Description

Technical Field

[0001] The present invention relates to the technical field of silkworm rearing waste cleaning equipment, and particularly relates to a silkworm rearing waste cleaning device for silkworm rearing. Background Art

[0002] After silkworms are fed with mulberry leaves, there will be some remaining mulberry leaf residues and silkworm feces, namely the so-called silkworm excrement. In daily silkworm rearing, it is necessary to remove the silkworms from the rearing tray and then pack and clean these wastes on the bottom cloth of the tray. Usually, they are rolled up and directly poured into a fixed container for centralized treatment to achieve the purpose of cleaning the wastes. In fact, among the silkworm rearing wastes, silkworm excrement is a very good medicinal material with great medicinal value. Therefore, when cleaning the silkworm rearing wastes, it is necessary to separately clean the silkworm excrement. The traditional fine method usually involves multiple fine sieving. And in the process of cleaning, a primary step that must be involved is to initially remove the mulberry leaf residues in the wastes. Currently, the operation is mostly to directly spread the wastes manually on the ground, similar to raking the straw and leaf residues from grains, and manually rake them out one by one, and then carry out the next fine cleaning process. This is inefficient for large-scale silkworm rearing enterprises in the initial cleaning. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a silkworm rearing waste cleaning device for silkworm rearing to solve the problem in the prior art that the floating residues such as mulberry leaf residues in the silkworm rearing wastes cannot be automatically initially cleaned.

[0004] The present invention is realized through the following technical solutions: A silkworm rearing waste cleaning device for silkworm rearing includes a vibrating screen and a conveyor belt. The conveyor belt is an inclined flat plate, and guardrail plates are arranged oppositely on both sides to form a transport trough. The vibrating screen is also inclined, and its discharge end is the lower end and is connected to a conveying plate. The vibrating screen can reciprocate along the width direction of the flat plate to let the silkworm excrement in the wastes fall through. And the discharge end of the vibrating screen is connected to the high-position end of the flat plate to input the screened wastes onto the flat plate and continue to convey them downward. On the inner wall of one of the guardrail plates at the lower end of the flat plate, a column is tightly fixed. On the guardrail plate that the column abuts against on the side towards the higher end of the flat plate, there is a slag discharge port, and an automatically opening and closing slag discharge door is installed at the slag discharge port. One end of a rake claw assembly is hinged to the column. The rake claw assembly spans above the flat plate to rake out some mulberry leaf residues in the wastes flowing through its lower part. And the rake claw assembly rotates around the column against the waste conveying direction, and then pushes the raked mulberry leaf residues to the slag discharge port for discharging.

[0005] Specifically, the height of the slag discharge port must satisfy that when the rake claw assembly rotates to abut against the guardrail plate, the bottom edge of the rake claw assembly is flush with the bottom edge of the slag discharge port.

[0006] Furthermore, the rake claw assembly includes a transverse plate and a plurality of rake teeth fixed to the bottom surface of the transverse plate and arranged at intervals along the length direction of the transverse plate.

[0007] Furthermore, a gear shaft parallel to the width direction of the flat plate is fixed to the upper part of one end of the horizontal plate, and the gear shaft is rotatably installed at the bottom of an articulated frame. A first bevel gear is fixed to the end of the gear shaft, and the first bevel gear is meshed with a second bevel gear fixed on the side wall of the column, and the axis of the second bevel gear is vertically arranged; one end of the articulated frame is hingedly installed in the side wall of the column, and the lower part of the other end is hinged to the top of the horizontal plate through a movable hinge.

[0008] Furthermore, the hinged frame includes a shaft sleeve and a cross arm fixed to the shaft sleeve, the shaft sleeve is rotatably sleeved with a hinge column vertically fixedly installed in the column, the cross arm is arranged parallel to the cross plate, the cross arm is respectively fixed to one of the leaves of the loose leaf and a hinge sleeve through two connecting rods, and the other leaf of the loose leaf is fixed to the cross plate;

[0009] The articulated sleeve is a tubular structure with a strip opening on one side, the strip opening runs through both ends of the articulated sleeve, the gear shaft is rotatably installed in the articulated sleeve, and the top surface of the cross plate extends into the strip opening and is fixed to the gear shaft as a whole, and the cross plate is located in the radial direction of the gear shaft.

