Description

Technical Field

[0001] The present invention relates to the technical field of seabuckthorn cultivation and watering, and specifically refers to a water control type watering device for seabuckthorn planting and cultivation. Background Art

[0002] Seabuckthorn cultivation includes sowing cultivation and cutting propagation. For sowing cultivation, first select a seedling raising land, and choose a high bed or a low bed for bed making. Then sow the seeds. After sowing, watering is required. When watering, it is necessary to ensure that the water can penetrate into the deep layer of the soil. For high bed cultivation, the height of the high bed is 18 - 20 cm, the width of the bed is 80 - 100 cm, and the path is 25 - 30 cm. Since the high bed is higher than the ground, its drainage is good. At the same time, the soil on the bed surface is loose and the air circulation is smooth. When planting, in order to ensure sufficient nutrition for the seeds, there will be a certain planting spacing. In order to improve the drainage effect, the height of the planting spacing is flush with the ground, so as to ensure that when watering, it can prevent excessive watering from causing water to accumulate on the high bed.

[0003] After sowing the seeds, watering is required. The watering needs to be moderate. Too little watering cannot meet the growth needs of the seeds, and too much watering will cause the seeds to rot. Currently, when watering the seeds, most rely on manually pulling the water pipe and then watering the seeds on the high bed in turn. When watering, since the water pipe is always discharging water and there is a certain planting distance between the seeds, inevitably, water will be poured on the place without seeds during the process of moving the water pipe. There are also some automatic watering devices in the prior art, but in actual use, the automatic watering devices will also pour water on the place without seeds, wasting water resources, and the amount of watering is mostly fixed and cannot be adjusted according to specific situations.

Detailed implementation manner

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Combined with the attached Figure 1 、 attached Figure 2 、 attached Figure 4 As shown, a quantity-controlled watering device for seabuckthorn planting and cultivation includes a watering truck 1, a water storage cylinder 2 is provided on the watering truck 1, a bracket 3 is provided on the watering truck 1, a quantity control box 4 is provided on the bracket 3, a connecting pipe 41 that penetrates the bracket 3 and is connected to the bottom of the quantity control box 4 is provided on one side of the water storage cylinder 2, a piston 42 is slidably provided in the quantity control box 4, a control mechanism 5 for controlling the watering amount is provided on the quantity control box 4, a plurality of water outlet pipes 43 extending to the bottom of the watering truck 1 are provided at the bottom of the quantity control box 4, a sealing plug 44 for controlling the opening and closing of the water outlet pipe 43 is hinged to the bottom surface of the watering truck 1, a trigger mechanism 6 that adaptively adjusts according to the planting spacing is provided on the watering truck 1, and the trigger mechanism 6 controls the movement of the piston 42 and waters the seeds.

[0025] Working principle of the present invention: In actual planting, the positions between the high beds are not fixed. In order to adapt to the unfixed positions, a triggering mechanism 6 that can be adjusted adaptively according to the planting spacing is provided. Only when the water outlet pipe 43 is located above the high bed, the sealing plug 44 opens, and at the same time, the triggering mechanism 6 controls the piston 42 to move downward. The piston 42 can assist in squeezing out the water and can also suck the water in the water storage cylinder 2 into the metering box 4 to control the watering amount. Thus, when the watering vehicle 1 is moving continuously, the watering is intermittent. By setting the control mechanism 5, the watering amount can be adjusted to ensure that the watering amount is appropriate.

[0026] Combined with the attached Figure 1 、the attached Figure 2 、the attached Figure 3 As shown, the control mechanism 5 includes an adjustment component 51 for controlling the downward movement amount of the piston 42 and a movement component 52 for controlling the movement of the piston 42. The adjustment component 51 includes a screw rod 53 on the metering box 4 and two limit posts 54. A limit plate 55 is slidably arranged on the screw rod 53 and sleeved on the two limit posts 54. A bolt 56 is threadedly connected to the screw rod 53, and the bolt 56 is located on the limit plate 55. Two connecting plates 57 are provided on the piston 42. A clamping plate 58 that cooperates with the limit plate 55 is provided on the connecting plate 57, and the clamping plate 58 abuts against the bottom surface of the limit plate 55. A return spring 59 is provided between the connecting plate 57 and the metering box 4.

