Description

Technical Field

[0001] This utility model relates to the technical field of crop transplanting equipment, and more specifically, to a punching head for tomato transplanting. Background Technology

[0002] Indoor seedling cultivation followed by transplanting to the field is a common agricultural production method, especially for vegetable crops such as tomatoes and peppers. In northern regions, in order to increase soil temperature and maintain soil moisture, plastic film is first laid down, and then holes are punched in the film for transplanting. However, commonly used punching devices are prone to causing the holes to collapse during use, and the soil brought out during the punching process can also fall into the punching location, causing the holes to become filled and blocked.

[0003] For example, the transplanting hole punching machine disclosed in announcement number CN204090481U includes a roller and a punching cone, characterized in that: the cone is rotatably connected to the roller, the rear section of the cone extends and is provided with a small sector gear, a transmission shaft is provided at the center of the roller's rotating shaft, and a large sector gear and a small sector gear are provided on the transmission shaft to mesh.

[0004] As can be seen from the above-mentioned publicly available scheme, when drilling holes, a roller is needed to drive the cone head to penetrate the film and enter the soil to form a hole. However, the hole is formed by compression and is prone to collapse during movement. Moreover, the soil turned over during the drilling process will fall into the formed hole, causing the drilled hole to be filled and blocked. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a perforating head for tomato transplanting. This perforating head, with its conical hollow perforating head, can not only perform perforation during movement, but also move back and forth in the ground to enlarge the hole, preventing the hole from collapsing and greatly improving the perforation quality. Furthermore, through the design of the guide plate, guide surface, and conical through hole, the soil discharged from the through hole can be automatically discharged away from the perforation point during the rotation of the perforating roller, preventing the hole from being filled and blocked by the discharged soil, and facilitating the subsequent hilling up after tomato transplanting.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A perforating head for tomato transplanting includes a perforating roller. A perforating head is fixedly sleeved on the surface of the perforating roller, and a through hole is provided at the center of the perforating head. A storage groove is provided on the side of the perforating roller, and a rotating seat is fixedly connected to the center of the inner wall of the storage groove. A guide plate is fixedly connected to the side of the rotating seat, and a rotating shaft is rotatably connected to the center of the rotating seat. Lower fixing frames are fixedly installed at both ends of the rotating shaft. Symmetrical support rods and symmetrical mounting columns are fixedly installed on the surface of the lower fixing frames. An upper fixing frame is slidably sleeved at one end of each support rod. The bottom of the upper fixing frame is connected to the opposite... One end of the mounting column is fixedly connected, and one end of the upper fixing frame is provided with a drilling machine mounting hole. The drilling machine head for tomato transplanting, through the set conical hollow drilling head, can not only perform drilling work during the movement, but also drill into the ground and move back and forth to enlarge the hole, avoiding the collapse of the drilled hole, greatly improving the drilling quality. In addition, through the set guide plate, guide surface and conical through hole, the soil discharged in the through hole can be automatically discharged away from the drilling point during the rotation of the drilling roller, avoiding the hole being filled and blocked by the discharged soil, and at the same time facilitating the later soil covering after the tomato is transplanted.

[0008] Furthermore, the inner wall of the through hole and the surface of the punching head are both conical. The punching heads are distributed in a ring with equal spacing around the center of the punching roller. The punching heads are set at an angle, which allows the punched holes to be expanded by pressing back and forth when the punching roller rotates.

[0009] Furthermore, the inner wall of the rotating seat is fixedly connected with annularly distributed reinforcing plates, one end of which is fixedly connected with a bushing, and the inner wall of the bushing is fixedly fitted with a sealed bearing, which ensures the rotational stability of the punching roller and the rotating shaft.

[0010] Furthermore, the other end of the guide plate is fixedly connected to the inner wall of the collection trough. The guide plate is made of a high-strength metal plate and has a trapezoidal cross-sectional shape. The guide plate not only supports and strengthens the perforating roller, but also guides the flow, making it easy to discharge the broken soil in the collection trough outward.

[0011] Furthermore, a spring is sleeved on the outer side of the support rod, and a limiting sleeve is connected to the surface of the support rod by a thread. The side of the limiting sleeve is provided with anti-slip protrusions, which facilitate the user to manually rotate the limiting sleeve.

[0012] Furthermore, symmetrical damping sleeves are fixedly fitted onto the surface of the upper fixed frame. The damping sleeves have a central hole and provide damping to prevent the support rod from extending or retracting arbitrarily with the upper fixed frame.

[0013] Furthermore, the surface of the rotating seat is provided with a conical surface, which has the function of guiding airflow.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) The cone-shaped hollow drilling head of this solution can not only perform drilling work during the walking process, but also drill into the ground and move back and forth to expand the hole, so as to avoid the hole from collapsing and greatly improve the drilling quality.

