Description

Technical Field

[0001] This utility model relates to the field of irrigation device technology, and in particular to a quantitative broadcasting device for fertilizing tobacco fields. Background Technology

[0002] Tobacco cultivation is an agricultural production activity targeting Solanaceae crops such as red-flowered tobacco and yellow-flowered tobacco. It requires obtaining a "Tobacco Monopoly License" and signing a purchase contract with a tobacco company. The technical process includes site selection and land preparation, seedling raising and transplanting, field management, and harvesting and curing. It commonly employs mulching and "three-layer, one-deep" transplanting techniques. Since tobacco cultivation requires fertilization, fertilizer application devices are necessary.

[0003] Existing fertilization and sowing devices are equipped with mixing and filtering mechanisms that can accelerate the dissolution of granular fertilizers and filter the dissolved water-fertilizer mixture to prevent clogging of water pipes or damage to other components. However, the nozzles are often connected by long hoses, which are then used for irrigation. These long hoses have limited flexibility, are bulky, and have poor sealing at the joints, making them prone to leakage and resulting in waste. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides the following technical solution: a quantitative broadcasting device for tobacco field fertilization, comprising a base, an irrigation box fixedly connected to the upper end of the base, a pump body fixedly installed on the outside of the irrigation box, a pump body having a pumping pipe and an outlet pipe respectively provided on the pump body, the pumping pipe being slidably connected inside the irrigation box, and the outlet pipe having a connecting mechanism.

[0005] The connecting mechanism includes a threaded tube, which is threadedly connected to the outer side of the water outlet pipe. A pressure ring is fixedly connected to the inner wall of the threaded tube, and a sealing ring is adhered to the pressure ring. The sealing ring abuts against one end of the water outlet pipe and is slidably connected to the inner wall of the threaded tube. A bellows is fixedly connected to one end of the threaded tube, and a nozzle is provided on the bellows. A positioning block is fixedly connected to the outer side of the threaded tube, and a pin is slidably connected inside the positioning block. An installation block is fixedly connected to the outer side of the water outlet pipe, and a limit rod is fixedly connected inside the installation block. A spring is sleeved on the outer side of the limit rod.

[0006] As an improvement to the above technical solution, one end of the spring is fixedly connected to the pin, the other end of the spring is fixedly connected to the mounting block, the pin is slidably connected to the outside of the existing limiting rod, and the pin is slidably connected to the mounting block.

[0007] As an improvement to the above technical solution, the number of positioning blocks is several, and the several positioning blocks are distributed in a ring array on the outside of the threaded pipe. A through groove with the same diameter as the end of the pin is opened in the positioning block.

[0008] As an improvement to the above technical solution, the upper end of the irrigation box is connected to a cover plate by a thread, a motor is fixedly installed on the upper end of the cover plate, the output end of the motor is rotatably connected to the inside of the cover plate, a connecting shaft is fixedly connected to the output end of the motor, and a stirring frame is fixedly connected to the outside of the connecting shaft.

[0009] As an improvement to the above technical solution, a filter screen is slidably connected to the inner wall of the irrigation tank. A rotating shaft is mounted on the upper end of the filter screen via a bearing. An impeller is fixedly connected to the upper end of the rotating shaft. An elastic block is fixedly connected to the upper end of the filter screen. The elastic block works in conjunction with the impeller. A fixing block is fixedly connected to the inner wall of the irrigation tank. A magnetic block is attracted to the fixing block by magnetic force. The magnetic block is fixedly connected to the lower end of the filter screen. The filter screen abuts against the fixing block.

[0010] As an improvement to the above technical solution, a support rod is fixedly connected to the side of the base, a pusher is fixedly connected to the support rod, and a caster wheel is fixedly installed at the lower end of the base.

[0011] As an improvement to the above technical solution, a support plate is fixedly connected to the side of the base, and a screw is threadedly connected inside the support plate. One end of the screw is fitted with a ground plate through a bearing, and the other end of the screw is fixedly connected with a handle.

