Description

Technical Field

[0001] The present application relates to the technical field of forage drying, and in particular to a forage drying device. Background Art

[0002] Forage grass generally refers to grass or other herbaceous plants for livestock. Forage grass has strong regeneration ability and can be harvested many times a year. It is rich in various trace elements and vitamins, so it has become the first choice for raising livestock. With the continuous development of the animal husbandry industry, the forage industry has also been continuously developed. In the production of forage grass, it needs to go through a variety of processing techniques. Before processing, in order to avoid rotting due to excessive moisture in the forage grass, it is usually dried to remove the moisture.

[0003] At present, the drying of forage is mainly divided into two categories: artificial drying and natural drying. Natural drying does not require special equipment, which makes its drying cost lower. Therefore, natural drying has become the main way of drying forage. Natural drying usually places the forage on an open ground and dries it through sun exposure and natural air drying. This has limited utilization of sunlight, and the forage needs to be turned over at regular intervals during the drying process, which makes its drying efficiency low. In addition, there is no time to store the forage on rainy days, so it is more likely to mold after getting damp, which is not conducive to storage. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0026] refer to Figures 1 to 4 The present application provides a forage drying device, comprising:

[0027] The box body 100 has a door 101 hinged on one side of the box body 100, wherein the door 101 is sealed and hinged with the box body 100. In addition, a handle is provided on the door 101 for facilitating opening or closing the door 101.

[0028] The clamping frame 200, the two opposite sides of the clamping frame 200 are rotatably connected to the inner wall of the box body 100 through the fixed shaft 300, one end of the fixed shaft 300 away from the clamping frame 200 penetrates the box body 100 and is connected to a driving member 301, and a grid 201 is arranged in the clamping frame 200 and a strapping belt 202 is arranged thereon; wherein the driving member 301 can be a driving handle or a driving motor, which can be selected according to actual needs, therefore, this application does not make specific restrictions on it. The strapping belt 202 has a certain flexibility and is resistant to high temperatures, and can be made of nylon, polyamide, polypropylene and the like, in order to ensure that while the strapping belt 202 fixes the grass on the clamping frame 200, its flexibility and strapping performance are not affected by the hot air in the box body 100, thereby ensuring the strapping performance of the strapping belt 202. In addition, there may be multiple clamping frames 200, and the multiple fixed shafts 300 connected to each clamping frame 200 are connected in a transmission connection (for example, through a gear transmission connection), which can be specifically set according to actual conditions, and this application does not make any specific limitations on it.

[0029] The receiving tank 400 is provided with a solar heat collecting panel 401 at the top of the receiving tank 400, and the receiving tank 400 is connected with an air supply pipe 402 and is connected with the box body 100 through a hot air pipe 500, and one end of the hot air pipe 500 away from the receiving tank 400 is connected with the side wall of the box body 100 near its bottom, and an air pump 501 is provided on the hot air pipe 500. The top of the receiving tank 400 is open, and the lower surface of the solar heat collecting panel 401 is sealed and connected with the top of the receiving tank 400, which can not only ensure that the air entering the receiving tank 400 from the air supply pipe 402 will not leak, but also the solar heat collecting panel 401 is connected with the receiving tank 400 so that the solar heat collecting panel 401 can directly heat the air in the receiving tank 400, so that the air in the receiving tank 400 is quickly heated, thereby improving the heating efficiency of the air in the receiving tank 400. The air entering the containing tank 400 exchanges heat with the solar energy absorbed and concentrated by the solar thermal collecting panel 401, and the air is heated. The heated air enters the bottom of the box 100 through the hot air pipe 500 under the power provided by the vacuum pump 501, and the hot air at the inner bottom of the box 100 gradually diffuses to the inner top of the box 100. The grid 201 can also play a role in dispersing the hot air, so that the hot air is in full contact with the grass as much as possible, shortening the drying time of the grass, thereby improving the drying efficiency of the grass.

