Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment technology, specifically to a self-propelled tracked peanut combine harvester. Background Technology

[0002] Peanuts are an important economic crop and oilseed crop in my country, with a wide planting area and the highest output in the world. The efficiency and quality of the harvesting process directly affect the economic benefits of the peanut industry. Traditional peanut harvesting relies on manual or semi-mechanized operations, which are labor-intensive and extremely inefficient.

[0003] With the improvement of agricultural mechanization, peanut combine harvesters are gradually replacing traditional methods. Among them, self-propelled tracked models are favored by farmers due to their advantages such as good adaptability to various soil moisture conditions, ease of operation, and ability to operate in complex fields. They are especially suitable for areas with small plots and steep slopes, such as hilly and mountainous areas in the south, and can make up for the lack of passability of wheeled models. Existing self-propelled peanut combine harvesters usually integrate functions such as digging, conveying, picking, cleaning, and collecting, aiming to achieve the goal of "completing the harvest in one go." However, there are still many technical shortcomings in the connection design and functional adaptation of their core operating modules, which restricts the further improvement of harvesting efficiency and operation quality.

[0004] Regarding module integration and operational coordination, the existing equipment's feeding, conveying, picking, and collection modules are mostly independently designed and simply spliced ​​together, lacking systematic collaborative optimization. The feeding module mostly only undertakes the primary transfer function, and its ability to handle peanut plants with a large amount of soil after digging is insufficient. It fails to provide pretreatment support for the subsequent soil cleaning process during the transfer stage, resulting in a large amount of soil being brought into the conveying module. Although the conveying module has a certain soil cleaning function, its soil cleaning structure design is simple, relying mostly on simple shaking mechanisms. The secondary soil cleaning effect is limited, and the soil is not completely separated from the plant. This not only increases the conveying resistance and easily causes the mechanism to be blocked, but also causes the subsequent picking module to face the problem of soil encasing pods, reducing the picking and separation efficiency, and at the same time aggravating the wear and tear of the picking components. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a self-propelled tracked peanut combine harvester. This harvester utilizes a sequentially connected excavation module, feeding module, conveying module, picking module, and collection module to complete peanut excavation, soil clearing and transfer, secondary soil clearing and conveying, picking and separation, and material collection, forming a complete harvesting operation system.

[0006] To achieve the above objectives, the present invention employs the following technical solution: a self-propelled tracked peanut combine harvester, comprising a walking platform, on which a digging module, a feeding module, a conveying module, a picking module, and a collecting module are sequentially arranged. The digging module is located at the front end of the walking platform and is used to dig peanuts with seedlings from the field and clean the attached soil. The feeding module includes a transfer chamber, in which a conveying auger is installed to transfer peanuts with seedlings to the conveying module. The conveying module is installed on one side of the walking platform and is used to transport peanuts with seedlings to the picking module after secondary soil cleaning. The picking module includes a picking chamber, in which a separating toothed rod is installed. A discharge fence is installed below the picking chamber, and a collecting trough is installed below the discharge fence. The collecting module includes an integrated hopper located above the picking chamber, and a transfer device is provided between the integrated hopper and the collecting trough.

[0007] As a further improvement to the above technical solution: The excavation module includes a mounting frame, a soil-shaking chain is provided in the middle of the mounting frame, an excavation blade is provided at the front end of the soil-shaking chain, and a soil-crushing roller is provided above the soil-shaking chain.

[0008] The number of soil-shaking chains is multiple and they are evenly distributed along the length of the mounting frame. Conveying rods are provided between the multiple soil-shaking chains, and mud-discharging gaps are provided between two adjacent conveying rods.

[0009] One end of the soil-shaking chain is equipped with a drive wheel, and the other end is equipped with a driven wheel. A shaking cam is provided between the drive wheel and the driven wheel.

[0010] The transfer warehouse has an inlet on one side that connects to the fruit picking module and a outlet on the other side. The conveying auger has a telescopic feeding rod inside the end near the outlet.

[0011] The conveying module includes a housing, a conveying chain plate is provided inside the housing, a floating roller is provided inside the conveying chain plate, and a slag discharge hole plate corresponding to the position of the conveying chain plate is provided at the bottom of the housing.

