Description

Technical Field

[0001] This invention relates to the design of automated silkworm rearing mechanisms and supporting silkworm rearing rooms, and in particular to a silkworm rearing machine. Background Technology

[0002] Because young silkworms are small, lightweight, and require less feed, the difference between traditional and mechanized farming methods is not as significant. However, in the rearing of older silkworms, the advantages of mechanized methods over traditional methods become very clear. Mechanized silkworm rearing is an important means to change the traditional manual silkworm rearing model and a crucial way to solve the bottleneck problems in the development of modern sericulture. With the development of modern sericulture, the demand for mechanized farming equipment is constantly increasing, and silkworm rearing machines have attracted much attention. For example, Shengzhou Mosang High-Tech Co., Ltd. has proposed a series of equipment for factory-style silkworm rearing operations, including matching rearing frames, automatic rearing frame transfer equipment, and rearing frame cleaning equipment. They have also proposed the idea of ​​setting up production lines according to age to form a full-age production line, which is worth learning from. However, their design is still based primarily on rearing frames similar to traditional silkworm trays.

[0003] The mainstream silkworm rearing method in current silkworm production is still multi-layer silkworm rearing, which has a stable structure, long silkworm platform length, large effective rearing area, and high space utilization. However, it is difficult to mechanize it. A similar example is the intelligent control single closed-loop fully automatic silkworm rearing machine for large silkworms disclosed in CN214178720U.

[0004] CN113994926A discloses an automated time-controlled cyclic silkworm feeding machine. Through the close cooperation of a feeding mechanism, a sorting conveyor, and a cyclic feeding mechanism, it can automatically feed silkworms on the silkworm rearing platform. Simultaneously, it can cyclically collect silkworm excrement and waste, achieving automated feeding of silkworms, saving labor costs, and improving feeding efficiency. This equipment uses an automated feeding mechanism to feed silkworms onto a fixed-position silkworm rearing net, but the mechanical equipment occupies a significant amount of space in the silkworm rearing channel.

[0005] Furthermore, CN114403104A discloses a track-type sliding feeding silkworm rearing room, including a rearing room body, multi-layer rearing racks, mulberry leaf trays, a scissor lift mechanism, and guide rails. The rearing room body has entrances at both the front and rear ends. The rearing area within the rearing room body has multiple rows of multi-layer rearing racks, with two guide rails between adjacent rows. Guide grooves are provided on the guide rails. The scissor lift mechanism is mounted on two guide rails, and its bottom has four moving wheels arranged in pairs. The two rows of moving wheels at the bottom of the scissor lift mechanism are correspondingly positioned within the guide grooves on the two guide rails. Mulberry leaf trays are mounted on a platform at the top of the scissor lift mechanism, allowing the trays to be placed on the rearing racks where workers operate, facilitating retrieval and appropriately reducing worker workload.

[0006] CN104106501A discloses an automatic silkworm feeding machine, which connects the track of the trolley lifting platform with a second track set on the silkworm platform, so that the trolley runs along the second track of the silkworm platform to realize automated feeding operations. Summary of the Invention

[0007] To facilitate silkworm rearing, this invention provides a translational silkworm rearing machine and silkworm house based on the integrated optimized design of silkworm rearing room, silkworm platform, and feeding equipment, under the concept of automated rearing machinery.

[0008] The technical solution adopted by this invention to solve its technical problem is: a translational silkworm rearing machine, including two silkworm rearing platforms arranged side by side on the left and right. Each of the two silkworm rearing platforms is equipped with silkworm rearing platform tracks with an even number of layers (4 or more) arranged vertically at intervals. Electric rollers are installed on the silkworm rearing platform tracks to translate and support the silkworm frames. The silkworm rearing platform tracks on the left and right silkworm rearing platforms are arranged at the same height. One silkworm rearing platform has silkworm frames arranged on the odd-numbered layers of the silkworm rearing platform tracks, while the other silkworm rearing platform has silkworm frames arranged on the even-numbered layers of the silkworm rearing platform tracks. It also includes a feeding cart that can travel between the two silkworm rearing platforms. The feeding cart is equipped with movable tracks. Feeding equipment is installed above the movable tracks. A lifting mechanism is connected below the movable tracks. The lifting mechanism drives the movable tracks to move vertically up and down and can position the movable tracks at the height of either layer of the silkworm rearing platform tracks to connect the silkworm rearing platform tracks on the left and right silkworm rearing platforms. In this way, each silkworm rearing frame can be moved from one side of the rearing platform along the platform track and the movable track to the other side of the same group. During the movement, the frames will pass under the rearing equipment via the movable track of the rearing cart. During this time, the rearing equipment can complete its corresponding operations. The rearing equipment can typically be a mulberry leaf dispensing device, a powdering and disinfection device, etc.

