Description

Technical Field

[0001] The present application relates to a drip irrigation tape recovery device, and more particularly to a drip irrigation tape lateral recovery device which can automatically lift and reel up an underground drip irrigation tape and then detach the reeled drip irrigation tape from a winding frame. Background Art

After a planting season, the drip irrigation tapes must be recycled before operations in the next season can be carried out.

[0003] The recycling of drip irrigation tape has become a time-consuming and labor-intensive task.

[0004] In recent years, there has been a great development in the recycling machinery of drip irrigation tapes. The drip irrigation tape recycling operation devices disclosed in CN201678321U, CN201553509U, CN201309780Y, CN201240719Y, CN2851202Y, and CN2509153Y mainly use a reel to wind the drip irrigation tape on the reel, and the whole machine moves in the direction of the drip irrigation tape laying. Therefore, in actual use, it is necessary to start winding and recycling from one end of the drip irrigation tape, which will cause the end of the drip irrigation tape to bear a large tensile force when the recycling starts, and the drip irrigation tape breaks frequently. It is necessary to manually pick up the drip irrigation tape and connect it to the recycling reel, which is troublesome and has low work efficiency.

[0034] In the present invention, for the convenience of description, the relative position relationship of each component is described according to the attached manual. Figure 1 The layout is described in detail, such as the positional relationship of top, bottom, left, right, etc. is based on the instructions attached to the manual. Figure 1The layout direction is determined by the traction frame being located at the front, the tipping box being located at the rear, and the driving device being located at the left.

[0035] The present invention is further described below in conjunction with the embodiments and drawings. Figure 1-10 As shown, the drip irrigation tape recovery device includes a frame that can be suspended on the rear side of the traction machine, and a lifting device 3, a driving device 2, a turning device 7, and a winding device 4 are installed on the frame; the frame includes a base 6, columns 5 arranged on the left and right sides of the base 6, and a traction frame 1 arranged on the front side of the base; a lifting device 3 for lifting the drip irrigation tape is arranged on the base 6 between the two columns 5, and a driving device 2 is arranged on one of the columns 5, and the driving device 2 includes a driving box, and a lifting drive shaft 2-1 driven by a first drive motor 2-9, a turning shaft 7-5 and a winding drive shaft 2-2, a flip device 7 is connected to the outside of the driving box, the flip device 7 includes a flip box 7-4 driven by a flip shaft 7-5, a winding device 4 is fixed on one side of the flip box 7-4, the winding device 4 includes a winding frame and a main push rod 4-2 that can move around the winding frame, and the upper part of the main push rod 4-2 can extend into the upper part of the lifting device 3 to hook the drip irrigation tape; the aforementioned lifting drive shaft 2-1 drives the second lifting drive wheel 3-9 to rotate, thereby driving the lifting device 3 to work; the aforementioned winding drive shaft 2-2 drives the push rod drive wheel 7-8 to rotate, thereby driving the main push rod 4-2 to move. The first drive motor 2-9 can be replaced by a hydraulic motor.

[0036] like Figure 1 , 2 As shown, the lifting device 3 includes two side plates 3-4 vertically and parallelly arranged on the base 6, and upper shaft holes are respectively opened on the upper parts of the two side plates 3-4, and upper bearings are arranged in the two upper shaft holes. The lifting drive shaft 2-1 and one end of the upper shaft 3-5 are inserted into the upper bearings, and the other end of the upper shaft 3-5 is rotatably connected to a side column 5. The other end of the lifting drive shaft 2-1 passes through the drive box and is installed with a first winding drive wheel 2-8; the end of the lifting drive shaft 2-1 located between the two side plates 3-4 is equipped with a second lifting drive wheel 3 -9, the upper shaft 3-5 is provided with an upper lifting driven wheel 3-3 at the end between the two side plates 3-4; the lower parts of the two side plates 3-4 are provided with lower shaft holes respectively, the lower shaft holes are provided with lower bearings, the lower shaft 3-7 is connected between the two lower bearings, lower lifting driven wheels 3-6 are provided on both sides of the lower shaft 3-7, a chain is sleeved between the lifting drive shaft 2-1 and a lifting driven wheel 3-6, a chain is sleeved between the upper lifting driven wheel 3-3 and a lifting driven wheel 3-6, and hooks 3-1 are symmetrically distributed on the two chains. The hooks 3-1 are arranged at the uppermost and lowermost ends of the chain.

