Description

Technical Field

[0001] This utility model relates to a winter insulation roller shutter adjustment device for livestock breeding sheds, belonging to the field of livestock breeding technology. Background Technology

[0002] In the livestock breeding industry, maintaining the temperature of the breeding shed in winter is a key link to ensure the healthy growth of livestock and poultry and improve breeding efficiency. To achieve winter insulation of the breeding shed, the common practice is to install heat-insulating roller shutters on the outside of the shed. The temperature inside the shed is controlled by adjusting the degree of opening and closing of the roller shutters. The opening and closing of the roller shutters usually depends on the adjustment device with steel wire as the transmission medium. That is, by winding and releasing the winding steel wires, the roller shutters are moved up and down or left and right along the shed to achieve the switching of the insulation state.

[0003] However, existing winter insulation roller shutter adjustment devices for livestock sheds have many technical defects in practical applications, making it difficult to meet the needs of efficient and stable insulation control: existing adjustment devices mostly use a single roller to wind the winding steel wire. Due to the lack of a reciprocating guide structure, the steel wire is prone to overlapping, knotting or deviating during the winding process, resulting in transmission jamming. In severe cases, it can even cause the steel wire to break and the roller shutter to jam. At the same time, the disordered winding of the steel wire will aggravate the wear of the roller and the steel wire, shorten the service life of the device, and increase the maintenance costs and downtime risks during the breeding process. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a winter insulation roller shutter adjustment device for livestock breeding sheds.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A winter insulation roller shutter adjustment device for livestock sheds includes two adjustment devices, several extension linkage components, and a drive component. The two adjustment devices are arranged in a parallel and symmetrical structure. The several extension linkage components are arranged between the two adjustment devices. The drive component is arranged on one side of one of the adjustment devices. The adjustment devices are used to reciprocate and wind the winding steel wire to prevent tangling.

[0006] The above technical solution uses two parallel and symmetrical adjustment devices as the core, and several extended linkage components are connected between the two adjustment devices to achieve synchronous power transmission. The drive component is installed on one side of one of the adjustment devices and provides power. The adjustment device uses a specific structure to reciprocate the winding steel wire to avoid the steel wire from overlapping or knotting during the winding process.

[0007] Symmetrical adjustment devices ensure balanced force on the roller shutter, prevent it from tilting, improve insulation, and prevent the winding wire from getting tangled, thus reducing equipment jamming and wear, extending the service life of the device, and lowering the maintenance frequency.

[0008] Preferably, the adjusting device includes an insulation shell, a maintenance plate is detachably connected to one side of the insulation shell, through holes are provided on both sides of the insulation shell, and a reciprocating winding mechanism is provided inside the insulation shell.

[0009] Through the above technical solution, the insulation shell of the regulating device provides protection and insulation environment for the internal components, and the detachable inspection plate makes it easy to open the shell to inspect and replace the internal parts; the through holes on both sides of the insulation shell are used for the transmission rod to pass through, and the internal reciprocating winding mechanism directly realizes the reciprocating winding function of the steel wire.

[0010] The insulated shell protects the internal mechanism from the effects of low winter temperatures, rain, snow, and dust, ensuring stable operation of the mechanism in low-temperature environments. The removable inspection panel reduces maintenance difficulty, allowing for maintenance without disassembling the entire device, saving maintenance time and costs.

[0011] Preferably, the reciprocating winding mechanism includes a mounting plate disposed on the inner bottom of the insulation shell. A transmission rod is disposed on one side of the mounting plate, one end of which is placed in a through hole. A worm gear is disposed on the outer side of the transmission rod, and a worm wheel is meshed with the outer side of the worm gear. One side of the worm wheel is rotatably connected to one side of the mounting plate, and a cam is disposed on one side of the worm wheel. A rotating shaft is disposed on one side of the mounting plate, and a reciprocating frame is sleeved on one side of the rotating shaft. One side of the reciprocating frame abuts against one side of the cam. An elastic guide component is disposed on the other side of the reciprocating frame. Two limiting discs are sleeved on the outer side of the transmission rod, and a wire winding area is disposed between the two limiting discs.

