DETAILED DESCRIPTION

[0025] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0026] like Figure 1-Figure 6 As shown, in the embodiment, a municipal fallen leaf collection device is provided, including a frame 1, and also including a leaf collecting component, a mud and sand separation component, a conveying component and a compression component arranged on the frame 1. The leaf collecting component includes a baffle 2, a rotating shaft 23, and a paddle 24. The baffle 2 is arranged on one side of the frame 1, and the rotating shaft 23 is rotatably connected in the baffle 2. A plurality of paddles 24 are evenly fixed on the rotating shaft 23. A feed port 21 is provided on one side of the baffle 2, and a discharge port 22 is provided on the other side of the baffle 2. A leaf collecting shovel 25 is connected to the bottom of the baffle 2. The leaf collecting shovel 24 is provided on the bottom of the baffle 2. 5 is connected to the feed port 21; the sediment separation assembly includes a separation box 31 and a screen 34, the separation box 31 is connected to the discharge port 22, the screen 34 is fixed inside the separation box 31, the transmission component includes a feed pipe 51 and a spiral feeding rod 52, the feed pipe 51 is tiltedly arranged on the frame 1, the spiral feeding rod 52 is rotatably arranged in the feed pipe 51, the lower end of the feed pipe 51 is connected to the separation box 31, the compression component includes a compression box 61 and a compression member, the upper end of the feed pipe 51 is connected to one side of the compression box 61, and the compression member is arranged in the compression box 61.

[0027] The device as a whole moves to collect fallen leaves that fall on the road surface. During the movement of the device, the fallen leaves come to the feed port 21 through the leaf collecting shovel 25, and the rotating shaft 23 drives multiple paddles 24 to rotate synchronously. The paddles 24 bring the fallen leaves from the feed port 21 into the shield 2. When the fallen leaves pass through the discharge port 22, they will enter the separation box 31 under the action of centrifugal force. After entering the separation box 31, the soil and sand adhered to the fallen leaves fall off in the separation box 31, pass through the screen 34 and fall to the bottom of the separation box 31, while the fallen leaves are above the screen 34, and the soil and sand are separated from the collected fallen leaves. The fallen leaves gathered in the separation box 31 are driven by the spiral feeding rod 52 in the fallen leaf feeding pipe 51, and enter the compression box 61 from the separation box 31. When the fallen leaves collected in the compression box 61 reach a certain amount, the compression member compresses the fallen leaves once to reduce the volume occupied by the fallen leaves in the compression box 61. After one compression, the compression box 61 continues to collect fallen leaves. Through multiple compressions, the space for accommodating fallen leaves is continuously squeezed out, thereby improving the collection efficiency of fallen leaves. The compression box 61 can collect and store as many fallen leaves as possible, reducing the number of times the device goes back and forth to the recovery point to unload fallen leaves, thereby improving the efficiency of fallen leaf collection.

[0028] Furthermore, a sand shield 33 is hingedly connected to the bottom of the separation box 31, and a plurality of protrusions 341 are fixed to the upper surface of the screen 34. When a large amount of soil and gravel is screened out of the separation box 31, the screened soil and gravel can be discharged by opening the sand shield 33 to reduce the weight of the vehicle. At the same time, the sand shield 33 can also be opened to a normally open state, so that the screened soil and gravel can be directly discharged out of the device.

[0029] Furthermore, the sediment separation assembly also includes a toggle member, which includes a driving motor 41, a driving shaft 35, a transmission shaft 38, a toggle rod 36, and a first transmission belt 37; the driving shaft 35 is rotatably connected to the screen 34, the driving shaft 35 passes through the screen 34 and extends to the top of the screen 34, and multiple toggle rods 36 are evenly fixed on the driving shaft 35; a worm 42 is fixed to the end of the power output shaft of the driving motor 41, a worm wheel 39 is fixed on the transmission shaft 38, the worm wheel 39 is meshed with the worm 42, and the first transmission belt 37 is sleeved outside the driving shaft 35 and the transmission shaft 38.