[0037] Furthermore, a shovel head 3-8 extending forward is provided at the lower end of the side plate 3-4, and an inwardly recessed notch is provided at the junction of the shovel head 3-8 and the side plate 3-4. The shovel head 3-8 can scoop up the drip irrigation belt so that the drip irrigation belt enters the notch. As the second lifting drive wheel 3-9 rotates, the hooks 3-1 on the two chains rotate from back to front along with the chains, and the hooks 3-1 first contact the lower end surface of the drip irrigation belt, and then lift the drip irrigation belt upward to the upper part of the side plate 3-4.

[0038] Furthermore, the hook 3-1 is a rod body with a bent front end. When the hook 3-1 is located at the front side of the side plate 3-4, the front end of the hook 3-1 is bent upward, and when the hook 3-1 is located at the rear side of the side plate 3-4, the front end of the hook 3-1 is bent downward.

[0039] Furthermore, in order to prevent the drip irrigation belt from falling off when it is in a high position, a limit rod 3-2 extending forward is provided on the upper part of the side plate 3-4.

[0040] like Figure 8 , 9 As shown in Figure 10, the winding device 4 includes a winding frame, and the winding frame includes a front outer frame 4-5 and a rear outer frame 4-1 arranged in parallel. The upper ends, left ends and right ends of the front outer frame 4-5 and the rear outer frame 4-1 are not connected, and the bottom ends are fixedly connected. A guide rail is formed between the front outer frame 4-5 and the rear outer frame 4-1, and the rear outer frame 4-1 is fixedly connected to the flip box 7-4 through a connecting plate 7-7; a first push rod driven wheel 4-3 and a second push rod driven wheel 4-6 are respectively arranged at the upper two corners between the front outer frame 4-5 and the rear outer frame 4-1, and the first push rod driven wheel 4-3 and the second push rod driven wheel 4-6 are driven by a push rod driving wheel 7-8. A chain is connected between the three, and a main push rod 4-2 is fixed on the chain. The outer end of the main push rod 4-2 extends out of the winding frame from the guide rail.

[0041] Furthermore, the push rod driving wheel 7-8 is located below the first push rod driven wheel 4-3 and in the middle and upper part between the front outer frame 4-5 and the rear outer frame 4-1. The vertical distance between the push rod driving wheel 7-8 and the bottom end of the front outer frame 4-5 and the rear outer frame 4-1 is greater than the length of the main push rod 4-2. It can be deduced that the vertical distance between any point on the chain between the second push rod driven wheel 4-6 and the push rod driving wheel 7-8 and the bottom end of the front outer frame 4-5 and the rear outer frame 4-1 is greater than the length of the main push rod 4-2. In this way, it can be ensured that when the main push rod 4-2 moves between the second push rod driven wheel 4-6 and the push rod driving wheel 7-8, the main push rod 4-2 is completely located in the front outer frame 4-5 and the rear outer frame 4-1, so that the main push rod 4-2 will only push the drip irrigation belt wrapped around the winding frame to the right.

[0042] Furthermore, the winding frame also includes a front inner frame 4-4 and a rear inner frame arranged in parallel, the front inner frame 4-4 is arranged on the upper part of the front outer frame 4-5, and the rear inner frame is arranged on the upper part of the rear outer frame 4-1, and the front inner frame 4-4 and the rear inner frame wrap the first push rod driven wheel 4-3, the second push rod driven wheel 4-6, and the push rod driving wheel 7-8. The front inner frame 4-4 and the rear inner frame mainly limit the main push rod 4-2 during its movement to prevent it from swinging back and forth.

[0043] Furthermore, a left push rod 4-7 is arranged on the chain on the left side of the main push rod 4-2, and the outer end of the left push rod 4-7 extends out of the winding frame from the guide rail. When the main push rod 4-2 moves to the right, the drip irrigation tape wound on the right side of the main push rod 4-2 is pushed out of the winding frame, and the left push rod 4-7 continues to move to the right to push the drip irrigation tape wound on the left side of the main push rod 4-2 out of the winding frame.

