Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and more specifically, to a combined machine for fruit tree pruning and residual branch crushing and recovery. Background Art

[0002] Winter pruning of fruit trees is a key link in orchard management and is a highly seasonal and labor-intensive job. At present, the pruning of fruit trees such as red dates, apples and pears is still mainly done manually, assisted by pruning tools, and mainly uses some auxiliary pruning tools (electric scissors, pneumatic scissors or hydraulic scissors). Fruit farmers hold or carry them on their backs to perform single-branch selective pruning of fruit trees. It is not suitable for large-scale orchards, has high labor intensity and low pruning efficiency. Existing pruning machines are mainly tree shaping pruning machines, including reciprocating cutting pruning machines, serrated disc pruning machines, and rotary knife pruning machines. They can only complete the shaping and pruning of the contours of the fruit tree crowns, but cannot achieve thinning and pruning inside the crowns of jujube trees. The ventilation and light transmittance inside the crowns after shaping and pruning are poor, which affects the yield and quality of the fruit. The residual branches after pruning are scattered on the ground, and they are mainly picked up and transported out of the garden by hand and piled up in the field, which takes up a large space and cannot be used directly; the existing residual branch crushers are divided into fixed and mobile types, and mainly adopt rolling cutting and crushing methods. The applicable branch diameter range is small, and it is difficult to achieve fast and effective crushing of hard and thick branches, which is easy to cause blockage and damage to working parts. Therefore, it is urgent to invent a fruit tree pruning and residual branch crushing and recovery combined operation machine to solve the above problems.

[0019] like Figures 1 to 9 As shown, the present invention provides a combined machine for fruit tree pruning and residual branch crushing and recovery, comprising: Walking scooter 100; The pulverizing device 200 is provided with a pulverizing shell 201 installed at the front end of the chassis 106 of the walking locomotive 100, and a feeding roller 202 and a pulverizing roller 203 rotatably installed in the pulverizing shell 201 in a front-to-back diagonal distribution. A feeding port is provided at the bottom of the front end of the pulverizing shell 201, and a discharge port is provided at the top of the rear end. A conveying pipe 204 is hinged on the outer side of the discharge port. The feeding roller 202 is close to the feeding port, and the pulverizing roller 203 is close to the discharge port. The feeding roller 202 and the pulverizing roller 203 are connected to a driving motor 205. The front end of the feeding port of the pulverizing shell 201 is connected to a collecting table 206, and a conveyor belt 207 is provided on the top of the collecting table 206 for transmitting in a direction close to the feeding port.

[0020] The fruit tree pruning and residual branch crushing and recycling combined operation machine described in the above technical solution includes a walking locomotive 100 and a crushing device 200, and the crushing device 200 is installed at the front end of the walking locomotive 100. The crushing device 200 is provided with a sturdy and durable crushing shell 201, and a feeding roller 202 and a crushing roller 203 are installed in the crushing shell 201. The feeding roller 202 is close to the feeding port opened at the front bottom of the crushing shell 201, which is responsible for initially guiding the collected residual branches into the crushing area; while the crushing roller 203 is close to the discharge port opened at the top of the rear end, and uses a high-speed rotating blade or hammer to strongly crush the residual branches and convert them into fine particles or powder. The feeding port is designed to be spacious and easy to align, so as to quickly receive a large number of pruned residual branches. A conveying pipe 204 is hinged on the outside of the discharge port, and the conveying pipe 204 can be designed to be retractable and adjustable in direction, so that the crushed materials can be directly transported to the designated collection container, reducing the steps of manual handling and improving work efficiency. The feeding roller 202 and the crushing roller 203 are powered by a high-performance driving motor 205. At the front end of the feeding port of the crushing shell 201, a wide collecting table 206 is provided, and a conveyor belt 207 is installed on the top of the collecting table to transmit in the direction close to the feeding port. This design uses the conveyor belt 207 to transport the branches that have been pruned and fallen on the collecting plate to the feeding port, and then automatically feeds them into the crushing device 200. The feeding and crushing of the branches are realized by the feeding roller 202 and the crushing roller 203. The whole process is smooth and efficient, which greatly reduces the physical burden of the operator. The fruit tree pruning and residual branch crushing and recycling combined operation machine provided by the present invention has a reasonable structural design. The positions of the feeding roller 202 and the crushing roller 203 in the crushing shell 201 are designed to be diagonally distributed front and back. The feeding roller 202 is close to the feeding port, and generates friction with hard and thick branches during rotation, so that the hard and thick branches can be grasped and pushed in the direction of the crushing roller 203. The crushing roller 203 is close to the discharge port and has a more powerful power and a sharper structure. When the hard and thick branches are pushed by the feeding roller 202, the crushing roller 203 generates a strong shear force and an extrusion force through its own rotational motion, and cuts, squeezes, tears, and other actions on the hard and thick branches, so that the structure of the hard and thick branches is destroyed, and then crushed. In addition, the crushing roller 203 is close to the discharge port opened at the top of the rear end of the crushing shell, so that the crushed branches are promptly transmitted from the conveying pipe 204 through the discharge port to avoid blockage in the crushing shell, thereby realizing the rapid collection, efficient crushing and convenient recycling of pruned branches, improving the automation level of orchard management, and effectively promoting the resource utilization of orchard waste.

