[0027] The utility model will be explained below with specific embodiments, but is not limited to the utility model.

[0030] The adjusting frame 2 is rotationally installed on the conveyor 1, and the adjusting frame 2 and the conveyor 1 have overlapping parts, the adjusting frame 2 can swing around the connecting point, and the overlapping parts of the adjusting frame 2 and the conveyor 1 ensure the compactness of the structure and the stability of the connection. By rotating the adjusting angle, the material receiving equipment of different heights and positions is adapted, and the adaptability of conveying is improved; the design of the overlapping parts enhances the structural strength, reduces shaking and deviation, and ensures the stability of conveying.
[0031] The internal drive mechanism includes multiple driven shafts 201 rotatably mounted inside the adjusting frame 2. Driven belts 202 are externally connected to the driven shafts 201 and are connected to the drive shaft 102. When the drive shaft 102 rotates, it drives the driven belts 202 to move. The rotation of the drive shaft 102 transmits power to the driven shafts 201 inside the adjusting frame 2 via the driven belts 202. The multiple driven shafts 201 rotate in tandem, enabling the conveying of materials on the adjusting frame 2. The internal drive mechanism extends the power of the conveyor 1 to the adjusting frame 2, ensuring the continuity of material conveying during the oscillation of the adjusting frame 2. The arrangement of multiple driven shafts 201 and driven belts 202 can distribute the conveying force, improve conveying efficiency, and adapt to materials of different shapes and sizes.
[0032] A hand-cranked drive mechanism is installed between conveyor 1 and adjusting frame 2. The operator controls the swing angle of adjusting frame 2 by manually operating the hand-cranked drive mechanism. The hand-cranked drive method is simple and intuitive to operate, requires no complex electrical control or hydraulic system, is low in cost and easy to maintain; the operator can adjust it at any time according to actual needs, which is highly flexible.
[0033] A drive component is fixed to the outside of the conveyor 1. The output shaft of the drive component is connected to the drive shaft 102. When the drive component is working, the output shaft rotates, driving the drive shaft 102 to rotate, providing power for the entire conveying system.
[0034] Example 2
[0035] like Figures 1-6 As shown, based on Embodiment 1, this embodiment provides the structure of a hand-cranked drive mechanism, as detailed below:
[0036] The hand-cranked drive mechanism includes a first bracket 3 fixed to the conveyor 1 and a second bracket 4 fixed to the adjusting frame 2. A distance adjustment mechanism is connected between the first bracket 3 and the second bracket 4. The distance adjustment mechanism is driven by hand. The first bracket 3 is fixed to the conveyor 1, and the second bracket 4 is fixed to the adjusting frame 2. The distance adjustment mechanism connects the two. By manually driving the distance adjustment mechanism, the distance between the first bracket 3 and the second bracket 4 is changed, thereby realizing the swing of the adjusting frame 2 relative to the conveyor 1.
[0037] The distance adjustment mechanism includes a bushing 5 rotatably mounted on a first bracket 3. A lead screw 6 is rotatably mounted inside the bushing 5. A wear-resistant block 7 is threadedly connected to the end of the lead screw 6. The wear-resistant block 7 is rotatably mounted on a second bracket 4. The bushing 5 is rotatably mounted on the first bracket 3, and the lead screw 6 rotates inside the bushing 5. The end of the lead screw 6 is threadedly connected to the wear-resistant block 7, which is rotatably mounted on the second bracket 4. When the lead screw 6 is rotated, due to the threaded engagement, the wear-resistant block 7 moves axially along the lead screw 6, thereby changing the distance between the first bracket 3 and the second bracket 4.
[0038] The hand-operated part is fixed to one end of the lead screw 6 close to the shaft sleeve 5, and a nut is fixed to the other end of the lead screw 6 away from the hand-operated part, which serves as a limiting part to prevent the lead screw 6 from falling off the wear-resistant block 7. The hand-operated part is fixed to one end of the lead screw 6 close to the shaft sleeve 5, which facilitates manual rotation of the lead screw 6 by the operator. The nut is fixed to the other end of the lead screw 6 away from the hand-operated part, which prevents the lead screw 6 from falling off the wear-resistant block 7 and ensures the stability of the entire transmission structure.
