A self-propelled potato planter

Abstract

The present invention discloses a self-propelled potato planter, comprising: a device support, an engine mounted on the top of the device support, and a gear reduction box mounted on the engine. The self-propelled potato planter provided by the present invention places potatoes of different sizes in a large seed box, places potatoes of similar target sowing size in a small seed box, rotates an inner gear ring, and drives an adjustment plate to slide inside a restriction shell, thereby adjusting the size of the space at the bottom of the seed scoop, so that relatively small potatoes can pass through the seed scoop without being sown, while relatively large potatoes can be passed for sowing. Subsequently, the empty seed scoops will be replanted by a replanting mechanism, ultimately achieving a moderate size of potato sowing in the same area. Since potatoes of similar size have similar growth requirements and development processes, subsequent fertilization, irrigation, and pest and disease management of the potatoes are more effective, thereby improving the final potato yield.

Description

Technical Field

[0001] The present invention relates to the technical field of sowing, in particular to a self-propelled potato seeder. Background Art

[0002] Potato sowing involves placing potato tubers or seeds into the soil to grow into new plants. The size of the potato seeds at the time of sowing significantly affects the final harvest. Larger seeds typically contain more nutrients, germinate faster, and establish a strong root system, which promotes higher yields and larger tubers. Smaller seeds, on the other hand, may require more time and energy to germinate and grow. While their yield may be lower, a good harvest can still be achieved with proper management, such as optimizing soil conditions and fertilization. Therefore, selecting the appropriate seed size and implementing effective sowing management are important factors in optimizing potato harvests.

[0003] For example, a Chinese invention patent (CN115104389B) discloses a self-propelled potato micro-tuber seeder, which records: "Pour disordered micro-tuber into the seed sorting cone, and through the combined action of the conical turntable and the seed thinning device, the disordered micro-tuber is orderly transported to the seeding trough. After the micro-seeds in the seeding trough reach the seeding port, they fall into the groove of the transmission belt that moves synchronously with the seeding trough. The conveyor belt transports the micro-tuber to the end of the conveyor belt and then falls, completing the seeding. The conveyor belt and the conical turntable have the same linear speed to achieve precise seeding." It also records: "During sowing, there is still manual seeding and semi-automatic planting, and many areas still use manual planting. It is difficult to ensure the agronomic requirements of uniform plant spacing and uniform sowing depth, consumes a lot of manpower, and the working efficiency is low, which is far from meeting the requirements of potato mechanization development." Technical problems.

[0004] To sum up the above, it can be seen that the existing technology uses the method of transporting disordered micro potatoes to the seeding trough in an orderly manner, and the conveyor belt transports the micro potatoes to the end of the conveyor belt and then drops them to complete the seeding. However, this method has the following technical problems: the device cannot screen the potatoes according to their size during the sowing process, which may cause potatoes of different sizes to be cross-sown in the same piece of land, resulting in uneven growth of potatoes, affecting the uniformity and efficiency of the overall harvest. For this reason, the present application proposes a self-propelled potato planter to provide a new technical solution to solve the technical problems mentioned in the above patents. Summary of the Invention

[0005] Based on this, it is necessary to provide a self-propelled potato planter to address the above technical problems. By placing potatoes of different sizes in a large seed box, placing potatoes of similar target sowing size in a small seed box, and rotating the inner gear ring, the first bevel gear can be rotated under the transmission of the corresponding driven gear, and then the inner thread shell is driven to rotate through the second bevel gear, and then the second threaded rod is moved under the restriction of the restriction shell and the adjustment plate, and finally the adjustment plate is driven to slide inside the restriction shell, thereby adjusting the size of the space at the bottom of the seed spoon, so that relatively small potatoes can be planted. Potatoes that pass through the seed scoop will not be sown, while relatively large ones can be passed for sowing. The empty seed scoops will be replanted by the replanting mechanism later, and finally the potato sowing size in the same area will be moderate, so that the operator can carry out unified fertilization, irrigation and pest and disease management during the subsequent potato growth process. Moreover, since the growth requirements and development processes of potatoes of similar sizes are relatively similar, the subsequent fertilization, irrigation and pest and disease management of potatoes are more effective, thereby improving the final potato harvest. Moreover, the operation is simple and convenient, which reduces the workload of potato sorting and is easy to promote.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

During sowing, relatively large potatoes can be passed on for sowing, and the empty seed spoons will be replanted by the replanting mechanism, ultimately achieving moderate potato sowing size in the same area, so that the operator can carry out unified fertilization, irrigation and pest and disease management during the subsequent potato growth process.

Moreover, the operation is simple and convenient, which reduces the workload of potato sorting and facilitates promotion.

[0022] The self-propelled potato planter provided by the present invention can load and sow potatoes by controlling an active motor, and can also drive the third rotating rod to rotate accordingly through the fifth sprocket and the sixth sprocket, thereby driving the metering wheel to rotate accordingly, thereby performing quantitative fertilization while sowing the potatoes. Compared with sowing and fertilizing separately, the operator's labor is reduced, and sowing and fertilizing are performed simultaneously, which greatly improves the potato sowing efficiency of the device. Moreover, quantitative fertilization is performed along with the potato sowing operation, so that the fertilizer can be evenly distributed in the sowing area, avoiding the problem of uneven fertilization, and improving the practicality of the device.

