Description

[Detailed Description of the Invention] The present invention particularly relates to a rotary weeding and cultivating machine that is used while being guided by a tractor or the like, and its purpose is to weed between furrows and cultivate the roots of crops such as beans that are encased in the furrows. The purpose of the present invention is to enable the scraping to be carried out at once and simultaneously on a plurality of ridges using a plurality of horizontally rotating scraping members.

Another object of the present invention is to enable the plurality of horizontal rotary scraping sections to be individually moved up and down according to the unevenness of the ground. The goal is to always be able to do this accurately. The invention will now be described in detail with reference to the illustrated embodiments.

This rotary weeding soil cultivator has all its components mounted on a machine frame a which is made narrower by positioning the spreaders 2 and 2' between the left and right ends of the front and rear horizontal villages 1 and 1', which are long in the left and right directions. The structure is such that the frame a is connected to the rear side of a tractor (not shown) as will be described later, and while the tractor is traveling with a guide, power is extracted from the power output section of the tractor to automatically weed and cultivate soil.

That is, three pairs of rotary scraping bodies b and Q are installed in the machine frame a.
The set and separate rotary scraping bodies at the left and right ends located on the left and right sides of these are suspended and supported.

The pair of rotary scraping bodies b and b2 of each set maintain a required distance close enough to avoid contact with each other, and the rotary scraping bodies b and b2 of each pair and the left and right ends of the rotary scraping bodies b and These 3
Each rotary scraping body in the assembly and the wide rotary scraping body at both left and right ends, b3
are individually configured and similarly installed vertically on the machine frame a, and now one of them, the rotary scraper b
The configuration will be explained with reference to FIG.

The rotary scraper b has a plurality of vertical blade plates 6 radially fixed to the outer periphery of a horizontal disk 5 to the lower end of a vertical ball 4 rotatably supported on a vertical shaft tube 3. The horizontal rotary scraping member 7 is fixedly installed, and as the vertical shaft 4 rotates with respect to the barrel tube 3, the horizontal rotary scraping member 7 horizontally rotates. The rotary scraping body q is constructed by inserting the ball cylinder 3 vertically and slidably into the upper and lower guide cylinders 9 and 9' which are fixed to the hanging punch 8 installed vertically on the machine frame a. A cylindrical stopper 3' fixed to the guide tubes 9 and 9' is positioned between the guide tubes 9 and 9'.
In addition, a cylindrical stopper 3'' is fixed to the lower side of the medullary tube 3.
is located below the guide tube 9'. The rotary scraping body b can move up and down within the range where the stoppers 3', 3'' collide with the upper and lower sides of the guide cylinder 9', but normally, due to its own weight, the stopper 3' moves against the guide cylinder 9'. On the other hand, on the aircraft frame a side, the Fujimura 1
, 1', and a bearing sleeve gear 11 fixed to the lower side thereof, a bevel gear 12 and an outer cylinder 13 that rotates integrally with the bevel gear 12 are respectively supported.

The upper end of the vertical shaft 4 is inserted into the inner cylinder 14, which rotates integrally with the outer cylinder 13, so as to be able to move up and down.
A key 16 fixed to the inner peripheral surface of the bevel gear 12 is fitted so that the rotation of the bevel gear 12 is transmitted to the vertical shaft 4 via the outer cylinder 13 and the inner cylinder 14, and even during such rotation, the vertical axis 4 vertical movements are allowed. Next, the rotation transmission mechanism c for rotating the rotary scraping bodies all at once has a connecting shaft 17 attached to the lower side of the machine frame a for connecting to the force take-off section of the tractor, and a connecting shaft 17 attached to the upper side of the machine frame a. ,
1 connected to this connecting shaft 17 via a chain 18 etc.
A main transmission shaft 19 is constructed, and all the rotating scraping bodies rotate at the same time by having their respective bevel gears 12 meshed with a bevel gear 12' attached to the transmission shaft 19 by iron. Each pair of rotating scraping bodies b, b
2 are bevel gears 12' and 12' corresponding to each other.
Since the right and left sides are in opposite directions, they rotate outward from each other, as shown by the arrows in Figure 1, and similarly, the rotating members & and Q at both left and right ends rotate inward from each other. I'm starting to do that.

In addition, d and e are a pair of rotating scraping bodies, which are located before and after b2 and integrally with it, and d' and e' are leading parts which are located before and after the rotary scraping body and move up and down together with it. The blade and the support ring are attached to a mounting tube 21 provided at the front and rear of a mounting frame 20 fixed to a cylindrical stopper 3' fixed to the shaft tube 3 with iron fittings.
, 22, respective support punches 23, 24 are inserted in such a manner that their heights can be freely adjusted.

