When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0029] The present invention provides the following embodiments:

[0030] Example 1: The present invention provides a material transfer and crushing device for construction engineering, such as Figures 1-8As shown, it includes a transfer vehicle 1, a transfer shell 2 is installed at the upper end of the transfer vehicle 1, a storage shell 6 is installed at the front end of the transfer shell 2, and several hydraulic cylinders are installed between the lower end of the transfer shell 2 and the upper end of the transfer vehicle 1. A support shaft is provided on the rear side of the transfer vehicle 1, and support hinge seats 32 are respectively provided on the left and right sides of the support shaft. The support hinge seats 32 are respectively arranged on the left and right sides of the lower end of the transfer shell 2, and a transfer cavity 5 is provided at the upper end of the transfer cavity 5. The rear side of the transfer cavity 5 is rotatably connected with a flip plate 3, a cover plate 1 4 is provided on the front side of the upper end of the transfer cavity 5, and a cover plate 2 9 is provided on the rear side of the upper end of the transfer cavity 5. A crushing mechanism and a screening mechanism are installed on the transfer shell 2, and the screening mechanism is connected to the driving mechanism. The driving mechanism is installed on the outside of the storage shell 6, and the driving mechanism is correspondingly connected to the power mechanism, and the power mechanism is connected to the transfer vehicle 1.

[0031] The working principle of the above technical solution is:

[0032] The transfer vehicle 1 is used to drive the transfer shell 2 to move. The transfer chamber 5 of the transfer shell 2 is used to store the sand and gravel after mining. The arrangement of several hydraulic cylinders makes the connection between the transfer vehicle 1 and the transfer shell 2 equivalent to a dump truck, which is convenient for unloading. A positioning pin is set between the flip plate 3 and the transfer shell 2. When unloading, the positioning pin between the flip plate 3 and the transfer shell 2 is pulled out. When the transfer shell 2 drives the support hinge seat 32 to rotate around the support shaft, the flip plate 3 can rotate along the transfer shell 2 under the push of the sand and gravel, so that the sand and gravel leave the transfer chamber 5, completing the unloading of the sand and gravel. A crushing mechanism is installed on the transfer shell 2 for crushing the sand and gravel loaded into the transfer chamber 5, and then the screening mechanism is driven to work by the driving mechanism. The setting of the power mechanism can use the power when the transfer vehicle 1 moves to drive the driving mechanism. The movable mechanism works, and the screening mechanism screens the crushed sand and gravel so that the sand and gravel size reaches the target size. The above-mentioned crushing and screening processes can be carried out simultaneously in the process of the transfer vehicle 1 transporting the sand and gravel. There is no need to transport the sand and gravel to the processing plant for crushing and then transport it to the construction area, which saves time and is conducive to improving the construction efficiency of the construction project. It solves the technical problem that the crushing process is added between the mining and transportation processes, which consumes time and reduces the construction efficiency of the construction project. The arrangement of the cover plate 1 4 and the cover plate 2 9 makes the transfer chamber 5 a closed chamber, which prevents the dust generated in the sand and gravel crushing process from affecting the external environment and nearby personnel, and solves the technical problem that a large amount of dust generated in the sand and gravel crushing process will pose a threat to the health of the operators and is not conducive to environmental protection.

The rotating disks 59 on the left and right sides are rotatably connected to the sliders 35 on the left and right sides in a one-to-one correspondence. The slider 35 on the left is fixedly connected to the telescopic cylinder 1 39, and the matching block 40 on the right is fixedly connected to the motor 1 36 through the motor shaft. The slider 35 on the left is slidably arranged at the front end of the storage shell 6, and the slider 35 and the motor 1 36 on the right are both fixedly arranged at the front end of the storage shell 6, and the telescopic cylinder 1 39 is fixedly connected to the mounting block 2 46;

When the sector gear 48 meshes with the lower rack 1 49, it drives the lower rack 1 49 to move in the opposite direction. At this time, the sector gear 48 cannot mesh with the upper rack 1 49. The lower rack 1 49 drives the connecting block 2 47 to move in the opposite direction. The rotation of the sector gear 48 can drive the connecting block 2 47 to move back and forth in the front and rear directions, and the connecting block 2 47 drives the rack 2 41 to move back and forth, thereby achieving the purpose of synchronously driving the rack 2 41 to move back and forth in the front and rear directions when the front wheel power shaft 20 rotates. There is no need to apply additional driving force to the rack 2 41 for driving, which saves energy.

[0039] When the gear 2 is in the state of rotation, the gear 2 is rotated by the gear 2 and the gear 2 is rotated by the gear 2.

