Abstract
Description
Technical Field
[0001] This utility model relates to the field of straw crushing technology, specifically to an integrated crushing and mixing machine for straw yeast fermentation feed. Background Technology
[0002] Straw typically refers to the residue left after harvesting wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane, and other crops (usually coarse grains). More than half of the products of crop photosynthesis are found in straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium, and organic matter, making it a versatile and renewable biological resource. Usually, after harvesting, the straw is crushed using crushing equipment, and then yeast is mixed with the crushed straw using a mixing device.
[0003] When crushing straw, the straw is crushed in one pass by the crushing roller. Although the crushing is relatively thorough, a small portion of the straw will still not be crushed properly. This will cause large pieces of material to decompose slowly during the subsequent fermentation process, affecting fermentation efficiency and feed quality. Secondly, when screening the crushed straw, the screen is usually stationary. This can easily cause the screen to be blocked by straw, affecting the continuous screening of straw. Utility Model Content

Detailed Implementation
[0021] 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.
[0022] Example: Figure 1-7 As shown, this utility model provides a crushing and mixing machine for fermented feed made from straw and yeast, including a crushing mechanism 1, a screening mechanism 2 below the crushing mechanism 1, a mixing mechanism 3 below the screening mechanism 2, and a conveying mechanism 4 on the left side of the crushing mechanism 1.
[0023] The crushing mechanism 1 has two symmetrically distributed crushing rollers 12 rotatably mounted inside, and gears 13 are fixedly mounted on the outside of each of the two crushing rollers 12, and the two gears 13 mesh with each other;
[0024] The screening mechanism 2 includes a screening box 21, a semi-circular screen 22 inside the screening box 21, a discharge port 23 on the side of the screening box 21 near the conveying mechanism 4, a feed port through the top of the screening box 21, and a shaking mechanism 5 at the bottom of the screen 22.
[0025] The conveying mechanism 4 includes an inclined outer shell 41. A rotating shaft 42 rotatably passes through both the upper and lower ends of the outer shell 41. A belt 43 is fitted around the outside of the rotating shaft 42 via conveying rollers. Several equally spaced scrapers 44 are fixedly installed on the outside of the belt 43. The outer wall of the scrapers 44 is in contact with the inner wall of the outer shell 41, and the side of the scrapers 44 away from the belt 43 is arc-shaped. The upper and lower ends of the outer shell 41 are also arc-shaped. An inclined feeding plate 45 and an inclined discharge plate 46 are fixedly installed on the side of the outer shell 41 closest to the crushing box 11. The feeding plate 45 is located above the discharge plate 46. Both the feeding plate 45 and the discharge plate 46 are U-shaped, discharging material... Plate 46 is fixedly connected to screening box 21. The upper rotating shaft 42 is connected to the left crushing roller 12 via synchronous belt drive. Crushing roller 12 is driven by motor 1 and is fixedly connected to right crushing roller 12. Motor 1 and gear 13 are opposite to each other. Crushing mechanism 1 is slightly close to the right edge of screening mechanism 2. Synchronous belt drive can be toothed synchronous belt drive or chain and sprocket drive. Stirring mechanism 3 achieves stirring by cooperating with stirring blades through stirring shaft. The stirring container is stirring tank. The outer shell 41 is supported by two symmetrically distributed support plates. Screening box 21 is also supported by two symmetrically distributed support plates.
[0026] The shaking mechanism 5 includes two symmetrically distributed connecting blocks 51 with different heights. Guide rods 52 are fixedly installed at the bottom of each connecting block 51. A fixed plate 53 is slidably sleeved on the outside of the guide rods 52. The fixed plate 53 is fixedly connected to the inner wall of the screening box 21. A movable plate 54 is fixedly installed at the bottom of the guide rods 52. A rotating shaft 56 passes through the bottom of the screening box 21. An elliptical wheel 57 that fits against the movable plate 54 is fixedly installed on the outside of the rotating shaft 56. The rotating shaft 56 is driven by a motor, and the motor is opposite to the conveying mechanism 4. By setting the shaking mechanism 5, the screen 22 shakes up and down, preventing the crushed straw from clogging the screen 22 and affecting the screening of the straw.