[0021] In another technical solution, a trimming device 300 is also included, and the trimming device 300 is provided with a rotating column 301 rotatably mounted on the top of the chassis 106 of the walking locomotive 100, and the top of the rotating column 301 is hinged with a cantilever 302, and a first hydraulic cylinder 303 is hinged between the rotating column 301 and the side wall of the cantilever 302, and a connecting frame 304 is fixedly connected to the free end of the cantilever 302, and a telescopic column 305 is slidably penetrated at the top and bottom of the connecting frame 304, and a second hydraulic cylinder 303 is connected between the two telescopic columns 305 and the side wall of the connecting frame 304. 06, the connecting frame 304 and the two telescopic columns 305 are vertically hinged with a mechanical arm 307, a gas spring 308 is hinged between the side wall of each mechanical arm 307 and the side wall of the corresponding connecting frame 304 or telescopic column 305, and a supporting cutter disc 309 is fixedly provided at the free end of each mechanical arm 307, and the top and bottom of the supporting cutter disc 309 are respectively coaxially connected with an upper cutter disc 310 and a lower cutter disc 311, and a motor 312 is installed on each mechanical arm 307, and the rotating shaft of the motor 312 is connected to the rotating shafts of the upper cutter disc 310 and the lower cutter disc 311 through a belt drive. In the present technical solution, the pruning device 300 is installed on the front right side of the walking vehicle 100 through a rotating column 301 and a cantilever 302, and a plurality of motors 312 are distributedly installed on a plurality of mechanical arms 307. The upper blade disc 310 and the lower blade disc 311 installed at the free end of the mechanical arm 307 are driven by a belt in the mechanical arm 307 to rotate synchronously. The gas spring 308 is hinged on the mechanical arm 307 and the corresponding connecting frame 304 or telescopic column 305, so that the mechanical arm 307 can be elastically rotated within a certain range. By the telescopic action of the second hydraulic cylinder 306, the distance between the three mechanical arms 307 can be adjusted, and then the pruning height can be adjusted to achieve layered pruning. By adjusting the telescopic action of the first hydraulic cylinder 303, the pruning height can be adjusted. By adjusting the rotation angle of the rotating column 301, the pruning distance of the fruit tree can be adjusted, thereby improving the flexibility and applicability of the pruning device 300.

[0022] In another technical solution, the side wall of each mechanical arm 307 is provided with a plug plate 313 extending vertically outward, and the plug plate 313 is provided with a plurality of plug holes, and one end of each gas spring 308 is hinged to the side wall of the corresponding connecting frame 304 or telescopic column 305, and the other end is vertically provided with a plug rod that can be matched and plugged into any plug hole. In this technical solution, by plugging the plug rod into different plug holes, the connection position of the gas spring 308 and the connecting frame 304 or telescopic column 305 can be adjusted, and then the elastic rotation range of the mechanical arm 307 can be adjusted, thereby improving the flexibility and applicability of the trimming device 300.