[0010] Furthermore, the cross plate includes an outer plate and an inner plate, the inner plate is slidably mounted in the mounting cavity at the bottom end of the outer plate, and the inner plate is hingedly connected to the outer plate by one end of the second bevel gear, a driven gear is fixed on the hinge shaft of the two, and the driven gear is meshed with a driving gear driven by a micro motor fixed on the outer plate; the hinge column is transmission-connected to the main shaft of a power motor mounted on the column, and the power motor and the micro motor are linked and controlled, and the specific linkage method is: when the rake claw assembly rotates toward the slag discharge port, the inner plate rotates counterclockwise, so that when the rake claw assembly approaches the guardrail plate, the bottom end of the rake teeth is not lower than the lower edge of the slag discharge port.

[0011] Furthermore, the rake teeth are rod-shaped structures, and the bottom ends of the rake teeth are spherical.

[0012] Furthermore, there is a pad block near the slag discharge port, which is fixed on the column, and the flat plate is partially raised to cover the pad block and extend downward, so that the raised part is positioned by the pad block and serves as a raised portion, and the top surface of the raised portion shall not exceed the lower edge of the slag discharge port.

[0013] Furthermore, the side surfaces of the upright posts are fixedly fitted with the guardrail plates, the two side surfaces of the flat plate are in sliding contact with the two guardrail plates, and the bottom end of the upright posts is in sliding contact with the flat plate.

[0014] Further, the slag discharge port is connected to a screening and filtering device through a slide to screen out the silkworm excrement mixed in the waste.

[0015] The beneficial effects of the present invention are as follows:

[0016] For the silkworm breeding waste cleaning device for silkworm breeding, after filtering out the mixture of mulberry leaf residues and silkworm excrement through a vibrating screen, it is conveyed downward by rolling on an inclined flat plate. During the rolling process, since the silkworm excrement has a greater density and is granular, the silkworm excrement gradually lies in the lower layer, while the residues are in the upper layer. After the rake claw assembly intercepts the floating slag in the upper layer, it rotates counterclockwise and automatically adapts to the slope change of the inclined flat plate, pushing the mulberry leaf residues to the slag discharge port, and then discharging them into the next screening device for fine cleaning and separation. The whole process is simple and has high efficiency. Without large-area artificial spreading, the preliminary cleaning of residues such as mulberry leaves can be completed.

[0017] Other advantages, objectives, and features of the present invention will be described to some extent in the subsequent specification, and to some extent, they will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be achieved and obtained through the following specification. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Components of the embodiments of the present invention described and illustrated in the accompanying drawings here can be arranged and designed in a variety of different configurations.

