Description

Material pushing device

Technical Field

The invention relates to a conveying machine, in particular to a material leveling device.

Background

When a belt conveyor or a spiral conveyor is used for feeding materials into a storage bin or a car hopper, the problems that the material falling point is single, the material distribution is uneven, and the utilization of the inner space of the storage bin or the car hopper is insufficient exist, a device for pushing the materials to be flat is needed, and similar devices or equipment are not found in the prior art.

Disclosure of Invention

The invention aims to disclose a device which can push materials in a stock bin or a car hopper flat in the charging process so as to fully utilize the space of the stock bin or the car hopper, and the adopted technical scheme is as follows:

the material leveling device comprises two groups of upright columns, wherein each group of upright columns spans over a storage bin or a car hopper, a horizontal guide rail is fixedly arranged at the upper end of each upright column, a roller of a crown block is in rolling fit with the horizontal guide rail, a fixed plate is fixedly arranged on a bottom plate of the crown block, a cylinder body and a sliding sleeve of an air cylinder or a hydraulic cylinder are fixedly arranged on the fixed plate, a sliding rod is in sliding fit with the sliding sleeve, the upper end of the sliding rod is fixedly connected with a cylinder rod of the hydraulic cylinder, the lower end of the sliding rod is fixedly connected with a rake tooth fixing frame, at least one rake tooth adjusting plate with the length direction orthogonal to the length direction of the horizontal guide rail is fixedly arranged on the rake tooth fixing frame, and a row. The cone-shaped materials piled in the material bin or the car hopper can be pushed flat through the forward and backward movement of the crown block, and the up and down stretching of the hydraulic cylinder can adapt to the gradual rising of the materials and the material leveling at different heights.

Furthermore, the fixed plate and the horizontal plane form an included angle of 45-90 degrees. The slide bar has a certain inclination, so that the bending strength of the slide bar is improved, and the slide bar is easier to propel materials and advance.

Furthermore, the cross section of the rake teeth is prismatic, and the lower ends of the rake teeth are tapered. The rake teeth not only can reduce the forward resistance, but also can push materials and crush the materials, so that the materials are more easily uniformly distributed and pushed, the design can realize forward and backward bidirectional acting, the efficiency is high, the power consumption is low, and the rake teeth are unique in distinguishing the traditional rake teeth.

Further, when the number of the rake teeth adjusting plates is two or more, the height of the rake teeth adjusting plate located at the front is lower than that of the rake teeth adjusting plate located at the rear, and the row of the rake teeth on the rake teeth adjusting plate located at the front is staggered with the row of the rake teeth on the rake teeth adjusting plate located at the rear. The design can realize small advancing resistance of the leveling material, uniform leveling material and no blind area leveling material in the storage bin.

Further, the overhead traveling crane is provided with at least two pairs of rollers, wherein one pair of rollers is driven to rotate by an electric motor or a hydraulic motor. This ensures synchronism of travel.

Furthermore, the device also comprises a wired or wireless control handle, and the control handle controls the stretching of the air cylinder or the hydraulic cylinder.

And the control handle controls the starting, stopping and steering of the motor or the hydraulic motor. The full automation and intelligent control can be realized, and the actions of advancing the loquat and the loquat teeth, protecting the rake teeth and positioning the carriage position can be improved.

Detailed Description

A material leveling device as shown in fig. 1-2, comprising two sets of 5 upright columns 5 crossing over a car hopper 7, wherein a horizontal guide rail 4 is fixedly arranged at the upper end of each set of upright columns 5, a roller 3 of a crown block 1 is in rolling fit with the horizontal guide rail 4, a fixing plate 13 is fixedly arranged on a bottom plate 2 of the crown block 1, and the fixing plate 13 and a horizontal plane form an included angle a of 80 degrees; the fixed plate 13 is fixedly provided with a cylinder body of the hydraulic cylinder 8 and a sliding sleeve 14, the sliding rod 9 is in sliding fit with the sliding sleeve 14, the upper end of the slide bar 9 is fixedly connected with the cylinder rod of the hydraulic cylinder 8, the lower end of the slide bar 9 is fixedly connected with a rake

tooth fixing frame

12, 2 rake tooth adjusting plates 10 with the length direction orthogonal to the length direction of the horizontal guide rail 4 are fixedly arranged on the rake tooth fixing frame 12, a row of rake teeth 11 are fixedly arranged on the rake tooth adjusting plate 10, the rake tooth adjusting plate positioned in the front in the direction of the vehicle head is lower than the rake tooth adjusting plate positioned in the rear, and the row of rake teeth 11 on the front rake adjusting plate is staggered with the row of rake teeth 11 on the rear rake adjusting plate, the number of the row of rake teeth 11 on the front rake adjusting plate is 10, and the number of the row of rake teeth 11 on the rear rake adjusting plate is 11. The cross section of each rake tooth 11 is prismatic, and the lower end of each rake tooth is tapered. The width and thickness of the rake teeth close to the center are larger, and the width and thickness of the rake teeth closer to the outer side are smaller, so that the tapered material accumulation which is to be pushed flat is adapted.

The crown block 1 has two pairs of the rollers 3, wherein the front pair of the rollers 3 is rotated by an electric motor or a hydraulic motor. The hydraulic control device also comprises a wired or wireless control handle, wherein the control handle controls the hydraulic cylinder 8 to stretch and control the motor or the hydraulic motor to start, stop and turn.

When materials are loaded into the hopper 7 through a belt conveyor or a spiral conveyor, the materials cannot uniformly flow to all parts of the hopper due to friction among the materials and can be accumulated in the hopper in a conical shape, when the conical top of the materials exceeds the upper edge of the hopper and the conical bottom is below the upper edge of the hopper, the hydraulic cylinder 8 can be controlled at the moment, so that the rake tooth fixing frame 12 descends to a proper position above the materials, the crown block 1 is started to move forwards and backwards to drive the rake teeth 11 to move forwards and backwards to uniformly and flatly distribute the materials to all parts of the hopper, then the crown block 12 is lifted to continuously load the materials, the rake tooth fixing frame 12 can be descended again, the crown block 1 is started to move forwards and backwards again until the materials are uniformly and flatly distributed to be not more than the upper edge of the hopper, labor power is saved, and the efficiency and the utilization rate of the hopper are greatly improved.
