Description

One-piece rice milling crushing self-separation combination machine

technical field

The utility model relates to a grain processing machine, in particular to a one-piece rice milling, pulverizing and self-separating combined machine.

Background technique

my country is a large agricultural country with nearly 900 million farmers. The work of accelerating agricultural mechanization in the vast agricultural areas of our country is of great significance to the construction of a new socialist countryside. At present, farmers in the vast rice-producing areas of our country have generally used rice mills for rice milling, which has a positive effect on reducing the labor load of farmers. According to the market survey: the one-piece rice milling, pulverizing and self-separating combination machine commonly used now has a better milling effect in the process of rice processing. function. However, in the actual processing process, there will often be defects in the use of rice and bran separation, which will reduce the rice yield and seriously affect the quality of finished rice. Its main reason is: the existing traditional rice milling machine is that a round sieve is installed outside the rice milling roller to carry out milling and rice bran separation and operate at the same time. After the bran material is leaked out by the round sieve, the rice grains are finally squeezed into the hopper by the rice milling roller to be discharged out of the machine. Undoubtedly, when the two processing operations of grinding and sorting are carried out in the circular sieve at the same time, the bran is separated by the natural leakage of the circular sieve. In fact, it is difficult for all the bran to leak out of the circular sieve for separation. If it is clean, there will always be a small part of bran mixed into the rice, which is one of the main reasons for the unclean separation of rice and bran. This is a technical defect in the rice bran separation link of the existing connected rice milling and self-separating combination machine.

Application number: 00259877.9 discloses a motor self-priming rice bran separator, which is fixedly supported on the fan cover shell of the motor to install a bran suction chamber, and the impeller installed on the extended shaft of the motor in the bran suction chamber forms a negative pressure airflow with the rotation of the motor , all the light bran material in the rice bran separation chamber is sucked into the rice bran separation chamber by the negative pressure bran suction pipe and discharged with the airflow to realize the effect of rice and bran separation, but the structure of the equipment is complicated.

Application number: 01263003.9 discloses a rice milling machine driven by a single-phase motor. It consists of a frame, a rice milling machine, a milling machine and a motor. On the frame, the rice milling machine and the pulverizer are installed above the motor, and the belt drive is used between the motor and the rice milling machine and between the motor and the pulverizer. The rice milling and crushing processes can be selectively carried out. The wind generated by the fan leads to the air inlet of the paddy separator on the rice mill to separate the rice and bran. The airflow generated by the cooling of the motor tail is introduced into the air chamber to blow out the bran. Although this processing machine can realize rice milling and winnowing rice bran operations, it disperses the cooling air volume of the motor, reduces the normal cooling performance of the motor, and affects the normal operation of the motor.

Utility model content

Aiming at the complex structure of the rice and bran separation device of the existing rice mill grinder, the separation device will affect the normal operation of the driving mechanism. The structure is simple, can guarantee the normal operation of the driving mechanism, and can save energy.

The one-piece rice milling, crushing and self-separating combination machine includes a rice milling device, a crushing device, and a separator. The rice milling device and the crushing device are respectively provided with a feed inlet, a working unit, and a discharge port. An air duct is arranged between the devices; the working unit of the rice milling device and the working unit of the crushing device share a rotating main shaft and are driven by a driving device.

One end of the air duct is connected to the shell of the crushing device and communicates with the crushing chamber of the crushing device; the other end communicates with the separator.

The utility model also has the following technical characteristics:

The separator is provided with a feed inlet, a rice outlet and a bran outlet.

A broken rice sorting sieve is arranged inside the separator, and a broken rice outlet is arranged at the bottom of the broken rice sorting sieve.

The air duct is a flexible air duct.

The rice milling device adopts a roller rice mill.

The roller rice mill is a horizontal rice mill.

The driving device is an electric motor or a diesel engine.

The working process of the present utility model is:

When the driving mechanism drives the main shaft to rotate, the main shaft drives the rice milling roller to grind and dehull the rice material to the separator through the discharge port of the rice milling machine, and the input rice material is in a falling state in the separation box. The rotor or fan blades of the crushing device rotate to generate air flow, and the air flow enters the separator through the air pipe to separate and process the falling rice materials, and complete the separation of rice and bran.

Compared with the prior art, the beneficial effects of the utility model are:

1. The utility model includes a rice milling device, a crushing device, and a separator. The rice milling device and the crushing device are respectively provided with a feed inlet, a working unit and a discharge port, and an air duct is arranged between the crushing device and the separator. One end is connected to the shell of the crushing device and communicates with the crushing chamber of the crushing device, and the other end communicates with the separator. In the process of rice milling, the separation of rice and bran is achieved by using the wind flow generated by the rotor or fan blades in the crushing device. The utility model has the advantages of simple structure, ingenious design, material saving and cost reduction, meanwhile, the cooling air volume of the driving mechanism will not be dispersed, and the normal operation of the driving mechanism can be guaranteed.

Two, the rice milling device of the present utility model and the working unit of the crushing device share a rotating main shaft. When milling rice, the rotor of the crushing device produces an inertial moment that acts on the rotating main shaft to reduce the workload of the motor; at the same time, when the grinder is working, the rotor of the rice mill is used to reduce the working load of the motor, thereby reducing electricity consumption, to achieve the purpose of saving energy.

3. The separator of the utility model is provided with a broken rice sorting sieve plate, and a broken rice outlet is arranged at the bottom of the broken rice sorting sieve plate. The rice that has been air-selected and separated from the bran material is processed by the broken rice sorting sieve. After the broken rice is naturally screened and separated by the broken rice sorting sieve, high-quality rice can be directly output from the rice outlet. The rice further improves the performance.
