Description

Technical Field

[0001] This utility model relates to the field of cumin harvesting technology, specifically a cumin harvester. Background Technology

[0002] Cotton and cumin intercropping is a highly efficient agricultural planting model. By rationally configuring the growth cycles and spatial requirements of the two crops, the economic benefits of "two harvests from one plot of land" can be achieved. Cumin matures earlier than cotton, and it is necessary to avoid damaging cotton and drip irrigation tape during the cumin harvesting process. Therefore, harvesters are used to harvest cumin. However, existing harvesters still have certain defects in use. Most existing harvesters are tracked and have high requirements for terrain. They cannot work effectively in terraced fields or paddy fields, nor can they effectively process straw.

[0003] Patent CN222128733U discloses a highly efficient cumin harvester that can complete the harvesting, transportation, and collection of cumin in one operation. It is simple to operate, highly automated, and features a traction structure that allows it to connect to a tractor, enabling the tractor to drive the harvester for mobile harvesting. This replaces the existing manual harvesting method, significantly saving manpower and improving harvesting efficiency. By starting a second motor, the first, second, and third pulleys and the belt work together to rotate the first and second conveyor rollers and the rotating shaft simultaneously. This allows the cumin collected by the collection hook to be transported to the collection bin via the conveyor belt. By using a single motor to complete two actions, production costs are greatly reduced.

[0004] In the aforementioned patent, the harvester solves the problems mentioned above. However, the harvester in this patent still has the following problems: during the use of the harvester, cumin needs to be harvested by the harvesting blade. However, the harvesting blade is located at the front of the vehicle body and cannot be adjusted in height. When harvesting cumin intercropped with cotton, the cotton or drip irrigation tape is easily damaged, which can affect the subsequent growth of cotton and seriously reduce the practicality of the harvester.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing harvester structure. Utility Model Content

[0006] The purpose of this utility model is to provide a cumin harvester to solve the problem mentioned in the background art that, during the use of the harvester, cumin needs to be harvested by a harvesting blade, but the harvesting blade is located at the front of the vehicle body and cannot be adjusted in height. When harvesting cumin intercropped with cotton, the cotton or drip irrigation tape is easily damaged, which can affect the subsequent growth of cotton and seriously reduce the practicality of the harvester.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cumin harvester, comprising a tractor body and a mounting plate disposed at the rear end of the tractor body; a material collection frame is disposed on the outer side of the mounting plate, and a hydraulic push rod for driving the material collection frame to discharge material is disposed between the mounting plate and the material collection frame; an inclined conveyor belt is disposed between the tractor body and the mounting plate, and a feeding hydraulic motor is disposed on the outer side of the inclined conveyor belt; a feeding roll frame is disposed at the front end of the mounting frame disposed at the front end of the tractor body, and a horizontal conveyor belt is disposed at the lower end of the mounting frame and the tractor body, and a horizontal hydraulic motor is disposed on the outer side of the horizontal conveyor belt; a cutting table assembly disposed at the feeding end of the horizontal conveyor belt is located at the lower end of the feeding roll frame, and the upper end of the cutting table assembly is fixedly connected to the mounting frame; and a feeding toothed plate is disposed on the outer side of the inclined conveyor belt.

[0008] Preferably, the outer side of the cutting table assembly is provided with two sets of triangular material collectors, and the outer side of the triangular material collectors is rotatably mounted with support wheels to prevent the cutting table assembly from contacting the ground.

[0009] Preferably, the front end of the mounting frame is provided with a front hydraulic lifting rod and a rear hydraulic lifting rod for controlling the lifting and lowering of the cutting table assembly, and the front hydraulic lifting rod is located at the front end of the rear hydraulic lifting rod, and the upper end of the mounting frame is provided with space for the lifting and lowering of the front hydraulic lifting rod.

[0010] Preferably, a drive hydraulic motor is provided on the outer side of the mounting frame, and a transmission sprocket is provided at the output end of the drive hydraulic motor. The driven sprocket rotatably mounted on the outer side of the mounting frame is located at the lower end of the transmission sprocket.

[0011] Preferably, a transmission chain is provided on the outer side of the driven sprocket and the transmission sprocket, and the interior of the driven sprocket is connected to the end of the transmission rod provided at the lower end of the mounting frame, and the rotation of the transmission rod is used to control the cutting table assembly to complete the harvesting of cumin.

[0012] Preferably, a feeding hydraulic motor is provided on the outer side of the mounting frame, and a small sprocket is provided at the output end of the feeding hydraulic motor.