[0044] Furthermore, in order to ensure that the drip irrigation tape is wound within a certain range of the winding frame, a right push rod 4-8 is provided on the chain on the right side of the main push rod 4-2, and the outer end of the right push rod 4-8 extends out of the winding frame from the guide rail. The left push rod 4-7 and the right push rod 4-8 can play a limiting role to ensure that the drip irrigation tape is wound on the winding frame between the main push rod 4-2 and the left push rod 4-7 and the right push rod 4-8.

[0045] When the present application recycles the drip irrigation tape, the moving direction of the whole machine is perpendicular to the laying direction of the drip irrigation tape. As the whole machine moves, the lifting device 3 hooks the drip irrigation tape and transports it upward. At this time, the main push rod 4-2 moves around the winding frame at the same time. When the drip irrigation tape is transported to the upper part of the lifting device 3, the lifting device 3 stops working and the main push rod 4-2 stops moving. At this time, the vertical projection of the main push rod 4-2 is located between the vertical projections of the two side plates 3-4. Subsequently, the flip device 7 drives the winding device 4 to rotate, and the main push rod 4-2 rotates with the winding device 4. The front part of the main push rod 4 extends between the two side plates 3-4 to hook the drip irrigation tape to the winding frame of the winding device 4 and wind it on the winding frames on both sides of the main push rod 4. Subsequently, the flip device 7 stops rotating, and the lifting device 3 starts to hook and lift the next section of the drip irrigation tape. At this time, the main push rod 4-2 moves around the winding frame at the same time, and the main push rod 4-2 pushes the drip irrigation tape wound on the winding frame on one side of the main push rod 4-2 to the side of the winding frame. When the main push rod 4-2 moves to the downward flipping stroke, the drip irrigation tape wound on the winding frame on the other side of the main push rod 4-2 falls off from the side of the winding frame, thereby completing the recycling of the drip irrigation tape. Repeat the above process to recycle the drip irrigation tape.

[0046] like Figure 6 , 7As shown, a cutting device 8 for cutting the drip irrigation tape is provided on one side of the base 6, and the cutting device 8 includes a connecting seat 8-7 fixed on the base 6, a through slot extending vertically through the connecting seat 8-7 is provided in the connecting seat 8-7, a swing rod 8-6 that can swing up and down is hinged in the through slot, a spring seat 8-8 is fixed at the upper end of the through slot, and a spring 8-1 passing through the through slot is provided between the spring seat 8-8 and the swing rod 8-6; a second drive motor 8-5 is provided at the lower end of the swing rod 8-6, and a cutting knife 8-4 is provided on the power output shaft of the second drive motor 8-5; a lower rod 8-2 is provided in the middle and lower part of the swing rod 8-6, and a walking wheel 8-3 is provided at the lower end of the lower rod 8-2. The second drive motor 8-5 can be replaced by a hydraulic motor.

[0047] Furthermore, the cutting knife 8-4 includes a knife disc, which includes two opposite arc segments and two opposite straight segments, and a plurality of cutting teeth are arranged on the arc segments.

[0048] The second drive motor 8-5 can drive the cutting knife 8-4 to rotate. Before recycling the drip irrigation tape, if the drip irrigation tape is long, the whole machine can be driven by the traction machinery to move in a direction perpendicular to the laying direction of the drip irrigation tape. During the movement, only the second drive motor 8-5 is started, so that the drip irrigation tape to be recycled is processed in sections by the cutting knife 8-4. In the process of recycling the drip irrigation tape, the second drive motor 8-5 does not work. As the whole machine moves forward, the walking wheel 8-3 supports the swing rod 8-6 to move with the ups and downs of the ground. At this time, the cutting knife 8-4 is subject to the resistance of the ground, which will make the straight section face the ground, so that the cutting teeth face the front and rear sides, preventing the cutting knife 8-4 from continuing to cut the drip irrigation tape when recycling the drip irrigation tape. At the same time, it also reduces the contact time between the cutting teeth and the ground, protects the cutting teeth, and prolongs the service life of the cutting knife 8-4.