[0030] The grass drying device provided by the present application absorbs and gathers the heat in the sunlight through the solar thermal collecting panel 401 and heats the air entering the containing tank 400, thereby improving the utilization rate of sunlight (specifically, the existing natural drying method is to directly act on the grass through sunlight and natural wind to achieve grass drying. The sunlight needs to continue to act on the grass for a period of time before the moisture in the grass can be dried. After absorbing sunlight, the temperature of the solar thermal collecting panel 401 rises rapidly, resulting in its own high heat. The heat is then used to heat the air entering the containing tank 400. The temperature of the heated air is higher than the temperature of the natural wind. That is to say, compared with the natural drying method for drying grass, the present application uses the air that has exchanged heat with the solar thermal collecting panel 401 to dry the grass fixed by the strapping belt 202 on the clamping frame 200. The heated air is then introduced into the box body 100 from the bottom of the box body 100, and the clamping frame 200 in the box body 100 clamps the grass and fixes the grass by the strapping belt 202. The fixed shaft 300 is driven to rotate by the driving member 301, and the fixed shaft 300 drives the clamping frame 200 and the grass fixed by the strapping belt 202 on the clamping frame 200 to rotate during the rotation. During the rotation, the grass is fully in contact with the hot air diffused upward from the bottom of the box body 100, so that the grass is dried as quickly as possible, thereby improving the drying efficiency of the grass. After the grass is dried, the box door 101 and the strapping belt 202 can be opened to take out the dried grass from the box body 100 and store it, thereby improving the convenience of storing the dried grass.

[0031] In some embodiments, reference Figure 1 , a temperature sensor is provided on the inner wall of the box 100 in the present application; wherein, since the drying temperature of the grass is usually between 50°C and 60°C, the moisture inside the grass can be effectively evaporated within this temperature range to maintain its nutritional value and quality. Too high a temperature may cause the grass to be over-dried and nutrients to be lost; too low a temperature will prolong the drying time, increase energy consumption and production costs. Therefore, 50°C-60°C is the ideal temperature range for grass drying. The temperature sensor can be used to detect the temperature inside the box during the grass drying process. The specifications and models of the temperature sensor can be set according to actual needs, and the present application does not specifically limit it.

[0032] A first flow regulating valve 4021 is provided on the air supply pipe 402, and a second flow regulating valve 502 is provided on the pipe body of the hot air pipe 500 close to the box 100. The first flow regulating valve 4021 is used to regulate the flow of air entering the containing tank 400 through the air supply pipe 402, and the second flow regulating valve 502 is used to regulate the flow of hot air entering the box 100 through the hot air pipe 500. The opening and closing or opening degree of the first flow regulating valve 4021 and the second flow regulating valve 502 are regulated according to the temperature value detected by the temperature sensor, so that the temperature in the box 100 is always maintained between 50°C and 60°C, so that the nutrients contained in the grass will not be lost while the grass is dried.

[0033] In some embodiments, reference Figure 1 The side wall of the upper section of the box 100 in the present application is connected with a safety valve 102. The safety valve 102 belongs to the automatic valve category, which is a special valve whose opening and closing parts are in a normally closed state under the action of external force. When the medium pressure in the equipment or pipeline exceeds the specified value, the medium is discharged to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value.

[0034] In the above embodiment, when the air pressure generated by the hot air in the box 100 is greater than the maximum pressure that the box 100 itself can withstand, the safety valve 102 opens, and the hot air in the box 100 is discharged until the pressure in the box 100 is less than the maximum pressure that the box 100 can withstand, and then the safety valve 102 closes, thereby ensuring the safety of the box 100 during the drying process of forage.

[0035] In some embodiments, reference Figure 4In the present application, one end of the hot air pipe 500 connected to the box 100 extends into the box 100 and is provided with a first baffle 503. The hot air pipe 500 is located in the box 100 and is connected to a plurality of branch pipes 504. Each branch pipe 504 is provided with a second baffle 5041 at one end away from the hot air pipe 500. The hot air pipe 500 is located in the box 100 and each branch pipe 504 is provided with a plurality of upward jet holes 505. The hot air pipe 500 is provided with a plurality of upward jet holes 505, a plurality of branch pipes 504, and a plurality of upward jet holes 505 on each branch pipe 504, so that the hot air entering the box 100 through the hot air pipe 500 can be evenly dispersed on the inner bottom of the box 100 and spread upward, thereby increasing the contact area between the grass and the hot air, so that the grass can be quickly heated, thereby improving the drying efficiency of the grass. In addition, the number of branch pipes 504, the number of jet holes 505 on the pipe body of the hot air pipe 500 located in the box body 100, the number of jet holes 505 opened on each branch pipe 504, and the aperture of each jet hole 505 can all be set according to actual conditions. Therefore, this application does not make specific limitations on them.

