Description

Technical Field

[0001] The utility model relates to the technical field of corn crushing, and specifically refers to a crushing device of a corn crusher. Background Technique

[0002] A corn crusher is a mechanical device used to process corn kernels or other grains into powders or granules. It is usually driven by an electric or diesel engine and grinds corn kernels through rotating blades or grinding discs. This device is widely used in the agricultural and food processing industries to produce raw materials such as corn flour, corn meal, and corn starch, and can also be used for making feed or other industrial purposes.

[0003] At present, the toothed disc type corn crusher is widely used. Its advantages are small volume and fast discharging. However, when discharging, the throwing force of the material is too large, often making it difficult for the material receiving personnel to load the material well with bags, or causing large amounts of dust to be stirred up when falling into the container, affecting the operating environment. Moreover, when crushing corn for feed, corn straw is often used together with corn to prepare feed. At present, the corn crusher can crush corn, but the straw needs other equipment to complete the crushing, which is rather cumbersome. Content of the Utility Model

[0004] In order to solve the above various problems, the utility model proposes a crushing device of a corn crusher with small discharging force, convenient for material receiving, not easy to generate dust, and with the function of crushing straw attached, which is more convenient for the preparation of corn feed.

[0005] In order to solve the above technical problems, the technical solution proposed by the utility model is: a crushing device of a corn crusher, including a bracket and a crusher. The crusher is fixedly arranged on the bracket. The crusher is driven by a driving structure fixed on the bracket. One side of the crusher is provided with a first feeding port. An adjustable shutter is arranged at the first feeding port on the crusher. A crushing chamber is connected to the bracket. A crushing blade is rotatably arranged in the crushing chamber. The crushing blade is driven by a first motor fixed on the side wall of the crushing chamber. A second feeding port is arranged on the side wall of the crushing chamber. Discharge ports are arranged below both the crusher and the crushing chamber. Baffles are slidably arranged at both discharge ports. The same discharge chute is connected to both discharge ports. A reduction wheel is rotatably connected near the discharge port in the discharge chute. A number of reduction teeth are connected to the inner wall of the discharge chute.

[0006] Further, the bracket includes an upper bottom plate and a lower bottom plate. The four corners between the upper bottom plate and the lower bottom plate are connected by support rods. The crusher is fixedly arranged on the upper bottom plate.

[0007] Based on the above features, the cooperation of the upper bottom plate, the lower bottom plate and the support rods can not only stably support the device, but also provide sufficient operating space for corn crushing and material receiving.

[0008] Further, the driving structure includes a second motor fixedly arranged on the lower bottom plate. A first gear is connected to the output end of the second motor. The crushing knives in the crusher are driven by a rotating shaft rotatably connected to the side wall of the crusher. A second gear is connected to the extending end of the rotating shaft. The first gear and the second gear are driven by a toothed chain.

[0009] Based on the above features, the cooperation of the first gear, the second gear and the toothed chain enables the second motor to provide continuous and stable driving for the crushing knives in the crusher.

[0010] Further, a feed hopper is connected to the crusher at the first feed port.

[0011] Based on the above features, the feed hopper facilitates smooth feeding.

[0012] Further, a screw rod is connected to the crusher above the first feed port. A knob is threadedly connected to the screw rod. The adjustable shutter is slidably arranged between the knob and the side wall of the crusher. A through groove matching the screw rod is arranged on the adjustable shutter.

[0013] Based on the above features, the cooperation of the knob and the screw rod can loosen and fix the adjustable shutter, and the operation is simple and fast.

[0014] Further, the speed reducer includes a connecting shaft and speed reducing plates. The connecting shaft is rotatably connected in the discharge chute. A plurality of the speed reducing plates are uniformly fixed around the connecting shaft.

[0015] Based on the above features, the speed reducing plates can effectively block the crushed materials and reduce their falling speed. The arrangement of the connecting shaft enables the speed reducing plates to rotate after being impacted by the crushed materials, thereby realizing the smooth discharge of the crushed materials.

[0016] The advantages of the present utility model compared with the prior art are as follows: The arrangement of the discharge chute can guide the crushed corn and straw, making them fall out concentratedly, facilitating accurate material receiving. The arrangement of the speed reducer and speed reducing teeth inside can produce a certain blocking effect on the falling materials, thereby realizing effective force unloading, avoiding their splashing and generating dust, and being more convenient for collection. The arrangement of the crushing chamber and crushing knives can crush the straw, increasing the function of the device, facilitating the preparation of corn feed, and having stronger applicability.
