Description

Technical Field

[0001] The invention relates to the technical field of transport structures, in particular to a cargo loading and unloading platform. Background Art

[0002] The cargo loading and unloading platform, also known as the loading and unloading platform, unloading dock or cargo platform, is an indispensable part of the enterprise logistics process. It is mainly used to connect the cargo platform of the truck and the warehouse to save manpower and speed up loading and unloading.

[0003] The existing cargo loading and unloading platform is generally connected by a conveyor belt to the gap between the cargo platform and the collection box, which is convenient for conveying the cargo into the collection box. However, the existing cargo loading and unloading platform does not have the effect of automatically and evenly dispersing the cargo, and the scattered and piled cargo is not conducive to entering the collection box.

[0004] To this end, we propose a cargo loading and unloading platform. Summary of the invention

[0005] The object of the present invention is to provide a cargo loading and unloading platform to solve the problems raised in the above background technology.

[0006] The sprocket wheel is annularly fixed on the sprocket wheel, and the sprocket wheel is adjacent to the gear train of the belt conveyor, and the gear train is adjacent to the gear train of the belt conveyor, and the gear train is adjacent to the gear train of the belt conveyor.

[0007] Preferably, the shaking assembly includes a connecting rod fixedly connected to the two rotating plates, the connecting rod is pressed into engagement with the shaking rod, the shaking rod is L-shaped, and the end of the telescopic rod with a compression piece inside is fixedly connected to a ring sleeved on the connecting rod.

[0008] Preferably, the shaking assembly also includes a pressure rod rotatably connected to the central axis of the rotating plate, a sliding groove is opened on the inner side of the fixed frame, a sliding plate is slidably fitted in the sliding groove and presses against the pressure rod, and a compression spring is hung between the sliding plate and the end face of the sliding groove.

[0009] Preferably, the vertical dimension of the sliding groove is larger than the diameter of the pressing rod, so as to facilitate the movement of the pressing rod in the sliding groove and is not limited to the movement of the pressing rod in the horizontal direction.

[0010] Preferably, the movable component includes a first connecting plate fixedly connected to the rotating rod, the end of the first connecting plate is fixedly connected to a rotating shaft, the rotating shaft is rotatably connected to a second connecting plate rotatably connected to the pressure rod, and the fixed frame is also provided with an arc groove that slides with the rotating shaft, and the center of the arc groove is located to coincide with the position of the rotating rod.

[0011] Preferably, the rocking rods are distributed at intervals, and the extension line of the pushing rod is located between the two rocking rods, so that when the pushing rod acts on the rotating plate, the rocking rod will not act on the rotating plate.

[0012] Preferably, a connecting column is provided between the side of the belt and the chain, and the connecting column is located between the two shaking rods to avoid mutual interference between the shaking rods and the belt.

[0013] Preferably, a groove cooperating with the material receiving plate is provided on the edge of the rotating plate, and an elastic limit block is fixedly connected to the fixed frame and is in pressure contact with the rotating plate. The elastic limit block has a trapezoidal structure to ensure that the rotating plate is in a stable state when the rotating plate does not act on the pushing rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The goods enter the receiving plate through the belt. In this process, the connecting rods at intervals of multiple shaking rods cooperate with the compression parts in the telescopic rods to make the rotating plate reciprocate in the horizontal direction, thereby making the receiving plate reciprocate in the horizontal direction. Since the rotating rods move in the original position, the receiving plate makes an adaptive shaking movement up and down. This method ensures that the goods in the receiving plate are evenly distributed, making it easier for the goods to enter the collection box.

[0016] The horizontal movement of the rotating plate causes the second connecting plate to rotate, and the reciprocating range of the rotating rod is adjusted, thereby adjusting the reciprocating range of the telescopic rod and changing the shaking range, which helps to ensure that the goods in the receiving plate are evenly distributed;

[0017] When the belt rotates one circle, the push rod moves to the top and gets stuck in the movable groove, thereby driving the rotating plate to rotate. Through the action of the pushing column, the receiving plate is tilted at a large angle and enters the collection box to complete the collection of the goods. This method also has the function of quantitative collection, that is, the belt is unloaded after each rotation of one circle. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 12 The present invention provides a cargo loading and unloading platform, including a fixed frame 1 and a belt 2, chains 3 are arranged on both sides of the belt 2, and a receiving plate 4 cooperating with the belt 2 is arranged on the fixed frame 1; it also includes: a rotating plate 5 rotating with the fixed frame 1, a movable groove 6 is opened on the rotating plate 5, a pushing rod 7 slidingly cooperating with the movable groove 6 is arranged on the rotating shaft outside the chain 3, a shaking rod 8 acting on the receiving plate 4 is arranged on the rotating shaft inside the chain 3, a pushing column 9 cooperating with the bottom of the receiving plate 4 is fixedly connected to the edge of the rotating plate 5, and two fixed A rotating rod 10 is rotatably connected between the fixed frame 1, and a telescopic rod 11 is provided between the rotating rod 10 and the rotating plate 5 and is fixedly connected to the rotating rod 10; a shaking component, after the shaking component rotates one circle through the belt 2, the pushing rod 7 acts on the rotating plate 5 to rotate, so that the pushing column 9 acts to shake the receiving plate 4 up and down, and at the same time, the shaking rod 8 acts on the rotating plate 5 to make the rotating plate 5 shake horizontally; a movable component, the movable component causes the rotating plate 5 to move horizontally while driving the telescopic rod 11 to reciprocate, so that the receiving plate 4 shakes back and forth:

[0033] In the present application, the goods are placed on the belt 2 (a motor group driving member is provided below the belt 2, and the motor group driving member drives the belt 2 to rotate, so that the goods move up), so that the goods enter the receiving plate 4. In this process, the connecting rod 12 is acted on at intervals by a plurality of shaking rods 8, and the compression member in the telescopic rod 11 is cooperated to make the rotating plate 5 reciprocate in the horizontal direction, so that the receiving plate 4 reciprocates in the horizontal direction. Since the rotating rod 10 moves in the original position, the receiving plate 4 performs adaptive shaking movement up and down. This method ensures that the goods in the receiving plate 4 are evenly distributed, so that the goods can enter the collection box easily.

