Description

Technical Field

[0001] This utility model relates to the technical field of feed conveying trolleys, specifically to an anti-tipping feed conveying trolley. Background Technology

[0002] Feed conveyor technology is mainly used to accurately transport feed from the storage area to various breeding areas, reducing labor costs and improving work efficiency. Due to the complex pig farming environment, especially the layout of pig houses and uneven ground, feed conveyor carts need to be designed to prevent tipping over, which could lead to feed waste, equipment damage, or pigs not being able to receive feed in a timely manner, thus affecting their growth.

[0003] Chinese utility model patent CN220410659U discloses a transfer trolley with anti-tipping function, which includes "adjusting the position of the movable stop plate on the main body of the transfer trolley, and moving the threaded block and the movable stop plate by rotating the threaded rod, so that when the main body of the transfer trolley is transferring a television, the movable stop plate can move so that one side of the television at both ends abuts against the railing and the movable stop plate respectively, thereby stabilizing and limiting the movement of the television and further improving the stability of the transport." However, the above patent can only stabilize and limit the movement of the load by adjusting the position of the movable stop plate and cooperating with the railing to abut one side of the load of different sizes of the load, thereby preventing the load from falling over. However, during the loading and unloading of the load, the trolley body is easily affected by accidental impacts and collisions, causing the universal wheels at the bottom to slip, which can cause the trolley body to shake and tip over. This can lead to leakage and contamination of the load, pose safety risks, and reduce the user experience. Utility Model Content

[0004] The purpose of this invention is to provide an anti-tipping feed transport trolley to solve the problem mentioned in the background art that when the trolley body tipes over, it will cause leakage and pollution of the carried materials, and pose a safety risk.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-tipping feed conveying trolley, including a frame, a guardrail installed at one end of the top of the frame, and feed buckets provided at both ends of the top of the frame.

[0006] The bottom of the frame is fitted with a cover.

[0007] A groove is provided in the middle of the lower surface of the frame. A throttle is provided on one side of the groove. A double-ended screw is installed on one side of the throttle. The two ends of the double-ended screw are threaded to a connecting bracket. A pulley is installed at the bottom of the connecting bracket by screws.

[0008] The bottom of the inner wall of the base is equipped with uprights at both ends, and the top of the uprights is slidably connected to a pressure plate.

[0009] A return spring is fitted to the bottom of the upright, and ramps are installed at both ends of the top of the pressure plate.

[0010] The beneficial effects of this utility model are as follows: it avoids the risk of shaking or tipping due to accidental impact or collision during loading and unloading, ensures that the vehicle body is more stable when parked, avoids feed leakage and pollution caused by tipping, reduces safety hazards, improves user experience and operational safety, and makes feed delivery more reliable.

[0011] To achieve the vertical height adjustment of the pressure plate by adjusting the relative position of the two pulleys:

[0012] Further configuration: the bottom of the pulley abuts against the slope surface of the ramp block.

[0013] By adopting the above technical solution, when the two pulleys are adjusted in relative position, the bottom of the pulleys slides along the slope of the ramp block. When sliding towards both ends, they are hindered by the height of the slope, which in turn provides a relative counterforce to the ramp block, causing it to slide down along the surface of the frame. This allows the counterforce plate to be adjusted in vertical direction.

[0014] To enable the relative horizontal displacement adjustment of two pulleys synchronously by turning the throttle:

[0015] Further configuration: The connecting frame forms a transmission structure with the throttle via a bidirectional screw.

[0016] By adopting the above technical solution, rotating the throttle drives the bidirectional screw to rotate, and then using the screw to transmit power, the tops of the two connecting brackets slide relative to each other along the inside of the groove, which in turn drives the two pulleys at the bottom of the connecting brackets to adjust their relative displacement.

[0017] To ensure that the slope surface of the corresponding ramp block remains in contact with the bottom of the pulley during the reciprocating adjustment of the two pulleys:

[0018] Further configuration: The pressure plate forms a buffer structure with the upright frame through a reset spring.

