Description

Technical Field

[0001] The present invention relates to the technical field of drying devices, and particularly to a forage drying device for livestock farming. Background Art

[0002] In the livestock farming industry, forage, as the main feed source for livestock, its quality directly affects the health of livestock and the breeding efficiency. Fresh forage usually has a high water content (about 60%-80%). If directly stored, it is prone to nutrient loss or even toxin production due to fermentation and mildew. Therefore, it is necessary to reduce the water content to a safe range (generally below 15%) through a drying process. The traditional forage drying methods mainly have the following technical defects: The limitations of natural drying. Natural drying depends on weather conditions and is extremely inefficient in rainy, humid or high-latitude regions. Moreover, during the drying process, it is easily contaminated by dust, pests and microorganisms, resulting in a decline in forage quality. In addition, open-air drying occupies a large area of land, with low land utilization rate, which does not meet the requirements of large-scale farming.

[0003] Deficiencies of traditional drying equipment: Although existing drying equipment (such as coal / oil-fired hot blast stoves, drum dryers) can achieve rapid dehydration, there are the following problems: (1) Uneven drying. During the drying process of forage, local overheating or insufficient drying is likely to occur due to stacking or uneven hot air distribution, affecting the quality of the finished product. (2) Serious nutrient loss. For conventional belt dryers, belt chains arranged in multiple upper and lower layers are often used. During the drying and conveying process, problems such as overlapping and stacking also occur between the upper and lower layers, deteriorating the overall drying effect. (3) Poor drying performance of the equipment. Traditional equipment is mainly designed for materials such as grains and forage, and does not fully consider the fluffy characteristics of forage. The circulating drying method adopted can only target the forage on the outer layer of the conveyor belt, and cannot achieve the synchronous drying effect of the moisture in the inner-layer forage with the outer-layer forage, and cannot achieve integrated drying from the inside to the outside. Summary of the Invention

[0004] 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 livestock farming.

[0005] The present invention is realized through the following technical solutions: A forage drying device for livestock farming includes a box body as the drying main body. A conveyor belt is installed inside the box body, and a feeding trough is provided at the front end of the conveyor belt and a discharging trough is provided at the rear end. The upper layer of the conveyor belt is bent by three groups of guiding devices. The guiding devices include a guiding roller b and a guiding roller c located at the top of the conveyor belt, and a guiding roller a located at the bottom of the upper-layer conveyor belt. The conveyor belt is bent at three places to form a slope state; An air outlet device is fixed below the inclined angle of each slope, and an inclined oscillating plate is installed behind the slope. The air outlet of the air outlet device faces the oscillating plate; A heat conduction roller is provided in front of each guiding device. A number of heat conduction columns a are installed on the heat conduction roller. At the end of each heat conduction column a, a heat conduction column b perpendicular to the main body of the heat conduction column a is fixed. The heat conduction roller is connected to a 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 conduction pipes, and the heat conduction pipes are located between the air outlet device and the vibration plate.

[0006] Further, a baffle is installed on the top of the air outlet device. The air outlet device is fixed at both ends of the box body and is communicated with a hot air blower outside the box body through a pipeline.

[0007] Further, a vibration motor is installed in 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 on the inner walls on both sides of the box body.

[0008] Further, the vibration plate is in an oblique angle shape and the bottom is horizontal. A number of ventilation slots are evenly arranged on the vibration plate. The ventilation slots are rounded rectangular holes penetrating from front to back. Oblique angle slots are arranged between each row of ventilation slots on the vibration plate.

[0009] Further, the rotation direction of the heat conduction roller is consistent with the advancing direction of the forage on the conveyor belt. The direction of the heat conduction column b is along the advancing direction of the forage. A heat conduction plate is fixed between every three adjacent heat conduction columns a, and the heat conduction plate is located at the middle position of the heat conduction column a.

[0010] Further, dehumidifying blowers are provided at positions corresponding to each guiding device on the top of the box body. A filter plate is installed at the bottom of the box body, and a number of circulation blowers are fixed below the filter plate.

[0011] Further, the height of the vibration plate is higher than the highest position of the conveyor belt.

[0012] Further, the conveyor belt is driven to rotate by a driving roller, and the driving roller is driven by a main motor outside the box body; The heat conduction roller is driven by a guiding motor on one side, and the linear velocity at the top of the heat conduction column a is greater than the advancing speed of the conveyor belt.

[0013] Further, both ends of the guiding roller a, the guiding roller b, the guiding roller c and the heat conduction roller are rotatably connected to bearing seats on the box body.

[0014] The beneficial effects of the present invention are: The present invention uses three heating methods, namely a heat conduction roller, a heat conduction pipe, and a hot air blower, to dry forage, and the drying effect is obvious. The present invention bends the conveyor belt into three groups of ramp forms. During the process of forage movement, forked heat conduction columns and angled shock plates are used to make the forage tumble, which also ensures that the forage inside is effectively dried. Compared with the conventional flat belt drying device, the present invention has a more efficient drying effect. The present invention can effectively solve the problems of forage accumulation and jamming during the drying process and the problem of insufficient drying of the inner layer of forage.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0018] Accordingly, 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 claimed invention, but merely represents 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 efforts fall within the scope of protection of the present invention.