[0009] The electric roller, as the translational force for the silkworm rearing frame, does not create obstacles in the adjacent space above the frame compared to other translational drive methods such as winch drive. This facilitates feeding operations in the frame and is easily automated. It offers accurate positioning, adjustable speed, and the feeding equipment can utilize existing automated devices such as mulberry leaf spreaders or powder spreaders. By integrating their drive devices, such as the motor controller, with the electric roller's controller, the frame's running speed and start / stop functions can be adjusted to match the rhythm of the feeding equipment. This is not the focus of this invention and will be described further later.

[0010] Therefore, the translational silkworm rearing machine can achieve efficient automated operation. Although the electric roller needs to occupy a certain height space, the upper and lower silkworm frames of the multi-layer silkworm rearing platform already require a certain height difference. Therefore, the mechanical equipment occupies less silkworm rearing space. Compared with other existing automated breeding design schemes, it can still maintain the advantages of the multi-layer silkworm rearing platform in "fully utilizing the height of the silkworm house and increasing the effective breeding density of the silkworm house".

[0011] Preferably, the silkworm frame includes a bottom frame, the bottom surface of which serves as a friction surface for contacting the electric roller. The bottom frame is fixed to the bottom of the silkworm frame, thereby ensuring that the silkworm frame moves smoothly under the action of the electric roller and is not easily jammed.

[0012] Furthermore, horizontal and vertical rollers are installed on both sides of the bottom frame as guide wheels that match the silkworm rearing platform track and the moving track. The top surface of the electric roller is higher than the top surface of the vertical roller. The electric roller, as the power source for the silkworm rearing frame's translation, supports and drives the frame to move horizontally when in contact with it, allowing the frame to pass under the rearing equipment along the track and intermittently reciprocate between the left and right rearing platforms. The horizontal rollers primarily guide the frame's translation and reduce friction, while the vertical rollers primarily support the frame and reduce friction. The electric roller's start and stop can be coordinated with limit switches located at specific points on the track, ensuring accurate positioning of the frame even after multiple reciprocating motions between the two rearing platforms in the same group.

[0013] As mentioned above, this invention is an integrated optimized design based on silkworm rearing room, silkworm platform, and feeding equipment. This invention also provides a silkworm rearing room, which includes at least one passage, at least one end of which is the entrance and exit of the silkworm rearing room. Two rows of silkworm platforms are arranged on the left and right sides of the passage. Each of the two rows of silkworm platforms consists of two silkworm platforms arranged side by side as a group of silkworm platforms. Both silkworm platforms in the same group are provided with silkworm platform tracks with an even number of layers of four or more arranged vertically. Electric rollers are installed on the silkworm platform tracks to move or support the silkworm frames. The silkworm platform tracks of the left and right silkworm platforms are arranged at the same height. One silkworm platform arranges silkworm frames on the silkworm platform tracks with an odd number of layers, while the other silkworm platform arranges silkworm frames on the silkworm platform tracks with an even number of layers.

[0014] The odd-numbered and even-numbered layers mentioned above can both be counted from the bottom layer closest to the ground, or both can be counted from the top layer closest to the ceiling of the silkworm room.

[0015] Furthermore, the passageway is equipped with ground tracks for the feeding cart to travel on, and the feeding cart includes a track-type chassis that matches the ground tracks. A constant passageway width with fixed-length movable tracks, or a variable passageway width with retractable tracks that adjust to the passageway width, is more complex and not recommended. Typically, the silkworm rearing room floor is flat, and the passageway is straight, allowing the feeding cart to travel in a straight line, minimizing distance and maximizing efficiency. This also allows the feeding cart and equipment to operate under more stable conditions.

[0016] The silkworm rearing platforms in the same column all have silkworm frames arranged on the silkworm rearing platform tracks on the odd-numbered layers, while the silkworm rearing platforms in the corresponding other column all have silkworm frames arranged on the silkworm rearing platform tracks on the even-numbered layers.

[0017] The beneficial effects of this invention are: it realizes mechanized silkworm rearing on large-scale silkworm rearing platforms while improving the space utilization rate of silkworm rearing rooms. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the silkworm rearing room of the present invention includes at least one passageway 8, with both ends of the passageway 8 serving as entrances and exits for the silkworm rearing room 1. Two rows of silkworm rearing platforms are symmetrically arranged on the left and right sides of the passageway 8. Two silkworm rearing platforms arranged side-by-side on the left and right sides of the passageway 8 constitute a group of silkworm rearing platforms. The two silkworm rearing platforms in the same group are equipped with 2N layers of silkworm rearing platform tracks 6 arranged vertically at intervals, where N is a positive integer greater than or equal to 2. The silkworm rearing platform tracks 6 in the same group are arranged at equal heights. The silkworm frames 5 of one side of the silkworm rearing platform are arranged on the odd-numbered layers of the silkworm rearing platform tracks, while the silkworm frames 5 of the other side are arranged on the even-numbered layers of the silkworm rearing platform tracks. Electric rollers 7 are installed on the silkworm rearing platform tracks 6 to drive the silkworm frames 5 to move horizontally. The silkworm rearing platform tracks 6 and the movable tracks 9 each consist of two parallel single rails.

