Description

TECHNICAL FIELD

[0001] The utility model relates to feed production technical field, and the specific field is a feed processing with iron removal device. BACKGROUND

[0002] In feed processing, raw materials are widely sourced, including grains (such as corn, wheat), legumes (such as soybeans), meal (such as soybean meal, rapeseed meal), minerals (such as dicalcium phosphate), vitamin premix and other ingredients. These raw materials are easily mixed with various iron impurities during planting, harvesting, transportation and storage. For example, grains may be mixed with iron filings dropped by farm tools during harvesting; mineral raw materials may be mixed with small iron blocks dropped by ore mining equipment during mining and transportation, and iron impurities mixed in feed may enter the pulverizer, and under the action of high-speed rotating blades, iron filings may cause the blades to wear out, shortening the service life of the blades. In the mixer, iron impurities may collide with the stirring paddle, damaging the surface coating of the stirring paddle and affecting its stirring performance.

[0003] In the iron removal equipment for feed processing, permanent magnets are commonly used components. Permanent magnets can generate a magnetic field, and when feed raw materials pass through the magnetic field area, iron impurities will be magnetized. According to the principle that magnetic substances repel each other and attract each other, iron impurities will be attracted by permanent magnets.

[0004] The existing iron removal device can only attract iron impurities close to its surface when facing large quantities of feed, and thick feed wrapped with iron cannot be attracted. UTILITY MODEL CONTENTS

[0005] The utility model discloses in order to solve the technical problem that the existing technology's iron removal device can only attract the iron impurity close to its surface when facing large quantities of feed, and thick feed wrapped with iron cannot be attracted, and further provides an iron removal device for feed processing.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: an iron removal device for feed processing, comprising: a sieve plate, the sieve plate is inclined from front to back, the left and right side walls of the sieve plate are connected with slide rods, the slide rods are slidingly connected in the rack, a high-frequency reciprocating cylinder is connected between the rack and the side wall of the sieve plate, a magnetic plate slot is formed in the bottom wall of the sieve plate, a magnetic plate is arranged in the magnetic plate slot, the magnetic plate has magnetism, the magnetic plate is connected with a rotating shaft, the rotating shaft is rotatably connected in the sieve plate, the rotating shaft is connected with a locking adjustment mechanism, the locking adjustment mechanism can make the upper and lower surfaces of the magnetic plate and the sieve plate bottom plate coincide by adjusting the rotating angle of the rotating shaft, a scrap removal mechanism is in contact with the outer wall of the sieve plate bottom plate, and the scrap removal mechanism can scrape off the iron filings on the lower surface of the magnetic plate.

[0007] Preferably, the locking adjustment mechanism includes gears, one end of each rotating shaft is connected to a gear, all gears are meshed with a rack with a gap, the rack is connected to the telescopic end of the adjusting cylinder, and the fixed end of the adjusting cylinder is connected to the frame.

[0008] Preferably, the bottom wall of the sieve plate is provided with a lifting slide groove, which is parallel to the magnetic plate groove. A baffle is slidably connected in the lifting slide groove. When the upper end of the baffle is flush with the upper surface of the sieve plate, the lower end of the baffle contacts the base circle of the cam. The cam is connected to the camshaft, which is rotatably connected in the bracket. The bracket is connected to the lower surface of the sieve plate, and one end of the camshaft is connected to a gear.

[0009] Preferably, the scraping mechanism includes rollers, the roller shaft ends are rotatably connected to the frame and connected to the power source, the two rollers are connected by a scraping belt, a scraping plate is connected to the scraping belt, and the scraping plate is in contact with the lower surface of the screen plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] Driven by a high-frequency reciprocating cylinder, the screen plate moves back and forth, causing the feed to be spread into a thin layer on the upper surface of the screen plate and roll down along the inclined surface of the screen plate. The iron in the thin feed is attracted by the magnetic plate, which solves the technical problem in the existing technology that the thicker feed carries iron and cannot be attracted. After one side of the magnetic plate is full, the magnetic plate is controlled to rotate to the other side to continue attracting. The iron filings on the lower surface of the magnetic plate are scraped off by the scraping mechanism, cleaning the iron filings on the lower surface of the magnetic plate. This cycle is repeated to achieve cleaning of the magnetic plate surface and collection of iron filings.

[0012] When the rack and pinion drives the magnetic plate to flip through the gears, it also drives the cam to rotate. The cam drives the baffle to rise and block the feed from continuing to be fed. After the magnetic plate flips, the baffle is completely lowered and screening continues. In this way, there is no need to stop feeding when the magnetic plate flips, making the production more continuous and automatic. Attached Figure Description

[0018] 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.

[0019] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to the connection method that allows movement through connecting parts such as hinges, pins, and short shafts.

