Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to an intelligent harvester for underground agricultural products and fruits. Background Art

[0002] In the traditional harvesting process of underground agricultural products, the processing of vines and the collection of fruits often rely on manual operation or simple mechanical assistance. Manual cutting of vines is not only inefficient, but also difficult to ensure the accuracy of cutting, which can easily cause damage to the fruits and consume a lot of manpower costs. For example, when dealing with underground potato crops, farmers need to bend down and cut the vines one by one with a knife, which is labor-intensive and slow. As for the collection of fruits, they are usually dug out with simple digging tools, and then manually sorted and cleaned, which makes the fruit collection process cumbersome and easy to cause fruit omission and damage. In the case of large-scale planting, this traditional method seriously restricts the improvement of agricultural production efficiency and is difficult to meet the needs of the rapid development of modern agriculture.

[0003] Although there are some underground agricultural product harvesters on the market, they still have many defects in function and performance. Some harvesters handle vines in a rough way, simply cutting off the vines and throwing them in the field, which not only affects subsequent farming operations, but also fails to recycle the vines reasonably, resulting in waste of resources and potential environmental pollution. In terms of fruit collection, some harvesters lack effective screening and precise collection devices, resulting in the collected fruits often mixed with a large amount of soil and impurities, increasing the subsequent cleaning costs. At the same time, due to the inability to accurately perceive the location and state of underground fruits, the fruits may be excessively damaged during the excavation process, reducing the quality and commodity value of agricultural products.

[0004] To this end, we proposed an intelligent harvester for underground agricultural products. Summary of the invention

A high-resolution underground imaging radar is integrated at the bottom of the crawler movable frame 1. The underground imaging radar accurately senses the position, shape and size of the fruits of the underground agricultural products, so that the position of the harvesting structure can be adjusted according to the fruits at different depths, thereby improving the collection effect of the underground agricultural products.

[0035] See also Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, specifically, the cutting unit 3 includes a fixed frame 5, a fixed frame 11 and a crushing box 15, the fixed frame 5 is fixedly arranged on the left side of the crawler mobile frame 1, and a winding tooth roller 6 is rotatably arranged on the left side of the fixed frame 5, and a plurality of cutting tooth knives 7 are rotatably arranged on the bottom of the left side of the fixed frame 5, a cutting motor 9 is fixedly arranged inside the fixed frame 5, and a sprocket 8 is fixedly arranged on the bottom end of the output shaft of the cutting motor 9 and the bottom of the plurality of cutting tooth knives 7, and the surfaces of the plurality of sprockets 8 are connected by a chain 10 for transmission; the output shaft of the cutting motor 9 cooperates with the sprocket 8 and the chain 10 to control the rotation of the plurality of cutting tooth knives 7, thereby realizing the cutting process of the connection between the vines and fruits of the underground agricultural products, which is convenient for the subsequent collection of the fruits of the underground agricultural products.

[0036] Furthermore, a fixing frame 11 is fixedly provided on the upper right side of the fixing frame 5, and a feeding conveyor frame 12 is rotatably provided inside the fixing frame 11, a feeding port 13 is provided on the lower left side of the fixing frame 11, and a discharging port 14 is provided on the upper right side of the fixing frame 11, a crushing box 15 is also fixedly provided on the right side of the fixing frame 11, and the interior of the crushing box 15 is connected to the interior of the discharging port 14, two crushing knife rollers 16 are rotatably provided at the lower part of the interior of the crushing box 15, and a crushing gap is left between the two crushing knife rollers 16, discharge frames 17 are fixedly provided on the front and rear sides of the bottom of the crushing box 15, and the interiors of the two discharge frames 17 are connected to the interior of the crushing box 15, the bottom of the inner wall of the crushing box 15 adopts a sloped design with a high middle and low front and rear sides, and a discharge conveyor frame 18 is rotatably provided inside the two discharge frames 17, and the two The discharge conveyor frames 18 are connected to the output shafts of the two drive motors 2 through a belt drive or chain drive structure; specifically, a transmission rod can be set at the driving end of the two discharge conveyor frames 18 through external gear meshing rotation, and then a pulley or sprocket is set at one end of the transmission rod and one end of the output shaft of the drive motor 2, and then a belt or chain is used to connect the two pulleys or sprockets, so that the transmission rod and the output shaft of the drive motor 2 have the same rotation direction. Since the transmission rod and the driving end of the discharge conveyor frame 18 are externally meshed through gears, the rotation direction of the discharge conveyor frame 18 is opposite to the rotation direction of the output shaft of the drive motor 2. When the moving crawler rotates forward, the two discharge conveyor frames 18 rotate in opposite directions; the right sides of the two discharge frames 17 are set to be open.