[0036] In some embodiments, reference Figure 2 In the present application, a plurality of mutually parallel first partitions 403 are arranged in intervals in the receiving groove 400, one end of each first partition 403 is arranged on the inner wall of the receiving groove 400 and the other end thereof is a first preset distance 600 from the inner wall of the receiving groove 400, and a second partition 404 is arranged between each two adjacent first partitions 403 and is parallel to the first partition 404, one end of each second partition 404 is arranged on the inner wall of the receiving groove 400 and the other end thereof is a second preset distance 700 from the inner wall of the receiving groove 400; wherein, the first preset distance 600 and the second preset distance 700 are intended to allow air to circulate in the receiving groove 400, therefore, the vertical distances of the first preset distance 600 and the second preset distance 700 can be set according to real-time needs, and the present application does not make specific limitations on them.

[0037] The heights of the first baffles 403 and the second baffles 404 are matched with the height of the receiving tank 400, and one end of each first baffle 403 and one end of each second baffle 404 are respectively connected to the two opposite inner side walls of the receiving tank 400. The arrangement of the plurality of first baffles 403, the plurality of second baffles 404, and the first baffles 403 and the second baffles 404 allows the air to diffuse in an S-shape in the receiving tank 400, thereby increasing the residence time of the air in the receiving tank 400, so that the air in the receiving tank 400 can fully exchange heat with the heat absorbed and collected by the solar thermal collector 401, thereby increasing the heat exchange efficiency of the air in the receiving tank 400.

[0038] In some embodiments, reference Figure 1 In the present application, an angle adjustment member 800 is provided between the top surface of the box 100 and the bottom surface of the receiving groove 400, and the angle adjustment member 800 is used to synchronously adjust the inclination angle of the solar collector plate 401 relative to the top surface of the box 100. The angle adjustment member 800 can be a hydraulic cylinder, a pneumatic cylinder, an electric push rod, etc., and can be set according to actual use conditions. Therefore, the present application does not further limit the specific form of the angle adjustment member 800.

[0039] In one possible implementation, the angle adjustment member 800 may include two telescopic rods, the fixed end of each telescopic rod is fixedly connected to the top surface of the box body 100, and the telescopic end of each telescopic rod is hinged to the bottom surface of the accommodating groove 400, so as to facilitate adjusting the inclination angle of the solar collector panel 401 on the top of the accommodating groove 400 relative to the box body 100.

[0040] In the above embodiment, when the telescopic heights of the two telescopic rods are consistent, the solar thermal collecting panel 401 is in a horizontal state. At this time, the position of the solar thermal collecting panel 401 is more suitable for noon, and according to the direction of sunlight in the morning or afternoon, the telescopic height of the telescopic end of one of the telescopic rods is greater than the telescopic height of the telescopic end of the other telescopic rod, so that the solar thermal collecting panel 401 is in an inclined state compared to the box body 100, and the surface of the solar thermal collecting panel 401 is always inclined toward the direction of sunlight. In this way, the solar thermal collecting panel 401 can always face the direction of sunlight, and the heat in the sunlight can be utilized to the greatest extent, so that the air in the containing tank 400 can be quickly heated, which can shorten the drying time of the grass, thereby improving the drying efficiency of the grass and maximizing the utilization of solar energy.

[0041] In some embodiments, reference Figure 1 The bottom of the box 100 in the present application is provided with a universal wheel 103 with a lock. The box 100 is usually located close to the location where the hay is stored or the equipment for further processing. The universal wheel 103 with a lock can move the box 100 close to the location where the hay is stored or the equipment for further processing, thereby improving the convenience of the movement of the box 100 and making the movement of the box 100 more labor-saving.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
