Description

Technical Field

[0001] The utility model specifically relates to a sand feeding device. Background Art

[0002] In the process of transporting construction materials, the loading process of the cargo box of the shipping vehicle is based on the position of the loading platform. Considering the prior art of sand discharge and loading, since the discharge port is mostly fixed, when the sand falls into the cargo box, it will form a cone-shaped accumulation at one point in the cargo box. For this phenomenon, it is usually necessary to suspend the sand discharge and loading, and then have the construction workers enter the cargo box to smooth the accumulated sand before discharging the sand and loading. However, this sand discharge and loading method not only reduces the efficiency of sand discharge and loading, but also increases the labor intensity of the construction workers. Therefore, in view of the above technical problems, a sand feeding device is proposed. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a sand distributing and feeding device to improve the sand distributing and feeding efficiency and reduce the labor intensity of construction workers.

[0007] The longitudinal material distributing mechanism comprises a second discharge pipe, a second corrugated pipe and a transmission assembly. The second discharge pipe is arranged on the first discharge pipe so as to be able to swing longitudinally and is located below the first discharge pipe. The second discharge pipe and the first discharge pipe are connected through the second corrugated pipe. The transmission assembly connects the first discharge pipe and the second discharge pipe to convert the reciprocating sliding of the first discharge pipe into the reciprocating swinging of the second discharge pipe.

[0008] The beneficial effects of the above-mentioned sand feeding device are:

[0009] When discharging sand and loading, sand falls into the bucket through the first corrugated pipe, the first discharge pipe, the second corrugated pipe and the second discharge pipe.

[0030] In the above embodiment, the screw 203 is driven to rotate by the motor 204, and the rotation of the screw 203 cooperates with the thread of the limit block 2021 to drive the limit block 2021 to drive the first discharge pipe 202 to slide. The screw 203 is driven to rotate in the opposite direction by the motor 204, and the reverse rotation of the screw 203 cooperates with the thread of the limit block 2021 to drive the limit block 2021 to drive the first discharge pipe 202 to slide in the opposite direction, and it is convenient to drive the first discharge pipe 202 to slide back and forth horizontally. When the discharge port of the sand storage bin is opened to allow sand to be discharged from the first discharge pipe 202 into the truck bed through the first corrugated pipe 201, the first discharge pipe 202 can spread sand in the truck bed horizontally.

[0031] See also Figures 1 to 3In one embodiment, the longitudinal fabric mechanism 30 includes a second discharge pipe 301, a second corrugated pipe 302 and a transmission assembly. The second discharge pipe 301 is longitudinally swingable and is arranged on the first discharge pipe 202 and is located below the first discharge pipe 202. The second discharge pipe 301 and the first discharge pipe 202 are connected through the second corrugated pipe 302. The transmission assembly connects the first discharge pipe 202 and the second discharge pipe 301 to convert the reciprocating sliding of the first discharge pipe 202 into the reciprocating swing of the second discharge pipe 301.

[0032] Specifically, two groups of connecting rods 303 are arranged on the circumference of the second discharge pipe 301, and one end of the two groups of connecting rods 303 is hinged on the first discharge pipe 202 through a rotating shaft so as to be able to swing longitudinally.

[0036] The specific implementation of the above-mentioned sand feeding device is as follows:

[0037] By opening the discharge port of the sand storage bin, the sand passes through the first bellows 201, the first discharge pipe 202, the second bellows 302 and the second discharge pipe 301 and falls into the bucket. At the same time, the motor 204 is started to drive the screw 203 to rotate. The rotation of the screw 203 and the threaded cooperation of the limit block 2021 can drive the limit block 2021 to drive the first discharge pipe 202 to slide, and the motor 204 drives the screw 203 to rotate in the opposite direction. The reverse rotation of the screw 203 and the threaded cooperation of the limit block 2021 can drive the limit block 2021 to drive the first discharge pipe 202 to slide in the opposite direction, and the first discharge pipe 202 is driven to slide horizontally and reciprocally. When the first discharge pipe 202 slides reciprocatingly in the horizontal direction, the first discharge pipe 202 drives the second discharge pipe 301 to move reciprocatingly in the horizontal direction through the two sets of connecting rods 303, and at the same time drives the sliding seat 305 to move reciprocatingly in the horizontal direction. The reciprocating movement of the sliding seat 305 drives the lever 3052 to move reciprocatingly in the horizontal direction. The lever 3052 can reciprocate horizontally and cooperate with the guide slot 3061 to drive the sliding seat 305 to reciprocate longitudinally. The sliding seat 305 can drive the rack 3051 to reciprocate longitudinally by the reciprocating longitudinal movement of the rack 3051 and the gear 304 to drive the connecting rod 303 to swing longitudinally. The longitudinal reciprocating swing of the connecting rod 303 can drive the second discharge pipe 301 to swing longitudinally. It is convenient to drive the second discharge pipe 301 to reciprocate horizontally and longitudinally. When sand is discharged from the first discharge pipe 202 through the second corrugated pipe 302 from the second discharge pipe 301 into the bucket, the second discharge pipe 301 can reciprocate horizontally and reciprocate longitudinally to spread sand in the bucket. By spreading sand in the bucket horizontally and longitudinally, sand accumulation in the bucket during sand discharge and loading can be avoided, thereby eliminating the need for subsequent shutdown and smoothing operations, thereby improving the efficiency of sand discharge and loading and reducing the labor intensity of construction personnel.
