Description

The present invention relates to a lime spreader used to spread lime on passages leading to chicken houses, pig pens, etc.

In poultry farms, pig farms, etc., it is necessary to spray lime on passageways leading to chicken houses, pig pens, etc. for epidemic prevention purposes such as countermeasures against highly pathogenic avian influenza.

However, conventional lime spreaders were developed for the purpose of spreading lime on farms, and the lime is stored in a case attached to a tractor, and an opening is provided in the case, and the opening is opened and closed by an opening and closing body. (For example, see Patent Document 1).

Japanese Patent Application Publication No. 2-123819

Since the above-mentioned conventional lime spreader is used for agricultural purposes, problems may occur if it is used as is for epidemic prevention purposes in poultry farms, pig farms, etc.

For example, conventional lime spreaders are configured to allow lime to fall naturally from the opening of the case and spread, so the amount of lime spread may be too small for epidemic prevention in poultry farms, pig farms, etc.

In addition, it is necessary to switch whether or not lime is to be sprinkled by opening and closing the opening/closing body, which may increase the burden on the operator.

Therefore, in the present invention according to claim 1, in the lime spreading machine, a traction tool and wheels are provided in the lime storage case that stores lime, and a lime discharge mechanism for spreading lime is provided in the lower part of the lime storage case. The rotation shaft of the wheel and the drive shaft of the lime discharge mechanism are interlocked and connected via a ratchet mechanism, and when the wheel is towed in the forward direction, the drive shaft rotates together with the rotation shaft of the wheel, and lime is scattered from the lime discharge mechanism. The front side is configured so that lime is not scattered from the lime discharge mechanism due to rotation of the rotating shaft of the wheel when towed in the reverse direction, the towing tool is horizontally extended, and the lime storage case is stopped with the towing tool in a horizontal state. It was decided to provide a stopper and a rear stopper that stops the lime storage case in a state where the traction tool is tilted upward from the horizontal .

Further, in the present invention according to claim 2 , in the present invention according to claim 1 , in a state where the traction tool is tilted upward from horizontal, The lime was made to slide down along the line toward the lime discharge mechanism.

Further, the present invention provides the effects described below.

That is, in the lime spreading machine of the present invention, a traction tool and wheels are provided in a lime storage case that stores lime, and a lime discharge mechanism for spreading lime is provided in the lower part of the lime storage case, and the rotation axis of the wheel is and the drive shaft of the lime discharge mechanism are interlocked and connected via a ratchet mechanism, and when the vehicle is towed in the forward direction, the drive shaft rotates together with the rotating shaft of the wheel, and lime is scattered from the lime discharge mechanism, and the vehicle is towed in the reverse direction. Because the structure is designed to prevent lime from being sprayed from the lime discharge mechanism due to the wheel's rotating shaft spinning at times, a predetermined amount of lime is forcibly sprayed from the lime discharge mechanism only when the lime spreader is moved forward. Therefore, the amount of lime required for epidemic prevention in poultry farms, pig farms, etc. can be easily sprayed, and it can be used for epidemic prevention purposes in poultry farms, pig farms, etc.

In particular, a front stopper that extends the traction tool horizontally and stops the lime storage case when the traction tool is horizontal, and a rear stopper that stops the lime storage case when the traction tool is tilted upward from the horizontal. If provided, it is possible to prevent the lime spreader from tipping forward or backward, and to maintain the lime storage case at an appropriate inclination within the range regulated by the front stopper and rear stopper. Appropriate amount of lime can be sprinkled.

In addition, if the traction tool is tilted upwards from the horizontal and the lime is allowed to slide down toward the lime discharge mechanism along the walls immediately before and after the lime discharge mechanism, the lime When the spreader is moved forward to spread lime, the lime can be well collected inside the lime storage case toward the lime discharge mechanism, and a predetermined amount of lime can always be spread.

Enlarged view of the same parts (ratchet mechanism (a), lime discharge mechanism (b)). The side view which shows the lime spreader at the time of lime spreading. Enlarged view of the same part.

EMBODIMENT OF THE INVENTION Below, the concrete structure of the lime spreader based on this invention is demonstrated with reference to drawings.

