensive, and it is expected that it will be difficult to adopt depending on the farm size due to storage location and economic burden etc. Is done.
[0006]
Therefore, a rice husk spraying device that can discharge rice husks from the bottom or a container that can dump and discharge rice husks can be attached to the three-point link of the agricultural tractor hydraulic mechanism, but in that case, unless it is a fairly large container, Usually, it is difficult to transport the rice husks that come out in one hulling operation at a time, and the hulling operation cannot be performed unless the hulling operation is interrupted and the grain of the container is discarded. Even if you make such a thing, there is a risk that a container that is too large can not be lifted by the hydraulic mechanism, or even if you lift it, the front wheel of the tractor may float and fall over A sturdy support frame that supports the weight of the cereal grains and the entire container, and a rice husk sprayer equipped with a hitch for attachment to the tractor, etc. If the same container is used side by side, the economic burden on the farmers is considerable as in the case of using the trailer. It will be a thing.
[0007]
[Problems to be solved by the invention]
Therefore, in order to make a low-priced economical container, it is necessary to separate the container that contains the rice husks from the sturdy and expensive support frame that is a lump of iron. Install a forklift-like object, and easily insert nails into the center of the pallet (loading platform). The container will not slip even when traveling on uneven farm roads. There is a need.
In the present invention, as a result of continual development and research in order to cope with the conventional situation and solve the above-mentioned problems, the present invention succeeded in realizing a new rice husk spraying apparatus having a configuration as described in detail below. It is a thing.
[0008]
[Means for Solving the Problems]
As clearly understood from the embodiments representing the individual inventions shown in the drawings, the rice husk spraying apparatus of the present invention basically has the following configuration.
That is, hitch pins that are connected to the working machine attachment link of the agricultural tractor hydraulic mechanism are installed at the main points, and the support frame arranged upright and the rear side of the support frame from both sides of the support frame are horizontally and parallel to each other over a predetermined length. In contrast to a lifter formed by integrating a pair of substantially inverted V-shaped claws extending in the shape of a side surface into an L-shaped shape, a portion corresponding to the pair of claws of the lifter has a substantially inverted V-shaped cross section. A horizontally-long rectangular bottom plate that has a slightly larger cross-section receiving port and is set to be larger than the receiving space between the receiving ports, and is placed in a balanced manner on the left and right sides of the pair of receiving ports. The front and rear dimensions are formed by forming a rice husk storage space surrounded by a peripheral wall of a predetermined height above a horizontally-oriented flat loading platform with a built-in shutter that can be opened and closed. A rice husk spraying device with a gist of a structure in which a box-shaped container body having a horizontally long flat plane with a predetermined height and a predetermined height is inserted and combined into a receiving port so that the nail of the lifter can be inserted and removed freely. It is.
[0009]
In other words, a hitch pin that is connected to the work equipment mounting link of the agricultural tractor hydraulic mechanism is installed at the key points, and the support frame that is arranged upright, and a predetermined length rearward from both sides of the lower end of the support frame. With respect to a lifter formed by integrating a pair of substantially inverted V-shaped claws extending horizontally and parallel to each other into a side-shaped L-shape, the cross-sections of the claws are approximately at positions corresponding to the pair of claws of the lifter. A horizontally-long rectangular bottom plate having receptacles with a similar cross section slightly larger than the reverse V-shape, set above the receptacles and larger than the receptacle arrangement interval, and arranged on the pair of receptacles with a good left-right balance And a rice husk containing space surrounded by a peripheral wall of a predetermined height above a horizontally-oriented flat loading platform equipped with a horizontally movable shutter and a discharge opening that can be opened and closed. The box-shaped container body, which is a horizontally long planar shape with a larger left-right dimension than the front-rear dimension and has a predetermined height, is inserted into the receiving port so that the nail of the lifter can be inserted and removed freely. It can be said that the rice husk spraying device has a configuration in which the left and right shift movements are eliminated by the top.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
In implementing the present invention having the above-described configuration, the best or desirable mode will be described.
