Description

Technical Field

[0001] The utility model relates to the technical field of agricultural production tools, in particular to a mulch hole puncher. Background Art

[0002] When planting crops, ground film needs to be covered. Covering with ground film can improve the temperature and moisture conditions of the soil and near the ground, increase soil temperature, maintain soil moisture, improve soil properties, improve soil nutrient supply and fertilizer utilization rate, improve light conditions, reduce weeds and pest damage, etc. It can also keep warm and increase temperature, promote the decomposition and release of soil nutrients, retain moisture, and increase survival rate. In addition to irrigation, the soil moisture in the field mainly comes from rainfall. After covering the film, on the one hand, the evaporation of soil moisture is reduced due to the barrier of the ground film, and the loss is slow; and water droplets are formed in the film and then fall to the soil surface, reducing the loss of soil moisture and playing a role in retaining soil moisture. After the ground film is laid, the planting holes need to be punched out with a ground film puncher to facilitate the planting of multiple seeds.

[0003] For example, a mulch puncher with the publication (announcement) number CN218302152U includes a punching device, wherein the punching device includes a hand-held rod, a limiting mechanism is arranged inside the hand-held rod, the limiting mechanism includes a plug-in rod, a hole spacing adjustment mechanism is arranged on the left side of the plug-in rod, and the hole spacing adjustment mechanism includes a sleeve rod, the right outer wall of the sleeve rod is connected to the left end of the plug-in rod, the left side of the sleeve rod is sleeved with an adjusting rod, a limiting pin is inserted into the right inner side of the upper end of the adjusting rod, and the lower end of the limiting pin passes through the sleeve rod and extends to the bottom of the sleeve rod. By setting the hole spacing adjustment mechanism, the distance between the adjusting rod and the punching teeth can be adjusted, so that holes can be punched at a fixed distance according to different crops. There is no need to manually measure the distance between the planting holes and then perform the punching work. Punching is convenient and fast, and the efficiency is higher. The spacing between the planting holes is the same, which improves land utilization and crop growth efficiency.

[0004] However, based on the working principle proposed in the above patent, the applicant believes that since the puncher of the above device is serrated, manual operation requires greater force to penetrate the ground film when punching holes in the ground film, and the puncher must be rotated to separate the punched ground film from the overall ground film. Therefore, when faced with a large amount of work, the manual intensity is high and the efficiency is reduced.

[0005] Therefore, a ground film puncher is proposed to address the above problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The following is combined with Figure 1-5 To further explain this application,

[0025] The embodiment of the present application discloses a ground film puncher, including an extension tube 1, a transmission rod 2 is movably installed inside the extension tube 1, a pressure plate 3 is fixedly installed at the bottom of the transmission rod 2, a first spring 4 is movably installed at the bottom of the pressure plate 3 and located inside the extension tube 1, an assembly block 5 is movably installed inside the extension tube 1 and located at the bottom of the first spring 4, connecting rods 6 are fixedly installed on both sides of the assembly block 5, a curved clamping block 7 is fixedly installed at the end of the connecting rod 6, curved sliding grooves 8 are provided on both sides of the bottom of the surface of the extension tube 1, a second spring 9 is movably installed at the bottom of the assembly block 5 and located inside the extension tube 1, a linkage rod 10 is fixedly installed at the bottom of the assembly block 5, a vertical rod 11 is fixedly installed on the linkage rod 10, and a puncher body 12 is fixedly installed at the bottom of the vertical rod 11.

[0026] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The function of rotating punching of the puncher is realized by the cooperation of the extension tube 1, the transmission rod 2, the first spring 4, the assembly block 5, the connecting rod 6, the curved clamping block 7, the curved slide groove 8, and the second spring 9, thereby ensuring that the saw teeth cut the ground film quickly and evenly, thereby reducing the pressure on the operator, making the punching process easier and more efficient, and the rotating saw teeth can cut the ground film more smoothly, reducing the risk of its overall rupture.

[0027] A limiting cylinder 13 is fixedly mounted on the middle portion of the top inner wall of the punch body 12 , and a telescopic rod 14 is fixedly mounted inside the limiting cylinder 13 .

[0028] Reference Figure 3 and Figure 5 The telescopic rod 14 is used to cooperate with the return spring 17 to form a damping effect. At the same time, the return spring 17 can be limited, thereby ensuring that the force of the return spring 17 is accurately released.

