[0069] In this embodiment, the structure of the groove opening member is as follows: Figure 6As shown, the trenching member is a pointed structure, and the trench end is also the end of the trenching member. In some preferred embodiments, the trench end is slightly curled upward to improve the trenching efficiency. The trenching member also has guide side plates on both sides of the trench end, which can guide the soil to both sides after the trench end is trenched, so as to facilitate the soil covering assembly at the rear to cover the soil.

[0070] In this embodiment, a sowing assembly is provided behind the furrowing member, and a soil covering assembly is provided behind the sowing assembly, which corresponds to the sequence of furrowing, sowing, and then soil covering in the actual planting process. Figure 1 In some embodiments, the sowing assembly also includes multiple planting boxes and multiple seed delivery wheels, and a planting box and a furrowing member are correspondingly arranged on the same reference axis; multiple seed delivery wheels are arranged one by one with the planting boxes.

[0071] For details, please refer to Figure 7 In some embodiments, the covering assembly includes a third fixing rod, a fourth fixing rod and two covering plates, the third fixing rod is provided with a plurality of second adjustment holes, the third fixing rod is connected to the frame through the second adjustment holes by fasteners; the fourth fixing rod includes two third extensions arranged oppositely; and a covering plate is arranged on one third extension.

[0072] In this embodiment, the covering assembly includes a third fixing rod, a fourth fixing rod and two covering plates. The third fixing rod is similar to the first fixing rod. The third fixing rod is provided with a plurality of second adjustment holes which are equidistant and arranged in the vertical direction. The third fixing rod is first adjusted to a suitable height, and then the second adjustment hole which is closest to the height is selected to perform the locking operation between the third fixing rod and the frame.

[0073] A fourth fixing rod is provided below the third fixing rod, the fourth fixing rod is connected to the third fixing rod, the fourth fixing rod may be in a Y-shaped, V-shaped or U-shaped structure, two third extension ends are provided on the fourth fixing rod, the two third extension ends are arranged opposite to each other, and a covering plate is arranged on one third extension. As a preferred embodiment, a bearing may be provided at the connection between the covering plate and the third extension, so that the covering plate can roll relative to the third extension, reduce the friction between the covering plate and the soil during the covering process, and improve the movement smoothness of the entire planting machine.

[0074] In this embodiment, a film covering component is also provided at the rear of the soil covering component, and the film covering component specifically includes a film covering roller, a film pricking roller and a film pressing roller which are arranged in sequence from front to back. Among them, the film covering roller is used to cover the soil with film, and a film roller is sleeved on it. When it is first used, the end of the film wound on the film roller can be first pulled out to the rear of the frame to the rolling area of ​​the film pressing disk, and then the frame is controlled to move forward automatically. A plurality of pricking needles are provided on the outer surface of the film pricking roller, and the pricking needles are distributed in a preset manner. Specifically, the pricking needles can be distributed according to the actual film piercing requirements. The film pricking roller is arranged at the rear of the film covering roller. When the film on the film covering roller rolls down and is laid, the film pricking roller then drives the pricking needles to pierce the film to achieve the piercing requirements of the film. In this embodiment, a film pressing disk is provided on the film pressing roller, and the film pressing disk is arranged near the two side edges of the film, which is used to press the film into the soil, and use the dead weight of the soil to achieve the fixation of the film relative to the soil.

[0075] This embodiment realizes the sequential operation of trenching, planting, soil covering, and film covering in pea planting by setting up a film covering component. Compared with the operation of the existing pea planting machine that covers the film first and then plants, the structure is simpler, and there will be no problem that the pea seeds do not match the holes after the film covering, causing the pea seeds to fall outside the film and the planting fails. In addition, this embodiment does not need to strictly match the puncture holes of the film with the planting points of the pea seeds, which improves the planting efficiency while meeting the requirements of film covering in the pea seed planting stage, thereby improving the planting efficiency.

