Description

Technical field:

[0001] The invention relates to the field of drying equipment, in particular to a continuous forage dryer. Background technology:

[0002] Forage grass refers to grass or other herbaceous plants for livestock to eat, such as the most common alfalfa. Forage grass has strong regeneration ability and can be harvested many times a year. It is rich in various trace elements and vitamins. Wet forage grass is not easy to store. In order to ensure the value of forage grass, it is usually dried. At present, the drying methods of forage grass can be roughly divided into two categories: natural drying and artificial drying.

[0003] The natural drying method does not require special equipment and is largely limited by weather conditions. However, the natural drying efficiency is low, the labor intensity is high, the quality of the hay produced is poor, and the cost is low. The main disadvantage is that a large number of alfalfa leaves will fall off during the natural drying and air-drying process, and the main nutrients of alfalfa are in the alfalfa leaves. A large number of leaf drops will seriously reduce the nutritional quality of alfalfa. The artificial drying method has developed rapidly in the past 30 years. Artificial drying can reduce the loss of nutrients during the natural drying process of forage, so that the nutritional value of forage can be maintained at a high level. Artificial drying mainly includes normal temperature blast drying and high temperature rapid drying. However, these two methods are prone to the loss of nutritional value in the forage during the drying process, and the energy consumption of normal temperature blast drying and high temperature rapid drying is large, mainly because the heat loss cannot be guaranteed and the temperature control is discontinuous. Summary of the invention:

[0004] The main purpose of the present invention is to solve the problems of poor drying effect and high energy consumption caused by fast heat loss and discontinuous temperature control in current drying equipment.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A continuous forage dryer comprises a drying box, a feed inlet, a discharge outlet, an air blocking plate, an air inlet, a hot air blower, a flow guide mechanism and a box cover, wherein the drying boxes are provided with more than two and are sequentially connected to form a multi-stage type, wherein the front end of one drying box is provided with a feed inlet, the middle is a combination of multiple drying boxes, and the rear end of the last drying box is provided with a discharge outlet, and a plurality of transmission rollers are provided inside each drying box, and the transmission rollers mainly play the role of transmitting forage grass, and air blocking plates are fixed on the inner walls of both sides of each drying box, and a semicircular notch is provided on each air blocking plate, and each semicircular notch is connected to the corresponding transmission roller In cooperation, the air blocking plate can prevent the hot air flow from leaking along the inner wall of the drying box, and the hot air flow can only flow upward through the gaps between the transmission rollers, thereby drying the hay. Guide mechanisms are also arranged on both sides of each drying box, and the guide mechanisms are located above the transmission rollers. An air inlet is opened on one side of the bottom of the drying box, and the air inlet is connected to the corresponding hot air blower. The operating power of each hot air blower is different, and the power is reduced one by one, so that the drying temperature in each section of the drying box is gradually reduced, and the temperature can be continuously controlled to ensure the continuity of the hay drying. A box cover is also arranged on the upper part of each drying box.

[0007] Preferably, gears are respectively arranged at both ends of the transmission roller, each adjacent gear is meshed with each other, and the gears are located outside the drying box; dust covers are also arranged on both sides of each drying box, and the gears are all located inside the dust covers.

[0008] Preferably, a support frame is installed on one side of the drying box body, and the support frame is located below the dust cover. A drive motor is also arranged on one side of the dust cover, and the drive motor is installed on the support frame. One end of the drive motor extends into the dust cover and is fixedly connected to one end of one of the transmission rollers in the dust cover, so that power is transmitted to each transmission roller.

[0009] Preferably, the guide mechanism includes a connecting block, a guide plate and a spring, the connecting block is installed on the inner wall of the drying box, and the guide plate is movably connected to the connecting block, one end of the guide plate is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to the inner wall of the drying box, and the guide plate is mainly used to prevent the hay from shifting during the transmission process, thereby causing blockage.

[0010] Preferably, the box cover is movably mounted on the drying box body, and a handle is also installed on one side of the box cover. The box cover can reduce the leakage of hot air flow and is convenient for maintenance.

[0011] Working principle of the present invention:

[0012] The operating power of each hot air blower is set according to actual conditions, and then the box cover is closed and the drive motor is started to rotate the transmission rollers in each section of the drying box. At this time, the hay stalks are passed through each section of the drying box in turn through the feed port. When passing through the interior of each drying box, the hot air flow dries the hay stalks upward along the gap between the transmission rollers. The drying temperature of each section is different, so continuous temperature control is achieved. The guide mechanism during the transmission process is mainly used to prevent the hay stalks from shifting during the transmission process, which may cause blockage.

