Description

TECHNICAL FIELD

[0001] The utility model relates to a grain depot feed inlet telescopic chute. BACKGROUND

[0002] In the agricultural field, grains are mostly stored in grain depots, which can ensure that the grains are stored in a dry and safe environment for a long time, avoiding the influence of adverse factors such as dampness, insect damage, rat damage, and mold.

[0003] In related technology, vehicles transporting grains use on-board grain suction machines to suck the grains in the vehicle compartment, and a pipeline is erected between the grain suction machine and the grain depot to suck the grains in the vehicle compartment into the grain depot. This method does not require manual operation and greatly improves the efficiency of grain feeding.

[0004] Most of the pipelines installed on the existing grain depot feed inlet are single telescopic pipelines, which can control the discharge amount by adjusting the length of the telescopic pipeline. However, because the pipeline has telescopic properties, dust will be scattered when the feed inlet discharges, polluting the environment. To solve the above problems, a grain depot feed inlet telescopic chute is proposed to solve the above problems. SUMMARY

[0005] Therefore, the utility model provides a grain depot feed inlet telescopic chute, dust will be blown into the air through the feed inlet, dust will enter the dust chamber through the air vent, and the dust will be protected by the telescopic cloth tube for the first time, and the dust will be protected by the dust bag on the dust sleeve for the second time, thereby protecting the atmospheric environment.

[0006] To solve the above technical problems, the utility model provides a grain depot feed inlet telescopic chute, which comprises a telescopic base connected to the feed end of the telescopic pipe, a discharge base connected to the discharge end of the telescopic pipe, an upper positioning ring provided on the top of the telescopic base, a lower positioning ring provided on the upper part of the outer wall of the discharge base, a telescopic device provided between the upper positioning ring and the lower positioning ring, a telescopic cloth tube provided on the outer surface of the telescopic pipe, a dust sleeve provided on the outer surface of the telescopic cloth tube, a dust chamber provided between the telescopic base and the discharge base, and an air permeable component provided between the discharge base and the discharge end of the telescopic pipe.

The filter ring is arranged in the inner ring of the first positioning ring and is used to connect and fix the discharging end of the telescopic pipe and the discharging base. A plurality of air permeable openings are vertically arranged on the surface of the filter ring and are used to allow the dust floating from the grain inlet of the grain bin to enter the dust chamber. The air permeable openings are in communication with the dust chamber. The side of the first positioning ring close to the dust chamber is provided with a sealing ring, which is used to reinforce the connection gap between the first positioning ring and the discharging base.

[0008] The telescopic device comprises a plurality of positioning blocks mounted on the lower surface of the upper positioning ring, which are used to connect the upper positioning ring and the driving end of the electric telescopic rod. The lower end of each positioning block is provided with an electric telescopic rod, which is used to drive the connecting block to move up and down, so as to lift the lower positioning ring fixed to the connecting block, thereby lifting the discharging base fixed to the lower positioning ring. The telescopic end of each electric telescopic rod is provided with a connecting block, which is used to connect the telescopic end of the electric telescopic rod and the lower positioning ring. The connecting block is connected to the upper surface of the lower positioning ring.

[0010] The dustproof sleeve comprises a dustproof bag arranged axially along the telescopic cloth tube. The dustproof bag is in the shape of a cylinder formed by the dustproof bag and is connected by knitting at the joint. The dustproof bag is hollow and is used to prevent dust from penetrating the telescopic cloth tube and floating into the air, thereby protecting the atmospheric environment. The top of the dustproof bag is detachably provided with an upper ring groove, which is used to connect the top of the dustproof bag and the telescopic base. The bottom of the dustproof sleeve is detachably provided with a lower ring groove, which is used to connect the bottom of the dustproof bag and the discharging base.

[0011] The upper positioning ring is provided at the top with a discharging pipe in communication. The discharging pipe is used to allow the grain sucked by the grain suction machine to enter the telescopic pipe. The upper part of the discharging pipe is provided with a first flange, which is used to connect with the discharging pipeline of the grain suction machine.

[0015] 2. The material is connected to the grain suction machine through the first flange and the discharge pipe. The electric telescopic rod is started to adjust the distance between the lower positioning ring and the upper positioning ring, thereby adjusting the distance between the telescopic base and the discharge base. This allows the telescopic pipe to extend and retract, thus controlling the amount of material discharged into the feed inlet.

[0016] 3. The feed nozzle is used to allow grain to smoothly enter the feed inlet of the grain silo, thereby reducing the probability of grain blockage. Attached Figure Description