[0012] The beneficial effects of this utility model are as follows: the threaded pipe can be connected to the main body water outlet pipe. During the connection process by the thread, the pressure ring squeezes the sealing ring, causing the sealing ring to deform and improving the sealing performance. In addition, the spring drives the pin to be inserted into the positioning block, which can limit the threaded pipe and prevent the threaded pipe from loosening and causing the sealing performance to deteriorate. The corrugated pipe is fixedly connected to the threaded pipe. The corrugated pipe has good extensibility, which can reduce the volume and improve the space utilization rate.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please see Figure 1-6 This utility model provides a technical solution: a quantitative broadcasting device for fertilizing tobacco fields, including a base 1, an irrigation box 2 fixedly connected to the upper end of the base 1, a pump body 3 fixedly installed on the outside of the irrigation box 2, a water pumping pipe 4 and a water outlet pipe 5 respectively provided on the pump body 3, the water pumping pipe 4 being slidably connected inside the irrigation box 2, and a connecting mechanism 6 being provided on the water outlet pipe 5.

[0022] The connecting mechanism 6 includes a threaded pipe 61, which is threaded to the outer side of the water outlet pipe 5. A pressure ring 63 is fixedly connected to the inner wall of the threaded pipe 61, and a sealing ring 62 is adhered to the pressure ring 63. The sealing ring 62 abuts against one end of the water outlet pipe 5 and is slidably connected to the inner wall of the threaded pipe 61. A bellows 64 is fixedly connected to one end of the threaded pipe 61, and a nozzle 65 is provided on the bellows 64. A positioning block 66 is fixedly connected to the outer side of the threaded pipe 61, and a pin 67 is slidably connected inside the positioning block 66. The outer side of the water outlet pipe 5 is fixedly connected to... There is an installation block 68, and a limit rod 69 is fixedly connected inside the installation block 68. A spring 610 is sleeved on the outside of the limit rod 69. One end of the spring 610 is fixedly connected to the pin 67, and the other end of the spring 610 is fixedly connected inside the installation block 68. The pin 67 is slidably connected to the outside of the limit rod 69 and inside the installation block 68. There are several positioning blocks 66, which are arranged in a ring array on the outside of the threaded tube 61. A through groove with the same diameter as the end of the pin 67 is opened in the positioning block 66.

[0023] In this embodiment, the threaded pipe 61 can be rotated to create a threaded movement between it and the water outlet pipe 5. During this movement, the pressure ring 63 squeezes the sealing ring 62, causing it to deform, thereby improving the sealing performance at the connection between the threaded pipe 61 and the water outlet pipe 5. The corrugated pipe 64 fixed on the threaded pipe 61 has good extensibility, which can reduce the volume. Since the sealing ring 62 has a certain elasticity, the through groove on one of the positioning blocks 66 can be flush with the pin 67. At this time, under the elastic action of the spring 610, the pin 67 can move and slide into the positioning block 66, which can limit the threaded pipe 61 and prevent the threaded connection between the threaded pipe 61 and the water outlet pipe 5 from loosening and affecting the sealing performance. The pump body 3 can be started to draw water from the irrigation tank 2, which then flows through the water outlet pipe 5 and the corrugated pipe 64, and finally sprays out through the nozzle 65 for irrigation.

[0024] Specifically, the upper end of the pouring tank 2 is connected to a cover plate 7 by a thread. A motor 8 is fixedly installed on the upper end of the cover plate 7. The output end of the motor 8 is rotatably connected inside the cover plate 7. A connecting shaft 9 is fixedly connected to the output end of the motor 8. A mixing rack 10 is fixedly connected to the outside of the connecting shaft 9.

[0025] In this embodiment, the motor 8 can be started, which will cause the connecting shaft 9 fixed on the motor 8 to rotate. The connecting shaft 9 will drive the mixing frame 10 to rotate, which can stir the water and fertilizer in the irrigation tank 2 and make them evenly mixed.

