Description

Technical field:

[0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a drip irrigation belt knotting device. Background technology:

[0002] Drip irrigation is a precise irrigation method that uses a low-pressure pipe system to transport water directly to the field. The water is then dripped evenly and slowly into the soil near the root zone of the crop through a drip irrigation belt, creating favorable conditions for high and stable crop yields.

[0003] Manually laying drip tapes takes a lot of time. With the development of agricultural machinery, the current laying of drip tapes is usually done automatically using a drip tape laying device integrated on a seeder, and is equipped with a film and tape breaking device to cut off the ground film and drip tape laid to the field. The ends of the drip tapes are then tied manually to seal them to prevent water leakage at the ends of the drip tapes.

[0004] At present, the knotting operation of the end of the drip irrigation tape is usually done manually. When sowing and laying drip irrigation tapes over a large area, it takes a lot of time and energy to knot the ends of the drip irrigation tapes cut off at the end of the field, which is labor-intensive and inefficient. Summary of the invention:

[0005] The purpose of the present invention is to provide a drip irrigation tape knotting device which saves time and effort and is conducive to improving working efficiency.

The open end of the component is hinged with a swinging scissor-shaped clamp, and the end of the scissor-shaped clamp is hinged with the end of the cylindrical slider through a connecting rod; the other end of the fixed frame is fixed with the motion control component mounted on the grabbing and clamping component, and the end pipe mouth of the motion control component is fixed with a retaining ring; a single cylinder No. 2 is fixed through the side wall of the grabbing and clamping component, a first motion guide rail is fixed on the inner wall of the motion control component, and the second power spring abuts against the single cylinder No. 2; a second guide groove is axially opened on the grabbing and clamping component, and a symmetrical cylinder No. 3 moving along the second guide groove is fixed on the cylindrical slider; a second motion guide rail is fixed on the inner wall of the motion control component.

[0007] Furthermore, the power source is any one of a hydraulic cylinder, a pneumatic cylinder or an electric push rod.

[0008] Furthermore, the fixing frame is a U-shaped structure, first guide grooves are provided on both sides of the fixing frame, and a symmetrical cylinder 2 moving along the first guide groove is fixed to the outer wall of the motion conversion component.

[0009] Furthermore, two baffles symmetrical to the scissor-shaped clamp are fixed to the edge of the open end of the grabbing and clamping component, and the two baffles are in an "eight" shape with the closed ends facing outward; the outer wall of the motion control component is connected to a movable detachable component that is in active contact with the scissor-shaped clamp.

[0010] Furthermore, the movable disengagement component includes a driving rod and an L-shaped rocker arm; a single cylinder is fixed to the outer wall of the motion conversion component, a long groove moving along the single cylinder is opened on the driving rod, a corner point of the L-shaped rocker arm is swingingly set on the outer wall of the terminal tube mouth of the grasping and clamping component, one end of the driving rod is connected to one end of the L-shaped rocker arm, and the other end of the L-shaped rocker arm is fixed with a lever that is in active contact with the scissor-shaped clamp.

[0011] Furthermore, a terminal edge of the motion control component is connected to a fixed detachment component.

[0012] Furthermore, a notch is provided in the side wall of the motion control component, a connecting block is fixed on the outer wall of the motion control component at the notch, a check plate hinged to the connecting block is provided in the notch, a torsion spring is sleeved on the hinge shaft between the check plate and the connecting block, and under the action of the torsion spring, the check plate abuts against the outer wall of the grabbing and clamping component.

[0013] Advantages of the present invention: When in use, the present invention is installed on a seeder with the function of laying ground film and drip irrigation tape. After laying a row of ground film and drip irrigation tape, the drip irrigation tape can be automatically knotted by the present invention, thereby improving work efficiency and reducing manual labor intensity.

[0014] Specifically, the power source drives the motion conversion component and the grabbing and clamping component to move downward, and under the action of the second power spring, the cylindrical slider is pushed, and then the connecting rod pushes the scissor-shaped clamp to between the two baffles, so that the scissor-shaped clamp is closed, and the scissor-shaped clamp flips downward to facilitate insertion into the ground beside the drip irrigation tape to start knotting operation; as the power source continues to extend, the scissor-shaped clamp flips upward to hook up the drip irrigation tape; when the power source drives the motion conversion component to continue to move in a straight line, under the guidance of the spiral groove, the scissor-shaped clamp drives the hooked drip irrigation tape to rotate 270° along with the grabbing and clamping component.