[0019] By adopting the above technical solution, when the ramp block slides down along the surface of the frame, the return spring sleeved at the bottom of the frame will contract. When the bottom of the pulley slides away from the higher end of the ramp block's slope, the pressure on the ramp block will be released. At this time, under the influence of the elastic force, the ramp block will be pushed upward along the surface of the frame in the opposite direction, thereby raising the height of the ramp block to keep it in contact with the bottom of the pulley. This ensures that when not in use, the pressure plate will automatically raise its height and will not affect the normal movement and transportation of the trolley.

[0020] To improve the anti-slip positioning effect of the pressure plate when it decreases in height and presses against the ground:

[0021] Further features include: an anti-slip pad attached to the bottom of the pressure plate, and the anti-slip pad is made of rubber.

[0022] By adopting the above technical solution, a rubber anti-slip pad is attached to the bottom of the pressure plate. When the pressure plate is adjusted in height so that the anti-slip pad at the bottom presses against the ground, the raised or textured surface of the anti-slip pad increases friction and provides its elasticity and wear resistance to adapt to different ground conditions, thereby achieving a good anti-slip positioning effect.

[0023] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0029] Please see Figures 1 to 3 The anti-tipping feed conveying trolley includes a frame 1, a guardrail 2 installed at one end of the top of the frame 1, and feed buckets 3 at both ends of the top of the frame 1.

[0030] A bottom cover 4 is installed at the bottom of the frame 1.

[0031] A groove 5 is provided in the middle of the lower surface of the frame 1. A throttle 6 is provided on one side of the groove 5. A double-ended screw 7 is installed on one side of the throttle 6. The two ends of the double-ended screw 7 are threaded to a connecting bracket 8. A pulley 9 is installed at the bottom of the connecting bracket 8 by screws.

[0032] The bottom of the inner wall of the base cover 4 is equipped with two uprights 10, and the top of the uprights 10 is slidably connected to a pressure plate 11.

[0033] A return spring 12 is sleeved at the bottom of the upright 10, and ramp blocks 13 are installed at both ends of the top of the pressure plate 11.

[0034] In this embodiment, as Figure 3 As shown, the bottom of pulley 9 abuts against the slope surface of ramp block 13.

[0035] In this embodiment, as Figure 2 As shown, the connecting frame 8 forms a transmission structure with the throttle 6 via the bidirectional screw 7.

[0036] In this embodiment, as Figure 3 As shown, the pressure plate 11 forms a buffer structure with the upright frame 10 through the return spring 12.

[0037] In this embodiment, as Figure 3 As shown, the bottom of the pressure plate 11 is fitted with an anti-slip pad 14, and the anti-slip pad 14 is made of rubber.

[0038] The anti-tipping feed conveyor trolley operates as follows:

[0039] First, before loading or unloading the material bucket 3 placed on top of the frame 1, the operator needs to rotate the handle 6 to drive the double-ended screw 7 to rotate. This, in turn, uses the threaded transmission to drive the tops of the two connecting brackets 8 to slide relative to each other along the inside of the groove 5. Simultaneously, this drives the two pulleys 9 at the bottom of the connecting brackets 8 to adjust their relative displacement. At this time, the bottom of the pulleys 9 will slide along the slope of the ramp block 13. When sliding towards both ends, they will be hindered by the slope height, thus providing relative resistance to the ramp block 13. This causes the pressure plate 11 to slide downwards along the surface of the upright frame 10. At the same time, the return spring 12 contracts until the bottom of the pressure plate 11 is reached. The anti-slip mat 14 presses against the ground, providing additional support, anti-slip properties, and positioning for the trolley. This prevents the trolley from sliding or tipping due to accidental impacts or collisions, thus preventing feed leakage and contamination and improving safety. After loading and unloading, the reverse handle 6 drives the pulley 9 to slide towards the lower end of the ramp 13. Under the influence of elastic force, the pressure plate 11 is pushed upward along the surface of the stand 10, thereby raising the height of the ramp 13 and keeping it in contact with the bottom of the pulley 9. This cancels the pressure of the anti-slip mat 14 against the ground, preventing any impact on the trolley's subsequent normal use.
