DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be described further in detail below in conjunction with the drawings. Only this declaration, the up, down, left, right, front, back, inside, outside and other orientation words appearing or about to appear in the text of the utility model, only take the drawings of the utility model as the base, it is not the specific limitation to the utility model.

[0024] As Figures 1-5As shown, a seedling substrate screening device, including a fixed frame 1, a first support frame 2, a second support frame 13 and a screening mechanism 5, the fixed frame 1 is a rectangular frame structure, and the upper part of the fixed frame 1 is symmetrically provided with the first support frame 2 and the second support frame 14, and the inside of the first support frame 2 and the second support frame 14 is provided with the screening mechanism 5; the screening mechanism 5 includes a screening groove 501, a screening net 509, a rotating shaft 508, a support 503, an auxiliary wheel 504, an eccentric wheel 505 and a pressure spring 502, the screening groove 501 is a rectangular cavity structure with an open upper part, and the inside of the screening groove 501 is provided with the screening net 509, the two sides of the screening groove 501 are movably connected with the through hole on the connecting block of the first support frame 2 through connecting rods, and the pressure spring 502 is arranged on the outer wall of the connecting rod to form an elastic structure; the two sides of the screening groove 501 are provided with the support 503, and the auxiliary wheel 504 in the support 503 is arranged in connection with the eccentric wheel 505 on the rotating shaft 508; the rotating shaft 508 is arranged on the fixed frame 1 through a second bearing seat 506, and one end of the rotating shaft 508 is connected with the crushing mechanism 3.

[0025] It should be noted that the substrate is one of the important materials for cultivating dendrobium candidum, and in the early stage, different substrates need to be crushed and screened, and then mixed into the required substrate material. In this process, the traditional process is generally divided into two parts of crushing and screening, which needs to be crushed first and then screened. The whole process is transported by a conveying mechanism. This kind of transport structure, crushing structure and screening structure need a larger working site. Therefore, we integrate the three processes into one, which can realize crushing, screening and transportation at the same time, thereby improving the efficiency.

[0026] It should be further pointed out that in order to crush different materials at the same time, the first support frame 2 and the second support frame 14 are arranged on the fixed frame 1, and the crushing mechanism 3 is arranged on the two support frames respectively, so that two kinds of materials can be crushed at the same time. Moreover, the screening mechanism 5 is arranged at the lower part of the crushing mechanism 3, which realizes real-time screening during the crushing process and realizes the integration of crushing and screening.

[0027] It needs to be further explained that when the screening mechanism 5 is running, the rotating shaft 508 starts to rotate, and then drives the eccentric wheel 505 to rotate. At this time, the eccentric wheel 505 is closely connected with the outer wall of the auxiliary wheel 504 on one side of the screening groove 501. Under the action of the continuous rotation of the eccentric wheel 505, the screening groove 501 will be repeatedly lifted and lowered, so as to realize the function of vibrating screening. The screening groove 501 is movably connected with the through hole on the connecting block of the first support frame 2 through the connecting rods on both sides of the screening groove 501. The pressure spring 502 is arranged on the outer wall of the connecting rod, so as to form an elastic structure. This elastic structure not only can work cooperatively with the eccentric wheel 505, but also can ensure that the auxiliary wheel 504 and the eccentric wheel 505 always maintain the state of close contact, so as to ensure the stable and efficient operation of the whole screening process.

[0028] It needs to be particularly pointed out that if the auxiliary wheel 504 and the eccentric wheel 505 cannot maintain the close contact, the transmission may be interrupted or unstable. The pressure spring 502 is arranged on the connecting rod through the elastic force of the pressure spring 502, so that the auxiliary wheel 504 always has the tendency to approach the eccentric wheel 505, thereby ensuring the stable transmission of power and maintaining the continuity of the screening action.

[0029] As shown in Figures 2-5 The crushing mechanism 3 includes a crushing chamber 301, a first crushing roller 302, a second crushing roller 309, a first gear 303, a second gear 304, a fixed plate 305, a driving motor 306 and a synchronous belt 310.

One end of the first crushing roller 302 and the second crushing roller 309 is connected with the first gear 303 and the second gear 304 respectively, and the first gear 303 and the second gear 304 are meshed and connected. The fixed plate 305 is arranged on one side of the crushing chamber 301, and the driving motor 306 is arranged on the fixed plate 305. The output shaft of the driving motor 306 is connected with the rotating shaft of the first crushing roller 302 through a shaft coupling. The rotating shaft is provided with a first synchronous wheel, and the first synchronous wheel is connected with the second synchronous wheel 308 on the two rotating shafts 508 through the synchronous belt 310. The fixed plate 305 is provided with a first bearing seat 307, and the first bearing seat 307 is connected with the rotating shaft 508.

[0030] It needs to be pointed out that the first crushing roller 302 and the second crushing roller 309 are arranged in the crushing chamber 301, and are connected with the first gear 303 and the second gear 304 respectively. The first gear 303 and the second gear 304 are meshed and arranged, forming a transmission structure. The driving motor 306 drives the first gear 303 to rotate, which can simultaneously drive the first crushing roller 302 and the second crushing roller 309, so as to complete the crushing.

[0031] It needs to be further explained that in order to realize the transmission of power, we set the first synchronous wheel at the rotating shaft of the first crushing roller 302, and the first synchronous wheel is connected with the second synchronous wheel 308 on the two rotating shafts 508 through the synchronous belt 310, so as to transmit power to the rotating shaft 508 and complete the vibration process.

[0032] As shown in Figures 1-5 The inside of the first support frame 2 is provided with the first conveying table 11, and the first conveying table 11 is located at the lower part of the screening groove 501, and one end of the first conveying table 11 is connected with the material collecting groove 9 through the second conveying table 7; the inside of the material collecting groove 9 is provided with the feeding support 6, and the inside of the feeding support 6 is provided with the conveying belt 10, and the conveying belt 10 is provided with the lifting baffle; the upper part of the screening groove 501 is provided with the sealing cover 12, and the sealing cover 12 is provided with the feeding port 13.
