[0029] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0030] like Figure 1-4 As shown, an automatic fertilizer supply device for plants includes a supply box 1, an inlet 11 is provided on the upper side of the supply box 1, and a discharge port 12 is provided on the lower side, the discharge port 12 is slidably and sealedly connected to a sealing portion 13, the lower portion of the sealing portion 13 is cylindrical, and the upper cross-section of the sealing portion 13 is an isosceles trapezoid that is narrow on the upper part and wide on the lower part, a connecting shaft 14 is connected above the sealing portion 13, a guide cylinder 15 is fixedly connected to the outer side of the discharge port 12, an upper and lower reciprocating mechanism 2 is assembled and connected above the connecting shaft 14, a roller 3 is assembled and connected to the lower side of the supply box 1, and a push handle 4 is fixedly connected to one side of the supply box 1.

[0031] According to the technical solution of this embodiment, the supply box 1 is used to place fertilizers. The fertilizer 11 enters from the feed port 11 and is discharged from the discharge port 12. When the sealing part 13 contacts the discharge port 12, the fertilizer cannot be discharged. When the sealing part 13 moves up and down and separates from the discharge port 12, the fertilizer is discharged from the discharge port. The upper and lower reciprocating mechanism 2 is used to drive the sealing part 13 to move up and down, the roller 3 is used to move the supply box 1 with less effort, and at the same time, the discharge port 12 is not in contact with the ground, and the push handle 4 is used to facilitate the pushing of the supply box 1; when the connecting shaft 14 moves downward, the discharge port 12 discharges materials, so that the discharge port 12 discharges materials according to the speed interval of the reciprocating mechanism 2. When the supply box 1 is pushed to move, the discharge port 12 moves a certain distance and then discharges materials again while the walking speed of the staff remains unchanged.

[0032] Reference Figure 2-3 : The up and down reciprocating mechanism 2 includes a movable plate 201 rotatably connected to the upper end of the connecting shaft 14, a spring 202 is provided between the movable plate 201 and the upper side of the supply box 1, the connecting shaft 14 is fixedly connected to a positioning ring 203 on the lower side of the supply box 1, an eccentric wheel 204 is slidably connected to the upper side of the movable plate 201, the eccentric wheel 204 is transmission-connected to a first transmission shaft 205, the first transmission shaft 205 is assembled and connected to the supply box 1, and one end of the first transmission shaft 205 is transmission-connected to a motor 206.

[0033] The first transmission shaft 205 drives the eccentric wheel 204 to rotate, and the motor 206 drives the first transmission shaft 205 to rotate. The rotation of the motor 206 is controlled by the program, and the interval time between two adjacent unloading times can be controlled by controlling the rotation speed of the motor 206. Because the eccentric wheel 204 abuts against the moving plate 201, the rotation of the moving plate 201 is restricted. Since the moving plate 201 is rotationally connected to the connecting shaft 14, the connecting shaft 14 can rotate independently, and the rotation of the connecting shaft 14 will not be restricted by the eccentric wheel 204.

[0034] Reference Figure 4 : The connecting shaft 14 located inside the supply box 1 is evenly and fixedly connected to a plurality of stirring rods 5, and the connecting shaft 14 located outside the supply box 1 is transmission-connected to a rotating mechanism 6.

[0035] In this embodiment, the stirring rod 5 is used to stir the fertilizer to prevent the fertilizer from clumping, so that there will be no blockage when discharging the fertilizer, and the discharge is uniform. The rotating mechanism 6 is used to drive the connecting shaft 14 to rotate, and the connecting shaft 14 drives the stirring rod 5 to rotate.

[0036] Reference Figure 2-4 : The rotating mechanism 6 includes two matching bevel gears 601, a second transmission shaft 602, a driving tooth 603 and a driven tooth 604, one bevel gear 601 is transmission-connected to one side of the first transmission shaft 205, the other bevel gear 601 is transmission-connected to the second transmission shaft 602, the driving tooth 603 is rotationally connected to the second transmission shaft 602, the driven tooth 604 is meshingly transmission-connected to the driving tooth 603, the driven tooth 604 is fixedly assembled and connected to the connecting shaft 14, the thickness of the driving tooth 603 is greater than that of the driven tooth 604, and the upper part of the spring 202 is slidingly connected to the lower side of the driven tooth 604.

[0037] In this embodiment, the bevel gear 601 is used for reversing transmission, which transmits the power of the first transmission shaft 205 to the second transmission shaft 602. The second transmission shaft 602 drives the active tooth 603 to rotate, and the active tooth 603 drives the driven tooth 604 to rotate. The driven tooth 604 drives the connecting shaft 14 to rotate. Since the connecting shaft 14 is rotationally connected to the movable plate 201, the connecting shaft 14 will not drive the movable plate 201 to rotate. Because the thickness of the active tooth 603 is greater than that of the driven tooth 604, when the active tooth 603 slides downward, the active tooth 603 and the driven tooth 604 remain engaged, and when the connecting shaft 14 moves downward, they can rotate at the same time.

[0038] Reference Figure 3 : The guide tube 15 is cylindrical at the top and conical at the bottom.

[0039] In this embodiment, when the sealing portion 13 and the discharge port 12 are misaligned, the fertilizer flows out from the annular gap between the sealing portion 13 and the discharge port 12, and the guide tube 15 is used to concentrate the fertilizer.

[0040] Reference Figure 1-2 Two support bars 7 are fixedly connected between the roller 3 and the lower side of the supply box 1, and one support bar 7 is assembled and connected to two rollers 3 located on the same side.

[0041] In this embodiment, the support bar 7 is used to make the lower side of the roller 3 lower than the guide tube 15, so that the guide tube 15 will not contact the ground when the supply box 1 moves.

[0042] Reference Figure 2 A bearing seat 8 is assembled and connected between the first transmission shaft 205 and the supply box 1, and the bearing seat 8 is fixedly assembled and connected to the upper side of the supply box 1.

[0043] In this embodiment, the bearing seat 8 is used to assemble the first transmission shaft 205 .

[0044] Reference Figure 1 : A sealing shell 9 is provided above the supply box 1 to cover the up and down reciprocating mechanism 2 and the rotating mechanism 6.

[0045] In this embodiment, the sealing shell 9 is used to prevent transmission components such as the bevel gear 601, the eccentric wheel 204, the second transmission shaft 602, the driving gear 603 and the driven gear 604 from being directly exposed to the outside.

[0046] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0047] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