[0030] The driving motor 41 drives the worm wheel 39 to rotate through the worm 42, and then drives the rotating shaft to drive the transmission. The rotating shaft drives the transmission shaft 38 to rotate through the first transmission belt 37. The lever 36 on the rotating shaft also rotates accordingly. The fallen leaves recovered into the separation box 31 are disturbed by the rotating lever 36, so that the dirt, sand and other debris adhering to the fallen leaves fall off, which has the effect of separating the debris. At the same time, the top of the protrusion 341 is located within the rotation range of the lever 36. The rotating lever 36 will also hit the protrusion 341 when passing through the protrusion 341, thereby causing the screen 34 to vibrate intermittently, which can accelerate the dirt and sand falling from the fallen leaves to pass through the screen 34 and fall to the bottom of the separation box 31, improve the separation efficiency of dirt, sand and other debris, and reduce the probability of the screen 34 being blocked. The vibrating screen 34 can also drive the fallen leaves to vibrate and accelerate the separation of debris. A protection box may also be provided outside the first transmission belt 37 to prevent the first transmission belt 37 from being affected by sediment falling therefrom and affecting the transmission efficiency.

[0031] Furthermore, the leaf collecting component also includes a second transmission belt 43, a negative pressure fan 32 and an air duct 30; the second transmission belt 43 is sleeved on the power output shaft of the driving motor 41 and the outside of the rotating shaft 23; the negative pressure fan 32 is fixed to the inner top wall of the separation box 31, the input end of the negative pressure fan 32 is directly opposite to the discharge port 22, and the output end of the negative pressure fan 32 is connected to the material transfer pipe 51 through the air duct 30. The driving motor 41 also drives the rotating shaft 23 through the second transmission belt 43, and then recovers the fallen leaves by driving the paddle 24. Such a setting not only reduces the driving components, but also can realize leaf collection and leaf shifting with a single motor, and can also start or stop leaf shifting and leaf collection synchronously, which is beneficial to the operation and management of the equipment. The negative pressure fan 32 can generate negative pressure at the entrance of the separation box 31, attract the fallen leaves in the shield 2 to enter the separation box 31, and improve the efficiency of leaf collection. A dust and sand blocking device can be set at the air inlet end of the negative pressure fan 32 to avoid clogging of the poison tongue.

[0032] Furthermore, a plurality of air inlet holes 53 are provided on the upper surface of the feed pipe 51, a plurality of discharge holes 54 are provided on the lower surface of the feed pipe 51, a diffusion cover 55 is fixed on the upper surface of the feed pipe 51, the air inlet holes 53 are located inside the diffusion cover 55, and the other end of the air guide pipe 30 is connected to the diffusion cover 55. After the fallen leaves in the separation box 31 are separated from the debris by stirring and vibrating, they enter the compression box 61 through the feed pipe 51 under the action of the spiral feeding rod 52. The airflow blown out by the negative pressure fan 32 enters the diffusion cover 55 through the air guide pipe 30, and then enters the feed pipe 51 from the air inlet holes 53 to blow away the debris attached to the fallen leaves, and the blown debris can be discharged from the discharge holes 54 to the outside of the feed pipe 51 along with the airflow, further cleaning the fallen leaves and preventing the fallen leaves from being affected by the debris in subsequent use.

