Description

Technical Field

[0001] The invention relates to the technical field of agricultural side deep fertilization devices, in particular to an agricultural side deep fertilization device. Background Art

[0002] After the first season of harvest, regenerated rice can be fertilized and watered to provide nutrients for the second season of growth and harvest. Previous manual fertilization was time-consuming, labor-intensive, and inefficient. The agricultural side-deep fertilization device is fixed on the rear end beam of the mobile carrier. Through the movement of the carrier, the device can open a 4-5 cm deep trench 3-5 cm from the side of the rice pile, sprinkle fertilizer in the trench, and then cover it with soil. In this way, the agricultural side-deep fertilization device can accurately deliver fertilizer into the soil, thereby reducing fertilizer usage, improving fertilization efficiency, and avoiding waste and pollution caused by fertilizer exposure to the surface.

[0003] Existing agricultural side deep fertilization devices usually control the fertilizer output by the speed of the screw sleeve driven by a motor. However, due to the different sizes of fertilizer particles and the slight increase or decrease in the amount of material discharged by the screw sleeve each time, the final fertilizer output control is not precise enough.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a side deep fertilization device for agriculture is proposed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an agricultural side deep fertilization device, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an agricultural side deep fertilization device, comprising a mounting plate and a quantitative discharging assembly, a material barrel is fixed on one side of the side of the mounting plate, and a feed pipe is connected to the bottom of the material barrel, the quantitative discharging assembly is connected to the bottom end of the feed pipe, the quantitative discharging assembly comprises a pipe sleeve, a piston column, a quantitative opening, an electric telescopic rod, an adjusting plate, a gear rod, a transmission rod, a transmission turntable and a driving motor, a piston column is arranged inside the pipe sleeve, and a quantitative opening is opened in the middle of the side of the piston column, an electric telescopic rod is arranged in the upper inner wall of the piston column, and the bottom of the electric telescopic rod is connected to the adjusting plate, the top of the piston column is connected to the gear rod, and the top of the gear rod is rotatably connected to the transmission rod, the top of the transmission rod is rotatably connected to the transmission turntable, and the side of the transmission turntable is connected to the driving motor.

[0007] Furthermore, the outer opening structure of the regulating plate is matched with the inner opening structure of the quantitative opening, and the regulating plate is embedded in the bottom of the piston column.

[0008] Furthermore, the driving motor is fixedly connected to the mounting plate, and the pipe sleeve and the material barrel are fixedly connected to the mounting plate via a bracket.

[0009] Furthermore, a furrowing plowshare is provided on the bottom outer wall of the pipe sleeve, and arc-shaped covering plates are provided on both sides of the furrowing plowshare.

[0010] Furthermore, one side of the gear rod is meshedly connected with a feed acceleration component, and the feed acceleration component includes a transmission gear, a transmission shaft, a first wheel disc, a transmission belt and a second wheel disc. One side of the transmission gear is connected to the transmission shaft, and the first wheel disc is fixed to the outer wall of the transmission shaft. The surface of the first wheel disc is meshedly connected with the transmission belt, and the bottom inner wall of the transmission belt is meshedly connected with the second wheel disc.

[0011] Furthermore, the transmission shaft is rotatably connected to the mounting plate, and the second wheel is rotatably connected to the mounting plate via the shaft.

[0012] Furthermore, the feed acceleration assembly also includes a ratchet, and the side of the second wheel disc is connected to the ratchet.

[0013] Furthermore, the feed acceleration component also includes a pusher blade and a connecting shaft. The connecting shaft is passed through the side of the feed pipe, and the pusher blade is connected to one end of the connecting shaft located inside the feed pipe.

[0014] Furthermore, the feed acceleration assembly also includes a receiving turntable, a torsion spring tooth and a one-way limit block. The end of the connecting shaft away from the pushing fan blade is connected to the receiving turntable, and a torsion spring tooth is provided at the side edge of the receiving turntable, and a one-way limit block is provided on one side of the torsion spring tooth.

[0015] Furthermore, the torsion spring teeth are engaged and connected with the ratchet, and the torsion spring teeth are elastically connected with the receiving turntable.