A lifter with two claws with a substantially inverted V-shaped cross-section formed in an L-shape integrally with a detachable support frame is formed on a work machine attachment link of an agricultural tractor, while the other box body At the bottom of the formed container body, there is a receiving port formed horizontally in a substantially inverted V shape for inserting a claw from the side, a discharge port for dropping cereals and a bottom plate at the top of the receiving port, and the discharge port Forms a cargo bed that combines shutters that can be freely opened and closed.
[0011]
It is a rice husk spraying system that uses a combination of lifter and container to provide a dust-cylinder insertion port for the introduction of rice husk at the appropriate location on the outer peripheral surface including the ceiling of the container body. In some cases, many containers are placed side by side. The rice husks discharged from the sliding machine are blown in, and on the other hand, the containers can be carried out one after another by lifters attached to the tractors, and the cereal grains can be sprayed by opening the shutters at predetermined places.
[0012]
When spraying cereals, this configuration, which pulls the shutter of the container body back manually, is the simplest and cheapest to provide, but if necessary, screws and reduction motors, sprockets and chains, handles The shutter may be mechanically slidable back and forth by operating or using the power of a hydraulic pump or the like connected to the battery so that it can be operated from the driver's seat. For that purpose, when the nail is inserted and connected to the receiving port of the loading platform, the connection point (core) between the shutter and the lifter must appear clearly.
Hereinafter, the embodiments taken up in the drawings will be described.
[0013]
[Example 1]
The first embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a lifter L connected to a three-point link (a one-touch hitch is also possible) of a tractor hydraulic mechanism.
In the lifter L, two bar-like claws L2 having a V-shaped cross section that is horizontally reversed toward the rear are arranged in parallel at the lower positions on both ends of the support frame L1 in which members such as iron pipes and flat irons are vertically arranged. The support frame L1 and the L-shaped integrated structure are formed. On the support tractor L1 front tractor side, a round bar-shaped hitch pin L4 for connecting a three-point link, like other well-known work machines, is located at two positions on the left and right sides of the substantially lower part of the support frame L1, and a substantially upper center position of the frame L1. It is assumed that a total of 1 location is provided.
[0014]
FIG. 2 is an overall perspective view of the other rice husk spraying device main body C with the shutter C4 closed. As can be understood from FIG. 8, the lifter L lifts and moves the shutter S, opens the shutter S and opens the grains. It can be sprayed.
[0015]
3 is a longitudinal sectional view of the nail insertion side of FIG. 3, a longitudinal sectional view of the state in which the shutter of FIG. 4 is closed, a longitudinal sectional view of the state in which the shutter of FIG. 5 is opened, a perspective view of the shutter of FIG. This will be described with reference to a perspective view of a loading platform portion of the container body and a partial longitudinal sectional view of the container body in FIG.
A loading platform C1 having a rectangular frame is formed in the lower part of the container, and a receiving port C2 having a substantially inverted V-shaped cross section and horizontally arranged so that the claw L2 can be inserted from the longitudinal direction of the loading platform C1 is provided in a shape larger than the claw L2. ing. The substantially reverse V-shape of the receptacle C2 may have any shape at the bottom as long as the apex has a substantially reverse V-shape. When the claw L2 is inserted into the receiving port C2 and lifted upward, the width is set so that the vertices of the substantially reverse V-shapes coincide with each other at two left and right positions.
[0016]
In addition, as can be understood from FIGS. 3, 4 and 5, a rectangular bottom plate C9 is attached to the center of the loading port C1 at the upper part of the receiving port C2 so as to block a part of the hole, and both sides are released in a rectangular shape. Discharge ports C3 and C3 are provided. The discharge port C3 can be closed and released by the horizontal movement of the shutter S in FIG. 6, and the shutter S is inserted from the shutter opening C13 on the opposite side to the receiving port C2, and is outside the rail C7 and the receiving port C2. It is placed on top.
