Description

The automatic adjustable rice mill

Technical field:

The utility model relates to rice mill, belongs to the technical field of small-scale agricultural machinery, particularly a kind of automatic adjustable rice mill that is used for the husk rice operation for peasant family.

Background technology:

Current, China governments at all levels pay much attention to and solve conscientiously the agriculture, rural areas and farmers problem, effectively advanced the high speed development of China's agricultural machinery cause, generally promoted the use of miniature rice mill at the peasant family in vast paddy rice producing region and carried out the husk rice production operation, this all has crucial meaning to work burden and the ripe rice of the raising end product quality that alleviates vast farmers.The rice mill that generally uses mainly comprises by feed hopper now, the charging adjusting device that the charging adjustable plate constitutes, by the roller that is installed in the body, the husk rice cutter, the stone roller system device that bolter constitutes, by rice output outlet, several parts such as discharging adjusting device that the discharging adjustable plate constitutes and actuating unit are formed, its operation principle is that paddy is ground in the whitening chamber of system device by the input of charging adjusting device, drive the roller rotation by actuating unit, the rotation roller in whitening chamber to paddy grind the system and at the husk rice cutter, form to push under the interact together of bolter and discharging adjustable plate and roll frictional force, gradually paddy is peeled off shelling, after chaff is removed in the bolter sorting, can export ripe rice finished product continuously again by rice output outlet.Obviously the size that rolls frictional force of pushing that forms in the quality of the ripe rice finished product of the system of grinding and the whitening chamber is closely related; mainly grinds that factors such as flow that system paddy expects determine and push the size that rolls frictional force by the installation site of husk rice cutter and institute; roll frictional force when too big when pushing; can produce too much cracking rice; influence rice milling yield; as push and roll frictional force when too small; thoroughly can in ripe rice finished product, not carry grain secretly because of the system of grinding again; have a strong impact on the product quality of ripe rice; though; distance between adjustment husk rice cutter and the rice milling roller can be regulated the size that rolls frictional force of pushing in the whitening chamber; but; it can only be opened cover and just can carry out under stopped status; and under the state of the normal running continuously of rice mill; wanting automatically in the following feedback stochastic and dynamic ground regulation and control whitening chamber institute to grind the flow that system paddy is expected, roll frictional force and be in best husk rice state all the time thereby accurately control to push in the whitening chamber, then is the key point of raising rice mill product quality.

The utility model content:

The utility model is a kind of follow-on automatic adjustable rice mill of making at traditional rice mill, it can be from the running status of motion tracking rice mill, according to pushing the situation of change that rolls frictional force in the whitening chamber, automatically accurately control the flow of paddy material, make to push in the whitening chamber and roll frictional force and maintain optimum state all the time, it is simple and direct to the utlity model has structure, manufacture easily, easy for operation, the noise that operates steadily is little, reduce the amount of cracking rice, improve the remarkable advantage of rice milling yield and ripe rice end product quality, its goal of the invention is achieved in that it is mainly by the bearing box that is connected in the body two ends, the main shaft of roller is installed, the feed hopper seat, following sieve and top sieve constitute, it is characterized in that: device is done the slide seat body of dowel hole on the main shaft of discharge port end, be fitted with baffle plate on the slide seat body, the interior bearing pin of dowel hole that is solidly plugged in slide seat body is connected with the pull bar of being furnished with regulating spring, inserting solid slide seat body by bearing pin does not rotate with main shaft, can farthest reduce noise in the course of the work, when going out meter, the sliding baffle plate that is assigned in slide seat body can rotate with the rice material, can further reduce mechanical load and noise, and baffle plate can dynamically be responded to and pushes the situation of change that rolls frictional force in the whitening chamber, under the acting in conjunction of regulating spring, axially pass slide seat body along main shaft, the size of auto-control discharging opening, can realize accurately controlling the flow of paddy material in the whitening chamber, keep to push in the whitening chamber and roll the purpose that frictional force is in optimum Working all the time.

The utility model also has following technical characterictic:

The pull bar cunning is through in the through hole of screw press, can sets the precompression of regulating spring easily, manipulate very convenient by the nut that is fitted to screw press.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment:

The utility model is implemented by following technical scheme: it is mainly by the bearing box 12 that is connected and installed in body 17 two ends, 22, the main shaft 1 of roller 2 and belt pulley 23 is installed, feed hopper seat 21, under sieve 3 and top sieve 18 constitute, bottom device at feed hopper seat 21 has material-feeding plugboard 20, can regulate the inlet amount of paddy easily, device is done the slide seat body 13 of dowel hole 11 on the main shaft 1 of discharging opening 15 ends, on slide seat body 13, be fitted with baffle plate 14 by collar 16, the dowel hole 11 interior bearing pins 5 that are solidly plugged in slide seat body 13 are connected with the pull bar 10 of being furnished with regulating spring 6, pull bar 10 sliding being through in the through hole of screw press 9, rotation is fitted to the precompression that nut 8 on the screw press 9 can be set regulating spring 6 easily, it is work like this: paddy is by in the feed hopper seat 21 input whitening chambers 19, by 1 rotation of motor drives main shaft the paddy system of grinding is peeled off shelling, the chaff material is discharged by chaff discharging port 4 after sieve 3 and top sieve 18 sortings are sieved down, the ripe rice finished product of the system of grinding is pushed baffle plate 14, when the sliding baffle plate 14 that is assigned in slide seat body 13 rotates with the rice material, can dynamically feed back and push the variation that rolls frictional force in the whitening chamber 19, under the acting in conjunction of regulating spring 6, promote slide seat body 13 along main shaft 1 axial slip, automatically control discharging opening 15 opening degrees, the regulation and control rice output, by going out the ripe rice of rice bucket 7 outputs finished product, realize accurately control paddy materials flow amount, keep pushing in the whitening chamber 19 and roll frictional force and be in optimum state all the time, improve the purpose of rice mill product quality.
