Description

Technical Field

[0001] This utility model relates to the field of crop crushing technology, specifically a combined grain huller crushing component. Background Technology

[0002] A grain huller is a primary grain processing device used to remove the outer husk of grains (such as rice husks and wheat bran) and can be equipped with crushing and grading functions. It is widely used in agricultural cooperatives, grain storage enterprises, feed processing plants, and food production enterprises. Its core function is to separate the grain from the husk through mechanical action (squeezing, friction, and impact), and it can be used in conjunction with crushing equipment to process the hulled grain into pellets or powder for feed production.

[0003] A search revealed a rapid crop pulverizing device (CN217608449U), comprising a main body, a feed inlet fixedly connected to the top of the main body, a discharge outlet at the bottom of the main body, a discharge cover plate rotatably connected to the outside of the main body matching the specifications of the discharge outlet, a partition slidably connected inside the main body, a pulverizing trough inside the main body, a first motor fixedly connected to the bottom of the pulverizing trough, a pulverizing rod rotatably connected inside the pulverizing trough, a pulverizing impeller fixedly connected to the outside of the pulverizing rod, and a feeding trough inside the main body.

[0004] The technical solution has at least the following drawbacks: although it can crush grain husks, it cannot discharge them intermittently, leading to a large accumulation of husks that affects the crushing effect. Furthermore, it is inconvenient to filter and crush the husks to ensure they are fully crushed, necessitating improvement. Therefore, we propose a combined hulling machine crushing component. Utility Model Content

[0005] The purpose of this utility model is to provide a combined grain hulling and crushing component, which solves the problem mentioned in the background art that the grain hulls cannot be discharged intermittently, resulting in a large accumulation of grain hulls and thus affecting the crushing effect, and that it is inconvenient to crush and filter the grain hulls to ensure that the grain hulls can be fully crushed.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined grain huller crushing assembly, comprising a housing, a feeding funnel connected to the upper end of the housing, a ramp fixedly installed at the lower end of the inner cavity of the housing, a mesh cylinder fixedly installed at the upper end of the inner cavity of the housing, a crushing motor disposed in the lower inner cavity of the ramp, a crushing blade shaft installed at the output end of the crushing motor, a fixing rod rotatably mounted on the other side of the ramp via a bearing, a first gear fixedly installed at the lower end of the fixing rod, a second gear fixedly installed in the middle of the crushing blade shaft, a baffle fixedly installed at the upper end of the fixing rod, a plurality of square grooves opened on the surface of the baffle, a through groove opened on one side of the feeding funnel, and a plurality of rubber rods fixedly installed in the middle of the fixing rod.

[0007] By adopting the above technical solution, the fixed rod can drive the baffle to rotate. Since the small gear of the second gear drives the large gear of the first gear to rotate, the first gear will rotate once only after the second gear rotates multiple times. Therefore, the square groove on the baffle can intermittently overlap with the discharge channel of the feed funnel, thereby achieving the effect of intermittently discharging the grain husks. This avoids the situation where a large amount of grain husks accumulates and affects the crushing effect. At the same time, during the rotation of the fixed rod, the rubber rod on the fixed rod will continuously tap the screen cylinder, thereby causing the screen cylinder to vibrate. This facilitates the filtering of the crushed grain husks, leaving the grain husks that do not meet the size requirements in the screen cylinder for further crushing, thus ensuring that the grain husks are fully crushed.

[0008] Optionally, the size of the baffle is adapted to the size of the through groove, and the baffle is movably connected to the through groove.

[0009] By adopting the above technical solution and setting the through groove, the baffle can be easily rotated within the through groove.

[0010] Optionally, the square slots are configured as three, and the square slots are arranged in a ring.

[0011] By adopting the above technical solution and setting up a square trough, it is convenient to discharge the grain husks into the mesh cylinder for crushing.

[0012] Optionally, the shredder shaft is located in the middle of the inner cavity of the mesh cylinder, and the shredder blades on the shredder shaft are arranged in a ring.

[0013] By adopting the above technical solution, the crushing blade shaft is configured to crush the grain husks inside the mesh cylinder.

[0014] Optionally, the size of the mesh cylinder is larger than the size of the lower opening of the feed funnel.

[0015] By adopting the above technical solution, it is convenient to receive and crush the grain husks falling from the feed hopper.

[0016] Optionally, the first gear meshes with the second gear, and a protective shell is provided on the outer side of the first gear and the second gear.