As shown in FIGS. 1 to 4, the lime spreader 1 has a traction tool 3 attached to the top of a lime storage case 2, and wheels 4, 4 rotatably attached to the left and right lower portions of the lime storage case 2.

The lime storage case 2 has a hollow box-like shape with an upper opening and an inclined bottom wall 9 with a high front and a low rear at the bottom of vertical vertical walls 5, 6 and left and right side walls 7, 8. , the lime that is introduced through the upper opening is stored inside.

A traction tool 3, which extends horizontally from front to back and has a U-shape in plan view, is installed across the upper portions of the left and right side walls 7, 8 of the lime storage case 2.

Further, rotating shafts 10, 10 of wheels 4, 4 are rotatably supported in the middle portions of the left and right side walls 7, 8 of the lime storage case 2. A U-shaped guard frame 11 is provided straddling the outer ends of the left and right rotating shafts 10, 10.

Furthermore, a lime discharge mechanism 12 for forcibly discharging (spreading) lime is provided at the inner lower end of the lime storage case 2.

The lime discharge mechanism 12 is rotatably attached to a drive shaft 13 extending horizontally between the lower ends of the left and right side walls 7 and 8 of the lime storage case 2, and protrudes in the radial direction from the outer peripheral surface of the drive shaft 13. A plurality of brushes 14 are installed at equal intervals laterally and circumferentially.

In addition, the lime discharge mechanism 12 covers the base plate 15 in an opening formed at the lower end of the lime storage case 2 (a portion surrounded by the front and rear walls 5, 6, left and right side walls 7, 8, and the lower end of the bottom wall 9). It is set up. The base plate 15 is recessed in an arc shape from side to side along the drive shaft 13, and the tip of the brush 14 that rotates together with the drive shaft 13 comes into contact with the inner surface. In this base plate 15, a plurality of elongated discharge ports 16 extending left and right are formed in a staggered manner at alternating intervals in the front and rear and left and right directions.

In the lime discharge mechanism 12, when the drive shaft 13 is rotated, the brush 14 rotates accordingly, and the lime contained in the lime storage case 2 is forcibly directed downward from the discharge port 16 by the brush 14. It is designed to be discharged. Note that the lime discharge mechanism 12 can discharge a predetermined amount of lime according to the rotational speed of the drive shaft 13 (wheels 4) (the forward speed of the lime spreader 1). In addition, the lime discharge mechanism 12 has a horizontally long rectangular cylindrical cover 17 attached downward around the base plate 15 to prevent the lime discharged from the discharge port 16 from scattering.

In this lime discharge mechanism 12, the left end of a drive shaft 13 is interlocked and connected to the rotating shaft 10 of the left wheel 4 when viewed from the front via a ratchet mechanism 18. That is, in the lime spreader 1, the drive gear 19 is attached to the rotating shaft 10 of the wheel 4 via the ratchet mechanism 18 configured to transmit power only when the rotating shaft 10 rotates forward (when the wheel 4 moves forward). A driven gear 20 is attached to the drive shaft 13 of the discharge mechanism 12, and the drive gear 19 and the driven gear 20 are connected by a chain 21.

Thereby, the lime discharge mechanism 12 discharges lime only when the wheel 4 moves forward, with power being transmitted from the rotating shaft 10 of the wheel 4 to the drive shaft 13 via the ratchet mechanism 18.

In addition, the lime spreader 1 is equipped with a pair of left and right front stoppers 22, 22 vertically adjustable at the lower front side of the bottom wall 9 of the lime storage case 2, and left and right at the lower rear side of the rear wall 6 of the lime storage case 2. A pair of rear stoppers 23, 23 are attached so as to be adjustable up and down.

The front stoppers 22, 22 are designed to come into contact with the ground when the towing tool 3 is in a horizontal state and the front and rear walls 5, 6 and left and right side walls 7, 8 of the lime storage case 2 are vertical. It is designed to stop the storage case 2 from moving toward the front (overturning). On the other hand, the rear stoppers 23, 23 are designed to contact the ground with the traction tool 3 tilted upward from the horizontal, thereby preventing the lime storage case 2 from moving rearward (overturning). It is designed to stop.

