[0027] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0028] like Figures 1 to 3 As shown, this embodiment provides a fertilizer hopper of a fertilizer spreader and a fertilizer spreader, including a hopper 1 and a fixing frame 101 arranged on one side of the top of the hopper 1, and also includes:

[0029] A protection component, the protection component includes a cylinder 2 arranged on the top of the fixing frame 101, a piston rod 201 arranged at the output end of the cylinder 2, a slide bar 3 arranged at the bottom of the piston rod 201, and a protection cover 4 arranged at the bottom of the slide bar 3;

[0030] A liquid outlet component is arranged between the hopper 1 and the slide bar 3, and can squeeze out the fertilizer solution in the hopper 1 when the protective cover 4 moves downward;

[0031] The mixing assembly includes a screw rod 9 rotatably arranged on the inner bottom wall of the hopper 1, a first mixing plate 10 arranged on the outer wall of the screw rod 9, a pressure rod 5 slidably arranged on the top of the hopper 1, and a pressure sleeve 8 arranged at one end of the pressure rod 5 located inside the hopper 1, wherein a spiral groove matching the screw rod 9 is arranged inside the pressure sleeve 8, and the end of the pressure rod 5 away from the hopper 1 is connected to the rod wall of the sliding rod 3;

[0032] First, install the hopper 1 on the fertilizer machine, and then put the prepared fertilizer into the hopper 1 through the feed port installed on the back of the hopper 1 for mixing. When it is necessary to fertilize the seedlings in the farmland, first start the cylinder 2 to drive the slide bar 3 to move downward through the piston rod 201, so that the protective cover 4 at the bottom of the slide bar 3 contacts the soil and covers the seedlings. When the slide bar 3 moves downward, it will also drive the liquid outlet component to press out the fertilizer solution in the hopper 1 and spray it on the soil around the protective cover 4 for the seedlings to absorb, so the fertilizer will not be directly sprayed. The fertilizer solution in the hopper 1 is stirred by the first mixing plate 10 on the outer wall of the spiral rod 9, so that the solution can be stirred once each time the fertilizer solution is sprayed, and the solution is kept in a uniformly mixed state, avoiding the problem of fertilizer precipitation, so that the seedlings can be better absorbed.

[0033] Among them, the outer wall of the protective cover 4 is provided with a number of equally spaced guide grooves; part of the fertilizer solution will fall onto the outer surface of the protective cover 4 when sprayed out, and the guide grooves can make the fertilizer solution attached to the outer wall of the protective cover 4 easily slide into the soil, further keeping the surface of the protective cover 4 clean and tidy and avoiding waste.

[0034] In addition, a support plate 16 is provided at the bottom of the hopper 1, and a positioning plate 1601 is provided on the side wall of the support plate 16. A fixing bolt is threadedly connected to the surface of the positioning plate 1601; through the cooperation of the positioning plate 1601 and the fixing bolt, the hopper 1 can be easily installed on the fertilizer machine for use.

[0035] like Figure 1 , Figure 2 and Figure 4As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the liquid outlet assembly includes a pressing plate 501 slidably arranged on the inner wall of the hopper 1, a connecting sleeve 6 sleeved on the rod wall of the sliding rod 3, a plurality of spray heads 601 equidistantly arranged on the outer wall of the connecting sleeve 6, and a connecting pipe 7 arranged between the connecting sleeve 6 and the hopper 1, the pressing plate 501 is also fixedly connected to the pressing rod 5, a water storage chamber 602 is arranged inside the connecting sleeve 6, and a water inlet 603 and a water outlet 604 for connecting the connecting pipe 7 and the spray head 601 are arranged on the side wall of the connecting sleeve 6;

[0036] A one-way valve 102 and an observation window 103 are provided on the side wall of the hopper 1 near the top;

[0037] When injecting fertilizer into the hopper 1, the injection amount of the fertilizer solution can be viewed through the observation window 103, and the solution height can be made to be flush with the observation window 103. When the cylinder 2 drives the slide bar 3 to move downward, the pressure rod 5 will also drive the pressing plate 501 to move downward. The solution can be pressed into the connecting sleeve 6 through the connecting pipe 7 through the pressing plate 501, and then sprayed into the soil through the spray head 601 on the outer wall of the connecting sleeve 6. Then, the cylinder 2 is controlled to drive the protective cover 4 to move up and away from the soil, and the fertilization operation on other seedlings is continued. The one-way valve 102 is set to enable the pressing plate 501 moving up and down to continuously squeeze out the solution in the hopper 1.

[0038] like Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a U-shaped frame 11 is provided on the side wall of the pressing sleeve 8, a rotating rod 12 is rotatably connected to the side wall of the U-shaped frame 11, and a plurality of second mixing plates 14 equidistantly distributed are provided on the rod wall of the rotating rod 12;

[0039] The rod wall of the rotating rod 12 located inside the U-shaped frame 11 is fixedly connected with a gear 13, and the inner wall of the hopper 1 is provided with a toothed plate 15 meshing with the gear 13;

[0040] When the pressing sleeve 8 moves downward, it will also drive the gear 13 on the inner side of the U-shaped frame 11 to roll against the surface of the tooth plate 15, thereby driving the second mixing plate 14 on the rotating rod 12 to flip up and down inside the hopper 1, so that the fertilizer solution can be further stirred and mixed during the fertilization process, thereby improving the mixing effect of the fertilizer solution.

[0041] It should be noted that the surfaces of the first mixing plate 10 and the second mixing plate 14 are both provided with evenly distributed slots; when the first mixing plate 10 and the second mixing plate 14 rotate inside the hopper 1, the fertilizer solution will be pressurized and quickly pass through the slots, thereby increasing the flow rate of the solution, thereby further improving the solution mixing effect.

[0042] like Figure 1As shown, a fertilizer spreader includes the above-mentioned fertilizer hopper. The hopper 1 is installed on the fertilizer spreader, and then the fertilizer spreader is controlled to move in the farmland, so that the seedlings in various positions can be fertilized conveniently.

[0043] The working principle of the utility model is as follows: first, the hopper 1 is installed on the fertilizer machine, and then the prepared fertilizer is put into the hopper 1 through the feed port installed on the back of the hopper 1 for mixing. When it is necessary to fertilize the seedlings in the farmland, the cylinder 2 is started to work first, and the piston rod 201 drives the slide bar 3 to move downward, so that the protective cover 4 at the bottom of the slide bar 3 contacts the soil and covers the seedlings. When the slide bar 3 moves downward, it also drives the pressure rod 5 and the pressure plate 501 to move downward. Through the pressure plate 501, the solution can be pressed into the connecting sleeve 6 through the connecting pipe 7, and then sprayed to the surrounding of the protective cover 4 through the spray head 601. The fertilizer in the soil is used for seedling absorption, so the fertilizer will not be sprayed directly onto the seedlings, avoiding the seedlings from contacting a large amount of fertilizer and causing death; and the downward sliding rod 3 will also drive the pressing sleeve 8 to move downward through the pressing rod 5, and the pressing sleeve 8 will move downward on the outer wall of the spiral rod 9 and drive the spiral rod 9 to rotate. At this time, the spiral rod 9 will stir the fertilizer solution in the hopper 1 through the first mixing plate 10 on its outer wall, so that the solution can be stirred once each time the fertilizer solution is sprayed, keeping the solution in a uniformly mixed state, avoiding the problem of fertilizer precipitation, so that the seedlings can absorb it better.

[0044] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