[0039] The shaft sleeve 5 and the wear-resistant block 7 are both fixed with shafts, and the first support 3 and the second support 4 are both installed with fixed plates. The shaft sleeve 5 and the wear-resistant block 7 are rotatably installed on the corresponding fixed plates through the shafts, which enables the shaft sleeve 5 and the wear-resistant block 7 to stably rotate during the work process and ensures the smoothness of the transmission of the lead screw 6.
[0040] The number of driven belts 202 is multiple, and the multiple driven belts 202 form multiple sections of conveying positions, and there is an overlapping position between adjacent two sections of conveying positions. Under the driving of the driving shaft 102, the driven belts 202 work cooperatively to realize stable conveying of materials in different conveying positions.
[0041] The conveying belt 8 forms two sections of conveying positions, and each section of conveying position includes multiple driven belts 202. The driven belts 202 on the two sections of conveying positions are staggered, and the driven belts 202 close to the side of the conveyor 1 are sleeved on the conveying belt 8. When the driving shaft 102 rotates to drive the conveying belt 8 and the driven belts 202 to move synchronously, the materials are orderly conveyed in different conveying positions.
[0042] The conveying belt 8 inside the conveyor 1 extends to the inside of the adjusting frame 2 and is sleeved on the driven belts 202. The driving shaft 102 rotates to drive the conveying belt 8, and then drives the driven belts 202 in the adjusting frame 2 to rotate, realizing linkage of the entire conveying system.
[0043] The outer surface of the driven belt 202 is provided with wear-resistant patterns, which increases the friction between the driven belt 202 and the conveying belt 8 and other transmission components. In the transmission process, the materials can be better moved, and the wear of the driven belt 202 itself is reduced.
[0044] The driving part is fixed to the outside of the conveyor 1, the output shaft of the driving part is connected with the driving shaft 102, and when the driving part works, the output shaft rotates to drive the driving shaft 102 to rotate, providing power for the entire conveying system.
[0045] Embodiment Three

[0048] The conveying belt 8 forms two conveying positions, and the two conveying positions respectively include multiple driven belts 202, and the conveying belts 8 on the two conveying positions are staggered, wherein the driven belts 202 close to the side of the conveyor 1 are sleeved on the conveying belt 8, when the driving shaft 102 rotates to drive the conveying belt 8 and the driven belts 202 to move synchronously, the orderly conveying of the materials in different conveying positions is realized.
[0049] The conveying belt 8 inside the conveyor 1 extends to the inside of the adjusting frame 2 and is sleeved on the driven belts 202, the driving shaft 102 rotates to drive the conveying belt 8, and then drives the driven belts 202 in the adjusting frame 2 to rotate, realizing the linkage of the whole conveying system.
[0050] The outer surface of the driven belt 202 is provided with wear-resistant patterns, which increases the friction between the driven belt 202 and the conveying belt 8 and other transmission components, and in the transmission process, the materials can be better moved, and the wear of the driven belt 202 itself is reduced.
[0051] Working principle: after the driving component outside the conveyor 1 is started, the output shaft drives the driving shaft 102 to rotate, and the driving shaft 102 drives the conveying belt 8 to move through the driving belt 101. At the same time, the rotation of the driving shaft 102 transmits power to the multiple driven shafts 201 in the adjusting frame 2 through the driven belts 202, and the multiple driven shafts 201 rotate cooperatively, so that the materials can be conveyed on the adjusting frame 2.
[0052] The operator shakes the hand-operated component, and the lead screw 6 rotates, and since the lead screw 6 is threadedly connected with the wear-resistant block 7, the wear-resistant block 7 moves axially along the lead screw 6, and then the distance between the first support 3 fixed on the conveyor 1 and the second support 4 fixed on the adjusting frame 2 is changed, the swinging of the adjusting frame 2 relative to the conveyor 1 is realized, and the conveying angle of the materials is controlled.
