Description

Technical Field

[0001] This invention relates to the field of morel mushroom screening technology, specifically to an automatic morel mushroom screening device. Background Technology

[0002] A morel mushroom screening device is used to remove dust from the surface of freshly picked morel mushrooms. It typically includes a motor, screen, outer casing, support frame, and controller. The device usually uses a motor to drive the screen to rotate, causing the material to continuously tumble on the screen for screening. Soil screening devices can be designed and adjusted according to different soil types and screening requirements; for example, different screens can be replaced or the screening time can be controlled.

[0003] Existing screening devices are generally simple cylindrical screens. The problem is that during screening, morel mushrooms tend to gather at the bottom of the screen, and it is not easy for multiple morel mushrooms to disperse. This causes some morel mushrooms to clump together, making it difficult to remove the soil on their surface. If the rotation speed of the screen is increased, the morel mushrooms will always stick to the inner wall of the screen under the action of centrifugal force, which greatly reduces the screening effect. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an automatic morel mushroom screening device to solve the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An automatic morel mushroom screening device includes a support base, and a screening component is disposed above the support base. The screening component includes:

[0009] The screen cylinder is rotatably connected to both sides of the support base. Under the drive of the rotary drive device, the screen cylinder rotates around the central axis of the screen cylinder.

[0010] Inner cylinder, which is rotatably connected to both sides of the support base;

[0011] A dispersing device is installed on the outer wall of the inner cylinder and is used to disperse the material inside the screen cylinder.

[0012] When the inner cylinder and the sieve cylinder rotate simultaneously, the morel mushrooms inside the sieve cylinder may be thrown onto the side wall of the sieve cylinder under the action of centrifugal force, and then fall onto the outer wall of the inner cylinder. When the morel mushrooms are thrown onto the outer wall of the inner cylinder, the soil on the surface of the morel mushrooms will be more easily separated, thereby achieving a better dispersing effect and improving the screening effect. Since a wide part and a narrow part are formed between the outer wall of the inner cylinder and the inner wall of the sieve cylinder, when the morel mushrooms approach the narrow part, they cannot pass through. At this time, the morel mushrooms fall off under the action of gravity, thus solving the problem of morel mushrooms sticking to the inner wall of the sieve cylinder in the existing technology.

[0013] Preferably, the inner cylinder is installed at an eccentric position inside the screen cylinder, and a wide section and a narrow section are formed between the outer wall of the inner cylinder and the inner wall of the screen cylinder, with a linear transition between the wide section and the narrow section.

[0014] Preferably, the dispersing device includes:

[0015] A dispersing rod, which is installed on the outer wall of the screen cylinder;

[0016] A cleaning rod is installed inside the screen cylinder, and both ends of the cleaning rod are connected to the inner side of the support base;

[0017] The protrusions are located at both ends of the cleaning rod. The cross-sectional shape of the protrusions is triangular. The protrusions can be used to scrape off the material on the cleaning rod.

[0018] Preferably, a vibrating block is placed inside the inner cylinder, and there are multiple vibrating blocks. One end of the inner cylinder is connected to a motor, which can drive the inner cylinder to rotate. When the inner cylinder rotates, the vibrating blocks inside it can also be driven to move, causing the vibrating blocks to collide back and forth inside the inner cylinder, thereby causing the inner cylinder to vibrate, so that dust is not easily adhered to the outer wall of the inner cylinder.

[0019] Preferably, the outer wall of the sieve cylinder has a slot, and a cover plate is installed in the slot. One end of the cover plate is hinged to one side of the slot, and the slot can be used to add or pour out morel mushrooms.

[0020] Preferably, a collection box is installed at the inner bottom of the support base. The collection box is used to collect the material that falls into the sieve cylinder. The inner bottom of the collection box is provided with an inclined surface, which is used to allow the material collected in the collection box to slide down.

[0021] Preferably, the dispersing device further includes:

[0022] A thin rod, the thin rod being connected to the end of the dispersing rod away from the inner cylinder;

[0023] The fine holes penetrate both ends of the dispersing rod, allowing the morel mushrooms to be dispersed.

[0024] Preferably, the dispersing device further includes:

[0025] A sleeve, the sleeve being connected to the inner wall of the inner cylinder, and one end of the sleeve communicating with the inner wall of the inner cylinder through a hole;

[0026] One end of the dispersing rod is slidably connected to the sleeve. The end of the dispersing rod located inside the sleeve has a limiting block, which causes the dispersing rod to be restricted inside the sleeve. When the dispersing rod rotates with the inner cylinder to the narrow part between the inner cylinder and the screen cylinder, under the action of gravity, the dispersing rod slides into the inside of the sleeve, which plays a role in storage and will not affect the rotation of the inner cylinder.

[0027] Preferably, one end of the screen cylinder is connected to a large gear, and one end of the inner cylinder is connected to a small gear. The small gear meshes with the large gear, so that the screen cylinder can rotate synchronously with the inner cylinder. However, since the small gear and the large gear have different specifications, the rotational speeds of the inner cylinder and the screen cylinder are different.