[0013] The beneficial effects of the present invention are:

[0014] 1. The air blocking plates on both sides of the drying box can prevent the hot air from leaking outward along the inner wall of the drying box. When the hot air flows upward, it will move horizontally when it encounters the bottom of the air blocking plate and can only flow upward through the gaps between the transmission rollers, thus ensuring the drying temperature.

[0015] 2. Multiple drying boxes form multi-stage continuous drying. The operating power of each hot air blower is reduced one by one, so that the drying temperature in each drying box is gradually reduced. The temperature can be continuously controlled, thereby ensuring the continuity of forage drying, reducing energy consumption, and achieving better drying effects. Description of the drawings:

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, 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.

[0025] The present invention provides the following specific embodiments.

[0026] Embodiment 1:

[0027] Reference Figure 1-Figure 7 , a continuous forage dryer comprises a drying box 1, a feed port 2, a discharge port 3, an air blocking plate 4, an air inlet 5, a hot air blower 6, a guide mechanism 7 and a box cover 8, wherein the drying box 1 is provided with more than two and connected in sequence to form a multi-stage type, wherein a feed port 2 is provided at the front end of one of the drying boxes 1, a combination of multiple drying boxes 1 is provided in the middle, and a discharge port 3 is provided at the rear end of the last drying box 1, and a plurality of transmission rollers 9 are provided inside each of the drying boxes 1, and air blocking plates 4 are fixed on the inner walls on both sides of each drying box 1, and each of the air blocking plates 4 is provided with a semicircular notch 10, and each of the semicircular notches 10 cooperates with the corresponding transmission roller 9, and guide mechanisms 7 are also provided on both sides of each drying box 1, and the guide mechanisms 7 are located above the transmission roller 9, and an air inlet 5 is provided on one side of the bottom of the drying box 1, and the air inlet 5 is connected to the corresponding hot air blower 6, and a box cover 8 is also provided on the upper part of each drying box 1.

[0028] Gears 11 are respectively arranged at both ends of the transmission roller 9 , and each adjacent gear 11 is meshed with each other, and the gears 11 are located outside the drying box 1 ; dust covers 12 are also arranged on both sides of each drying box 1 , and the gears 11 are all located inside the dust covers 12 .

[0029] A support frame 13 is installed on one side of the drying box body 1, and the support frame 13 is located below the dust cover 12. A drive motor 14 is also arranged on one side of the dust cover 12, and the drive motor 14 is installed on the support frame 13. One end of the drive motor 14 extends into the dust cover 12 and is fixedly connected to one end of one of the transmission rollers 9 in the dust cover 12.

[0030] During transmission, the driving motor 14 drives one of the transmission rollers 9 to rotate, and the gear 11 on the transmission roller 9 also rotates. Since each adjacent gear 11 is meshed with each other, the power is transmitted to each transmission roller 9 in turn, so that the hay can be moved inside the drying box 1. During the movement, the temperature of each section of the drying box 1 is different and gradually decreases, thereby realizing continuous temperature control. The air blocking plate 4 changes the moving direction of the hot air leaking along the inner wall of the bottom of the drying box 1, so that all the hot air flows upward along the gaps between the transmission rollers 9, thereby reducing the leakage of the hot air flow.

[0031] Embodiment 2:

[0032] The difference from Example 1 is that the guide mechanism 7 includes a connecting block 70, a guide plate 71 and a spring 72, the connecting block 70 is installed on the inner wall of the drying box body 1, and the guide plate 71 is movably connected to the connecting block 70, one end of the guide plate 71 is fixedly connected to one end of the spring 72, and the other end of the spring 72 is fixedly connected to the inner wall of the drying box body 1.

[0033] The box cover 8 is movably mounted on the drying box body 1 , and a handle 15 is also mounted on one side of the box cover 8 .

[0034] The guide plate 71 is set at a certain angle. During the transmission process, once the hay stalk is offset, the edge of the hay stalk will hit the guide plate 71, and the guide plate 71 will compress the spring 72. Under the action of the spring 72, the hay stalk will not be close to the inner wall of the drying box 1, thereby avoiding blockage.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
