Description

Technical Field

[0001] The present invention relates to a feeding device, and more particularly to a feed conveying device for breeding. Background Art

[0002] In some current farms, feeding devices are often used to transport feed to feed livestock. However, most farms currently use fixed-ground feed troughs, which are then transported by three-wheeled spreaders or rail-mounted feed trucks. Some farms also use traditional industrial belt conveyors for feed transportation, which can only achieve semi-mechanized feeding. When faced with the leftover feed in the troughs consumed by livestock, there is nothing that can be done. These feeding methods often result in problems such as the inability to promptly recover the leftover feed and the inability to clean the troughs in a timely manner. If the troughs are not cleaned in a timely manner, the remaining feed in the troughs will mold and deteriorate, destroying the various nutrients in the moldy feed, reducing the nutritional quality of the feed, or even completely losing its value.

[0003] When livestock and poultry consume moldy, spoiled feed, their growth rate is reduced and their palatability is affected to a certain extent, leading to a decrease in feed intake and a significant prolongation of their growth cycle. Consuming feed containing mycotoxins can weaken their immune systems, interfere with vaccination and acquired immunity, and induce various diseases. Mycotoxins can also harm their liver and kidney function, cause intestinal problems, and affect their digestive system.

[0004] Feed mold can also affect the reproductive performance of livestock. For example, deoxynivalenol and zeaxene produced by Fusarium fungi and aflatoxin produced by Aspergillus flavus can cause symptoms such as scrotal redness and swelling, uterine dilation and swelling, and ovarian atrophy in livestock and poultry, leading to prolonged estrus cycles and decreased reproductive rates in female animals, and shrinkage of male livestock testicles, resulting in "feminization".

[0005] Therefore, farmers use extensive amounts of antifungal agents to prevent mold in feed during the breeding process. Mycotoxins and their metabolites produced by residual feed can remain in livestock and poultry products and enter the human body through the food chain, posing a serious threat to human health. Diseases enter the body through the mouth, so promptly cleaning and disinfecting feed troughs is crucial for preventing livestock from consuming moldy and spoiled feed. Summary of the Invention

[0006] In order to solve the deficiencies in the above-mentioned background technology, the present invention provides a feeding device for aquaculture that can automatically return materials and achieve automatic cleaning and disinfection effects.

[0007] To achieve the above-mentioned purpose, the present invention provides a feeding device for aquaculture. The feeding device for aquaculture comprises: a frame, a rolling device arranged at the first end of the frame, an opening device arranged at the second end of the frame, and a conveyor belt. A trough slide is arranged on the upper side of the frame, and a return channel is arranged on the lower side of the frame. The conveyor belt is wound around the trough slide, the rolling device, the return channel and the opening device. The conveyor belt is made of elastic material, preferably rubber material or PVC. The rolling device comprises a rolling drum and two first baffles arranged on the rolling drum. The conveyor belt passes through the rolling channel formed between the two first baffles. The width of the rolling channel is smaller than the width of the trough slide. In this way, when the conveyor belt moves from the trough slide to the rolling device, the cross-section of the conveyor belt gradually changes from an open state to a sealed rolled state.

[0008] The circle-opening device includes a circle-opening drum and two second baffles arranged on the circle-opening drum. The conveyor belt passes through the circle-opening channel formed between the two second baffles. The width of the circle-opening channel is greater than the width of the return channel. In this way, the conveyor belt can gradually become an open state by relying on its own elasticity when moving from the return channel to the circle-opening device.

[0009] The rolled state of the conveyor belt described in the present invention refers to the state in which the two sides of the conveyor belt are in contact with each other to form a sealed cross-section, including the state in which the two sides of the conveyor belt are overlapped and spliced. The present invention does not specifically limit the cross-sectional shape of the conveyor belt in the rolled state. It can be elliptical, circular or other irregular closed shapes depending on the amount of internal material and the tightness of the conveyor belt.

