Description

Technical Field

[0003] In the process of preparing microbial organic fertilizer, it is necessary to turn the pile in time according to the change of pile temperature and fermentation progress. Turning the pile can provide oxygen and accelerate the fermentation process of microorganisms; at the same time, it can regulate the pile temperature and prevent overheating from causing the death of microorganisms.

[0004] When turning the compost of fermented fertilizer, it is necessary to use a compost turning device.

However, during use, the existing microbial organic fertilizer preparation compost turning device cannot turn the fertilizer in the corners of the compost trough, resulting in that some fertilizers cannot be turned after the compost fermentation process is completed. This makes it easy for some waste materials to be unable to ferment normally, thereby affecting the fermentation quality of the fertilizer. Moreover, the existing compost turning device can only turn the bottom, but cannot turn the fertilizer on both sides of the upper part, which will result in that the fertilizer on both sides cannot be fully turned, thereby affecting the fermentation efficiency, and at the same time, the fertilizer cannot be fully turned to improve the fermentation quality.

An extrusion sleeve 125 is fixedly connected to one end of the cylinder 126, and limiting holes 123 are symmetrically provided on the outer surfaces of the two end edges of the transverse support frame 127.

[0021] The fermentation component 2 includes a fermentation feed trough 24, which has first tooth grooves 23 on both sides of the top, and limiting columns 21 on both sides of the inner top of the fermentation feed trough 24. An electric control box 25 is fixedly installed on the side of one end of the fermentation feed trough 24, and a transmission sprocket shaft 27 is fixedly connected to one end of the driving motor 26.

[0022] The transverse support frame 127 of the present invention is slidably connected to the outer surface of the limiting column 21 through the socket hole 121. The outer surface of the limiting column 21 is provided with a second tooth groove. The transmission shaft 14 is meshed and connected with the second transmission chain 22 through the second sprocket 13. The first sprocket 113 is rotatably connected with the third sprocket 15 through the first transmission chain 112, so that when the transverse support frame 127 moves, it can drive the transverse stirring shaft 117 to turn the fertilizer inside the fermentation feed tank 24.

[0023] The vertical scraper 118 and the corner scraper 116 of the present invention are in close contact with the inner surface of the fermentation feed trough 24, and can scrape off the fertilizer in the corners of the surface of the fermentation feed trough 24.

The top end of the vertical stirring shaft 119 is fixedly connected with a second transmission gear inside the limiting sleeve 120.

[0024] The vertical stirring shaft 119 of the present invention is meshed and connected with the second tooth groove on the outer surface of the limiting column 21 inside the limiting sleeve 120 through the second transmission gear at the top. Therefore, when the vertical stirring shaft 119 slides horizontally, it will be driven to rotate to stir the fertilizer on both sides of the fermentation feed trough 24. The limiting rod 17 is slidably connected with the horizontal support frame 127 through the limiting socket 123, which can play a limiting role in the lifting and lowering of the V-shaped scraper 18.

[0025] The extrusion sleeve 125 of the present invention is slidably sleeved on the outer surface of the transmission shaft 14 and abutted against the clamping plate 03, which can control the up and down flipping of the clamping plate 03, thereby controlling the connection between the clamping plate 04 and the transmission shaft 14. A clamping groove is provided on the inner surface of the clamping plate 04, and the two ends of the transmission shaft 14 are rotatably clamped with the upper side of the protective cover 122. The limit plate 124 abuts against the two sides of the clamping plate 04, which can limit the rotation of the clamping plate 04.

[0026] The transmission shaft 14 of the present invention is meshed and connected with the first tooth groove 23 through the first transmission gears 16 at both ends, and can drive the lateral support frame 127 to move inside the fermentation feed tank 24 when the transmission shaft 14 rotates. The second transmission chain 22 is interlaced and connected with the protective cover 122, and can limit the second transmission chain 22 to the top of the protective cover 122 to prevent the second transmission chain 22 from separating from the second sprocket 13. The limiting frame 111 contacts the inner bottom surface of the fermentation feed tank 24 through the roller 114 at the bottom, and can ensure that the corner scraper 116 slides in the inner bottom end process of the fermentation feed tank 24. The gear ratio of the third sprocket 15 to the first sprocket 113 is three to one, so the rotation speed of the first sprocket 113 is three times that of the third sprocket 15, so that the fertilizer inside the fermentation feed tank 24 can be quickly turned over.

