[0035] Example

[0036] like Figure 1-Figure 4 As shown, a trencher for potato planting includes a mounting plate 1, a trenching shovel 9 and a covering shovel 10. The trencher also includes:

[0037] The screening box 2 is slidably mounted on one side of the mounting plate 1 through a telescopic member 3 11 mounted on the mounting plate 1;

[0038] Screening plate 7, a screening plate 7 is installed in the screening box 2;

[0039] Protective cover 3: A protective cover 3 is provided on one side of the screening box 2, and the screening box 2 is located between the protective cover 3 and the mounting plate 1;

[0040] Screening roller 4, a screening roller 4 is installed in the protective cover 3, and the screening roller 4 is transmission-connected to a driving member 5 installed on the protective cover 3;

[0041] A partition plate 6 is provided at the connection portion between the screening box 2 and the protective cover 3 . The space formed between the partition plate 6 and the top of the inner cavity of the screening box 2 is used for stones to enter the screening box 2 .

[0042] In one case of this embodiment, the trenching shovel 9 is mounted on the mounting plate 1 through a telescopic member 1 91, and the covering shovel 10 is mounted on the mounting plate 1 through a telescopic member 2 101. Moving wheels 13 are also installed on both sides of the mounting plate 1, and a handrail 12 is installed on the top. In addition, the trenching shovel 9, the covering shovel 10, etc. are all prior arts, and this application does not improve them. Therefore, there is no need to disclose their specific mechanical structures, which does not affect the integrity of this application. The telescopic member 1 91 and the telescopic member 2 101 can both be telescopic rods, and the positions of the trenching shovel 9 and the covering shovel 10 can be adjusted by adjusting the telescopic rods. After the section is completed, it can be fixed so that the positions of the trenching shovel 9 and the covering shovel 10 are fixed; the telescopic part three 11 can be a cylinder, or it can be a component that can drive the screening box 2 to move up and down, and the height of the screening roller 4 can be adjusted by the telescopic part three 11, so that the screening roller 4 can be inserted into different layers of soil according to actual conditions; the sliding connection part between the screening box 2 and the mounting plate 1 can be composed of a slider and a chute, the slider is installed on the screening box 2, and a chute is provided on the mounting plate 1, and the slider is slidably installed in the chute, so that the screening box 2 can move up and down in the longitudinal direction to adjust its position; the driving part 1 5 can be a motor, or it can be a component that can drive the screening roller 4 to rotate.

[0043] In actual application of this embodiment, the user pushes the mounting plate 1 and other components connected to the mounting plate 1 through the handrail 12 and the moving wheel 13, and rotates the screening roller 4 through the driving member 15, so that the screening roller 4 is inserted under the soil, and the stones in the soil and on the ground are brought up, and the stones are thrown into the screening box 2 through the space formed by the partition plate 6 and the top of the inner cavity of the screening box 2, so that the stones fall onto the screening plate 7. After screening by the screening plate 7, the stones are left on the screening plate 7, and the soil falls back to the ground. The ground after the stones are cleaned is opened by the trenching shovel 9. Furrow treatment: if planting is carried out while furrowing, the soil that is turned outward on both sides can be covered by the covering shovel 10 to level the soil. If planting is not carried out while furrowing, the covering shovel 10 can be extended upward by the telescopic part 2 101 so as not to contact the ground. Before furrowing, the stones in the soil and on the ground are cleared away by the screening roller 4 and the screening plate 7, so that the furrowing shovel 9 behind is not easily obstructed or damaged during movement, thereby improving the furrowing efficiency and preventing these stones from remaining in the soil and affecting the growth of potatoes.

[0044] When the screening roller 4 is inserted into the ground and lifts up the stones in the ground and on the ground, the screening roller 4 turns the soil, thereby improving the air permeability and air permeability of the soil, so that the potatoes grow better after planting.

[0045] Furthermore, the screening roller 4 comprises:

[0046] The rotating shaft 41 is in driving connection with the driving member 5;

[0047] A plurality of planing boards 42 are provided on the periphery of the rotating shaft 41. The planing boards 42 are arranged in a circular array, and notches are provided on the planing boards 42 at equal intervals.

[0048] Arc-shaped plate 43 : An arc-shaped plate 43 is provided at one end of the planing plate 42 away from the rotating shaft 41 .

[0049] In one case of this embodiment, the width of the notch on the chipping board 42 can be adjusted according to actual conditions so that the stones can be lifted up by the chipping board 42 and thrown into the screening box 2.

[0050] In actual application of this embodiment, the scraping board 42 is inserted into the soil. During the rotation of the scraping board 42 around the rotating shaft 41, the stones in the soil are lifted up. The curved plate 43 is used to effectively prevent the stones from sliding off the scraping board 42. During the rotation of the scraping board 42, the lifted stones are thrown into the screening box 2 due to inertia, thereby cleaning and collecting the stones in the soil. This can effectively prevent the trenching shovel 9 from being blocked or damaged during the trenching process, while improving the trenching efficiency and preventing these stones from remaining in the soil and affecting the growth of potatoes.

[0051] In addition, when the chipping board 42 lifts up the stones, it also lifts up some soil, which then falls back to the ground through the gaps in the chipping board 42. This can turn over the soil, thereby improving the air permeability and air permeability of the soil, and thus making the potatoes grow better after planting.