[0016] The present invention provides an agricultural side deep fertilization device, which has the following beneficial effects: 1. The agricultural side-deep fertilization device has a piston column that rises and falls along the inside of the pipe sleeve, and the feeding pipe injects the fertilizer in the material barrel into the inside of the quantitative opening and fills it up. The adjustment plate is raised and lowered in advance by an electric telescopic rod to adjust the size of the quantitative opening, so as to adjust and determine the amount of fertilizer that can be accommodated in the quantitative opening each time. The adjustment plate has a weighing effect and can weigh the amount of fertilizer discharged each time. Based on the weight of the fertilizer, the adjustment plate can be raised and lowered for fine adjustment to ensure that the amount of fertilizer discharged each time is within a preset range, which is conducive to controlling the fertilizer discharged each time to be within the preset range, so as to greatly improve the accuracy of fertilizer output. The piston column is raised and lowered with the movement of the carrier to discharge the material. This discharge method is point-to-point discharge, that is, the lifting speed of the piston column is controlled by the output speed of the driving motor, and the distance between the rice piles is determined by cooperating with the positioning structure such as the distance measuring sensor, so that the quantitative fertilizer can be accurately buried on the side of each rice pile when the piston column descends each time, thereby saving fertilizer.

[0017] 2. In the agricultural side-deep fertilization device, when the gear rod rises, it drives the transmission gear to rotate the first wheel disc, so that the ratchet wheel rotates. At this time, the ratchet wheel applies force to the torsion spring clamping teeth to make the receiving turntable carry the connecting shaft to make the pusher blades rotate in the same direction. When the pusher blades rotate inside the conveying pipe, they can push the fertilizer being transmitted inside the conveying pipe to speed up the fertilizer transmission speed, so that the quantitative opening can quickly inject fertilizer during the rising process, avoiding the situation that the quantitative opening rises and falls quickly due to the excessive speed of the driving motor, so that the fertilizer inside it that is not full of the preset amount falls, resulting in insufficient amount of discharged fertilizer.

[0018] 3. In the agricultural side-deep fertilization device, when the gear rod descends, the ratchet wheel rotates in the opposite direction through transmission. At this time, the force direction of the torsion spring teeth is not restricted and they rotate due to the force, so that the torsion spring teeth are separated from the ratchet wheel. At this time, the ratchet wheel rotates but the receiving turntable does not rotate. Therefore, the pusher blade does not rotate during the descent of the piston rod, thereby preventing the inside of the feed pipe from being reversed and causing retreat.

DETAILED DESCRIPTION

[0021] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] like Figure 1-Figure 6 As shown, the present invention provides a technical solution: an agricultural side deep fertilization device, including a mounting plate 1 and a quantitative discharging component 4, a material barrel 2 is fixed on one side of the mounting plate 1, and a feeding pipe 3 is connected to the bottom of the material barrel 2, and the quantitative discharging component 4 is connected to the bottom end of the feeding pipe 3, and the quantitative discharging component 4 includes a pipe sleeve 401, a piston column 402, a quantitative opening 403, an electric telescopic rod 404, an adjustment plate 405, a gear rod 406, a transmission rod 407, a transmission turntable 408 and a driving motor 409, a piston column 402 is arranged inside the pipe sleeve 401, and a quantitative opening 403 is opened in the middle of the side of the piston column 402, an electric telescopic rod 404 is arranged in the upper inner wall of the piston column 402, and the electric The bottom of the movable telescopic rod 404 is connected with an adjustment plate 405, the top of the piston column 402 is connected with a gear rod 406, and the top of the gear rod 406 is rotatably connected with a transmission rod 407, the top of the transmission rod 407 is rotatably connected with a transmission turntable 408, and the side of the transmission turntable 408 is connected with a drive motor 409, the outer mouth structure of the adjustment plate 405 is adapted to the inner mouth structure of the quantitative opening 403, and the adjustment plate 405 is embedded in the bottom of the piston column 402, the drive motor 409 is fixedly connected to the mounting plate 1, and the pipe sleeve 401 and the barrel 2 are fixedly connected to the mounting plate 1 through a bracket, and a furrowing plowshare 5 is provided on the bottom outer wall of the pipe sleeve 401, and arc-shaped covering plates 6 are provided on both sides of the furrowing plowshare 5; The specific operation is as follows: the driving motor 409 drives the transmission turntable 408 to rotate and drives the gear rod 406 to move up and down along the inside of the tube sleeve 401 through the transmission rod 407, so that the piston column 402 moves up and down along the inside of the tube sleeve 401. When the piston column 402 rises, the quantitative opening 403 on its side gradually coincides with the outlet position at the bottom end of the feeding pipe 3. At this time, the feeding pipe 3 injects the fertilizer inside the barrel 2 into the quantitative opening 403 and fills it up. The adjustment plate 405 is raised and lowered in advance by the electric telescopic rod 404 to adjust the internal size of the quantitative opening 403, so as to achieve the adjustment and determination. The amount of fertilizer that can be contained in the quantitative opening 403 each time, and the adjustment plate 405 has a weighing effect and can weigh the amount of fertilizer discharged each time. Based on the weight of the fertilizer, the adjustment plate 405 can be raised and lowered for fine adjustment to ensure that the amount of fertilizer discharged each time is within the preset range. As the transmission turntable 408 rotates, the piston column 402 moves downward to carry the fertilizer in the quantitative opening 403 and extend out from the bottom end of the pipe sleeve 401, so that the quantitative opening 403 is exposed, so that the fertilizer is injected into the opened soil trench. During the descending process of the piston column 402, its upper outer wall closes the bottom end outlet of the delivery pipe 3; The furrowing plowshare 5 goes four to five centimeters deep into the soil as the vehicle moves to open a furrow one to two centimeters wide. After the fertilizer is injected into the furrow, the arc-shaped covering plate 6 pushes the soil on both sides of the furrow to close it to achieve a covering effect, thereby preventing the fertilizer from being exposed and contacting the outside world. Based on the above description, the piston column 402 is lifted and lowered along the inside of the pipe sleeve 401, and the feeding pipe 3 injects the fertilizer inside the material barrel 2 into the inside of the quantitative opening 403 and fills it. The adjusting plate 405 is lifted and lowered in advance by the electric telescopic rod 404 to adjust the internal size of the quantitative opening 403, so as to adjust and determine the amount of fertilizer that can be accommodated in the quantitative opening 403 each time, and the adjusting plate 405 has a weighing effect and can weigh the amount of fertilizer discharged each time. Based on the weight of the fertilizer, the adjusting plate 405 can be lifted and lowered for fine adjustment to ensure that the amount of fertilizer discharged each time is within the preset range, which is conducive to controlling the fertilizer discharged each time to be within the preset range, so as to greatly improve the accuracy of the fertilizer output, and the piston column 402 is lifted and lowered with the movement of the carrier to discharge the material. This discharge method is point-to-point discharge, that is, the lifting speed of the piston column 402 is controlled by the output speed of the driving motor 409, and the positioning structure such as the distance measuring sensor is used to determine the distance between the rice piles, so that the piston column 402 can accurately bury the quantitative fertilizer to the side of each rice pile each time it descends, thereby saving fertilizer.