[0037] It should be noted that when harvesting underground agricultural products and fruits, the vines on the ground are firstly wound by the winding tooth roller 6, and the bottom ends of the vines are cut off by cooperating with a plurality of cutting tooth knives 7 at the bottom of the fixed frame 5, and then the cut vines are sent into the interior of the fixed frame 11 through the feed port 13, and the vines are sent from the interior of the discharge port 14 into the interior of the crushing box 15 by the feeding conveyor frame 12 inside the fixed frame 11, and the vines are crushed by two relatively rotating crushing knife rollers 16 inside the crushing box 15, and the crushed vines slide into the interior of the two discharge racks 17 at the bottom of the crushing box 15, and finally, the crushed vines are discharged into the soil after the harvesting of underground agricultural products and fruits is completed by the discharge conveyor frame 18 inside the two discharge racks 17. This method of crushing and returning vines to the field can increase the organic matter content in the soil, improve soil structure, and improve soil fertility. Compared with the traditional method of centrally cleaning the vines out of the field, it is more conducive to the sustainable development of the agricultural ecosystem and reduces the cost of waste disposal and potential pollution to the environment.

[0038] In a specific embodiment, the present invention uses a winding tooth roller 6 to wind the vines on the ground, which can quickly gather the vines for easy subsequent processing. Driven by the cutting motor 9, a number of cutting tooth knives 7 at the bottom of the fixed frame 5 cooperate with the transmission of the sprocket 8 and the chain 10 to accurately cut the bottom of the vine, greatly improving the efficiency of separating the vines from the fruit. Compared with the traditional manual or simple mechanical cutting method, it is not only faster, but also has a better cutting effect, reducing the risk of damage to the fruit; in addition, the feeding and conveying frame 12 inside the fixed frame 11 transports the cut vines from the feed port 13 to the discharge port 14, and sends them to the crushing box 15, realizing the automation and continuity of the vine processing process, avoiding the tediousness and inefficiency of manual handling, and further improving the overall operating efficiency, making the preparatory work for the harvest of underground agricultural products smoother and more efficient;

[0039] The two crushing rollers 16 inside the crushing box 15 rotate relative to each other to crush the vines. This crushing method can crush the vines into small fragments, making them easier to decompose in the soil and be used by microorganisms, thereby increasing the organic matter content in the soil more quickly, improving the soil structure, and creating more favorable soil conditions for subsequent agricultural production; the bottom of the inner wall of the crushing box 15 adopts a slope design with a high middle and low front and back sides, so that the crushed vines can slide smoothly into the two discharge racks 17, and then the discharge conveyor rack 18 linked to the drive motor 2 discharges the crushed vines into the soil where the fruit has been harvested, realizing the vines crushed in situ and returned to the field. This process is not only environmentally friendly and reduces the transportation and treatment costs of waste, but also has positive significance for the sustainable development of the agricultural ecosystem and helps to maintain the fertility and ecological balance of the soil.

[0044] It should be noted that when controlling the synchronous transmission drive of the coiling gear roller 6, the feeding conveyor frame 12 and the crushing knife roller 16 in the cutting unit 3, the output shaft of the servo motor 20 is used to control the driving shaft 21 to rotate, and the feeding conveyor frame 12 is driven to rotate by the driving shaft 21. At the same time, the driving gear 22 and the driven gear 23 arranged on the surface of the driving shaft 21 are engaged and driven, thereby driving the driven shaft 24 to rotate synchronously, and then driving the transmission shaft 25 to rotate through two pulleys 26, and the transmission shaft 25 drives the coiling gear roller 6 to rotate synchronously;

[0045] In addition, since the surface of the driving gear 22 is also meshed with the surface of the driven gear 27, the driven shaft 2 39 is driven to rotate synchronously, and the coordinated transmission of the two pulleys 29 allows the crushing roller 16 on the left to rotate synchronously. Finally, two mutually meshing transmission gears 28 are used to allow the crushing roller 16 on the right and the crushing roller 16 on the left to rotate synchronously in opposite directions, thereby realizing continuous crushing of the vines inside the crushing box 15.

