Description

Technical Field

[0001] This utility model belongs to the field of calf milk powder transportation technology, specifically relating to a calf milk powder transportation device. Background Technology

[0002] Currently, in livestock production, milk powder is widely used as an important substitute for breast milk to ensure the normal growth and development of calves. During the packaging, storage, and transportation of milk powder, especially when transporting unsealed milk powder bags from the mixing area to the usage area or temporary storage area, additional auxiliary operations such as manual lifting and neat stacking are often required to prevent leakage and ensure transportation stability. However, due to the relatively large size of the milk powder bags and their unsealed openings, tilting or sliding during transportation can easily lead to milk powder spillage, contamination, waste, or even damage to multiple bags.

[0003] In existing technologies, general-purpose conveying equipment is mostly used to transport milk powder bags, such as ordinary roller conveyor lines and belt conveyors. However, these structures generally lack dedicated limiting and fixing devices for unsealed milk powder bags, failing to effectively constrain the posture of the bags during movement. Furthermore, while some devices incorporate limiting blocks or edge designs, these are mostly fixed-height structures, unable to be flexibly adjusted according to the different sizes of the milk powder bags. This results in insufficient limiting effect for smaller bags and a risk of jamming for larger bags, severely impacting practical applicability and transportation efficiency.

[0004] In summary, existing milk powder bag transport devices still suffer from problems such as simple structure, poor limiting effect, and cumbersome adjustment operation in terms of adapting to different bag sizes, maintaining bag stability, and achieving synchronous transport control. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a calf milk powder transport device that can achieve synchronous adjustment, stable structure, reliable limiting, and strong adaptability, so as to meet the needs of efficient and safe transport of milk powder materials in modern animal husbandry.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a calf milk powder transport device, comprising a frame, a conveyor belt installed on the inner side of the frame, and extension plates extending outward on both sides of the upper surface of the frame, the conveyor belt being used to transport milk powder bags;

[0007] Synchronous motors are fixed on both sides of the bottom of the extension plate. A rotating shaft is installed at the output end of the synchronous motor. The rotating shaft extends beyond the upper surface of the extension plate. A pulley is slidably installed on the surface of the rotating shaft. A belt is sleeved on the surface of the two pulleys on the same side.

[0008] The two belts move synchronously with the conveyor belt. Multiple sets of fixing blocks are evenly installed on the outer surface of the belts. Limiting rods are provided on the surface of the fixing blocks. Two limiting rods in the same set limit the milk powder bag on both sides.

[0009] Furthermore, a keyway is provided on the surface of the rotating shaft along the axis, and a convex key is provided on the inner side of the pulley, the convex key sliding inside the keyway.

[0010] Furthermore, a stepped bushing is provided at the bottom of the pulley. The stepped bushing has a T-shaped cross-section that is smaller at the top and larger at the bottom, and the stepped bushing coincides with the axis of the pulley.

[0011] Furthermore, fixing bolts are vertically arranged on both sides of the upper surface of the extension plate, and two fixing bolts are respectively placed between the two rotating shafts. Positioning holes are evenly opened on the side surface of the two fixing bolts that are close to each other on the same side.

[0012] Furthermore, a lifting block is slidably mounted on the surface of the fixing bolt, and a U-shaped shift fork plate is fixed on one side of the lifting block. The U-shaped shift fork plate is installed on the upper half of the stepped bushing.

[0013] Furthermore, a connecting rod is provided between the two lifting blocks on the same side, and a limiting slide rod is symmetrically slidably installed on the inner side of the connecting rod. The end of the limiting slide rod is adapted to the internal size of the positioning hole, and a track groove is opened at the center of the upper surface of the connecting rod.

[0014] Furthermore, a lever is vertically provided at one end of each of the two limiting slide rods that are close to each other. Both levers pass through the track groove. A spring is placed in the center of the connecting rod. The spring is placed between the two limiting slide rods and applies an outward pushing force to each of the two limiting slide rods.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By setting belts that run synchronously on both sides of the conveyor belt and evenly installing multiple sets of fixing blocks and limiting rods on the outer surface of the belts, the milk powder bags can be stably limited on both sides during transportation, effectively preventing unsealed milk powder bags from tipping over due to slippage or tilting, and solving the problem of milk powder bags easily shaking and material leakage during transportation in the existing technology;

[0017] By setting a sliding fit between the pulley with a convex key structure and the rotating shaft with a keyway, the power transmission between the pulley and the synchronous motor is made more stable, avoiding the problem of limit control failure caused by slippage during the conveying process, and improving the reliability and control accuracy of the equipment.