Further, the angle adjustment mechanism f provided for adjusting and setting the angle that the rotary scraping body makes with the ground is located at the front end of a pair of left and right fixed arms 25, 25' that project forward from the center of the machine frame a. , there are left and right connecting villages 27 whose lower ends are pivotally supported by shafts 26, 26'.
, 27' are connected and fixed to each other by a shaft 28, and to this shaft 28 is a U-shaped frame g, which has guiding holes 30, 30' fixed in parallel to the upper and lower sides of the connecting piece 29 facing rearward. It is rotatably mounted on the front end of the guide tube 30', and on the other hand, on the Fujimura 1 of the machine frame a, the rear end of the frame h, which has upper and lower guide tubes 31, 31', is rotatably mounted on the shaft 32. The guide holes 30, 30' are inserted into the guide tubes 31, 31', and the threaded end portion 33' of the handle 33, which is rotatably supported on the connecting piece 29 of the U-shaped frame g, is inserted into the frame h. The guide tube 31 is screwed onto a screw ring 34 provided on the lower side of the guide tube 31.

Therefore, when the connecting shaft 17 is connected to the force take-off part of the tractor, and the upper and lower ends of the connecting pestles 27, 27' are appropriately connected and fixed to the opposing parts of the tractor, the rotary weeding cultivator is run as a guide. , all the horizontal rotary scraping members 7 can be rotated and moved forward at the same time, and the blades 6 of each horizontal rotary scraper village can scrape grass between the ridges. It is possible to splash the grass together with the scraped grass and cover the roots of the crops in the rows, and weeding and cultivating many rows can be done at once.

In addition, the guide tube 3 that supports the vertical shaft 4 is connected to the guide tube 9.
, 9', each horizontal rotary scraping member 7 can move up and down individually and freely according to the unevenness of the ground, so that the above-mentioned weeding and soil removal can be carried out on the unevenness of the ground. No matter what, you can always do it accurately. Furthermore, when the handle 33 is rotated, the screw 34 advances or retreats along the tip threaded portion 33', and the frame h changes to the U-shaped frame g.
The machine frame a is moved back and forth between the connecting punches 27 and 2.
It rotates around the shafts 26 and 26' at the lower end of 7' as a fulcrum, that is, it rotates forward up or down, and the angles of all rotating scraping bodies b, , Q, and Q relative to the ground can be arbitrarily adjusted. The cutting depth of grass roots and the amount of fertilizer can be freely changed depending on the crop, type of grass, and growth rate.

In summary, the rotary weeding tower machine of the present invention has guide tubes superimposed on the left and right sides of a long machine frame, and a shaft tube is inserted into each guide tube so as to be able to slide vertically, and each shaft tube is perpendicular to the shaft tube. The shaft is rotatably penetratingly supported, and a horizontal rotating member, in which a plurality of blades are fixed radially to a horizontal disc, is fixed at the lower end of each vertical shaft, and a tractor, etc. is mounted on the machine frame. A connecting shaft for connecting to the force take-out part of the is attached, and a transmission shaft is constructed, and these connecting shafts and the transmission shaft are linked via a chain, etc., and this transmission shaft and each of the above-mentioned vertical shafts are connected. A bevel gear bonded to the former and a bevel gear connected to the upper end of the latter are linked by meshing with each other, and a support ring that runs on the ground is attached to the guide tube to rotate the connecting shaft. This makes it possible to horizontally rotate multiple horizontally rotating scraping members simultaneously, and by vertically sliding the ball tube along the guide tube, the multiple horizontally rotating scraping members can be individually and freely moved up and down. It has the following effects. {i} If the connecting shaft is connected to the power take-off part of a tractor or the like and the tractor is towed by it, multiple horizontally rotating scraping members can be rotated in unison and moved forward at the same time. The grass between the rows can be scraped off using the slats, and the grass can be thrown off along with the weeds and covered over the base of the crops in the rows, making it possible to remove weeds from many rows. and cultivating soil can be done all at once.

'o} The vertical shaft of the horizontally rotating scraping member is supported on the shaft cylinder, and the vertical shaft is inserted into the guide cylinder suspended from the machine frame so that it can move up and down, so each rotating scraping member can be placed on the ground. It can be moved up and down individually and freely according to the unevenness of the ground, and the above-mentioned weeding and cultivating can always be performed accurately even if the ground is uneven.

(1) Since the bearing wheel that runs on the ground is attached to the guide tube, there is no need to separately provide the machine frame with a dedicated support member for supporting the bearing wheel, and the structure can be simplified accordingly.