Then, the lime spreader 1 is stopped with the towing tool 3 in a horizontal state (the front and rear walls 5, 6 and the left and right side walls 7, 8 of the lime storage case 2 are vertical) using the front stoppers 22, 22. be able to.

In addition, when the operator enters inside the towing tool 3 from a stopped state and lifts the towing tool 3 upward, the lime spreader 1 can be moved between the front stoppers 22, 22 and the rear stopper, as shown in FIGS. 5 and 6. 23, 23 are away from the ground (a predetermined angular range), the lime storage case 2 is tilted rearward, and the bottom wall 9 of the lime storage case 2 is tilted forward toward the lime discharge mechanism 12. The rear wall 6 is inclined in a low front and rearward direction toward the lime discharge mechanism 12, and the lime stored inside the lime storage case 2 is tilted toward the lime discharge mechanism 12 on the front wall (bottom). It continues and smoothly slides down toward the lime discharge mechanism 12 along the wall 9) and the wall immediately behind (rear wall 6).

After that, when the lime spreader 1 is moved forward using the traction tool 3, power is transmitted from the rotating shaft 10 of the wheel 4 to the drive shaft 13 of the lime discharge mechanism 12, and lime is forcibly discharged from the lime discharge mechanism 12 ( can be dispersed). On the other hand, when the lime spreader 1 is moved backwards, the ratchet mechanism 18 prevents the transmission of power from the rotating shaft 10 of the wheel 4 to the drive shaft 13 of the lime discharge mechanism 12, causing the rotating shaft 10 of the wheel 4 to idle. Then, the drive shaft 13 of the lime discharge mechanism 12 stops, and lime is no longer discharged (sprayed) from the lime discharge mechanism 12.

As explained above, the lime spreading machine 1 includes a lime storage case 2 that stores lime, a traction tool 3 and wheels 4, and a lime discharge mechanism for spreading lime at the lower part of the lime storage case 2. 12 is provided, and the rotation shaft 10 of the wheel 4 and the drive shaft 13 of the lime discharge mechanism 12 are interlocked and connected via a ratchet mechanism 18, so that the drive shaft 13 rotates together with the rotation shaft 10 of the wheel 4 when the wheel is towed in the forward direction. Lime is sprayed from the lime discharge mechanism 12, and when the vehicle is towed in the reverse direction, the rotating shaft 10 of the wheel 4 idles and lime is not sprayed from the lime discharge mechanism 12.

Therefore, in the lime spreader 1 having the above configuration, a predetermined amount of lime can be forcibly spread from the lime discharge mechanism 12 only when the lime spreader 1 is moved forward, so it is possible to forcibly spread a predetermined amount of lime from the lime discharging mechanism 12. The required amount of lime can be easily spread, and it can be used for epidemic prevention purposes in poultry farms, pig farms, etc.

The lime spreader 1 also includes front stoppers 22, 22 that extend the traction tool 3 horizontally and stop the lime storage case 2 with the traction tool 3 in a horizontal state, and a front stopper 22, 22 that allows the traction tool 3 to be tilted upward from the horizontal position. The structure includes rear stoppers 23, 23 for stopping the lime storage case 2 in this state.

Therefore, in the lime spreader 1 having the above configuration, it is possible to prevent the lime spreader 1 from falling forward or backward, and to accommodate lime within the range regulated by the front stoppers 22, 22 and the rear stoppers 23, 23. An appropriate amount of lime can be spread by keeping the case 2 in an appropriately inclined state.

Furthermore, the lime spreader 1 is configured to operate along the walls (bottom wall 9 and rear wall 6) on the front and rear sides of the lime discharge mechanism 12 with the towing tool 3 tilted upward from the horizontal. The structure is such that lime slides down toward the lime discharge mechanism 12.

Therefore, in the lime spreader 1 having the above configuration, when the lime spreader 1 is moved forward to spread lime, lime can be well collected inside the lime storage case 2 toward the lime discharge mechanism 12, and a predetermined amount can always be collected. can be sprinkled with lime.
