Description

Technical Field

[0001] The present invention relates to the technical field of drying devices, in particular to a forage drying device for animal husbandry. Background Art

[0002] In the livestock farming industry, forage is the primary feed source for livestock, and its quality directly impacts their health and farming profitability. Fresh forage typically has a high moisture content (approximately 60%-80%). Direct storage can lead to nutrient loss and even the production of toxins due to fermentation and mold. Therefore, drying is necessary to reduce the moisture content to a safe range (generally below 15%). Traditional forage drying methods have the following major technical drawbacks: The limitations of natural air drying, which relies on weather conditions and is extremely inefficient in rainy, humid, or high-latitude areas. Furthermore, the drying process is susceptible to contamination by dust, pests, and microorganisms, resulting in a decrease in forage quality. Furthermore, open-air drying occupies large areas, resulting in low land utilization rates and incompatibility with large-scale farming.

[0003] Disadvantages of traditional drying equipment:

[0004] Although existing drying equipment (such as coal-fired / oil-fired hot air furnaces and drum dryers) can achieve rapid dehydration, they have the following problems: (1) Uneven drying. During the drying process, the grass is prone to local overheating or insufficient drying due to accumulation or uneven distribution of hot air, affecting the quality of the finished product. (2) Severe nutrient loss. For conventional mesh belt dryers, mesh belt chains with multiple layers arranged above and below are often used. During the drying and conveying process, the upper and lower layers will also overlap and accumulate, which will deteriorate the overall drying effect. (3) Poor drying performance of the equipment. Traditional equipment is mostly designed for materials such as grains and grass, and does not fully consider the fluffy characteristics of grass. The circulating drying method used can only be used for the outer layer of grass on the conveyor mesh belt. The moisture in the inner layer of grass cannot be dried synchronously with the outer layer of grass, and integrated drying from the inside to the outside cannot be achieved. Summary of the Invention

[0005] In order to make up for the deficiencies in the prior art and achieve the above functions, the present invention provides a forage drying device for animal husbandry.

[0006] The present invention is achieved through the following technical solutions:

[0007] A forage drying device for livestock breeding includes a box body as the drying body, a conveyor mesh belt installed inside the box body, and a feed chute at the front end of the conveyor mesh belt and a discharge chute at the rear end. The upper layer of the conveyor mesh belt is bent by three sets of guide devices, the guide devices including guide rollers b and c located at the top of the conveyor mesh belt, and guide roller a located at the bottom of the upper conveyor mesh belt. The conveyor mesh belt is bent at three locations to form a slope.

[0008] An air outlet device is fixed below the angle of each slope, and an inclined vibration plate is installed behind the slope, with the air outlet of the air outlet device facing the vibration plate;

[0009] A heat-conducting roller is provided in front of each guide device, and several heat-conducting columns a are installed on the heat-conducting roller. A heat-conducting column b perpendicular to the main body of the heat-conducting column a is fixed to the end of each heat-conducting column a. The heat-conducting roller is connected to the heating device on the side through a conduit passing through the box body. The other output port of the heating device is connected to two heat-conducting pipes, and the heat-conducting pipes are located between the air outlet device and the oscillation plate.

[0010] Furthermore, a baffle plate is installed on the top of the air outlet device, and the air outlet device is fixed at both ends of the box body and is connected to the hot air blower outside the box body through a pipeline.

[0011] Furthermore, a vibration motor is installed at the center of the back of the vibration plate, and anti-seismic dampers are installed at the four corners. The other ends of the anti-seismic dampers are fixed to the inner walls on both sides of the box.

[0012] Furthermore, the oscillation plate is in an oblique angle shape and has a horizontal bottom. A plurality of ventilation slots are evenly arranged on the oscillation plate. The ventilation slots are rectangular holes with rounded corners that pass through the front and back.

[0013] Bevel grooves are provided between each row of ventilation slots on the oscillation plate.

[0014] Furthermore, the rotation direction of the heat-conducting roller is consistent with the direction of the grass on the conveyor belt, the direction of the heat-conducting column b is along the direction of the grass, and a heat-conducting plate is fixed between three adjacent heat-conducting columns a, and the heat-conducting plate is located in the middle position of the heat-conducting column a.