[0012] Through the above technical solution, the mounting plate is fixed to the bottom of the inner side of the insulation shell, providing installation support for components such as the transmission rod and worm gear; one end of the transmission rod passes through the through hole, and the worm gear on its outer side rotates with the transmission rod and meshes with it to drive the worm gear to rotate; the cam on one side of the worm gear rotates synchronously, the cam abuts against the reciprocating frame and pushes it to swing around the axis, and the elastic guide component assists the reciprocating frame to reset; the two limiting discs on the outer side of the transmission rod form a wire winding area, limiting the wire winding range.

[0013] The meshing transmission of the worm gear and worm wheel enables power steering and deceleration, ensuring stable cam speed, which in turn makes the reciprocating frame swing rhythm uniform and the wire winding more regular. The limit plate prevents the wire from exceeding the preset winding range, and the elastic guide component ensures continuous movement of the reciprocating frame, further preventing wire tangling and improving the smoothness of the roller shutter's opening and closing.

[0014] Preferably, the elastic guide assembly includes a spring and a guide member, the guide member being disposed on one side of the mounting plate, one end of the spring being connected to one side of the guide member, and the other end of the spring being connected to one side of the reciprocating frame.

[0015] With the above technical solution, the guide is fixed on one side of the mounting plate, and one end of the spring is connected to the guide and the other end is connected to the reciprocating frame. When the cam rotates and pushes the reciprocating frame to swing to one side, the spring is stretched or compressed. When the cam rotates to the non-contact position, the spring drives the reciprocating frame to reset through the elastic force, so as to realize the reciprocating motion.

[0016] The spring's elastic force automatically drives the reciprocating frame to reset, requiring no additional power, simplifying the structure and reducing energy consumption. The elastic guide assembly ensures the stability and continuity of the reciprocating frame's movement, preventing uneven wire winding caused by movement interruptions.

[0017] Preferably, the lower side of the heat-insulating shell is provided with a wire hole.

[0018] Through the above technical solution, the wire hole on the lower side of the insulation shell provides an entry and exit channel for the winding wire. After the wire passes through the wire hole, it connects to the roller shutter. When winding, the wire enters the winding area inside the shell along the wire hole. When unwinding, it passes through the wire hole and drives the roller shutter to unfold.

[0019] The wire holes limit the movement path of the steel wire, preventing it from deviating during winding and ensuring stable operation of the roller shutter. The wire holes also reduce the amount of external dust and impurities entering the housing along with the steel wire, protecting the reciprocating winding mechanism and reducing wear on components.

[0020] Preferably, the extended linkage assembly includes a rod body, an A-shaped cross-shaped plug block, and an A-shaped cross-shaped plug slot. The A-shaped cross-shaped plug block and the A-shaped cross-shaped plug slot are respectively disposed on both sides of the rod body, and one end of the transmission rod is provided with a B-shaped cross-shaped plug slot that matches the A-shaped cross-shaped plug block.

[0021] Through the above technical solution, the rod of the extension linkage component is the main body, and A cross-shaped plug block and A cross-shaped plug slot are respectively set on both sides; one end of the transmission rod of the adjustment device is provided with B cross-shaped plug slot, and A cross-shaped plug block can be inserted into B cross-shaped plug slot to realize the connection between the rod and the transmission rod. Then, through the splicing of multiple extension linkage components, different adjustment devices are connected and power is transmitted.

[0022] The cross-joint structure ensures a secure connection and high transmission efficiency, preventing slippage during power transmission and guaranteeing synchronized operation of multiple adjustment devices. The number of extension linkage components can be increased or decreased according to the length of the livestock shed, making it highly adaptable and suitable for sheds of different sizes.

[0023] Preferably, the drive assembly includes a drive motor and a B cross-shaped connector block, wherein the B cross-shaped connector block is disposed at the output end of the drive motor and matches the A cross-shaped connector slot.

