[0002] Compound fertilizers are widely used in agriculture and forestry, and harmless composting has become an important product under the demand for environmental protection. The demand for fermenting food waste to produce fertilizer is increasing, but conventional food waste composting fermentation equipment is complex and costly.

[0003] According to the search, the Chinese patent document announcement number: CN113943178A discloses a fertilizer production device. This solution divides the barrel body into two sealed spaces by arranging a partition device, and domestic garbage is thrown into the barrel body. The opening of the partition device is closed, and the barrel cover is closed. The crushing device in the center of the barrel cover crushes the domestic garbage. After the crushing is completed, the opening is opened, and the crushed garbage enters the fermentation device. The heating mechanism in the fermentation device heats to increase the fermentation speed in the fermentation device. The stirring mechanism works to stir the crushed domestic garbage evenly to increase the fermentation efficiency. The temperature in the fermentation device is controlled by a temperature sensor arranged on the inner wall of the barrel body. The fertilizer production device of the present invention is used to produce fertilizer after fermenting domestic garbage, which is environmentally friendly and intelligent.

[0004] However, during the fertilizer production process, the management of the filler when the fertilizer is stirred is extremely complicated. Most of the materials are added by manual control.

[0028] Embodiment 1:

[0029] See also Figure 1-4 As shown, an embodiment of the utility model is a feeding device for producing a drum compound fertilizer, comprising a cylinder 1, a supporting leg 2 is fixedly provided at the lower end of the cylinder 1, a feeding port 4 is installed on the upper end surface of the cylinder 1, and a hopper 5 is installed at the top of the feeding port 4.

[0030] A support platform 9 is installed in the inner cavity of the feeding port 4, a material distribution plate 25 is installed on the top of the support platform 9, a support chamber 6 is installed on the left outer wall of the feeding port 4, and an electric hydraulic push rod 7 is installed in the inner cavity of the support chamber 6.

[0031] The output end of the electric hydraulic push rod 7 is fixedly provided with a sealing plate 8, the upper end surface of the cylinder 1 is provided with a water inlet 14, and the top of the water inlet 14 is provided with a water pump 13. The length of the support chamber 6 is twice the length of the sealing plate 8, which can realize the switch of the sealing plate 8. When the liquid level in the cylinder 1 drops to the water level switch 17, the water level switch 17 controls the water pump 13 to start pumping the mother liquid, thereby realizing the effect of automatically replenishing the mother liquid.

[0032] A pressure switch 15 is installed on the water inlet 14, a control device 20 is installed on the left outer wall of the cylinder 1, and a discharge port 18 is installed at the bottom of the right outer wall of the cylinder 1. When the water pump 13 pumps mother liquid, the pressure switch 15 on the water inlet 14 is affected by the water pressure to control the closing of the solenoid valve 19.

[0033] The discharge port 18 is provided with a solenoid valve 19, and the inner cavity of the cylinder 1 is provided with a water level switch 16 and a water level switch 2 17 from top to bottom, and the material distribution plate 25 includes a motor 10.

[0035] The top of the motor 10 is equipped with a rotating rod 11, and the top of the rotating rod 11 is equipped with a conical disk 12. The control device 20 is electrically connected to the electric hydraulic push rod 7, the motor 10 and the electromagnetic valve 19 respectively. The pressure switch 15 is electrically connected to the electromagnetic valve 19. The water pump 13 is electrically connected to the water level switch 16 and the water level switch 2 17 respectively.

The feeding port 4 is provided with a fixed movable groove matching the sealing plate 8, so that the sealing plate 8 can seal the feeding port 4 and control the feeding of solid fertilizers. The position of the water level switch 2 17 is higher than the top position of the discharge port 18, so that the cylinder 1 is completely unloaded during the period from when the water pump 13 starts to pump water to when the pressure switch 15 controls the electromagnetic valve 19 to close.

The starting motor 22 can drive the rotating shaft 23 to rotate, and the rotation of the rotating shaft 23 can drive the stirring blade 24 to rotate. The structural setting of the stirring blade 24 can improve the mixing degree of the fertilizer, thereby improving the production quality of the device.

At this time, the electric hydraulic push rod 7 drives the sealing plate 8 to open, and the solid fertilizer feeding operation is carried out. When feeding, the large pieces of fertilizer particles are broken up by the use of the dividing plate 25, and the contact area when the fertilizer is dissolved is increased, thereby facilitating stirring, shortening the stirring time, and improving work efficiency. The feeding speed is adjusted by adjusting the size of the feeding port 4, and the quantity ratio of the solid material and the liquid material is adjusted. When the liquid level reaches the water level switch 16, the water level switch 16 controls the water pump 13 to close and start stirring.