[0015] The telescopic rod of the control power source is contracted, and the motion conversion component begins to be pulled upward, and the grabbing and clamping component moves in the opposite direction. The connecting rod pushes the scissor-shaped clamp to turn down and close at the same time to clamp the drip irrigation tape. As the power source contracts and pulls the motion conversion component to move in the opposite direction, under the guidance of the spiral groove, the grabbing and clamping component is driven by the symmetrical cylinder to rotate in the opposite direction. In the above process, the scissor-shaped clamp holding the drip irrigation tape moves with the grabbing and clamping component, and the fixed detachment component limits the drip irrigation tape arranged around the outside of the scissor-shaped clamp, so that the clamped drip irrigation tape can pass through the wound part, and the fixed detachment component detaches the drip irrigation tape wrapped around the outside of the scissor-shaped clamp; the power source contracts upward to the initial position, and other components also return to the initial position to complete the entire knotting process.

[0041] Baffles 4.9 symmetrical to the scissor-shaped clamp 4.4 are fixed on both sides of the edge of the open end of the grabbing and clamping component 4, and the two baffles 4.9 are arranged in an "eight" shape with the closed opening facing outward, and the opposite side walls of the two baffles 4.9 are inclined downward and inward; when the scissor-shaped clamp 4.4 swings downward, it moves from the open end of the two baffles 4.9 to the closed end, and at the same time, the scissor-shaped clamp 4.4 is closed under the guidance of the two baffles 4.9.

[0045] The present invention is installed on a seeding machine with the function of laying ground film and drip irrigation tape when in use. Specifically, one knotting device is installed before and after the film-breaking and tape-breaking device, and two knotting devices are controlled at the same time. When a row of ground film and drip irrigation tape is laid, the two knotting devices are first controlled to tie a knot before and after the film-breaking and tape-breaking device, and then the film-breaking and tape-breaking device is used to cut the ground film and drip irrigation tape, and the next row of operations is directly carried out. Of course, only one knotting device can be installed, which is installed in front of or behind the film-breaking and tape-breaking device; for example, if it is installed in front of the film-breaking and tape-breaking device, then when a row is almost laid, it is necessary to stop and tie a knot first, and then move forward a little, then another knot can be tied and the film-breaking and tape-breaking operation can be carried out; when a knotting device is installed behind the film-breaking and tape-breaking device, a knot is tied at the end of a row, and another knot is tied after moving forward a little at the starting point of another row; the above-mentioned installation position relationship and corresponding operation operation are common knowledge known to those skilled in the art. Installing the knotting device of the present invention on an existing seeding machine helps to improve the efficiency of knotting operations and the entire seeding operation, and reduce the intensity of manual labor.

[0046] The detailed working process of the present invention is as follows:

[0047] Initial state: Figure 1 and Figure 3 As shown, the power source 2 is in a contracted state, and the symmetrical cylinder 1 4.1 is at the bottom of the spiral groove 3.1 (the end away from the power source 2); the single cylinder 2 4.6 is placed at one end of the motion control component 5 and is in an unconstrained state; the single cylinder 1 6.3 is in contact with one end of the long groove 6.4, and the movable detachment 1 pushes the scissor-shaped clip 4.4 out of the baffle 4.9, and the scissor-shaped clip 4.4 is in an open state under the action of the torsion spring; due to the force of the movable detachment 1 lever 6.5 on the scissor-shaped clip 4.4, the second power spring 4.2 is compressed and deformed, and at the same time, the symmetrical cylinder 3 4.8 on the cylindrical slider 4.3 does not contact the bottom of the second guide groove 4.7.

[0048] Step 1: The scissor-shaped clip 4.4 extends to facilitate insertion into the ground beside the drip irrigation tape

[0049] like Fig. 9 and Fig.10As shown, the power source 2 is started, and its telescopic rod pushes the motion conversion component 3 to start moving. The symmetrical cylinder 1 4.1, the single cylinder 2 4.6, and the symmetrical cylinder 3 4.8 also start to move with the grabbing and clamping component 4. The single cylinder 2 4.6 begins to enter the first motion guide rail 5.2, and the single cylinder 1 6.3 starts to move along the long groove 6.4 with the movement of the motion conversion component 3. The L-shaped rocker arm 6.2 swings under the dead weight of the lever 6.5, and the restriction on the scissor-shaped clamp 4.4 is cancelled. The second power spring 4.2 pushes the cylindrical slider 4.3 during the movement of the grabbing and clamping component 4, and then the connecting rod 4.5 pushes the scissor-shaped clamp 4.4 between the two baffles 4.9, so that the scissor-shaped clamp 4.4 is closed. At the same time, the scissor-shaped clamp 4.4 gradually extends out relative to the motion control component 5 with the grabbing and clamping component 4, so as to be inserted into the ground beside the drip irrigation belt and start the knotting operation.