[0049] like Figure 3 , 4 As shown, the flipping device 7 also includes a flipping wheel 7-6 mounted on the flipping shaft 7-5, and the flipping shaft 7-5 is a hollow circular tube with open ends, one end of which is fixedly connected to the flipping box 7-4, and the other end extends into the driving box body; a push rod driving shaft 7-9 with one end extending out of the flipping box 7-4 is provided in the flipping box 7-4, a changing wheel 7-2 is mounted on the push rod driving shaft 7-9 located in the flipping box 7-4, and a push rod driving wheel 7-8 is mounted on the push rod driving shaft 7-9 located outside the flipping box 7-4; the winding device 4 is fixed to the front side of the flipping box 7-4 through a connecting plate 7-7.

[0050] Furthermore, an auxiliary wheel 7-1 is provided on one side of the direction-changing wheel 7-2, which is meshed and linked with the direction-changing wheel 7-2 at 90 degrees. The auxiliary wheel 7-1 makes the force of the direction-changing wheel 7-2 and the winding driven wheel 7-3 balanced.

[0051] like Figure 3 , 4As shown, the driving device 2 also includes a main driving shaft 2-14, a first transition shaft 2-7, and a second transition shaft 2-5, which are arranged in the driving housing and located between the lifting driving shaft 2-1 and the winding driving shaft 2-2.

[0052] Furthermore, the main drive shaft 2-14 in the drive housing is provided with a driven wheel 2-11 and a driving half gear 2-13, the driven wheel 2-11 is meshed and linked with the main drive wheel 2-10, and the main drive wheel 2-10 is provided on the power output shaft of the first drive motor 2-9. The driving half gear 2-13 means that only half of the circumference of the gear plate is provided with continuous teeth, and the other half of the circumference has no teeth and is smooth.

[0053] Furthermore, a first lifting drive wheel 2-12 is mounted on the lifting drive shaft 2-1 in the driving housing, and the first lifting drive wheel 2-12 can be meshed and linked with the driving half gear 2-13.

[0054] Furthermore, the middle of the winding drive shaft 2-2 is located in the driving box, one end of which extends from the turning shaft 7-5 into the turning box 7-4 and is equipped with a winding driven wheel 7-3, which is meshed and linked with the direction-changing wheel 7-2 at 90 degrees, and the other end extends out of the driving box, and the end is equipped with a second winding drive wheel 2-3. The second winding drive wheel 2-3 is linked with the first winding drive wheel 2-8, and a chain is installed between the two, and the second winding drive wheel 2-3 is a flywheel.

[0055] Furthermore, the first large gear 2-18 and the first small gear 2-6 are mounted on the first transition shaft 2-7, and the first small gear 2-6 can be meshed and linked with the driving half gear 2-13.

[0056] Furthermore, a second large gear 2-4 and a second small gear 2-19 are mounted on the second transition shaft 2-5. The second large gear 2-4 is meshed and linked with the flip wheel 7-6, and the second small gear 2-19 is meshed and linked with the first large gear 2-18.

[0057] When the driving half gear 2-13 rotates toward the lifting drive shaft 2-1, as the driving half gear 2-13 meshes with the first lifting drive wheel 2-12, the lifting drive shaft 2-1 rotates, driving the second lifting drive wheel 3-9 and the first winding drive wheel 2-8 to rotate. At this time, the first pinion 2-6 is in a separated state from the driving half gear 2-13.

[0058] After the second lifting drive wheel 3-9 rotates, it will drive the chain to rotate as described above. The hooks 3-1 on the two chains rotate from back to front with the chains. The hooks 3-1 first contact the lower end surface of the drip irrigation belt, and then lift the drip irrigation belt upward to the upper part of the side plate 3-4.

[0059] After the first winding driving wheel 2-8 rotates, it will drive the second winding driving wheel 2-3 to rotate, thereby driving the push rod driving shaft 2-2 to rotate, and then driving the winding driven wheel 7-3, the changing wheel 7-2, the push rod driving shaft 7-9, and the push rod driving wheel 7-8 to rotate in sequence, and finally the chain wrapped around the first push rod driven wheel 4-3, the second push rod driven wheel 4-6 and the push rod driving wheel 7-8 starts to rotate.