[0046] Embodiment 3:

[0047] See also Figure 2 , Figure 7 and Figure 8As shown, specifically, the material receiving unit 4 includes a screening frame 34 and a material receiving drum 36, the screening frame 34 is fixedly arranged on the right side inside the crawler-type moving frame 1, the fixed frame 2 32 is fixedly arranged on the left side of the screening frame 34, and the bottom of the fixed frame 2 32 extends to the bottom of the crawler-type moving frame 1, and the fixed frame 2 32 is also rotatably arranged inside the fixed frame 2 32, and the upper right side of the fixed frame 2 32 is connected to the inside of the screening frame 34, and the rotating frame 30 is also rotatably arranged at the bottom of the screening frame 34 and located on the right side of the fixed frame 2 32, and the bottom of the rotating frame 30 is fixedly arranged with a plow 31; when harvesting the underground agricultural products and fruits, the working position of the plow 31 is first adjusted by the rotating frame 30, and the underground agricultural products and fruits are dug out by the plow 31, and the dug out fruits are sent to the inside of the screening frame 34 in cooperation with the material receiving conveying frame 33 inside the fixed frame 2 32;

[0048] Furthermore, a collecting barrel 36 is fixedly provided on the right side of the top of the screening frame 34, and a vibrating screen 35 is fixedly provided at the bottom of the screening frame 34 and directly below the collecting barrel 36, wherein the bottom of the vibrating screen 35 extends to the bottom of the crawler-type mobile frame 1, and one side of the vibrating screen 35 generates a vibration force through a vibration motor, and the vibrating screen 35 is used to vibrate and screen the soil on the surface of the fruit, and an air blowing head can also be provided at the bottom of the left side of the collecting barrel 36 to assist the vibrating screen 35 in improving the removal efficiency of the soil on the surface of the fruit; a storage barrel 37 is fixedly provided inside the collecting barrel 36, and the storage barrel 37 is fixedly provided with a storage barrel 37. A rotating material receiving rack 38 is also rotatably arranged on the surface of 7, and an opening is arranged on the top of the material storage barrel 37, and the side of the rotating material receiving rack 38 is in sliding contact with the inner wall of the material storage barrel 36; wherein, the rotating material receiving rack 38 is driven to rotate by a motor fixedly arranged on the front side of the material storage barrel 36, and the middle of the rotating material receiving rack 38 adopts a hollow design, and a plurality of plates on the rotating material receiving rack 38 are used to push the fruits on the vibrating screen 35 into the interior of the material storage barrel 36. When the fruits move to the top of the material storage barrel 37 with the rotation of the rotating material receiving rack 38, the fruits are automatically collected through the opening arranged on the top of the material storage barrel 37.

[0049] It should be noted that when harvesting underground agricultural products and fruits, the underground agricultural products and fruits are dug out by the plow 31, and the agricultural products and fruits are sent to the inside of the screening frame 34 by cooperating with the material collection and conveying frame 33 inside the fixed frame 2 32. The soil attached to the surface of the fruit is automatically screened out by the vibrating screen 35 inside the screening frame 34, and finally the fruit after the surface soil is screened out is sent to the inside of the storage barrel 37 by the rotating rotating material collection frame 38 for automatic collection.

[0050] In a specific embodiment, the present invention uses the servo motor 20 on the drive frame 19 as the core power source to achieve synchronous transmission drive of the coiling gear roller 6, the feeding conveyor frame 12 and the crushing knife roller 16. Compared with the decentralized drive, this centralized drive mode reduces the links and energy loss of power transmission, improves the transmission efficiency and accuracy, and the output shaft of the servo motor 20 drives the driving shaft 21 to rotate. The driving shaft 21 is directly connected to the feeding conveyor frame 12 to ensure the stability and accuracy of feeding. Through a series of gear meshing and belt transmission, such as the meshing of the driving gear 22 with the driven gear 1 23 and the driven gear 2 27, and the belt transmission of the pulley 1 26 and the pulley 2 29, the power is cleverly distributed to the coiling gear roller 6 and the crushing knife roller 16, so that the rotation speed and action between the various components can be accurately coordinated, ensuring the continuity and efficiency of the vine processing process, avoiding the jamming or operation interruption caused by the asynchronous transmission, and greatly improving the work efficiency and quality of the underground agricultural product vine processing;