[0027] Working principle of the adjustment component 51: In order to control the watering amount, an adjustment component 51 for controlling the moving distance of the piston 42 is provided. By controlling the moving distance of the piston 42, the watering amount can be controlled. During specific use, rotate the bolt 56 to make the limit plate 55 at the uppermost position, press down the connecting plate 57 until the piston 42 fits against the bottom surface of the metering box 4, add water to the water storage cylinder 2, and then release the connecting plate 57. The piston 42 moves upward and sucks the water in the water storage cylinder 2 into the metering box 4. At this time, the piston 42 is at the uppermost position in the metering box 4. Then seal the water storage cylinder 2 with a sealing cover, insert the humidity sensor into the high bed at a specified distance, open the sealing plug 44, and then manually press the connecting plate 57. The piston 42 moves downward, and the water flows out of the metering box 4. When the humidity in the humidity sensor is appropriate, record the distance that the limit plate 55 moves downward at this time, and then rotate the bolt 56 so that the distance from the upper surface of the metering box 4 to the limit plate 55 is equal to the distance that the piston 42 moves downward. Thus, the distance that the piston 42 moves downward each time is fixed, and the watering is uniform. After the watering is completed, the return spring 59 drives the connecting plate 57 to reset. Since the sealing plug 44 is closed at this time, when the piston 42 moves upward, it will suck the water in the water storage cylinder 2 into the metering box 4, so as to carry out the next watering; When the amount of watering is small, the limiting plate 55 is lifted by rotating the bolt 56, and the connecting plate 57 is pushed by the return spring 59 to move to abut against the limiting plate 55. At this time, the volume of the cavity formed between the piston 42 and the metering box 4 becomes larger, so that when watering, the outflow of water increases; When the amount of watering is large, the limiting plate 55 is lowered by rotating the bolt 56, and the connecting plate 57 in contact with it also moves down accordingly. At this time, the volume of the cavity formed between the piston 42 and the metering box 4 becomes smaller, and when watering, the outflow of water decreases.

[0028] Combined with the attached Figure 1 and attached Figure 2 and attached Figure 3 As shown in the attached drawings, the moving assembly 52 includes a rotating shaft 510 rotatably arranged between the brackets 3. Both ends of the rotating shaft 510 are provided with winding rollers 511. A driving plate 513 is slidably arranged on the connecting plate 57. A limiting sleeve 512 is arranged on the connecting plate 57. A plug post 514 slidably arranged in the limiting sleeve 512 is arranged on the bottom surface of the driving plate 513. A first spring is arranged between the plug post 514 and the limiting sleeve 512. A connecting rope 516 wound around the winding roller 511 is arranged on the bottom surface of the driving plate 513.

[0029] Working principle of the moving assembly 52: Since the adjusting assembly 51 is provided, and the distance that the moving assembly 52 moves each time is fixed, a limiting sleeve 512 is arranged on the connecting plate 57, and a plug post 514 is arranged on the driving plate 513. When the moving assembly 52 drives the piston 42 on the connecting plate 57 to move to the bottommost position, the driving plate 513 continues to move down and compresses the first spring, drives the rotating shaft 510 to rotate by driving, the rotating shaft 510 drives the two winding rollers 511 to rotate, and the winding rollers 511 wind up the connecting rope 516, thereby driving the driving plate 513 to move down.

[0030] Combined with the attached Figure 1 and attached Figure 2 and attached Figure 4 and attached Figure 5 and attached Figure 9 As shown in the attached drawings, the triggering mechanism 6 includes a rotating assembly 61 for driving the sealing plug 44 to rotate and a rotating mechanism 7 for driving the rotating shaft 510 to rotate. The rotating assembly 61 includes a U-shaped plate 63 slidably arranged on the watering cart 1. The U-shaped plate 63 is fixed by a threaded rod. A threaded rod is rotatably arranged on the U-shaped plate 63. One end of the threaded rod is threadedly connected to the bracket 3. A first rotating column 62 is rotatably arranged on the U-shaped plate 63 at the bottom surface of the watering cart 1. Two triggering plates 610 are arranged on the first rotating column 62. A second rotating column 66 is rotatably arranged on the bottom surface of the watering cart 1 on one side of the water outlet pipe 43 and a torsion spring 64 is arranged between the second rotating column 66 and the watering cart 1. An L-shaped plate 65 is arranged on the second rotating column 66. The sealing plug 44 is arranged on the L-shaped plate 65; A driving gear one 67 is provided on the rotating column one 62, and a driving gear two 68 is provided on the rotating column two 66. An expansion and contraction rack 69 that meshes with the driving gear one 67 and the driving gear two 68 respectively is provided on the bottom surface of the watering vehicle 1. The expansion and contraction rack 69 is slidably arranged on the bottom surface of the watering vehicle 1 and can expand and contract as the position of the U-shaped plate 63 changes; The expansion and contraction rack 69 includes a rack one 691 that meshes with the driving gear one 67. A rack two 692 that meshes with the driving gear two 68 is slidably arranged on the bottom surface of the watering vehicle 1. One end of the rack two 692 is provided with an insertion block 693. A slot that cooperates with the insertion block 693 is provided on the rack one 691. A bolt for fixing the insertion block 693 is threadedly connected to the rack one 691.