[0050] Step 2: Flip the scissor-shaped clip 4.4 upward to hook up the drip irrigation tape

[0051] like Figures 11 to 14 As shown, the power source 2 continues to extend, pushing the motion conversion component 3 and the grabbing and clamping component 4 to move, until the symmetrical cylinder three 4.8 on the grabbing and clamping component 4 abuts against the retaining ring 5.1 of the motion control component 5, so that the cylindrical slider 4.3 and the connecting rod 4.5 cannot continue to move, and the grabbing and clamping component 4 continues to move under the guidance of the second guide groove 4.7 and the symmetrical cylinder three 4.8, so that the scissor-shaped clamp 4.4 begins to flip upward under the restriction of the connecting rod 4.5, and the scissor-shaped clamp 4.4 gradually separates from the two baffles 4.9, and under the action of the torsion spring, the scissor-shaped clamp 4.4 gradually opens until the scissor-shaped clamp 4.4 is clamped on the upper edge (highest position) of the grabbing and clamping component 4. In this process, the scissor-shaped clamp 4.4 hooks up the drip irrigation belt; at this time, the second power spring 4.2 is compressed, and the single cylinder two 4.6 passes over the first motion guide rail 5.2 and separates from the linear guide of the first motion guide rail 5.2.

[0052] Process 3: Rotate the scissor-shaped clip 4.4 to wrap the drip irrigation tape and tie it

[0053] like Figures 15 to 17 As shown, when the grabbing and clamping component 4 continues to move until one end of the second guide groove 4.7 is clamped on the symmetrical cylinder three 4.8, it stops linear movement under the limit of the symmetrical cylinder three 4.8 and can only rotate; when the power source 2 drives the motion conversion component 3 to continue to move linearly, under the guidance of the spiral groove 3.1, the symmetrical cylinder one 4.1 drives the grabbing and clamping component 4 to rotate, and at the same time, the symmetrical cylinder three 4.8 and the single cylinder two 4.6 rotate synchronously with the grabbing and clamping component 4 until the single cylinder two 4.6 passes the check plate 8. At this time, the telescopic rod of the power source 2 is fully extended, and the symmetrical cylinder three 4.8 is placed between the second motion guide rail 5.3 and the retaining ring 5.1.

[0054] Step 4: The scissor-shaped clamp 4.4 is turned down and closed to clamp the drip irrigation tape

[0055] like Fig.18 As shown, the telescopic rod of the power source 2 contracts and begins to pull the motion conversion component 3 upward. The symmetrical cylinder three 4.8 cannot move under the limitation of the second motion guide rail 5.3, and under the action of the second power spring 4.2, the grabbing and clamping component 4 moves in the opposite direction. Due to the limitation of the single cylinder two 4.6 by the check plate 8, the grabbing and clamping component 4 cannot rotate. During the reverse linear movement of the grabbing and clamping component 4 relative to the cylindrical slider 4.3, the connecting rod 4.5 pushes the scissor-shaped clamp 4.4 down until it is flipped between the two baffles 4.9. Under the action of the baffle 4.9, the scissor-shaped clamp 4.4 is closed to facilitate clamping the drip irrigation belt.

[0056] At the same time, as the power source 2 contracts, the single cylinder 2 4.6 on the grabbing and clamping component 4 moves in a straight line along the first moving guide rail 5.2 until it disengages from the other end of the first moving guide rail 5.2. At this time, one end of the second guide groove 4.7 is clamped on the symmetrical cylinder 3 4.8, limiting the grabbing and clamping component 4 from continuing to move in a straight line and only allowing it to rotate; in the above process, the scissor-shaped clamp 4.4 holding the drip irrigation tape moves with the grabbing and clamping component 4, and the fixed detachment component 7 limits the position of the drip irrigation tape wrapped around the scissor-shaped clamp 4.4, so that the clamped drip irrigation tape can pass through the wrapped part to facilitate knotting.

[0057] Process 5: Scissor-shaped clamp 4.4 reverse rotation

[0058] As the telescopic rod of the power source 2 continues to contract and pulls the motion conversion component 3 to move in the reverse direction, under the guidance of the spiral groove 3.1 of the motion conversion component 3, the symmetrical cylinder 1 4.1 drives the grabbing and clamping component 4 to rotate in the reverse direction until the symmetrical cylinder 1 4.1 is placed at the bottom of the spiral groove 3.1 (i.e., returns to the initial end away from the power source 2). At this time, the symmetrical cylinder 3 4.8 rotates out from the second motion guide rail 5.3 and is not restricted by it and can move in a straight line. As the telescopic rod of the power source 2 continues to contract, the motion conversion component 3 and the grabbing and clamping component 4 move in a straight line in the reverse direction, and the fixed separation component 7 completes the separation of the drip irrigation belt wrapped around the periphery of the scissor-shaped clamp 4.4.

[0059] When the single cylinder 6.3 moves to one end of the long groove 6.4, under the action of the single cylinder 6.3, the driving rod 6.1 drives the L-shaped swing rod 6.2 to swing, and under the action of the lever 6.5, the scissor-shaped clamp 4.4 is pushed out from the two baffles 4.9. Under the action of the torsion spring, the scissor-shaped clamp 4.4 opens, releases the clamped drip irrigation tape, and the power source 2 shrinks upward to the initial position, and the other components also return to the initial position, completing the entire knotting process.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
