Description

Technical Field

[0001] This utility model relates to the field of crop planting technology, and in particular to a film rupture and perforation tool for crop planting. Background Technology

[0002] In agricultural production practices, mulching is commonly used during sowing to ensure good soil moisture, mitigate the damage caused by low temperatures to crops, promote early maturity, and eliminate weeds. Due to its numerous advantages, mulching is widely used in spring sowing in northern China and winter propagation in Hainan.

[0003] Before sowing under plastic film, holes need to be punched in the film. To improve punching efficiency, some manufacturers use plastic film breaker punchers to assist in breaking the film, as shown in the attached image. Figure 1 As shown, a plastic film rupture and perforation tool generally includes a handheld rod 1 and a rupture cylinder 3 with a serrated structure 301 at the lower end. The rupture cylinder 3 is fixed to the lower end of the handheld rod 1 by a fixing frame 2. When rupturing and perforating, the worker holds the handheld rod 1 and then presses the rupture and perforation tool downwards, so that the rupture cylinder 3 is pressed on the plastic film at the position where a hole needs to be made. Under the downward pressure and the shearing action of the serrated structure 301, a hole for planting can be made in the plastic film. In order to collect the cut plastic film, a hook screw 4 that penetrates the inside of the rupture cylinder 3 is usually welded vertically to the lower end of the handheld rod 1. While making a hole, the hook screw 4 also passes through the cut plastic film. Then, when the rupture and perforation tool is lifted, the cut plastic film can be brought out and collected on the hook screw 4 by the action of the thread on the hook screw 4.

[0004] However, as the number of holes increases, more and more cut plastic film will accumulate on the hook screw 4. At this point, the only way to remove the plastic film is to tear it off downwards. However, the threads on the hook screw 4 make it difficult to tear off the plastic film, which makes it difficult for the plastic film breaker to clean up the collected plastic film. The cleaning process is laborious and the ease of use is average. Moreover, each plastic film breaker can only make planting holes of the same size. When it is necessary to make planting holes of other sizes, the plastic film breaker must be replaced directly. This is not convenient in actual use, and its practicality still needs to be improved.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 2 and Figure 3 A film breaker and perforator for crop planting includes a hollow hand handle 1, a film-breaking cylinder 3, and a fixing frame 2 fixed to the lower part of the hand handle 1. The upper end of the hand handle 1 is equipped with a handle for easy gripping by the user, and the lower end of the hand handle 1 is inserted with a hook screw 4. The fixing frame 2 has a hole adapted to the hook screw 4, and the hook screw 4 passes through the hole and is located inside the film-breaking cylinder 3. A sliding component 5 is connected between the hook screw 4 and the hand handle 1. Under the action of the sliding component 5, the hook screw 4 can be driven to retract into the hand handle 1.

[0029] The film-breaking cylinder 3 is rotatably connected to the fixing frame 2. The fixing frame 2 is provided with a fixing component 6 for fixing the film-breaking cylinder 3. The film-breaking cylinder 3 includes a first cylinder 302 and a second cylinder 303 with different diameters. The opening directions of the first cylinder 302 and the second cylinder 303 are opposite, and both of them are provided with a serrated structure 301 at their outer ends for cutting the film.

[0030] Reference Figure 3 and Figure 4 The sliding component 5 includes a sleeve 501 and a connecting sleeve 503. The sleeve 501 is sleeved on the outside of the hand handle 1, and the connecting sleeve 503 is fixedly connected to the upper end of the hook screw 4. A bolt pair 502 is connected between the connecting sleeve 503 and the sleeve 501.

[0031] Reference Figure 5 The bolt assembly 502 includes a bolt 5021 and a nut 5022. The bolt 5021 passes through the sleeve 501 and the connecting sleeve 503. The nut 5022 is threaded onto the thread of the bolt 5021 and is pressed tightly against the outer surface of the sleeve 501. The nut 5022 is a wing nut, which makes it easy to tighten.