[0018] By setting an adjustable lifting structure on both sides of the extension plate, and cooperating with components such as fixing bolts with multiple sets of positioning holes, limiting slide rods and springs, the height of the limiting rod can be flexibly adjusted according to the size of the milk powder bag, which solves the problem that the existing equipment has a fixed structure and is difficult to adapt to different sizes of milk powder bags, thereby improving the adaptability and efficiency of the equipment.

[0019] By coordinating the toggle lever structure with the limit slide and spring, the limit structure can be quickly released and automatically reset during operation, improving the convenience of height adjustment, reducing the intensity of manual operation, and solving the problems of cumbersome and inaccurate height adjustment in traditional devices.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] refer to Figures 1-5As shown, a calf milk powder transport device includes a frame 1, a conveyor belt 12 installed inside the frame 1, and extension plates 11 extending outward on both sides of the upper surface of the frame 1. The conveyor belt 12 is used to transport milk powder bags. The conveyor belt 12 is a continuous closed-loop structure and is driven by a transmission component installed below, thereby realizing the continuous movement of milk powder bags during transportation. To prevent milk powder bags from sliding or tipping over during transportation due to their unsealed state, the conveyor belt 12 is located in the middle of the frame 1 to maintain operational stability, and the conveying path is extended horizontally so that the limiting structure can synchronously control the state of the milk powder bags.

[0028] Synchronous motors 2 are fixed on both sides of the bottom of the extension plate 11. A rotating shaft 21 is installed at the output end of the synchronous motor 2. The rotating shaft 21 extends beyond the upper surface of the extension plate 11. A pulley 3 is slidably installed on the surface of the rotating shaft 21. A belt 4 is sleeved on the surface of the two pulleys 3 on the same side. The synchronous motor 2 is used to drive the two belts 4 to rotate and move at the same time. The rotational torque on the rotating shaft 21 is transmitted to the pulleys 3. The pulleys 3 drive the belts 4 to circulate. The belts 4 are respectively set on both sides of the conveyor belt 12 to ensure that they run at the same speed as the conveyor belt 12, so as to clamp and convey the milk powder bag without changing its original position.

[0029] Two belts 4 move synchronously with the conveyor belt 12. Multiple sets of fixing blocks 41 are evenly installed on the outer surface of the belts 4. Limiting rods 42 are set on the surface of the fixing blocks 41. Two limiting rods 42 in the same set limit the sides of the milk powder bag. The fixing blocks 41 are arranged at intervals on the outside of the belts 4. The spacing is controlled to achieve multi-point support for milk powder bags of different lengths. The limiting rods 42 are arranged vertically. Each set of limiting rods 42 and fixing blocks 41 form a closed clamping space. With the synchronous operation characteristics, the milk powder bag is restrained from tipping over. The number of limiting rods 42 can be flexibly arranged according to the distribution of milk powder bags, which effectively improves the reliability of transportation.

[0030] refer to Figure 2 and Figure 4 As shown, a keyway 22 is provided on the surface of the rotating shaft 21 along the axis, and a convex key 31 is provided on the inner side of the pulley 3. The convex key 31 slides inside the keyway 22. The sliding fit structure of the keyway 22 and the convex key 31 is used to realize the torque transmission between the rotating shaft 21 and the pulley 3, prevent the pulley 3 from slipping due to long-term operation, and allow the pulley 3 to be disassembled and adjusted when needed. The keyway 22 enables the pulley 3 to be accurately positioned during installation and improves the synchronous control accuracy.

[0031] refer to Figure 4As shown, a stepped bushing 32 is provided at the bottom of the pulley 3. The stepped bushing 32 has a T-shaped cross-section with a smaller top and a larger bottom. The stepped bushing 32 coincides with the axis of the pulley 3. The stepped bushing 32 serves as a transition component connecting the pulley 3 and the shift fork structure. The overall installation strength is achieved through structural interference fit, ensuring that the pulley 3 remains stable during adjustment. The T-shaped structure has a guiding and limiting function during the up and down sliding process, which helps to ensure the accuracy of the height control of the pulley 3.