[0023] like Figure 1-Figure 6 As shown, one side of the gear rod 406 is meshedly connected with a feed acceleration component 7, and the feed acceleration component 7 includes a transmission gear 701, a transmission shaft 702, a first wheel disc 703, a transmission belt 704 and a second wheel disc 705. One side of the transmission gear 701 is connected to the transmission shaft 702, and the outer wall of the transmission shaft 702 is fixed with the first wheel disc 703, the surface of the first wheel disc 703 is meshedly connected with the transmission belt 704, and the bottom inner wall of the transmission belt 704 is meshedly connected with the second wheel disc 705, the transmission shaft 702 is rotatably connected to the mounting plate 1, and the second wheel disc 705 is rotatably connected to the mounting plate 1 through the shaft, the feed acceleration component 7 also includes a ratchet 706, and the side of the second wheel disc 705 A ratchet wheel 706 is connected, the feeding acceleration component 7 also includes a pushing blade 707 and a connecting shaft 708. The side of the feeding pipe 3 is penetrated with a connecting shaft 708, and the end of the connecting shaft 708 located inside the feeding pipe 3 is connected with the pushing blade 707. The feeding acceleration component 7 also includes a receiving turntable 709, a torsion spring clamping tooth 710 and a one-way limit block 711. The end of the connecting shaft 708 away from the pushing blade 707 is connected to the receiving turntable 709, and the side edge of the receiving turntable 709 is provided with a torsion spring clamping tooth 710, and a one-way limit block 711 is provided on one side of the torsion spring clamping tooth 710. The torsion spring clamping tooth 710 is engaged and connected with the ratchet wheel 706, and the torsion spring clamping tooth 710 is elastically connected to the receiving turntable 709; The specific operation is as follows: when the gear rod 406 rises, it drives the transmission gear 701 to rotate the first wheel disc 703, and the first wheel disc 703 drives the second wheel disc 705 to rotate through the transmission belt 704, and the second wheel disc 705 therefore drives the ratchet wheel 706 to rotate. At this time, the rotation direction of the ratchet wheel 706 is engaged with the torsion spring clamping tooth 710, and the force direction of the torsion spring clamping tooth 710 is limited by the one-way limit block 711 and cannot rotate. Therefore, the ratchet wheel 706 applies force to the torsion spring clamping tooth 710 so that the receiving turntable 709 carries the connecting shaft 708 to make the pusher blade 707 rotate in the same direction. When the pusher blade 707 rotates inside the conveying pipe 3, it can push the fertilizer being transmitted inside it to speed up the fertilizer transmission speed, so that the quantitative opening 403 can quickly inject fertilizer during the rising process, and avoid the situation that the quantitative opening 403 is quickly raised and lowered due to the excessive rotation speed of the driving motor 409, so that the fertilizer inside it that is not full of the preset amount falls, resulting in insufficient amount of discharged fertilizer. When the gear rod 406 descends, the ratchet 706 rotates in the opposite direction through transmission. At this time, the force direction of the torsion spring tooth 710 is not restricted and it rotates due to the force, so that the torsion spring tooth 710 is separated from the ratchet 706. At this time, the ratchet 706 rotates but the receiving turntable 709 does not rotate. Therefore, the pushing fan blade 707 does not rotate during the descent of the piston column 402, thereby preventing the inside of the conveying pipe 3 from being reversed and causing retreat.