[0026] The width, height, and length of each silkworm rearing platform within the silkworm rearing room 1 are uniform. Typically, the platform width is 1-2 meters, the platform length is 5-30 meters, the number of silkworm frames is 3-6 layers, and the width of the passageway is 2-3 meters. The height of the silkworm frame layers is determined according to different rearing methods, and the number of silkworm rearing platforms is determined by the size of the silkworm rearing room. The passageway 8 has a ground track 3 for the feeding cart 4 to travel on. The feeding cart 4 includes a track-type chassis 44 that matches the ground track 3, facilitating the feeding cart 3 to move back and forth in a straight line.

[0027] like Figure 1 , Figure 2 As shown, the translational silkworm rearing machine of the present invention has an overall frame structure, which includes two silkworm rearing platforms 2 arranged side by side on the left and right. Figure 2 In this arrangement, two silkworm rearing platforms 2 are located inside the silkworm house 1, on the left and right sides of a passageway 8. The two platforms 2, side-by-side, form a group. Each platform 2 in the same group is equipped with 2N layers of silkworm rearing tracks spaced vertically at intervals, where N is a positive integer greater than or equal to 2. The tracks 6 on each layer of the same group are arranged at equal heights. The silkworm frames 5 on one side of the platform are arranged on the odd-numbered layers of tracks 6, while the silkworm frames 5 on the other side are arranged on the even-numbered layers. Electric rollers 7 are installed on the tracks 6 to drive the silkworm frames 5 to move horizontally. Typically, each layer of silkworm frames in a group is equipped with two electric rollers 7, one on each of the left and right platforms. The distance between the two electric rollers 7 is less than the length of the silkworm frame 5, and the electric rollers 7 are preferably arranged near the passage to ensure that the bottom of the silkworm frame is always in contact with at least one electric roller 7; it also includes a rearing cart 4, which is equipped with a lifting mechanism top plate 42, on which a movable track 9 is installed. The rearing equipment 41 is installed above the movable track 9, and a lifting mechanism 43 is connected below the lifting mechanism top plate 42. The lifting mechanism 43 can drive the movable track 9 to move vertically up and down, and can position the movable track 9 at the height of any silkworm rearing platform track 6 to connect the silkworm rearing platform tracks 6 on the left and right sides. The silkworm rearing platform tracks 6 on the left and right sides are arranged symmetrically with equal lengths, and the silkworm rearing platform tracks 6 are also part of the silkworm rearing machine frame structure.

[0028] The silkworm rearing machine can have up to N layers of silkworm frames 5 for raising silkworms. The silkworm frames 5 are placed on the silkworm platform track 6. On the left and right silkworm platforms, the silkworm frames 5 are arranged at intervals in the height direction, that is, the Mth layer of silkworm frames on the left and right sides are not on the same horizontal plane, where M is a positive integer from 1 to N.

[0029] like Figure 2As shown: N=8, that is, there are eight layers of silkworm rearing track 6 and four layers of silkworm frames 5. The distance between two adjacent layers of silkworm frames is approximately twice the distance between two adjacent layers of silkworm rearing track 6. Assuming that in the initial state, the silkworm frames 5 of the left silkworm rearing track in a certain group of silkworm rearing tracks are arranged on an odd-numbered layer, then the silkworm frames 5 of the right silkworm rearing track are arranged on an even-numbered layer. After a complete feeding operation is performed on this group of silkworm rearing tracks, that is, after all the silkworm frames 5 have passed completely under the feeding equipment 41 once, the silkworm frames 5 of the right silkworm rearing track are moved to the even-numbered layer of the left silkworm rearing track, while the silkworm frames 5 of the left silkworm rearing track are moved to the odd-numbered layer of the right silkworm rearing track.

[0030] A single translational silkworm rearing machine should include at least one set of silkworm rearing platforms, typically consisting of multiple sets of platforms arranged longitudinally along the passageway. To facilitate automatic control, the height difference between adjacent silkworm rearing platform tracks is usually the same. During operation, the silkworm frames of two silkworm rearing platforms in the same set move in opposite directions.