[0076] See also Figure 2 and Figure 3 In some embodiments, the coating roller is arranged on the lower surface of the frame and extends downward to a first preset distance from the frame; the pricking roller is arranged on the lower surface of the frame and extends downward to a second preset distance from the frame, the second preset distance is greater than the first preset distance, and the pricking needles are in contact with the soil; the film pressing roller is arranged on the lower surface of the frame and extends downward to a third preset distance from the frame, the third preset distance is greater than the first preset distance, and the edge of the film pressing disk is in contact with the soil.

[0077] In this embodiment, the first preset distance between the laminating roller and the frame can be understood as the first preset distance between the center axis of the laminating roller and the lower surface of the frame. Similarly, the second preset distance between the piercing roller and the frame can be understood as the second preset distance between the center axis of the piercing roller and the lower surface of the frame. The third preset distance between the film pressing roller and the frame can be understood as the third preset distance between the center axis of the film pressing roller and the lower surface of the frame.

[0078] Furthermore, the first preset distance is smaller than the second preset distance, and at the second preset distance, the needles of the piercing roller are in contact with the soil, that is, the film-covering roller at the first preset distance remains above the soil, which facilitates the rotation of the film-covering roller without being disturbed by the friction of the soil, and the ground film has a height difference from the film-covering roller to the bottom of the piercing roller, making the covering process of the ground film smoother and not too compact. At the same time, the needles at the second preset distance are in contact with the soil, which can ensure that the needles can effectively pierce the ground film on the upper surface of the soil. At the same time, the contact between the needles and the soil increases the friction between the piercing roller and the soil, so that the piercing roller can drive the needles to roll under the friction, realize the continuous interval piercing operation on the ground film, reduce the number of configurations of drive units such as servo motors, and reduce the production cost.

[0079] In this embodiment, the first preset distance is also smaller than the third preset distance, that is, the third preset distance is larger than the first preset distance. Under this arrangement, the film pressing disk on the film pressing roller can be pressed into the soil. By utilizing the property of the soil to remain soft when covering the soil, the pressing of the film pressing disk will cause the edge of the ground film to be buried in the soil. Driven by the film pressing disk, the soil will be pressed accordingly on the edge of the ground film, thereby achieving the fixation of the edge of the ground film and the soil, and thus completing the fixation of the entire ground film on the soil, that is, the film covering process.

[0080] In some preferred embodiments, bearings can be synchronously provided between the film pressing disc and the film pressing roller to achieve a rotational connection between the film pressing disc and the film pressing roller. Furthermore, bearings can be synchronously provided between the film pressing roller and the frame. When the film pressing disc encounters stones or other obstacles in the soil, it can roll over the obstacles, thereby reducing the frequency of the planter's engagement.

[0081] See also Figure 2 In some embodiments, there are two film pressing rollers which are relatively arranged on the frame, one film pressing roller is provided with a film pressing plate, and each film pressing plate is correspondingly arranged on one side edge of the ground film; or, there is one film pressing roller and two film pressing plates, which are relatively arranged at both ends of the film pressing roller, and each film pressing plate is correspondingly arranged on one side edge of the ground film.

[0082] In this embodiment, there may be two film pressing rollers, which are relatively arranged on both sides of the frame, and one of the film pressing rollers is provided with a film pressing disk to correspond to one side edge of the ground film. In other embodiments, there may be one film pressing roller, which is horizontally arranged below the frame, and a film pressing disk is respectively provided at both ends of the film pressing roller, which can also achieve the film pressing effect on both side edges of the ground film, and this embodiment is not limited to this.

[0083] See also Figure 4 and Figure 5In some embodiments, the seeding box includes a first shell and a second shell, the radial diameter of the first shell gradually decreases from top to bottom along a preset gradient, the first shell is connected to the second shell, and the first shell is used to accommodate pea seeds; the second shell includes a fixing part, an accommodating part and a guide part, the number of the fixing parts is two, which are respectively arranged at both ends of the second shell, the second shell is connected to the frame through the fixing part, a seed delivery wheel is provided in the accommodating part, and the guide part is arranged at the bottom of the second shell, which is arranged corresponding to the seed delivery hole, and the guide part is used to guide the pea seeds.