[0017]
In the shutter S of FIG. 6, two shutter plates C4 and C4 are connected in parallel by a connecting rod C5. Although not shown, a hole is formed by cutting the center into a rectangle with one shutter plate. Even if it is opened, the same effect can be obtained, so it may be adopted.
In addition, although the number of outlets C3 of the loading platform C1 shown in the drawing is two, the number of those may be one or more, and of course, the shutter also corresponds to that of the outlets. Needless to say. The shutter C may be one that can be taken in and out from either the front-rear direction. Although not shown, it is also possible to overlap several shutters, fit each on several stages of rails, and draw them horizontally one by one from one side. If the shutter has a handle C6, it is convenient when opening and closing.
[0018]
The container main body C is framed by a column C10 of a pipe that rises on the upper part of the loading platform C1, and is composed of a peripheral wall C12 that is suspended by a hook C11 such as a string. A dust tube insertion port C8 is provided to allow insertion of the dust tube of the huller. The rice huller separates the rice cake into brown rice and rice husk, and the light pressure is applied to the container main body C by the wind from the rice huller because of the principle that the light rice grain length is sucked by the rice cake selection and blown out from the dust tube. If this happens, the suction balance will be lost, and the rice husk will be left behind by the hulling machine, which will adversely affect the sorting performance. For this reason, a part of the peripheral wall C7 including the ceiling or all of it must be made of a net-like material to escape the wind.
[0019]
However, although not shown in the figure, like the rice husk collector of Japanese Patent Publication No. 1-17742, the husk and wind are separated by a net with a slant inside the main body so that the husk falls downward and the wind is removed. If a device that can be discharged is placed on the ceiling, the material of the peripheral wall C7 may be a non-breathable sheet or plate. Further, it is convenient if the dust-cylinder insertion slot C8 adopts a fastener that can be opened and closed so as not to scatter during transportation. (The dust cylinder insertion port C8 in FIG. 2 shows a state closed with a fastener.)
It is desirable that the rice husk spraying device main body C of the present invention is formed so that each part of the peripheral wall C7 and the column C10 serving as a box can be easily disassembled and does not take up space for storage.
[0020]
【The invention's effect】
As described above, the rice husk spraying system and the rice husk spraying device of the present invention can easily set the lifter L to the tractor, and can insert the container body C containing the rice husk like a forklift. After plugging in, it is lifted with hydraulic pressure and transported to a predetermined place. When it arrives at a predetermined place, the hydraulic mechanism is lowered and the container is landed. Then you can spray rice husk.
[0021]
Further, since the lifter L and the container main body C are formed independently of each other, even if there is only one lifter L, if the number of containers is increased, continuous work can be performed without stopping the hulling work. The main body C is light and inexpensive, so the total cost can be reduced. In addition, it is freed from the heavy labor of spraying rice husks in bags as in the past, and in the frame of trucks and trailers. The effect that it becomes dusty and does not spread with a scoop is acquired.
[0022]
Furthermore, a mechanism that allows the rice husks to be sprayed on the trailer is also conceivable, but it is not only difficult to operate, but also requires an expensive and large storage space, so it is necessary to own such a thing. Furthermore, the shape of the apex of the claw L2 and the receiving port C2 is such that when the claw L2 is inserted and lifted up to a predetermined position, the cores (centers) come out because they are in close contact with each other in a reverse V shape and do not move. There is an advantage that it is convenient in terms of work.
[0023]
For example, the rice husk spraying system and the rice husk spraying device of the present invention, which manually opens and closes the shutter, can be provided with the simplest and cheapest, but if necessary, a screw and a reduction motor, a sprocket and a chain, a handle It is possible to open or close the shutter from the driver's seat mechanically by operating or using the power of a hydraulic pump connected to the battery. If necessary, the lifter L and the loading platform C1 are hooked together. Since fitting metal fittings can be attached, the container main body C can exhibit a feature that enables safe operation with less slippage and load collapse even when traveling on uneven farm roads.