[0060] At this time, the main push rod 4-2 starts to move to the right around the winding frame until the driving half gear 2-13 is disengaged from the first lifting drive wheel 2-12, and the main push rod 4-2 just goes around the winding frame once from the starting position and returns to its original position. At this time, the vertical projection of the main push rod 4-2 is located between the vertical projections of the two side panels 3-4, and the hook 3-1 moves upward to the upper part of the side panel 3-4.

[0061] When the driving half gear 2-13 rotates toward the first transition shaft 2-7, as the driving half gear 2-13 gradually meshes with the first pinion 2-6, the driving half gear 2-13 disengages from the first lifting drive wheel 2-12, and the second lifting drive wheel 3-9 and the first winding drive wheel 2-8 no longer rotate. At this time, the first pinion 2-6 drives the first transition shaft 2-7, the first large gear 2-18, the second pinion 2-19, the second transition shaft 2-5, the second large gear 2-4, the flip wheel 7-6, the flip shaft 7-5, the flip box 7-4, and the winding frame to rotate in sequence. Taking the figure shown in the present application as an example, the winding frame rotates from the top to the bottom toward the lifting device 3 side.

[0062] As the winding frame rotates, the main push rod 4-2 will enter between the two side plates 3-4, and the upper part of the main push rod 4-2 will hook the drip irrigation tape located between the upper parts of the side plates 3-4 at this time, and pull the drip irrigation tape to the rotation direction of the winding frame. After the winding frame rotates one circle, the drip irrigation tape can be wound one circle. Assuming that the drip irrigation tape cut by the cutting device 8 is 20 meters long and the winding frame is 40 cm high, the winding frame needs to rotate at least 24 circles to rewind the drip irrigation tape onto the winding frame.

[0063] In this embodiment, the gear ratio of the driving half gear 2-13 and the first lifting driving wheel 2-12, the second lifting driving wheel 3-9, the first pinion 2-6, the first large gear 2-18, the second pinion 2-19, the second large gear 2-4, and the flip wheel 7-6 is 8:1:1:1:3:1:3:1.5, so that each time the driving half gear 2-13 is meshed and linked with the first pinion 2-6, the flip wheel 7-6 rotates at least 24 times, that is, the winding frame rotates at least 24 times. The gear ratio between the gears can be adjusted according to actual needs to control the number of rotations of the winding frame to match the height of the winding frame and the length of the drip irrigation tape.

[0064] In this embodiment, if the height difference between the second lifting drive wheel 3-9 and the lower lifting driven wheel 3-6 is 1.1 meters, and the circumference of the second lifting drive wheel 3-9 is 25 cm, the gear ratio between the control driving half gear 2-13 and the first lifting drive wheel 2-12 and the second lifting drive wheel 3-9 is 8:1:1, so that each time the driving half gear 2-13 engages with the first lifting drive wheel 2-12, the second lifting drive wheel 3-9 rotates at most 4 times, so that the hook 3-1 at the lower end of the chain will lift the drip irrigation tape upward by 1 meter and locate it near the upper end of the side plate 3-4, waiting for the main push rod 4-2 to hook it to the winding frame. The gear ratio between the driving half gear 2-13 and the first lifting driving wheel 2-12 and the second lifting driving wheel 3-9 can be changed according to the height difference between the second lifting driving wheel 3-9 and the lower lifting driven wheel 3-6 to ensure that the lifting height of the hook 3-1 is close to the height difference between the second lifting driving wheel 3-9 and the lower lifting driven wheel 3-6 after each driving half gear 2-13 is engaged with the first lifting driving wheel 2-12.

[0065] In this embodiment, when the winding frame is parallel to the ground, the front part of the main push rod 4-2 is located between the two side plates 3-4, and the front end of the main push rod 4-2 extends forward to the position of the connecting line between the notches of the aforementioned shovel head 3-8, ensuring that the main push rod 4-2 can hook the drip irrigation tape.

