Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting devices, in particular to an agricultural film flanging and rope threading device. Background Art

[0002] Agricultural film, also known as plastic film, is mainly composed of polyethylene and is mainly used to cover farmland and greenhouses. It plays a role in increasing ground temperature, maintaining soil moisture, and promoting seed germination and rapid growth of seedlings. When agricultural film is used in greenhouses, ropes need to be threaded on both sides of the edges to fix it on the greenhouse.

[0003] As described in the prior art (Chinese patent number CN216001501U), "after farmers purchase agricultural films, they thread ropes manually. However, agricultural films are often very long, and manual threading is not only time-consuming and labor-intensive, but also inefficient and may damage the agricultural films, thus affecting their use." That is, during current agricultural greenhouse cultivation, it is necessary to drill holes in the agricultural films, thread ropes through the holes, and then tie the ropes to the greenhouse racks to fix the agricultural films to the greenhouse racks. However, when threading the films manually, the films may be damaged, and the repeated flanging and punching of the films back and forth can easily cause farmers to have a high intensity of physical labor.

[0004] Therefore, we propose an agricultural film flanging and rope threading device. Utility Model Content

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] See also Figure 1-Figure 3 The utility model provides a technical solution: an agricultural film flanging and rope threading device, comprising:

[0039] A handle 21 and a connecting block 12 arranged at one end of the handle 21, wherein the handle 21 is used for farmers to hold and use, and the connecting block 12 is welded to one end of the handle 21;

[0040] A lower clamping plate 15 is provided on the connecting block 12, and the bottom of the lower clamping plate 15 is welded to the upper end surface of the connecting block 12;

[0041] The upper clamping plate 18 is pivotally connected to one end of the lower clamping plate 15 and abuts against the surface of the lower clamping plate 15 after being turned over. Specifically, one end of the upper clamping plate 18 is provided with a protrusion extending downward, and a pivot is fixedly connected between the two protrusions. The lower clamping plate is provided with a pivot mounting hole for the pivot to freely pass and rotate, so that the upper clamping plate and the lower clamping plate can be folded and turned over, and after folding, the opposite surfaces of the upper clamping plate and the lower clamping plate abut against each other;

[0042] A driving part for driving the upper clamping plate 18 to rotate along the pivot axis with the lower clamping plate 15, and driving the upper clamping plate 18 to flip through the driving part, so that the upper clamping plate 18 and the lower clamping plate 15 are folded and flipped;

[0043] A floating pin 9 is vertically slidably inserted into the lower clamping plate 15, and a pointed head 11 is provided at the upper end of the floating pin 9. A first through hole 19 is provided on the upper clamping plate 18 for the floating pin 9 to pass freely. In addition, a second through hole 14 is provided on the lower clamping plate for the floating pin to pass freely.

[0044] The floating part is used to drive the floating pin 9 to move upward during the turning over of the upper clamping plate 18. The floating part drives the floating pin 9 to move upward, so that the pointed head 11 can poke open the agricultural film pressed between the upper clamping plate and the lower clamping plate.

[0045] In the agricultural film flanging and rope threading device described in the utility model, the user holds the handle 21, and at this time the driving unit drives the upper splint to flip in the direction away from the lower splint, that is, the upper splint and the lower splint are flipped to the unfolded state, and then the upper splint and the lower splint are placed under the agricultural film and moved toward the inner side of the agricultural film until the edge of the upper splint is away from the edge of the lower splint and is as flush as possible with the edge of the agricultural film, and then the driving unit is activated, and the driving unit drives the upper splint to flip. During the flipping process, the upper splint can flip the edge of the agricultural film 90°, so that the edge of the agricultural film is flanging. After flipping into place, the upper splint is against the surface of the lower splint, and the agricultural film is squeezed by the upper splint and the lower splint. During the flipping process of the upper splint, the floating unit will drive the floating pin to move upward, so that the pointed head can poke the agricultural film, and then perforate the surface of the agricultural film, which is convenient for subsequent farmers to pass the rope into the perforation.

[0046] like Figure 1-Figure 3As shown, an end of the upper clamping plate 18 away from the pivotal connection with the lower clamping plate 15 is provided with an upwardly extending baffle 20, and the function of the baffle 20 is to limit the edge of the agricultural film when the upper clamping plate and the lower clamping plate are flipped to the unfolded state, so that the position of the upper clamping plate extending into the inner side of the agricultural film is basically the same each time, and a notch 13 is opened on the lower clamping plate 15 for the baffle 20 to pass freely.

