DETAILED DESCRIPTION

[0029] In order to make those skilled in the art better understand the technical scheme of the present application, the present application will be further described in detail below with reference to the drawings.

[0030] Please refer to Figs. 1-3 , the auxiliary device for unloading, comprising:

[0031] The main support horizontal frame 1 is provided with the auxiliary horizontal frame 2 at the middle position, the auxiliary horizontal frame 2 is supported by the main support horizontal frame 1, and the main support horizontal frame 1 is the main support structure of the device;

[0032] The horizontal driven shaft 3 is horizontally arranged on the auxiliary horizontal frame 2 through bearings and is used as a power transmission shaft;

[0033] The winding wheel 4 is coaxially arranged on the horizontal driven shaft 3 and rotates axially with the horizontal driven shaft 3, and the winding wheel 4 is symmetrically distributed on the horizontal driven shaft 3 in two groups, and rotates axially in the same direction as the horizontal driven shaft 3 synchronously;

[0034] The oil rope 5 is wound on each group of winding wheels 4, and the oil rope 5 is connected to the iron shovel head of the iron shovel. The oil rope 5 is pre-wound on the winding wheel 4, and when the winding wheel 4 winds the oil rope 5, the oil rope 5 is used to pull the iron shovel connected to the iron shovel head. Therefore, in the specific use process, one person holds the iron shovel and pulls the iron shovel with the oil rope 5 to move to the appropriate position, inserts the iron shovel head into the grain position for unloading, and continuously applies force to the iron shovel downward, while the winding wheel 4 winds the oil rope 5 to pull the iron shovel head through the oil rope 5. The pulling force is the force of the iron shovel pushing the grain forward to unload or push the grain to the designated position. This pulling operation saves manual operation, improves work efficiency, reduces labor intensity of workers, and alleviates the problem of shortage of workers. The above operation is repeated to cycle the operation, and the worker holding the iron shovel can change position at any time to unload the grain;

[0035] The guide wheel set mechanism is arranged on the main support cross frame 1 in two groups, and the two groups of guide wheel set mechanisms are arranged one by one between the two groups of winding wheels 4. The oil rope 5 unwound from the winding wheel 4 passes through the guide wheel set mechanism to support and guide the change of direction of the oil rope 5 through the guide wheel set mechanism. Under the rolling support of the guide wheel set mechanism to the winding wheel 4, the oil rope 5 is not easy to separate from the winding wheel 4 when the winding wheel 4 winds and unwinds the oil rope 5, and the extension direction of the oil rope 5 can be easily changed. In turn, the worker holding the iron shovel can change position at any time to unload the grain, and the oil rope 5 can be supported and guided to change direction by the guide wheel set mechanism; and

[0036] The rotating drive mechanism is arranged on the main support cross frame 1 to drive the horizontal driven shaft 3 to rotate axially, and in turn to drive the winding wheel 4 to rotate, especially to drive the winding wheel 4 to rotate to wind the oil rope 5, instead of manually pulling the iron shovel to apply force.

[0037] Further, the main support cross frame 1 is symmetrically provided with two groups of supports 6 on the lower surface, and the lower end of the support 6 is provided with a moving wheel 7. The two groups of supports 6 are respectively located on both sides of the main support cross frame 1, and the device is more convenient to move through the moving wheel 7. In one specific implementation scenario, the grain needs to be conveyed to the designated location through a relatively long conveying belt. During this process, the worker needs to continuously unload the grain through the iron shovel or push the grain to the starting position of the conveying belt to enable the grain to be continuously conveyed to the designated location through the conveying belt. Fig. 2In the front view of the device shown, the device is across the top of the conveyor belt, so that the main support horizontal frame 1 is loaded above the conveyor belt, and the two groups of supports 6 on both sides play a limiting role to stably place the device on the conveyor belt. In order to stably place the device on the conveyor belt, the main support horizontal frame 1 and the support 6 can also be fixed by some conventional fixing means, such as steel wire rope tightening and fixing or sleeve, and fixed on the rigid idle position of the conveyor belt, and this is a conventional operation, which will not be repeated. After fixing the device, turn on the device, under the rolling support of the guide roller group mechanism to the oil wire 5, the two groups of oil wires 5 can be guided to the two sides of the conveyor belt, and then the grain on both sides can be conveniently pushed to the starting position of the conveyor belt.