[0023] In another technical solution, the outer periphery of the roller body of the feeding roller 202 is evenly distributed with a plurality of convex ridges 208 extending in the axial direction, and the outer end surface of each convex ridge 208 is evenly distributed with a plurality of convex teeth 209. In this technical solution, each convex tooth 209 is composed of a rectangular body and a quadrangular prism whose longitudinal section is an isosceles trapezoid. The design of the convex ridges 208 and the convex teeth 209 enables the feeding roller 202 to more effectively grasp and pull the pruned branches when rotating. The structure of these convex ridges 208 and the convex teeth 209 increases the friction between the roller body and the branches, so that the branches can be more smoothly guided into the space where the crushing roller 203 is located, thereby greatly improving the feeding efficiency. In orchard pruning operations, the shapes and sizes of the branches are often different, some may be slender, while others may be thick. The arrangement and combination of the convex ridges 208 and the convex teeth 209 can better adapt to these branches of different shapes and reduce the risk of blockage caused by the stuck branches. Even if encountering larger residual branches, the protruding teeth 209 can also play the role of breaking and combing, making it easier to feed into the crushing device 200, reducing the risk of blockage. In addition, the ridges 208 and the protruding teeth 209 on the feeding roller 202 can also perform preliminary breaking and combing of the residual branches while feeding the residual branches into the crushing device 200. This helps to reduce the burden of the crushing roller 203, improve the crushing efficiency, and make the crushed materials more uniform and fine.

[0024] In another technical solution, multiple rows of axially extending crushing components are evenly distributed on the outer periphery of the roller body of the crushing roller 203, each row of crushing components includes multiple crushing hammers, and the crushing hammers on the two adjacent rows of crushing components are staggered. Each crushing hammer is provided with a mounting seat 210 and a crushing hammer claw 211, and the mounting seat 210 is fixedly connected to the roller body of the crushing roller 203, and both ends of the mounting seat 210 extending in the axial direction are provided with support frames extending outward perpendicular to the roller body of the crushing roller 203, and the crushing hammer claws 211 are fixedly installed between the two support frames of the mounting seat, and the free end of each crushing hammer claw 211 is bent.

[0025] In the present technical solution, the arrangement of multiple rows of crushing components on the crushing roller 203 enables the residual branches to be subjected to more impacts and shearing effects when passing through the crushing area, thereby accelerating the crushing speed and improving the crushing efficiency. At the same time, the crushing hammers on the two adjacent rows of crushing components are arranged in a staggered manner, ensuring that the residual branches can be crushed more evenly and comprehensively during the crushing process, avoiding the phenomenon of incomplete crushing or blockage caused by excessive local force. Each crushing hammer is carefully designed with a mounting seat 210 and a crushing hammer claw 211. The mounting seat 210 is fixedly connected to the roller body of the crushing roller 203 to ensure the stability and reliability of the crushing hammer. The arrangement of the support frame enables the crushing hammer claw 211 to extend outward perpendicularly to the roller body of the crushing roller 203, forming a certain spatial structure, so that the crushing hammer claw 211 can more effectively capture and crush the residual branches during the rotation process. In particular, the curved design of the free end of the crushing hammer claw 211 not only increases the contact area between the hammer claw and the residual branches, but also improves the crushing force and efficiency of the hammer claw, making the crushed material more delicate and uniform. The crushing hammer claw 211 is made of high-strength material, which can withstand greater impact force and wear, and extend the service life of the crushing roller 203. At the same time, the design of the mounting seat 210 and the support frame also fully considers the principles of mechanics, so that the crushing hammer can better disperse and transmit force when subjected to impact force, avoiding damage caused by stress concentration. The staggered arrangement of the crushing components on the crushing roller 203 and the curved design of the crushing hammer claw 211 not only improve the crushing efficiency, but also help to reduce noise and vibration during the operation. This is because the staggered crushing hammers can make the residual branches receive more uniform and dispersed impact force during the crushing process, reducing the noise and vibration caused by excessive local force. At the same time, the curved design of the crushing hammer claw 211 can also better absorb and disperse the impact force, further reducing the generation of noise and vibration. The precise design and arrangement of the crushing components on the crushing roller 203 not only improve the crushing efficiency and effect, but also help to improve the safety of the operation. This is because the staggered arrangement of the crushing components and the curved design of the crushing hammer claws 211 can reduce the splashing and bouncing of the residual branches during the crushing process, reducing the potential risks to the operator and the surrounding environment. In short, the design of multiple rows of crushing components and staggered crushing hammers on the crushing roller 203 enables the crushing hammers to rotate at high speed when the crushing roller 203 is driven by the driving motor 205. Due to the centrifugal force of the crushing hammer claws 211, it will produce a strong impact force on the hard and thick branches. For hard and thick branches, they will first be hit by the high-speed rotating crushing hammer claws 211, and this impact force will cause cracks or breakage on the surface of the hard and thick branches. As the crushing roller 203 continues to rotate, due to the bending and staggered arrangement of the crushing hammer claws 211, they will hit the hard and thick branches multiple times from different angles and positions. Under continuous attacks, the hard and thick branches will gradually be broken into smaller fragments.Moreover, due to the shape and distribution of the crushing hammer claws 211, they can penetrate deep into the hard and thick branches and destroy their internal structure, rather than just processing the surface, thereby achieving thorough crushing of the hard and thick branches. The crushing hammer claws are numerous and distributed on the periphery of the crushing roller, so that the hard and thick branches will be subjected to repeated crushing forces from multiple directions after entering the crushing shell. This multi-directional and multi-time crushing action can overcome the hardness and toughness of the hard and thick branches, crush them into smaller particles, and finally achieve the crushing of the hard and thick branches. In summary, the special structure of the crushing roller 203, including the crushing components uniformly distributed and staggered on its periphery, and the crushing hammer claws with curved free ends, coupled with the centrifugal force and impact force generated by high-speed rotation, enables the device to effectively crush hard and thick branches, which not only significantly improves the crushing efficiency and effect of the fruit tree pruning and residual branch crushing and recycling combined operation machine, but also enhances its durability, reduces noise and vibration, and improves operation safety.

