Description

Technical Field

[0001] The utility model relates to the technical field of high-chromium balls, in particular to a high-chromium ball storage and transfer device. Background Art

[0002] As grinding media in ball mills, high chromium balls are widely used in mining, metallurgy, cement production and other industries. High chromium balls need to be replaced regularly after long-term use, which requires a storage and transfer device to deliver new balls into the ball mill. In the prior art, a hopper is usually used to store and transfer high chromium balls. Since the hopper is only a frame-type storage bin, the high chromium balls will accumulate in the storage bin, which will lead to squeezing. In addition, as the hopper is transported and bumped, the high chromium balls will be squeezed, collided and rubbed in the frame-type storage bin, thereby damaging the surface of the high chromium balls.

[0003] Therefore, in order to solve the defect that high chromium balls are easily damaged on the surface during storage and transfer, it is necessary to propose a high chromium ball storage and transfer device. Utility Model Content

[0004] The purpose of the utility model is to provide a high-chromium ball storage and transfer device, which can place high-chromium balls in rows through storage tubes to prevent adjacent high-chromium balls from colliding with each other. At the same time, a fixed plate can be used to press the high-chromium balls against the inner wall of a storage tank to prevent the high-chromium balls from shaking left and right in the storage tank, thereby reducing the friction between the high-chromium balls and the inner wall of the storage tank, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A high chromium ball storage and transfer device comprises a cart and a storage box fixed to the upper surface of the cart, wherein a plurality of storage tubes are installed in a rectangular array in the storage box, a feeding port is welded at the bottom end of the storage tube, a storage trough is opened in the storage tube, and a plurality of balls are placed in a row in the storage trough;

[0007] A fixing plate is movably provided in the material storage trough, a telescopic rod is fixedly connected to the back end of the fixing plate, and a spring is provided on the outer sleeve of the telescopic rod.

[0008] Preferably, the bottom of the cart forms a collection frame, and universal wheels are installed on the lower surface of the collection frame.

[0009] Preferably, the bottom of the discharge port passes through the surface of the cart and extends to the upper end of the collection frame.

[0010] Preferably, a push handle is welded symmetrically on the upper surface of the cart.

[0011] Preferably, a movable groove is provided at the side end of the material storage trough, and a telescopic rod is fixed in the movable groove.

[0012] Preferably, one end of the spring is fixedly connected to the movable groove, and the other end of the spring is fixedly connected to the fixed plate.

[0013] Preferably, a finger groove is provided at the upper end of the fixing plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. This high chromium ball storage and transfer device can arrange the balls in a single layer through the storage tube, avoiding mutual collision between the balls, thereby reducing the risk of damage to the ball surface. At the same time, the storage in the tube can ensure that the balls are arranged in a certain order, reduce the blockage of the discharge port, and improve the patency of the discharge;

[0016] 2. The high chromium ball storage and transfer device can press the ball tightly against the inner wall of the storage tank through the fixing plate, thereby fixing and limiting the ball, preventing the ball from shaking left and right in the storage tank, reducing the friction between the ball and the inner wall of the storage tank, and thus reducing the damage to the surface of the ball.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] For technical questions on how to reduce collisions between spheres, see Figure 1-Figure 2 , this embodiment provides the following technical solutions:

[0024] A high chromium ball storage and transfer device comprises a trolley 1 and a storage box 2 fixed on the upper surface of the trolley 1, the bottom of the trolley 1 forms a collection frame 11, the lower surface of the collection frame 11 is equipped with universal wheels 12, and the upper surface of the trolley 1 is symmetrically welded with a push handle 13.

[0025] A plurality of storage tubes 21 are installed in a rectangular array in the storage box 2, a discharge port 22 is welded at the bottom end of the storage tube 21, the bottom of the discharge port 22 passes through the surface of the cart 1 and extends to the upper end of the collection frame 11, a storage trough 23 is opened in the storage tube 21, and a plurality of spheres 3 are placed in a row in the storage trough 23.

[0026] Among them, an end cover is threadedly connected at the discharge port 22, and the collection frame 11 is provided to facilitate the collection of high-chromium balls. When the high-chromium balls in the storage box 2 need to be taken out, the end cover at the discharge port 22 is opened, so that the high-chromium balls in the storage tube 21 are discharged from the discharge port 22 by gravity and fall into the collection frame 11, which is convenient for the operator to take.

[0027] Specifically, the spheres 3 are placed in the storage trough 23 of the storage tube 21 in sequence, so that the spheres 3 can be stored in a row, reducing the mutual collision between adjacent spheres 3. At the same time, when the spheres 3 need to be transported, the universal wheels 12 can be pushed by the push handle 13 to move the cart 1 to realize the transportation of the spheres 3.

[0028] To solve the technical problem of how the device can reduce the friction between the ball and the inner wall, please refer to Figure 3-Figure 4 , this embodiment provides the following technical solutions:

[0029] A fixed plate 24 is movably provided in the material storage trough 23, a telescopic rod 25 is fixedly connected to the back end of the fixed plate 24, a spring 26 is covered on the telescopic rod 25, a movable groove 231 is opened at the side end of the material storage trough 23, the telescopic rod 25 is fixed in the material storage trough 23, one end of the spring 26 is fixedly connected to the movable groove 231, and the other end thereof is fixedly connected to the fixed plate 24.

[0030] A finger groove 241 is provided at the upper end of the fixing plate 24 . The finger groove 241 is provided to facilitate the operator to insert a finger and use force to pull the fixing plate 24 outward, so that the ball 3 can be placed in the storage tank 23 more easily.

[0031] Specifically, the operator pulls the fixing plate 24 outward and puts the spheres 3 into the storage tank 23 one by one, and then releases the fixing plate 24. At this time, the spring 26 returns to its original state, and the telescopic rod 25 is stretched, so that the fixing plate 24 presses the spheres 3 tightly against the inner wall of the storage tank 23, ensuring that the spheres 3 are limited and fixed, and reducing the friction between the spheres 3 and the inner wall of the storage tank 23.

[0032] Working principle: When using the high-chromium ball storage and transfer device, the fixing plate 24 is pulled outward through the finger groove 241, and the balls 3 are placed in the storage trough 23 one by one until the storage trough 23 is full, and the fixing plate 24 is released. At this time, the spring 26 returns to its original state, and the telescopic rod 25 is elongated, so that the fixing plate 24 moves inward until the ball 3 is tightly pressed against the inner wall of the storage trough 23, thereby fixing and limiting the ball 3 and completing the storage of the ball 3. Then, the cart 1 is pushed by the push handle 13 so that the ball 3 can be transferred. When the ball 3 needs to be taken out, the end cover at the discharge port 22 is opened so that the ball 3 can fall into the collection frame 11 under gravity, which is convenient for the operator to collect.
