Description

[Detailed description of the invention] [Industrial application field] The present invention connects the hitch part to a towing vehicle that does not have a lift arm that moves it up and down, and receives power from the towing vehicle to drive the working part. This article relates to a towed type mania spreader.

[Prior art and its problems] Conventional mania spreaders of this type
As shown in Fig. 7, a compost box 2 is mounted on a towed vehicle body 1, and a floor conveyor 3 for transporting the loaded compost is installed on the floor of the compost box 2. box 2
A beater 4 is installed in the open opening opened at the rear of the composter to spread the compost that is sent later.
Moreover, the floor conveyor 3 and the beater 4 can rotate only in the normal direction. Moreover, the vehicle body 1 has an open opening at the rear end of the compost box 2 mounted thereon.
It is configured to be held at a constant height higher than the field.

Then, compost is loaded into the compost box 2 manually, by another tractor equipped with a front loader, by a compost blower, etc., and the compost is loaded onto the floor conveyor 3.
By driving the beater 4 with power from the tractor, the compost is used to spread the compost over the field.

However, loading compost manually is not efficient, and preparing a dedicated compost loading machine is
It is not economically viable for a typical farm size.

Therefore, there is a need for a manure spreader that can load compost efficiently and at low cost.

[Purpose of the invention] In response to these demands, the present invention has been developed to improve the efficiency of loading and discharging (spreading) work by one person even on tractors that are not equipped with a lift arm that moves the hitch part up and down. The purpose is to provide a mania spreader that is easy to use and has high workability.

In order to solve the problems of the prior art, we conducted various studies and found that the present invention was developed by lowering the rear end of the compost box to the extent that the rear end of the compost box touches the ground. In this state, if the mania spreader is moved backward while driving the floor conveyor and the beater in the opposite direction, when the rear end of the compost box reaches the compost pile, the beater for spreading the compost will move. acts to scrape the compost into the compost box, and a floor conveyor for sending out the compost acts to transfer the compost scraped up by the beaters into the compost box, automatically displacing the compost. After realizing that it would be possible to load the compost into the compost bin, we developed a towed mania spreader with wheels attached to the vehicle body that can be moved up and down relative to the vehicle body, and suspended on the floor of the compost bin. The floor conveyor and the beater installed at the rear end opening of the compost box are configured so that they can be driven by switching the direction of rotation between forward and reverse, and are connected to a towing vehicle to achieve the above-mentioned state. When the car is reversed toward the compost heap, the compost is automatically loaded into the compost box, and the compost is subjected to the beater twice, once during loading and once when spreading. This is based on the fact that the accuracy of the spraying work was also improved.

Based on this, the present invention was developed by mounting a compost box on a towed vehicle body equipped with an input shaft and a connecting hitch on the front end and running on running wheels, and loading the compost box onto the floor of the compost box. A floor conveyor is installed to transport the compost later, and a beater is installed in the open opening at the rear of the compost box to spread the compost, and the operating shafts of the floor conveyor and the beater are connected to the input shaft. In the mania spreader, a forward/reverse device is installed between the input shaft and the operating shafts of the floor conveyor and the beater to switch the direction of rotation between forward and reverse. The wheels are mounted on a support member that moves up and down relative to the vehicle body, and a lifting device is interposed between the support member and the vehicle body, so that the rear end of the vehicle body can be lowered to the extent that the rear end side of the compost box reaches the ground. We aim to provide a mania spreader featuring the following.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.
Note that the same reference numerals in the drawings as in the conventional means are used for constituent members having the same effect.

FIG. 1 shows a perspective view of the Mania Spreader W. In the figure, the mania spreader W is a towed vehicle body 1 that is equipped with an input shaft 5 and a drawbar 6 on the front end side and is driven by running wheels 7, and has a compost bin 2.
A floor conveyor 3 is installed on the floor of the compost box 2 to transport the loaded compost later, and the transported compost is spread through the opening 2a opened at the rear of the compost box 2. The present invention is similar to the conventional one in that a beater 4 is installed, and the operating shafts 3a and 4a of the floor conveyor 3 and the beater 4 are transmitted to the input shaft 5. 8 is a drive shaft, 9 is a bevel gear, and 10 is a worm reducer.

However, in the mania spreader W, as shown in FIG.
is arranged at a position forward and away from the input shaft 5,
As shown in FIG. 1, the input shaft 5 and the floor conveyor 3
and between the operating shafts 3a and 4a of the beater 4,
Forward/reverse device 1 that switches the direction of rotation between forward and reverse.
It is equipped with 2. 12a is a forward/reverse switching handle, and 12b is a conduction cover.

In addition, in the mania spretzer W, as shown in FIG. A cylinder 14 is interposed between the vehicle body 1 and the rear end of the compost box 2 to reach the ground.
The rear end can be lowered. 13a is a fulcrum that is the base end of the support member.