[0026] In another technical solution, one side of the pulverizing shell 201 is open, and a removable end cover 212 is provided on the periphery of the opening. A box 213 connected to the end cover 212 is installed on the top of the pulverizing shell 201. The drive motor 205 is accommodated in the box 213, and the rotating shaft of the drive motor 205 is connected to the roller shafts of the feeding roller 202 and the pulverizing roller 203 through a transmission belt. In this technical solution, one side of the pulverizing shell 201 is open and equipped with a removable end cover 212. This design allows the operator to easily access the inside of the pulverizing chamber for daily maintenance and overhaul. Whether it is replacing worn pulverizing parts or cleaning blocked materials, it can be completed quickly and efficiently, thereby ensuring the continuous and stable operation of the operating machine. A box connected to the end cover 212 is installed on the top of the pulverizing shell 201 for accommodating the drive motor 205. This design not only makes the transmission belt connection between the drive motor 205 and the roller shaft of the feed roller 202 and the crushing roller 203 more compact, but also optimizes the overall spatial layout of the operating machine, reduces the occupied space, and makes the structure of the operating machine more compact. The drive motor 205 is cleverly placed in the box and is connected to the roller shaft of the feed roller 202 and the crushing roller 203 through a transmission belt. This connection method not only ensures the stable transmission of power, but also reduces the risk of loosening or damage of the transmission belt caused by vibration and impact. At the same time, the presence of the box 213 also provides certain protection for the drive motor 205, preventing interference and damage from the external environment.

[0027] In another technical solution, a front telescopic plate 214 is slidably mounted on the front end of the collecting platform 206, and a side telescopic plate 215 is slidably mounted on the same side of the front telescopic plate and the collecting platform 206. In this technical solution, the introduction of the front telescopic plate 214 and the side telescopic plate 215 allows the coverage of the collecting platform 206 to be flexibly adjusted according to actual needs, and a transition plate 216 is detachably connected between the front telescopic plate 214 and the side telescopic plate 215.

[0028] In another technical solution, a cab 101 is provided at the top front end of the chassis 106 of the walking locomotive 100, and an engine 102, a hydraulic pump station 103 and a shredded branch collection box 104 are provided at the rear end. The top of the shredded branch collection box is open and is located below the tail end of the delivery pipe 204. In this technical solution, the cab 101 is installed at the front end of the chassis 106 of the walking locomotive 100, which is convenient for driving and pruning. The engine 102 is installed in the engine case 105, and the hydraulic pump station 103 is installed behind the cab 101. The power is provided to the whole machine through the transmission of the engine power, so as to realize the driving and pruning operations of the whole machine. A front axle 107 and a rear axle 108 are provided at the bottom of the chassis 106 of the walking locomotive 100, and tires 109 are installed at both ends of the front axle 107 and the rear axle 108.

[0029] In another technical solution, a plurality of protrusions are evenly distributed on the top of the conveyor belt 207. In this technical solution, the protrusion design on the top of the conveyor belt 207 increases the contact area and friction between the conveyor belt 207 and the material, so that the material can be more stably attached to the conveyor belt 207 during the transmission process, and is not easy to slide or accumulate. This design effectively improves the continuity and stability of material transmission, ensuring that the pruned branches can smoothly and efficiently enter the crushing device 200 for the next step of processing.