[0031] Each layer of the silkworm rearing track 6 is equipped with an electric roller 7. The electric roller 7 at the contact position with the bottom of the silkworm frame 5 is coated with rubber to increase friction and enhance the power of conveying the silkworm frame. The bottom of the silkworm frame 5 is a bottom frame 50, with a flat bottom surface without any protrusions or sharp points. This bottom surface serves as the main contact surface with the electric roller 7. On both sides of the bottom frame 50, horizontal and vertical guide wheels, namely horizontal rollers 51 and vertical rollers 52, are evenly installed. The horizontal rollers 51 contact the sides of the silkworm rearing track 6 and the movable track 9, while the vertical rollers 52 contact the top surfaces of the silkworm rearing track 6 and the movable track 9, supporting the silkworm frame 5 and ensuring that the silkworm frame 5 moves in a straight line when moving horizontally. The rollers convert the sliding friction between the silkworm frame 5 and the corresponding track into rolling friction, reducing the resistance to the horizontal linear movement of the silkworm frame. The silkworm frame 5 is usually oriented along its translational direction, has a relatively long length, and is allowed a certain degree of deflection in the length direction. The top of the electric roller should be slightly higher than the top of the vertical roller so that when the silkworm frame passes the electric roller, most of the weight of the silkworm frame is pressed onto the electric roller, increasing friction and ensuring sufficient power for conveying the silkworm frame.

[0032] like Figure 2 As shown, the length of the silkworm frame 5 is much greater than the length of the movable track 9. Therefore, the movable track 9 does not need to be equipped with an electric roller, but it can still ensure that the silkworm frame 5 has the corresponding translational force.

[0033] The electric roller integrates an electric motor, gear reducer, and sensor, and is rationally installed inside a steel pipe to create a self-powered roller. Therefore, when used in a conveying system, there's no need to consider motors, chains, intermediate shafts, or other auxiliary drive components, and the bulky gearbox is no longer required. Simply install the electric roller on a frame, connect the wires to a power source, and the work is complete. The electric roller used in this invention can employ existing technology, and is mainly selected based on the load weight and operating speed. In the application scenario of this invention, the electric roller will need to rotate in the opposite direction after each operation.

[0034] The operation process of this invention is as follows: The feeding cart 4 of the translational silkworm rearing machine moves to the silkworm rearing platform position to be operated via the ground track 3. The lifting mechanism 43 vertically delivers the feeding equipment 41 and the movable track 9 to its working layer, aligning the movable track 9 with the corresponding silkworm rearing platform track 6, so that the silkworm rearing platform tracks 6 on the left and right sides and the movable track 9 under the middle feeding equipment 41 form a passage. At this time, the lifting mechanism 43 remains stationary, and the electric roller 7 at the bottom of the silkworm frame 5 on the working layer starts, uniformly conveying the silkworm frame 5 from one side of the silkworm rearing platform, passing directly under the feeding equipment 41 to complete the feeding operation; when the silkworm frame 5 reaches the other side of the silkworm rearing platform, the electric roller 7 on the same layer on that side starts, until the silkworm frame 5 has completely moved to the other side of the silkworm rearing platform, the electric roller 7 stops, accurately stopping the silkworm frame 5 on that side of the silkworm rearing platform, waiting for the next operation. The above operation process is repeated to complete the feeding operation of each layer of silkworm frames on each silkworm rearing platform.

[0035] In this invention, the electric roller rotates at a constant speed, driving the silkworm frame to move horizontally and linearly at a constant speed. When the silkworm frame passes under the feeding equipment at a constant speed, the silkworm feeding operation is completed. Through the symmetrical arrangement of the silkworm platforms and the staggered distribution of the silkworm frames, the space of the silkworm house and the silkworm platforms is effectively utilized, thereby improving the space utilization rate of the silkworm house while realizing mechanized silkworm rearing on large silkworm platforms.

[0036] In this invention, the rearing cart can be modified from the silkworm disinfection machine with announcement number CN216319064U. A movable track is arranged on the upper platform of the lifting cart, and the disinfection device is installed above the movable track to realize the disinfection operation. Based on the aforementioned structure, the disinfection device is replaced with an electric feeder with announcement number CN209635315U to realize the mulberry leaf distribution operation. If necessary, the rearing cart can be improved with automatic control to realize the automatic linkage of corresponding actions such as starting and stopping the rearing equipment, moving the silkworm frame, and raising and lowering the lifting mechanism. Alternatively, the rearing equipment, silkworm frame, and lifting mechanism can be simply set up with independent start and stop controls for each, which are operated by the operator.

[0037] The core of this invention lies in breaking away from the conventional thinking of multi-layer silkworm rearing platforms. By laying silkworm rearing platform tracks, the arrangement of silkworm frames in conventional silkworm rearing platforms is changed from a layer-by-layer arrangement to a staggered arrangement. The movement of silkworm frames is combined with the movement and positioning of the rearing equipment along the channel, which can realize automated and efficient operation, and the control is simplified, and the structure is simple and easy to implement.