[0020] The present invention will now be described in detail with reference to the accompanying drawings. Example

[0021] The following is in conjunction with the appendix Figures 1-4 This embodiment describes an iron removal device for feed processing, comprising: a sieve plate 1, which is inclined from front to back; sliding rods 2 connected to the left and right side walls of the sieve plate 1, which are slidably connected to a frame 3; a high-frequency reciprocating cylinder 4 connected between the frame 3 and the side walls of the sieve plate 1; a magnetic plate groove 5 opened on the bottom wall of the sieve plate 1, and a magnetic plate 6 disposed in the magnetic plate groove 5; the magnetic plate 6 is magnetic; the magnetic plate 6 is connected to a rotating shaft 7, which is rotatably connected to the sieve plate 1; the rotating shaft 7 is connected to a locking adjustment mechanism 8, which can adjust the rotation angle of the rotating shaft 7 to make the upper and lower surfaces of the magnetic plate 6 coincide with the bottom plate of the sieve plate 1; and a scraping mechanism 9 in contact with the outer wall of the bottom plate of the sieve plate 1, which can scrape off iron filings from the lower surface of the magnetic plate 6.

[0022] During use, the sieve plate 1 moves back and forth under the drive of the high-frequency reciprocating cylinder 4, causing the feed to be spread into a thin layer on the upper surface of the sieve plate 1 and roll down along the inclined surface of the sieve plate 1. The iron in the thin feed is adsorbed by the magnetic plate 6, which solves the technical problem in the prior art that the thicker feed carries iron and cannot be adsorbed. After one side of the magnetic plate 6 is full, the feeding stops. The locking adjustment mechanism 8 drives all the rotating shafts 7 to rotate 180° synchronously. The rotating shafts 7 drive the magnetic plate 6 to rotate 180° so that the magnetic plate 6 flips over and overlaps with the upper and lower sides of the bottom plate of the sieve plate 1. The clean side of the magnetic plate 6 flips to the upper part to continue adsorption. The iron filings on the lower surface of the magnetic plate 6 are scraped off by the scraping mechanism 9 to clean the iron filings on the lower surface of the magnetic plate 6. This cycle is repeated to achieve cleaning of the magnetic plate surface and collection of iron filings.

[0023] The locking adjustment mechanism 8 includes gears 81. One end of each rotating shaft 7 is connected to gear 81. All gears 81 are meshed with rack 82 with a gap. Rack 82 is connected to the telescopic end of adjusting cylinder 83. The fixed end of adjusting cylinder 83 is connected to frame 3.

[0024] When all rotating shafts 7 need to rotate 180° synchronously, the control adjustment cylinder 83 retracts to a specified length. The extension and retraction end of the adjustment cylinder 83 drives the rack 82 to move, and the rack 82 drives all gears 81 to rotate 180° synchronously. The gears 81 drive the rotating shafts 7 to rotate, thus completing the adjustment. Since there is a gap between the gears 81 and the rack 82, the gears 81 and the rack 82 will not wear when the screen plate 1 reciprocates.

[0025] The bottom wall of the sieve plate 1 is provided with a lifting slide groove 10, which is parallel to the magnetic plate groove 5. A baffle 11 is slidably connected in the lifting slide groove 10. When the upper end of the baffle 11 is flush with the upper surface of the sieve plate 1, the lower end of the baffle 11 is in contact with the base circle of the cam 12. The cam 12 is connected to the camshaft 13, which is rotatably connected in the bracket 14. The bracket 14 is connected to the lower surface of the sieve plate 1, and one end of the camshaft 13 is connected to the gear 81.

[0026] When the rack 82 drives the magnetic plate 6 to flip through the gear 81, it also drives the camshaft 13 to rotate through the gear 81. The camshaft 13 drives the cam 12 to rotate. The cam 12 drives the baffle 11 to rise in the lifting chute 10 to block the feed from continuing to be fed. After the magnetic plate 6 flips, the baffle 11 is completely lowered and screening continues. In this way, the feed does not need to be stopped when 11 flips, making the production more continuous and automatic.

[0027] The scraping mechanism 9 includes a roller 91, the shaft end of which is rotatably connected to the frame 3 and connected to the power source. Two rollers 91 are connected by a scraping belt 92, and a scraping plate 93 is connected to the scraping belt 92. The scraping plate 93 is in contact with the lower surface of the screen plate 1.

[0028] The power is transmitted through the roller 91 to drive the scraper belt 92 to rotate. The scraper belt 92 drives the scraper plate 93 to scrape off the iron filings on the lower surface of the magnetic plate 6 and discharge them through the scraper belt 92. When the magnetic plate 6 is flipped, the scraper plate 93 is controlled to be located below the scraper belt 92 so as not to interfere with the magnetic plate 6.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.