[0034] The horizontal movement of the rotating plate 5 causes the second connecting plate 20 to rotate (and helps the horizontal movement of the rotating plate 5), and the reciprocating movement of the rotating rod 10 is adjusted, thereby adjusting the reciprocating movement of the telescopic rod 11, and changing the shaking amplitude, which helps to ensure that the goods in the receiving plate 4 are evenly distributed;

[0035] When the belt 2 rotates one circle, the push rod 7 moves to the top and is stuck in the movable groove 6, thereby driving the rotating plate 5 to rotate 1 / 4. Through the action of the pushing column 9, the receiving plate 4 is tilted at a large angle and enters the collection box to complete the collection of the goods. This method also has the function of quantitative collection, that is, the belt 2 is unloaded after each rotation of one circle.

[0036] The shaking assembly includes a connecting rod 12 connected and fixed to the two rotating plates 5, the connecting rod 12 is pressed and matched with the shaking rod 8, the shaking rod 8 is L-shaped, and the end of the telescopic rod 11 with a compression member inside is fixedly connected to a ring 13 sleeved with the connecting rod 12; the shaking rods 8 are distributed at intervals, and the extension line of the push rod 7 is located between the two shaking rods 8;

[0037] The shaking assembly also includes a pressure rod 14 rotatably connected to the central axis of the rotating plate 5, a sliding groove 15 is provided on the inner side of the fixing frame 1, a sliding plate 16 is slidably matched in the sliding groove 15 and pressed against the pressure rod 14, and a compression spring 17 is hung between the sliding plate 16 and the end surface of the sliding groove 15;

[0038] In the present application, the belt 2 rotates continuously, driving the multiple shaking rods 8 to rotate, and the shaking rods 8 contact the connecting rods 12, pushing the connecting rods 12, making the connecting rods 12 move horizontally, making the pressing rods 14 slide in the sliding grooves 15, driving the slide plate 16 to move along the sliding grooves 15, and the compression springs 17 are compressed. When the shaking rods 8 pass over the connecting rods 12, the connecting rods 12 are reset under the action of the compression springs 17, so that the connecting rods 12 and the rotating plate 5 reciprocate, causing the receiving plate 4 to shake;

[0039] When the push rod 7 is inserted into the movable groove 6 (after the belt 2 rotates one circle), and then moves out of the movable groove 6, it drives the rotating plate 5 to rotate 1 / 4 circle, so that the push column 9 rotates and switches, acts on the receiving plate 4, makes the receiving plate 4 tilted at a large angle, enters the collection box, and completes the collection of goods.

[0040] The vertical dimension of the sliding groove 15 is larger than the diameter of the pressing rod 14 . The pressing rod 14 reciprocates in the sliding groove 15 . When the pressing rod 14 presses the slide plate 16 to reciprocate, the pressing rod 14 moves up and down along the slide plate 16 .

[0041] The movable assembly includes a first connecting plate 18 connected and fixed to the rotating rod 10, a rotating shaft 19 is fixedly connected to the end of the first connecting plate 18, a second connecting plate 20 rotatably connected to the pressing rod 14 is rotatably connected to the rotating shaft 19, and an arc groove 21 slidably matched with the rotating shaft 19 is also formed on the fixed frame 1, and the center of the arc groove 21 is located at the same position as the rotating rod 10;

[0042] In the present application, when the connecting rod 12 moves in the horizontal direction, the second connecting plate 20 is driven to move. Under the restriction of the arc groove 21, the rotating shaft 19 slides along the arc groove 21, the second connecting plate 20 rotates and the bottom of the second connecting plate 20 moves in the horizontal direction. The pressing rod 14 moves in the sliding groove 15, and the first connecting plate 18 reciprocates (the first connecting plate 18 reciprocates with the connecting rod 12 as the center of rotation);

[0043] When the first connecting plate 18 reciprocates, the telescopic rod 11 is driven to reciprocate, further causing the connecting rod 12 and the rotating plate 5 to shake.

[0044] A connecting column 22 is provided between the side of the belt 2 and the chain 3 . The connecting column 22 is located between the two shaking rods 8 to ensure that the belt 2 and the chain 3 move synchronously and avoid affecting the effect of the shaking rod 8 on the connecting rod 12 .

[0045] A groove 23 cooperating with the receiving plate 4 is provided at the edge of the rotating plate 5. When the rotating plate 5 rotates, the receiving plate 4 is driven to tilt at a large angle and shakes to facilitate the goods on the receiving plate 4 to fall into the collection box. An elastic limit block 24 that contacts the rotating plate 5 is fixedly connected to the fixed frame 1. The elastic limit block 24 has a trapezoidal structure.

[0046] When the push rod 7 does not enter the movable groove 6 and does not act on the rotating plate 5 during rotation, the rotating plate 5 is kept in this position by the elastic limit block 24;

[0047] When the push rod 7 enters the movable groove 6, the rotating plate 5 overcomes the friction effect of the elastic limit block 24 and drives the rotating plate 5 to rotate 1 / 4 circle. When the push rod 7 leaves the movable groove 6, the elastic limit block 24 presses and fixes the rotating plate 5 again, so that the rotating plate 5 remains stationary.
