The present invention relates to a hydraulic multi-purpose fertilizer spreader for spraying fertilizers or composts mounted on agricultural machinery such as tractors, more specifically, organic fertilizers or compost by driving the conveyor, screw, and spreading fan simultaneously with hydraulic power provided from the tractor A hydraulic multi-purpose fertilizer spreader for manure or composting.

In general, the fertilizer spreader is installed at the rear of the tractor to supply fertilizer to the hopper-shaped storage tank, and then discharge the fertilizer to the lower side by using the centrifugal force of the spreading device rotating at high speed evenly within a certain range. The device is designed to be sprayed.

The device of this structure is suitable for spraying chemical fertilizer, which is smoothly spilled even with a slight vibration because the thickness of the kernel is constant and the cohesive strength of each other is weak, but it is highly viscous and strong cohesive organic fertilizer such as flour, soil, sawdust, lime, etc. In the case of it is difficult to spray naturally because the proper amount is difficult to flow to the lower side was a problem.

In addition, the power connection structure of the conventional multi-purpose fertilizer spreader is a structure that directly connects the PTO shaft of the tractor and the drive shaft of the fertilizer spreader, the power transmission is made mechanically, there is an advantage that the power transmission is sure and delivers a large force. In this case, the power loss due to the resistance of the shaft itself is large, the rotating element is exposed, and the risk of safety accidents is caused, and the PTO shaft with the tractor is displaced when the manipulator sprayer is lifted. There is a dangerous problem in the transmission of force as the width gap is small, and the shaft connection is frequently missed.

The hydraulic motor is used to directly connect to the fertilizer spreader, or to connect the hydraulic pressure made by the tractor through a hose using a lot of hydraulic, but the hydraulic is designed to obtain a suitable hydraulic pressure by intermittent linear movement like a cylinder In the case of a mechanism that obtains a rotational drive by constantly circulating the hydraulic pressure, such as a hydraulic motor, the output is not high with time, there is a problem that the efficiency is lowered.

The present invention is a conveyor for transporting and dropping organic fertilizers such as powder, soil, and sawdust to the center of the bottom of the hopper in addition to the general fertilizer, and a screw for discharging the fertilizer dropped by the conveyor to the outlet by spiral motion; It is composed of a spreading fan for dispersing the fertilizer discharged by the screw widely, it is designed to spread the fertilizer or compost.

 In addition, the present invention by rotating the shaft of the conveyor, screw, and spreading fan to each other, the three devices are driven at the same time to increase the efficiency of the work, by adjusting the rotation speed by varying the size of the gear installed on the shaft The purpose of this study is to reduce the amount of fertilizer drops, discharges and sprays, and to ensure good connectivity.

In addition, the present invention is installed so that the hydraulic motor is connected directly to the conveyor shaft, and then connecting the connecting jack to the tractor in the hydraulic motor to supply the hydraulic pressure, even if the fertilizer spreader is frequently flowed, the connection jack is firmly fixed to the hydraulic motor, so that the power transmission is stable. It is designed to be possible.

In addition, the present invention is designed to be able to adjust the fall amount by adjusting the opening width in accordance with the type and size of fertilizer transported to the center by installing a drop adjustment device in the center of the bottom of the hopper.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows the overall appearance of the subject innovation, Figure 2 is a plan view of the subject innovation, Figure 3 is a cross-sectional view of the subject innovation.

The drop control device 11 is installed in the lower center of the inside of the hopper 10 to adjust the drop amount of the fertilizer or compost, the drop control device 11 of the illustrated example is front and rear as shown in Figs. The control shaft (11a) is installed in the longitudinal direction of the one side is connected to the control shaft (11a) and a pair of wing plates (11b) flowing up and down by the rotation of the control shaft (11a), and the wing It consists of a case (11c) covering the plate (11b) and the control shaft (11a) to protect from fertilizer or compost, and a lever (11d) is provided outside the hopper 10 to adjust the rotation angle of the control shaft (11a). According to the type of fertilizer or compost by the drop adjusting device 11, the user operates the lever 11d to adjust the rotation angle of the control shaft 11a and flow up and down the wing plate 11b to convey the conveyor 21. Adjust the fall amount of fertilizer or compost moved to the center by.

Dropping device 20 is installed in the lower portion of the inside of the hopper 10, it is composed of a pair facing each other, respectively rotated inward by the power of the conveyor 21 to drop the fertilizer or compost to the center,

Located in the lower portion between the conveyor 21, is installed to equilibrate in the concave groove of the bottom of the hopper 10, the screw 22 for discharging the fertilizer or compost to the outlet of the hopper 10 by the spiral movement,

It is installed in the lower portion of the outlet of the hopper 10, and is composed of a spraying pan 23 is sprayed with fertilizer or compost, the conveyor 21, the screw 22 and the spreading pan 23 is connected to the conveyor 21 It has a power connection line driven at the same time by the rotation of the installed hydraulic motor (50).

Conveyor 21 is to drop the fertilizer or compost stored in the hopper 10 while pushing to the outlet located on the bottom of the hopper 10, the fertilizer or the compost of the belt protrudes the upper side so that the transport force is good, The frame is fixed to the belt, the shaft is provided on both ends of the frame and the pulley and the chain 40.

The conveyor 21 of the above structure is provided in pairs facing each other, and the conveyor shafts 21a and 21a 'adjacent to the pair facing each other are engaged by the gears 21b and 21b' and driven by a rotational force simultaneously driven inward. Fertilizer or compost is dropped to the bottom of the hopper 10 between the conveyors 21. The conveyor belt of the illustrated example is installed horizontally, and in addition to the illustrated form, the conveyors 21 on both sides may be inclined toward the center to make the fertilizer or compost fall more smoothly.

The lower end of the left and right sides of the hopper 10 is formed to be spaced apart from the belt so that the belt protruding from the upper side of the conveyor 21 is not caught, and the conveyor 21 is reversed by reversing the rotation direction of the hydraulic motor 50. By rotating left and right, fertilizers or composts can be spread through the gaps.

 The screw 22 is installed at the bottom of the hopper 10, and consists of a screw wing in one direction to move the fertilizer or compost to the outlet formed on the rear side of the bottom of the hopper 10 by the spiral movement in one direction. In the embodiment, the concave groove of the “U” shape is formed at the bottom of the hopper 10 to install the screw 22 therein.

As such, the process of moving the fertilizer or the compost by using the conveyor 21 and the screw 22 is performed in a double manner to smoothly discharge the fertilizer or the compost.

The spreading fan 23 is to spread the fertilizer or compost that is carried by the screw 22 and discharged to the outlet to a wide range, and is located at the lower portion of the outlet of the hopper 10, which is installed on the shape of the disk and Consists of a plurality of blades, the embodiment is a gearbox on the other side of the horizontal shaft 23b is connected to the screw shaft 22a and one side is connected to the chain 40, the screw fan 22 consisting of three blades having a hemispherical panel form It shows what is directly connected to (23a).