[0010] The open state of the conveyor belt described in the present invention corresponds to the rolled state of the conveyor belt, which means that there is no contact between the two side edges of the conveyor belt to form a seal. There is no specific limitation on its specific shape. Generally, the conveyor belt needs to be in a fitting relationship with the trough slide. Therefore, when the conveyor belt is in an open state when conveying materials, its shape is preferably consistent with the trough slide.

[0011] The "rolling channel" in the present invention refers to the channel on the rolling device through which the conveyor belt passes, specifically, the annular channel on the rolling drum surrounded by two first baffles. Similarly, the "opening channel" in the present invention refers to the channel on the opening device through which the conveyor belt passes, generally, the annular channel on the opening drum surrounded by two second baffles.

[0012] The first end and the second end of the rack in the present invention refer to the corresponding two ends of the rack, and do not distinguish between front and back positions.

[0013] Furthermore, the winding device further comprises a belt pressing roller group, the belt pressing roller group is in contact with a side of the conveyor belt facing the material trough slideway, the belt pressing roller group comprises a left belt pressing roller group and a right belt pressing roller group, and the left belt pressing roller group and the right belt pressing roller group are arranged one high and one low, so that not only the conveyor belt can be changed into a rolled state with a sealed cross section when passing through the winding device, but also the two sides of the conveyor belt can be overlapped in the rolled state, and the overlapping state of the two sides of the conveyor belt can ensure that the remaining material will not spill out when the conveyor belt is located in the return channel below the frame;

[0014] Furthermore, the return channel is a cylindrical channel, and a gradually widening channel is arranged between the return channel and the circle-opening device. The width of the gradually widening channel gradually increases from the return channel to the circle-opening device, so that the conveyor belt will gradually change to a downward-opening unloading state by relying on its own elasticity as the width of the gradually widening channel gradually increases. One or more rollers are arranged under the gradually widening channel, and the arrangement of the rollers can significantly reduce the friction force on the conveyor belt.

[0015] The unloading state of the conveyor belt described in the present invention means that the cross section of the conveyor belt is open, and the opening is facing downward.

[0016] Furthermore, pulleys are provided on the trough slide and the return channel. The pulleys can effectively prevent wave resistance generated by the conveyor belt during operation, and can also make the conveyance of feed on the conveyor belt more efficient, stable and smooth.

[0017] Furthermore, the cross-section of the trough slide is arc-shaped, and the cross-section of the return channel is elliptical. Setting them to arc-shaped and elliptical shapes not only facilitates the fitting of the conveyor belt with the trough slide and the return channel, but also helps to reduce friction and wear.

[0018] Furthermore, a plurality of intermediate orifice plates are provided on the frame, and the intermediate orifice plates can better fix and support the material trough slide and the return channel.

[0019] Furthermore, a limiting roller assembly is provided on the side of the trough slideway to cooperate with the side edge of the conveyor belt. The limiting roller assembly contacts the edge of the conveyor belt to prevent the conveyor belt from swinging back and forth significantly and wearing the edge during operation. The limiting roller assembly includes a left limiting roller assembly and a right limiting roller assembly.

[0020] The first baffles described in the present invention are two baffles disposed on the winding drum, and are used to form an annular winding channel through which the conveyor belt passes. Their specific shape is not particularly limited, as long as it is sufficient to allow the conveyor belt to pass through. Similarly, the second baffles described in the present invention are two baffles disposed on the open-circular drum, and are used to form an annular open-circular channel through which the conveyor belt passes. Their specific shape is not particularly limited, as long as it is sufficient to allow the conveyor belt to pass through.

[0021] Furthermore, the cross-section of the rolling channel formed between the two first baffles is arc-shaped. Preferably, the two first baffles can be integrally formed into a first bushing fixedly mounted on the rolling drum. Since the first bushing is fixedly mounted on the rolling drum, it can rotate with the rotation of the opening drum and can further drive the conveyor belt to rotate.

