The bracket and the walking surface are made of stainless steel, which is sturdy and durable. The main parts are fixed with stainless steel screws, which are convenient for disassembly and repair and replacement. The seed selector is replaceable and suitable for planting particles of various sizes. With the transparent cochlear funnel observation window and the seed storage bin installed with single-sided transparent tempered glass, the amount of corn and the seed selection in the seed storage bin can be observed at any time to ensure the quality of sowing. A bracket adjustment plate with three holes is installed, and the corresponding hole positions are selected according to the different heights and requirements of the operator to adjust the height of the handle.

By operating the slope loosening structure 5, the loosening of the slope ground is achieved while slowing down the going downhill of the personnel, which improves the performance of the corn planter on the slope ground to a certain extent. By operating the pulling structure 6, the flexible pulling of the push plate frame 504 is facilitated, which not only facilitates the later stacking and unloading of materials, but also ensures the rebounding and resetting of the first spring 509. By operating the auxiliary structure 7, while achieving deep loosening of the ground soil, it facilitates the cleaning of the surface of the loosening block 514, which further improves the use effect of the slope loosening structure 5.

[0043] The specific settings and functions of the slope loosening structure 5, the pulling structure 6 and the auxiliary structure 7 are described in detail below.

[0044] Reference Figure 1-Figure 6As shown, in this embodiment: the internal thread of the fixed plate 510 is penetrated with a bolt 512, and the lower end of the bolt 512 is fixedly connected to the rectangular plate 513. By rotating the bolt 512, the fine adjustment of the depth of the loosening block 514 into the ground can be achieved, which further improves the loosening effect on the slope ground in the later stage. The surface of the limit frame 501 is sleeved with a first spring 509, and the two ends of the first spring 509 are respectively fixedly connected to the connecting plate 502 and the fixed plate 510. In the process of going uphill, the corn seeds will tend to approach one side of the push frame 1 due to their own gravity. At this time, the push plate will reset, and the fixed plate 510 will be lifted by the elastic force of the first spring 509, reducing the resistance of the personnel when going uphill, and facilitating the climbing work of the personnel returning. The surface of the limit frame 501 is rotatably connected with the limit wheel 503, and the side wall of the storage box 4 is fixedly connected with a fixed rod 507, and the surface of the fixed rod 507 is rotatably connected with a support bar 508. When it is necessary to work on a flat ground, the limit frame 501 can be pulled to lift the loose soil block 514 together, and the support bar 508 can be stuck on the lower side of the limit frame 501. At this time, the support work of the limit frame 501 and the loose soil block 514 after lifting can be achieved, which facilitates the normal pushing work of the push frame 1 on the flat ground.

[0045] Reference Figure 1-Figure 3 and Figure 5 as well as Figure 7-Figure 8 As shown, in this embodiment: the pulling structure 6 also includes a limit ring 65 slidably connected to the surface of the push frame 1, and the side wall of the limit ring 65 is fixedly connected with a pull rod 67, and the pull rod 67 is fixedly connected to the other end of the pull rope 61. When starting to work uphill, the pull rope 61 is driven to move, and the pulling work of the push plate frame 504 can be realized at this time, which is convenient for the accumulation of materials inside the storage box 4. By accumulating the bottom material, it is convenient for the subsequent collection and unloading of corn kernels, and it is convenient for the accumulation of corn kernels, thereby facilitating the reset and lifting work of the first spring 509 to pull up the fixed plate 510. A round rod 63 is fixedly connected to the surface of the push frame 1, and a pulley 62 is rotatably connected to the side wall of the round rod 63. A stop rod 64 is fixedly connected to the side wall of the connecting rod 505, and the pull rope 61 is located between the pulley 62 and the stop rod 64. The sliding of the pull rope 61 on the surface of the pulley 62 plays a role in changing the direction of the pulling force of the pull rope 61, and the setting of the blocking rod 64 facilitates the encirclement of the pull rope 61 and prevents the pull rope 61 from being staggered from the pulley 62. The blocking rod 64 is a "U"-shaped structure, and a blocking ring 66 is fixedly connected to the side wall of the push frame 1. By setting the blocking ring 66, it is avoided that the limiting ring 65 slides to the side away from the handle of the push frame 1, which makes it inconvenient for personnel to operate the pull rod 67.

