DETAILED DESCRIPTION

[0025] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] An anti-dumping trailer unloading device, such as Figure 1-7 As shown, it includes a moving frame 1, a mounting plate 2 and a cylinder 3; the moving frame 1 is rotatably connected to two mounting plates 2 that are symmetrically arranged in the front and back; the moving frame 1 is rotatably connected to two cylinders 3; the telescopic ends of the cylinders 3 are rotatably connected to the corresponding mounting plates 2 respectively;

[0028] It also includes a transmission shaft 4, a pedal 5, a gear 6, a rack 7, a cylinder 2 8, a cylinder 3 21, a mounting plate 22 and a sealing plate 23; a number of transmission shafts 4 are equidistantly connected to the two mounting plates 2; a pedal 5 is fixedly connected to each transmission shaft 4; each pedal 5 is located between the two mounting plates 2; a gear 6 is fixedly connected to the front part of each transmission shaft 4; a rack 7 is slidably connected to the front mounting plate 2; a cylinder 2 8 is fixedly connected to the front mounting plate 2; the telescopic end of the cylinder 2 8 is fixedly connected to the rack 7; all the gears 6 are meshed with the rack 7; two cylinders 3 21 are fixedly connected to the two mounting plates 2 respectively; the telescopic ends of all cylinders 3 21 on the same mounting plate 2 are commonly fixedly connected to a mounting plate 2 22; a number of sealing plates 23 are welded equidistantly between the two mounting plates 22; each sealing plate 23 is located between the two pedals 5.

[0029] Furthermore, in order to increase the friction between the artificial foot and the pedal 5, a groove is provided on the upper side of the pedal 5, and a smooth surface is provided on the lower side of the pedal 5.

[0030] Furthermore, in order to slow down the cargo, a convex point is provided on the lower side of the rightmost pedal 5 .

[0031] Furthermore, in order to facilitate the sealing plate 23 to be inserted between two adjacent pedals 5, the upper left and upper right portions of the pedals 5 are both beveled.

[0032] The first step: connect cylinder 1 3 and cylinder 2 8 to an external air pump, control cylinder 1 3 to start and drive the left part of mounting plate 2 to rise, so that the leftmost pedal 5 is at the same height as the trailer cargo board, manually push the mobile frame 1 to the side of the trailer, and mount the left part of mounting plate 2 on the trailer cargo board, so that the leftmost pedal 5 is close to the trailer cargo board, and then lock the moving wheels at the bottom of the mobile frame 1 to prevent the mobile frame 1 from moving. At this time, the worker can walk between the trailer and the ground through the pedal 5 to unload the goods.

[0033] Step 2: Control the cylinder 2 8 to drive the rack 7 to move, and the rack 7 drives the gear 6 to drive the transmission shaft 4 and the pedal 5 to rotate and turn over, so that the pedal 5 turns over to the position shown in the figure. Figure 6 In the state shown, all the pedals 5 together form a continuous flat slide, and the smooth surface of the pedals 5 faces upward to facilitate the sliding of goods. At this time, workers can directly place bagged fertilizers, bagged grains, boxes and other goods on the pedals 5, and the goods slide down under their own gravity to assist in unloading.

[0034] Step 3: After the pedal 5 is turned over, there is a gap between two adjacent pedals 5, which causes the corners of the box to be easily stuck in the gap when the box slides on the pedal 5 during the unloading of the auxiliary box cargo, blocking the slideway, thereby affecting the smooth passage of subsequent cargo. At the same time, when the box slides on the pedal 5, the corners of the box come into contact with the gap, and the box is affected by the sliding inertia of the box, and there is a risk of the box rolling down along the pedal 5, which is likely to cause damage to the box and the cargo inside the box. Therefore, when the pedal 5 is turned over to the position shown in FIG. Figure 6 After the state shown, the control cylinder 3 21 drives the mounting plate 22 and the sealing plate 23 to move upward, so that the sealing plate 23 is inserted between two adjacent pedals 5, as shown in FIG. Figure 6-7 As shown, the gap between two adjacent pedals 5 is blocked by a sealing plate 23, thereby preventing the corners of the box from getting stuck in the gap, thereby avoiding the problem of goods blocking the slide and causing damage to the goods.

[0035] Example 2

[0036] On the basis of Example 1, Figure 4-7 As shown, it also includes a mounting rod 31, a sliding sleeve 32 and a protective rod 33; a mounting rod 31 is welded to the upper left part and the upper right part of each mounting plate 2; each mounting rod 31 is connected to a sliding sleeve 32; a protective rod 33 is commonly connected between the two front sliding sleeves 32; another protective rod 33 is commonly connected between the two rear sliding sleeves 32.

[0037] Furthermore, it also includes bolts 34; each mounting rod 31 is provided with a plurality of mounting holes 31a at equal intervals; each mounting rod 31 is slidably connected with a corresponding sliding sleeve 32; each sliding sleeve 32 is provided with a bolt 34; each sliding sleeve 32 is fixed to the mounting rod 31 by means of the corresponding bolts 34 and mounting holes 31a.