[0017] By adopting the above technical solution, the meshing point of the first gear and the second gear can be protected by the protective shell on the outside of the first gear and the second gear.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] The technical solution of this application, through the design of a housing, feeding hopper, screen cylinder, crushing motor, crushing blade shaft, second gear, baffle, and through groove, allows the fixed rod to drive the baffle to rotate. Since the small gear of the second gear drives the large gear of the first gear, the second gear rotates multiple times before the first gear rotates once. This allows the square groove on the baffle to intermittently overlap with the discharge channel of the feeding hopper, thus achieving the effect of intermittently discharging the grain husks and avoiding the accumulation of a large amount of grain husks that affects the crushing effect. At the same time, during the rotation of the fixed rod, the rubber rod on the fixed rod continuously taps the screen cylinder, causing the screen cylinder to vibrate. This facilitates the filtering of the crushed grain husks, leaving the grain husks that do not meet the size requirements inside the screen cylinder for further crushing, thereby ensuring that the grain husks are fully crushed.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a combined grain huller crushing component, including a housing 1, with a feeding funnel 11 connected to the upper end of the housing 1, a ramp 12 fixedly installed at the lower end of the inner cavity of the housing 1, a mesh cylinder 13 fixedly installed at the upper end of the inner cavity of the housing 1, a crushing motor 14 disposed in the lower inner cavity of the ramp 12, a crushing blade shaft 15 installed at the output end of the crushing motor 14, a fixing rod 2 rotatably mounted on the other side of the ramp 12 via a bearing, a first gear 21 fixedly installed at the lower end of the fixing rod 2, a second gear 22 fixedly installed in the middle of the crushing blade shaft 15, a baffle 24 fixedly installed at the upper end of the fixing rod 2, a plurality of square grooves 25 opened on the surface of the baffle 24, and a passage opening on one side of the feeding funnel 11. Multiple rubber rods 3 are fixedly installed in the middle of the groove 4 and the fixing rod 2. The crushing blade shaft 15 is set in the middle of the inner cavity of the mesh cylinder 13, and the crushing blades on the crushing blade shaft 15 are distributed in a ring. Through the setting of the crushing blade shaft 15, the crushing blade shaft 15 can crush the grain husks in the mesh cylinder 13. The size of the mesh cylinder 13 is larger than the lower opening size of the feed funnel 11, which facilitates the collection and crushing of the grain husks falling from the feed funnel 11. The first gear 21 and the second gear 22 mesh, and the outer sides of the first gear 21 and the second gear 22 are provided with protective shells. Through the protective shells on the outer sides of the first gear 21 and the second gear 22, the meshing part of the first gear 21 and the second gear 22 can be protected.

[0026] The size of the baffle 24 is adapted to the size of the through groove 4, and the baffle 24 is movably connected to the through groove 4. The through groove 4 facilitates the rotation of the baffle 24 within the through groove 4.

[0027] Three square troughs 25 are provided, and the square troughs 25 are arranged in a ring. The square troughs 25 facilitate the discharge of grain husks into the mesh cylinder 13 for crushing.

[0028] During crushing, firstly, connect the feed funnel 11 to the grain husk discharge pipe of the huller so that the grain husks discharged from the huller can be discharged into the feed funnel 11. Then, turn on the crushing motor 14, which drives the crushing blade shaft 15 to rotate. The crushing blade shaft 15 crushes the grain husks that fall into the mesh cylinder 13. At the same time, during the rotation of the crushing blade shaft 15, the second gear 22 on the crushing blade shaft 15 drives the first gear 21 to rotate. The first gear 21 drives the fixed rod 2 to rotate, which in turn causes the fixed rod 2 to drive the baffle 24 to rotate as well. Since the small gear of the second gear 22 drives the large gear of the first gear 21 to rotate, therefore... The second gear 22 rotates multiple times before driving the first gear 21 to rotate once. Therefore, the square groove 25 on the baffle 24 can intermittently overlap with the discharge channel of the feed funnel 11, thereby achieving the effect of intermittently discharging the grain husks. This avoids the situation where a large amount of grain husks accumulates and affects the crushing effect. At the same time, during the rotation of the fixed rod 2, the rubber rod 3 on the fixed rod 2 will continuously knock on the screen cylinder 13, thereby causing the screen cylinder 13 to vibrate. This facilitates the filtering of the crushed grain husks, leaving the grain husks that do not meet the size requirements in the screen cylinder 13 for further crushing, thus ensuring that the grain husks can be fully crushed.