[0013] Preferably, a large sprocket is provided on the outer side of the fixed end of the feed roll frame rotation shaft, and a harvesting chain is provided on the outer side of the large sprocket and the small sprocket, and the radius of the large sprocket is larger than that of the small sprocket to slow down the rotation speed of the feed roll frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting a front hydraulic lifting rod and a rear hydraulic lifting rod at the front end of the mounting frame, the height of the cutting table assembly can be flexibly adjusted. When harvesting cumin intercropped with cotton, the lifting and lowering of the cutting table assembly can be precisely controlled according to the actual position of the cotton and drip irrigation tape, effectively avoiding damage to the cotton or drip irrigation tape, ensuring the subsequent growth of cotton, and greatly improving the practicality of the harvester.

[0015] 2. By setting up a triangular collecting component and rotating and installing support wheels on the outside of the triangular collecting component, the triangular collecting component can initially collect the cumin after cutting, so that the cumin enters the subsequent conveying process in a more concentrated manner. The support wheels can prevent the cutting table assembly from directly contacting the ground, reduce the wear of the cutting table assembly, and ensure the stability of the cutting table assembly during the harvesting process, thereby further improving harvesting efficiency and quality.

[0016] 3. By driving a hydraulic motor to drive a transmission sprocket, which in turn transmits the power to a driven sprocket via a transmission chain, the driven sprocket drives the transmission rod to rotate, thereby controlling the cutting table assembly to complete the harvesting of cumin. This transmission method has a compact structure and high transmission efficiency, which can ensure that the cutting table assembly can complete the harvesting action stably and accurately, thus improving the overall harvesting performance of the harvester.

[0017] 4. The small sprocket is driven by the feeding hydraulic motor, and the small sprocket drives the large sprocket to rotate via the harvesting chain. Since the radius of the large sprocket is larger than that of the small sprocket, it slows down the rotation speed of the feeding roll, which allows the cumin to enter the feeding roll more smoothly and orderly, avoiding spillage or blockage caused by excessive rotation speed, and ensuring the smooth feeding of the harvester.

[0018] 5. Furthermore, the lower end face of the support wheel is set lower than the lower end face of the cutting table assembly. This not only supports the cutting table assembly but also protects it, preventing damage caused by direct contact between the cutting table assembly and the ground in the event of a hydraulic system malfunction.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In a specific embodiment, this utility model provides the following technical solution: a cumin harvester, such as... Figures 1-3 The basic operating process of the cumin harvester is shown in the figure. The tractor body 1 and the mounting plate 2 at the rear end of the tractor body 1 are provided. A material collection frame 3 is provided on the outer side of the mounting plate 2, and a hydraulic push rod 4 for driving the material collection frame 3 to discharge is provided between the mounting plate 2 and the material collection frame 3. An inclined conveyor belt 5 is provided between the tractor body 1 and the mounting plate 2, and a feeding hydraulic motor 6 is provided on the outer side of the inclined conveyor belt 5. A feeding roll frame 10 is provided at the front end of the mounting frame 9 at the front end of the tractor body 1, and a horizontal conveyor belt 7 is provided at the lower end of the mounting frame 9 and the tractor body 1. A horizontal hydraulic motor 8 is provided on the outer side of the horizontal conveyor belt 7. A cutting table assembly 11 is provided at the feeding end of the horizontal conveyor belt 7 at the lower end of the feeding roll frame 10, and the upper end of the cutting table assembly 11 is fixedly connected to the mounting frame 9. A feeding toothed plate 25 is provided on the outer side of the inclined conveyor belt 5.

[0023] When using this cumin harvester, it needs to be driven into the field where cumin and cotton are intercropped to harvest the mature cumin crops. During the process, the cumin is moved to the position of the cutting table assembly 11 by the rotation of the feed reel 10. The cutting blades inside the cutting table assembly 11 cut the cumin crops. After cutting, the cumin crops will move to the upper end of the horizontal conveyor belt 7 by the action of the feed reel 10. At this time, they are transported to the upper end of the inclined conveyor belt 5 by the horizontal conveyor belt 7 and then transported to the inside of the collection frame 3 by the action of the inclined conveyor belt 5. This completes the harvesting and collection process of the cumin crops by the harvester. The expansion movement of the hydraulic push rod 4 can make the collection frame 3 rotate to complete the discharge of the cumin crops inside the collection frame 3, thus facilitating the unified discharge of the cumin harvester.

