Description

[Detailed description of the device]

[0001]

[Field of Industrial Application] The present invention is for feeding fertilizer while cleaning the feeding roll for feeding the fertilizer into the vertical fertilizer drop trough from the lower rear of the fertilizer tank of the multi-row fertilizer applicator with a rotating brush. The present invention relates to a fertilizer feeding device.

[0002]

2. Description of the Related Art A conventional fertilizer feeding device for a multi-row fertilizer applicator of this type has a device described in Japanese Utility Model Laid-Open No. 63-28313. This device has a large number of scraping pieces on the outer circumference. This is a configuration in which the planted drum is driven to rotate, and the scraping pieces feed out the fertilizer in the receiving box.

[0003]

In the fertilizer feeding device of the conventional multi-row fertilizer applicator, when the fertilizer sticks to the scraped piece due to the influence of humidity etc. depending on the type of the fertilizer, the fertilizer scratches the scrap. This is because the amount of fertilizer applied per one rotation of the drum gradually decreases as the work adheres to the discharged pieces or the scraped pieces are clogged between the scraped pieces, and the amount of fertilizer applied becomes insufficient.

[0004]

(A) shows an appropriate number of fertilizer applicators arranged side by side on the frame (1), and (2) is a fertilizer tank of the fertilizer applicator (A), which is fixed on the frame (1) and its fertilizer is applied. The fertilizer tank (2) and the opening (1
The receiving box (3) communicating with 2) is provided in a protruding manner. Although not shown, the opening (12) is provided with an opening / closing adjustment plate that is operated up and down. y (5) is roll shaft (6) in receiving box (3)
A plurality of lateral grooves (4) having a concave arc-shaped cross section are arranged side by side on the outer circumference of the feeding roll (5) arranged at appropriate intervals.

Reference numeral (13) is a support arm on both sides of the rotating brush (7), which is obliquely rearward and upward and protrudes upward from the receiving box (3), and the lower bases of the support arms (13) are placed on the fertilizer tank (2). Is attached to the lower part of the rotatably by the rod (14),
At the protruding upper end of each side support arm (13), the rotary shaft (1) of the rotary brush (7) arranged above the pay-out roll (5).
Both ends of 6) are rotatably fitted and both side supporting arms (1
The upper part of 3) is elastically pressed downward by the spring (15), and its rotating brush (7) is pushed into the bottom of the upper lateral groove (4) of the feeding roll (5).

Reference numeral (17) is an agitation and delivery shaft which is installed through the lower part of all the fertilizer tanks (2) and the central part of the transmission casing (10), and the fertilizer tank (2) of the agitation and delivery shaft (17). ), And the claws (18) are radially planted inside.
(19) is an output shaft that is arranged above and below the transmission casing (10).
Although not shown, the stirring and sending shaft (17) and the upper and lower output shafts (19) are connected by a speed change transmission mechanism in the speed change casing (10), and (20) is installed behind the speed change casing (10). It is the intermediate axis.

Reference numeral (21) is a fertilizer grooving device provided below the fertilizer tank (2). The discs on both sides are rotatably supported by arranging them in a C-shape that opens backward when viewed from above. . (22)
Is a fertilizer drop gutter which is vertically arranged with the upper opening facing the rear of the receiving box (3), and the lower end thereof faces the rear part of the fertilizer grooving device (21). Reference numeral (23) is a wheel frame provided with its front end fitted to the main shaft (11) and protruding rearward on both sides of the middle of the frame (1), and the wheel (24) is attached to each wheel frame (23).

It rotates due to the contact resistance with the roll (5).

Therefore, the fertilizer in the tank (2) is successively stirred and fed into the receiving box (3) through the opening (12) while being stirred by the stirring and feeding claw (18) of the shaft (17), The fertilizer enters the lateral groove (4) of the pay-out roll (5) and is lifted up and hit into the drop gutter (22).
The fertilizer is applied by flowing down from the lower end of 2) into the fertilizer application groove made by the groove cutter (21).

On the other hand, the rotating brush (7) enters the upper lateral groove (4) of the payout roll (5) to the bottom of the upper part of the lateral roll (4) to rotate in contact therewith, so that the rotary brush (7) is always provided with the lateral groove (4). The peripheral surface of (5) is cleaned to prevent the fertilizer from adhering to the feeding roll (5) with the lateral groove (4).

[0016]

The fertilizer feeding device of the multi-row fertilizer applicator of the present invention has the following advantages.

(1) A receiving box that communicates with the fertilizer tank is provided at the lower rear of the fertilizer tank, and a lower base is rotatably supported by a shaft rod above the driving roll with a lateral groove in the receiving box. The rotating brush is rotatably supported between the upward protruding tips of both attached support arms, and the rotating brush is pushed by its own weight and the elastic force of the spring to push it downward to the bottom of the upper lateral groove of the feeding roll. . Therefore,

(A) As the feeding roll rotates, the rotating brush comes into contact with the feeding roll and rotates to clean the outer periphery of the feeding roll and the inside of the lateral groove to the bottom. The amount of fertilizer applied can be kept constant by preventing it from adhering inside.

(B) The rotating brush is always properly inserted and held to the bottom in the lateral groove of the feeding roll by its own weight and the elasticity of the spring.

(C) Since the rotating brush enters the bottom of the lateral groove of the payout roll and rotates in contact therewith, the rotary brush can rotate smoothly and accurately to clean the inside of the lateral groove of the payout roll with good performance at all times.

(D) Since the rotating brush is located above the feeding roll, the feeding fertilizer by the feeding roll and the removed fertilizer by the rotating brush do not become clogged in the rotating brush, and the rotating brush is kept clean from beginning to end and properly To work.

(E) The vertical movement of the rotary brush is light and smooth.

(F) Whether or not the rotating brush has entered and hits the bottom of the lateral groove of the pay-out roll can be easily checked with the eyes, and the work can always be performed reliably.

(G) When the rotary brush is damaged or worn, the state of the damage or wear can be easily checked with eyes, and the rotary brush can be easily replaced, which is convenient for work. .

(2) The structure is simple and can be manufactured easily and inexpensively.
