Description

A mobile bulk grain cleaning equipment

Technical Field

The utility model relates to the field of bulk grain unloading, in particular to a mobile bulk grain vehicle clearing equipment.

Background Art

The basic operation process of bulk grain entering the granary is: the grain truck transports the bulk grain to the outside of the granary, and bulk grain conveying equipment is installed between the grain truck and the granary. The bulk grain conveying equipment includes multiple bulk grain conveyors arranged in a head-to-tail sequence.

In specific operations, the grain truck transports the bulk grain to the outside of the warehouse doors on both sides, and one of the bulk grain conveyors is placed next to the grain truck. The other bulk grain conveyors are connected end to end and extend all the way into the warehouse. When it is necessary to unload grain, the staff climbs onto the truck, opens the side of the grain truck, and pushes the bulk grain onto the bulk grain conveyor with a grain pushing tool. The bulk grain is then transported to the designated grain storage location in the warehouse through the bulk grain conveyors one level at a time.

That is to say, in the prior art, a manual grain unloading method is adopted in which bulk grain is manually pushed to a bulk grain conveyor. Manual grain unloading is also called manual vehicle clearing. This manual grain unloading method is not only time-consuming and labor-intensive, but also requires workers to stand on an unstable and easily collapsed grain surface to operate, which is very dangerous and poses a safety hazard.

Utility Model Content

The utility model aims to provide a mobile bulk grain truck cleaning device to solve the technical problems in the prior art that manual labor is required to stand on the grain truck to unload grain, which results in high labor intensity and potential safety hazards.

In order to solve the above technical problems, the technical solution of a mobile bulk grain cleaning equipment in the utility model is as follows:

A mobile bulk grain vehicle cleaning device comprises an equipment support with a walking mechanism at the bottom so as to be able to move forward and backward, a swivel support with a rotation axis extending in the up-down direction is rotatably mounted on the equipment support, the swivel support is driven by a swivel drive mechanism, a guide mechanism with a guide direction extending in the radial direction of the swivel support is arranged on the swivel support, an extension support is guided and moved on the guide mechanism, the extension support is driven by an extension support drive mechanism, a grain unloading auger is arranged on the extension support with one end for extending into a grain pile on a grain transport vehicle, the grain unloading auger is driven by the auger drive mechanism, and the grain unloading auger has a grain discharge section for transporting bulk grain to a bulk grain conveyor on the lower side.

Furthermore, the auger driving mechanism is connected to one end of the grain unloading auger, and the other end of the grain unloading auger is used to extend into the grain pile on the grain transport vehicle, and the grain discharge section is located between the two ends of the grain unloading auger.

Furthermore, the walking mechanism is a crawler-type walking mechanism.

Furthermore, the swivel bracket includes a square frame, and during the movement of the extension bracket, there is a stowage position for retracting the auger drive mechanism into the direction frame, and during the movement of the extension bracket, there is also an expansion position for moving the auger drive mechanism out from one side of the extension bracket.

Furthermore, the extending frame is provided with at least two door-pushing hydraulic cylinders spaced apart along the width direction of the square frame. The door-pushing hydraulic cylinder has a hydraulic cylinder piston rod whose axial direction is consistent with the moving direction of the extending frame. One end of the hydraulic cylinder piston rod is used to extend from one side of the direction frame to push the door of the grain truck.

Furthermore, a height adjustment mechanism is provided between the equipment support and the swivel support.

Furthermore, the height adjustment mechanism includes a telescopic bracket, which includes at least two telescopic sections that telescope and cooperate in the up and down directions in sequence. The telescopic sections are driven to telescope by a telescopic section driving mechanism. The lowermost telescopic section is connected to the equipment bracket through a telescopic section base, and the uppermost telescopic section is connected to the rotating bracket.

Furthermore, the telescopic joint base is hingedly connected to the equipment bracket, and a telescopic joint base driving mechanism for driving the telescopic joint base to swing left and right is arranged between the equipment bracket and the telescopic joint base.