[0046] Reference Figure 1-Figure 3 and Figure 6 as well as Fig. 9As shown, in this embodiment: the side wall of the rectangular frame 71 is fixedly connected with a bar 74, and the side wall of the bar 74 is evenly rotated and connected with a plurality of grab hooks 72. After the ground is loosened by the loosening block 514, the arranged grab hooks 72 can realize further crushing work after the preliminary loosening of the ground. The grab hook 72 is a "J" type structure, and the end side of the grab hook 72 is a tip structure. Due to the unevenness of the ground, the grab hook 72 can realize the movement of the bar 74 and the rectangular frame 71 in the process of grabbing the ground soil. The upper surface of the positioning block 75 is fixedly connected with a second spring 77, and the other end of the second spring 77 is fixedly connected to the positioning rod 76. By setting the second spring 77, the pop-up reset work of the rectangular frame 71 on the later positioning rod 76 can be realized, and the shaking frequency of the rectangular frame 71 is improved.

[0047] Detailed description of usage: After corn seeds are loaded into the storage box 4, when downhill work is required, the corn will tend to move against one side of the push plate frame 504 due to the gravity of the slope position. At this time, the push plate frame 504 will drive the push block 506 on the connecting rod 505 to move, and the inclined surface of the push block 506 will squeeze the limit frame 501 to move downward. The loosening block 514 on the rectangular plate 513 will move downward with the limit frame 501 at this time, and the push block 506 slides on the surface of the limit wheel 503 to reduce the space between the push block 506 and the limit frame 501. The friction force improves the downward pressure effect on the limit frame 501, and the loosening block 514 will penetrate into the muddy ground. By turning the bolt 512, the depth of the loosening block 514 penetrating into the ground can be fine-tuned, further improving the loosening effect on the slope ground in the later stage. In the process of pushing the push frame 1 downhill, firstly, the loosening block 514 can be used to flexibly loosen the ground, and the loosening block 514 is indirectly pressed by the pressure of the corn seeds, further improving the loosening efficiency of the slope ground. Secondly, after the loosening block 514 penetrates into the ground, , which increases the resistance of the push frame 1 when it goes downhill, and due to inertia, the more seeds there are in the storage box 4, the greater the pressure on the loose soil block 514 to penetrate into the ground. The resistance during the pushing process of the push frame 1 can be flexibly adjusted according to the seed situation, avoiding the situation where people rush down the slope due to inertia, and improving the safety during the sowing process. In the process of going uphill, the corn seeds will tend to move closer to one side of the push frame 1 due to their own gravity. At this time, the push plate will reset, and the fixed plate 510 will be lifted up by the elastic force of the first spring 509, reducing the number of people going uphill. The resistance during climbing is convenient for the personnel to return. When it is necessary to work on the flat ground, the limit frame 501 can be pulled to lift the loosening block 514 together, and the support bar 508 can be stuck on the lower side of the limit frame 501. At this time, the support work of the limit frame 501 and the loosening block 514 after lifting can be achieved, which is convenient for the normal flat pushing work of the push frame 1 on some flat ground. By operating the slope loosening structure 5, the loosening work on the slope ground is achieved while slowing down the descent of the personnel, thereby improving the performance of the corn planter on the slope ground to a certain extent.

[0048] When starting to work uphill, the pull rod 67 can be held by hand, and the pull rod 67 will drive the pull rope 61 to move. At this time, the pulling work of the push plate frame 504 can be realized, which is convenient for the accumulation of materials inside the storage box 4. By accumulating the materials at the bottom, it is convenient for the subsequent collection and unloading of corn kernels, and secondly, it is convenient for the accumulation of corn kernels, thereby facilitating the reset and lifting of the fixing plate 510 by the first spring 509. In the process of pulling the pull rope 61, the pull rope 61 slides on the surface of the pulley 62. By changing the direction of the pulling force of the pull rope 61, the setting of the blocking rod 64 facilitates the encirclement of the pull rope 61 and avoids the pull rope 61 from being offset from the pulley 62. By setting the blocking ring 66, it is avoided that the limiting ring 65 slides to the side away from the handle of the push frame 1, which makes it inconvenient for personnel to operate the pull rod 67. Through the operation of the pulling structure 6, the flexible pulling work of the push plate frame 504 is facilitated, which not only facilitates the later stacking and unloading of materials, but also ensures the rebound and reset work of the first spring 509.

[0049] During the downhill process, after loosening the ground with the loosening block 514, the arranged grab hooks 72 can realize further crushing work after the preliminary loosening of the ground. In this process, due to the unevenness of the ground, the grab hooks 72 can drive the rod 74 and the rectangular frame 71 to move in the process of grabbing the ground soil. At this time, the bristles 73 on the inner side of the rectangular frame 71 can realize the cleaning work of the loosening block 514, and by setting the second spring 77, the rectangular frame 71 on the later positioning rod 76 can be popped up and reset, thereby increasing the shaking frequency of the rectangular frame 71, further improving the cleaning effect of the cutting surface, and maintaining the edge quality of the loosening block 514. Through the operation of the auxiliary structure 7, while realizing deep loosening of the ground soil, it is convenient to clean the surface of the loosening block 514, and further improving the use effect of the slope loosening structure 5.