[0024] In one specific embodiment, such as Figures 1-6 As shown, in order to solve the problem that existing harvesters are prone to damaging cotton seedlings or drip irrigation tapes during operation, the specific harvesting process of this harvester for cumin crops is disclosed. Two sets of triangular material collectors 24 are provided on the outer side of the cutting table assembly 11, and support wheels 12 are rotatably installed on the outer side of the triangular material collectors 24 to prevent the cutting table assembly 11 from contacting the ground. The front end of the mounting frame 9 is provided with a front hydraulic lifting rod 13 and a rear hydraulic lifting rod 14 to control the lifting and lowering of the cutting table assembly 11. The front hydraulic lifting rod 13 is located at the front end of the rear hydraulic lifting rod 14, and the upper end of the mounting frame 9 is provided with space for the lifting and lowering of the front hydraulic lifting rod 13. A drive hydraulic motor 15 is provided on the outer side of the mounting frame 9, and a transmission sprocket 16 is provided at the output end of the drive hydraulic motor 15. A driven sprocket 18 is rotatably installed on the outer side of the mounting frame 9 at the lower end of the transmission sprocket 16.

[0025] When using this cumin harvester, the cutting table assembly 11 needs to be lowered by expanding the front hydraulic lifting rod 13 and the rear hydraulic lifting rod 14. During the movement of the front hydraulic lifting rod 13, its upper end will move inside the slot at the upper end of the mounting frame 9, providing conditions for the extension and retraction of the front hydraulic lifting rod 13 to drive the cutting table assembly 11 to rise and fall. The support wheel 12 on the outside of the cutting table assembly 11 will contact the ground and support the triangular material collection piece 24. The setting of the support wheel 12 can prevent the cutting table assembly 11 from directly contacting the ground and causing damage when the front hydraulic lifting rod 13 and the rear hydraulic lifting rod 14 lose power, thus protecting the cutting table assembly 11. Meanwhile, during the rotation of the feeding frame 10, power is provided by the feeding hydraulic motor 20. The feeding hydraulic motor 20 drives the small sprocket 21 to rotate, which in turn drives the large sprocket 22 to rotate via the harvesting chain 23. This causes the large sprocket 22 to rotate the feeding frame 10, and the cumin is pushed towards the cutting table assembly 11 for cutting using the teeth on the outer side of the feeding frame 10. The larger radius of the large sprocket 22 compared to the small sprocket 21 slows down the rotation speed of the feeding frame 10, preventing the cumin from splashing due to excessive rotation speed. In this case, the cutting table assembly 11 requires power from the hydraulic motor 15 to operate. During operation, the hydraulic motor 15 drives the driven sprocket 18 to rotate via the transmission sprocket 16 and transmission chain 17. The rotation of the driven sprocket 18 then drives the cutting blade inside the cutting table assembly 11 to cut the cumin through the transmission rod 19 (the operation of the cutting table assembly 11 is prior art and will not be elaborated further here), thereby completing the cutting process of the cumin by the harvester and effectively improving the practicality of the harvester.

[0026] Based on the above embodiments, such as Figures 1-6 The specific feeding process of the harvester is shown in the figure. A drive chain 17 is provided on the outer side of the driven sprocket 18 and the drive sprocket 16. The interior of the driven sprocket 18 is connected to the end of the drive rod 19 provided at the lower end of the mounting frame 9. The rotation of the drive rod 19 is used to control the cutting table assembly 11 to complete the harvesting of cumin. A feeding hydraulic motor 20 is provided on the outer side of the mounting frame 9. A small sprocket 21 is provided at the output end of the feeding hydraulic motor 20. A large sprocket 22 is provided on the outer side of the fixed end of the rotating shaft of the feeding roll frame 10. A harvesting chain 23 is provided on the outer side of the large sprocket 22 and the small sprocket 21. The radius of the large sprocket 22 is larger than the radius of the small sprocket 21 to reduce the rotation speed of the feeding roll frame 10.

[0027] When using this cumin harvester, the support wheel 12 needs to roll on the outside of the cotton seedling drip irrigation belt, and the cutting table assembly 11 needs to cut the cumin crop planted in the middle of the drip irrigation belt to avoid damage to the cotton seedling or the drip irrigation belt. The harvested cumin crop will be pushed to the upper end of the horizontal conveyor belt 7 by the action of the feeding roll frame 10. At this time, the horizontal hydraulic motor 8 will provide power for the operation of the horizontal conveyor belt 7 and transport the cumin at the upper end to the lower end of the inclined conveyor belt 5. The feeding tooth plate 25 on the outside of the inclined conveyor belt 5 will transport the cumin crop into the inside of the collection frame 3. During this process, the feeding hydraulic motor 6 needs to provide power for the operation of the inclined conveyor belt 5. This completes the harvesting process of the cumin by the harvester, effectively improving the convenience of the harvester's operation. Furthermore, during the operation of the harvester, a radiator can be installed on the outside of the tractor body 1 to dissipate heat from the internal hydraulic system of the harvester, ensuring the stability of the internal cooling system and increasing the overall practicality.

[0028] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