[0012] The conveyor chain includes multiple evenly arranged rake bars, one side of which is provided with a baffle and the other side with a feeding tooth.

[0013] The height of the feeding teeth is greater than the height of the baffle.

[0014] There are two fruit-picking chambers, which are symmetrically distributed to form a U-shaped conveying channel.

[0015] The transfer device includes a positioning frame located above the collection trough, a rotary chain installed on the positioning frame, a plurality of evenly distributed lifting hoppers installed on the rotary chain, a conveyor belt located below the rotary chain on the upper part of the positioning frame, and a recycling hopper located above the collection trough on the lower part.

[0016] The beneficial effects of this invention are as follows: The self-propelled tracked peanut combine harvester includes a walking platform, on which a digging module, a feeding module, a conveying module, a picking module, and a collection module are sequentially arranged. By connecting the digging module, feeding module, conveying module, picking module, and collection module in sequence, the peanut digging, soil clearing and transfer, secondary soil clearing and conveying, picking and separation, and material collection are completed respectively, forming a complete harvesting operation system. The completion of these tasks by a single device can effectively improve work efficiency, save time and labor, and avoid the damage to the field caused by multiple devices operating in the field. At the same time, it can also reduce the initial investment and subsequent maintenance costs of the equipment. The excavation module includes a mounting frame with a soil-shaking chain in the middle. A digging blade is mounted at the front end of the soil-shaking chain, and a soil-crushing roller is located above the chain. As the platform moves forward, the digging blade breaks up the soil to dig up the peanuts. The soil-crushing roller helps to break up large pieces of soil during the transport process, while the soil-shaking chain performs initial soil removal from the surface of the peanuts. This works in conjunction with the secondary soil cleaning in the transfer module to improve the cleanliness of the peanuts, making it easier to harvest and store them later.

[0019] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0020] like Figure 1-9 As shown, the self-propelled tracked peanut combine harvester of this embodiment includes a walking platform 1. The walking platform 1 adopts tracked movement, which can adapt to more complex terrains and can also carry out harvesting operations in humid environments. Along the working process, the walking platform 1 is equipped with a digging module, a feeding module, a conveying module, a picking module and a collecting module in sequence. The excavation module is located at the front of the walking platform 1. Its core function is to dig out peanuts with seedlings from the field and simultaneously clean the soil attached to the peanuts and seedlings. The feeding module, conveying module, picking module, and collection module are connected in sequence to complete the transfer of peanuts, secondary soil cleaning and conveying, picking and separation, and material collection, forming a complete harvesting operation system. Compared with the traditional method of using multiple machines to dig out peanuts from the field and the multi-machine joint operation of picking, harvesting, and storing, the integrated design can complete the peanut digging, picking, harvesting, and storage operations with a single machine, which can effectively improve the operation efficiency, save time and labor, and avoid the crushing damage to the field caused by multiple machines operating in the field. At the same time, using a single machine can also reduce the initial investment and subsequent maintenance costs of the equipment.

[0021] The excavation module includes a mounting frame 9, with a soil-shaking chain 10 in the middle. A digging blade 11 is mounted at the front end of the soil-shaking chain 10. The digging blade 11 is angled to ensure it can cut into the ground to a depth greater than the burial depth of the peanut roots. A soil-crushing roller 12 is positioned above the soil-shaking chain 10. As the platform 1 moves forward, the digging blade 11 breaks the soil and excavates the peanuts. The soil-crushing roller 12 assists in breaking up large pieces of soil during transport, while the soil-shaking chain 10 initially shakes off the soil adhering to the peanut surface. Multiple soil-shaking chains 10 are evenly distributed along the length of the mounting frame 9, providing power and guidance for the rotation of the conveying rod 13, ensuring stable operation of the conveying rod 13 to complete the material transport operation. Conveying rods 13 are connected to the multiple soil-shaking chains 10, with a mud-discharge gap 14 reserved between adjacent conveying rods 13. The distance between adjacent conveying rods 13 is 60-80 mm, facilitating soil detachment from the gap.

