Description

Technical Field

[0001] The utility model relates to the field of agricultural instruments, in particular to a quantitative fertilization device for agricultural planting. Background Art

[0002] Fertilization is necessary in agricultural planting. Reasonable fertilization can improve the yield and quality of crops, and at the same time it is beneficial to improve soil fertility, thereby increasing the yield and economic benefits of crops. Fertilizers can be divided into three categories according to their state: solid fertilizers, liquid fertilizers and gaseous fertilizers. Common solid granular fertilizers include urea, ammonium sulfate, ammonium chloride and superphosphate.

[0003] When faced with some crops that are planted in small areas and carefully managed, there is often no suitable mechanical equipment. Fertilizer applicators often place granular fertilizers in buckets and then spread them. However, the uniform distribution of granular fertilizers during the fertilization process is a challenge. If they are unevenly distributed in the soil, it may cause over-fertilization of crops in some areas and lack of nutrients in other areas, thus affecting crop growth and yield. Utility Model Content

[0004] The utility model aims to provide a quantitative fertilization device for agricultural planting, which effectively solves the problem that when facing some small-area crops, artificial fertilization may cause uneven fertilization, resulting in over-fertilization or lack of fertilizer in some areas, affecting crop growth and yield.

[0005] The technical solution of the utility model is as follows:

[0006] A quantitative fertilization device for agricultural planting, comprising a fertilizer barrel, the fertilizer barrel is opened at the top and bottom, a material discharge box is arranged at the bottom of the fertilizer barrel, the vertical section of the material discharge box is semicircular, a circular material discharge port is arranged at the bottom of the material discharge box, a mounting plate is arranged at the periphery of the material discharge box, an arc groove is arranged inside the mounting plate, a movably connected conversion column is arranged inside the arc groove, and a through hole with a circular cross section is arranged inside the conversion column;

[0007] The outer wall of the fertilizer barrel is provided with a motor with an external power supply, the end of the output shaft of the motor is connected with a driving gear, the number of gear teeth on the driving gear accounts for half of the entire area of ​​the driving gear, the driving gear is meshed with a driven gear, the driven gear is provided with a positioning shaft connected to the fertilizer barrel, the positioning shaft is provided with a steering plate rotating around the circumference of the unloading box, the steering plate is provided with a second perforation, and when unloading, the centers of the discharge port, the first perforation, and the second perforation coincide.

[0008] Furthermore, a cover plate is provided on the top of the fertilizer barrel, the vertical section of the feed box is arc-shaped, a threaded ring is provided on the top of the feed box, and the feed box and the fertilizer barrel are connected by the threaded ring. The threaded connection can realize disassembly between the feed box and the fertilizer barrel, which is convenient for later cleaning.

[0009] Furthermore, the cross-section of the mounting plate is semicircular, and a sliding rod with a sliding connection is provided in the arc groove. One end of the sliding rod passes through the arc groove and is connected to the conversion column. The conversion column slides around the center of the mounting plate in the arc groove. The sliding rod is provided with a locking ring connected to the mounting plate. When adjusting different conversion columns, the perforation on the conversion column and the discharge port correspond to each other, and the conversion column is fixed by the locking ring.

[0010] Furthermore, a plurality of conversion columns are arranged in the arc-shaped groove, and the apertures of the perforations on each conversion column are different in size, so that the volume of fertilizer discharge can be changed by adjusting different conversion columns.

[0011] Furthermore, a handle is provided on the outer wall of the fertilizer barrel, a motor plate connected to the handle is provided, and the motor is mounted on the motor plate.

[0012] Furthermore, the vertical section of the steering plate is a cross semicircle, and the center of the semicircle of the steering plate coincides with the center of the semicircle of the feeding box. The bottom outer wall of the fertilizer barrel is provided with outwardly inclined supporting feet distributed in an annular manner.

[0013] The advantages of the utility model are:

[0014] 1. The utility model provides a feeding box at the bottom of the fertilizer barrel, and the fertilizer can flow out through the discharge port by sequentially passing through the perforation 1 in the conversion column and the perforation 2 in the steering plate. The steering plate is connected with a driven gear through a positioning shaft, and the number of gear teeth on the driving gear is only half. The gear teeth drive the steering plate to rotate in the process of cooperating with the driven gear. When all the gear teeth are rotated, the perforation 1 and the perforation 2 coincide with each other, so that the fertilizer flows out from the perforation 2, and the driving gear continues to rotate, but the steering plate remains stationary at this time. After the driving gear rotates one circle, it reverses. When it meshes with the driven gear again, the perforation 1 and the perforation 2 no longer coincide, and the steering plate prevents the feeding, thereby realizing quantitative fertilization of the fertilizer, avoiding the occurrence of unevenness in the process of manual fertilization, and being more efficient.

