Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a small crushing and grinding machine with controllable feed rate. Background Technology

[0002] Various grains and cereals are mixed and ground into powder for consumption, resulting in a wider variety of healthy food products with different flavors. Currently, the market uses grinding equipment to grind grains into powder, which achieves this through the cooperation of moving and stationary grinding discs.

[0003] Currently, grinding mills are usually equipped with a hopper on top. Raw materials are poured directly into the hopper and flow into the grinding chamber by gravity. In this case, due to the mutual compression between the raw materials, blockage may occur at the discharge end, and the feed rate is not easy to control. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a small-scale crushing and grinding mill with controllable feed rate. This mill can control the feed rate by setting a liftable conical material seat. The rotating conical material seat loosens the raw material and prevents blockage.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A small-scale crushing and grinding mill with controllable feed rate includes a grinding chamber, a hopper installed on the top of the grinding chamber, a discharge pipe connected to the bottom of the hopper, a feed cylinder connected between the discharge pipe and the grinding chamber, and a liftable and rotatable conical material seat installed inside the feed cylinder. The circumferential inclined surface of the conical material seat cooperates with the opening of the discharge pipe to achieve control of the feed rate.

[0007] Preferably, the diameter of the feed cylinder is larger than the diameter of the discharge pipe.

[0008] Preferably, an electric push rod is fixedly installed inside the feed cylinder. The telescopic end of the electric push rod is connected to the bottom of the conical material seat through a rotating assembly. The electric push rod is used to drive the conical material seat to rise and fall to achieve opening and closing.

[0009] Preferably, the rotating assembly includes a motor, which is installed inside the telescopic end of the electric push rod, and the output end of the motor is fixedly connected to the bottom of the conical material seat.

[0010] Preferably, the conical material seat has multiple ribs radially arranged on its circumferential inclined surface, and the connection between the discharge pipe and the feed cylinder has a groove adapted to the ribs.

[0011] Preferably, a rotating shaft is fixedly connected at the top center of the conical material seat, passing through the discharge pipe and extending into the hopper. Multiple stirring rods are fixedly installed on the circumferential sidewalls of the rotating shaft inside the hopper and the discharge pipe.

[0012] Preferably, a limiting rod is fixedly installed on the bottom inner wall of the hopper, and the end of the limiting rod is provided with a limiting hole for the rotating shaft to pass through.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By installing an electric push rod and a conical material seat, the electric push rod drives the conical material seat to rise and fall. The circumferential inclined surface of the conical material seat cooperates with the opening of the discharge pipe to control the feed rate. The control is simple and effective.

[0015] 2. By installing a motor, rotating shaft, stirring rod, and ribs, during the feeding process, the motor is started to drive the conical material seat to rotate. Multiple ribs and stirring rods rotate synchronously with the rotating shaft. During the circumferential rotation of multiple ribs, the falling material is loosened to avoid blockage. Multiple stirring rods rotate at the bottom of the hopper and inside the discharge pipe to stir the material, preventing blockage and ensuring smooth feeding. Attached Figure Description
