Technical Field

The utility model belongs to the field of machinery, and particularly relates to a crushing device for rice processing.

Background

The rice processing usually needs to be primarily crushed into broken rice before being ground into powder, and then the broken rice is ground so as to improve the grinding efficiency of the rice. However, the existing crushing device has the following defects:

1. the rice need control the feeding volume when broken, otherwise once the pan feeding too much can lead to the damage insufficient, also can lead to crushing roller department to consume power too big, leads to the motor to damage.

2. In some areas, the moisture content of the air is heavy, so that the rice is easy to absorb water and become damp to influence the crushing efficiency, and the low-temperature rice is hard and not easy to crush.

3. The crushing roller is easy to wear, the existing mode is to replace the whole crushing roller, the cost is high, and the replacement is complex.

fig. 2 is a schematic structural view of the active crushing roller.

Detailed Description

The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

Example 1

The crushing device for rice processing shown in fig. 1-2 comprises a crushing shell 1, a feed hopper 2, an active crushing roller 3, a passive crushing roller 4, a first driving wheel 5, an 8-shaped driving belt 6, an electric heater 7, a material fixing rotating shaft 8, a quantitative fan blade 9, a second driving wheel 10, a driving belt 11, a conical part 12, a supporting leg 13, a fixed rotating shaft 14, a bolt 15, an upper semicircular crushing roller shell 16 and a lower semicircular crushing roller shell 17

Wherein, the top of the crushing shell 1 is provided with a feed hopper 2, the bottom of the feed hopper 2 is provided with a quantitative feeding mechanism, and the periphery of the feed hopper 2 is provided with an electric heater 7; an active crushing roller 3 and a passive crushing roller 4 are installed in the crushing shell 1.

The crushing teeth on the crushing roller are convenient to replace when being damaged. The driving crushing roller 3 and the driven crushing roller 4 both comprise a fixed rotating shaft 14, and an upper semicircular crushing roller shell 16 and a lower semicircular crushing roller shell 17 are fixed on the fixed rotating shaft 14 through bolts 15. Thus, when the crushing roller needs to be replaced, only the bolt 15 needs to be loosened, and the upper semicircular crushing roller shell 16 and the lower semicircular crushing roller shell 17 need to be replaced, so that the whole crushing roller does not need to be replaced.

In order to save the power structure and enable the driving crushing roller 3 and the driven crushing roller 4 to rotate relatively, the driving crushing roller 3 is connected with a motor; and first driving wheels 5 are fixed on the driving crushing roller 3 and the driven crushing roller 4, and the first driving wheels 5 are in transmission connection through 8-shaped driving belts 6.

The quantitative feeding mechanism comprises a fixed material rotating shaft 8, and a plurality of quantitative fan blades 9 are fixed on the fixed material rotating shaft 8 along the circumferential direction; the fixed material rotating shaft 8 and the driving crushing roller 3 are both provided with second driving wheels 10, and a driving belt 11 is arranged between the second driving wheels 10. The crushing case 1 is formed at the bottom with a tapered portion 12. The bottom of the conical portion 12 is connected to legs 13.

When the rice crusher is used, rice is firstly placed in the feed hopper 2, water in the rice is evaporated by heating, and the rice is heated, so that the rice becomes crisp by increasing the temperature, and subsequent crushing is facilitated. Then the motor starts, and the motor drives through second drive wheel 10 after starting and decides material pivot 8 rotatory to make the rice between the ration flabellum 9 drop gradually. Wherein the speed that the rice dropped and the rotatory speed of crushing roller are fixed proportional relation promptly to keep the rice not to influence crushing effect owing to the too much blanking, also can not lead to crushing efficiency to reduce owing to the blanking is too little. In addition, the motor can work at a stable power, so that the service life of the motor is prolonged.

The above description is only one specific guiding embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modification of the present invention using this concept shall fall within the scope of the utility model.
