Description

Technical Field

[0001] This utility model relates to an integrated device for cutting, gripping, and pressing film in a high-speed rice transplanter with film covering, belonging to the technical field of film covering accessories for rice transplanters. Background Technology

[0002] Rice mulching transplanting technology can effectively increase soil temperature, retain soil moisture, suppress weed growth, maintain fertilizer efficiency, improve soil, and reduce pests and diseases, thereby achieving the goals of improving quality, increasing yield, and increasing efficiency. However, existing rice transplanters generally lack the function of automatically cutting and holding the mulch film when turning at the edge of the field. The current operating method is: after the machine stops, the mulch film is manually cut, then held with both hands or stretched longer and draped over the transplanting arm. After the machine turns around, the operator bends down to press the mulch film under the mud for fixation. This method has the following significant disadvantages: 1. It seriously affects the continuity of mechanized operations and has low operating efficiency. 2. It increases the number of workers and production costs. 3. It is labor-intensive and poses safety hazards.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings: This embodiment is implemented based on the technical solution of the present invention and provides detailed implementation methods, but the protection scope of the present invention is not limited to the following embodiments.

[0021] like Figures 1-6As shown in this embodiment, a high-speed rice transplanter with film cutting, gripping, and pressing integrated device comprises a high-speed rice transplanter planting section 1 and a film cutting, gripping, and pressing integrated device 2. The film cutting, gripping, and pressing integrated device 2 is installed at the rear of the planting section 1 of the high-speed rice transplanter. The film cutting, gripping, and pressing integrated device 2 includes a fixed frame 11, a lifting frame 12, a front pressing plate 13, a rear pressing plate 14, a rear clamping plate 15, a front clamping plate 16, an upper connecting rod 17, a middle connecting rod 18, a lower connecting rod 19, a film cutting knife 20, and an electric pusher. The frame consists of a rod 21, a self-locking buckle 22, a vertical rod 23, an upper ear plate 24, a middle ear plate 25, a lower ear plate 26, a support rod 27, a connecting plate 28, and a rotating shaft 29. Support rods 27 are fixed to both ends of the fixed frame 11, and vertical rods 23 are fixed to both ends of the lifting frame 12. An upper ear plate 24 is fixed to the upper end of the vertical rod 23, a lower ear plate 26 is fixed to the lower end of the vertical rod 23, and a middle ear plate 25 is fixed to the middle of the vertical rod 23. The motor end of the electric push rod 21 is hinged to the upper ear plate 24, and one end of the upper connecting rod 17 is hinged to the middle ear plate 25. The other end of connecting rod 17 is hinged to one end of middle connecting rod 18, one end of lower connecting rod 19 is hinged to lower ear plate 26, the other end of lower connecting rod 19 is fixedly connected to the upper end of rear pressure plate 15, the upper end of rear pressure plate 15 is fixedly connected to the root of rear pressure plate 14, and a cutting blade 20 is fixed to the lower end of rear pressure plate 15. The push rod end of electric push rod 21 is hinged to the ear plate on lower connecting rod 19, the middle part of middle connecting rod 18 is hinged to the ear plate at the upper end of rear pressure plate 15, and the other end of middle connecting rod 18 is fixed to the upper end of front pressure plate 16. The upper end of 6 is fixedly connected to the root of the front pressure plate. The front pressure plate 13 and the rear pressure plate 14 cooperate with each other. The rear clamping plate 15 and the front clamping plate 16 cooperate with each other. The self-locking buckle 22 is fixed on the fixed frame 11 for movable connection with the lifting frame 12. The fixed frame 11 is used for fixed connection with the rice high-speed transplanter planting part 1. There are two connecting plates 28, which are arranged vertically. One end of each connecting plate 28 is hinged to the upright 23 through the rotating shaft 29. The other end of each connecting plate 28 is hinged to the support rod 27 through the rotating shaft 29.

[0022] The rear pressure plate 14 is arc-shaped.

[0023] The rear clamp 15 and the lower connecting rod 19 are set at a right angle.

[0024] The cutting blade 20 is designed with protruding ends and a concave middle.

[0025] The working principle of this utility model: This utility model achieves film cutting, film gripping, and film pressing by using the front clamping plate 16 and rear clamping plate 15 of the integrated device to move downwards counterclockwise and clockwise, and by closing the front clamping plate 16 and rear clamping plate 15. The implementation process is as follows: Before the film-covering rice transplanter performs the film-covering operation, open the self-locking buckle 22, pull the film-cutting and gripping mechanism backwards and downwards, and then push it against the fixed frame 11, and fasten the self-locking buckle 22; when the film-covering operation reaches the edge of the field, without lifting the seedling platform, continue to press the downward button of the lifting controller, the electric push rod 21 pushes the lower connecting rod 19 to rotate downwards, and the lower connecting rod 19 drives the rear clamping plate 15 and the rear film pressing plate 14 welded to the rear clamping plate 15 to rotate downwards clockwise. At the same time, the upper connecting rod 17 drives the front clamping plate 16 and the front pressing plate 13, which are welded together with the middle connecting rod 18, to rotate counterclockwise downwards. During this process, the cutting blade 20 on the rear clamping plate 15 first contacts the mulch film. The serrated blade completes the cutting action under the continuous push of the electric push rod 21. After the front clamping plate 16 and the rear clamping plate 15 are completely closed, the cut mulch film is clamped by the clamping plate. At the same time, the rear pressing plate 14 presses the end of the laid mulch film into the soil. This completes the whole set of actions of cutting, gripping and pressing the film. Release the down button on the lifting controller. At this time, the film-cutting and gripping mechanism continues to hold the film. Lift the seedling platform, turn the rice transplanter around, and adjust it to the starting position of the next row. Since the electric push rod 21 is locked in the outward pushing position at this time, and the film-cutting and gripping mechanism continues to hold the film in a low position, when the seedling platform is lowered, under the action of the gravity of the entire seedling platform, the film held by the front clamping plate 16 and the rear clamping plate 15 is pressed into the soil. At the same time, the front pressing plate 13 on the front clamping plate 16 completes the pressing action of the film. Press the up button on the lifting controller continuously. The electric push rod 21 pulls the lower connecting rod 19 upward, so that the front clamping plate 16 and the rear clamping plate 15 move upward, clockwise and counterclockwise. The front clamping plate 16 and the rear clamping plate 15 open the film held below, raising the film-cutting and gripping mechanism to the highest position. Release the lifting controller button to start the new row of film covering operation.

[0026] The fixing or fixed connection described in the above embodiments is all welding.

[0027] The above description is merely a preferred embodiment of this utility model. These specific embodiments are different implementations based on the overall concept of this utility model, and the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
