Description

Technical Field

[0001] This utility model relates to a mobile disinfection device for silkworm rearing. Background Technology

[0002] In silkworm rearing, disinfectant powder needs to be applied to the silkworm rearing beds and silkworms almost daily. Traditional manual powder application is labor-intensive, inefficient, and produces poor uniformity. Existing powder application equipment usually requires manual or close-range operation; for multi-layered silkworm rearing beds, each layer must be disinfected individually, which is inefficient; furthermore, close-range disinfection operations cause dust from the disinfectant powder, which is unbearable for workers.

[0003] The existing Chinese utility model patent, titled "Silkworm Disinfection Operation Machine" and published under the number CN216319064U, mentions an electric powder spreader disclosed in the Chinese utility model patent "Silkworm Feeding and Transmission Platform" published under the number CN209628422U. This device mechanizes the disinfection operation of silkworms raised on silkworm rearing platforms, improves the uniformity of disinfection, reduces labor intensity, and reduces dust from disinfection powder. Moreover, the device has a compact structure in its retracted state, making it convenient and flexible to move and turn. In particular, it is suitable for almost all types of silkworm rearing platforms used in current large-scale silkworm farming. However, this patent does not solve the problem of simultaneous disinfection of multiple layers.

[0004] The existing Chinese utility model patent, entitled "Cantilevered Labor-Saving Silkworm Rearing Platform" with publication number CN210519866U, discloses a multi-layered silkworm rearing platform that has been widely used in large-scale silkworm rearing. However, it does not address specific solutions for disinfecting each layer of the silkworm rearing platform, especially for disinfection operations on multi-layered silkworm rearing platforms. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a multi-layer cantilever powder spreader that can simultaneously perform powdering and disinfection operations on multiple layers of silkworm seats in a multi-layer silkworm rearing system.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a multi-layer cantilever powder-spreading machine, including a traveling trolley and a mounting frame fixed on the traveling trolley. The mounting frame is equipped with at least two layers of cantilever disinfection components. Each layer of cantilever disinfection components includes a pair of electric powder-spreading devices. The electric powder-spreading devices of each layer of cantilever disinfection components can be controlled to start or stop synchronously. Obviously, the spacing between each layer of cantilever disinfection components should be adapted to the spacing between adjacent upper and lower layers of silkworm rearing beds on the multi-layer silkworm rearing platform to be operated on. By synchronously starting and stopping the drive motors of the electric powder-spreading devices of each layer of cantilever disinfection components, the coordination between the powder-spreading equipment and the multi-layer silkworm rearing platform is achieved.

[0007] Furthermore, considering the low power required for powder spreading, the electric powder spreading device includes a screen tube, a brush structure, and a hopper. The screen tube includes at least a fixed section and a powder receiving section. The fixed section is fixed to the mounting frame, and the powder receiving section is connected to the discharge end of the hopper, with several screen holes. The brush structure includes a rotating shaft and brushes mounted on the shaft. The rotating shaft is located inside the screen tube and rotatably connected to it. The rotating shafts of all electric powder spreading devices are driven by the same powder spreading motor, thus simplifying control. Moreover, when arranging multi-layer silkworm rearing platforms in a silkworm house, coordination with automated machinery can be considered, allowing for the use of semi-multi-layer cantilevered silkworm rearing platforms in certain areas.

[0008] Furthermore, in each layer of the cantilevered disinfection assembly, the rotating shafts of the two electric powder-spreading devices are connected by a coupling, and each shaft is equipped with a first drive sprocket to drive its rotation. Adjacent cantilevered disinfection assemblies are connected to the first drive sprocket via chains. The bottom-level cantilevered disinfection assembly is equipped with a second drive sprocket, and the traveling trolley is equipped with a powder-spreading motor that is chain-driven to the second drive sprocket. That is, through the cooperation of chain drive and couplings, one powder-spreading motor drives all the electric powder-spreading devices on the traveling trolley.

