Description

Oblique opposed disc side-throwing type organic fertilizer broadcast seeder

Technical Field

The invention belongs to agricultural fertilizing machinery, and mainly relates to an oblique opposed disc side-throwing organic fertilizer broadcaster.

Background

At present, no side-throwing fertilizer spreader is researched at home, and foreign researches are relatively few. The existing side-throwing fertilizer spreader takes a double-section screw feeder as a conveying part and staggered hammer sheets welded on a shaft as a key fertilizer spreading part, although the shortage of fruit tree forest fertilizer application can be solved by the fertilizer spreading mode, the side-throwing fertilizer spreader has certain defects that materials are laterally thrown out by means of impact force between the materials and the hammer sheets when the fertilizer spreader operates at high speed, and the impact force is large, so that the side-throwing fertilizer spreader with a soft spreading form is designed.

Disclosure of Invention

The invention aims to solve the problems, and the invention innovatively designs an oblique opposite disc side-throwing organic fertilizer spreader to solve the limitation of fertilization and avoid the problems that the existing side-throwing organic fertilizer spreader requires high hammer strength and the like.

The invention is basically designed to provide an obliquely-opposed disc side-throwing organic fertilizer spreader, which comprises a carriage, a transmission case, a high-position conveying auger, a low-position conveying auger, a chassis and a fertilizer spreading device, wherein the high-position conveying auger and the low-position conveying auger are arranged in the carriage; the disc mounting rack is arranged on the side surface of the carriage, and the left fertilizer spreading disc and the right fertilizer spreading disc are obliquely arranged on the disc mounting rack in an opposite mode; the power is derived from the hydraulic output of the tractor, and hydraulic oil is uniformly distributed to the first hydraulic motor and the second hydraulic motor through the synchronous valve to drive the left fertilizer spreading disc and the right fertilizer spreading disc to rotate; the left fertilizer spreading disc and the right fertilizer spreading disc are provided with fertilizer scraping plates; the disc mounting frame is connected with the air guide sleeve through a pin shaft, two ends of the hydraulic cylinder II are respectively hinged to the carriage and the air guide sleeve, and the air guide sleeve is driven to rotate around the pin shaft through the expansion of the hydraulic cylinder II; a baffle is arranged at the joint of the disc mounting frame and the carriage, two ends of the hydraulic cylinder are respectively fixed on the carriage and the baffle, and the baffle is driven to slide along the side face of the carriage through the extension of a piston rod of the hydraulic cylinder.

The invention can realize lateral fertilization, enhances the reliability of the device by the soft spreading form of the disc, and prolongs the service life of the product.

Detailed Description

The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings.

Two disc side formula fertilizer broadcast seeder of throwing of slope opposition comprises chassis, carriage, high-order transport screw feeder, low level transport screw feeder, disc mounting bracket, transmission case, left side spills fertile disc, the right side spills fertile disc.

When the device works, a piston rod of the first hydraulic cylinder 8 extends, the baffle 13 fixedly connected with the first hydraulic cylinder 8 also slides upwards along the carriage 4, at the moment, a discharge opening is opened, a power output shaft of a tractor transmits power to the first driving shaft 31 through the universal joint 1, the first driving shaft 31 transmits the power to the second driving shaft 32 through the meshing of the first gear 23 and the third gear 25, simultaneously transmits the power to the third driving shaft 34 through the meshing of the second gear 24 and the sixth gear 28, the second driving shaft 32 transmits the power to the high-position conveying auger shaft 33 through the meshing of the fourth gear 26 and the fifth gear 27, the third driving shaft 34 transmits the power to the low-position conveying auger shaft 35 through the meshing of the seventh gear 29 and the eighth gear 30, a part of materials at the upper end of the carriage 3 are conveyed to the first stirring sheet 16 along the directions of the right-turn helical blade 15 and the left-turn helical blade 17 of the high-position conveying auger, the first stirring sheet 16 conveys the fertilizer to, the other part of the materials are transported to the low-position transport auger 21 along the tangential direction of the helical blade of the high-position transport auger, and all the materials which are transported to the low-position transport auger 21 are transported to a discharge opening along the axial direction of the low-position transport auger 21; meanwhile, hydraulic oil is equally distributed to the first hydraulic motor 11 and the second hydraulic motor 14 through the synchronous valve 12 to drive the left fertilizer spreading disc 6 and the right fertilizer spreading disc to rotate 7, fertilizer is spread under the action of the fertilizer scraping plate 36, the oblique opposite installation aims to reduce a spreading surface, a guide cover 9 is designed for the spreading device, the guide cover 9 is hung with the disc installation frame 5 through a pin shaft 37, and the guide cover 9 can be controlled to rotate along the pin shaft 37 through extension and contraction of a piston rod of the second hydraulic cylinder 10 so as to change the position of the guide cover 9. The device is operated in the field by transporting the chassis 4.

When the device finishes working, the piston rod of the first hydraulic cylinder 8 is contracted, and the baffle 13 slides downwards to close the discharge opening.