[0023] The self-propelled potato planter provided by the present invention can identify whether there are potatoes inside the seed scoop at the corresponding position through a sensor, and can transmit the identification result to the controller. If there are no potatoes inside the seed scoop, the first electric telescopic rod can be controlled to open the corresponding rotating cover, and then potatoes of appropriate size can be put in to make up for the missing potatoes in the seed scoop. After releasing a potato, the controller controls the first electric telescopic rod to close the rotating cover and replant the empty seed scoop, thereby improving the uniformity of potato sowing, thereby reducing the waste of land and subsequent fertilizer application and other resources, ensuring the density of potato growth, and thus improving the economic benefits of potato planting.

[0024] The self-propelled potato planter provided by the present invention can adaptively adjust the position of the movable frame through the second electric push rod and the movable frame, and relies on the first trenching member and the second trenching member to trench the ground for the convenience of sowing and fertilizing potatoes, and then relies on the design of the pointed surfaces of the first trenching member and the second trenching member to cover the soil. In this process, fertilizer is applied inside the soil, which can effectively reduce fertilizer loss compared to the soil surface where fertilizer is applied, thereby improving fertilizer utilization rate, and relies on the U-shaped frame, the support screw and the film roller to perform subsequent film covering work, thereby increasing the functionality of the device, and before film covering, the third threaded rod can be rotated to drive the pressing wheel to descend, so that the pressing wheel presses the film into the soil, avoiding the situation where the film is blown up due to wind after film covering, and avoiding the need for manual shoveling of soil after film covering to press the soil on the film to ensure the stability of the film, thereby improving the stability of the film covering, reducing manpower consumption, and improving the practicality of the device.

[0025] The self-propelled potato planter provided by the present invention can adjust the position of the adjusting wheel by rotating the first threaded rod, thereby making the crawler track loose or stably supported, thereby facilitating the disassembly and installation of the crawler track, facilitating subsequent maintenance of the device, and improving the practicality of the device.

[0043] In order to solve this technical problem, the present invention provides a self-propelled potato planter, which is used for potato planting.

[0044] Specifically, please refer to Figure 1-Figure 3, the self-propelled potato planter specifically includes:

The left and right sides of the device bracket 1 are respectively provided with a moving mechanism 7, a sowing mechanism 8 is provided on the device bracket 1, a fertilizing mechanism 9 is provided on the device bracket 1, a reseeding mechanism 10 is provided on the sowing mechanism 8, and a furrowing and film covering mechanism 11 is provided on the device bracket 1;

[0047] The self-propelled potato planter provided by the present invention places potatoes of different sizes in the large seed box 19, places potatoes of similar target seeding size in the small seed box 50, and rotates the inner gear ring 35. The first bevel gear 37 rotates accordingly under the transmission of the corresponding driven gear 36, and then drives the internal thread shell 38 to rotate accordingly through the second bevel gear 39, and then the second threaded rod 40 moves accordingly under the restriction of the limiting shell 41 and the adjusting plate 42, and finally drives the adjusting plate 42 to slide inside the limiting shell 41, thereby adjusting the size of the bottom space of the seed spoon 31, so that the relatively small soil Beans can pass through the seed scoop 31 without being sown, while relatively large ones can be passed for sowing. The empty seed scoops 31 will be replanted by the replanting mechanism 10 later, and finally the potato sowing size in the same area is moderate, so that the operator can carry out unified fertilization, irrigation and pest and disease management during the subsequent potato growth process. Moreover, since the growth requirements and development processes of potatoes of similar size are relatively similar, the subsequent fertilization, irrigation and pest and disease management of potatoes are more effective, thereby improving the final potato yield. Moreover, the operation is simple and convenient, which reduces the workload of potato sorting and is easy to promote.

[0048] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0049] Example 1:

[0050] Please refer to Figure 2-Figure 8 , a self-propelled potato planter comprising:

[0051] The driving assembly includes an active motor 22 and a mounting chain 28. The outer wall of the device bracket 1 is fixedly mounted with the active motor 22. The bottom of the device bracket 1 is rotatably connected to the first rotating rod 23. The output end of the active motor 22 is fixedly connected to the first sprocket 24. The outer wall of the first rotating rod 23 is fixedly connected to the second sprocket 25. The outer wall of the first sprocket 24 and the outer wall of the second sprocket 25 are connected by a chain transmission. The outer wall of the mounting plate 21 is rotatably connected to the second rotating rod 26. The outer wall of the second rotating rod 26 is fixedly connected to the third sprocket 27 on both sides of the middle. The outer wall of the rod 23 is fixedly connected to the fourth sprocket 29 on the left and right sides of the second sprocket 25, and the outer wall of the third sprocket 27 is connected to the outer wall of the fourth sprocket 29 through the installation chain 28. It can be seen that the control active motor 22 drives the first sprocket 24 to rotate accordingly, and then drives the second sprocket 25 to rotate through the corresponding chain, and at the same time makes the first rotating rod 23 rotate. The rotation of the first rotating rod 23 can drive the two fourth sprockets 29 to rotate accordingly, and then drives the third sprocket 27 to rotate through the corresponding installation chain 28, and then drives the second rotating rod 26 to rotate.

