[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-6 A sample collection device for fertilizer production includes a storage box 1. A fixing plate 2 is fixedly mounted on the top of the storage box 1. A motor 3 is fixedly mounted on the outer wall of the fixing plate 2. A lead screw 4 is fixedly mounted on the output shaft of the motor 3. A movable seat 5 is provided on the outer wall of the lead screw 4. A through hole 16 is opened on the outer wall of the movable seat 5. An electric telescopic rod 6 is fixedly mounted on the top of the movable seat 5. A lifting frame 7 is fixedly mounted on the output shaft of the electric telescopic rod 6. A limit groove 10 is opened on the outer wall of the lifting frame. Motor 8 is fixedly mounted on the outer wall of 7. A lead screw 9 is fixedly mounted on the output shaft of motor 8. A movable plate 11 is threadedly connected to the outer wall of lead screw 9. An mounting plate 12 is fixedly mounted on the top of movable plate 11. A pump body 13 is fixedly mounted on the outer wall of mounting plate 12. A material extraction pipe 14 is connected to the inlet of pump body 13. A material valve 17 is provided on the inner wall of material extraction pipe 14. A discharge pipe 15 passes through the outer wall of material extraction pipe 14. A material valve 18 is provided at the connection between material extraction pipe 14 and discharge pipe 15.
[0025] In the above structure, the storage box 1, fixed plate 2, motor 3, lead screw 4, moving seat 5, electric telescopic rod 6, lifting frame 7, motor 8, lead screw 9, and limiting groove 10 are configured so that during use, the user can rotate the lead screw 4 by operating the motor 3, thereby moving the moving seat 5 along the top of the storage box 1 and allowing the pump body 13 to sample fertilizer from different locations inside the storage box 1. This ensures the uniformity and range of fertilizer sampling, thereby improving the sampling effect and automation of the device.
[0026] In a preferred embodiment, the pump body 13 is fixedly equipped with an exhaust pipe at its output port and a connecting pipe at its input port, and the input port of the pump body 13 is connected to the interior of the material extraction pipe 14 through the connecting pipe.
[0027] In the above structure, the pump body 13 and the extraction pipe 14 allow the device to operate so that the pump body 13 opens the material valve 17 inside the extraction pipe 14. When the material valve 18 is closed, the air inside the extraction pipe 14 is discharged, creating a negative pressure inside the extraction pipe 14 to extract the fertilizer from the storage tank 1. This allows the fertilizer to enter the extraction pipe 14. Finally, the material valve 17 closes and the material valve 18 opens, causing the fertilizer inside the extraction pipe 14 to be expelled through the discharge pipe 15. This achieves the effect of automatic fertilizer extraction and discharge, making it easier for users to extract samples and improving the practicality of the device.
[0028] In a preferred embodiment, the discharge pipe 15 is located 3cm above the lifting frame 7, and the outer wall of the lifting frame 7 is slidably connected to the inner wall of the limiting groove 10.
[0029] In the above structure, through the lifting frame 7 and the limiting groove 10, the user can lower the lifting frame 7 by retracting the output shaft of the electric telescopic rod 6, thereby adjusting the height of the extraction pipe 14. This allows for the extraction of fertilizer at different depths, making it easier for the user to sample fertilizer at different locations and further improving the sampling range of the device.
[0030] In a preferred embodiment, there are two movable seats 5, and both movable seats 5 are symmetrically distributed along the top of the storage box 1.
[0031] In the above structure, the two movable seats 5 are designed so that during operation, the user can move the movable seats 5 by operating the motor 3, thereby cooperating with the movement of the movable plate 11 to achieve the effect of adjusting the position of the material extraction tube 14 on both axes, thus improving the precision coordination of the components of the device.
[0032] In a preferred embodiment, the bottom of the movable seat 5 is slidably connected to the top of the storage box 1, and the inner wall of the through hole 16 is threadedly connected to the outer wall of the lead screw 4.
[0033] In the above structure, the through hole 16 ensures that the moving seat 5 can move normally during the rotation of the lead screw 4, thereby achieving the effect of automatically adjusting the position of the material extraction tube 14 and ensuring the normal operation of the device.
[0034] In a preferred embodiment, a controller and a synchronizer are fixedly mounted on the outer wall of the storage bin 1, and the controller is electrically connected to the synchronizer and the motor 3 respectively.
[0035] In the above structure, the synchronizer and controller structure allows the user to operate the two motors 3 synchronously through the controller and synchronizer during use, so that the two moving seats 5 can move synchronously and avoid the lifting frame 7 from tilting or even getting stuck, thereby ensuring the normal operation of the device.
[0036] In a preferred embodiment, the inner walls of both the storage tank 1 and the extraction pipe 14 are filled with fertilizer, and the extraction pipe 14 is made of galvanized iron.
[0037] In the above structure, galvanized iron has the characteristics of hardness and wear resistance, which can effectively reduce the wear of the extraction pipe 14 during operation and prevent the chemical substances in fertilizer from causing excessive corrosion to the extraction pipe 14 and affecting its service life. In addition, galvanized iron also has the characteristics of low cost, which reduces the production cost of the device.
[0038] In a preferred embodiment, a positioning plate is also fixedly mounted on the top of the storage box 1, and the outer wall of the positioning plate is rotatably connected to the end of the lead screw 4.
[0039] In the above structure, the positioning plate and lead screw 4 prevent the end of the lead screw 4 from shifting or becoming centrifugal during rotation, thus ensuring the stability of the lead screw 4 during rotation. This allows the moving seat 5 to reciprocate so that the extraction pipe 14 can extract fertilizer from different positions, thereby ensuring that the subsequent use of the device will not be affected.
[0040] Working Principle: After assembling the device, the user can first connect the production equipment to the storage tank 1, allowing the fertilizer product to be stored inside the storage tank 1. Then, the operation of motor 3 moves the moving base 5, causing the electric telescopic rod 6 to follow the moving base 5 and move the extraction pipe 14 laterally. The descent of the output shaft of the electric telescopic rod 6 allows the extraction pipe 14 to contact the fertilizer, thereby causing the pump body 13 to operate and expel the air inside the extraction pipe 14 to create negative pressure to extract the fertilizer. After sampling, the moving plate 11 can be moved to allow the extraction pipe 14 to sample fertilizer at different locations, thus improving the sampling range and automation of the device. After sampling, the material valve 17 is closed, and the material valve 18 is opened, along with the operation of the pump body 13, to discharge the fertilizer through the discharge pipe 15, thereby achieving automatic sampling and facilitating sample extraction for the user, thus improving the practicality of the device.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
