Description

Manure spreader for tractor attachment. {COMPOST SPRINKLER FOR TRACTOR}

The present invention relates to a compost spreader, in particular to a tractor attached compost spreader to be mixed with various compost and fertilizer, such as being towed to the farmland will be.

Typically, compost is fermented by mixing sawdust, rice husk, weeds and the like in the livestock manure, the compost is agglomerated large or small. There are a plurality of spreaders for the purpose of spreading the compost to the arable land, the conventional spreaders are mainly mounted on a variety of agricultural vehicles such as a tractor and transported, and the compost by the rotary shaft and hydraulic pressure provided in the agricultural vehicle It has a means of operating the conveying conveyor or spreading the compost operated by the conveyor.

Such conventional spreaders, due to the complex structure of the heavy weight is easy to damage the arable land and the purchase cost is high and can not be activated in the farm. In addition, the means for crushing the composted aggregates are weak and difficult to spread so as to be uniformly distributed, and in particular, there is no means for spraying with a mixture of chemical fertilizer.

In order to solve the above problems, there is a multi-purpose compost spreader (Patent registration No. 53044) registered by the same inventor as the present applicant (hereinafter referred to as a proposal).

However, the cited proposal is driven by the power connected to the rotating shaft of the tractor, it is not easy to mount, frequently breakdown and breakage occurs, and makes a lot of noise. In particular, when the rotary shaft of the tractor is used in connection with other farming equipment, there is a problem that can not be used.

Accordingly, an object of the present invention is to provide a tractor attachment compost spreader having a relatively simple structure and durable.

Another object of the present invention is to provide a compost spreader for tractor attachment that can be sprayed by mixing with other fertilizers, as well as compost.

Still another object of the present invention is to provide a compost spreader for attaching a tractor that can be sprayed so as to be uniformly distributed over the front of the farmland in spreading the compost.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in describing the present invention, if a detailed description of a related known function or configuration may obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a perspective view showing the configuration of a compost spreader according to an embodiment of the present invention. According to the drawings, there is a door 10 for injecting contents such as compost and fertilizer on one side and a housing having a rotary that is rotated by an axial rod therein, and a hydraulic motor for rotating the shaft of the rotary to the other side of the housing (36) and the reducer (30), and a hopper formed in the lower portion of the housing and the damper (52) and lever (64) capable of opening and closing the inlet of the hopper and the contents while rotating inside the hopper. It is composed of an impeller 40 having a wing that is crushed and sprayed to the arable land.

According to Figure 2 is a central cross-sectional view of the compost duster of the present invention, the rotary motor 20 inside the housing 10 is rotated by the hydraulic motor 36 and the reducer 30.

And, Figure 3 and Figure 4 is a front view and side view of the subject innovation, the impeller 40 with wings 42 inside the hopper is rotated while being connected to the reducer 30 and the chain 2, the lever 64 ), Opening and closing the damper 52 between the housing and the hopper. Is showing.

Referring to the main body 1 configured in this way in more detail as follows.

In the housing 10 into which the compost to be sprayed is introduced by the door 12 on one side, a rotary 20 for mixing or crushing compost is inserted. The rotary 20 is fixed to the shaft 22 in the center, one side (right side in the drawing) of the shaft bar 22 is supported on one side of the housing and the bearing fixture 24, the other side (left side in the drawing) is It is connected to the shaft and the joint 26 in the reducer 30. The lower portion of the reducer 30 is connected to a hydraulic motor 36 driven by the hydraulic hose 38 of the injection and discharge. Meanwhile, the shaft 32 inserted into the reducer 30 is connected to the shaft 22 inward to rotate the rotary 20, the other end protrudes to the outside, and the chain gear 34 is fixed to the end. . Here, the chain gear 34 is for driving the impeller 40 for composting spraying in the lower part, which will be described later.

Next, a hopper 16 opened forward is attached to the lower portion of the housing 10, and a damper 52 is opened between the housing 10 and the hopper 16 to open and close the passage. The damper 52 has a rack gear 52a attached to one side thereof, and a pinion 56 engaged with the damper 52 is fixed to the side surface of the housing 10. At this time, the pinion 56 has a shaft 50 in the center, penetrates to the side of the housing and the gear 54 is assembled at the end. There is a wheel shaft 60a fixed to the housing 10 above the gear 54, and at the end of the wheel shaft 60a there is a wheel 60 assembled by a boss 60b and an arm. The wheel 60 is a fan-shaped shape that rotates about the wheel shaft 60a to the outer peripheral surface of the gear 62 Is formed and is meshed with the gear 54 assembled with the pinion 56. In addition, a lever 64 facing backward is attached to the upper portion of the boss 60b.

Subsequently, an impeller 40 in which the shaft bar 46 is assembled to the inside of the hopper 16 is assembled, and on the right side, the shaft bar 46 protrudes so that the chain gear 44 is assembled to the end thereof. A plurality of wings 42 are fixed to the outside of the impeller 40 by welding while maintaining a constant interval, if the wing 42 is made of a resin when the wings collide with the stones and metals included in the compost (42) can be prevented from being damaged. Subsequently, the chain gear 44 is connected to the chain gear 34 and the chain 2 assembled to the above-described reducer 30. Meanwhile, legs 14 supporting the main body 1 are attached to both lower portions of the housing 10.

Referring to the operating state of the present invention compost spreader configured as described as follows.

First, at the rear of the housing 10 configured as shown in FIG. 1, there is a connecting means for towing in a conventional tractor not shown in the drawing, and the tractor pulls the main body 1 by the connecting means. Will move. At this time, the compost and chemical fertilizer, etc. should be introduced into the housing 10 by the side door 12, and the hydraulic motor 36 and the reducer 30 operate according to the operation of the tractor. Therefore, as the rotary 20 inside the housing rotates to mix the contents therein, the impeller 40 receiving the rotational force of the hydraulic motor 36 by each of the chain gears 34 and 44 and the chain 2 is Will rotate.

When the main body 1 operated in this way is moved to the arable land to be composted by the tractor, the tractor driver pulls the lever 64 of the main body 1 to open the damper 52. Turn on. At this time, the wheel 60 is rotated by the operation of the lever 64, the lower gear 54, the shaft 50 and the pinion 56 is rotated, the pinion 56 is a damper 52 The damper 52 is opened while moving the rack gear 52a attached thereto.

As the damper 52 is opened, compost and the like in the housing 10 are discharged out by the impeller 40 which is moved to the hopper 16 and rotated.

When spraying in this way, when the spray is to be stopped for a while, the lever 64 is lifted upward, so that the damper 52 blocks the inside of the housing and the spraying is stopped.

As described above, the present invention can be sprayed in a single operation by mixing the compost and chemical fertilizer, and has the effect of reducing manpower and work time, the power means by the hydraulic reducer is less noise, In some cases, the direction of rotation can be reversed, and even if the load is caused by impurities, the reducer will run idle and will not overload the device. In particular, the present invention is relatively simple and excellent in durability, with a low failure rate and economical effect of lowering the manufacturing cost.
