Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, specifically to a variable fertilization device for cotton based on soil moisture. Background Technology

[0002] The cotton variable fertilization device based on soil moisture is an intelligent agricultural device that combines soil moisture monitoring technology with precision fertilization control. Its core function is to dynamically adjust the amount of fertilizer, the timing of fertilization, or the fertilizer ratio according to the differences in soil moisture in different locations within the cotton planting area, so as to achieve on-demand fertilization, thereby improving fertilizer utilization, reducing resource waste, and promoting cotton growth.

[0003] In the prior art, a dual-variable fertilization device for cotton planting, with patent publication number CN213462981U, includes a cylinder, a first threaded pipe, a first valve, an internal threaded pipe, a second threaded pipe, a feed pipe, a mounting plate, a motor, a first rotating shaft, a spiral stirring blade, a storage battery, a first traveling wheel, a discharge pipe, a second valve, a third threaded pipe, and a hose; two first threaded pipes are connected through the upper side of the cylinder's annular wall.

[0004] When switching between different fertilizers, the device usually requires manually opening and closing the valves on both sides one by one. This switching method is prone to human error, resulting in the two valves opening at the same time or not closing completely. If the two valves are opened at the same time, the two fertilizers may be mixed prematurely, affecting the accuracy of the fertilizer ratio. If the valves are not closed completely, fertilizer leakage or waste may occur, thus affecting the fertilization effect. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] The present invention will be further described below with reference to the embodiments.

[0033] Example: A variable fertilization device for cotton based on soil moisture, see attached document. Figure 1 -Appendix Figure 7 ,include,

[0034] The fertilizer application device body 100 includes a spiral feeding pipe 110, an inlet pipe 120 and an outlet valve 130 respectively connected to the upper and lower sides of the spiral feeding pipe 110, a motor 140 adapted to be installed on the outside of the spiral feeding pipe 110, and a moving trolley 150 located at the bottom of the spiral feeding pipe 110.

[0035] It should be noted that the spiral feeding pipe 110 is the core channel for fertilizer mixing and conveying. The motor 140 drives the internal spiral rod to convey fertilizer. The feed pipe 120 has two channels, which are used to inject liquid fertilizer and solid fertilizer respectively. The connection and disconnection with the spiral feeding pipe 110 are controlled by the baffle plate 219. The discharge valve 130 is used to control the discharge of the mixed fertilizer. The motor 140 is used to provide power for the conveying of fertilizer in the spiral feeding pipe 110. The mobile trolley 150 is used to carry the entire fertilizer applicator body 100, which is convenient for its movement in cotton fields. The fertilizer applicator body 100 is existing technology and will not be described in detail in this solution. Moreover, those skilled in the art can clearly understand its working principle.

[0036] Two feed pipes 120 are provided, which are used to inject liquid waste and solid waste into the spiral feed pipe 110 respectively;

[0037] The feeding assembly 200 includes a connecting assembly 210 for controlling the connection between any feed pipe 120 and the spiral feeding pipe 110, a switching assembly 220 that can automatically lock the position of the connecting assembly 210 when any feed pipe 120 is connected to the spiral feeding pipe 110, and an unlocking assembly 230 for releasing the connection between any feed pipe 120 and the spiral feeding pipe 110.

[0038] Two sets of connecting components 210 are provided, which are located on the outside of the feed pipe 120;

[0039] Both the switching component 220 and the unlocking component 230 are located inside the connecting component 210;

[0040] The connecting component 210 includes a fixed frame 211 fixedly connected to the outside of the spiral feed tube 110, a first push rod 212 slidably connected to the inner surfaces of both sides of the fixed frame 211, and a rack 213 fixedly connected to the through end of the first push rod 212.

[0041] Specifically, the connecting component 210 also includes a spur gear 214 meshing with the outer surface of the rack 213, a support column 215 fixedly connected to the inner surface of the spur gear 214, a first bevel gear 216 fixedly sleeved on the outer surface of the support column 215, a second bevel gear 217 meshing with the outer surface of the first bevel gear 216, a rotating rod 218 fixedly connected to the inner surface of the second bevel gear 217, and a baffle 219 fixedly installed at the through end of the rotating rod 218.

[0042] It should be noted that when the first push rod 212 is pushed, it can drive the spur gear 214 to move, so that the spur gear 214 drives the first bevel gear 216 and the second bevel gear 217 to rotate synchronously through the support column 215. Then, through the cooperation of the second bevel gear 217 and the rotating rod 218, the baffle 219 is driven to rotate, thereby releasing the blockage of the feed pipe 120.

[0043] Furthermore, the outer end face of the support column 215 is fixedly mounted on the outer surface of the spiral feed pipe 110 by bearings, and a rotating bearing sleeve is installed at the connection between the rotating rod 218 and the feed pipe 120.

[0044] Preferably, the switching assembly 220 includes a first force-applying column 221 fixedly connected to the inner surface of the first push rod 212, a sliding plate 222 slidably connected to the inner wall of the fixed frame 211, and a first force-receiving groove 223 and a positioning groove 224 respectively opened on both sides of the sliding plate 222 and used in conjunction with the first force-applying column 221.