[0066] like Figure 3 , 4 As shown in FIG. 5, when the present application is in use, when the first drive motor 2-9 is not started, the winding frame may flip itself under the action of gravity, and at this time the direction-changing wheel 7-2 will drive the push rod drive shaft 2-2 and the second winding drive wheel 2-3 to rotate. Since the second winding drive wheel 2-3 is a flywheel, it will not drive other gears to rotate. However, at this time, the flip box 7-4 will drive the flip shaft 7-5 and the flip wheel 7-6 to rotate, and then drive each transition gear to rotate. Therefore, each transition gear needs to be stopped.

[0067] A first stop gear 2-17 is mounted on the first transition shaft 2-7, and the first stop gear 2-17 is located outside the driving box. A half wheel 2-15 is mounted on the main driving shaft 2-14, and the half wheel 2-15 is located outside the driving box. A first stop rod 2-16 is installed between the half wheel 2-15 and the first stop gear 2-17. Figure 5 As shown, when the half wheel 2-15 rotates clockwise, the half wheel 2-15 touches the upper end of the first stop rod 2-16 and moves upward, so that the lower end of the first stop rod 2-16 moves downward, and the first stop rod 2-16 disengages from the first stop gear 2-17, thereby unlocking.

[0068] Furthermore, the first stop rod 2-16 includes a rod body hinged on the side of the driving box, a spring is connected to the rod body to pull the lower rod body upward, a bayonet consisting of two clamps is provided at the lower end of the rod body, and a force-bearing end extending backward is integrally provided at the upper end of the rod body, the upper surface of the force-bearing end is a plane, the lower surface is an arc surface, and the force-bearing end gradually narrows from the inside to the outside. The bayonet can be buckled on the teeth to limit the rotation of the gear.

[0069] A second stop gear 2-21 is mounted on the lifting drive shaft 2-1, and the second stop gear 2-21 is located outside the drive housing. A half wheel 2-15 is mounted on the main drive shaft 2-14, and a second stop rod 2-20 is installed between the two. Figure 5 As shown, when the half wheel 2-15 rotates clockwise, the half wheel 2-15 touches the lower end of the second stop rod 2-20 and moves downward, so that the upper end of the second stop rod 2-20 moves upward, and the second stop rod 2-20 disengages from the second stop gear 2-21, thereby unlocking.

[0070] The second stop rod 2-20 includes a rod body hinged on the side of the driving box, a spring is connected to the rod body to pull the upper rod body downward, a bayonet consisting of two clamps is arranged at the upper end of the rod body, and the lower end of the rod body is shuttle-shaped. The bayonet can be buckled on the teeth to limit the rotation of the gear.

[0071] Further, the half wheel 2-15 is composed of two semicircular wheels of different sizes, wherein the radius of one wheel is larger than the radius of the other wheel, wherein the smaller wheel will not contact the first stop rod 2-16 and the second stop rod 2-20 when rotating, and the larger wheel will contact the first stop rod 2-16 and the second stop rod 2-20 when rotating. The larger wheel faces the tooth portion corresponding to the driving half gear 2-13.

[0072] In this way, when the driving half gear 2-13 is meshed with the first lifting driving wheel 2-12, the larger wheel disc presses the lower end of the second stop rod 2-20 clockwise downward, so that the upper end of the second stop rod 2-20 is tilted upward, the bayonet is separated from the teeth of the second stop gear 2-21, and the lifting driving shaft 2-1 can rotate. After the larger wheel disc is separated from the second stop rod 2-20, the spring pulls the upper end of the second stop rod 2-20 downward, and the bayonet is engaged with the teeth.

[0073] When the driving half gear 2-13 meshes with the first pinion 2-6, the larger wheel disc rotates to the lower side and rotates upward clockwise, pushing the upper end of the first stop rod 2-16 upward, so that the lower end of the first stop rod 2-16 moves downward, the bayonet is separated from the teeth of the first stop gear 2-17, and the first transition shaft 2-7 can rotate. After the larger wheel disc is separated from the first stop rod 2-16, the spring pulls the lower end of the first stop rod 2-16 upward, and the bayonet is engaged with the teeth.

[0074] The above description is only an example for clearly explaining the present application, and is not intended to limit the implementation methods of the present application. Any obvious changes or modifications derived from the technical solution of the present application are still within the scope of protection of the present application.
