Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a hot air drying device for greenhouses. Background Technology

[0002] Vegetables are an essential part of people's daily diet. As a green food, they are often grown in greenhouses. Some vegetables need to be dried and dehydrated in greenhouses after being picked to make dried vegetables, so hot air drying equipment is used.

[0003] In the existing technology, when drying vegetables, multiple vegetables are usually placed still. Therefore, people need to open the device periodically to turn the vegetables so that the hot air can blow better onto the surface of the vegetables. This operation increases people's physical exertion. Moreover, the heat inside the device is lost quickly due to the constant opening of the device, which is not conducive to the drying operation of vegetables and reduces the efficiency of vegetable drying. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a hot air drying device for greenhouses to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A greenhouse hot air drying device includes a drying box with a door hinged to the front. A hot air fan is located at the rear top of the drying box, and a connecting pipe is located at the front end of the hot air fan. An air outlet frame is fixedly connected to the end of the connecting pipe, and multiple sets of air outlet nozzles are located at the bottom of the air outlet frame. A swing mechanism is fixedly connected inside the drying box. The swing mechanism includes a rectangular block, a rotating shaft is located at the top of the rectangular block, a placement plate is located at the top of the rotating shaft, and a placement frame is movably mounted on the surface of the placement plate.

[0007] Preferably, rectangular strips are fixedly connected to the surface of the placement plate near the two side edges, and a connecting block is fixedly connected to the bottom of the placement frame. The surface of the connecting block is provided with a mating groove. By inserting the frame into the connecting block through the mating groove and then pushing it forward, the placement frame and the placement plate can be quickly connected, making it convenient for people to change placement frames of different sizes.

[0008] Preferably, extension plates are fixedly connected to the upper sides of the connecting block. Positioning holes are provided on the surfaces of both the extension plates and the placement plate. Positioning rods are inserted into the positioning holes. There are four sets of positioning rods, which are distributed near the four corners of the surface of the placement plate. By inserting the positioning rods into the positioning holes, the placement frame can be further fixed after installation, preventing the placement frame from falling off the placement plate when the swing mechanism is in use.

[0009] Preferably, magnetic locating plates are fixedly connected to the bottom of the positioning rod and inside the positioning hole located on the surface of the placement plate. The two sets of magnetic locating plates are matched in size. After the positioning rod is inserted into the positioning hole, the two attract each other through the magnetic locating plates, ensuring the stability of the positioning rod after installation and preventing it from falling off during use.

[0010] Preferably, a rectangular piece is fixedly connected to the top of two adjacent sets of positioning rods, and a connecting strip is fixedly connected to the side of the rectangular piece. A protrusion is fixedly connected to the surface of the connecting strip near the edge. The two adjacent sets of positioning rods are connected to each other by the connecting strip. Therefore, multiple sets of positioning rods can be disassembled and assembled by only one operation, reducing the time required for disassembly and assembly.

[0011] Preferably, the drying oven has limit sockets on both sides near the bottom. The surface of the limit sockets is hinged with a baffle plate via a damping hinge. The surface of the baffle plate is provided with a rubber sealing strip. By providing a baffle plate with a rubber sealing strip, when the baffle plate is closed onto the limit socket, it will be embedded into its inner wall, thereby ensuring the sealing performance after the baffle plate is closed, preventing heat loss from the drying oven, and helping to improve the drying rate of subsequent vegetables.

[0012] Preferably, a pull handle is fixedly connected to the center of the surface of the placement frame. The surface of the pull handle has multiple sets of semi-circular grooves. By using the pull handle, people can easily pull the placement frame out of the placement plate and then pull it out of the limiting socket to retrieve vegetables.

[0013] Preferably, the surface of the door is provided with an installation opening, and a transparent heat-insulating glass is embedded in the inner wall of the installation opening. The transparent heat-insulating glass allows people to see the vegetable processing inside the drying box from the outside.

[0014] The beneficial effects of this utility model are as follows:

[0015] The oscillating mechanism allows the placement plate to swing up and down with the rotation of the shaft under the push of the cylinder, thereby causing the vegetables in the placement frame to move back and forth. This adjusts and moves the placement position of the vegetables, ensuring that multiple sides of the vegetables are exposed to hot air, eliminating the need for manual turning and improving the drying effect of the device.

[0016] By inserting the placement frame into the connecting block through the docking groove, and then pushing it forward, the placement frame and the placement plate can be quickly connected. Then, the positioning rod is inserted into the positioning hole to further fix the placement frame. Since the placement frame is installed by entering and exiting through the limiting socket, the opening of the drying box is smaller when unloading materials. Compared with directly opening the box door, this effectively reduces the heat loss inside and helps to improve the drying rate of vegetables. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] According to an embodiment of the present invention, a hot air drying device for greenhouses is provided.

[0026] Example 1;

[0027] like Figure 1-5 As shown, the greenhouse hot air drying device according to an embodiment of the present utility model includes a drying box 1. The front of the drying box 1 is hinged with a door 2. A hot air fan 3 is provided at the rear of the top of the drying box 1. A connecting pipe 4 is provided at the front end of the hot air fan 3. An air outlet frame is fixedly connected to the end of the connecting pipe 4. Multiple sets of air outlet nozzles 5 are provided at the bottom of the air outlet frame. A swing mechanism 6 is fixedly connected inside the drying box 1. The swing mechanism 6 includes a rectangular block 601. A rotating shaft 602 is provided at the top of the rectangular block 601. A placement plate 603 is provided at the top of the rotating shaft 602. A placement frame 7 is movably installed on the surface of the placement plate 603.

