Abstract
Description
Technical Field
[0001] This invention belongs to agricultural machinery and mainly relates to a work platform for balers that integrates standing straw cutting, gathering, picking up and conveying operations. Background Technology
[0002] With the development, progress, and improvement of science and technology, crop straw, originally agricultural waste, has become an important raw material for livestock feed, biomass fuel, and organic fertilizer in agricultural production. my country is a major agricultural country, producing a huge amount of crop straw every year, and its recycling is a crucial link in the comprehensive utilization of crop straw. Currently, crop straw recycling in my country is mostly completed using traditional methods. This involves first using straw cutters to cut the straw standing on the field, then using raking equipment to collect the cut straw into strips, and finally using balers to collect and bale the straw. The large variety of equipment, long operation cycle, low efficiency, and high cost are significant and prominent technical problems. Summary of the Invention
[0003] The purpose of this invention is to address the problems existing in the prior art and, in light of the actual needs of current straw cutting, gathering, picking up, and conveying operations, to develop and design a combined straw cutting, gathering, picking up, and conveying workbench suitable for use with balers. This aims to reduce the number of supporting equipment, lower the cost of purchasing and operating machinery, shorten the operation cycle, improve operation efficiency, and facilitate operation.
[0004] The purpose of this invention is achieved as follows: A cutting and collecting motor is fixedly mounted on the upper front end of a Π-shaped frame via a horizontal support beam. A circular stepped groove plate is coaxially suspended on the lower side of the horizontal support beam, below the cutting and collecting motor. A drive shaft, mounted on the lower end of the motor shaft of the cutting and collecting motor, is axially and radially positioned and rotatably inserted into the central hole of the circular stepped groove plate. A circular base plate is fixedly mounted coaxially on the lower part of the drive shaft below the circular stepped groove plate. Multiple cutter tooth shafts are evenly distributed along the circumference, axially and radially positioned, and rotatably inserted into the circular base plate. A crank shaft is fixedly mounted on the inner end face of the cutter tooth shaft, and rollers are rotatably mounted on the crank shafts. The rollers are rollably snapped into the circular stepped groove of the circular stepped groove plate. A fixed circular saw blade and a flexible gathering nail tooth are arranged on the toothed shaft in a staggered manner with an angled arrangement along the circumference. A gathering side plate is installed on the inner wall of the right side panel of the Π-shaped frame. A bidirectional spiral conveyor and a spring-tooth pickup roller are installed parallel to each other and rotatably from top to bottom on the inner wall of the rear panel of the Π-shaped frame, behind the gathering side plate and the toothed shaft. The driving sprocket and the driven sprocket are fixedly mounted on the bidirectional spiral conveyor and the spring-tooth pickup roller, respectively. A chain is fitted on the driving sprocket and the driven sprocket. The pickup and conveying motor, which is fixed on the inner wall of the rear panel of the Π-shaped frame, is connected to the bidirectional spiral conveyor. Traveling support wheels are rotatably installed on the lower outer side of the left and right side panels of the Π-shaped frame. This constitutes a combined operating platform for straw cutting, gathering, picking up and conveying for a baler.
[0005] This invention scientifically and rationally combines the various operational stages of straw cutting, gathering, picking, and conveying onto a single frame, enabling joint operations of multiple tasks. It reduces the types and quantities of machinery to be purchased and configured for different tasks, and features a novel, unique, reasonable, and compact structure, high operational efficiency, short cycle time, low cost, good quality, convenient and reliable use, and strong compatibility with various applications. It provides technical support for crop straw recycling and comprehensive utilization. Attached Figure Description

[0015] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. A combined operating platform for cutting, gathering, picking up, and conveying straw in a baler comprises a cutting and gathering motor 2 fixedly mounted on the upper front end of a Π-shaped frame 7 via a horizontal support beam 17. A circular stepped groove plate 9 is coaxially suspended on the lower side of the horizontal support beam 17, below the cutting and gathering motor 2. A drive shaft 10, mounted on the lower end of the motor shaft of the cutting and gathering motor 2, is axially and radially positioned and rotatably inserted into the central hole of the circular stepped groove plate 9. A circular seat plate 11 is fixedly mounted coaxially on the lower part of the drive shaft 10 below the circular stepped groove plate 9. Multiple toothed shafts 13 are evenly distributed circumferentially on the circular seat plate 11, axially and radially positioned, and rotatably inserted. A crank shaft 9 is fixedly mounted on the inner end face of the toothed shaft 13. Rollers 18 are rotatably mounted on the crank shafts 19 and are rollably snapped into the circular ring. Within the annular stepped groove of the stepped groove plate 9, fixed circular saw blades 14 and elastic collecting nail teeth 12 are sequentially and interspersed with each other along the circumferential direction on the toothed shaft 13; a strip collecting side plate 16 is installed on the inner wall of the right side panel of the Π-shaped frame 7; a bidirectional spiral conveying auger 1 and a spring-tooth picking roller 15 are respectively installed parallel to each other and rotatably from top to bottom on the inner wall of the rear panel of the Π-shaped frame 7, located behind the strip collecting side plate 16 and the toothed shaft 13; a driving sprocket 4 and a driven sprocket 5 are respectively fixed on the bidirectional spiral conveying auger 1 and the spring-tooth picking roller 15; a chain 3 is fitted on the driving sprocket 4 and the driven sprocket 5; a picking and conveying motor 6 fixed on the inner wall of the rear panel of the Π-shaped frame 7 is connected to the bidirectional spiral conveying auger 1; and walking support wheels 8 are respectively rotatably installed on the lower outer side of the left and right side panels of the Π-shaped frame 7.
[0016] During operation, this combined work platform is mounted on the front end of the baler using a Π-shaped frame 7. With the walking support wheels 8 in contact with the ground, the platform moves forward with the traction power machinery. At the same time, the cutting and gathering motor 2 and the picking and conveying motor 6 are started. The cutting and gathering motor 2 drives multiple toothed shafts 13 to revolve around the axis of the drive shaft 10 via the drive shaft 10 and the circular seat plate 11. While the circular saw blades 14 on the toothed shafts 13 complete the cutting operation of the straw standing on the field, the circular stepped groove plate is fixed in place. The moving roller 18 within the annular stepped groove 9 tilts and rotates. This tilting roller 18, via a crank shaft 19, drives the toothed shaft 13 to rotate on the circular base plate 11. This causes the circular saw blade 14, which has already completed its cutting operation, to rotate upwards and disengage from the ground. Simultaneously, the elastic gathering teeth 12 rotate downwards, pushing the cut straw towards the gathering strip side plate 16. Then, the picking and conveying motor 6 drives the rotating spring-tooth picking roller 15 to pick up the straw, which is then conveyed by the bidirectional spiral conveyor auger 1 to the baling mechanism at the rear, completing the baling operation. The toothed shaft 13, through the roller 18, crank shaft 19, and under the coordinated control of the annular stepped groove plate 9, continuously and repeatedly oscillates in a circular direction, completing the sequential and continuous switching between the working and non-working positions of the circular saw blade 14 and the elastic gathering teeth 12, i.e., the switching between straw cutting and gathering operations.