[0084] In this embodiment, the seeding box includes a first shell and a second shell. The first shell is in the shape of a funnel or an inverted pyramid with a large top and a small bottom. This method facilitates the pea seeds to automatically fall into the seed delivery wheel under the action of their own weight during the planting process. Furthermore, the second shell and the first shell can be integrally formed, wherein the first shell is arranged above the second shell. The second shell is in the shape of a disc, and the second shell includes a fixing portion, a receiving portion, and a guiding portion, wherein the fixing portion is provided with a through hole, such as Figure 4 As shown, the shaft is passed through the through hole to fix the second housing on the frame, and the number of fixing parts can be set according to actual needs. Figure 4 There are two fixing parts shown, which are arranged at the two ends of the second shell body, and the second shell body is fixed to the frame through two shafts. Furthermore, the accommodating part is a hollow area in the second shell body, and a seed delivery wheel is arranged in the accommodating part. The second shell body is provided with an opening at the center point of the seed delivery wheel for the second transmission roller described later to be connected with the seed delivery wheel. The guide part is arranged at the bottom of the second shell body and is connected to the accommodating part. The guide part can be Figure 4 and Figure 5 In the structure shown, the guide part is used to guide the pea seeds to prevent the pea seeds from falling out of the groove.

[0085] Specifically, the seed delivery wheel is disc-shaped, and the seed delivery wheel is a solid disc structure. A plurality of seed delivery holes are provided on the side of the seed delivery wheel. To improve the planting efficiency, the seed delivery holes are arranged in groups of two on the seed delivery wheel in parallel, and the size of the seed delivery holes is smaller than the connection between the first shell and the second shell, and is adapted to the size of the pea seeds. When the seed delivery holes are driven by the seed delivery wheel to rotate to the connection between the first shell and the second shell, the pea seeds will fall into the seed delivery holes under the action of their own weight, and the seed delivery holes are then driven by the seed delivery wheel to rotate to the guide part below, and the guide part guides the pea seeds to correspond to the position of the groove. During the frequent rotation of the seed delivery wheel, the repeated seed delivery operation of the seed delivery holes can be realized.

[0086] See also Figure 1 and Figure 4In some embodiments, the sowing assembly also includes a first transmission roller and a second transmission roller, the first transmission roller is arranged on the frame, and the first transmission roller is transmission-connected to the second driving unit; the second transmission roller is arranged on the frame, and the second transmission roller is arranged parallel to the first transmission roller, and the second transmission roller passes through the accommodating portion to be connected to the seed delivery wheel, and the second transmission roller is transmission-connected to the first transmission roller.

[0087] In the present embodiment, the first transmission roller is arranged on the frame and is connected to the second drive unit. Preferably, the second drive unit and the first transmission roller are transmitted through gear meshing. Furthermore, the second transmission roller and the first transmission roller are connected to each other through a synchronous pulley. This arrangement enables the second drive unit on the frame to be arranged far away from the seed delivery wheel without occupying the space required for the planting box and the seed delivery wheel, thereby improving the space utilization on the frame.

[0088] The planter includes a frame, a moving component, a furrowing component, a sowing component, a soil covering component and a film covering component, wherein the film covering component includes a film covering roller, a film pricking roller and a film pressing roller which are arranged in sequence from front to back, a ground film is sleeved on the film covering roller, the outer side wall of the film pricking roller has a plurality of thorns distributed in a preset manner, the thorns are used to pierce the ground film, and a film pressing roller is provided with a film pressing disk, which is arranged at the edge of the ground film and is used to roll the edge of the ground film into the soil. When in use, the furrowing component can realize the furrowing operation before pea planting, the sowing component can carry out pea planting, and the soil covering component covers the soil after the pea planting is completed. After this operation is completed, the film covering roller lays the ground film in the planting area, the film pricking roller can realize automatic puncture of the ground film, and at the same time, the film pressing roller can press the edge of the ground film to bury it in the soil, so as to achieve fixation between the ground film and the soil.