[0024] In summary, when the agricultural side deep fertilization device is used, the motor 409 is first driven to drive the transmission turntable 408 to rotate and drive the gear rod 406 to move up and down along the inside of the pipe sleeve 401 through the transmission rod 407, so that the piston column 402 is lifted and lowered along the inside of the pipe sleeve 401. When the piston column 402 rises, the quantitative opening 403 on its side gradually coincides with the outlet position at the bottom end of the feed pipe 3. At this time, the feed pipe 3 injects the fertilizer inside the barrel 2 into the quantitative opening 403 and fills it. The adjustment plate 405 is lifted and lowered in advance by the electric telescopic rod 404 to adjust the internal size of the quantitative opening 403, so that The amount of fertilizer that can be contained in the quantitative opening 403 is adjusted and determined each time, and the adjusting plate 405 has a weighing effect and can weigh the amount of fertilizer discharged each time. Based on the weight of the fertilizer, the adjusting plate 405 can be raised and lowered for fine adjustment to ensure that the amount of fertilizer discharged each time is within the preset range. As the transmission turntable 408 rotates, the piston column 402 moves downward to carry the fertilizer in the quantitative opening 403 and extend out from the bottom end of the pipe sleeve 401, so that the quantitative opening 403 is exposed, so that the fertilizer is injected into the opened soil trench. During the descending process of the piston column 402, its upper outer wall closes the bottom end outlet of the delivery pipe 3; The furrowing plowshare 5 goes four to five centimeters deep into the soil as the vehicle moves to open a furrow one to two centimeters wide. After the fertilizer is injected into the furrow, the arc-shaped covering plate 6 pushes the soil on both sides of the furrow to close it to achieve a covering effect, thereby preventing the fertilizer from being exposed and contacting the outside world. When the toothed rod 406 rises, it drives the transmission gear 701 to rotate the first wheel disc 703, and the first wheel disc 703 drives the second wheel disc 705 to rotate through the transmission belt 704, so that the second wheel disc 705 drives the ratchet wheel 706 to rotate. At this time, the rotation direction of the ratchet wheel 706 is engaged with the torsion spring clamping tooth 710, and the force direction of the torsion spring clamping tooth 710 is limited by the one-way limit block 711 and cannot rotate. Therefore, the ratchet wheel 706 applies force to the torsion spring clamping tooth 710 so that the receiving turntable 709 carries the connecting shaft 708 to make the pusher blade 707 rotate in the same direction. When the pusher blade 707 rotates inside the conveying pipe 3, it can push the fertilizer being transmitted inside it to speed up the fertilizer transmission speed, so that the quantitative opening 403 can quickly inject fertilizer during the rising process, and avoid the situation that the quantitative opening 403 is quickly raised and lowered due to the excessive rotation speed of the driving motor 409, so that the fertilizer inside it that is not full of the preset amount falls, resulting in insufficient amount of discharged fertilizer. When the gear rod 406 descends, the ratchet 706 rotates in the opposite direction through transmission. At this time, the force direction of the torsion spring tooth 710 is not restricted and it rotates due to the force, so that the torsion spring tooth 710 is separated from the ratchet 706. At this time, the ratchet 706 rotates but the receiving turntable 709 does not rotate. Therefore, the pushing fan blade 707 does not rotate during the descent of the piston column 402, thereby preventing the inside of the conveying pipe 3 from being reversed and causing retreat.