[0038] Further, the vice horizontal frame 2 is provided with two groups of pressure rollers 8, which are correspondingly arranged between the two groups of winding wheels 4. The pressure roller 8 is pressed on the oil wire 5 wound on the winding wheel 4, so that the oil wire 5 is pressed on the winding wheel 4 under the relative rolling action between the pressure roller 8 and the winding wheel 4 and the oil wire 5 during the winding and unwinding of the winding wheel 4, so that the oil wire 5 is not easy to separate from the winding wheel 4 during the winding and unwinding, and the winding and unwinding is more stable.

[0039] Further, the guide roller group mechanism includes a vertical rectangular frame 9, and two groups of guide rollers 10 are symmetrically arranged on the vertical rectangular frame 9. The two groups of guide rollers 10 are arranged in parallel, and a gap is left between the two groups of guide rollers 10 for the oil wire 5 to pass through. The vertical rectangular frame 9 plays a supporting role for the two groups of guide rollers 10. The oil wire 5 passes through the gap between the two groups of guide rollers 10, and extends in the specified direction, and rests on the guide roller 10 on the corresponding side, and rolls relatively with the guide roller 10, so that the oil wire 5 can be wound and unwound freely, and the oil wire 5 is supported during the turning operation.

[0040] Further, the rotating drive mechanism includes a speed reducer 11, and the speed reducer 11 is fixedly arranged on the main support horizontal frame 1. The output shaft of the speed reducer 11 is parallel to the horizontal driven shaft 3.

[0041] The output shaft of the speed reducer 11 is provided with a driving sprocket 12, and the horizontal driven shaft 3 is provided with a driven sprocket 13. The driving sprocket 12 and the driven sprocket 13 are provided with a transmission chain 14 therebetween.

[0042] Specifically, the opening of the reduction motor 11 is controlled to drive the driving sprocket 12 to rotate, and then the driven sprocket 13 and the horizontal driven shaft 3 are driven to rotate through the transmission of the transmission chain 14, and then the winding wheel 4 is driven to rotate to wind the oil rope 5. Specifically, after the grain is pushed out by the shovel, the reduction motor 11 needs to be controlled to stop to stop winding the oil rope 5, and then stop pulling the shovel. Therefore, an electromagnetic clutch can be arranged on the output shaft of the reduction motor 11 to more accurately control the stop of the reduction motor 11, and an industrial remote controller can be arranged on the handle of the shovel to facilitate the control of the start and stop of the reduction motor 11 at any time.

[0043] Among them, the reduction motor 11 can be selected as a three-phase reduction 1.5-kilowatt motor.

[0044] Among them, the device can also be operated by one person, that is, a set of winding wheels 4 and oil ropes 5 are used to control a shovel. Therefore, the other set of winding wheels 4 and oil ropes 5 are not connected to the shovel or the oil rope 5 is directly unloaded from the winding wheel 4 for single-person operation.

[0045] Further, the main support cross frame 1 is provided with a U-shaped frame 15 on both sides for placing the shovel, which facilitates the movement of the device with the shovel.

[0046] Further, the main support cross frame 1 is provided with a protective cover 16, which is rotatably connected to the main support cross frame 1 through a hinge on one side. The protective cover 16 is provided with an avoiding opening 17 to expose only the guide wheel set mechanism and extend the oil rope 5 when the protective cover 16 is buckled above the main support cross frame 1. The protective cover 16 is used to protect the positions of the horizontal driven shaft 3, the winding wheel 4, the oil rope 5, the guide wheel set mechanism, and the rotating drive mechanism on the main support cross frame 1. Further, in order to prevent people from being injured by accidentally touching the above structure, the safety of the device is improved.

[0047] Among them, the electrical connection and use control of all electrical elements of the device are well known to those skilled in the art, and will not be described here.

[0048] As described above, during the process of winding the oil rope by rotating the winding wheel driven by the rotating drive mechanism, the device replaces the manual pulling of the shovel or the shovel, and the device can drive two shovels or shovels at the same time. The labor intensity of the workers is reduced, and the problem of shortage of workers is alleviated.

[0049] The above has only described certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
