Technical Field
The invention belongs to the technical field of animal husbandry machinery, and particularly relates to a dung collection box sliding mechanism of a dung collection vehicle for a cattle farm.
Background
At present, when a dung collection vehicle of a cattle farm works, cattle dung is lifted by a lifting conveyor and falls into a dung collection box, when the dung collection box is full, the cattle dung is conveyed to a designated place, the front end of the dung collection box is lifted, and the dung is discharged from the rear end of the dung collection box. Because the elevator is positioned at the upper part of the manure collecting box and can limit the lifting of the front end of the manure collecting box, when the manure is dumped, the elevator must be moved out of the upper part of the manure collecting box at first, so that the process is multiple, the operation is complicated, and the failure rate is high.
Disclosure of Invention
In order to overcome the defects of the cattle farm dung collection vehicle in the using process, the invention provides a sliding mechanism of a dung collection box of the cattle farm dung collection vehicle, and the working efficiency of the dung collection vehicle is improved.
In order to achieve the purpose, the invention provides the following technical scheme: a dung collection box sliding mechanism of a dung collection vehicle for a cattle farm comprises a frame, a lifting conveyor, a dung collection box, a rear limiting block, a swing arm, a front limiting block, a lifting oil cylinder, a lower sliding block and an upper sliding block. The excrement collecting box is positioned above the rack, the elevator is positioned at the upper part of the front end of the excrement collecting box, the lifting oil cylinder is positioned at the middle position of the front end of the excrement collecting box, the upper end of the lifting oil cylinder is hinged with the excrement collecting box, the lower end of the lifting oil cylinder is hinged with the rack, the upper sliding block and the lower sliding block are symmetrical pieces, four pieces are totally arranged, every two pieces are in one group, the lifting oil cylinder is welded at the front ends of the excrement collecting box and the rack in a staggered mode, the two upper sliding block inclined planes can slide up and down along the two lower sliding block inclined planes, the swing arm is provided with two pieces, the lifting oil cylinder is symmetrically positioned at the rear part of the excrement collecting box, the upper end of the lifting oil cylinder is hinged with the excrement collecting box, the lower end of the lifting oil cylinder is hinged with the two front stoppers, the two front stoppers are welded on the rack, the rear stopper is provided with two pieces, the rear end of the swing arm corresponds to the swing arm and is welded on the rack at a certain distance from the swing arm, and when the swing arm is inclined backwards to the rear stopper, the swing arm coincides with the upper inclined plane of the rear stopper. The front limiting stopper consists of two hinged lugs and a baffle, the baffle is welded at the upper part of the front end of the two hinged lugs and is connected with the two hinged lugs, and when the two swing arms are in a vertical state, each swing arm is respectively close to one baffle.
The invention has the beneficial effects that: clear dung-cart collection excrement case glide machanism can realize that collection excrement case freely dumps excrement and urine, guarantees simultaneously that collection excrement case during operation by the stability when rising, descending and dumping excrement and urine, has reduced because of the fault rate that produces when collection excrement case dumps excrement and urine. When the lifting oil cylinder starts to work, the upper sliding block slides backwards and downwards along the lower sliding block, the height of the excrement collecting box is reduced, the excrement collecting box is moved out from the lower part of the elevator, the upper sliding block and the lower sliding block are used, the excrement collecting box is guaranteed to be stably moved, meanwhile, the safety of the lifting oil cylinder is guaranteed, and the service life of the lifting oil cylinder is prolonged. Meanwhile, the two swing arms rotate clockwise around the hinge point along with the backward and downward sliding of the manure collecting box, when the swing arms rotate to be overlapped with the upper inclined plane of the rear limiting block, the swing arms stop rotating, at the moment, the inclined planes of the upper sliding block and the lower sliding block are completely overlapped, the manure collecting box is also completely moved out from the lower part of the elevator and descends to the lowest point (as shown in figure 5), when the manure collecting box descends to the lowest point, the lifting oil cylinder continues to work, at the moment, the two swing arms are limited by the rear limiting block and are still, and the manure collecting box rotates by taking the upper hinge point of the swing arms as a rotating point, so that the front end of the manure collecting box is lifted to the highest point (as shown in figure 6). The use of back spacing piece has guaranteed that two swing arms when clockwise rotating to the maximum angle, can not continue to rotate because of inertia, and swing arm hinge joint can not receive the impact, has improved its life. After the excrement and urine dumps and finishes, the lift cylinder contracts, the front end of the excrement collection box rotates downwards, the two swing arms rotate anticlockwise, after the upper sliding block is contacted with the lower sliding block, the lift cylinder continues to contract, the two swing arms rotate anticlockwise, the two upper sliding block inclined planes slide along the two lower sliding block inclined planes, the excrement collection box moves upwards forwards, when the two swing arms rotate to the position vertical to the frame, the lower ends of the two swing arms are respectively abutted to the baffles on the two front limiting devices and are blocked by the baffles to stop rotating, the lift cylinder stops working, and at the moment, the front end of the excrement collection box is just located at the position below the elevator (figure 1). The use of the front limiting stopper ensures that the two swing arms are blocked by the baffle after rotating anticlockwise to vertical positions, cannot rotate continuously under the action of inertia, ensures that the stable return and the hinged part of the excrement collecting box are not impacted, and prolongs the service life of the excrement collecting box. The use of the upper sliding block, the lower sliding block, the front limiter and the rear limiting block ensures that the excrement can be freely dumped by the excrement collecting box, and the failure rate generated when the excrement is dumped by the excrement collecting box is greatly reduced.