[0031] Working principle of the rotating assembly 61: In order to drive the rotation of the rotating shaft 510 while controlling the watering above the high bed. According to the characteristics of the high bed, the height of the high bed is 18 - 20 cm. A trigger plate 610 is set. When the trigger plate 610 contacts the high bed, due to the certain height of the high bed, it will block the movement of the trigger plate 610, thereby causing the trigger plate 610 to rotate. The trigger plate 610 drives the driving gear one 67 to rotate. The driving gear one 67 drives the driving gear two 68 to rotate through the expansion and contraction rack 69, so that the sealing plug 44 moves away from the water outlet pipe 43. Then the trigger plate 610 rotates to drive the rotating mechanism 7, and the rotating mechanism 7 drives the rotating shaft 510 to rotate, so that water is discharged from the water outlet pipe 43. During specific use, the fixing of the U-shaped plate 63 is released by the threaded rod, and at the same time, the fixing between the rack one 691 and the rack two 692 is released by the bolt. Then the position of the U-shaped plate 63 on the watering vehicle 1 is adjusted so that the water in the water outlet pipe 43 can fall on the high bed after the trigger plate 610 on it rotates when contacting the high bed. Then the U-shaped plate 63 is fixed with the threaded rod, and the rack one 691 and the rack two 692 are fixed with the bolt.

[0032] Combined with attached Figure 1 、attached Figure 2 、attached Figure 4 、attached Figure 6 、attached Figure 7 、attached Figure 8 As shown in the attached figures, the rotating mechanism 7 includes a gear one 71 provided on the power shaft of the watering vehicle 1. A rotating shaft 710 is rotatably provided on the watering vehicle 1. A gear two 72 that meshes with the gear one 71 is rotatably provided on the rotating shaft 710. A sleeve 73 is provided on one side of the gear two 72. An internal gear ring 74 is slidably arranged on the sleeve 73 and the rotation of the sleeve 73 can drive the internal gear ring 74 to rotate. A gear three 75 is rotatably provided on the rotating shaft 710. A transmission assembly 76 for driving the rotating shaft 510 to rotate when the gear three 75 rotates is provided between the gear three 75 and the rotating shaft 510. The internal gear ring 74 moves to mesh with the gear three 75 and drives the gear three 75 to rotate. The watering vehicle 1 is driven by a motor to move the wheels; The transmission assembly 76 includes a driving wheel 761 disposed on one side of the third gear 75. A driven wheel 762 is provided on the rotating shaft 510. A transmission belt 763 is provided between the driving wheel 761 and the driven wheel 762; The rotating mechanism 7 further includes a circular ring 77 rotatably disposed on the internal gear ring 74. An extension rod 78 is provided on the circular ring 77. One end of the telescopic rack 69 is provided with an inclined block 79 that drives the extension rod 78 to move when the telescopic rack 69 moves; A fixing rod 8 is provided on the bottom surface of the watering cart 1. A limiting strip 81 for limiting the extension rod 78 is provided on one side of the fixing rod 8. A second spring 82 is provided between the fixing rod 8 and the extension rod 78.

[0033] Working principle of the rotating mechanism 7: In order to be able to automatically drive the rotation of the rotating shaft 510 according to the position of the high bed, a first gear 71 is provided on the power shaft of the watering cart 1. The first gear 71 drives the second gear 72 to rotate. The second gear 72 drives the sleeve 73 and the internal gear ring 74 to rotate. When the trigger plate 610 rotates, the trigger plate 610 drives the telescopic rack 69 to move. The telescopic rack 69 drives the inclined block 79 to move. The inclined block 79 drives the extension rod 78 to move. The extension rod 78 drives the internal gear ring 74 to move, so that the internal gear ring 74 meshes with the third gear 75, thereby driving the third gear 75 to rotate. The third gear 75 drives the rotating shaft 510 to rotate through the transmission assembly 76, thereby driving the piston 42 to move downward, and the water is discharged from the water outlet pipe 43.

[0034] In specific use, the watering cart 1 is pushed to the high bed so that the high bed is located between the wheels of the watering cart. Then, the positions of the adjusting assembly 51 and the U-shaped plate 63 are adjusted respectively to adapt to the high bed. Then, the watering cart 1 moves. When it moves to the position of the high bed, the trigger plate 610 rotates. The trigger plate 610 drives the sealing plug 44 to rotate to open the water outlet pipe 43. The water flows out from the water outlet pipe 43 and then falls onto the high bed to water the seeds. At the same time, the rotating mechanism 7 drives the rotating shaft 510 to rotate. The rotating shaft 510 drives the piston 42 to move downward through the control mechanism 5. One end of the connecting pipe 41 and the water outlet pipe 43 are both located at the bottom surface of the metering box 4. When the piston 42 fits with the bottom surface of the metering box 4, the water no longer flows out. When the trigger plate 610 passes over a high bed, the trigger plate 610 resets. The sealing plug 44 resets and blocks the water outlet pipe 43. Then, the return spring 59 pushes the piston 42 upward. Under the gravity of the water in the water storage cylinder 2 and the suction of the upward movement of the piston 42, the water enters the metering box 4 from the water storage cylinder 2, thereby performing the next watering.

[0035] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they should all fall within the protection scope of the present invention.