[0025] Therefore, the detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0026] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0027] Please refer to Figure 1-2 , the present invention provides a technical solution: a device for cleaning silkworm-raising waste for silkworm raising. In terms of its structure, it mainly includes a vibrating screen 1 and a conveyor belt. Specifically, the conveyor belt in this embodiment is an inclined flat plate 18, that is, it does not need to be provided with a power transmission system like a conventional conveyor belt, and guard plates 2 are arranged oppositely on both sides of the flat plate 18 to form a transport trough with a rectangular cross-section. In this embodiment, as Figure 5As shown, the vibrating screen 1 is also inclined, with its discharge end being the lower end and connected to a conveying plate 20. The reason for the inclination is mainly to facilitate the movement of the waste residue towards the discharge end of the vibrating screen 1 during the screening process. At the same time, the vibrating screen 1 can reciprocate along the width direction of the flat plate 18, which is also one of the reasons why the conveyor belt in this embodiment does not use power drive. Otherwise, there will be a situation of waste accumulation and transportation in a long and snake-shaped path. The vibrating screen 1 can be a conventional horizontally vibrating screen 1, and its main purpose is to screen out the silkworm excrement in the waste. For the waste of sericulture, it is mainly the residual mulberry leaf residue after being eaten, as well as silkworm excrement. Among them, the silkworm excrement is basically in the form of regularly shaped and sized particles. Therefore, the primary screening of the vibrating screen 1 can well separate most of the silkworm excrement. In addition, the discharge end of the vibrating screen 1 in this embodiment is connected to the high-position end of the flat plate 18, that is, connected to the top port of the flat plate 18. That is, the aforementioned conveying plate 20 can be located on the surface of the top port of the flat plate 18 to smoothly input the screened waste onto the flat plate 18. The waste can roll down or fall freely, or when it accumulates to a certain extent, it can roll down in a free-collapse manner. Moreover, since the vibrating screen 1 vibrates horizontally and reciprocates along the width direction of the flat plate 18, the residual fertilizer thrown out by vibration will be more evenly distributed along the width direction of the flat plate 18, rather than being piled up like in traditional dumping, which requires leveling or additional power transmission. This enables the flat plate 18 in this embodiment to not require power to disperse and transport the screened waste. On the other hand, a column 3 is fixedly attached to the inner wall of one of the guardrail plates 2 near the low-position end of the flat plate 18. A slag discharge port is provided on the guardrail plate 2 that the column 3 abuts against on the side towards the higher end of the flat plate 18. An automatically opening and closing slag discharge door is installed at the slag discharge port for discharging slag. In practice, the slag discharge port is connected to a screening and filtering device through a slide (not shown in the figure) to screen out the silkworm excrement mixed in the waste. This is mainly designed according to the screening requirements. In the cleaning scenario with a large quantity and a high extraction rate of silkworm excrement, it is necessary to additionally set up this screening and filtering device to further separate the remaining silkworm excrement. Specifically, one end of a rake claw assembly is hinged to the column 3. The rake claw assembly spans above the flat plate 18 to rake out some of the mulberry leaf debris in the waste flowing below it. Moreover, the rake claw assembly rotates around the column 3 against the waste conveying direction, according to Figure 1In the shown orientation, the rake claw assembly rotates counterclockwise upward by 90 degrees, and then pushes the shredded mulberry residues raked to the slag discharge port for discharging. To avoid material leakage, the opening of the slag discharge port can be linked with the counterclockwise rotation of the rake claw assembly, that is, when the rake claw assembly is about to rake the waste residues such as mulberry residues to the slag discharge port, the slag discharge port will open to receive the waste residues and then discharge them. Specifically in application, the height of this slag discharge port must meet the requirement that when the rake claw assembly rotates to lean against the guardrail plate 2, the bottom edge of the rake claw assembly is flush with the bottom edge of the slag discharge port, so that the waste residues can be discharged better. Each time the waste accumulates to a certain extent at the rake claw assembly, the vibrating screen 1 stops. During the process of the waste rolling downward, the silkworm excrement is located in the lower layer, while the floating residues such as mulberry residues are located on the surface layer. After roughly raking the surface mulberry residues, the vibrating screen 1 starts again.

[0028] As a specific implementation structure, such as Figures 3-4 , this rake claw assembly includes a cross plate 4 and a number of rake teeth 5 fixed to the bottom surface of the cross plate 4 and arranged at intervals along the length direction of the cross plate 4 to clean waste residues such as mulberry residues. During production, this rake tooth 5 can be of a rod-like structure, and the bottom end of the rake tooth 5 is spherical, which can better contact the residual silkworm excrement and avoid scratching the silkworm excrement and causing it to crack further. More specifically, a gear shaft 8 parallel to the width direction of the flat plate 18 is fixed to the upper part of one end of this cross plate 4. This gear shaft 8 is rotatably installed at the bottom of a hinge bracket, and a first bevel gear 7 is fixed to the end of the gear shaft 8. The first bevel gear 7 meshes with a second bevel gear 6 fixed to the side wall of the column 3, and the axis of the second bevel gear 6 is vertically arranged so that the first bevel gear 7 can rotate around the second bevel gear 6. One end of the hinge bracket is hinged and installed inside the side wall of the column 3, and the lower part of the other end is hinged to the top of the cross plate 4 through a hinge 9 to improve the stable reliability of the movement of the cross plate 4, etc.