[0028] In this embodiment, rectangular strips 605 are fixedly connected to the surface of the placement plate 603 near the two side edges, and a connecting block 16 is fixedly connected to the bottom of the placement frame 7. The surface of the connecting block 16 is provided with a mating groove 17. By inserting the frame into the connecting block 16 through the mating groove 17 provided on the connecting block 16 and then pushing it forward, the placement frame 7 and the placement plate 603 can be quickly connected, making it convenient for people to replace placement frames 7 of different sizes.

[0029] In this embodiment, extension plates 11 are fixedly connected to the upper sides of the connecting block 16. Positioning holes 12 are provided on the surfaces of the extension plates 11 and the placement plate 603. Positioning rods 13 are inserted into the positioning holes 12. There are four sets of positioning rods 13, which are distributed on the surface of the placement plate 603 near the four corners. By inserting the positioning rods 13 into the positioning holes 12, the placement frame 7 can be further fixed after installation, preventing the placement frame 7 from falling off the placement plate 603 when the swing mechanism 6 is in use.

[0030] In this embodiment, magnetic absorbing pieces 15 are fixedly connected to the bottom of the positioning rod 13 and inside the positioning hole 12 located on the surface of the placement plate 603. The two sets of magnetic absorbing pieces 15 are matched in size. After the positioning rod 13 is inserted into the positioning hole 12, the two attract each other through the magnetic absorbing pieces 15, which ensures the stability of the positioning rod 13 after installation and prevents it from falling off during use.

[0031] In this embodiment, a rectangular piece is fixedly connected to the top of two adjacent sets of positioning rods 13, and a connecting strip 14 is fixedly connected to the side of the rectangular piece. A protrusion is fixedly connected to the surface of the connecting strip 14 near the edge. The two adjacent sets of positioning rods 13 are connected to each other by the connecting strip 14. Therefore, people only need to perform one operation to disassemble and assemble multiple sets of positioning rods 13, which reduces the time for people to disassemble and assemble.

[0032] In this embodiment, limit sockets 8 are provided on the lower sides of the drying chamber 1. A baffle 9 is hinged to the surface of the limit socket 8 via a damping hinge. A rubber sealing strip 10 is provided on the surface of the baffle 9. By providing a baffle 9 with a rubber sealing strip 10, when the baffle 9 is closed onto the limit socket 8, it will be embedded into its inner wall, thereby ensuring the sealing performance of the baffle 9 after it is closed, preventing heat loss in the drying chamber 1, and helping to improve the drying rate of subsequent vegetables.

[0033] In this embodiment, a pull handle is fixedly connected to the center of the surface of the placement frame 7. The surface of the pull handle has multiple sets of semi-circular grooves. By using the pull handle, people can easily pull the placement frame 7 out of the placement plate 603 and then pull it out of the limiting socket 8 to the outside of the equipment to retrieve vegetables.

[0034] In this embodiment, the surface of the door 2 is provided with an installation opening, and a transparent heat-insulating glass is embedded in the inner wall of the installation opening. Through the transparent heat-insulating glass, people can easily see the vegetable processing inside the drying box 1 from the outside.

[0035] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0036] In practical application, vegetables are placed in the placement frame 7, and then the placement frame 7 is inserted into the connecting block 16 through the mating groove 17 on its bottom connecting block 16. Pushing it forward quickly connects the placement frame 7 to the placement plate 603. Then, the positioning rod 13 is inserted through the extension plate 11 into the positioning hole 12 to further secure the placement frame 7. After completing these steps, the placement plate 603, driven by the cylinder 604, swings up and down with the rotation of the rotating shaft 602, thereby causing the vegetables in the placement frame 7 to move back and forth, adjusting the placement position of the vegetables. The movable section allows multiple sides of the vegetables to be exposed to hot air, eliminating the need for manual turning and improving the drying efficiency. After drying, the baffle 9 is opened, the positioning rod 13 is pulled out of the positioning hole 12, and then the pull handle is grasped to pull the placement frame 7 from the placement plate 603. It is then pulled out through the limiting socket 8 to the outside of the drying chamber 1 for retrieval. Because the opening of the limiting socket 8 is small, compared to directly opening the chamber door 2, it effectively reduces heat loss inside the drying chamber 1 when people are taking out or putting in vegetables, which helps to improve the drying rate of subsequent vegetables.

[0037] In summary, with the help of the above-mentioned technical solution of this utility model, the placement plate 603, driven by the cylinder 604, swings up and down with the rotation of the rotating shaft 602 through the swing mechanism 6, thereby driving the vegetables in the placement frame 7 to move back and forth, adjusting and moving the placement position of the vegetables so that multiple sides of the vegetables can be blown by hot air, eliminating the need for manual turning and helping to increase the effectiveness of the drying device. By inserting the placement frame 7 into the connecting block 16 through the docking groove 17 provided on the connecting block 16 and then pushing it forward, the placement frame 7 and the placement plate 603 can be quickly connected. Then, the positioning rod 13 is inserted into the positioning hole 12 to further fix the placement frame 7. Since the placement frame 7 is installed from the limiting insertion port 8, the opening of the drying box 1 is smaller when unloading materials. Compared with directly opening the box door 2, this effectively reduces the heat loss inside and helps to improve the drying rate of the vegetables.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