[0052] Furthermore, the top of the protective cover 3 is arc-shaped. In actual use of this embodiment, after the stones are lifted by the chipper board 42, some of the stones will first contact the top of the protective cover 3 due to inertia, and then slide along the arc portion of the top of the protective cover 3 into the screening box 2; the arc portion of the top of the protective cover 3 allows the stones to enter the screening box 2 smoothly, thereby improving the stone cleaning effect.

[0053] like Figure 2 and Figure 4 As shown, limit frames 71 are symmetrically provided on two opposite surfaces of the inner cavity of the screening box 2 , the screening plate 7 is sleeved in the two limit frames 71 , and a plurality of elastic members 72 are connected between both ends of the screening plate 7 and the two limit frames 71 .

[0054] In one case of this embodiment, the elastic member 72 may be a spring; screening holes are provided on the screening plate 7, and the size of the screening holes is set according to actual conditions so that stones cannot pass through the screening holes.

[0055] When this embodiment is actually used, the stones that enter the screening box 2 will fall onto the screening plate 7. Due to the collision with the screening plate 7, the screening plate 7 is shaken by the rebound ability of the elastic members 72, so that the soil sticking to the stones is screened off by the screening plate 7 and falls back to the ground, while the stones continue to stay on the screening plate 7 and are collected together for convenient centralized disposal later.

[0056] Furthermore, a driving plate 73 is provided on one side of the screening plate 7, and the driving plate 73 passes through the screening box 2. A driving member 3 14 is installed on one side of the screening box 2, and the driving member 3 14 drives the driving plate 73 to drive the screening plate 7 to move back and forth in the horizontal direction.

[0057] In one case of this embodiment, the driving member 3 14 may be composed of a motor and a cam installed at the output end of the motor.

[0058] In actual application of this embodiment, the cam rotates to hit the driving plate 73, which drives the screening plate 7 to move horizontally. Combined with the rebound ability of the elastic member 72, the screening plate 7 moves back and forth in the horizontal direction, so that the stones can be screened and the soil adhering to the stones can be screened off and dropped back to the ground, thereby improving the effect of screening the soil adhering to the stones.

[0059] like Figure 1 、 Figure 2 and Figure 5 As shown, a trimming assembly 8 is installed on the protective cover 3 , and the trimming assembly 8 is located between the rotating shaft 41 and the planing board 42 at the lowest position on the rotating shaft 41 .

[0060] Further, the guide frame 81 is fixed on the protective cover 3;

[0061] The trimming knife 1 82 and the trimming knife 2 83 are both mounted in the guide frame 81;

[0062] Driving member 2 84 : Driving member 2 84 is installed at both ends of the guide frame 81 . The two driving members 2 84 are connected to the trimming knife 1 82 and the trimming knife 2 83 respectively. The two driving members 2 84 drive the trimming knife 1 82 and the trimming knife 2 83 to move crosswise.

[0063] In one case of this embodiment, a plurality of cutters are evenly spaced apart on the pruning blade 1 82 and the pruning blade 2 83 , which can trim weeds or roots on the ground; the driving member 2 84 can be a cylinder or a member capable of driving the pruning blade 1 82 and the pruning blade 2 83 to move horizontally.

[0064] In actual application of this embodiment, the two driving members 2 84 are alternately extended and retracted, so that the pruning blade 1 82 and the pruning blade 2 83 move alternately, so that the cutters of the pruning blade 1 82 and the pruning blade 2 83 will move crosswise. During the movement of this furrow opener, when there are weeds or roots on the ground, the weeds and roots will hit the pruning blade 1 82 and the pruning blade 2 83 and will be trimmed off by the cutters on the pruning blade 1 82 and the pruning blade 2 83. This can effectively prevent the weeds and roots from being entangled on the planing board 42, thereby affecting the normal operation of the planing board 42. At the same time, it can also effectively prevent the furrowing shovel 9 from being blocked by weeds and roots during movement, thereby avoiding affecting the furrowing efficiency.

[0065] Working principle: When in use, the user pushes the mounting plate 1 and other parts connected to the mounting plate 1 through the handrail 12 and the moving wheel 13, and rotates the screening roller 4 through the driving member 1 5, so that the screening roller 4 is inserted under the ground, and the stones in the ground and on the ground are brought up, and the stones are thrown into the screening box 2 through the space formed by the partition plate 6 and the top of the inner cavity of the screening box 2, so that the stones fall onto the screening plate 7, and the cam on the driving member 3 14 rotates to hit the driving plate 73, and the driving plate 73 drives the screening plate 7 to move horizontally, and then cooperates with the rebound ability of the elastic member 72 to make the screening plate 7 move horizontally. The screening plate 7 moves back and forth in the horizontal direction, so that the stones can be screened, the soil sticking to the stones can be screened off and dropped back to the ground, while the stones continue to remain on the screening plate 7 and are collected together for centralized disposal later. The ground after the stones are cleaned is trenched by the trenching shovel 9. If planting is carried out while trenching, the soil turned outward on both sides can be covered by the covering shovel 10 to level the soil. If planting is not carried out while trenching, the covering shovel 10 can be extended by the telescopic part 2 101 so as not to contact the ground.
