DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: See Figure 1-5 The utility model provides a technical solution: a layered precision fertilizer spreader, which is mainly aimed at improving the problem that in the prior art, after the spacing of the fertilizer spreader is adjusted, the connection of the bellows is not conducive to the feeding operation of the fertilizer spreader, and it is easy to cause fertilizer blockage, which affects the fertilization efficiency of the fertilizer spreader. The specific scheme is as follows: it includes a pusher 100, a fertilizer assembly 5 and a support frame 1. The fertilizer assembly 5 is fixedly installed on the pusher 100 through a pin shaft. After the pusher 100 works, the fertilizer assembly 5 can be moved. A guide rod 2 is fixedly installed on one side of the support frame 1 corresponding to the fertilizer assembly 5, and the guide rod 2 is connected to the fertilizer assembly 5 through a limit screw 4; the upper end of the guide rod 2 is evenly provided with a limit hole 3, and the limit screw 4 is movably inserted into the limit hole 3. After the limit screw 4 is pulled out, the limit screw 4 can be replaced with different limit holes 3, so that the spacing between the fertilizer assemblies 5 can be adjusted, which is convenient for accurate layered processing of fertilizers and easy for the large-scale use of the fertilizer spreader.

[0025] See also Figure 1 and Figure 3 , wherein the fertilizer assembly 5 includes a fertilizer cylinder 51 and an end cap 52, the spacing between adjacent fertilizer cylinders 51 is equal, and the fertilizer cylinder 51 and the support frame 1 are arranged oppositely on both sides of the guide rod 2. The fertilizer cylinder 51 is slidably connected to the guide rod 2, and the center line of the fertilizer cylinder 51 and the guide rod 2 are perpendicular to each other. The fertilizer cylinder 51 and the end cap 52 are connected by threads, and the end cap 52 can facilitate the placement of fertilizers and prevent the volatilization of fertilizers.

[0026] Furthermore, a motor 50 is fixedly installed at the lower end of the end cover 52, and the motor 50 is connected to the control switch through a wire. A disturbance tooth 56 is provided on the output shaft of the motor 50, and a sliding sleeve 58 is provided above the disturbance tooth 56. A closed spiral groove 59 is provided inside the sliding sleeve 58, and a spiral block 591 is slidably connected inside the spiral groove 59. The spiral block 591 is fixedly installed on the output shaft of the motor 50, and the output shaft of the motor 50 and the center of the fertilizer barrel 51 are collinear. A toggle sleeve 57 is fixedly installed on the outside of the sliding sleeve 58, and scraping teeth are distributed in an annular manner on the outside of the toggle sleeve 57, and the scraping teeth are in contact with the fertilizer barrel 51; the toggle sleeve 57 is arranged inside the fertilizer barrel 51, and the toggle sleeve 57 and the center of the fertilizer barrel 51 are collinear. After the motor 50 is turned on, the spiral block 591 can rotate in a circular shape. Since the spiral block 591 always slides inside the spiral groove 59, during the circular movement of the spiral block 591, the sliding sleeve 58 can drive the toggle sleeve 57 to move up and down inside the fertilizer barrel 51, thereby cleaning the fertilizer on the side wall of the fertilizer barrel 51 to avoid fertilizer accumulation, further improving the fertilization effect of the fertilizer spreader; and a single motor 50 can achieve fertilizer disturbance and cleaning of the side wall of the fertilizer barrel 51, thereby improving resource utilization.

[0027] In this example, a soil hooking tooth 53 is fixedly installed at the lower end of the fertilizer barrel 51, and soil covering teeth 54 are symmetrically installed on both sides of the soil hooking tooth 53. A fertilizer outlet 55 is arranged inside the soil hooking tooth 53, and the fertilizer outlet 55 is connected to the inside of the fertilizer barrel 51. The soil hooking tooth 53 can hook the soil, so that the soil is turned to both sides, and at the same time, the fertilizer falls downward through the fertilizer outlet 55; and the soil covering teeth 54 arranged on both sides of the soil hooking tooth 53 can move the soil hooked out by the soil hooking tooth 53, so that the groove filled with fertilizer can be covered with soil.

[0028] Working principle: before the operation of this type of layered precision fertilizer spreader, the fertilizer is poured into the fertilizer barrel 51, and the end cover 52 is screwed on the top of the fertilizer barrel 51; under the pushing action of the pusher 100, the entire fertilizer assembly 5 moves, and the soil is hooked out by the hook soil teeth 53, so that the soil is turned to both sides, and at the same time, the fertilizer falls downward through the fertilizer outlet 55; and the covering soil teeth 54 arranged on both sides of the hook soil teeth 53 can move the soil hooked out by the hook soil teeth 53, so that the groove filled with fertilizer can be covered with soil; it is worth mentioning that after the motor 50 is turned on, the spiral block 591 can be made to rotate in a circular shape. Since the spiral block 591 always slides inside the spiral groove 59, during the circular movement of the spiral block 591, the sliding sleeve 58 can drive the toggle sleeve 57 to move up and down inside the fertilizer barrel 51, and then the fertilizer on the side wall of the fertilizer barrel 51 can be cleaned to avoid the accumulation of fertilizer, thereby further improving the fertilization effect of the fertilizer spreader.

[0029] 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.
