Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, specifically to a grain gravity destoner. Background Technology

[0002] Gravity destoners are grain or granular material processing equipment that utilizes the difference in specific gravity between materials and impurities such as stones, combined with airflow and vibration, to achieve grading and impurity removal. They are an indispensable component in grain processing. Currently, when grain destoners process grains, they are equipped with internal screen plates to effectively separate grains and impurities. For example, patent document CN218190922U discloses a suction-type gravity destoner for grain with an adjustable screen plate angle. This gravity destoner uses a first motor to rotate an eccentric wheel, which in turn causes a connecting rod to drive the screen plate to swing up and down. When the screen plate contacts the limiting plate, it will collide with the limiting plate, causing the screen plate to vibrate. This allows for the rapid screening of stones and impurities on the screen plate.

[0003] In order to avoid clogging, the screen plate inside the gravity destoner is scraped with a brush to remove impurities from the surface of the screen plate. However, when the brush comes into contact with the screen plate, there is both sliding friction and squeezing friction, which makes it easy for impurities to be squeezed and continuously penetrate into the screen plate, seriously affecting the separation effect of the screen plate.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model discloses a grain gravity destoner.

[0019] This utility model provides, for example Figure 1-4 The grain destoner shown includes a destoner housing 1 and a material pipe 2 connected to the top of the destoner housing 1. The outer wall of the destoner housing 1 is screwed with a door 18, and the top of the material pipe 2 is connected to a hopper 3. A screen plate 4 is fixedly provided on the upper end of the inner wall of the gravity destoner housing 1, and a discharge hole 5 is provided on the upper end of the outer wall of the gravity destoner housing 1. The discharge hole 5 is matched with the bottom of the screen plate 4. The upper part of the internal structure of the gravity destoner housing 1 is provided with a transmission assembly, and multiple spaced elastic support assemblies are provided through the transmission assembly. The upper end of the elastic support assembly is provided with a top block 6. The elastic support assembly includes a sleeve 9 and a sleeve rod 10. The sleeve rod 10 is slidably disposed in the sleeve 9. The sleeve 9 is fixedly connected to the transmission assembly. The sleeve rod 10 is fixedly connected to the top block 6. A spring 11 is sleeved on the rod wall of the sleeve rod 10. The two ends of the spring 11 are fixedly connected to the top block 6 and the sleeve 9 respectively. A guide rod 7 is fixedly inserted inside the top block 6. Multiple spaced guide plates 8 are fixedly provided on the upper part of the inner wall of the gravity destoner housing 1. The guide rod 7 and the guide plate 8 are configured to cooperate. The upper ends of the multiple guide plates 8 are all bent. The top block 6 and the bottom of the screen plate 4 are impacted and cooperated. The transmission assembly includes two transmission rollers 12, both of which are rotatably mounted on the back side of the gravity destoner housing 1. The roller walls of the transmission rollers 12 are equipped with transmission belts 13, which are fixedly connected to the sleeves 9. A motor 14 is fixedly mounted on the back side of the gravity destoner housing 1, and the output shaft of the motor 14 is fixedly connected to the transmission rollers 12.

[0020] In order to effectively remove and collect impurities when separating impurities and grains using a sieve plate, such as... Figure 1As shown, two symmetrically arranged hooks 15 are fixedly provided on the outer wall of the gravity destoner housing 1 and at the lower end of the discharge hole 5. A receiving box 16 is provided at the lower end of the outer wall of the gravity destoner housing 1, and a hanging hole 17 for attaching to the hooks 15 is provided on the upper side of the receiving box 16.

[0021] Working principle: When in use, first hang and fix the receiving box 16 to the hook 15 on the outer wall of the gravity destoner box 1 through the hanging hole 17 to ensure that the impurity collection device is installed in place. Then open the box door 18 to check whether the screen plate 4 is flat and whether the elastic support component is intact. After confirming that there is no abnormality in the equipment, close the box door 18 and slowly feed the grain to be destoned (such as wheat, rice, etc.) into the hopper 3. Under the action of gravity, the grain enters the interior of the gravity destoner box 1 evenly through the feed pipe 2 and finally spreads evenly on the surface of the screen plate 4 to start the gravity separation operation. When the motor 14 is started, the output shaft of the motor 14 drives the transmission roller 12 fixed thereto to rotate. Since the two transmission rollers 12 are connected by a transmission belt 13, the actively rotating transmission roller 12 will drive the transmission belt 13 to run smoothly along the track formed by the two transmission rollers 12. Multiple elastic support components (composed of sleeve 9, sleeve rod 10 and spring 11) fixedly connected to the transmission belt 13 move synchronously with the transmission belt 13. When the elastic support components move to the vicinity of the guide plate 8 on the inner wall of the gravity destoner housing 1, the guide rod 7 fixedly inserted inside the top block 6 will first contact the bent end of the guide plate 8. As the transmission belt 13 continues to drive the elastic support assembly to move, the guide rod 7 gradually slides downward along the bending surface of the guide plate 8. During this process, the guide rod 7 generates a downward thrust on the top block 6, pushing the top block 6 to move away from the screen plate 4. At the same time, the top block 6 drives the sleeve rod 10 to slide downward along the inner wall of the sleeve 9. The spring 11 sleeved on the wall of the sleeve rod 10 is compressed by the top block 6 and the sleeve 9 and contracts to store energy. When the guide rod 7 completely separates from the guide plate 8, the guide rod 7 loses its supporting force. At this time, the contracted spring 11 quickly releases its stored energy, generating an upward elastic force to push the top block 6 to quickly reset. The upper end face of the top block 6 violently impacts the bottom of the screen plate 4. As multiple elastic support components move continuously in a cycle with the transmission belt 13, each top block 6 periodically cooperates with the guide plate 8 and drives the top block 6 to strike the screen plate 4. Multiple top blocks 6 form a continuous and uniform knocking vibration on the bottom of the screen plate 4. This vibration can shake out the impurities stuck in the holes of the screen plate 4, and prevent the screen plate 4 from being blocked and affecting the separation effect. While the top block 6 continuously strikes the screen plate 4, the grains on the screen plate 4 are separated due to differences in specific gravity. The pure grains with lower density move along the surface of the screen plate 4 towards the discharge hole 5 under the support and slight vibration of the screen plate 4, and are finally discharged from the equipment through the discharge hole 5 to enter the subsequent processing stage. The impurities such as stones and mud with higher density are difficult to move with the grains and are easily peeled off by the vibration of the screen plate 4. They will fall off the surface of the screen plate 4 and fall into the receiving box 16 below for collection. When the impurities in the receiving box 16 accumulate to a certain amount, the receiving box 16 can be removed to empty the impurities. The box door 18 should be opened regularly to check the wear of the screen plate 4, the transmission belt 13 and the elastic support components. Damaged parts should be replaced in time to ensure the long-term stable operation of the equipment.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