[0022] Furthermore, the cross-section of the open circular channel formed between the two second baffles is arc-shaped. Preferably, the two second baffles can be integrally formed as a second bushing fixedly mounted on the winding drum. Since the second bushing is fixedly mounted on the open circular drum, it can rotate with the rotation of the open circular drum and can further drive the conveyor belt to rotate.

[0023] Furthermore, the first bushing and the second bushing are made of polyurethane material, rubber or epoxy resin. Preferably, the first bushing and the second bushing are made of polyurethane material, which not only has greater friction but also has better wear resistance.

[0024] Furthermore, the feeding device for aquaculture further includes a power unit for providing power to the winding drum and / or the unwinding drum. When the power unit is activated, it can drive the winding drum and the unwinding drum to rotate, thereby driving the conveyor belt to continuously move. Preferably, the power unit is a motor.

[0025] Furthermore, the feeding device for breeding also includes a feed receiving bin, which is located above the second end of the frame and is used to feed the feed into the feed trough slide.

[0026] Furthermore, a discharge device is provided below the frame, and the discharge device is used to receive the remaining materials. Preferably, the discharge device is provided at the opening of the conveyor belt in the discharge state.

[0027] Furthermore, the feeding device for breeding also includes a cleaning device, which includes a cleaning roller and a brush arranged on the roller, and the brush contacts the conveyor belt to clean the conveyor belt. Preferably, the cleaning device is arranged on the outside of the circle-opening device.

[0028] Furthermore, the feeding device for aquaculture further comprises an ultraviolet disinfection device, which is used to sterilize and disinfect the conveyor belt. Preferably, the ultraviolet disinfection device is arranged at the second end of the frame.

[0029] Furthermore, because the frame and conveyor belt of the feeding device for farming of the present invention can be set to different lengths as needed, the feeding device for farming also includes a distance control device for controlling the feeding distance and automatically shutting down the feeding device when the feed on the conveyor belt reaches a set position. Furthermore, the feeding device also includes a material weighing device for measuring the amount of feed fed.

[0030] Furthermore, the feeding device for breeding also includes a monitoring camera device, which is used to monitor the entire process of feed transportation, feeding, remaining material return, feed trough cleaning, disinfection, etc. in real time.

[0031] Furthermore, the feeding device for breeding also includes an electrical control device, which is used to control operations such as feeding, returning, cleaning, disinfection, and monitoring of the feeding device.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] The feeding device for livestock farming of the present invention utilizes a coiling device to enable the conveyor belt to change from an arc-shaped open state during feeding to a sealed coiled state during return feeding. This prevents the remaining material from leaking when passing through the return channel. In particular, the left and right limiting roller assemblies, one high and one low, enable the conveyor belt to overlap on both sides when in the coiled state, effectively preventing the remaining material from leaking in the return channel. Simultaneously, the present invention also utilizes an opening device to enable the conveyor belt to change from a sealed coiled state to an arc-shaped open state, thereby facilitating the operations of livestock feeding, feeding, and returning.

[0034] The present invention adopts both a rolling device and an opening device, which can enable the conveyor belt to continuously switch between an arc-shaped open state and a sealed rolled state. When feeding again, the conveyor belt in the open state in the trough slide can be converted into a sealed rolled state, and the remaining feed can be transported to the other end of the frame and transported to the unloading device, making the operation of the conveyor belt more convenient and automated when the livestock are feeding and when the remaining materials are recovered.

[0035] At the same time, the present invention can significantly reduce the power consumption of the entire equipment by arranging multiple pulleys on the material trough slide and the return channel, and the energy-saving effect is obvious. According to the test results, the original 16-meter conveyor required a 4-kilowatt power device, but now a 2-kilowatt power device can easily complete it.

[0036] The feeding device for breeding of the present invention has a wide range of application scenarios and can be widely used in large-scale breeding sites such as sheep breeding, cattle breeding, pig breeding, and chicken breeding. It also has a great driving and promoting effect on the scale and mechanization of the domestic breeding industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited by the specific embodiments. All features disclosed in this specification, except for mutually exclusive features and / or steps, can be combined in any manner. Unless otherwise expressly indicated, throughout the specification and claims, the term "comprise" or its variations such as "comprises" or "comprising" will be understood to include the stated elements or components without excluding other elements or other components.