[0032] refer to Figure 1 and Figure 2 As shown, two fixing bolts 13 are vertically arranged on both sides of the upper surface of the extension plate 11. The two fixing bolts 13 are respectively placed between the two rotating shafts 21. Positioning holes 131 are evenly opened on the side surface of the two fixing bolts 13 that are close to each other on the same side. The fixing bolts 13 are the guide support components of the lifting block 5. Their vertical arrangement helps to maintain the lifting stability. The positioning holes 131 are used to lock the lifting block 5 at different height positions, which is convenient to adapt to the transportation needs of milk powder bags of different heights. By setting the number and height distribution of the positioning holes 131, the height subdivision control can be realized, and the adaptability of the device can be improved.

[0033] refer to Figure 1 and Figure 4 As shown, a lifting block 5 is slidably mounted on the surface of the fixing bolt 13. A U-shaped shift fork plate 51 is fixed on one side of the lifting block 5. The U-shaped shift fork plate 51 is installed on the upper half of the step bushing 32. The up and down sliding of the lifting block 5 controls the height of the pulley 3. The shift fork plate 51 is connected to the step bushing 32 by a snap-fit ​​method and moves with the lifting block 5 as a whole to synchronously drive the pulley 3 to achieve height adjustment. The U-shaped shift fork plate 51 has its opening facing downward, which makes it easy to quickly insert into the step part of the step bushing 32 during adjustment to form a structural locking relationship, thereby preventing shaking and misalignment during the adjustment process.

[0034] refer to Figure 4 and Figure 5 As shown, a connecting rod 6 is provided between the two lifting blocks 5 on the same side. A limiting slide rod 7 is symmetrically slidably installed on the inner side of the connecting rod 6. The end of the limiting slide rod 7 is adapted to the internal size of the positioning hole 131. A track groove 61 is opened in the center of the upper surface of the connecting rod 6. The connecting rod 6 is used to synchronously control the lifting and lowering movement of the two lifting blocks 5. The track groove 61 provides a guide path for the lateral movement of the limiting slide rod 7, ensuring that the adjustment process is smooth and unobstructed. Under the action of the spring 8, the limiting slide rod 7 is usually in the state of engaging with the positioning hole 131. It can be quickly disengaged by manually controlling the lever 71 to complete the height adjustment operation.

[0035] refer to Figure 5As shown, two limit slide rods 7 are vertically mounted with a lever 71 at their ends that are close to each other. Both levers 71 pass through the track groove 61. A spring 8 is placed in the center of the connecting rod 6 and is positioned between the two limit slide rods 7. The spring 8 applies an outward pushing force to the two limit slide rods 7 respectively. The lever 71 serves as an operating component to release the limit state. By pressing the lever 71, the ends of the two limit slide rods 7 can be disengaged from the positioning hole 131, thereby releasing the lifting block 5 and realizing the free adjustment of the height of the pulley 3. The spring 8 provides an automatic reset function for the overall structure, ensuring that the limit slide rods 7 automatically return to the limit state after the lever 71 is released, further improving the convenience of operation and the accuracy of height adjustment.

[0036] The working principle of this utility model is as follows: When in use, the milk powder bag is evenly placed on the surface of the conveyor belt 12 for transportation. At the same time, the synchronous motor 2 is started to synchronously control the movement of the two belts 4 and ensure that the belts 4 and the conveyor belt 12 move synchronously. During the movement of the belts 4, multiple sets of fixing blocks 41 on their surface can be moved to limit the milk powder bag through two limit rods 42 in the same group to prevent it from tipping over during transportation. This invention can be applied to unsealed milk powder bags.

[0037] The height of the belt 4 can be flexibly adjusted according to the size of the milk powder bag. The spring 8 applies an outward pushing force to the two limiting slide rods 7 so that the ends of the limiting slide rods 7 cooperate with the positioning holes 131 of the corresponding height to keep the lifting block 5 fixed. Then, the height of the pulley 3 is kept fixed by the U-shaped fork plate 51. When adjusting, the two actuating rods 71 ​​are squeezed so that the limiting slide rods 7 are close to each other so that the ends of the limiting slide rods 7 are no longer in cooperation with the positioning holes 131. Then, the lifting and lowering of the connecting rod 6 is used to control the lifting of the two lifting blocks 5 at the same time, and then control the lifting of the pulley 3. When the height of the pulley 3 is adjusted, the cooperation between the convex key 31 and the keyway 22 can ensure the control of the pulley 3 by the synchronous motor 2. After the height adjustment is completed, the squeezing of the actuating rod 71 is released so that the lifting blocks 5 overlap and are limited, so as to adjust the height of the limiting rod 42, thereby adapting to the limiting work of milk powder bags of different heights and sizes, and further ensuring the limiting effect of the milk powder bag.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