The beneficial effects of the utility model are as follows: in the utility model, when the mobile bulk grain car-clearing equipment in the utility model is not unloading grain, the bulk grain car-clearing equipment can be moved and walked by the walking mechanism. During the moving and walking process, the length direction of the unloading auger is adjusted so that the length direction of the unloading auger is consistent with the moving direction of the bulk grain car-clearing equipment, so as to avoid the bulk grain car-clearing equipment having a large width. When it is necessary to unload grain, the bulk grain car-clearing equipment is moved to the side of the grain transport vehicle, the direction of the unloading auger is adjusted so that the axial direction of the unloading auger is consistent with the width direction of the grain transport vehicle, and then the bracket is extended to extend one end of the unloading auger into the grain pile of the grain transport vehicle. When the unloading auger works, the bulk grain in the grain pile can be transported to the grain discharge section. There is a bulk grain conveyor at the lower side of the grain discharge section, so as to realize the transportation of the bulk grain on the grain transport vehicle to the bulk grain conveyor. After completing the unloading of bulk grain at one position, the front and rear positions of the equipment bracket of the walking mechanism can be moved to unload another external bulk grain on the grain transport vehicle. In the present invention, the bulk grain on the grain transport vehicle is mechanically unloaded by using mobile bulk grain unloading equipment, thereby avoiding the technical problems of high labor intensity and unloading risks caused by manually climbing onto the grain transport vehicle to unload the grain.

DETAILED DESCRIPTION

In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

An embodiment of a mobile bulk grain cleaning device in the utility model is shown in Figures 1 to 9: it includes an equipment bracket 3 with a walking mechanism 2 at the bottom and capable of moving forward and backward, and the walking mechanism in this embodiment is a crawler-type walking mechanism. Item 1 in the figure represents the ground.

Four support legs 4 are arranged at the four corners of the equipment support 3. When in use, the support legs are unfolded by a hydraulic cylinder, and the bottom of the support legs cooperates with the ground support, thereby ensuring the stability of the equipment support.

The equipment support is rotatably equipped with a swivel support 16 whose rotation axis extends in the up-down direction. The swivel support 16 is driven by a swivel drive mechanism. In this embodiment, a height adjustment mechanism is arranged between the equipment support and the swivel support. The height adjustment mechanism includes a telescopic support 6. The telescopic support 6 includes at least two telescopic sections that are sequentially telescopically matched in the up-down direction. The telescopic sections are telescopically driven by the telescopic section drive mechanism. The lowermost telescopic section is connected to the equipment support 3 through the telescopic section base 5, and the uppermost telescopic section is connected to the swivel support 16. The telescopic section base is hingedly connected to the equipment support. The hinge axis of the telescopic section base extends in the front-back direction. A telescopic section base drive mechanism for driving the telescopic section base to swing left and right is arranged between the equipment support and the telescopic section base. The telescopic section base drive mechanism includes a left telescopic cylinder and a right telescopic cylinder arranged left and right. The left telescopic cylinder is extended, the right telescopic cylinder is retracted, and the telescopic section base can swing to the right (as shown in FIG8 ); the right telescopic cylinder is extended, the left telescopic cylinder is retracted, and the telescopic section base can swing to the left.

The telescopic joint base driving mechanism includes a height adjustment cylinder arranged between the telescopic joint base and the swivel bracket. When the piston rod of the height adjustment cylinder is extended, the swivel bracket can be raised to a certain height; when the piston rod of the height adjustment cylinder is retracted, the swivel bracket can be lowered to a certain height, thereby matching grain transport vehicles of different heights.

A slewing bracket gear ring is fixed on the slewing bracket, and the slewing drive mechanism includes a slewing drive motor. The slewing drive motor is arranged on the uppermost telescopic joint. A motor shaft gear that meshes with the slewing bracket gear ring is arranged on the motor shaft of the slewing drive motor. The diameter of the motor shaft gear is smaller than the diameter of the slewing bracket gear ring.