[0052] The rotating assembly includes a mounting frame 30, the outer wall of the mounting chain 28 is detachably connected to the mounting frame 30 by bolts, the inner wall of the mounting frame 30 is fixedly connected to the seed spoon 31, the outer wall of the seed spoon 31 is fixedly connected to the support shell 32, the outer wall of the support shell 32 is fixedly connected to the protective shell 33, the protective shell 33 can protect the internal threaded shell 38 to prevent the internal threaded shell 38 from being squeezed or hit by potatoes and causing deformation, thereby ensuring the service life of the device, the inner wall of the support shell 32 is rotatably connected to the rotating shaft 34, the inner wall of the support shell 32 is rotatably connected to the inner ring gear 35, the outer wall of the inner ring gear 35 is provided with anti-slip grooves, the outer wall of the rotating shaft 34 is fixedly connected to the driven gear 36, the driven gear 36 is meshed with the outer wall of the inner ring gear 35, and the bottom end of the rotating shaft 34 is fixedly connected to the first bevel gear 37. It can be seen that the rotating inner ring gear 35 can drive the corresponding rotating shaft 34 to rotate through the driven gear 36, and then drive the corresponding first bevel gear 37 to rotate.

[0053] The adjusting assembly includes an internal threaded shell 38, the inner wall of the supporting shell 32 is rotatably connected to the internal threaded shell 38, the internal threaded shell 38 is rotatably connected to the inner wall of the protective shell 33, the outer wall of the internal threaded shell 38 is fixedly connected to the second bevel gear 39, the second bevel gear 39 is meshed with the outer wall of the first bevel gear 37, the inner wall of the internal threaded shell 38 is threadedly connected to the second threaded rod 40, the inner wall of the seed spoon 31 is fixedly connected to the limiting shell 41, the inner wall of the limiting shell 41 is slidably connected to the adjusting plate 42, and the second threaded rod 40 is fixedly connected to the outer wall of the adjusting plate 42.

[0054] The fertilizing mechanism 9 includes a fertilizer box 43, the top of the device bracket 1 is fixedly connected to the fertilizer box 43, one end of the second rotating rod 26 is fixedly connected to the fifth sprocket 44, the inner wall of the fertilizer box 43 is rotatably connected to the third rotating rod 45, the outer wall of the third rotating rod 45 is fixedly connected to the sixth sprocket 46, the fifth sprocket 44 and the sixth sprocket 46 are connected by a chain transmission, the bottom of the fertilizer box 43 is fixedly connected to the fertilizer discharge pipe 48, the outer wall of the third rotating rod 45 and the inner part of the fertilizer discharge pipe 48 are fixedly connected to the metering wheel 47. It can be seen that the rotation of the second rotating rod 26 drives the fifth sprocket 44 to rotate accordingly, and then drives the sixth sprocket 46 to rotate accordingly through the corresponding chain, and at the same time makes the third rotating rod 45 rotate accordingly, and the third rotating rod 45 drives the metering wheel 47 to rotate accordingly, so that the fertilizer inside the fertilizer box 43 enters the fertilizer discharge pipe 48 and then moves downward inside the fertilizer discharge pipe 48 through the rotation of the metering wheel 47.

[0055] Through the above-mentioned structural design, by placing potatoes of different sizes in the large seed box 19, and placing potatoes of a size similar to that to be sown this time in the small seed box 50, the inner gear ring 35 is rotated to make the adjustment plate 42 slide inside the limiting shell 41, and after adjusting the position of the adjustment plate 42 in the limiting shell 41 to a suitable position, potatoes smaller than those to be sown this time can pass through the seed spoon 31, and then the active motor 22 is controlled to drive the mounting chain 28 to move, and the multiple seed spoons 31 can be used to transport suitable potatoes to the discharge pipe 20 for sowing, and then the third rotating rod 45 is driven to rotate, so that the fertilizer inside the fertilizer box 43 flows out from the fertilizer discharge pipe 48 in a quantitative manner for fertilization.

During this process, the spring 59 is stretched, and then a potato in the small seed box 50 can be placed into the discharge pipe 20, and then the first electric telescopic rod 55 is controlled to drive the rotating cover 58 to cover the fixed tube 52 through the first connecting rod 56 and the second connecting rod 57 to prevent the potato from falling.

Subsequently, the first trenching member 66 and the second trenching member 67 are used to open trenches on the ground. The design of the pointed surface of the groove member 67 allows for subsequent covering with soil. When film covering operations are required later, the nut on one side of the support screw 69 can be unscrewed, and then the support screw 69 can be removed, and the film roller 70 can be placed in a suitable position on the U-shaped frame 68, so that the support screw 69 can be inserted into the U-shaped frame 68 and pass through the film roller 70, and then the corresponding nut can be screwed on.