[0047] like Figure 1-4 As shown, the feeding device for farming in this embodiment includes a frame 1, a rubber conveyor belt 2, a rolling device 3 provided at the head of the frame 1, a rounding device 4 provided at the tail of the frame 1, a motor for providing power to the feeding device, and a cleaning device 7 for cleaning the conveyor belt. A circular arc-shaped trough slide 11 is provided on the upper side of the frame 1, and an elliptical cylindrical return channel 12 is provided on the lower side of the frame 1. A gradually widening channel 44 is provided between the return channel 12 and the rounding device 4, and a plurality of rollers 45 are provided under the gradually widening channel 44. The rubber conveyor belt 2 is wound around the trough slide 11, the rolling device 3, the return channel 12, and the rounding device 4, and rotates counterclockwise driven by the motor. A plurality of intermediate orifice plates 13 are provided on the frame 1 to support the trough slide 11 and the return channel 12. Pulleys 14 are provided on the trough chute 11 and the return channel 12 to reduce friction and prevent wear when the rubber conveyor belt 2 is in contact with the trough chute 11 and the return channel 12. A cleaning device 7 is provided on the outside of the circle-opening device 4 and includes a cleaning roller 71 and a brush 72. The brush 72 contacts the rubber conveyor belt 2 to clean it while it is being conveyed.

[0048] At the same time, a limiting roller group 5 is provided on the side of the trough slide 11 to cooperate with the side edge of the rubber conveyor belt 2. The limiting roller group 5 includes a left limiting roller group 5 and a right limiting roller group 5, which respectively contact the two side edges of the rubber conveyor belt 2, so as to prevent the conveyor belt 2 from swinging back and forth and wearing the edge parts during operation.

[0049] The structure of the rolling device 3 in this embodiment is as follows Figure 5-6As shown, it includes a winding drum 31, a belt-holding roller group 34, and a first sleeve 33 made of polyurethane material fixedly mounted on an open drum 41. The left and right sides of the first sleeve 33 are first baffles 32. A winding channel for the rubber conveyor belt 2 to pass through is formed between the two first baffles 32. The cross-section of the winding channel is arc-shaped, and the width of the winding channel is smaller than the width of the trough slide 11. Since the width of the conveyor belt 2 is fixed, this allows the rubber conveyor belt 2 to transition from an open state to a rolled state. The belt-holding roller group 34 includes a left belt-holding roller group 341 and a right belt-holding roller group 342. The left belt-holding roller group 341 is positioned higher than the right belt-holding roller group 342. Both of them are in contact with the side of the rubber conveyor belt 2 facing the trough slide 11. When the motor drives the winding drum 31 to rotate, the rubber conveyor belt 2's cross-section gradually changes from an open state to a sealed, coiled state due to the action of the belt-holding roller assembly 34 as it moves from the trough chute 11 to the winding device 3. The width of the rubber conveyor belt 2 should be moderate and can be adjusted to the dimensions of the trough chute 11 and the return channel 12 to ensure that it can form a sealed, coiled state in the return channel. Furthermore, because the left belt-holding roller assembly 34134 is positioned higher than the right belt-holding roller assembly 34, the two sides of the rubber conveyor belt 2 can overlap when coiled, thereby preventing any excess material from spilling out of the conveyor belt 2 within the return channel 12.

[0050] The structure of the circle-opening device 4 of this embodiment is as follows Figure 7-8 As shown, it includes an open circular roller 41 and a second sleeve 43 made of polyurethane material fixedly mounted on the open circular roller 41. The left and right sides of the second sleeve 43 are second baffles 42. A ring-shaped open circular channel for the rubber conveyor belt 2 to pass through is formed between the two second baffles 42. The width of the open circular channel is greater than the trough slide 11. At the same time, since a gradually widening channel 44 with a gradually increasing width is provided between the return channel 12 and the open circular channel, multiple rollers are provided under the gradually widening channel 44. The gradually widening channel 44 cooperates with the open circular device 4, so that when the rubber conveyor belt 2 passes through the return channel 12, the gradually widening channel 44 and the open circular channel on the first sleeve 33 in sequence, it relies on its own elasticity to gradually become an open downward state. At the same time, a unloading device 9 is provided at the downward opening, and the remaining feed can fall into the unloading device 9 from here.

