Description
Technical Field
The invention relates to a Chinese chestnut sorting and grading machine, belonging to the field of fruit primary processing equipment.
Background
The Chinese chestnut is one of fruits which people like to eat, particularly, in mid-autumn seasons, every family can boil a large basin of Chinese chestnut to serve guests or eat the Chinese chestnut by oneself, and at ordinary times, a vendor special for frying Chinese chestnut to sell the Chinese chestnut also can eat the Chinese chestnut. Chinese chestnut has huge production and consumption amount every year. As is known to all, most of the ripe Chinese chestnuts naturally fall to the ground, and the shell with the thorn is removed after the Chinese chestnuts are picked up, so that the fruits with the hard shells can be obtained. The fruits with hard shells are mixed with a plurality of empty fruits, worm eaten fruits, rotten fruits and cracked fruits, and if the empty fruits, the worm eaten fruits, the rotten fruits and the cracked fruits are not removed, the eating of people can be influenced, and particularly, the rotten fruits contain aflatoxin which has great harm to human bodies. Empty shell fruits and worm-eaten fruits also affect the grade of the commodity.
At present, hollow fruits, worm eaten fruits, rotten fruits and cracked fruits in Chinese chestnuts are mainly sorted by hands, moldy parts of the surfaces of the moldy fruits are easy to remove by visual observation, but only the insides of the moldy fruits are moldy but cannot be identified for sorting, and the hollow fruits are difficult to remove by observation, so that a plurality of hollow fruits and the insides of the moldy or worm eaten fruits are always mixed in Chinese chestnuts sold in the market, the moldy fruits are eaten after the Chinese chestnuts are cooked, and people only need to vomit and rinse with clear water when eating the moldy fruits, and swallow can be carried out if the reaction is slow, so that potential health hazards are caused.
The classification of the Chinese chestnut is a necessary process of Chinese chestnut vendors, and the Chinese chestnut can be classified to have high quality and high price, so that the economic benefit is maximized.
For large-scale Chinese chestnut planting users, manual sorting is not feasible, a large amount of labor is needed, the sorting cost is increased, the sorting quality is difficult to improve, common consumers have endless family consumption, and only one Chinese chestnut planting user can be removed when eating. Therefore, it is necessary to develop an apparatus for easily removing inferior fruits such as empty fruits, mildewed fruits, etc. from chestnuts, but such an apparatus or technique has not been developed at present.
Disclosure of Invention
Therefore, the invention provides the Chinese chestnut sorting and grading machine which can quickly and efficiently remove empty fruits, rotten fruits, worm eaten fruits and cracked fruits in the Chinese chestnuts, automatically grade the Chinese chestnuts according to sizes, has a simple machine structure, is suitable for sorting and grading occasions of different scales, is beneficial to popularization and overcomes the defects of the prior art.
The Chinese chestnut sorting and grading machine is characterized in that the water tank and the cylindrical sieve are arranged on the frame and are communicated with each other through a chute, the water tank is internally provided with an inclined conveyor belt which is used for fishing out the Chinese chestnuts with sunk bottoms and conveying the Chinese chestnuts to the cylindrical sieve for grading, the floating Chinese chestnuts are fished out manually, and the conveyor belt and the cylindrical sieve are driven by a motor.
The conveying belt is installed on a head wheel and a tail wheel of the conveying belt to rotate, the head wheel end is high and installed on the water tank, the tail wheel end is low and installed at the bottom of the water tank, a belt pulley is installed on a head wheel shaft and is connected with a belt pulley on a motor shaft for transmission, a branch hanging plate is arranged on the surface of the conveying belt, and two side edges are provided with side blocking bands to prevent Chinese chestnuts from sliding downwards or falling sideways.
And the sub-hanging plate and the flange belt are provided with water leakage holes so that water on the belt can flow back to the water tank.
The large bevel gear is arranged on the barrel body of the cylindrical sieve and is in meshed transmission with the small bevel gear on the motor shaft, the sieve barrel is supported on the riding wheel to rotate, and the helical blades are arranged on the inner surface of the sieve barrel so as to push Chinese chestnuts entering the barrel from the inlet end to the outlet end.
The screen holes of the cylindrical screen are changed from small to large from the inlet end to the outlet end so as to classify the Chinese chestnuts from small to large, and the separation plate is arranged below the screen cylinder so as to prevent the separated Chinese chestnuts from being mixed together again.
The screen holes of the cylindrical screen are round holes, the aperture of the screen hole of the first half section is 20mm, the aperture of the screen hole of the second half section is 27mm,
the inlet end of the cylindrical sieve is provided with an annular baffle plate to prevent the Chinese chestnut from flowing back.
The motor for driving the conveying belt and the drum screen is the same motor, and a belt pulley and a small bevel gear are simultaneously installed on a motor shaft.
The water tank is provided with a feeding groove so that the Chinese chestnuts can be fed from the tail wheel end of the conveying belt.
The working principle of the invention is as follows:
the water tank is filled with clear water, the motor is started to drive the conveying belt and the cylindrical sieve, chestnuts to be sorted and classified are poured into the water tank through the feeding groove, because the density of empty chestnuts, worm-eaten chestnuts and mildewed chestnuts is lower than that of water and floats on the water surface, the chestnuts are picked up and sorted by a manual strainer and other tools, the normal chestnuts are higher than that of water and sink into the water, the chestnuts are conveyed out of the water tank by the conveying belt and fall into the chute, then the chestnuts automatically flow to the cylindrical sieve and are pushed forward by the spiral blades, the small-sized chestnuts fall from small holes in the front half section to form secondary chestnuts, the middle-sized chestnuts fall from large holes in the rear half section to form middle-sized chestnuts, and finally the remaining chestnuts are discharged from the tail end of the cylindrical sieve to form the first-class chestnuts. Thus, the automatic sorting and grading of the Chinese chestnuts are realized.
The invention has compact structure, less transmission parts and changeable size, is suitable for being made into large-scale equipment for processing Chinese chestnuts in a factory in a large scale, is also suitable for being made into small-scale machines for common people to use at home, and meets the requirement of temporary sorting.
Therefore, the invention can quickly and efficiently remove empty fruits, rotten fruits, moth-eaten fruits or cracked fruits in the Chinese chestnuts, automatically grade the empty fruits, the rotten fruits, the moth-eaten fruits or the cracked fruits according to the sizes, has simple and refined machine structure, is suitable for sorting and grading occasions of different scales, and is beneficial to popularization.