[0016] (2) This scheme, through the setting of guide plate, guide surface and conical through hole, can automatically discharge the soil discharged in the through hole during the rotation of the drilling roller, away from the drilling point, to avoid the hole being filled and blocked by the discharged soil, and at the same time facilitate the later soil covering after the tomato transplanting.

[0025] Example 1

[0026] Please see Figure 1-5 A perforating head for tomato transplanting includes a perforating roller 1, which is mounted at the tail of the perforator via a fixing frame. During the perforator's movement, a perforating head 2 contacts the ground, creating a hole and causing the perforating roller 1 to rotate. Its structure and connection method are existing technology and will not be described in detail here. The perforating head 2 is fixedly sleeved on the surface of the perforating roller 1. A through hole 21 is provided at the center of the perforating head 2, used to insert into the soil to collect loose soil, thus forming a transplanting hole and preventing the loose soil from collapsing and clogging the hole, facilitating the transplanting of tomato seedlings. A receiving groove 11 is provided on the side of the perforating roller 1, and a rotating seat 12 is fixedly connected to the center of the inner wall of the receiving groove 11. The surface of the rotating seat 12 is provided with... The conical surface 17 has a flow guiding function. A flow guide plate 15 is fixedly connected to the side of the rotating seat 12. A rotating shaft 14 is rotatably connected to the center of the rotating seat 12. Lower fixed frames 3 are fixedly installed at both ends of the rotating shaft 14. Symmetrical support rods 31 and symmetrical mounting columns 41 are fixedly installed on the surface of the lower fixed frames 3. An upper fixed frame 4 is slidably sleeved at one end of the support rods 31. Symmetrical damping sleeves 42 are fixedly sleeved on the surface of the upper fixed frames 4. A sleeve hole 43 is provided at the center of the damping sleeves 42. The damping sleeves 42 have a damping function to prevent the support rods 31 and the upper fixed frames 4 from extending and retracting arbitrarily. The bottom of the upper fixed frame 4 is fixedly connected to one end of the symmetrical mounting columns 41. A drilling machine mounting hole is provided at one end of the upper fixed frame 4.

[0027] The inner wall of the through hole 21 and the surface of the punch head 2 are both conical. The punch heads 2 are distributed in a ring with equal spacing around the center of the punching roller 1. The punch heads 2 are set at an angle. The angled punch heads 2 can squeeze and enlarge the punched hole when the punching roller 1 rotates. The inner wall of the rotating seat 12 is fixedly connected with a ring of equally spaced reinforcing plates 13. One end of the reinforcing plate 13 is fixedly connected with a bushing, and the inner wall of the bushing is fixedly fitted with a sealed bearing, which ensures the rotational stability of the punching roller 1 and the rotating shaft 14.

[0028] The other end of the guide plate 15 is fixedly connected to the inner wall of the collection trough 11. The guide plate 15 is made of a high-strength metal plate. The cross-sectional shape of the guide plate 15 is trapezoidal. The guide plate 15 not only supports and strengthens the drilling roller 1, but also guides the flow, making it easy to discharge the broken soil in the collection trough 11 outward. A spring 33 is sleeved on the outside of the support rod 31. The surface of the support rod 31 is connected to the limit sleeve 32 by a thread. The side of the limit sleeve 32 is provided with anti-slip protrusions. The anti-slip protrusions make it easy for the user to manually rotate the limit sleeve 32.

[0029] When using this tomato transplanting hole punch, the agricultural machine drives the hole punching device, causing the punching roller 1 to rotate. Simultaneously, the punching head 2 penetrates the ground covering film and inserts into the soil to form transplanting holes. As the punching roller 1 rotates and pulls the punching head 2 out, the punching head 2 inserted into the soil moves back and forth to enlarge the hole before rotating out of the ground. When the punching head 2 is inserted into the soil, loose soil enters the through-hole 21. Then, when the head 2 rotates to the top of the punching roller 1, the large opening of the conical through-hole 21 faces downwards, causing the loose soil inside to fall into the collection trough 11. At the same time, the vibration generated by the rotating punching roller 1 and the guiding force... The function of the flow plate 15 is to cause the broken soil generated by drilling to fall into the furrow on one side of the drilling roller 1, which is convenient for hilling up after transplanting tomato seedlings. The conical hollow drilling head 2 can not only perform drilling work during the movement, but also move back and forth in the ground to expand the hole, so as to avoid the hole from collapsing and greatly improve the drilling quality. In addition, through the flow plate 15, the flow surface 16 and the conical through hole 21, the soil discharged in the through hole 21 can be automatically discharged away from the drilling point during the rotation of the drilling roller 1, so as to avoid the hole being filled and blocked by the discharged soil, and at the same time, it is convenient for hilling up after transplanting tomatoes.