[0029] A T-shaped rod 15 is fixedly mounted on the bottom of the telescopic rod 14 , a separation plate 16 is fixedly mounted on the bottom of the T-shaped rod 15 , and a return spring 17 is sleeved on the surface of the telescopic rod 14 .

[0030] Reference Figure 3 and Figure 5 The T-bar 15 is used to transmit the force of the return spring 17 and the separation plate 16, so as to automatically discharge the ground film produced by punching. The return spring 17 is used to use its tension to push the separation plate 16 to automatically reset. At the same time, the deformable characteristics provide the puncher body 12 with space for lifting and lowering.

[0031] A plurality of positioning holes 18 are provided on both sides of the surface of the extension tube 1. A storage tube 19 is sleeved on the surface of the extension tube 1. Mounting holes 20 are provided on both sides of the bottom of the storage tube 19. Positioning bolts 21 are movably installed inside the mounting holes 20.

[0032] Reference Figure 1 and Figure 2 By cooperating with the positioning hole 18, the storage tube 19, the mounting hole 20 and the positioning bolt 21, the function of increasing the flexibility of the device is achieved, so that the length can be adjusted to suit different operators and operating requirements, thereby reducing the disadvantages of frequently replacing punches of different sizes. At the same time, the telescopic design makes the entire device easier to store and transport when not in use.

[0033] Support rods 22 are fixedly mounted on both sides of the top of the storage tube 19 , and a handle 23 is fixedly mounted on the top of the support rod 22 . A through hole 24 is formed on the top of the handle 23 .

[0034] Reference Figure 1 and Figure 2 The handle 23 makes it easy for the operator to operate the device by holding it, and the through hole 24 provides the required activity space for the transmission rod 2 to be raised and lowered, thereby reducing the mutual wear between the transmission rod 2 and the handle 23.

[0035] An anti-skid pressing pad 25 is fixedly mounted on the top of the transmission rod 2 , and baffles 26 are fixedly mounted on both sides of the bottom of the extension tube 1 .

[0036] Reference Figure 1 、 Figure 2 、 Figure 4 The anti-slip pressing pad 25 is used to increase the friction between the transmission rod 2 and the operator's fingers, while reducing the pressure of the operator's fingers pressing for a long time, thereby increasing the comfort of the device. The baffle 26 is used to close the bottom of the extension tube 1, while ensuring the stability of the second spring 9 during operation, so that the second spring 9 can push the assembly block 5 to reset.

[0037] Working principle: When using this device, take out the positioning bolt 21, pull the extension tube 1, and when the extension tube 1 is adjusted to the appropriate length, install the positioning bolt 21 through the mounting hole 20, and fix the overall length through the positioning hole 18 with the positioning bolt 21. The operator moves the device to the area to be punched through the handle 23, places the punch body 12 on the surface of the ground film to be punched, presses the non-slip pressing pad 25, and transmits the downward pressure through the transmission rod 2. The transmission rod 2 presses the first spring 4 through the pressure plate 3. The first spring 4 is compressed and deformed, and the tension is released to push the assembly block 5. The assembly block 5 is pressed and moves downward, generating pressure on the second spring 9. The second spring 9 is compressed and deformed, providing space for the assembly block 5 to descend. During this period, it is affected by the connecting rod 6 and the curved block 7 in conjunction with the curved slide 8. , resulting in rotation and descent, and as the assembly block 5 rotates and descends, the assembly block 5 drives the punch body 12 to rotate through the linkage rod 10 and the vertical rod 11. As the punch body 12 rotates, the saw teeth rotate and cut the ground film. At the same time, when the punch body 12 rotates and descends, the separation plate 16 contacts the ground film and is affected by the ground to generate resistance. The separation plate 16 generates resistance to the telescopic rod 14 and the return spring 17 through the T-bar 15. The return spring 17 is compressed and deformed, providing space for the separation plate 16 to rise. As the saw teeth of the punch body 12 rotate, the ground film is separated. The operator releases the anti-slip pressing pad 25 and takes out the device. The reset spring 17 releases the tension and pushes the separation plate 16 out of the separated ground film through the T-bar 15. The second spring 9 simultaneously releases the tension to push the assembly block 5 to reset.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
