Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to an agricultural electric heating ground film perforating machine. Background Technique

[0002] At present, the growth environment of many crops requires raising the ground temperature and maintaining moisture. The existing method is to lay ground film during planting. By laying the ground film, not only can the ground temperature be raised and moisture be maintained, but also the growth of weeds can be inhibited and the growth of crops can be promoted. However, when transplanting crops, it is necessary to punch holes in the ground film at equal intervals according to the planting density. The existing hole-opening methods are as follows: one is to tear (cut) the ground film with fingers or scissors to make holes suitable for the growth of crops. This operation method is relatively cumbersome on the one hand, reducing work efficiency and increasing the burden on planting personnel; on the other hand, when tearing the film, the force may be too large or too small, resulting in excessive tearing and damage of the ground film. The second is a film-breaking device with a handle sold on the market. A toothed iron ring is welded to the handle head, and the film is broken with the teeth, but there will be phenomena such as film entanglement and tearing, which is more laborious and time-consuming than the first method; both methods will simultaneously have incomplete tear openings, and when the wind is strong, the whole ditch of the ground film will be blown up, reducing the utilization rate of the ground film and the effect of heat preservation and moisture preservation of the ground film.

[0003] The Chinese utility model with the publication number CN215188517U discloses an agricultural electric heating ground film perforating machine, which includes a storage battery and a hand-held rod. The storage battery is arranged inside the backpack. One end of the hand-held rod is provided with a heating wire, and the heating wire is connected to the storage battery through a wire. When breaking the film, the heating wire is used to heat-seal the edge of the ground film. At the same time, the heating wire of this utility model is designed to be replaceable, which is convenient to replace heating wires of different specifications according to the size of the seedlings and different growth periods.

[0004] When using the equipment of this solution to punch holes in the ground film, after the hole punching is completed, then pick up the hand-held rod to the next hole punching position to make an opening. However, in the prior art, equidistant hole punching cannot be achieved, resulting in different hole punching positions, which is not conducive to the equidistant growth of plants under the ground film. At the same time, since the ground film is in an arched state before punching, when using the prior art to heat and open the ground film with a heating wire, the middle of the ground film is in an expanded state. Under the heating of the heating wire, the ground film at the hole punching position is prone to wrinkling and pulling, and it is easy to pull and damage the unpunched position of the ground film. For this reason, we propose an agricultural electric heating ground film perforating machine. Content of the Utility Model

[0023] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: An agricultural electric - heating ground - film hole - punching machine includes a female connector 1 and a male connector 2. The bottom of the female connector 1 is electrically connected to a heating wire 3, the male connector 2 is electrically connected to an electric wire 4. A plurality of wire - arranging clips 41 for arranging the electric wire 4 are provided on the outer wall of the hand - held sleeve 61.

An installation hole 11 is opened in the female connector 1, and an exhaust member 7 located at the center of the heating wire 3 is installed at the installation hole 11. An insertion hole 21 is opened at the side wall of the male connector 2, and a distance - determining member 8 is inserted into the insertion hole 21. The adjusting member 6 drives the heating wire 3 to rotate and adjust with the distance - determining member 8 as the center of a circular circumference.

[0024] The top of the female connector 1 is provided with an external thread, the inner wall of the male connector 2 is provided with an internal thread, the female connector 1 and the male connector 2 are in threaded cooperation, the top of the male connector 2 is connected with a hinge seat 12, and the hinge seat 12 is connected with the adjusting member 6.

[0025] The adjusting member 6 includes a hand-held sleeve 61, the bottom of the hand-held sleeve 61 is connected with the hinge seat 12, a telescopic rod 62 is sleeved inside the hand-held sleeve 61, a pressing protrusion 63 is connected to the outside of the telescopic rod 62, and a plurality of adjusting holes 64 cooperating with the pressing protrusion 63 are formed in the outer wall of the hand-held sleeve 61.

[0026] The exhaust member 7 includes a bracket 71 connected to the bottom of the female connector 1, an exhaust rod 72 penetrates through the bracket 71, a limiting plate 73 is connected to the top of the exhaust rod 72, a return spring 74 is connected to the top of the limiting plate 73, and the return spring 74 is connected to the inner wall of the mounting hole 11. The bottom of the exhaust rod 72 is connected with an ellipsoid 75.