[0028] Preferably, an air pump is fixed to one end of the support base, and the air outlet of the air pump is connected to a first air pipe and a second air pipe. The first air pipe passes through the rotating shaft at one end of the inner cylinder and into the interior of the inner cylinder. A heater is connected to one end of the first air pipe. Brush bristles are connected to the inner wall of the collection box, and a gas collecting hood is connected to the outer wall of the collection box. One end of the second air pipe is connected to the gas collecting hood. The brush bristles are hollow with both ends open. The hollow part of the brush bristles communicates with the gas collecting hood, and one end of the brush bristles contacts the outer wall of the sieve cylinder.

[0029] Compared with the prior art, the present invention provides an automatic morel mushroom screening device, which has the following beneficial effects:

[0030] 1. This invention solves the problem in the prior art where morel mushrooms stick to the inner wall of the sieve cylinder when the inner cylinder and the sieve cylinder rotate simultaneously. Under the action of centrifugal force, morel mushrooms inside the sieve cylinder may be thrown onto the side wall of the sieve cylinder and then fall onto the outer wall of the inner cylinder. When the morel mushrooms are thrown onto the outer wall of the inner cylinder, the soil on the surface of the morel mushrooms is more easily separated, thereby achieving a better dispersion effect and improving the screening effect. Since a wide part and a narrow part are formed between the outer wall of the inner cylinder and the inner wall of the sieve cylinder, when the morel mushrooms approach the narrow part, they cannot pass through. At this time, the morel mushrooms fall off under the action of gravity, thus solving the problem of morel mushrooms sticking to the inner wall of the sieve cylinder in the prior art.

[0031] 2. When the vibrating block impacts inside the inner cylinder, the rigid connection between the inner cylinder and the screen cylinder means that when the inner cylinder vibrates, the screen cylinder can also vibrate to a certain extent, thereby improving the screening efficiency. Furthermore, the vibration also makes it less likely for the screen holes on the screen cylinder to become clogged.

[0032] 3. This invention starts the air pump, blows out air, and the air enters the inner cylinder as hot air through the first air pipe and the heater. This allows the inner cylinder to generate heat, which can dry the damp soil. At the same time, the gas can enter the sleeve, then enter the fine holes, and finally be sprayed out from the bottom of the dispersing rod, thereby blowing air onto the fine rod and cleaning the soil in the gaps between the fine rods.

[0033] 4. In this invention, air blown out by an air pump enters the interior of the air collection hood through the second air pipe. Then, the gas passes through the hollow part in the middle of the bristles and is finally blown toward the screen cylinder to clean the dust on the surface of the screen cylinder. Since the ends of the bristles abut against the surface of the screen cylinder, the dust on the surface of the screen cylinder can be brushed away. Attached Figure Description

Detailed Implementation

[0043] Example:

[0044] See Figure 1-2This embodiment discloses an automatic morel mushroom screening device, including a support base 100, and a screening component 200 disposed above the support base 100. The screening component 200 includes:

[0045] The sieve cylinder 210 is rotatably connected to both sides of the support base 100. Under the drive of the rotary drive device, the sieve cylinder 210 rotates about the central axis of the sieve cylinder 210.

[0046] Inner cylinder 220, which is rotatably connected to both sides of support base 100;

[0047] Dispersing device 300, which is installed on the outer wall of inner cylinder 220, is used to disperse the material in screen cylinder 210;

[0048] The dispersing device 300 can separate multiple morel mushrooms, thus achieving a better screening effect.

[0049] like Figure 2 As shown, in one possible embodiment, the inner cylinder 220 can be installed at an eccentric position inside the sieve cylinder 210, and a wide portion and a narrow portion are formed between the outer wall of the inner cylinder 220 and the inner wall of the sieve cylinder 210, and the wide portion and the narrow portion are linearly transitioned.

[0050] With the above scheme, when the inner cylinder 220 and the sieve cylinder 210 rotate at the same time, under the action of centrifugal force, the morel mushrooms in the sieve cylinder 210 may be thrown onto the side wall of the sieve cylinder 210 and then fall onto the outer wall of the inner cylinder 220. When the morel mushrooms are thrown onto the outer wall of the inner cylinder 220, the soil on the surface of the morel mushrooms will be more easily separated, thereby achieving a better dispersing effect and improving the screening effect.

[0051] Because a wide section and a narrow section are formed between the outer wall of the inner cylinder 220 and the inner wall of the sieve cylinder 210, when morel mushrooms approach the narrow section, they cannot pass through. At this time, the morel mushrooms fall off under the action of gravity, thus solving the problem of morel mushrooms sticking to the inner wall of the sieve cylinder in the prior art.

[0052] Continue reading Figure 3 The dispersing device 300 specifically includes:

[0053] Dispersing rod 310, the dispersing rod 310 is installed on the outer wall of screen cylinder 210;

[0054] Cleaning rod 350 is installed inside the screen cylinder 210, and both ends of the cleaning rod 350 are connected to the inner side of the support base 100;

[0055] The protrusions 360 are provided at both ends of the cleaning rod 350. The cross-sectional shape of the protrusions 360 is triangular. The material on the dispersing rod 310 can be scraped off through the protrusions 360.