[0015] 2. The utility model sets a mounting plate on the material discharge box, and there is an arc groove in the mounting plate. A plurality of conversion columns are connected in the arc groove through a slide rod. The aperture size of the perforation 1 in each conversion column is inconsistent. By adjusting different conversion columns, the aperture size of the perforation 1 can be changed, and the flow rate of fertilizer passing through the perforation 1 can be changed, so that the driving gear can achieve quantitative fertilization of fertilizers of different volumes while keeping the complete quantitative fertilization time unchanged. Corresponding delivery can be achieved for crops with different needs, thereby improving the flexibility of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The outer wall of the fertilizer barrel 1 is provided with a motor 8 with an external power supply, and the end of the output shaft of the motor 8 is connected to a driving gear 9, the number of gear teeth on the driving gear 9 accounts for half of the area of ​​the entire driving gear 9, and the driving gear 9 is meshed with a driven gear 10, and the driven gear 10 is provided with a positioning shaft 11 connected to the fertilizer barrel 1, and the positioning shaft 11 is provided with a steering plate 12 rotating around the circumference of the unloading box 2, and the steering plate 12 is provided with a second perforation 13. When unloading, the centers of the discharge port 3, the first perforation 7, and the second perforation 13 coincide.

[0024] A cover plate 14 is provided on the top of the fertilizer barrel 1, the vertical section of the feed box 2 is arc-shaped, a threaded ring 15 is provided on the top of the feed box 2, and the feed box 2 and the fertilizer barrel 1 are connected via the threaded ring 15. The threaded connection allows the feed box 2 and the fertilizer barrel 1 to be disassembled, making later cleaning easier.

[0025] The mounting plate 4 has a semicircular cross-section, and a sliding rod 16 is provided in the arc groove 5 for sliding connection. One end of the sliding rod 16 passes through the arc groove 5 and is connected to the conversion column 6. The conversion column 6 slides around the center of the mounting plate 4 in the arc groove 5. A locking ring 17 connected to the mounting plate 4 is provided on the sliding rod 16. When different conversion columns 6 are adjusted, the through hole 7 on the conversion column 6 and the discharge port 3 correspond to each other, and the conversion column 6 is fixed by the locking ring 17.

[0026] There are multiple conversion columns 6 arranged in the arc groove 5, and the apertures of the through holes 7 on each conversion column 6 are different in size. The volume of fertilizer feeding can be changed by adjusting different conversion columns 6.

[0027] The outer wall of the fertilizer cylinder 1 is provided with a handle 18 , and a motor 8 plate connected to the handle 18 is provided, and the motor 8 is installed on a motor plate 19 .

[0028] The vertical section of the steering plate is a cross semicircle, and the semicircle center of the steering plate coincides with the semicircle center of the feeding box 2. The bottom outer wall of the fertilizer barrel 1 is provided with support feet 20 that are distributed in an annular manner and tilted outward.

[0029] Detailed usage and effects of the above embodiments:

[0030] When we need to apply fertilizer, add fertilizer from the top of the fertilizer barrel 1. There is a discharge box 2 at the bottom of the fertilizer barrel 1. The fertilizer will flow into the discharge box 2 and flow out from the discharge port 3 at the bottom of the discharge box 2. The perforation 17 on the conversion column 6 corresponds to the position of the discharge port 3. The fertilizer will flow down along the perforation 17. In the initial state, the fertilizer is blocked by the bottom steering plate 12 after flowing through the perforation 17, and the fertilizer will not flow out. The person lifts the fertilizer barrel 1 to a suitable fertilization position through the handle 18. The motor 8 is connected to a controller, and the motor 8 is operated by the controller to drive the driving gear 9 to rotate. When the driving gear 9 rotates, the gear teeth just mesh with the driven gear 10. The driven gear 10 rotates to drive the steering plate 12 on the positioning shaft 11 to rotate. When the gear teeth on the driving gear 9 and the driven gear 10 are fully meshed, the perforation 2 13 on the steering plate 12 just rotates to coincide with the center of the perforation 7, and the fertilizer flows out through the perforation 2 13.

[0031] The driving gear 9 continues to rotate, but at this time the driving gear 9 has no gear teeth meshing with the driven gear 10, so that when the driving gear 9 is rotating, the driven gear 10 does not rotate, and the steering plate 12 remains unchanged. After the driving gear 9 rotates one circle, the controller controls the motor 8 to reverse, and the gear teeth on the driving gear 9 mesh with the driven gear 10 again, so that the perforation 1 7 and the perforation 2 13 are misaligned, and the steering plate 12 closes the perforation 1 7, so that the fertilizer does not flow out, and the directional fertilization of the fertilizer is completed.

[0032] When we need to adjust the quantitative amount of fertilizer, a plurality of conversion columns 6 are connected to the mounting plate 4, and the aperture sizes of the through holes 7 on each conversion column 6 are inconsistent. Different conversion columns 6 are adjusted by the sliding rod 16 so that the through holes 7 with different apertures and the discharge port 3 correspond to each other. The fertilizer discharge amount can be changed by the different apertures on the conversion column 6 while the time for the driving gear 9 to rotate forward and reverse remains unchanged, so that flexible adjustments can be made for different crops.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