[0019] Referring Figures 1 to 6 , the present invention includes a box body 1 as a drying main 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 for transporting the forage to be dried. The conveyor mesh belt 3 is a conventional perforated mesh belt rather than an enclosed conveyor belt. An inlet chute 101 is provided at the front end of the conveyor mesh belt 3, and an outlet chute 102 is provided at the rear end. The upper layer of the conveyor mesh belt 3 is bent by three groups of guiding devices, which belong to the key drying area. The guiding devices include a guiding roller b401 and a guiding roller c402 located on the top of the conveyor mesh belt 3, and a guiding 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 state. Referring Figure 4 ; An air outlet device 6 is fixed below the inclined angle of each slope to blow out hot drying air for drying the forage falling on the slope. An inclined shock plate 7 is installed behind the slope. The air outlet of the air outlet device 6 faces the shock plate 7, so that when the forage is blown onto the front end face of the shock plate 7, the shock plate 7 plays a blocking role.

[0020] A heat conducting roller 5 is provided in front of each guiding device. The heat conducting liquid (such as hot oil, etc.) contained therein is prior art and will not be elaborated. A number of heat conducting columns a501 are installed on the heat conducting roller 5. The heat conducting columns a501 are solid columns, and the heat conducting liquid does not penetrate into them. A heat conducting column b502 perpendicular to the main body of the heat conducting column a501 is fixed at the end of each heat conducting column a501. The heat conducting roller 5 is connected to a heating device 504 on the side through a conduit passing through the box body 1. 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, which is prior art and will not be elaborated. Another output port of the heating device 504 is connected to two heat conducting tubes 505. The heat conducting tubes 505 are located between the air outlet device 6 and the shock plate 7. When the forage with more moisture passes through the space between the conveyor mesh belt 3 and the shock plate 7, it is in close contact with the heat conducting tubes 505, and the moisture is dried and evaporated, further improving the drying effect.

[0021] A baffle plate 601 is installed on the top of the air outlet device 6 to prevent the forage from falling into the gap at the rear side of the air outlet device 6. The air outlet device 6 is fixed at both ends of the box body 1 and is communicated with a hot air blower 602 outside the box body 1 through a pipeline; the air outlet device 6 is the air outlet extension and guiding port of the hot air blower 602.

[0022] A vibration motor 703 is installed in the center of the back side of the vibration plate 7 to ensure uniform feeding on the slope to prevent the grass from getting stuck and piling up. Anti-seismic dampers 704 are installed at the four corners, and 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.

[0023] The oscillation plate 7 is in an oblique angle and has a horizontal bottom. Figure 4 The inclination direction of the oscillation plate 7 is that the bottom is biased toward the conveyor mesh belt 3, and 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 in the box, so as to ensure that the ventilation slots 701 are rounded rectangular holes that penetrate from front to back; An oblique 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 oblique 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.

[0024] The rotation direction of the heat-conducting roller 5 is consistent with the traveling direction of the forage on the conveyor mesh belt 3, and the direction of the heat-conducting column b502 is along the traveling direction of the forage. A heat-conducting plate 503 is fixed between three adjacent heat-conducting columns a501. On the one hand, it plays a role of fixed support, and on the other hand, it can make the temperature difference of adjacent heat-conducting columns a501 not large. The softer forage sometimes slides on the front slope of the conveyor mesh belt 3, and the heat-conducting plate 503 will contact the forage and help it to turn over the conveyor mesh belt 3 to a certain extent. Of course, the height of the conveyor mesh 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 columns a501 and b502, and on the other hand, it helps to heat the internal space.

[0025] refer to Figure 4 The heat-conducting column a501 adopts a forked structure, that is, a heat-conducting column b502 is also provided, and 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, and when the hay is located in the position of the guide device (or in the guiding stage), the heat-conducting column b502 is "transversely (tangentially)" inserted to dry the hay, both of which increase the drying area.

[0026] A dehumidification fan 9 is arranged at the position corresponding to each guide device on the top of the box 1, 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 under the filter plate 8 to assist the steam in the box 1 to evaporate upward.

[0027] 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 the slope angle is turned over.

[0028] The conveyor net belt 3 is driven to rotate by the driving roller 2, and the driving roller 2 is driven by the main motor 201 outside the box body 1. The one at the rear end in the figure is a passive roller for backup in case of emergency (such as damage to the main motor 201). The heat conduction roller 5 is driven by the guiding motor 506 on one side. The linear velocity at the top of the heat conduction column a501 is greater than the traveling speed of the conveyor net belt 3. That is, when the forage travels to contact with the heat conduction column a501, it will be flipped by the heat conduction column a501 and the heat conduction column b502 with a faster speed. Since the heat conduction columns a501 are arranged evenly, they are flipped in alignment in the same row when flipping, avoiding the forage being flipped too disorderly.

[0029] Both ends of the guiding roller a4, the guiding roller b401, the guiding roller c402 and the heat conduction roller 5 are rotatably connected to the bearing seats on the box body 1.

[0030] The electric control components for control and power supply, such as the electric control box and the PLC controller, all belong to the prior art, and their electrical connections and examples with the electric control components in the present invention will not be elaborated herein.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention shall be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