[0056] Since the surface of the morel mushrooms will be covered with dust when the dispersing rod 310 is dispersing them, the dust can be scraped off by the cleaning rod 350 and the protrusion 360.

[0057] like Figure 2 , Figure 4 As shown, a vibrating block 230 is placed inside the inner cylinder 220. There are multiple vibrating blocks 230. One end of the inner cylinder 220 is connected to a motor 240. The motor 240 can drive the inner cylinder 220 to rotate. When the inner cylinder 220 rotates, the vibrating blocks 230 inside it can also be driven, causing the vibrating blocks 230 to hit back and forth inside the inner cylinder 220, thereby causing the inner cylinder 220 to vibrate. As a result, dust is less likely to adhere to the outer wall of the inner cylinder 220.

[0058] When the vibrating block 230 impacts inside the inner cylinder 220, since there is a rigid connection between the inner cylinder 220 and the screen cylinder 210, the screen cylinder 210 can also vibrate to a certain extent when the inner cylinder 220 vibrates, thereby improving the screening efficiency. Furthermore, the vibration also makes it less likely for the screen holes on the screen cylinder 210 to become clogged.

[0059] Continue reading Figure 5 The outer wall of the sieve cylinder 210 is provided with a slot 211, and a cover plate 212 is installed in the slot 211. One end of the cover plate 212 is hinged to one side of the slot 211 by a hinge. The slot 211 can be used to add or pour out morel mushrooms.

[0060] Of course, when the cover plate 212 is closed, it can be locked to the slot 211 by a limiting device such as a bayonet, so that the cover plate 212 will not be popped open when the screen cylinder 210 rotates.

[0061] like Figure 2 As shown, a collection box 110 is installed at the inner bottom of the support base 100. The collection box 110 is used to collect the material that falls into the sieve cylinder 210. An inclined surface 120 is provided at the inner bottom of the collection box 110. The inclined surface 120 is used to allow the material collected in the collection box 110 to slide down.

[0062] like Figure 2-3 As shown, in one possible embodiment, the dispersing device 300 further includes:

[0063] Thin rod 320, the thin rod 320 being connected to the end of the dispersing rod 310 away from the inner cylinder 220;

[0064] Fine holes 330 penetrate the upper and lower ends of the dispersing rod 310. The fine rod 320 can be used to disperse morel mushrooms.

[0065] Sleeve 340, the sleeve 340 is connected to the inner wall of the inner cylinder 220, and one end of the sleeve 340 is also connected to the inner wall of the inner cylinder 220 through a hole;

[0066] One end of the dispersing rod 310 is slidably connected to the sleeve 340. The end of the dispersing rod 310 located inside the sleeve 340 has a limiting block, which causes the dispersing rod 310 to be restricted inside the sleeve 340. When the dispersing rod 310 rotates with the inner cylinder 220 to the narrow part between the inner cylinder 220 and the sieve cylinder 210, under the action of gravity, the dispersing rod 310 slides into the inside of the sleeve 340, which plays a role in storage and will not affect the rotation of the inner cylinder 220.

[0067] Continue reading Figure 6 In one possible embodiment, a large gear 260 is connected to one end of the sieve cylinder 210, and a small gear 250 is connected to one end of the inner cylinder 220. The small gear 250 meshes with the large gear 260, so that the sieve cylinder 210 can rotate synchronously with the inner cylinder 220. However, since the specifications of the small gear 250 and the large gear 260 are different, the rotational speeds of the inner cylinder 220 and the sieve cylinder 210 are different.

[0068] Continue reading Figure 7-8 In one possible embodiment, an air pump 410 is fixed to one end of the support base 100. The air outlet of the air pump 410 is connected to a first air pipe 420 and a second air pipe 440. The first air pipe 420 passes through the rotating shaft at one end of the inner cylinder 220 and into the interior of the inner cylinder 220. A heater 460 is connected to one end of the first air pipe 420. Brush bristles 450 are connected to the inner wall of the collection box 110. A gas collecting hood 430 is connected to the outer wall of the collection box 110. One end of the second air pipe 440 is connected to the gas collecting hood 430. The brush bristles 450 are hollow designs with both ends through. The hollow part of the brush bristles 450 communicates with the gas collecting hood 430. One end of the brush bristles 450 is in contact with the outer wall of the sieve cylinder 210.

[0069] With the above scheme, the air pump 410 is started, blowing out air. The air enters the inner cylinder 220 as hot air from the first air pipe 420 and passes through the heater 460, thereby generating heat in the inner cylinder 220. The heat can dry the damp soil. At the same time, the gas can enter the sleeve 340, then enter the fine hole 330, and finally be sprayed out from the bottom end of the dispersing rod 310, thereby blowing air into the fine rod 320 and cleaning the soil in the gap between the fine rods 320.

[0070] Air enters the interior of the air collection hood 430 through the second air pipe 440, and then the gas passes through the hollow part in the middle of the bristles 450 and is finally blown toward the screen cylinder 210 to clean the dust on the surface of the screen cylinder 210. Since the ends of the bristles 450 abut against the surface of the screen cylinder 210, the dust on the surface of the screen cylinder 210 can be brushed away.