[0038] Furthermore, it also includes a clamping rod 35 and a pressure rod 36; each protective rod 33 is respectively connected to the two sliding sleeves 32 in a damping rotation manner; each protective rod 33 is penetrated by a clamping rod 35; each clamping rod 35 is respectively connected to the corresponding mounting plate 2 in a sliding manner; and each protective rod 33 is respectively welded with a plurality of pressure rods 36 at equal distances.

[0039] Furthermore, in order to facilitate pulling out the clamping rod 35 , a pull rod is provided on the upper portion of the clamping rod 35 .

[0040] In the second step of Example 1: In order to prevent the goods from tipping over and sliding off the slideway formed by the pedals 5 during the sliding process, protective rods 33 are arranged on both sides of the slideway, and the protective rods 33 are used to protect both sides of the goods to prevent the goods from tipping over; the height of the protective rods 33 can be adjusted to accommodate goods of different heights. When adjusting, the bolts 34 are removed from the mounting rod 31 and the sliding sleeve 32, and then the protective rod 33 and the sliding sleeve 32 are manually driven to move on the mounting rod 31. After moving to the specified position, the sliding sleeve 32 is fixed to the mounting rod 31 by the bolts 34.

[0041] If the trailer cargo board is higher, the inclination angle of the flat slideway formed by the pedals 5 will be higher. At this time, the speed at which the goods slide on the flat slideway formed by the pedals 5 will be faster. The high-speed sliding of the goods will cause the impact force to increase, which is easy to cause damage to the goods; therefore, in this case, the control cylinder three 21 drives the mounting plate two 22 and the sealing plate 23 to move upward intermittently. When the goods are above the sealing plate 23, the sealing plate 23 moves upward, which will lift the goods so that the goods are separated from the flat slideway and the sliding speed is slowed down; when the goods are between two adjacent sealing plates 23, the sealing plate 23 in front of the sliding direction of the goods will block the goods when it rises, and the speed of the goods sliding down will also be slowed down; when the speed of the goods sliding down is very fast, after the goods are blocked by the sealing plate 23, there is a problem of overturning out of control, resulting in damage to the goods. Therefore, the card rod 35 is pre-detached from the mounting plate 2 and the protective rod 33, and then the protective rod 33 and the pressure rod 36 are manually rotated so that the pressure rod 36 is located above the pedal 5. Figure 6-7As shown, the pressure rod 36 is used to limit the top of the cargo to prevent the cargo from turning over and losing control, resulting in damage. In addition, if the cargo is powdery material such as bagged fertilizer, the bagged fertilizer at the bottom of the trailer will be squeezed into agglomerates, and the agglomerated fertilizer may affect its dissolution rate and uniformity, thereby affecting the fertilizer effect. When farmers use it, they need to further break up the agglomerated waste, which increases the workload. When the cargo is located above the sealing plate 23, the sealing plate 23 moves upward, which will lift the cargo and contact it with the pressure rod 36. The sealing plate 23 and the pressure rod 36 cooperate to crush part of the agglomerated fertilizer, thereby reducing the labor of farmers to further break up the agglomerated waste when using the fertilizer.

[0042] Example 3

[0043] On the basis of Example 2, Figure 6-7 As shown, it also includes a rod sleeve 41 and bristles 42; each pressure rod 36 is rotatably connected to a rod sleeve 41; each rod sleeve 41 is fixedly connected to a plurality of bristles 42 arranged side by side.

[0044] Furthermore, it also includes a suction pipe 43; each mounting plate 1 2 is connected to a plurality of suction pipes 43.

[0045] In the second step of Example 1: some bagged goods have a lot of dust on their surface, such as bagged rice and flour, which will make the packaging look old and unclean, and may affect the appearance of the product. In addition, workers will absorb dust during subsequent handling, causing physical discomfort. Therefore, a rod sleeve 41 and bristles 42 are provided on the pressure rod 36. When the pressure rod 36 is located above the pedal 5, as shown in FIG. Figure 6-7 As shown, due to the gravity of the rod sleeve 41 and the bristles 42, the rod sleeve 41 and the bristles 42 will rotate on the pressure rod 36, so that the bristles 42 are vertically downward. When the bagged goods slide downward, the upper side of the bagged goods will pass through the bristles 42, and the bristles 42 will brush the dust on the upper side of the bagged goods. When the sealing plate 23 moves upward to lift the bagged goods, the dust on the lower side of the bagged goods will be shaken off. The suction pipe 43 is connected to the external suction equipment in advance. When the bagged goods slide, the external suction equipment is controlled to work, so that the suction pipe 43 generates suction to suck away the brushed and shaken dust. In this way, the dust on the surface of the bagged goods is removed to avoid affecting the appearance of the product and facilitate the subsequent handling by the workers.

The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
