DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor fall within the scope of the utility model.

[0025] Please refer to Figures 1-6 The utility model provides a kind of technical scheme: a quantitative fertilizer injection device of bottoming, including fertilizer box 1.

[0026] Crushing assembly 2, crushing assembly 2 includes discharge pipe 201, the bottom of discharge pipe 201 is fixedly connected with horn mouth 202, the inner ring surface of horn mouth 202 is fixedly connected with first crushing strip 203, the directly below of horn mouth 202 is provided with conical cylinder 205, the side surface of conical cylinder 205 is fixedly connected with second crushing strip 204, the bottom of the side surface of conical cylinder 205 is fixedly connected with first transmission lever 206.

[0027] Transmission assembly 3, transmission assembly 3 includes connecting column 301, the inside of connecting column 301 is movably connected with rotating shaft 302, the side surface of one rotating shaft 302 is fixedly sleeved with first transmission wheel 303, the side surface of first transmission wheel 303 is transmissionally connected with transmission belt 304, the inner wall of the other end of transmission belt 304 is transmissionally connected with second transmission wheel 305, the inside of second transmission wheel 305 is fixedly sleeved with movable shaft 306, one end of movable shaft 306 is fixedly connected with transmission disc 307, the side surface of transmission disc 307 is fixedly connected with second transmission lever 308, the other end of movable shaft 306 is movably connected with support 309 through bearing.

[0028] Support assembly 4 includes a support rod 401. The other end of the support rod 401 is movably connected to a connector 402 via a bearing. The other end of the connector 402 is fixedly connected to the bottom of the fertilizer box 1. The other end of the support rod 401 is fixedly connected to the top inner wall of the cone 205.

[0029] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the top of the feeding pipe 201 is fixedly connected to the bottom of the fertilizer box 1, and the top of the connecting column 301 is fixedly connected to the bottom of the fertilizer box 1. In use, fertilizer is first added to the fertilizer box 1. The operator pushes the handle 5 to rotate the traveling wheel 6. Simultaneously, the second transmission wheel 305, the first transmission wheel 303, and the transmission belt 304 cause the second transmission lever 308 on the transmission disc 307 to drive the first transmission lever 206 and the cone 205 to rotate. When the cone 205 rotates, the second crushing bar 204 on the cone 205 and the first crushing bar 203 on the flared end 202 apply force to the clumped fertilizer, thereby crushing the clumped fertilizer and preventing it from clogging the outlet. Due to the cone at the top of the cone 205, the crushing chamber formed between the cone surface and the inner ring surface of the flared end 202... The opening is larger near the center and smaller towards the bottom edge, allowing clumps of fertilizer to effectively enter the crushing chamber. Under the weight of the clumps and the force of the first and second crushing bars 203 and 204, the clumps are effectively crushed, preventing them from clumping at the bottom. Through the crushing component 2 and the transmission component 3, the clumps of fertilizer are crushed simultaneously while the device is moving to apply fertilizer, thus improving fertilization efficiency. No secondary processing of the clumps is required, enhancing both efficiency and practicality. The crushing component 2 prevents clogging of the outlet during fertilization, ensuring consistent application and quantitative fertilization. It also prevents clumps from falling and causing localized burning of seedlings, resulting in more even fertilizer distribution.

[0030] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, multiple first crushing bars 203 are arranged in a ring array with the center of the flared mouth 202, and multiple second crushing bars 204 are arranged in a ring array with the center of the cone 205.

[0033] In this embodiment, as shown in Figure 2 , Figure 3 and Figure 4 , the side surface of the fertilizer box 1 is fixedly connected with a handle 5, and the fertilizer box 1 is used to hold fertilizer.

[0034] In this embodiment, as shown in Figure 2 , Figure 3 and Figure 4 , the inner annular surface of the horn mouth 202 and the top conical surface of the conical cylinder 205 form a grinding cavity, and the opening near the center of the grinding cavity is larger than the opening away from the center.

[0035] The use method and advantages of the present application are as follows:

[0036] As shown in Figure 2 , Figure 3 , Figure 4 , Figure 1 , Figure 2 and Figure 3 Figure 4 Figure 5 Figure 6 , when in use, first put the fertilizer into the fertilizer box 1, and then push the handle 5 to make the walking wheels 6 rotate, while the walking wheels 6 rotate, the second transmission rod 308 on the transmission disc 307 drives the first transmission rod 206 and the conical cylinder 205 to rotate through the second transmission wheel 305, the first transmission wheel 303 and the transmission belt 304, when the conical cylinder 205 rotates, the second crushing strip 204 on the conical cylinder 205 and the first crushing strip 203 on the horn mouth 202 exert force on the caked fertilizer, so that the caked fertilizer is crushed, and the caked fertilizer is prevented from blocking the discharge port, because of the cone on the top of the conical cylinder 205, the crushing cavity formed between the conical surface and the inner annular surface of the horn mouth 202 has a larger opening near the center and a smaller opening at the bottom edge, so that the caked fertilizer can effectively enter the crushing cavity, and under the action of gravity of the caked fertilizer and the force of the first crushing strip 203 and the second crushing strip 204, the caked fertilizer is effectively crushed to prevent the phenomenon of caking.