The support member 13 is made of a frame (vehicle body) in advance.
1 needs to be set on a high floor, and at the same time, the vertical movement stroke of the axle 7a needs to be large, so the axle 7a has a predetermined length. As a result, when the frame is of a low-slung type, even if deep ruts are formed during loading of compost and the compost box 2 touches the ground to such an extent that it is impossible to retreat for loading the compost, the hydraulic cylinder 14 can move the frame 1. Can rise.

Reference numeral 15 is a hydraulic hose connected to a hydraulic system on the towing vehicle T side.

The connecting hitch 11 has pin holes 11 in the vertical direction.
It has a tongue-like shape (Fig. 1) that passes through the part a, and it is inserted loosely into the U-shaped hitch 16 on the towing vehicle side and fixed with the pin 17 (the second part).
3, the diameter of the pin hole 11a of the connecting hitch 11 on the mania spreader side is larger than the diameter of the pin hole 16a of the U-shaped hitch 16. A ball joint 18 is loosely fitted into the pin hole 11a of the connecting hitch 11, and the pin 17 passes through the ball joint 18. The ball joint 18 absorbs the twisting between the connecting bit 11 and the pin 17 at the hit point a when the vehicle body is raised and lowered.

In FIG. 2, reference numeral 19 denotes a PTO shaft on the side of the towing vehicle T, which is connected to the input shaft 5 of the mania spreader W via a universal joint 20. In FIG. 5, 21 is a scattering prevention cover, and 22 is a pile of compost (open pile compost).

Next, the operation of the embodiment configured as described above will be explained.

In the normal state, as shown in FIG. 4, the hydraulic cylinder 14 is extended and the axle 7a of the running wheel 7 is
The vehicle body 1 is positioned above and the compost box 2 is maintained horizontally.

When loading compost into the compost box 2, the hydraulic cylinder 14 is contracted and the rear end of the vehicle body 1 is lowered until the rear end of the compost box 2 reaches the ground, as shown in FIG. If the mania spreader W is moved backward while the floor conveyor 3 and beater 4 are driven in reverse rotation as shown by arrows A and B, the rear end side of the compost box 2 becomes a pile of compost, that is, an open pile of compost 22. When plunging into the compost bin, the beater 4 for spreading the compost acts to scrape the compost into the compost box 2, and the floor conveyor 3 for sending out the compost scrapes the compost scraped up by the beater 4 into the compost box 2. and automatically loads the compost into the compost box 2.

During this loading operation, if the running wheels 7 get stuck in a deep rut and the rear end of the compost box 2 bites into the ground and becomes immobile, the hydraulic cylinder 14 is extended to ensure that the rear end of the compost box 2 is always on the ground. Adjust to the extent that it does not bite.

Next, when the hydraulic cylinder 14 is activated to raise the rear end of the compost box 2, the compost box 2 will return to its normal horizontal position as shown in FIG.
In this state, the rotation of the floor conveyor 3 and the beater 4 is stopped, and the mania spreader W is advanced by the forward movement of the towing vehicle T, and is driven to the target field. If the mania spreader W is moved forward in the same manner without rotating the beater 4 in the forward direction, the compost sent later by the floor conveyor 3 will be spread onto the field by the beater 4.

The compost to be spread is divided into two parts: at the time of loading and at the time of spreading.
It is shredded by the action of the beater 4.

[Effect of the invention] As described above, the mania spreader according to the invention has the input shaft 5 and the connecting hitch 11 on the front end side.
A compost box 2 is mounted on a towed vehicle body 1 which is equipped with a towed vehicle body 1 and runs on running wheels 7, and a floor conveyor 3 for transporting the loaded compost is installed on the floor of the compost box 2. A beater 4 for dispersing the compost that is sent later is installed in the open opening opened at the rear of the compost box 2, and the floor conveyor 3 and the operating shaft 3 of the beater 4 are installed.
In the mania spreader in which the rotation direction is switched between normal and reverse, the rotation direction is changed between the input shaft 5 and the operating shafts of the floor conveyor 3 and the beater 4. Reversing device 12
is installed, and the running wheels 7 are mounted on a support member 13 that moves up and down with respect to the vehicle body 1, and the support member 13
A lifting device 14 is interposed between the compost box 2 and the vehicle body 1, and the rear end of the vehicle body 1 can be lowered to the extent that the rear end of the compost box 2 reaches the ground. By raising the running wheels 7 relative to the car body 1 and lowering the rear end side of the car body 1, the rear end side of the compost box 2 reaches the ground, and the floor conveyor 3 and beater 4 are moved backward while being reversed. As a result, compost loading work can be carried out efficiently and automatically, making it easier for one person to carry out the consistent work of compost loading, transporting compost, and spreading compost, and improving the accuracy of the spreading work. Furthermore, by adjusting the height of the running wheels 7 by operating the hydraulic cylinder 14, the positional relationship between the rear end of the compost box and the ground can be maintained properly when loading compost. This will allow the compost loading work to be carried out smoothly.