[0015] Furthermore, a dehumidification fan is provided at a position corresponding to each guide device on the top of the box, a filter plate is installed at the bottom of the box, and several circulation fans are fixed below the filter plate.

[0016] Furthermore, the height of the oscillation plate is higher than the highest position of the conveyor belt.

[0017] Furthermore, the conveyor belt is driven to rotate by a transmission roller, and the transmission roller is driven by a main motor outside the box;

[0018] The heat-conducting roller is driven by a guide motor on one side, and the linear speed of the top of the heat-conducting column a is greater than the traveling speed of the conveyor belt.

[0019] Furthermore, the guide roller a, guide roller b, guide roller c and heat-conducting roller are all rotatably connected to the bearing seat on the box body through both ends.

[0020] The beneficial effects of the present invention are:

[0021] The present invention adopts three heating methods of heat-conducting rollers, heat-conducting pipes and hot air blowers to dry the grass, and the drying effect is obvious; the present invention bends the conveyor belt into three groups of slopes, and adopts forked heat-conducting columns and angled vibration plates to make the grass churn during the movement of the grass, which also ensures that the grass inside is effectively dried; compared with the conventional, flat-laying mesh belt drying device, the present invention has a more efficient drying effect; the present invention can effectively solve the problems of grass accumulation and jamming during the drying process and the problem of insufficient drying of the inner layer of grass.

[0038] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in a variety of different configurations.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but is merely intended to represent selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0040] refer to Figures 1 to 6 The present invention includes a box body 1 as the drying body. Of course, the box body 1 also has conventional heat preservation and heat insulation functions. A conveyor mesh belt 3 is installed inside the box body 1 to transport the grass to be dried. The conveyor mesh belt 3 is a conventional perforated mesh belt rather than a closed conveyor belt, and a feed trough 101 is provided at the front end of the conveyor mesh belt 3, and a discharge trough 102 is provided at the rear end. The upper layer of the conveyor mesh belt 3 is bent by three groups of guide devices and belongs to the key drying area. The guide device includes a guide roller b401 and a guide roller c402 located at the top of the conveyor mesh belt 3, and a guide roller a4 located at the bottom of the upper conveyor mesh belt 3. The conveyor mesh belt 3 is bent at three places to form a slope. Figure 4 ;

[0041] An air outlet device 6 is fixed below the angle of each slope to blow out dry hot air for drying the grass falling from the slope. An inclined vibration plate 7 is installed behind the slope. The air outlet of the air outlet device 6 is opposite to the vibration plate 7, so that when the grass is blown to the front end surface of the vibration plate 7, the vibration plate 7 acts as a barrier.

[0042] A heat-conducting roller 5 is provided in front of each guide device, and the built-in heat-conducting liquid (such as hot oil, etc.) is the existing technology and will not be described in detail. A number of heat-conducting columns a501 are installed on the heat-conducting roller 5. The heat-conducting column a501 is a solid column, and the heat-conducting liquid is not immersed in it. A heat-conducting column b502 perpendicular to the main body of the heat-conducting column a501 is fixed to the end of each heat-conducting column a501. The heat-conducting roller 5 is connected to the side heating device 504 through a conduit passing through the box body 1, and the heating device 504 plays a heating role. Of course, the conduit outside the box body 1 can be insulated with conventional heat-insulating cotton. This is the existing technology and will not be described in detail. The other output port of the heating device 504 is connected to two heat-conducting pipes 505. The heat-conducting pipes 505 are located between the air outlet device 6 and the vibration plate 7. When the grass with more moisture passes through the space between the conveyor belt 3 and the vibration plate 7, it is in close contact with the heat-conducting pipe 505, and the moisture is dried and evaporated, further improving the drying effect.

[0043] A material baffle 601 is installed on the top of the air outlet device 6 to prevent grass from falling into the gap behind the air outlet device 6. The air outlet device 6 is fixed at both ends of the box body 1 and is connected to the hot air blower 602 outside the box body 1 through a pipeline; the air outlet device 6 is an extension and guide port of the hot air blower 602.

