Description

Technical Field

[0001] This utility model relates to the field of seedling transplanting technology, and in particular to a hole punch for transplanting agricultural seedlings. Background Technology

[0002] When raising vegetable seedlings in plug trays or soil, planting holes of a certain size should be made on the mulch film or substrate bag so that the seedlings in the nutrient pots can be planted.

[0003] For example, patent application number CN201520715500.3 discloses a seedling hole puncher. It includes a downward-opening punching cylinder with a piston inside. The piston rod extends from the center of the top surface of the punching cylinder, and a crossbar is attached to the extended end of the piston rod. A scale with gradually increasing values ​​is arranged along the length of the piston rod from top to bottom. When the piston head is positioned parallel to the opening of the punching cylinder, the "0" mark on the scale is parallel to the top surface of the punching cylinder. Two symmetrically arranged strip-shaped slots are arranged on the cylinder wall, extending from the upper section of the cylinder wall to the opening. During punching, the soil height inside the punching cylinder is equal to the distance the piston pushes the piston rod. This pushing distance is directly reflected by the scale on the piston rod, allowing for accurate measurement of the punching depth. These types of hole punchers mostly complete the hole-making operation by pressing down the punching cylinder. Since seedling transplanting requires drilling multiple sets of transplanting holes, and a suitable distance needs to be reserved between two adjacent transplanting holes, in order to ensure that the spacing between seedlings is consistent, the manual hole punching method requires the hole-making position to be determined in advance, which increases the cumbersomeness of the operation and needs to be improved.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a hole punch for transplanting agricultural seedlings, including an outer cylinder 1 and a spring rod 4. The outer cylinder 1 is sleeved on the outside of the spring rod 4 and is slidably connected to the spring rod 4. A handle 2 is fixedly provided on the upper end of the outer cylinder 1, and a push plate 3 is fixedly provided on the upper end of the spring rod 4. The push plate 3 is placed above the handle 2.

[0023] A pressure cylinder 8 is provided below the outer cylinder 1, and a floating plate 15 is provided at the lower end of the spring pressure rod 4. The floating plate 15 is slidably disposed inside the pressure cylinder 8 and fixedly connected to the spring pressure rod 4. A pedal structure is provided between the pressure cylinder 8 and the outer cylinder 1.

[0024] One end of the pedal structure is fixedly connected to the pressure cylinder 8 and the outer cylinder 1, and the other end of the pedal structure is provided with a cone positioning component. The cone positioning component is slidably connected to the pedal structure, and a bolt connector is provided at the connection between the cone positioning component and the pedal structure.

[0025] When drilling, the pressure cylinder 8 is in direct contact with the soil and is inserted into the soil under pressure to form a planting hole. The floating plate 15 slides upward along the inner side of the pressure cylinder 8 under the pressure of the soil. After drilling is completed, push the push plate 3, which will cause the spring pressure rod 4 to push the floating plate 15 down. The floating plate 15 will squeeze out the soil in the pressure cylinder 8 to prevent the soil from sticking together in the pressure cylinder 8.

[0026] The fixed connection between the pedal structure and the pressure cylinder 8 and outer cylinder 1 forms a stable force-bearing support frame. When the operator steps on the pedal structure, the force can be evenly transmitted to the pressure cylinder 8 and outer cylinder 1, allowing the pressure cylinder 8 and the cone positioning component to penetrate the soil more easily. The cone positioning component is inserted into the soil for pre-positioning, ensuring accurate drilling. The sliding and fixing design of the cone positioning component enables precise adjustment and fixation of the drilling position, reduces drilling offset, ensures uniform seedling planting spacing, and improves the uniformity of seedling growth after transplanting.

[0027] It is worth explaining in detail that the inner side of the outer cylinder 1 is provided with a movable ring 16, a positioning ring 17 and a spring 18. The movable ring 16 is sleeved on the outside of the spring pressure rod 4 and is fixedly connected to the spring pressure rod 4. The positioning ring 17 is sleeved on the outside of the spring pressure rod 4 and is fixedly connected to the inner wall of the outer cylinder 1. The positioning ring 17 is slidably connected to the spring pressure rod 4. The spring 18 is fixedly set between the movable ring 16 and the positioning ring 17.

[0028] When the push plate 3 is pressed down, the spring rod 4 drives the movable ring 16 to move downward. The movable ring 16 squeezes the spring 18, putting the spring 18 in a compressed state. When the push plate 3 is released, the spring 18 returns to its original shape, pushing the movable ring 16 to move upward, thereby driving the spring rod 4 and the push plate 3 to reset, preparing for the next drilling.