[0009] Furthermore, the traveling trolley is a remote-controlled electric trolley that can move along a preset track. The trolley is equipped with a battery, a motor, and a control device electrically connected to the motor, and is also equipped with a remote control compatible with the control device. The battery powers both the motor and the powder-spreading motor, which are electrically connected to the control device. In this way, the traveling trolley is self-powered, avoiding complex power wiring, making it convenient for use in silkworm rearing rooms. Moreover, the movement of the trolley and the start / stop of the electric powder-spreading device can both be controlled by the same remote control.

[0010] The beneficial effects of this utility model are: by setting up multi-layer cantilever disinfection components on the mounting frame, and then rationally arranging the structure and drive mechanism of each layer of disinfection components, it is possible to disinfect the multi-layer silkworm seats of the multi-layer silkworm platform at the same time, which improves the work efficiency and safety, and can also improve the working environment.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example:

[0023] Please refer to Figure 1This embodiment provides a multi-layer cantilever powder spreader 100, which includes a traveling trolley 1 and a mounting frame 2 fixed to the traveling trolley 1. The traveling trolley 1 can be a non-powered trolley, pulled by human power or other traction devices during use. Alternatively, the traveling trolley 1 can be a self-powered trolley, such as an electric trolley. In this embodiment, the traveling trolley 1 is a remote-controlled electric trolley, which is existing technology. It comes with a battery 12, a trolley motor 13, a control device 14, and a remote controller 15, among other components. The battery 12 provides power to the entire trolley, the trolley motor 13 drives the wheels, and the remote controller 15 is matched with the control device 14, allowing the operator to remotely control the trolley. It should be noted that the remote-controlled electric trolley has wheels that can travel along a track 6, which can be a straight track, such as... Figure 7 As shown, it can also be a curved track, such as... Figure 8 As shown, the actual shape of track 6 is determined by the distribution of the multi-layered silkworm rearing platform.

[0024] Please refer to Figure 1 In this embodiment, the mounting frame 2 is fixed on the traveling trolley 1. The mounting frame 2 is made of industrial aluminum profile. According to the height and number of layers of the multi-layer silkworm rearing platform, at least two layers of cantilever disinfection components 3 are set on the mounting frame 2. The mounting frame 2, which is assembled from industrial aluminum profiles, allows for adjustment of the height between adjacent layers of cantilever disinfection components 3. Each layer of cantilever disinfection component 3 includes a pair of symmetrically distributed electric powder-sprinkling devices 31. This embodiment uses a multi-layer symmetrical structure of cantilever disinfection components 3. In each layer of cantilever disinfection component 3, the rotating shafts 312 of the two electric powder-sprinkling devices 31 are connected by a coupling 315, and the rotating shafts 312 are equipped with a drive. The first drive sprocket 41 of the rotating shaft 312 is connected to the cantilever disinfection components 3 of the two adjacent layers via a chain 316. The cantilever disinfection component 3 at the bottom layer is provided with a second drive sprocket 42. The traveling trolley 1 is provided with a powder-spreading motor 5 that is chain-driven with the second drive sprocket 42. In use, the traveling trolley 1 travels along the preset track 6 on the ground. When it reaches the powder-spreading operation position of the multi-layer silkworm rearing platform, the powder-spreading motor 5 starts, and the rotating shafts 312 of all electric powder-spreading devices 31 rotate at the same time. This enables the multi-layer rearing platform, i.e., the silkworm seat, to be disinfected at the same time, which improves the efficiency and safety of the operation.