[0033] Furthermore, the compression member includes a cylinder 63 and a pressure plate 65; a plurality of blocks 64 are arranged on the inner side wall of the compression box 61 from top to bottom, an upward accommodating chamber 62 is arranged on the inner top of the compression box 61, the cylinder 63 is arranged in the accommodating chamber 62, a plurality of pressure plates 65 are arranged in the compression box 61, a plurality of pressure plates 65 are stacked up and down, and the pressure plates 65 are clamped on the blocks 64. The fallen leaves enter the compression box 61 for storage. When the fallen leaves are stored to a certain amount and occupy a large amount of space, the cylinder drives a pressure plate 65 to descend to compress the fallen leaves in the compression box 61. The block 64 arranged on the inner wall of the compression cylinder is a block arranged in a right triangle, which has a certain elasticity, and its bottom is a horizontally arranged edge. Such an arrangement can clamp the pressure plate 65, and the pressure plate 65 can press over the block 64 when moving downward, and the straight edge at the bottom of the block 64 can prevent the pressure plate 65 from moving upward. Such an arrangement enables the pressure plate 65 to achieve a one-way movement effect. After the compression and bending, the cylinder 63 rises and retracts, and the pressing plate 65 is clamped on the clamping block 64 to compress the fallen leaves. The internal space of the compression box 61 is released, and the fallen leaves can continue to be collected and stored, thereby increasing the storage space.

[0034] Furthermore, a through hole 67 is provided in the middle of the pressing plate 65, and a spacer 66 is provided on the top of the pressing plate 65 for maintaining the distance between adjacent pressing plates 65. The spacer 66 allows a certain distance between the pressing plates 65, and the through hole 67 allows the free end of the cylinder 63 to pass through, so as to facilitate pushing each pressing plate 65 in turn.

[0035] Furthermore, a pushing piece is provided at the free end of the cylinder 63, and the pushing piece includes a pressure sensor 60, a mounting block 68 and a push plate 69. The pressure sensor 60 is fixed to the free end of the cylinder 63, and the mounting block 68 is fixed to the bottom of the pressure sensor 60. Mounting grooves are provided at the lower ends of both sides of the mounting block 68. The push plate 69 is rotatably connected in the mounting groove, and a torsion spring is also provided between the push plate 69 and the mounting block 68. In the initial state, the cylinder 63 brings the push piece to the bottom of the bottom plate 65 through the through hole 67. When compression is required, the cylinder 63 rises with the compression piece, and the pressure sensor 60 and the mounting block 68 pass through the through hole 67 in turn. The push plate 69 also retracts inwards and passes through the through hole 67 under the restriction of the through hole 67. After passing through the through hole 67 of the bottom plate 65, the push plate 69 is no longer restricted by the through hole 67 and opens outwards under the action of the torsion spring. At this time, the push piece is located above the bottom plate 65, and the area of ​​the push plate 69 after opening exceeds the through hole 67. The cylinder 63 moves downward, and the push plate 69 presses on the upper surface of the bottom plate 65. At this time, the plate 65 can be pressed down on the fallen leaves for compression. The pressure sensor 60 is used to detect the force of compressing the fallen leaves, and then the degree of compression of the fallen leaves can be grasped, and the timing of stopping the cylinder 63 pressing down can be judged in turn.

[0036] When compression is complete, Figure 7 As shown, the cylinder 63 rises with the pusher, and the pusher moves to the top of another pressing plate 65 through the above method. After a certain amount of fallen leaves are collected, the above steps are repeated for the second compression. In this way, multiple compressions of fallen leaves can be achieved in the compression box 61, and space for storing fallen leaves can be continuously squeezed out. In this way, the amount of fallen leaves collected and stored is increased, the number of times the equipment goes back and forth to the collection point to unload fallen leaves is reduced, and the efficiency of fallen leaf collection is improved.

[0037] Furthermore, the inner bottom wall of the compression box 61 is inclined, and a material taking port is provided at the lower end of the side wall of the compression box 61, and a sealing plate is hinged on the material taking port. When the fallen leaves in the compression box 61 are fully collected, the fallen leaves can be taken out through the material taking port. After the sealing plate is opened, the cylinder 63 continues to press down, and the fallen leaves will be discharged from the material taking port. At the same time, each pressing plate 65 can be lowered to the material taking port for taking out, which is convenient for rearranging the device to carry out the leaf collecting operation again.