[0024] With the above technical solution, the drive motor of the drive component is the power source, and its output end is equipped with a B cross-shaped plug block; the B cross-shaped plug block can be inserted into the A cross-shaped plug slot of the extension linkage component. After the drive motor starts, it drives the rod of the extension linkage component to rotate through the B cross-shaped plug block, thereby transmitting the power to the transmission rod of the adjustment device.

[0025] The cross-type connector facilitates the assembly and disassembly of the drive assembly and extension linkage assembly. In case of drive motor failure, it can be quickly disassembled and replaced, reducing downtime for maintenance. The drive motor provides stable power, avoiding the tedious manual adjustments, improving the efficiency of the roller shutter's operation, and adapting to the frequent insulation adjustments required in winter.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a symmetrically arranged adjustment device that ensures balanced force on the roller shutter, prevents it from tilting, improves insulation, and prevents the winding steel wire from getting tangled, thus reducing equipment jamming and wear, extending the device's service life, and lowering maintenance frequency.

[0027] In this invention, the meshing transmission of the worm gear and worm wheel enables power steering and deceleration, ensuring stable cam speed, which in turn makes the reciprocating frame swing rhythm uniform, the steel wire winding more regular, the limit plate prevents the steel wire from exceeding the preset winding range, and the elastic guide component ensures continuous movement of the reciprocating frame, further preventing steel wire from tangling and improving the smoothness of the roller shutter's opening and closing.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-3 This utility model provides a technical solution: A winter insulation roller shutter adjustment device for livestock sheds includes two adjustment devices 1, several extension linkage components 2, and a drive component 3. The two adjustment devices 1 are arranged in a parallel and symmetrical structure at corresponding positions in the shed. The several extension linkage components 2 are sequentially connected and arranged between the two adjustment devices 1 for transmitting power and connection. The drive component 3 is located on one side of one of the adjustment devices 1, serving as the power source for the entire device.

[0033] The adjusting device 1 is used to reciprocate the winding of the steel wires in the insulated roller shutter. Its core function is to prevent the steel wires from concentrating in a single position on the drum during winding, thus achieving uniform and neat winding and avoiding tangled wires or jamming. The adjusting device 1 includes an insulated shell 11, which is typically made of heat-insulating material to reduce heat exchange between the inside and outside of the shed through the device itself, improving the insulation effect in winter. A maintenance plate 12 is detachably connected to one side of the insulated shell 11 via bolts or other fasteners, facilitating subsequent maintenance and repair of the internal mechanism. Through holes 13 are provided on both side walls of the insulated shell 11 to accommodate the end of the transmission rod 15 and allow it to rotate.

[0034] The insulation shell 11 is internally equipped with a reciprocating winding mechanism. Specifically, the reciprocating winding mechanism includes a mounting plate 14 fixedly installed on the bottom inner side of the insulation shell 11. The transmission rod 15 is supported by rotating components such as bearings, with one end passing through a through hole 13 on one side and exposed to the outside of the insulation shell 11, and the other end passing through or supported on a through hole 13 on the other side. A worm gear 17 is fixedly sleeved on the end of the transmission rod 15 located inside the insulation shell 11.

[0035] A worm gear 18 meshes with the worm 17 and is rotatably connected to one side of the mounting plate 14 via a short shaft. A cam 19 is fixedly mounted on one side of the worm gear 18. A rotating shaft 110 parallel to the transmission rod 15 is also fixedly mounted on the mounting plate 14. A reciprocating frame 111 is slidably sleeved on the rotating shaft 110 and can reciprocate linearly along the axial direction of the rotating shaft 110. One end of the reciprocating frame 111 is provided with a roller or a smooth contact block so that one side of it can always abut against the contour surface of the cam 19.

