Technical Field
[0001] This utility model relates to the field of greenhouse ventilation technology, specifically a ventilation device for edible mushroom greenhouses. Background Technology
[0002] Edible fungi refer to a class of large fungi that can form large fleshy, gelatinous fruiting bodies or sclerotia-like tissues, and can be used for human consumption or medicinal purposes. In order to increase the yield of edible fungi, people often carry out artificial cultivation of edible fungi in edible fungi greenhouses.
[0003] When cultivating edible fungi, it is necessary to use fans to continuously draw air into the greenhouse through ventilation ducts in order to provide sufficient oxygen for the growth of edible fungi. However, traditional air supply devices cannot effectively diffuse the air into the greenhouse. Furthermore, when the heater inside the air supply device is damaged, it is not convenient to disassemble it for replacement or maintenance. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an air supply device for edible mushroom greenhouses, which solves the problems mentioned in the background art that traditional air supply devices cannot effectively diffuse the supplied air to the surrounding areas of the greenhouse, and that it is inconvenient to disassemble and replace or maintain the heater inside the air supply device when it is damaged.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a ventilation device for edible mushroom greenhouses, comprising a heating box, an installation groove on one side end face of the heating box, four positioning columns arranged in a circumferential array fixedly installed in the installation groove, threaded grooves in the positioning columns, an installation plate disposed in the installation groove, a heater fixedly installed on the inner end surface of the installation plate, four positioning holes arranged in a circumferential array on the installation plate, an air outlet pipe fixedly installed on the front end surface of the heating box, an air outlet hopper threadedly mounted on the front end surface of the air outlet pipe, the air outlet hopper being conical in shape, and multiple staggered guide plates fixedly installed inside the heating box.
[0006] Using the above technical solution, the heated air moves through multiple guide plates inside the heating box towards the air outlet duct, and is finally discharged through the air outlet duct. Because the air outlet duct is cone-shaped, it can effectively diffuse the air to all sides of the greenhouse. Since the heater is mounted on the mounting plate, workers can remove the threads in the positioning column to remove the restriction of the mounting plate, and then remove the heater for easy maintenance. Because the guide plates are made of hemp fibers, when there are water droplets in the air, the hemp fibers on the guide plates will absorb the water droplets, thus preventing the air entering the greenhouse from becoming damp.
[0007] Preferably, a connecting pipe is fixedly installed on the rear surface of the heating box, an air inlet pipe is fixedly installed at the end of the connecting pipe, and a guide fan is installed inside the air inlet pipe.
[0008] Using the above technical solution, the filtered air can be effectively delivered into the heating box for heating through the connecting pipe, and then the guide fan can easily guide the air into the air supply device.
[0009] Preferably, the end of the air inlet pipe is threadedly mounted with a fixing bracket, and handles are fixedly mounted on both ends of the fixing bracket. A first filter screen is fixedly mounted on the outer end surface of the fixing bracket, and two fixing plates are fixedly mounted on the inner end surface of the fixing bracket. A second filter screen is fixedly mounted on the bottom of the fixing plates.
[0010] Using the above technical solution, the first filter can filter out some larger particulate impurities in the air. Then, because there is a second filter directly in front of the first filter, the air that has been initially filtered will undergo secondary filtration through the second filter to remove some smaller impurities, thus preventing impurities from entering the greenhouse. When it is necessary to clean the first and second filters, since the fixing frame and the air inlet pipe are connected by threads, the workers can rotate the fixing frame using the handles installed at both ends of the fixing frame to remove the fixing frame from the air inlet pipe, making it easy for workers to clean the first and second filters inside the fixing frame.
[0011] Preferably, the surfaces of the multiple guide plates inside the heating box are all provided with hemp fibers.
[0012] By adopting the above technical solution, the guide plate is made of hemp fiber, which absorbs water droplets in the air when they are present, thus preventing the air entering the greenhouse from becoming damp.
[0013] Preferably, the second filter screen installed on the fixed plate is located at the front end of the first filter screen.
[0014] By adopting the above technical solution, a second filter screen is set in front of the first filter screen. Therefore, the air that has been initially filtered will be filtered again by the second filter screen, thereby filtering out some smaller impurities in the air and preventing impurities in the air from entering the greenhouse.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. The mushroom greenhouse uses an air supply device. Heated air is guided through multiple guide plates in the heating box towards the air outlet pipe, and finally discharged through the air outlet duct. Because the air outlet duct is cone-shaped, it can effectively diffuse the air to all sides of the greenhouse. Since the heater is mounted on the mounting plate, the operator can remove the threads in the positioning column to remove the mounting plate's restriction, and then remove the heater for easy maintenance. Because the guide plates are made of hemp fiber, when there are water droplets in the air, the hemp fiber on the guide plates will absorb the water droplets, thus preventing the air entering the greenhouse from becoming damp.