[0027] The distance-determining member 8 includes a plug-in post 81 inserted at the plug-in hole 21, a distance-determining plate 82 is connected to the outside of the plug-in post 81, a distance-determining scale 83 is provided on the distance-determining plate 82, a sliding groove 84 is formed in the distance-determining plate 82, a locking block 85 is connected at the sliding groove 84, a distance-determining rod 86 is connected to the locking block 85, a rotating body 87 is connected to the distance-determining rod 86, and a scale rod 88 corresponding to the distance-determining scale 83 is connected to the top of the distance-determining rod 86. The bottom of the distance-determining rod 86 is in a sharp cone shape.

[0028] The power supply for powering is installed in the backpack 5. When in use, the backpack 5 can be carried on the back. The bottom of the heating wire 3 in this solution is in an outer ring shape. After being powered on, the heating wire can burn circular holes in the plastic film. The heating wire 3 is connected to the temperature regulator through the electric wire 4. The temperature regulator adopts a commercially available mature product, such as a 12V 5A DC temperature regulator. The temperature regulator adjusts the heating temperature of the heating wire 3, which is suitable for use in different environments and different seasons. The lower part of the male connector 2 is provided with the female connector 1, and the heating wire 3 is electrically connected to the female connector 1. The male connector 2 and the female connector 1 are detachably connected, which is convenient for replacing heating wires 3 with different diameters, so as to adapt to the plant spacing requirements of different crops; the inner side wall of the male connector 2 is provided with an internal thread, and the upper end of the female connector 1 is provided with a screw rod matching the internal thread of the male connector 2. The screw rod of the female connector 1 can be inserted into the internal thread of the male connector 2 and tightened, ensuring the stability of the installation of the heating wire 3.

[0029] When opening holes in the plastic film, the worker carries a backpack 5 and holds a handheld sleeve 61. According to the plant spacing requirements of the crops, the worker adjusts the position of the locking block 85 on the sliding groove 84. By making the scale rod 88 correspond to the fixed-distance scale 83, the selected position is determined, and the position for the next hole punching is determined. The pointed cone at the bottom of the fixed-distance rod 86 is inserted into the plastic film. Then, the temperature regulator is turned on to preheat the heating wire 3. After the heating wire 3 is preheated, the heating wire 3 is placed on the plastic film at the already determined position. The telescopic rod 62 is pressed, and the pressing protrusion 63 is pressed by hand, so that the telescopic rod 62 can be adjusted inside the handheld sleeve 61. At this time, the ellipsoid 75 first contacts the plastic film. During the continuous downward pressing process, the ellipsoid 75 discharges the excess air at the plastic film along the pointed cone at the bottom of the distance rod 86, facilitating the plastic film at the hole-opening position to be in a flat state. Before the heating wire 3 contacts the plastic film, at this time, the exhaust rod 72 drives the limit plate 73 to compress the return spring 74 upward, so that the heating wire 3 contacts the plastic film, facilitating the heating wire 3 to open a hole in the plastic film under the heating condition. After the hole opening is completed, the heating wire 3 is pulled out upward, and at this time, it rotates along the rotating body 87 connected to the fixed-distance rod 86, so that the holes can be opened at equal intervals at multiple angles at the fixed-distance position. The inside of the rotating body 87 in this solution is in a gear meshing state, and the same number of teeth is rotated each time, which is convenient for adjusting the corresponding angle. For example, it can be rotated and adjusted by 90°, so that the holes can be opened at equal intervals in a circle at the fixed-distance point position. When initially opening a hole, the plug-in column 81 can be rotated to facilitate raising the fixed-distance rod 86 by a certain angle, which is convenient for the heating wire 3 to open the first hole. After the first hole is completed, the bottom of the fixed-distance rod 86 can be inserted into the center of the first hole. Because the ellipsoid 75 presses downward first, the fixed-distance rod 86 can be inserted at the position of the ellipsoid 75. On the one hand, it performs heat-edge opening on the plastic film, and on the other hand, it makes the lower tip of the positioning rod pierce the plastic film, completing the position for the next film-breaking hole opening, ensuring the uniformity of the break aperture and the consistency of the plant spacing, improving the labor efficiency, and reducing the labor intensity of manual hole punching.
