Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

As shown in fig. 1 to 4, the present application provides a bucket chain conveyor, which includes a housing and a bucket chain mechanism located in the housing, where the bucket chain mechanism includes a first sprocket 6, a second sprocket 5 and a chain 7 driven by the sprockets, that is, the chain 7 is sleeved on the first sprocket 6 and the second sprocket 5, and driven by the sprockets to rotate circularly, and a hopper for carrying material (for example, sand) is disposed on the chain 7 and moves along with the chain 7, so as to transport the material. The machine shell comprises a first shell 1 and a second shell 2 which are connected in a sliding mode, and the relative sliding direction of the first shell 1 and the second shell 2 is parallel to the conveying direction of the chain bucket mechanism, namely the direction of the hopper moving along with a chain 7 between a first chain wheel 6 and a second chain wheel 5. The conveying device comprises a first chain wheel 6 arranged on the first shell 1, a second chain wheel 5 arranged on the second shell 2, and a driving mechanism for driving the first shell 1 and the second shell 2 to slide relatively, so that when the first shell 1 and the second shell 2 slide relatively to each other to shorten the whole length of the shell through the driving mechanism, the first chain wheel 6 and the second chain wheel 5 approach each other; when the first housing 1 and the second housing 2 are slid relative to each other by the drive mechanism to extend the entire length of the housing, the first sprocket 6 and the second sprocket 5 are separated from each other. When the bucket chain conveyor needs to be moved, the whole length of the machine shell is firstly shortened, then the conveyor is moved and transported under the condition of the shortened length, and after the conveyor is transported to a destination, the machine shell is restored to the length which meets the using state (namely the working state of conveying materials) of the conveyor. Therefore, the chain bucket type conveying device can effectively solve the problem that the transportation is inconvenient due to the fact that the length is large.

For example, the second sprocket 5 is taken as a driving sprocket and the first sprocket 6 is taken as a driven sprocket in the present application, as shown in fig. 3, the motor 18 is installed on the outer wall of the second housing 2, and the motor 18 drives the second sprocket 5 to rotate. There are various alternative types of arrangements for the drive mechanism, for example, the present embodiment has the drive mechanism comprising a telescopic cylinder 3, in particular, the telescopic cylinder 3 may be a hydraulic cylinder or a pneumatic cylinder. In other embodiments, the driving mechanism may be provided as a rack and pinion mechanism as long as the first housing 1 and the second housing 2 can be driven to slide relatively in a direction parallel to the conveying direction of the bucket mechanism.

As shown in fig. 1, in the present embodiment, a cylinder block of the telescopic cylinder 3 is disposed in the first housing 1, and a movable rod of the telescopic cylinder 3 is connected to the second housing 2. Of course, the cylinder block may be provided in the second housing 2 and the movable rod may be connected to the first housing 1. In a particular practical application, the telescopic cylinder 3 is usually arranged outside the machine housing. In this embodiment, the cylinder base of the telescopic cylinder 3 is fixedly connected to the outer wall of the first housing 1, and the movable rod of the telescopic cylinder 3 is fixedly connected to the connecting plate 4 on the outer wall of the second housing 2.

In the transportation process of moving, the distance between first sprocket 6 and second sprocket 5 has been diminished when comparing with conveyor normal operating condition, and loose chain 7 rocks easily and strikes the casing, and for this reason, this application can make first casing 1 and/or second casing 2 be provided with straining device, and this straining device is used for offsetting with tensioning chain 7 with chain 7 including the support piece that is located the encirclement circle inboard of chain 7, support piece. That is, in the preparation stage of the carrying work, the entire length of the casing is shortened, and the chain 7 is prevented from being loosened by the support member of the tensioning mechanism to brace the chain 7 outward, so that the chain 7 can be prevented from being shaken. Furthermore, it will be readily appreciated that the tensioning mechanism may also function in normal operation of the conveyor to prevent misalignment of the rotating chain 7 with the sprocket.

The tensioning mechanism has various optional setting types, for example, in this embodiment, the tensioning mechanism includes a swing rod 12 hinged to the housing, a supporting member is disposed at an end of the swing rod 12, an elastic member is disposed between the swing rod 12 and the housing, and an elastic restoring force of the elastic member makes the supporting member always abut against the chain 7. As shown in fig. 1, when the first sprocket 6 and the second sprocket 5 approach each other, the swing link 12 automatically rotates clockwise by the tension spring 15 as an elastic member, and the support member at the upper end of the swing link 12 always abuts against the inner side of the chain 7. Of course, the elastic member may be provided in other forms, such as a torsion spring or a compression spring. In other embodiments, the tensioning mechanism may comprise a slider slidably connected to the housing, and the support member is fixedly connected to the slider, and the purpose of tensioning the chain 7 can also be achieved by moving the slider to bring the support member into contact with the inner side of the chain 7.

Because straining device's support piece is located the enclosure inboard of chain 7, so when straining device moved, the size of chain bucket mechanism perpendicular to transmission direction can the grow, for making straining device can move in bigger space, this application can make first casing 1 and/or second casing 2 be provided with the through-hole, and this through-hole is used for supplying the local casing that stretches out that chain 7 and bracing piece offset. In the embodiment, as shown in fig. 3 and 4, the first housing 1 is provided with a first through hole 16, and the second housing 2 is provided with a second through hole 17, referring to fig. 1, as the first housing 1 moves downward, the swing link 12 automatically rotates clockwise under the action of the tension spring 15, and at the same time, the first through hole 16 and the second through hole 17 coincide together, and the part of the chain 7 abutting against the support rod extends out of the first through hole 16 and the second through hole 17. On the contrary, in the process of restoring the original length of the casing, along with the upward movement of the first casing 1, the part of the chain 7, which is abutted against the supporting rod, is retreated into the casing again. In addition, the through hole exposes the inside of the machine shell, so that parts in the machine shell, such as the tensioning mechanism, can be conveniently overhauled.

Since the support part abuts against the chain 7 when the tensioning mechanism is actuated, in order to reduce the wear on the chain 7, the support part may include a body 13 and a rolling body 14 rotatably connected to the body 13, and the rolling body 14 abuts against the chain 7. As shown in fig. 1 and 2, in the present embodiment, the body 13 is a cylindrical rod, and the rolling element 14 is a cylinder rotatably fitted on the body 13. In other embodiments, the body 13 and the rolling bodies 14 may be provided in other forms, for example, the rolling bodies 14 may be provided as wheels.

As shown in fig. 1, the casing has a first side and a second side opposite to each other, the first side is provided with a feeding port, the second side is provided with a discharging port 11, specifically, the first casing 1 is provided with a feeding pipe 8 as the feeding port, and the second casing 2 is provided with a discharging pipe 9 as the discharging port 11. The first housing 1 is provided with a discharge opening at a position close to the bottom plate 19, through which material left in the housing and which is not normally conveyed out of the discharge pipe 9 can be conveniently cleaned. In order to automatically discharge the materials left in the casing, the material guide plate 10 located below the chain bucket mechanism may be disposed at the bottom of the casing, the material guide plate 10 is disposed obliquely with respect to the horizontal plane, and the material discharge opening is disposed corresponding to the lower end of the material guide plate 10, so that the materials falling from the chain bucket mechanism slide to the material discharge opening along the material guide plate 10, and the materials are prevented from being stacked in the casing. To facilitate the reintroduction of such discharged material from the feed pipe 8, the discharge opening and the feed opening are preferably located on the same side of the housing as the housing.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present application. Various modifications to the embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the application.