[0036] The other end of the reciprocating frame 111 is connected to an elastic guide assembly. The elastic guide assembly includes a spring 112 and a guide member 113. The guide member 113 can be a guide rod or a guide sleeve fixed to the mounting plate 14. The spring 112 is sleeved on the outside of the guide member 113, with one end abutting against the base of the guide member 113 or the mounting plate 14, and the other end connected to the reciprocating frame 111. Under the elastic force of the spring 112, the reciprocating frame 111 has a tendency to always move in the direction of the cam 19, thereby ensuring its continuous contact with the cam 19.

[0037] On the transmission rod 15, located on both sides of the worm gear 17, two limiting discs 114 are fixedly sleeved. These two limiting discs 114 are spaced a certain distance apart on the transmission rod 15, thus forming a wire winding area in the section of the transmission rod 15 between the two limiting discs 114. The end of the wire used for winding and unwinding the thermal insulation roller shutter is fixed in this area and winds as the transmission rod 15 rotates. A wire hole 115 is provided on the lower side of the thermal insulation shell 11, through which the wire is led out and connected to the thermal insulation roller shutter.

[0038] The extension linkage assembly 2 is used to connect and transmit power to the power adjustment device 1. It includes a rod 21, with an A-shaped cross-shaped insertion block 22 and an A-shaped cross-shaped insertion slot 23 fixedly disposed at both ends. At the exposed end of the transmission rod 15 of one of the adjustment devices 1, a B-shaped cross-shaped insertion slot 16 matching the A-shaped cross-shaped insertion block 22 is provided. By inserting the A-shaped cross-shaped insertion block 22 into the B-shaped cross-shaped insertion slot 16, the extension linkage assembly 2 and the adjustment device 1 can be quickly connected and power transmitted. Multiple extension linkage assemblies 2 are connected in series through the sequential insertion of the A-shaped cross-shaped insertion blocks 22 and A-shaped cross-shaped insertion slots 23, thereby transmitting power from the driving end to the driven end of the adjustment device 1.

[0039] The drive assembly 3 includes a drive motor 31 and a B-shaped cross-shaped connector 32. The drive motor 31 is fixedly mounted by a bracket. The B-shaped cross-shaped connector 32 is fixedly mounted on the output shaft of the drive motor 31. The B-shaped cross-shaped connector 32 matches the A-shaped cross-shaped connector slot 23 at the end of the extension linkage assembly 2. By inserting the B-shaped cross-shaped connector 32 into the A-shaped cross-shaped connector slot 23 of the first extension linkage assembly 2, the power connection between the drive motor 31 and the adjustment device link can be realized.

[0040] The workflow of this embodiment is as follows: When it is necessary to raise or lower the heat-insulating roller shutter, the drive motor 31 is started. The drive motor 31 drives the extension linkage component 2 connected to it to rotate through the B cross-shaped plug block 32. The power is transmitted to the transmission rods 15 of the two adjustment devices 1 through the series-connected extension linkage component 2, so that the two transmission rods 15 rotate synchronously in the same direction.

[0041] When the transmission rod 15 rotates, it drives the steel wire on it to wind up or unwind, thereby raising or lowering the heat-insulating roller shutter.

[0042] Simultaneously, the rotation of the transmission rod 15 drives the worm gear 17 to rotate, which in turn drives the worm wheel 18 meshing with it to rotate. The worm wheel 18 drives the cam 19 on its end face to rotate as well. Since the profile of the cam 19 is non-circular, when it rotates, it pushes the reciprocating frame 111, which is in contact with it, to overcome the elastic force of the spring 112 and move away from the cam 19 along the shaft 110. After the protruding part of the cam 19 has rotated past, the reciprocating frame 111 is pushed back by the restoring force of the spring 112. The continuous rotation of the cam 19 causes the reciprocating frame 111 to perform continuous reciprocating linear motion on the shaft 110.

[0043] Since the reciprocating frame 111 is sleeved on the outside of the transmission rod 15 used for winding the steel wire, the reciprocating motion of the reciprocating frame 111 will eventually guide the steel wire being wound, so that it is evenly distributed back and forth in the steel wire winding area between the two limiting discs 114, thereby achieving the purpose of preventing the steel wire from being concentrated and avoiding tangled wire.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