The crushing plate 26 can also provide a driving force for the sand and gravel in the process of crushing the sand and gravel, pushing the sand and gravel to move toward the crushing channel 53. When the sand and gravel in the transfer chamber 5 passes through the crushing channel 53, the motor 2 17 is started, the motor 2 17 drives the gear 4 18 to rotate, the gear 4 18 drives the upper gear 3 23 to rotate, and the upper gear 3 2 3 drives the gear three 23 on the lower side to rotate, and the gear three 23 on the upper and lower sides rotate in opposite directions, and the gear three 23 drives the crushing rollers 25 on the upper and lower sides to rotate through the connecting shaft three 24.

When the push plate 1 30 rotates reciprocatingly from a horizontal state to a vertical state, the screen plate 29 can be pushed to slide upward along the sliding cavity 7 during the rotation of the push plate 1 30. When the screen plate 29 moves upward, the inclined block 60 thereon slides along the lower inclined end of the baffle 31, pushing the baffle 31 to rotate toward the transfer cavity 5. During the rotation of the baffle 31, the sand and gravel on the screening plate 29 can be pushed to gather toward the mesh position. When the baffle 31 is in a horizontal state, the baffle 31 cannot The mesh area on the screening plate 29 corresponds to the mesh area, which reduces the amount of sand and gravel falling on the baffle 31. When the push plate 1 30 rotates from a vertical state to a horizontal state, the screening plate 29 moves downward under the action of gravity, thereby achieving the purpose of the up and down movement of the screening plate 29. The up and down movement of the screening plate 29 can vibrate and screen the sand and gravel so that the sand and gravel reach the target size, thereby improving the screening efficiency of the sand and gravel. The setting of the baffle 31 prevents the sand and gravel in the transfer chamber 5 from falling into the outside through the sliding chamber 7. During the rotation of the pushing plate 1 30, the sand and gravel passing through the screening plate 29 falls into the bottom of the transfer chamber 5 and the storage chamber 58. When the gear 6 44 rotates back and forth, it drives the rack 3 42 to move back and forth. The rack 3 42 drives the pushing block 51 to move back and forth through the fixed block 50, and the pushing block 51 drives the pushing block 51 to move back and forth. The movable plate 2 55 moves back and forth, and the pushing plate 2 55 moves the sand and gravel falling in the transfer chamber 5 to the lower end of the pushing plate 28 through the return channel to prevent the accumulation of sand and gravel from affecting the rotation of the pushing plate 1 30, and in the process of pushing the pushing plate 1 30, the setting of the limit block 57 prevents the pushing plate 2 55 from rotating forward, and the pushing plate 2 55 cannot rotate to a horizontal state when rotating backward, so that the pushing plate 2 55 is in a vertical state as much as possible when pushing the sand and gravel, increasing the contact area between the sand and gravel and the pushing plate 2 55, and when the sand and gravel contact the lower inclined end of the pushing plate 28, it can assist in pushing the pushing plate 28 upward until the sand and gravel at the upper end of the pushing plate 28 is crushed. After the transfer vehicle 1 moves to the construction area, the pushing plate 28 moves to the upper end of the pushing plate 28. On the other side, unloading begins, and the transfer shell 2 rotates around the support shaft. The sand and gravel that have completed screening in the transfer chamber 5 flows out of the transfer chamber 5 under the action of gravity. The sand and gravel in the storage chamber 58 drives the push plate 2 55 to rotate backward under the action of gravity, so that the push plate 2 55 changes from a vertical state to a horizontal state, and the sand and gravel in the storage chamber 58 is sent to the outside through the transfer chamber 5. When the transfer shell 2 reaches the maximum inclination angle, the maximum opening and closing angle of the flip plate 3 and the transfer shell 2 and the setting of the cover plate 2 9 ensure that the sand and gravel remaining on the upper side of the push plate 28 cannot flow out of the transfer chamber 5, so that the above-mentioned sand and gravel flowing out of the outside are all located on the lower side of the push plate 28, thereby completing the crushing and transfer steps of the sand and gravel. If there is sand and gravel that cannot pass through the screening plate 29 remaining on the screening plate 29 at this time,The transfer shell can be kept in an inclined unloading state, and the motor 2 17 can be controlled to reverse, thereby changing the direction of the upper and lower crushing rollers 25, so that the sand and gravel slide down between the upper and lower crushing rollers 25 under the action of gravity and are crushed again. At the same time, the screening plate 29 can be kept moving up and down until the sand and gravel that does not reach the target size are crushed again and fall on the upper side of the push plate 28. The protrusion 27 is controlled to rotate in the opposite direction, so that the push plate 28 moves downward and returns to its original position. The sand and gravel on the upper side of the push plate 28 is discharged to another accumulation area. After a sufficient amount of sand and gravel is accumulated, it can be crushed in a centralized manner or loaded into the transfer chamber 5 for further crushing and screening.