[0027] A spring 55 is fixedly installed between the fixed plate 53 and the movable plate 54. The spring 55 is located outside the guide rod 52. By setting the spring 55, the vibration of the spring 55 increases the vibration frequency of the screen 22, thereby improving the efficiency of straw screening.
[0028] The spring 55 is provided with a telescopic rubber sleeve 58. The top end of the telescopic rubber sleeve 58 is fixedly connected to the fixed plate 53, and the bottom end of the telescopic rubber sleeve 58 is fixedly connected to the movable plate 54. By setting the telescopic rubber sleeve 58, the spring 55 is protected to prevent dust from falling directly into the spring 55 and affecting the elasticity of the spring 55.
[0029] A semi-circular block 59 is fixedly installed at the end of the screen 22 away from the discharge port 23. By setting the semi-circular block 59, straw that falls onto the screen 22 is prevented. Under shaking, the straw falls directly from the screening box 21 into the mixing bucket of the mixing mechanism 3 without being screened.
[0030] The screen 22 is inclined, and the end near the discharge port 23 is an inclined conical hopper, so that the crushed straw can be quickly discharged from the discharge port 23 into the outer shell 41.
[0031] Two symmetrically distributed inclined plates 6 are fixedly installed on the lower inner wall of the screening box 21. The inclined plates 6 are located at the feed inlet and form a cross shape with the crushing roller 12. By setting the inclined plates 6, the crushed straw is prevented from falling directly from both sides of the screen 22 into the mixing tank of the mixing mechanism 3.
[0032] A support block 7 is fixedly installed on the side of the outer shell 41 near the crushing box 11. The support block 7 is fixedly connected to the crushing box 11. By setting the support block 7, the conveying mechanism 4 is further supported, and the stability of the conveying mechanism 4 is increased.
[0033] Working principle: In actual use, start motor one, motor two and stirring mechanism 3, then put the straw into crushing box 11, crush the straw by crushing roller 12, and the crushed straw falls onto the inclined plate 6 of screening box 21. Then the material slides down the inclined plate 6 onto screen 22. At this time, the shaking mechanism 5 drives the screen 22 to shake, so that the qualified straw falls directly from the mesh of screen 22 into the mixing tank of stirring mechanism 3 to mix with yeast. The unqualified straw is discharged from the discharge port 23, slides down the inclined discharge plate 46 into the outer shell 41 of conveying mechanism 4, and then the conveying mechanism 4 conveys the straw upward and discharges it from the discharge plate 45, and re-enters crushing box 11 for crushing.
[0034] The principle of crushing and upward conveying: The drive of motor 1 causes the left crushing roller 12 and the corresponding gear 13 to rotate counterclockwise. Through the meshing between the two gears 13, the right crushing roller 12 rotates in the opposite direction (clockwise) at the same time. At the same time, the left crushing roller 12 is driven by the synchronous belt to make the upper shaft 42 rotate clockwise, which in turn drives the belt 43 to rotate in a cycle. Since the scraper 44 is in close contact with the inner wall of the outer shell 41, when the belt 43 rotates, the scraper 44 moves synchronously, pushing the straw at the bottom of the outer shell 41 obliquely to the top, realizing the cyclic conveying of straw that does not meet the standards.
[0035] The working principle of the shaking mechanism 5: The motor 2 drives the rotating shaft 56 and the elliptical wheel 57 to rotate. When the protruding part of the elliptical wheel 57 contacts the moving plate 54, it pushes the moving plate 54 upward, which in turn drives the guide rod 52 to slide upward in the fixed plate 53, causing the screen 22 to move upward synchronously. As the elliptical wheel 57 continues to rotate, when the non-protruding part contacts the moving plate 54, the moving plate 54 falls back under its own weight and the elastic force of the spring 55, driving the guide rod 52 and the screen 22 downward, thereby realizing the up-and-down reciprocating shaking of the screen 22. During the upward movement of the moving plate 54, the spring 55 is compressed and contracts, and the telescopic rubber sleeve 58 is compressed accordingly.
[0036] The mixing mechanism 3 uses the combination of the mixing shaft and the mixing blades to mix the straw and yeast.
[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