[0029] Regarding the pedal structure:

[0030] The pedal structure includes a fixing frame 6 and a pedal 5. The upper end of the fixing frame 6 is fixedly connected to the lower end of the outer cylinder 1, and the lower end of the fixing frame 6 is fixedly connected to the upper end of the pedal 5. The lower end of the pedal 5 is fixedly connected to the upper end of the pressure cylinder 8. The pedal 5 and the pressure cylinder 8 have through holes at their tops that allow the spring pressure rod 4 to slide vertically. The spring pressure rod 4 passes through the fixing frame 6 and the through holes at the tops of the pedal 5 and the pressure cylinder 8.

[0031] When the operator steps on pedal 5, the pressure is transmitted to the pressure cylinder 8 through pedal 5, pushing the pressure cylinder 8 into the soil. At the same time, the spring pressure rod 4 can slide vertically along the inside of the fixed frame 6, the pedal 5 and the through hole at the top of the pressure cylinder 8, ensuring that the movement path of the spring pressure rod 4 is stable and does not deviate.

[0032] Regarding the conical positioning component:

[0033] The cone positioning component includes a sliding sleeve 9 and a positioning cone 12. The sliding sleeve 9 is fitted on the outside of the pedal 5 and is slidably connected to the pedal 5. The positioning cone 12 is fixedly installed at the lower end of the sliding sleeve 9.

[0034] After the bolt connector is released from fixing the sliding sleeve 9 and the pedal 5, the sliding sleeve 9 drives the positioning cone 12 to move along the length of the pedal 5. Adjust the distance between the positioning cone 12 and the pressure cylinder 8, thereby adjusting the position of the positioning cone 12 according to the spacing required for seedling transplanting. When the positioning cone 12 moves to the target position, insert it into the soil to determine the precise drilling center point for the hole punch, avoiding deviation in the drilling position.

[0035] More specifically, the bolt connector includes at least one positioning bolt 11, which is fitted onto the upper end of the sliding sleeve 9. The positioning bolt 11 is screwed into the sliding sleeve 9 and threadedly connected to the positioning hole 10 opened on the upper end of the pedal 5. The upper end of the pedal 5 has a plurality of positioning holes 10, which are evenly arranged along the length of the pedal 5.

[0036] The multiple positioning holes 10 expand the positioning adjustment range, enabling the hole puncher to adapt to the transplanting spacing requirements of more seedling varieties and improving the practicality of the hole puncher.

[0037] In the preferred embodiment, the upper end of the pedal 5 is provided with a scale 13, which is located on one side of the positioning hole 10 and is evenly distributed along the length of the pedal 5. When adjusting the position of the sliding sleeve 9, the operator can accurately determine the relative position of the sliding sleeve 9 and the positioning hole 10 by observing the scale 13, and precisely control the spacing between the positioning cones 12 to ensure that the planting spacing of each seedling meets the preset standard.

[0038] In a preferred embodiment, the upper end of the pedal 5 is provided with a diagonal brace 7, which is located at the angle between the outer cylinder 1 and the pedal 5. The upper and lower ends of the diagonal brace 7 are fixedly connected to the outer cylinder 1 and the pedal 5, respectively.

[0039] The diagonal brace 7 connects the outer cylinder 1 and the pedal 5 to form a triangular support structure. By utilizing the stability characteristics of a triangle, the force at the connection between the outer cylinder 1 and the pedal 5 is distributed, which significantly improves the stability and load-bearing capacity of the connection between the outer cylinder 1 and the pedal 5 and extends the service life of the punch.

[0040] How this application works:

[0041] When drilling, the pressure cylinder 8 is in direct contact with the soil and is inserted into the soil under pressure to form a planting hole. The floating plate 15 slides upward along the inner side of the pressure cylinder 8 under the pressure of the soil. After drilling is completed, push the push plate 3, which will cause the spring pressure rod 4 to push the floating plate 15 down. The floating plate 15 will squeeze out the soil in the pressure cylinder 8 to prevent the soil from sticking together in the pressure cylinder 8.

[0042] After the bolt connector is released from fixing the sliding sleeve 9 and the pedal 5, the sliding sleeve 9 drives the positioning cone 12 to move along the length of the pedal 5. Adjust the distance between the positioning cone 12 and the pressure cylinder 8, thereby adjusting the position of the positioning cone 12 according to the spacing required for seedling transplanting. When the positioning cone 12 moves to the target position, insert it into the soil to determine the precise drilling center point for the hole punch, avoiding deviation in the drilling position.