[0051] The material collection and conveying frame 33 extending from the bottom of the fixed frame 32 to the bottom of the crawler-type mobile frame 1 can quickly transport the fruits to the screening frame 34 after the rake 31 has dug them out, thereby reducing the residence time of the fruits on the ground and reducing the risk of damage and loss of the fruits. Secondly, the vibrating screen 35 at the bottom of the screening frame 34 can effectively screen out the soil attached to the surface of the fruits, improve the purity of the fruits, and facilitate subsequent storage and processing. For example, the vibration of the vibrating screen 35 can cause soil particles to fall through the pores of the screen, while the fruits remain on the screen waiting for further collection. Finally, the rotating material collection frame 38 in the material collection barrel 36 is driven by a motor to accurately push the fruits on the screen into the storage barrel 37 for automatic collection. This automated collection method not only improves the collection efficiency, but also reduces the labor intensity and labor cost of manual operation, making the entire fruit collection process smoother, more efficient and intelligent, ensuring that underground agricultural products can be collected quickly and completely, and improving the harvest efficiency of agricultural production;

[0052] Finally, by closely combining the cutting unit 3 and the collecting unit 4 with the crawler mobile frame 1, a highly coordinated operation system is formed. While the cutting unit 3 processes the vines, the collecting unit 4 can timely dig out, convey, screen and collect the underground fruits. The actions of each component cooperate with each other and do not interfere with each other. In the process of the crawler mobile frame 1 moving forward, the plow 31, the collecting and conveying frame 33, the vibrating screen 35 and the rotating collecting frame 38 and other components work in sequence according to a predetermined program, realizing the integrated operation of underground agricultural products from vine cleaning to fruit collection, which not only improves the overall working efficiency of the harvester, but also reduces the operating time and energy consumption, so that the harvester can complete more harvesting tasks in a limited time, adapt to the needs of large-scale and high-efficiency production in modern agriculture, provide strong support for the mechanization and intelligent development of agricultural production, and improve the comprehensive benefits and competitiveness of agricultural production.

[0055] When harvesting underground agricultural products and fruits, firstly, the vines on the ground are wound by the winding tooth roller 6, and the bottom ends of the vines are cut off by the several cutting tooth knives 7 at the bottom of the fixed frame 5, and then the cut vines are sent into the interior of the fixed frame 11 through the feed port 13, and the vines are sent from the interior of the discharge port 14 into the interior of the crushing box 15 by the feeding conveyor frame 12 inside the fixed frame 11, and the vines are crushed by two relatively rotating crushing knife rollers 16 inside the crushing box 15, and the crushed vines slide into the interior of two discharge racks 17 at the bottom of the crushing box 15, and finally the crushed vines are discharged into the soil by the discharge conveyor frame 18 inside the two discharge racks 17 to complete the harvesting of underground agricultural products and fruits;

[0056] When controlling the synchronous transmission drive of the coiling gear roller 6, the feeding conveyor frame 12 and the crushing knife roller 16 in the cutting unit 3, the output shaft of the servo motor 20 is used to control the driving shaft 21 to rotate, and the feeding conveyor frame 12 is driven to rotate by the driving shaft 21. At the same time, due to the meshing transmission of the driving gear 22 and the driven gear 1 23 provided on the surface of the driving shaft 21, the driven shaft 1 24 is driven to rotate synchronously, and then the transmission shaft 25 is driven to rotate through two pulleys 1 26, and the transmission shaft 25 is used to drive the coiling gear roller 6 to rotate synchronously;

[0057] In addition, since the surface of the driving gear 22 is also meshed with the surface of the driven gear 27, the driven shaft 2 39 is driven to rotate synchronously, and the two pulleys 29 are used to cooperate with each other to allow the crushing roller 16 on the left to rotate synchronously. Finally, the two mutually meshing transmission gears 28 are used to allow the crushing roller 16 on the right and the crushing roller 16 on the left to rotate synchronously in opposite directions, thereby realizing continuous crushing of the vines inside the crushing box 15.

[0058] The agricultural products and fruits under the ground are dug out by the plow 31, and the agricultural products and fruits are sent to the inside of the screening frame 34 in cooperation with the material collecting and conveying frame 33 inside the fixed frame 2. The soil attached to the surface of the fruits is automatically screened out by the vibrating screen 35 inside the screening frame 34, and finally the fruits after the surface soil is screened out are sent to the inside of the storage barrel 37 for automatic collection by the rotating material collecting frame 38.