[0025] Please refer to Figure 3-5In this embodiment, the electric powder spreading device 31 includes a screen tube 311, a brush 313 structure, and a hopper 314. The screen tube 311 includes at least a fixed section and a powder receiving section. The fixed section is fixed to the mounting frame 2 by a support base 317. The powder receiving section is connected to the discharge end of the hopper 314 and has a plurality of screen holes 3111. The brush 313 structure includes a rotating shaft 312 and a brush 313 disposed on the rotating shaft 312. The rotating shaft 312 is located inside the screen tube 311 and is rotatably connected to the screen tube 311 by a bearing with a self-sealing end cap. The brush 313 is a roller brush in the prior art. The brush 313 is mounted on the rotating shaft 312. When the rotating shaft 312 rotates, the brush 313 rolls the disinfectant powder in the hopper 314 into the lower part of the brush 313 and brushes the disinfectant powder down from the screen holes 3111 through the brush bristles, so as to achieve uniform spreading of disinfectant powder. In this embodiment, the sieve-tube powder spreading device uses a tube with sieve holes, resulting in a simple, compact, and rigid structure suitable for cantilever installation. It should be noted that the bearing with a self-sealing end cap used in this embodiment is a commercially available finished product.

[0026] It should be noted that, in this embodiment, the structure of the remote-controlled electric vehicle includes a frame 11, a front axle 16, a rear axle 17, and a front axle differential 18. The front axle 16 is located at the front of the remote-controlled electric vehicle, and the vehicle motor drives the front axle 16 through the front axle differential 18. The front wheels are mounted at both ends of the front axle 16. The rear axle 17 is located at the rear of the remote-controlled electric vehicle, and the rear wheels are mounted at both ends of the rear axle 17. The front axle 16 and the rear axle 17 are connected to the frame 11 via connectors 19. The mounting slot 111 is located at the upper front of the frame 11 and is used to mount the battery 12 and the control device 14. The mounting plate 112 is located at the upper rear and is used to mount the powder-spreading motor 5. The front sensor switch 131 and the rear sensor switch 132 are located at the front and rear ends of the frame 11, respectively. When the track is a curved track 6, such as Figure 8 The connector 19 of the remote-controlled electric car is replaced with the rotating connector in the prior art, so that the front axle 16, the rear axle 17 and the frame 11 of the car are rotatably connected, so that the car can move on the arc track 6.

[0027] It should be noted that each layer of cantilever disinfection component 3 can also be driven by a powder-spraying drive, such as a powder-spraying motor with lower power. That is, each layer of cantilever disinfection component 3 has two powder-spraying devices 31, and their rotating shafts 312 are still connected by a coupling 315. The rotating shafts 312 are equipped with powder-spraying drive components. The same purpose can be achieved by the control device 14 controlling the start and stop of each powder-spraying drive component at the same time. In this case, the rotating shafts of each layer of cantilever disinfection component 3 do not need to be connected by the aforementioned chain drive mechanism.

[0028] Please refer to Figure 9The battery provides power to the trolley motor 13 and the powder-spreading motor 5. The control device 14 and the remote controller 15 can transmit control signals to the control device 14. According to the control signals given by the remote controller 15, the control device 14 controls the first relay, the second relay, and the third relay. When the first relay is in the connected state, the trolley motor 13 rotates forward; when the first relay is in the disconnected state, the trolley motor 13 stops, stopping the trolley 1 from moving forward. When the second relay is in the connected state, the trolley motor 13 reverses, causing the trolley 1 to move backward; when the second relay is in the disconnected state, the trolley motor 13 stops, stopping the trolley 1 from moving backward. When the third relay is in the connected state, the powder-spreading motor 5 starts to perform the powder-spreading operation; when the third relay is in the disconnected state, the powder-spreading motor 5 stops, stopping the powder-spreading operation. In this way, remote control is possible, reducing labor intensity, avoiding dust from disinfectant powder, and improving the working environment. The induction switches include a front induction switch 131 and a rear induction switch 132. When either induction switch detects an object or pedestrian or other obstacle within the sensing distance, it sends a signal to the control device 14, and both the trolley motor 13 and the powder-spreading motor 5 stop, thus preventing collisions and improving safety.