[0029] Such as Figures 1-3 shown, in this embodiment, its hinge bracket includes a bushing 12 and a cross arm 11 fixed to the bushing 12. The bushing 12 is rotatably sleeved with a hinge post 13 vertically fixed in the column 3 to achieve hinge installation, and the cross arm 11 is arranged parallel to the cross plate 4. The cross arm 11 is fixed to one page of the hinge 9 and a hinge sleeve 16 respectively through two connecting rods 10. The other page of the hinge 9 is fixed to the cross plate 4, and the hinge sleeve 16 is used to install the above-mentioned gear shaft 8. Specifically, such as Figure 2 , this hinge sleeve 16 is a tubular structure with a strip-shaped opening on one side, and the strip-shaped opening runs through both ends of the hinge sleeve 16. The gear shaft 8 is rotatably installed in the hinge sleeve 16, and the top surface of the cross plate 4 extends into the strip-shaped opening and is fixed integrally with the gear shaft 8, and the cross plate 4 is in the radial direction of the gear shaft 8, so that the cross plate 4 can rotate in the air above the flat plate 18 well.

[0030] Since the rake claw assembly rotates toward the uphill side during the rotation process, its hinged end will touch the surface of the flat plate 18, or touch the slope first. Therefore, the gap between the rake claw and the flat plate 18 should be made larger, which is not convenient for fully raking away the waste residue. In order to solve this problem, the rake claw assembly can be as close to the flat plate 18 as possible. In particular, in this embodiment, the cross plate 4 includes an outer plate 402 and an inner plate 401. The inner plate 401 is slidably mounted in the mounting cavity at the bottom end of the outer plate 402, that is, it can make planar motion in the mounting cavity, and the inner plate 401 is hingedly connected to the outer plate 402 by one end of the second bevel gear 6. A driven gear 15 is fixed on the hinge shaft of the two. The driven gear 15 is engaged with the driving gear 14 driven by a micro motor (not shown in the figure) fixed on the outer plate 402, so that the inner plate 401 can be flipped upward, and then the lift change over the above-mentioned slope is passed to smoothly rake away the waste residue. In addition, the articulated column 13 is connected to the main shaft of a power motor 19 installed on the column 3, and the entire rake claw assembly is rotated by driving the articulated column 13, and the power motor 19 is controlled in linkage with the micro motor. Specifically, its linkage mode requires that when the rake claw assembly rotates toward the slag discharge port, the inner plate 401 rotates counterclockwise and further rises accordingly, and when the rake claw assembly approaches the guardrail plate 2, the bottom end of the rake teeth 5 is not lower than the lower edge of the slag discharge port, thereby achieving the cleaning of the waste slag. In practice, the power motor 19 and its linked micro motor can be opened and closed as needed. If necessary, the opening and closing of the door of the slag discharge port is also included in the linkage control as mentioned above. As for the number of starts, it depends on the actual waste situation, which can be automatic or manual.

[0031] In the above embodiments, Figure 2 As shown, there can be a pad 17 near the slag discharge port, the pad 17 is fixed on the column 3, and the flat plate 18 is partially raised to cover the pad 17 and extend downward, so that the raised part is positioned by the pad 17 and acts as a raised portion, and the top surface of the raised portion shall not exceed the lower edge of the slag discharge port, so that it can be well avoided that the waste is not easy to be discharged through the slag discharge port during normal transportation, and it is not easy to rush to the vicinity of the slag discharge port. As a supplementary structural design, the side of the column 3 is fixedly fitted with the guardrail board 2, the two side surfaces of the flat plate 18 are in sliding contact with the two guardrail boards 2, and the bottom end of the column 3 is in sliding contact with the flat plate 18. The purpose of this is to shake the flat plate 18 along the length direction of the flat plate 18 when necessary, or pull the flat plate 18 to clean the flat plate 18.