[0051] At the same time, the feeding device for breeding in this embodiment also includes a feeding bin 8 and an ultraviolet disinfection device 10 located above the tail of the frame 1, wherein the feeding bin 8 is used to transport the feed to the rubber conveyor belt 2 in the trough slide 11, and the ultraviolet disinfection device 10 is used to sterilize and disinfect the conveyor belt 2 before receiving the material.

[0052] The feeding device for breeding in this embodiment also includes a distance control device, a material weighing device, a monitoring camera device, and an electrical control device, which are not shown in the accompanying drawings. They can be set at different positions of the frame 1 according to specific circumstances, wherein the distance control device is used to realize the control of the feeding distance, and the feeding device can be automatically shut down when the feed on the conveyor belt 2 reaches the set position. The material weighing device is used to measure the amount of feed fed at one time. The monitoring camera device is used to monitor the entire process of feed transportation, feeding, remaining material return, trough cleaning, disinfection, etc. in real time, so that abnormal problems can be handled in time. The electrical control device is used to control the feeding, returning, cleaning, disinfection, monitoring and other operations of the feeding device.

[0053] The specific operation process of this embodiment is as follows:

[0054] The feeding mechanism is activated, and the motor drives the opening and winding drums 41 and 31 to rotate, thereby continuously moving the conveyor belt 2. At this point, the receiving bin 8 is opened, and material continuously falls from the receiving bin 8 onto the rubber conveyor belt 2 in the trough chute 11, where it continues to move forward along with the rubber conveyor belt 2. When the material fills the entire trough chute 11, the feeding distance control device shuts off the feeding mechanism, allowing livestock to access the rubber conveyor belt 2 in the trough chute 11 for feed.

[0055] When the feed on the rubber conveyor belt 2 in the trough chute 11 is eaten by the livestock, the feeding device is started again. At this time, the rubber conveyor belt 2 in the trough chute 11 will move with the remaining feed toward the winding device 3. The winding device 3 is composed of a winding drum 31 and a first bushing 33 arranged on the outside of the winding drum 31. The two sides of the first bushing 33 are first baffles 32. The conveyor belt 2 enters the return channel 12 through the annular winding channel formed by the two first baffles 32. Since the width of the winding channel is smaller than the trough chute 11 in width, the rubber conveyor belt 2 gradually changes from an arc-shaped open state to a sealed rolled state under the combined action of the rolling channel and the left and right pressure roller groups 341 and 342, which are one high and one low. When passing through the rolling device 3 and moving to the bottom of the frame 1, the rubber conveyor belt 2 has already become a rolled state with an elliptical cross-section with overlapping sides. At this time, the remaining feed is wrapped inside the elliptical rubber conveyor belt 2 and continues to move toward the opening device 4 in the return channel 12. Since a gradually widening channel 44 is provided between the return channel 12 below the frame 1 and the opening device 4, the rubber conveyor belt 2 will gradually change to a downward-opening unloading state by relying on its own elasticity when passing through the gradually widening channel 44 and the annular opening channel on the opening drum 41. At the same time, the brush 72 on the cleaning roller 71 contacts the rubber conveyor belt 2 outside the open circular roller 41 to clean the rubber conveyor belt 2. The ultraviolet disinfection device 10 also disinfects the cleaned conveyor belt 2 to facilitate the re-receiving and conveying of new feed. During the above-mentioned entire operation process, the operator can control the ultraviolet disinfection device, distance control device, material weighing device, monitoring camera device and other devices through the electrical control device to perform specific operations according to specific needs.