[0026] Specifically, a filter screen 11 is slidably connected to the inner wall of the irrigation tank 2. A rotating shaft 12 is mounted on the upper end of the filter screen 11 via a bearing. An impeller 13 is fixedly connected to the upper end of the rotating shaft 12. An elastic block 14 is fixedly connected to the upper end of the filter screen 11. The elastic block 14 works in conjunction with the impeller 13. A fixing block 15 is fixedly connected to the inner wall of the irrigation tank 2. A magnetic block 16 is attracted by magnetic force inside the fixing block 15. The magnetic block 16 is fixedly connected to the lower end of the filter screen 11. The filter screen 11 abuts against the fixing block 15.

[0027] In this embodiment, the filter screen 11 can filter large particles to avoid clogging the nozzle 65. During the rapid rotation of the stirring frame 10, eddies are generated. At this time, the impeller 13 rotates and collides with the elastic block 14, causing the elastic block 14 to vibrate. This, in turn, causes the filter screen 11 connected to the elastic block 14 to vibrate, thus preventing the filter screen 11 from clogging. By moving the filter screen 11, the magnetic block 16 can be moved out of the fixing block 15, thereby releasing the filter screen 11 from the installation and making it easier to remove the filter screen 11 for more detailed cleaning.

[0028] Specifically, a support rod 17 is fixedly connected to the side of the base 1, a pusher 18 is fixedly connected to the support rod 17, a caster wheel 19 is fixedly installed at the lower end of the base 1, a support plate 20 is fixedly connected to the side of the base 1, a screw 21 is threadedly connected inside the support plate 20, a ground plate 22 is installed at one end of the screw 21 through a bearing, and a handle 23 is fixedly connected to the other end of the screw 21.

[0029] In this embodiment, the base 1 can be moved by pushing the pusher 18 and under the action of the caster wheel 19, which facilitates the movement of the device. After moving to a certain position, the screw 21 can be rotated to make it move threadedly with the support plate 20. At this time, the screw 21 drives the ground plate 22 to move and contact the ground, increasing the grounding area and preventing the device from moving easily after stopping in a certain place.

[0030] Working principle: The base 1 can be moved by pushing the pusher 18 and using the casters 19, facilitating the movement of the device. After moving to a certain position, the screw 21 can be rotated to create a threaded movement between it and the support plate 20. At this time, the screw 21 drives the grounding plate 22 to move and contact the ground, increasing the grounding area and preventing the device from easily moving after stopping in one place. Water and fertilizer are put into the irrigation tank 2, and then the motor 8 is started, which causes the connecting shaft 9 fixed on the motor 8 to rotate. The connecting shaft 9 drives the mixing frame 10 to rotate, which can stir the water and fertilizer in the irrigation tank 2 to make them evenly mixed. The filter screen 11 can filter large particles to prevent clogging of the nozzle 65. During the rapid rotation of the mixing frame 10, eddies are generated. At this time, the impeller 13 rotates and collides with the elastic block 14, causing the elastic block 14 to vibrate. This, in turn, causes the filter screen 11 connected to the elastic block 14 to vibrate, preventing the filter screen 11 from clogging. By moving the filter screen 11, the magnetic block 16 can be moved out of the fixing block 15, thus releasing the installation of the filter screen 11. The pump body 3 can then be started to draw water from the irrigation tank 2, which is then sprayed out through the water outlet pipe 5 and the corrugated pipe 64, and finally through the nozzle 65 for irrigation.

[0031] Rotating the threaded pipe 61 causes a threaded movement between it and the outlet pipe 5. During this movement, the pressure ring 63 compresses the sealing ring 62, causing it to deform and thus improving the sealing performance at the connection between the threaded pipe 61 and the outlet pipe 5. The bellows 64 fixed on the threaded pipe 61 has good extensibility and can reduce its volume. Since the sealing ring 62 has a certain elasticity, the through groove on one of the positioning blocks 66 can be flush with the pin 67. At this time, under the elastic action of the spring 610, the pin 67 can move and slide into the positioning block 66, which can limit the threaded pipe 61 and prevent the threaded connection between the threaded pipe 61 and the outlet pipe 5 from becoming loose and affecting the sealing performance.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