The swivel bracket is provided with a guide mechanism whose guiding direction extends radially along the swivel bracket. The guide mechanism is provided with an extension bracket for guiding movement. The extension bracket is driven by the extension bracket driving mechanism. The extension bracket is provided with a grain unloading auger 8 at one end for extending into the grain pile on the grain transport vehicle. The grain unloading auger is driven by the auger driving mechanism. The grain unloading auger has a grain discharge section 15 for transporting bulk grain to the bulk grain conveyor on the lower side.

In this embodiment, the swivel bracket includes a square frame 7, and during the movement of the extension bracket, there is a stowage position for retracting the auger drive mechanism into the direction frame, and during the movement of the extension bracket, there is also an expansion position for moving the auger drive mechanism out from one side of the extension bracket.

The guide mechanism includes at least two pairs of guide wheels 10 arranged on the inner wall of the square frame, the extension bracket guide movement is assembled between the corresponding guide wheels, a rack is fixed on the extension bracket, and the extension bracket driving mechanism includes an extension bracket driving motor arranged on the square frame, and a driving gear engaged with the rack is arranged on the power output end of the extension bracket driving motor. When the driving gear rotates forward, the extension bracket can move in the extension direction relative to the square frame, and when the driving gear rotates reversely, the extension bracket can move in the retraction direction relative to the square frame.

The auger drive mechanism is connected to one end of the grain unloading auger, and the other end of the grain unloading auger is used to extend into the grain pile on the grain transport vehicle, and the grain discharge section 15 is located between the two ends of the grain unloading auger. The auger drive mechanism includes an auger drive motor 12, which is transmission-connected to one end of the grain unloading auger.

The extending frame is provided with two door-pushing hydraulic cylinders 11 spaced apart along the width direction of the square frame. The door-pushing hydraulic cylinder 11 has a hydraulic cylinder piston rod whose axial direction is consistent with the moving direction of the extending frame. One end of the hydraulic cylinder piston rod is used to extend from one side of the direction frame to push the door of the grain transport truck.

When the bulk grain car cleaning equipment does not need to unload grain, the traveling mechanism can move the bulk grain car cleaning equipment forward and backward to move the position of the bulk grain car cleaning equipment. In this process, the axis of the grain unloading auger can be adjusted to the front and rear direction, thus avoiding the problem of the bulk grain car cleaning equipment being wide and having poor passability. When it is necessary to unload grain, the bulk grain car cleaning equipment can be moved to one side of the grain transport vehicle, and the axial direction of the grain unloading auger can be adjusted so that the axial direction of the grain unloading auger is along the width direction of the grain transport vehicle. Then the extension bracket is extended, and the hydraulic cylinder piston rod of the door hydraulic cylinder extends to the door (car side) of the grain transport vehicle, and then the door is opened. The hydraulic cylinder piston rod retracts, and the door is opened slowly to avoid the door opening suddenly, and the bulk grain is impacted everywhere. The end of the grain unloading auger away from the equipment bracket extends into the grain pile on the upper side of the grain transport vehicle, and the bulk grain conveyor is located at the lower side of the grain discharge section. The grain unloading auger works to transport the bulk grain from the upper side of the grain transport vehicle to the grain discharge section, and then falls onto the bulk grain conveyor and is transported to the warehouse by the bulk grain conveyor.

Some grain silos have slopes at the entrance to facilitate vehicle driving. If the grain truck is parked on the slope, the hood of the grain truck will not be horizontal but in a tilted position. At this time, the inclination angle of the telescopic joint base can be adjusted to ensure that the inclination angle of the telescopic joint base is consistent with the hood of the grain truck, which is convenient for adjusting the height of the grain unloading auger and facilitating the grain unloading operation.
