DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-6 As shown, the utility model provides a whole-warehouse pesticide application device for grain storage protective agents, comprising a drug storage box 1 for containing inert powders, a box cover 9 being provided on the top of the drug storage box 1, and the drug storage box 1 being mounted on the horizontal frames on the front and rear sides of a grain conveyor 11 through a plurality of connecting mechanisms 2. The drug storage box 1 is in an inverted bucket-shaped structure for easy drug application, and a bottom box 3 extending downward is provided at the bottom thereof, as shown in FIG. Figure 5As shown, a plurality of evenly arranged medicine outlet holes 4 are provided on the bottom plate of the bottom box 3, and a plurality of mixing mechanisms 5 for contacting and dividing grain and medicine are provided at the bottom of the bottom box 3. The plurality of mixing mechanisms 5 are arranged in multiple groups along the front-to-back direction of the bottom box 3, and the mixing mechanisms 5 in the two adjacent groups on the left and right are staggered to improve the uniformity of mixing grain and medicine.

[0032] like Figure 3 As shown, there are four connecting mechanisms 2, which are respectively arranged at the four corners of the medicine storage box 1. Specifically, the connecting mechanism 2 includes a connecting seat 21 fixed to the horizontal frame on the front and rear sides of the grain feeder 11 and a support rod 22 vertically fixed to the outer wall of the medicine storage box 1. A sleeve 23 is fixed to the top of the connecting seat 21 and is slidably connected to the lower part of the support rod 22. A first fixing ring 24 is horizontally fixed to the support rod 22, and a first spring 25 is sleeved on the lower part of the support rod 22. The two ends of the first spring 25 are respectively fixed to the fixing ring 24 and the sleeve 23. When the medicine is discharged from the medicine outlet 4, since the connecting mechanism 2 is not fixedly connected to the grain feeder 11, under the action of the first spring 25, the medicine storage box 1 will vibrate with the vibration of the grain feeder 11 to prevent the medicine from being blocked in the discharge hole 4 and allowing it to spill onto the grain on the conveyor belt.

[0033] like Figure 4 As shown, the mixing mechanism 5 includes a mounting plate 51 and mixing teeth 52. The screw rods of the mixing teeth 52 are installed in the screw holes of the mounting plate 51. The bottom of the mixing teeth 52 is provided with a hook that bends in the direction of grain conveyance. A certain distance is left between the mixing teeth 52 and the top of the conveyor belt of the grain conveyor 11, so that the mixing teeth can be as close to the conveyor belt as possible under pressure without rubbing or contacting the conveyor belt. After the chemical is sprinkled on the grain, as the grain continues to move, the mixing teeth 52 contact the grain and pull it to the sides of the mixing teeth 52, so that the grain below covers the chemical powder on the surface of the grain above. When passing the next set of mixing teeth 52, the raised parts after mixing are pulled to the sides again. This step is repeated to achieve the goal of uniform mixing of the grain and chemical powder. Compared with traditional manual mixing methods, the mixing uniformity and mixing efficiency are greatly improved.

[0034] As an optimal technical solution of the present invention: a screw hole is provided on the mounting plate 51, and a screw rod threadedly connected to the screw hole is provided on the upper part of the mixing tooth 52. The mixing tooth 52 and the mounting plate 51 are threadedly connected, so that the mixing tooth 52 can be replaced separately when it is damaged, thereby reducing maintenance costs.

[0035] As an optimal technical solution of the present invention: a strip-shaped opening is opened on the side wall of the bottom box 3, and an adjustment plate 6 is slidably installed in the strip-shaped opening. The bottom of the adjustment plate 6 is fitted with the bottom wall of the bottom box 3. By adjusting the extension amount in the bottom box 3 to control the amount of medicine discharged from the medicine outlet 4, the amount of medicine used can be adjusted for different varieties or quantities of grains, thereby improving the scope of application.

[0036] As a preferred technical solution of the present invention, a locking mechanism 7 is provided on the bottom box 3. The locking mechanism 7 includes a fixing plate 71 fixed to the side wall of the bottom box 3. A locking rod 72 is slidably mounted on the fixing plate 71. A plurality of side holes 73 are provided on the side wall of the adjustment plate 6 for plugging into the locking rod 72. A second fixing ring 74 and a return spring 75 are provided on the locking rod 72. The second fixing ring 74 is coaxially fixed to the locking rod 72. The return spring 75 is sleeved on the locking rod 72, with its two ends respectively fixed to the second fixing ring 74 and the fixing plate 71. A pull plate 76 is provided on the end of the locking rod 72 away from the side hole 73. By inserting the locking rod 72 into the side hole 73 of the adjustment plate 6, the position of the adjustment plate 6 can be limited, preventing the adjustment plate 6 from sliding during the vibration of the bottom box 3, resulting in a change in the feeding amount. The return spring 75 can prevent the locking rod 72 from detaching from the side hole 73.

[0037] As a preferred technical solution of the present invention, the medicine storage box 1 is in an inverted bucket-shaped structure, and a plurality of reinforcing ribs 8 are provided between the two sides of the top to enhance the storage firmness of the medicine storage box 1 and meet the requirements of continuous storage of medicines and stability.

[0038] As a preferred technical solution of the present invention, both the box cover 9 and the adjustment plate 6 are provided with handles 10 , so that the staff can open and close the box cover 9 or pull the adjustment plate 6 .