[0027] The working principle of the present invention is as follows: when it is necessary to prepare microbial organic fertilizer, the raw materials for preparing the fertilizer are first mixed and poured into the fermentation feed tank 24 for fermentation. When it is necessary to turn the compost, the turning and mixing component 1 is at the end of the fermentation feed tank 24, and then the electric control box 25 is started to control the operation of the drive motor 26, so that the drive motor 26 drives the second transmission chain 22 meshingly connected at both ends of the outer surface to rotate through the transmission sprocket shaft 27 at one end. When the second transmission chain 22 rotates, it will drive the second sprocket 13 meshingly connected on the inner surface to rotate. When the second sprocket 13 rotates, it will drive the transmission shaft 14 to rotate synchronously, so the rotation of the transmission shaft 14 will move on the upper surface of the first tooth groove 23 through the first transmission gears 16 at both ends, and at the same time, the transmission shaft 14 will The third sprocket 15 and the first transmission chain 112 on the outer surfaces of both ends drive the first sprocket 113 to rotate synchronously. When the first sprocket 113 rotates, it will drive the horizontal stirring shaft 117 connected to the side to rotate synchronously. When the horizontal stirring shaft 117 rotates, the fermented fertilizer inside the fermentation feed tank 24 will be turned over, so as to achieve the purpose of turning the fertilizer, and when the transmission shaft 14 moves, it will drive the horizontal support frame 127 to move synchronously inside the fermentation feed tank 24. When the horizontal support frame 127 moves, it will drive the protective cover 122 and the limiting frame 111 to move synchronously. When the protective cover 122 moves, it will drive the vertical scrapers 118 on both sides to move, so that the vertical scrapers 118 scrape off the fertilizer adhered to the inner surface of the fermentation feed tank 24, and the limiting frame 111 The positioning frame 111 will drive the corner scraper 116 at one end to scrape the fertilizer in the corners inside the fermentation feed trough 24, so as to prevent the fertilizer from adhering to the inner surface of the fermentation feed trough 24 for a long time and affecting the quality of the fermentation fertilizer preparation. In addition, when the horizontal support frame 127 moves, the vertical stirring shaft 119 will be driven to move synchronously through the limiting sleeve 120. Therefore, when the second transmission gear at the top of the vertical stirring shaft 119 is engaged with the second tooth groove on the outer surface of the limiting column 21, the movement of the horizontal support frame 127 will drive the vertical stirring shaft 119 to rotate synchronously, thereby stirring the fermented fertilizer on both sides of the fermentation feed trough 24. Therefore, the horizontal stirring shaft 117 and the vertical stirring shaft 119 rotate in coordination, so as to fully turn over the fertilizer inside the fermentation feed trough 24 and adjust the vertical stirring shaft 119. The compost temperature is adjusted, and when the lateral support frame 127 moves, it will drive the V-shaped scraper 18 to move synchronously through the limit rod 17, so as to scrape the compost on the top of the fermentation feed trough 24, so that the compost can be evenly composted and fermented to avoid excessive temperature differences. Moreover, when the compost at different heights is turned over, it is necessary to adjust the height of the V-shaped scraper 18. When adjusting the height of the V-shaped scraper 18, the cylinder 126 can be controlled to drive the clamping plate 03 at one end to slide close to the clamping plate 04, thereby squeezing the clamping plate 03 to contract inside 10, so that the clamping plate 03 is separated from the clamping groove inside the clamping plate 04, so that the V-shaped scraper 18 descends under the action of gravity, and at the same time, the connecting rope 190 drives the clamping plate 04 to unwind and rotate. When the V-shaped scraper 18 descends to a suitable height,The cylinder 126 can be controlled to drive the extrusion sleeve 125 at one end to slide away from the clamping plate 04, so that the clamping plate 03 is squeezed by the tensioning spring 02 until the clamping plate 03 is aligned with the clamping groove on the inner surface of the clamping plate 04, so that the clamping plate 03 is flipped upward and reset, thereby positioning the position of the V-shaped scraper 18 after it is lowered. When the height of the V-shaped scraper 18 needs to be raised, when the clamping plate 03 is clamped with the inner surface of the clamping plate 04, the transmission shaft 14 can be controlled to drive the clamping plate 04 to rotate, so that the clamping plate 04 reels the connecting rope 190, thereby bringing The V-shaped scraper 18 moves upward, so only when the bottom of the V-shaped scraper 18 contacts the fermented fertilizer inside the fermentation feed tank 24, it is necessary to squeeze the clamping plate 03 and separate the inside of the clamping plate 04, and then when the transmission shaft 14 rotates, it will not drive the clamping plate 04 to rotate, thereby ensuring the height of the V-shaped scraper 18. Therefore, under the coordinated operation of the stirring component 1 and the fermentation component 2, the microbial organic fermented fertilizer can be fully turned over to adjust the temperature, and the marginal fertilizer inside the fermentation tank can be turned over and removed to avoid some fertilizers from being unable to ferment normally and affecting the fermentation quality.
