It is composed.

This invention by the above configuration is possible to run and fertilizer spraying work in the state mounted on the tractor by the three-point support method, free to rotate and run, and to enable a narrow range of fertilizer spraying work, by the PTO shaft and hydraulic pressure of the tractor By driving the spreading fan and the conveyor belt, it is possible to stably perform the spreading operation of the organic fertilizer having a high viscosity.

Description

Tractor-mounted organic fertilizer spreader {Tractor-loading spreader for an organic fertilizer}

The present invention relates to a fertilizer spreader for use in agricultural machinery such as tractors, and more specifically, to operate the conveyor belt by operating the hydraulic motor with the hydraulic pressure provided from the tractor in the state lifted by the tractor by the three-point link method The present invention relates to an organic fertilizer spreader which drives the spreading fan by the power from the shaft to efficiently transport and spread the organic fertilizer in the hopper.

Organic fertilizers are used to remove poultry meal, by-products from composts, and compost. These organic fertilizers are highly viscous and entangled with each other.

However, the conventional organic fertilizer spreader is towed to a large tractor in the form of a trailer to enable fertilizer spraying is very difficult to rotate and drive maneuver is suitable for the fertilizer spraying of a large area, but not suitable for the fertilizer spraying in a narrow area, There is a problem that it is expensive and not suitable for the tractor capacity widely distributed in Korea.

The present invention makes it easy to operate and spread the work by spraying the fertilizer and the spraying in the state mounted on the tractor by binding to the upper link and the lower link installed at the rear of the tractor. By driving the spreading fan and the conveyor belt by the hydraulic pressure and the driving force from the PTO shaft, the organic fertilizer spreading work is simply and effectively made possible.

1 to 4 are for showing the basic configuration of the subject innovation, the subject innovation is a rectangular hopper (1) formed with a fertilizer outlet (1a) at the bottom, the hydraulic motor (2a) is installed in the lower portion of the fertilizer outlet (1a) (2) driven conveyor belt (2), spreader fan (3) installed at the lower part of the conveyor belt projecting outward and driven by power from the tractor PTO shaft, and fertilizer blocking installed inside the spreading fan. Plate 4, L-shaped frame 5 adapted to support hopper 1, conveyor belt 2 and spreading fan 3, respectively, and one upper link coupler 6 formed in front of the frame. And two lower link couplers (7) (7 ').

The hopper 1 is for loading fertilizers, and the bottom portion is inclined for a smooth discharge of the fertilizer, and the bottom has a configuration in which a fertilizer outlet 1a in the longitudinal direction is formed.

The conveyor belt (2) is for transporting fertilizer in the hopper (1) to the spraying pan (3), and supports the rubber belt (2b) and the rubber belt having a width slightly larger than the width of the fertilizer outlet (1 a) It is composed of a roller 2c, a belt pulley 2e provided at both ends of the conveyor frame 2d, and a fertilizer mill 2f attached laterally on the belt. The hydraulic motor 2a is coupled to one belt pulley. It is driven, and performs a function to allow the fertilizer falling to the fertilizer outlet by its own weight to the top of the spreading pan while pushing the fertilizer.

The spreading fan 3 is for spreading a wide range by striking the spilled fertilizer and is composed of a disc 3b attached to a vertical axis 3a connected to the gearbox 8 and a blade 3c attached to the disc. do.

The spreading fan is configured to utilize power from the PTO shaft 9 of the tractor, specifically as shown in FIG. 6, the power transfer to the spreading fan is coupled to the horizontal spline shaft 8a of the gearbox 8. The coupling shaft 10 is coupled to the PTO shaft 9 of the tractor.

The horizontal spline shaft (8a) of the gearbox, the connecting shaft (10) and the PTO shaft (9) of the tractor are joined using a joint (universal joint) (11) (11 '), and the connecting shaft has a support bearing (in the middle). 12) to support the frame to prevent other rolling on the load.

The fertilizer blocking plate 4 is formed inside the spreading pan to prevent the fertilizer spreading by the spreading pan from being scattered to the tractor side.

The upper link coupler (6) and the lower link coupler (7) (7 ') are for mounting the fertilizer spreader to the tractor is formed in front of the frame, respectively, the upper link (20) and lower link (21) of the tractor It is coupled to the three-point support state to lift the spreader in the state to act to enable the operation and spreading work.

FIG. 6 is a diagram illustrating a fertilizer conveying and spreading process, in which fertilizers carried by a conveyor belt collide with a spreading pan rotating simultaneously with a drop at the belt end to be spread to a wide range.

Figure 7 is to show the mounting state of the fertilizer spreader according to the present invention is to show that the running and fertilizer spraying is made in the state mounted on the tractor in a three-point support state by the upper and lower links.

The present invention is capable of driving and fertilizer spraying while mounted on the tractor by a three-point support method, which enables free rotation and driving, and enables a narrow range of fertilizer spraying. By driving and driving the conveyor belt by the hydraulic motor, it is possible to stably carry out the spraying of organic fertilizer with high viscosity, and the simple structure of the device makes manufacturing cost less, and it is possible to perform the organic fertilizer spraying economically. Has an effect.
