Description

An automatic feeding, grading, blowing and hoisting machine

【Technical field】

The invention relates to the technical field of agricultural machinery, in particular to the technical field of an automatic feeding, grading, blowing and hoisting machine.

【Background technique】

The sieve can filter out the impurities whose volume is different from that of the material through the volume, but it cannot remove the impurities that are similar to the volume of the material. It is necessary to use the hoisting machine to clean the material twice. The hoisting machine is a simple cleaning method for grain. Miscellaneous equipment can remove light impurities and large impurities in grain to facilitate grain storage. Various types of grain cleaning machines use different working principles to separate grain particles from impurities. Commonly used are the following 6 kinds. Separation according to particle size uses a woven wire screen or a punched metal plate as the screen surface. It can be divided into flat screen surface with reciprocating vibration or plane rotation and cylindrical screen surface with rotation around the axis. According to the size of the sieve hole on the sieve relative to the size of the grain particles, there are the following two types of equipment: ① The sieve hole is slightly larger than the maximum diameter of the grain particles. Such as large miscellaneous sieve and cylinder sieve. Its function is to make the grain and smaller impurities pass through the sieve holes, and the larger impurities are discharged as the oversize. The large miscellaneous sieve is to feed the grain to the upper belt of the ring-shaped working mesh belt. During the movement, the small impurities pass through the sieve and fall to the lower belt. The larger impurities such as paper pieces, sack pieces, rope ends, Masonry, mud, wood and long straw are removed as the sieve, and some small impurities such as dust and sand are removed through the sieve holes when the grain continues to flow through the fixed inclined sieve surface at the outlet. The grain is discharged out of the machine after being treated by strong suction. The main part of the cylindrical screen is a horizontal cylinder composed of punched sieve plates, a brush for cleaning the screen holes, and a suction and dust removal device. Grain enters the cylinder and is discharged through the large sieve holes, while large impurities accumulate on the sieve surface and are discharged from one end of the cylinder. These two types of equipment are used for preliminary cleaning when grain enters the warehouse. ② The sieve hole is smaller than the diameter of the smallest grain particles, such as reciprocating vibrating screens, flat rotary screens and high-speed vibrating screens. Impurities with small grain particles can be removed through the sieve holes, and the grain is discharged as the oversize. They are all used in the cleaning process after the grain is out of the warehouse and before processing. The cleaned grain is discharged as the oversize of the bottom sieve. If the sieve surface with larger sieve holes is replaced, it can also be used for preliminary cleaning. The reciprocating vibrating screen is driven by an eccentric shaft or a self-balancing vibrator, and is generally equipped with 3 layers of screen surfaces. Large impurities are discharged on the upper short sieve; large heterogeneous grains are discharged on the second sieve; small impurities are discharged through the sieve holes of the third sieve. The grain entering and exiting the machine are all processed by suction to remove light impurities. The screen body of the plane rotary screen is suspended by 4 sets of suspenders, driven by the balance wheel for plane rotary motion, and has 2 layers of screen surfaces. After changing its structure and working parameters, it can also be used for grading broken rice. The screen body of the high-speed vibrating screen moves circularly with small amplitude in the vertical plane under the action of the centrifugal inertial force generated by the high-speed rotation of the balance weights on both sides, and has 2 to 4 layers of screen surfaces. It is used to separate barnyard from rice, and the effect is better. Separation by specific gravity is used to separate impurities that are similar in size and shape to grain particles but different in weight, such as stones, mud, metal particles, glass, ceramics, and cinders. There are two kinds of separation methods: wet method and dry method: ① The typical equipment of wet method is a wheat washing and drying machine, which is composed of a spiral washing tank and a vertical drying part. The specific heavy impurities settle quickly in the washing tank, accumulate at the bottom of the tank and are sent to the discharge outlet by the small screw conveyor; the wheat grains are floated to the drying part by the big screw conveyor to remove the free water on the surface. ②Dry equipment includes specific gravity destoner and specific gravity grading table. Grain is evenly fed to an inclined and reciprocating vibrating porous plate (scale orifice plate or steel wire woven mesh plate) in the specific gravity destoner, and is fluidized by a controllable airflow, and becomes a semi-suspended state. Self-gravity flow to the lower end discharge. Heavy stones, mud, etc. are moved against the upper end of the perforated plate due to reciprocating vibration, and are discharged through the stone accumulation area. There are two types of suction and blowing methods to provide airflow. The working principle and structure of the specific gravity grading table is similar to that of the specific gravity de-stoner: first divide the grain and impurities into two parts according to the weight, and then clean them separately, which can reduce the number of subsequent cleaning equipment or use smaller equipment. Dry equipment can save water, prevent waste water from polluting the environment, and is easy to maintain. It has gradually replaced wet equipment. The impurities or materials separated by shape separation are similar in size to grain particles, but different in shape, such as buckwheat, pea, barnyard barnyardgrass, oats and barley. Its typical equipment includes: ①Screw separator. There are no moving parts, no power equipment is required, and a large outer helicoid surrounds several small inner helicoids on its vertical shaft. Grain is fed into the entrance of the inner helicoid from the top, and the spherical seed impurities in it can be thrown to the outer helicoid under the action of centrifugal force due to fast rolling and large momentum, and then discharged from the outlet. Grain particles then flow to each outlet along each inner helicoid. This kind of equipment has low productivity and can only be used as an auxiliary machine. ②Drum selection machine. Its working part is a slightly inclined horizontal rotating drum with many pockets (bag holes) on the inner surface and a spiral collecting tank with adjustable position in the middle. Any particles (spherical and short) that can stay in the socket are lifted with the rotation of the drum, and fall into the spiral collection tank and then discharged out of the machine, and the grain is discharged from the outlet end of the drum. ③Pocket plate selection machine. Its working parts are a group or several groups of cast iron discs installed coaxially, with dense sockets on both sides. When the disc rotates, the lower half of the disc is buried with grain, and the short grains (buckwheat, barnyard millet and broken rice, etc.) that enter the socket are brought to a certain height, and then fall into the collecting tank on the side of the machine and flow out. The structure of the traditional hoisting machine is relatively complicated, the ability to remove impurities is not ideal, and it is troublesome to clean up materials and impurities. The market needs a hoisting machine that can separate impurities and materials through multi-layer tuyere, with good separation effect and good separation of materials. The collection is convenient, and the equipment structure is simple, the application is convenient, and it can meet the needs of different materials for impurity removal.
