DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0022] like Figures 1 to 5 As shown, the embodiment of the utility model discloses a movable material guide trough, including a detachable column and a main beam structure, the main beam structure and the top of the column are connected by bolts, and a first wear-resistant plate 6 is provided at the connection between the two, the bottom of the column and the top of the position adjustment mechanism are connected by bolts, and a second wear-resistant plate 10 is provided at the connection between the two, the position adjustment mechanism is connected to the intermediate frame body, and the height of the column matches the height of the roller. The movable material guide trough of the utility model that can be adjusted in the material receiving section area can solve the problem of the on-site opening of the material guide trough, and is convenient for on-site installation and adjustment. In addition, the material guide trough can be moved during the maintenance of the roller without being dismantled, which greatly saves the maintenance time and reduces the difficulty of maintenance.

[0023] Furthermore, a guide trough with the same structure is provided on both sides of a section of rollers, and the main beam structure includes a first steel plate 1, a first H-shaped steel 2, a second steel plate 3 and a third steel plate 5. The first steel plate is connected to the end of the first H-shaped steel, and the end of the first steel plate is overlapped on the upper belt of the belt conveyor through a locking device and a sealing mechanism. The first steel plate serves as a side plate of the guide trough, and the other end of the first H-shaped steel is connected to the second steel plate, and the bottom end of the second steel plate is connected to the third steel plate. The bottom of the third steel plate is provided with a screw hole connected to the column. The main beam structure can use different steel sections according to the specific stress conditions, and can also be welded to form a box-type main beam structure, or it can be symmetrically welded into a box-type with double-channel steel, which needs to be specifically calculated and determined according to the stress size and the overall structure length.

[0024] Furthermore, the main beam structure also includes a round steel 4, which is arranged at the connection between the second steel plate and the third steel plate. When the roller is repaired or adjusted with the upstream slide pipe, the round steel and the upper and / or downstream main beam structure are connected through an external connecting steel plate. Specifically, the heavy main beam structure is used as a temporary support during the replacement of the roller, and at the same time, the overall structure is more stable in the movable performance of the receiving section. During the maintenance of the roller, the column position can be moved without the need for overall disassembly. It breaks the previous situation that the side columns of the guide trough need to be disassembled during the maintenance of the guide trough and the roller. The heavy main beam is used to support the overall structure, and the length of the guide trough can be adapted by increasing the model of the main beam profile. If the length of the guide trough is relatively long, it can be connected to the front and rear guide troughs in a hinged form during maintenance to achieve the effect of overall support. Specifically, during the maintenance process, the connection of the front section, middle section, and rear section of the guide trough is bolted to achieve the purpose of connecting and supporting the overall structure when the columns on both sides are moved.

[0025] Furthermore, the first wear-resistant plate and the main beam structure are connected via countersunk screws.

[0026] Furthermore, the column includes a second H-shaped steel 8 and a fourth steel plate 7 and a fifth steel plate 9. The fourth steel plate and the fifth steel plate are respectively connected to the upper and lower parts of the second H-shaped steel. The fourth steel plate is provided with a long hole according to the bolt specifications, and the fifth steel plate is provided with a round hole for installing the second wear-resistant plate. The upper end of the column on the side of the guide trough is connected to the main beam structure in a movable manner. The main beam adopts a structure in which a long hole is opened in the steel plate at the position where it is connected to the column, so that the bolts of the column can be moved during adjustment, and the range of position movement can be within the distance of a group of rollers. In this way, when the rollers are inspected and replaced, it is not necessary to remove the column, but to move the entire section of the guide trough.

[0027] Furthermore, the second wear-resistant plate and the fifth steel plate are connected via countersunk screws.

[0028] In this embodiment, the first wear-resistant plate and the second wear-resistant plate are both made of high molecular polymer wear-resistant material.

[0029] Furthermore, the position adjustment mechanism includes a sixth steel plate 11, a seventh steel plate 12 and an eighth steel plate 13, the sixth steel plate is connected to the bottom end of the column, the seventh steel plate is provided with a long hole, the size of the long hole is determined by the size of the connecting bolt, the length of the long hole is determined by the removal size of a group of rollers of a specific roller, and the eighth steel plate is vertically connected between the seventh steel plate and the intermediate frame body. The column can be moved in the long circular hole in the slide groove of the position adjustment mechanism to facilitate the precise adjustment of the downstream belt conveyor in the material receiving area, saving the time of opening holes on the existing guide trough. The eighth steel plate is connected to the intermediate frame body with bolts, and the bolt hole is determined by the size of the bolt.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