[0017] 2. The ventilation system in this mushroom greenhouse uses a first filter to filter larger particulate impurities from the air. A second filter, located directly in front of the first filter, further filters the air, removing smaller impurities and preventing them from entering the greenhouse. When cleaning the first and second filters, the fixed frame and air inlet pipe are threaded together. Workers use handles at both ends of the fixed frame to rotate it, detaching it from the air inlet pipe for easy cleaning of the first and second filters. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0024] Example 1:
[0025] Please refer to the following: Figure 1-4 A ventilation device for edible mushroom greenhouses includes a heating box 1 with an installation groove 2 on one side end face. Four positioning posts 3 arranged in a circular array are fixedly installed in the installation groove 2. Each positioning post 3 has a threaded groove. An installation plate 17 is installed in the installation groove 2. A heater 4 is fixedly installed on the inner end surface of the installation plate 17. Four positioning holes 5 arranged in a circular array are opened on the installation plate 17. An air outlet pipe 6 is fixedly installed on the front end surface of the heating box 1. An air outlet hopper 7 is threadedly and rotatably installed on the front end surface of the air outlet pipe 6. The air outlet hopper 7 is conical in shape. Multiple guide plates 8 arranged in an alternating pattern are fixedly installed inside the heating box 1. The surfaces of the multiple guide plates 8 inside the heating box 1 are all covered with hemp fibers.
[0026] Working principle: After the air supplied to the greenhouse is filtered by the first filter 14 and the second filter 16, the temperature of the heater 4 is adjusted to match the temperature inside the greenhouse. The filtered air then enters the heating chamber 1 through the connecting pipe 9. After passing through the heating chamber 1, the air is heated by the heater 4. The heated air then moves through multiple guide plates 8 inside the heating chamber 1 towards the air outlet duct 6, and finally exits through the air outlet duct 7. Because the air outlet duct 7 is cone-shaped, it effectively... This allows the air to diffuse around the greenhouse. Since the heater 4 is installed on the mounting plate 17, the staff can remove the threads inside the positioning column 3 to remove the restriction of the mounting plate 17. Once the restriction of the mounting plate 17 is removed, it is easy for the staff to remove the heater 4 for subsequent maintenance. Because the guide plate 8 is made of hemp fiber, when there are water droplets in the air, the hemp fiber on the guide plate 8 will absorb the water droplets in the air, thereby preventing the air entering the greenhouse from becoming damp. Moreover, the hemp fiber also has good high temperature resistance.
[0027] Example 2:
[0028] Please refer to the following: Figure 1-4 A ventilation device for edible mushroom greenhouses includes a connecting pipe 9 fixedly installed on the rear surface of the heating box 1, an air inlet pipe 10 fixedly installed at the end of the connecting pipe 9, a guide fan 11 installed inside the air inlet pipe 10, a fixing frame 12 threadedly installed at the end of the air inlet pipe 10, handles 13 fixedly installed on both ends of the fixing frame 12, a first filter screen 14 fixedly installed on the outer surface of the fixing frame 12, two fixing plates 15 fixedly installed on the inner surface of the fixing frame 12, a second filter screen 16 fixedly installed at the bottom of the fixing plate 15, and the second filter screen 16 installed on the fixing plate 15 is located at the front end of the first filter screen 14.
[0029] Working principle: When the guide fan 11 is turned on, it guides the outside air into the air inlet duct 10. Because the air inlet end of the air inlet duct 10 is equipped with a fixing frame 12 and a first filter screen 14 is installed on the fixing frame 12, the first filter screen 14 can filter some larger particulate impurities in the air before the air enters the air inlet duct 10. Then, because a second filter screen 16 is installed in front of the first filter screen 14, the air after the initial filtration will pass through the second filter screen 16 for secondary filtration, thereby filtering out some smaller impurities in the air and preventing impurities in the air from entering the greenhouse. When it is necessary to clean the first filter screen 14 and the second filter screen 16, because the fixing frame 12 and the air inlet duct 10 are connected by threads, the staff can rotate the fixing frame 12 by using the handles 13 installed at both ends of the fixing frame 12, thereby removing the fixing frame 12 from the air inlet duct 10, so that the staff can clean the first filter screen 14 and the second filter screen 16 inside the fixing frame 12.