[0032] Reference Figure 3 and 5 The head of bolt 5021 is a polygonal prism. The sleeve 501 has a through hole 5011 that matches the head of bolt 5021. The head of bolt 5021 is inserted into the through hole 5011. When the nut 5022 is turned, it can prevent bolt 5021 from rotating. The head of bolt 5021 is pressed tightly against the outer surface of the hand handle 1 by being inserted into the through hole 5011. By cooperating with the nut 5022, the sleeve 501 can be fixed on the hand handle 1, thereby fixing the hook screw 4.

[0033] Reference Figure 3 and Figure 4A through groove 101 is provided on the handle 1 along its length direction. A bolt 5021 is inserted through the through groove 101 and can slide within the through groove 101 along the length direction of the handle 1.

[0034] Reference Figure 3 and Figure 4 The outer surface of the film breaking cylinder 3 is provided with rotating shafts 7 on both sides, and the film breaking cylinder 3 is rotatably connected to the fixed frame 2 through the rotating shafts 7.

[0035] Reference Figure 6 The fixing component 6 includes a fixing base 601, a pin 604, and a connecting hole 605 that is opened on the rotating shaft 7 and adapted to the pin 604. The fixing base 601 is elongated and hollow inside. The pin 604 is slidably connected inside the fixing base 601, and one end of the pin 604 extends downward out of the fixing base 601 and is inserted into the connecting hole 605, thereby fixing the rotating shaft 7 and the film breaking cylinder 3. In this state, the axis of the film breaking cylinder 3 is parallel to the length direction of the hand handle 1.

[0036] The fixing component 6 also includes a toggle block 602 and a return spring 603. The toggle block 602 is fixed on the pin 604, and the return spring 603 is connected between the toggle block 602 and the fixing seat 601. The fixing seat 601 has a guide groove 6011 along the length direction, and the toggle block 602 extends out of the fixing seat 601 by passing through the guide groove 6011.

[0037] In this invention, when the hook screw 4 has accumulated too much cut plastic film and needs to be cleaned, first loosen the nut 5022. This will release the nut 5022 from the clamping of the sleeve 501, and simultaneously release the head of the bolt 5021 from the clamping of the handle 1. This will release the fixation of the sleeve 501 and the hook screw 4. Then, pull the sleeve 501 along the handle 1 away from the hook screw 4. This will cause the hook screw 4 to retract into the handle 1. During the process, the plastic film on the hook screw 4 can be detached from the hook screw 4 under the blocking action of the fixing frame 2. Finally, the detached plastic film can be removed and collected. Then, the sliding sleeve 501 is used to slide it and the hook screw 4 back to their original positions, and the sleeve 501 and the hook screw 4 are fixed by tightening the nut 5022. This achieves the purpose of cleaning the plastic film on the plastic film breaker. Moreover, this cleaning method is obviously faster and more convenient, and there is no need to repeatedly tear the plastic film.

[0038] In the initial state, the first cylinder 302 is below the second cylinder 303. At this time, the first cylinder 302 is used to drill holes in the mulch film. When it is necessary to change the drilling size, the lever 602 is pushed upwards to slide upwards within the fixing seat 601. This causes the pin 604 to be pulled out from the connecting hole 605 on the rotating shaft 7, simultaneously compressing the return spring 603. Then, the mulch-breaking cylinder 3 can be rotated, causing it to rotate 180 degrees along the axis of the rotating shaft 7, thus connecting the first cylinder 302 and the second cylinder 303. After swapping the positions of 03, release the lever 602. Under the action of the return spring 603, the lever 602 and the pin 604 will be pushed back to their original positions, and the pin 604 will be reinserted into the connecting hole 605. This will fix the rotating shaft 7 and the film-breaking cylinder 3 again. In this state, the second cylinder 303 faces downward. At this time, the second cylinder 303 can be used to punch holes in the mulch film, and the size of the punched planting hole can be changed. Moreover, only one film-breaking puncher is needed to punch two sizes of planting holes.