[0047] In the agricultural film flanging and rope threading device described in the utility model, when the upper and lower splints are extended under the agricultural film, the baffle is abutted against the edge of the agricultural film, so that the position of the upper splint extending into the inner side of the agricultural film is basically consistent each time, and after the upper splint is flipped over to fold the lower splint, the baffle can be stuck in the notch 13.

[0048] like Figure 1-Figure 3 As shown, the driving unit includes:

[0049] The electromagnet 1 is fixedly mounted on the handle 21, and the electromagnet 1 is powered by a battery installed in the handle 21, which is convenient for handheld operation;

[0050] The sliding ring 4 is slidably mounted on the handle 21, and the electromagnet 1 is used in conjunction with the sliding ring 4, that is, when the electromagnet 1 is powered on, it will generate magnetism and generate magnetic attraction on the sliding ring 4, so that the sliding ring 4 slides on the handle 21 toward the electromagnet;

[0051] A gear 16 fixed to the upper clamping plate 18 and coaxial with the pivot axis of the upper clamping plate 18 on the lower clamping plate 15;

[0052] A connecting rod 3 provided on a sliding ring 4;

[0053] The rack 10 is arranged on the connecting rod 3 and meshes with the gear 16 externally.

[0054] In the agricultural film flanging and rope threading device described in the utility model, after the power supply of the electromagnet 1 is turned on, the sliding ring is subjected to the magnetic attraction force of the electromagnet 1, thereby driving the sliding ring to move in the direction of the electromagnet, so that the sliding ring drives the connecting rod and the rack to move. When the rack moves, it will mesh with the gear for transmission, thereby driving the upper clamping plate to flip, and then the upper clamping plate and the lower clamping plate are folded together.

[0055] like Figure 1-Figure 3 As shown, a spring 2 is wrapped around the handle 21, and two ends of the spring 2 in the elastic force direction elastically press against the sliding ring 4 and the electromagnet 1 respectively.

[0056] In the agricultural film flanging and rope threading device described in the utility model, through the setting of spring 2, when the sliding ring moves toward the electromagnet, it will compress the spring 2. When the electromagnet loses its magnetism after power is turned off, the elastic potential energy accumulated in the spring will drive the sliding ring to move away from the electromagnet, causing the rack and the gear to rotate in opposite directions, so that the upper and lower clamping plates are flipped to the unfolded state.

[0057] like Figure 1-Figure 3 As shown, the floating part includes:

[0058] A crossbar fixed to the inner wall of the sliding ring 4, a waist-shaped hole 17 is provided on the handle 21 for the crossbar to move freely through, and the length direction of the waist-shaped hole 17 is parallel to the axial direction of the handle 21;

[0059] A fixed rod 5 connected to the crossbar and coaxial with the handle 21, the fixed rod 5 slides through the handle 21 and the connecting block 12;

[0060] A floating frame 8 is fixed to the lower end of the floating pin 9, and a clearance groove is provided on the floating frame 8 for the fixed rod 5 to pass freely, and the width of the clearance groove is at least not less than the outer diameter of the fixed rod 5;

[0061] A sliding pin 6 is passed through the end of the fixed rod 5 away from the handle 21, and a waist-shaped groove 7 is provided on the floating frame 8 for the sliding pin 6 to be inserted into. The length direction of the waist-shaped groove 7 forms an angle with the axial direction of the floating pin 9, and the minimum value of the angle is less than 90°.

[0062] In the agricultural film flanging and rope threading device described in the utility model, when the sliding ring slides on the handle 21, it will drive the fixed rod 5 to move. When the fixed rod 5 moves, the sliding pin 6 slides in the waist-shaped groove. When sliding, since the length direction of the waist-shaped groove forms an angle with the floating pin, when the fixed rod moves in the direction adjacent to the handle 21, the sliding pin moves in the waist-shaped groove toward the lower end of the waist-shaped groove, thereby causing the floating frame to move upward.

[0063] like Figure 1-Figure 3 As shown, the included angle is 45°, which makes the sliding pin have less resistance when sliding in the waist-shaped groove.

[0064] like Figure 1-Figure 3 As shown, the sliding pin 6 is made of stainless steel. Similarly, such a configuration makes the sliding pin have less resistance when sliding in the waist-shaped groove.