[0045] It should be noted that the switching assembly 220 also includes a fixed post 225 fixedly connected to the inner wall of the fixed frame 211, a first spring 226 fixedly installed on the outer surface of the fixed post 225, a slide groove 227 opened on the surface of the sliding plate 222 and used in conjunction with the positioning groove 224, and a second spring 228 sleeved on the outside of the first push rod 212.

[0046] It should also be noted that when the first push rod 212 is pushed, it can cause the first force-applying column 221 to squeeze the first force-receiving groove 223, causing the sliding plate 222 to slide along the fixed frame 211. When the first force-applying column 221 moves to the position where it is no longer in contact with the first force-receiving groove 223, the second spring 228 drives the sliding plate 222 to reset through the reaction force, so that the sliding plate 222 limits the first force-applying column 221 through the positioning groove 224.

[0047] Furthermore, the outer surface of the first force-applying column 221 is slidably connected to the inner surface of the fixed frame 211, the outer surface of the positioning groove 224 is slidably in contact with the inner wall of the sliding groove 227, the outer end face of the fixed column 225 is fixedly connected to the outer surface of the sliding plate 222, and the second spring 228 is fixedly installed on the outer surface of the first push rod 212, with its other end fixedly connected to the inner wall of the fixed frame 211.

[0048] Specifically, the unlocking component 230 includes a second push rod 231 slidably connected to the inner surface of the fixed frame 211 on the side away from the first push rod 212, a second force-applying column 232 fixedly connected to the inner surface of the second push rod 231, a second force-receiving groove 233 opened on the surface of the sliding plate 222 and used in conjunction with the second force-applying column 232, and a third spring 234 sleeved on the outside of the second push rod 231.

[0049] It should be explained that when the first push rod 212 is pushed, it can cause the first force-applying column 221 to squeeze the first force-receiving groove 223, causing the sliding plate 222 to slide along the fixed frame 211. This causes the sliding plate 222 to move the second force-receiving groove 233 to a position where it is no longer in contact with the second force-applying column 232. At this time, the reaction force of the second spring 228 drives the first push rod 212 and the first force-applying column 221 to reset, thereby releasing the limitation on the first push rod 212 and the first force-applying column 221.

[0050] Preferably, the outer surface of the second force-applying column 232 is slidably connected to the inner surface of the fixed frame 211, and the third spring 234 is fixedly installed on the outer surface of the second push rod 231, with its other end fixedly connected to the inner wall of the fixed frame 211.

[0051] When using,

[0052] Pushing the first push rod 212 corresponding to the feed pipe 120 drives the rack 213 to move synchronously, so that the rack 213 drives the gear 214, the support column 215 and the first bevel gear 216 to rotate synchronously. Through the cooperation of the first bevel gear 216 and the second bevel gear 217, the rotating rod 218 is driven to rotate, and then the rotating rod 218 drives the baffle 219 to rotate, so as to release the blockage of the feed pipe 120.

[0053] At the same time, the first push rod 212 drives the first force-applying column 221 to press the first force-receiving groove 223 on the inner side of the sliding plate 222, thereby causing the sliding plate 222 to slide along the inner wall of the fixed frame 211, and simultaneously compressing the first spring 226 and the second spring 228. When the first force-applying column 221 moves to the position of disengaging from the first force-receiving groove 223, the sliding plate 222 is driven to reset by the reaction force of the first spring 226, so that the sliding plate 222 drives the positioning groove 224 to lock the first force-applying column 221, thus completing the locking of the first force-applying column 221.

[0054] At this time, the fertilizer enters the screw feeding pipe 110 through the feed pipe 120, and is conveyed by the screw structure driven by the motor 140, so that the waste is discharged through the discharge valve 130, and then moved by the mobile trolley 150 carrying device.

[0055] When switching fertilizers: push the first push rod 212 of the other corresponding feed pipe 120, which will cause the other first force-applying column 221 to squeeze the other first force-receiving groove 223 on the inner side of the sliding plate 222, so that the sliding plate 222 slides along the inner wall of the fixed frame 211, and the other first force-receiving groove 223 is inserted into the other positioning groove 224. At the same time, the sliding plate 222 causes the corresponding positioning groove 224 to disengage from the first force-applying column 221. Then, the reaction force of the second spring 228 drives the corresponding first force-applying column 221 and the connecting component 210 to reset. Thus, the feed pipe 120 that is discharging material can be closed at the same time as the other feed pipe 120 is opened.

[0056] After fertilization is completed: the second push rod 231 is pushed to drive the second force column 232 to squeeze the second force groove 233 of the sliding plate 222, so that the sliding plate 222 slides and drives the positioning groove 224 to the position of disengaging from the first force column 221. Then, the reaction force of the second spring 228 drives the first push rod 212 to reset, so that the baffle 219 rotates to block the feed pipe 120. Then, the third spring 234 resets the second push rod 231.

[0057] In summary, by setting the feeding component 200, it is possible not only to automatically block the connection between the other set of feeding pipes 120 and the spiral feeding pipe 110 when any feeding pipe 120 is connected to the spiral feeding pipe 110 during fertilizer switching, thus preventing the simultaneous opening of both channels, but also to simultaneously block the connection between the two feeding pipes 120 and the spiral feeding pipe 110 after fertilization without the need for manual operation, thereby ensuring the accuracy of fertilizer switching during fertilization while improving the efficiency of variable fertilization.

[0058] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