[0022] The soil-shaking chain 10 is equipped with a drive module, which includes a drive wheel 15 at one end of the soil-shaking chain 10 and a driven wheel 16 at the other end. The drive wheel 15 and the driven wheel 16 drive the soil-shaking chain 10 to rotate, thereby driving the conveying rod 10 to complete the cyclic rotation and convey the excavated material. A shaking cam 17 is also provided between the drive wheel 15 and the driven wheel 16. Through the cooperation of the drive wheel 15 and the shaking cam 17 when rotating inside the soil-shaking chain 10, the soil-shaking chain 10 can be made to float up and down while rotating, shaking the soil during the material conveying process, thereby improving the soil dropping efficiency.

[0023] The feeding module includes a transfer chamber 2 located inside the conveyor chain 10. The transfer chamber 2 contains a conveyor auger 3. The rotation of the conveyor auger 3 transfers peanuts with seedlings, processed by the digging module, to the conveying module. One side of the transfer chamber 2 has an inlet 18 connected to the picking module, and the other side has a discharge port 19. The end of the conveyor auger 3 near the discharge port 19 is equipped with a telescopic feeding rod 20, which improves the accuracy and stability of the feeding. The telescopic feeding rods 20 are arranged in groups of four, distributed along the circumference of the conveyor auger 3. An installation shaft is located at the connection point of the four telescopic feeding rods 20, with the end of the installation shaft located at the radius of the conveyor auger. When the conveyor auger rotates, the telescopic feeding rod 20 extends a greater length towards the conveyor chain and a shorter length towards the discharge port 19, thus transferring the material to the discharge port 19 during rotation.

[0024] The conveying module is installed on one side of the walking platform 1. It is used to perform secondary soil cleaning on the received peanut seedlings before conveying them to the harvesting module. This module includes a housing 21, inside which is a conveyor chain plate 22. Floating rollers 23 are installed inside the conveyor chain plate 22. A slag discharge hole plate 24 is provided at the bottom of the housing 21 corresponding to the position of the conveyor chain plate 22, through which the soil from the secondary cleaning can be discharged. The conveyor chain plate 22 consists of multiple rotating rake rods 25. One side of the rake rod 25 is equipped with a baffle 26, and the other side is equipped with a material-pushing tooth 27. The height of the material-pushing tooth 27 is greater than the height of the baffle 26, which not only ensures stable material conveying and pushes the material during the conveying process, but also assists in sorting the seedlings in preparation for subsequent harvesting.

[0025] The fruit-picking module includes a fruit-picking chamber 4, inside which is a separating toothed rod 5, and below it is a discharge grate 6. A collection trough 7 is positioned directly below the discharge grate 6. In this embodiment, there are two fruit-picking chambers 4, symmetrically distributed to form a U-shaped conveying channel. This increases the overall travel distance of the material during the fruit-picking stage, thereby achieving the desired fruit-picking rate. Both fruit-picking chambers 4 have spiral guide plates at their upper ends, with opposite conveying directions. This segmented conveying ensures the material reaches the set fruit-picking rate within its travel range, while also preventing excessive entanglement of seedlings that can occur in a single-direction fruit-picking chamber. This reduces machine downtime for maintenance, improves operational efficiency, and reduces the overall size of the equipment, resulting in higher integration and greater flexibility.

[0026] The collection module includes an integrated silo 8 located above the fruit picking chamber 4, and the integrated silo 8 and the collection trough 7 are connected by a transfer device to transfer materials.

[0027] The transfer device includes a positioning frame 28 installed above the collection trough 7, a rotary chain 29 mounted on the positioning frame 28, and multiple lifting hoppers 30 evenly distributed on the rotary chain 29; a conveyor belt 31 located below the rotary chain 29 is provided on the upper part of the positioning frame 28, the feed end of the conveyor belt 31 is located below the running track of the lifting hoppers 30, and the output end extends to the upper part of the integrated silo 8, transferring fresh peanuts into the integrated silo 28 for temporary storage; a recovery hopper 32 is provided at the lower part of the positioning frame 28, facing the collection trough 7, for recovering peanuts that fall from the lifting hoppers 30. Through the cooperation of the lifting hoppers 30, the conveyor belt 31 and the recovery hopper 32, the peanuts in the collection trough 7 can be smoothly transferred to the integrated silo 8, thereby completing the entire peanut harvesting operation.