[0044] A vibration motor 703 is installed in the center of the back of the vibration plate 7 to ensure uniform material discharge on the slope to prevent the grass from getting stuck and piling up. Anti-seismic dampers 704 are installed at the four corners. The other ends of the anti-seismic dampers 704 are fixed to the inner walls on both sides of the box body 1 to reduce the vibration of the vibration plate 7 itself from being transmitted to the box body 1 to cause resonance.

[0045] The vibration plate 7 is in an oblique angle and has a horizontal bottom. Figure 4 The inclination direction of the oscillation plate 7 is such that the bottom is biased toward the conveyor belt 3. A plurality of ventilation slots 701 are evenly arranged on the oscillation plate 7 so that hot air can pass through the oscillation plate 7 to circulate within the box, ensuring that the ventilation slots 701 are rounded rectangular holes that penetrate the front and back;

[0046] An angled groove 702 is provided between each row of ventilation slots 701 on the vibration plate 7. When the hay comes into contact with the vibration plate 7, the angled groove 702 shaped like a step will move part of the hay stem, causing it to turn over and be fully dried by the hot air.

[0047] The rotation direction of the heat-conducting roller 5 is consistent with the direction of the grass on the conveyor belt 3. The direction of the heat-conducting column b502 is along the direction of the grass. A heat-conducting plate 503 is fixed between the three adjacent heat-conducting columns a501. On the one hand, it plays a fixed support role. On the other hand, it can make the temperature difference between adjacent heat-conducting columns a501 not large. The grass with a softer texture sometimes slides on the front slope of the conveyor belt 3, and the heat-conducting plate 503 will help it to turn over the conveyor belt 3 to a certain extent by contacting the grass. Of course, the height of the conveyor belt 3 should not be too high, and should be adapted to the horizontal heat-conducting column b502. The heat-conducting plate 503 is located in the middle position of the heat-conducting column a501. On the one hand, the heat-conducting roller 5 can transfer heat to the heat-conducting column a501 and the heat-conducting column b502, and on the other hand, it helps to heat the internal space.

[0048] refer to Figure 4 The heat-conducting column a501 adopts a forked structure, that is, a heat-conducting column b502 is also provided. Its function is: the heat-conducting column a501 is "vertically" inserted by the heat-conducting column a501 before the hay approaches the guide device for internal drying. When the hay is located in the guide device position (or in the guide stage), the heat-conducting column b502 is "horizontally (tangentially)" inserted to dry the hay, which increases the drying area.

[0049] A dehumidification fan 9 is provided at the top of the box 1 at a position corresponding to each guide device, and the evaporated water is discharged through its unified air duct. A filter plate 8 is installed at the bottom of the box 1 to prevent large particles from damaging the fan. Several circulation fans 801 are fixed below the filter plate 8 to assist the steam in the box 1 to evaporate upward.

[0050] The height of the vibration plate 7 is higher than the highest position of the conveyor belt 3 to prevent the grass from being too high and then passing over the vibration plate 7 after turning over at the slope angle.

[0051] The conveyor belt 3 is driven to rotate by the transmission roller 2, which is driven by the main motor 201 outside the box 1. The rear end of the figure is a passive roller, which is used as a backup in an emergency (for example, when the main motor 201 is damaged);

[0052] The heat-conducting roller 5 is driven by a guide motor 506 on one side. The linear speed of the top of the heat-conducting column a501 is greater than the travel speed of the conveyor belt 3. That is, when the hay comes into contact with the heat-conducting column a501, it will be turned over by the faster heat-conducting columns a501 and b502. Since the heat-conducting columns a501 are evenly arranged, they are turned over in the same row to avoid being turned over too messily.

[0053] The guide roller a4, guide roller b401, guide roller c402 and heat-conducting roller 5 are all rotatably connected to the bearing seat on the box body 1 through both ends.

[0054] The electric control components used for control and power supply, such as the electric control box and the PLC controller, are all in the prior art, and their electrical connections and examples with the electric control components in the present invention are not described in detail.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
