Abstract
Description
Technical Field
[0001] This utility model belongs to the field of feed processing technology, and in particular relates to a multi-chamber feed grinder. Background Technology
[0002] Feed is a crucial element of modernization and scientific management in animal husbandry. Compound feed can be customized to the different growth stages of animals (such as pigs, poultry, and ruminants), supplementing essential minerals and vitamins and avoiding nutritional imbalances common in traditional feeding methods. Feed grinders significantly increase the surface area of feed by reducing particle size, allowing digestive enzymes in animals to more fully contact the nutrients in the feed, thereby improving the digestibility of nutrients such as protein and starch. However, traditional feed grinders still have the following problems in their current use:
[0003] 1. Traditional feed grinders are usually one-piece structures. In the long-term feed grinding work, some components will inevitably wear out. Due to the one-piece structure, it is not easy to replace or repair the problematic components, which leads to a decrease in the working efficiency of the feed grinder and may also result in poor feed quality, affecting the digestion of animals.
[0004] 2. Traditional feed grinders cannot screen the ground feed, resulting in feed of varying sizes, which significantly affects the digestive system, nutrient absorption, feed intake, and feed utilization of poultry.
[0005] 3. Traditional feed grinders typically feed feed directly into the inlet, making it impossible to screen the feed. If the feed contains small stones, it will severely damage the grinder's blades, thus affecting the grinding effect and increasing maintenance costs.
[0006] To address these issues, we provide a multi-chamber feed grinder. Utility Model Content
[0007] The purpose of this utility model is to provide a multi-chamber feed grinder, which solves the problems of existing multi-chamber feed grinders being unable to maintain individual components, unable to screen the ground feed, and unable to remove stones from the added feed by setting up a grinding chamber, a screening component, and an air classifier.
[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0009] This utility model is a multi-chamber feed grinder, including a base, a grinding box, a screening component and an air classifier; the grinding box and a fixed platform are fixedly connected side by side on the upper end of the base, and a connecting piece is provided on the side of the grinding box away from the fixed platform;
[0010] The base provides a supporting structure for the entire feed grinder, enabling the feed grinding operation to proceed normally and stably;
[0011] The upper end of the crushing box is provided with a feed inlet, and an air classifier is provided at the top of the feed inlet. A screening component is movably connected through the inside of the crushing box. Two baffles that are symmetrically distributed and inclined towards the upper end of the screen are fixedly connected to the inner wall of the crushing box below the feed inlet. A rotating shaft is rotatably connected inside the crushing box. A rotating cylinder is fixedly connected to the circumference of the rotating shaft. Crushing blades that are arranged in a ring array are fixedly connected to the circumference of the rotating cylinder. Crushing teeth are provided on the lower inclined surface of the baffles near the crushing blades.
[0012] The air separator can be removed from the top of the crushing box. When crushing feed, the feed first passes through the air separator to remove foreign objects such as stones. Then, it enters the crushing box through the feed inlet. During the crushing process, the rotating shaft drives the rotating drum and the crushing blades around the drum to rotate together. The crushing blades drive the feed to move inside the crusher. When it moves to the lower inclined surface of the baffle, because the distance between the crushing teeth and the crushing blades is very close, large particles of feed will be crushed into small particles as they pass through.
[0013] The screening assembly includes a screen, end cap one, and end cap two. End cap one and end cap two are located at both ends of the screen and are respectively inserted and fixed to the screen. The screen is located on the outer periphery of the crushing blades. The end of end cap one away from the screen is attached to the inner wall of the crushing box near end cap one. The end of end cap two near the screen is attached to the inner wall of the crushing box near end cap two. The end of end cap two near the screen and the inner wall of the crushing box near end cap two are on the same vertical plane.
[0014] End cap one and end cap two provide support for the screen, allowing the screen to perform normal screening inside the crusher. At the same time, because the screen is located on the outside of the crushing blades and end cap one and end cap two are fitted to the inner wall of the crushing chamber, the crushed feed particles can only pass through the crushing chamber and enter the next process if they pass through the screening component. The feed that cannot pass through the screening component remains inside the crusher and continues to be crushed with the movement of the crushing blades until it passes through the screening component.
[0015] Furthermore, four external support bones are fixedly connected between end cap one and end cap two, and the external support bones are located outside the screen. Four internal support bones are also fixedly connected between end cap one and end cap two, and the internal support bones are located inside the screen. Two support rods are also fixedly connected between end cap one and end cap two, and the support rods are located at the upper end of the screen. The top end of the support rod is attached to the bottom end of the baffle. Two symmetrically distributed handles are fixedly connected to the outer side of the end face of end cap two away from the screen. A through groove matching the size of end cap two is opened in the connector. The end of end cap two near the screen extends into the through groove of the connector. The end of end cap two away from the screen and the end of connector away from the crushing box are fixed by bolts and nuts.
[0016] The inner and outer skeleton supports and the support rods strengthen the support of the screen provided by end cap one and end cap two, so that the screen will not deform during the crushing process and can perform the screening work normally. At the same time, the screw-on fixing method of end cap two and the connecting parts ensures that the entire screening assembly will not move at will during the crushing process. When the screening assembly is damaged, simply remove the bolts and pull the handle to pull the screening assembly out of the crushing box for repair.
[0017] Because the through groove inside the connector matches the size of the end cap, and the top of the support rod fits the bottom of the baffle, the feed can only move out of the crushing box by passing through the screen holes during the crushing process.
[0018] Furthermore, a crossbar is provided inside the crushing box at the bottom of the screening component, and the upper end of the crossbar is in contact with the lowest point of the screening component; the crossbar provides support for the screening component, so that the screening component can screen the feed normally and stably during the crushing operation.
[0019] Furthermore, a discharge port is provided at the lower end of the crushing box, and the discharge port extends through the base; the small feed particles screened by the screen move towards the discharge port under the action of gravity, and then enter the next process through the gap between the feed port and the base.
[0020] Furthermore, a motor is fixedly connected to the upper end of the fixed platform, and the end of the rotating shaft near the motor extends through the crushing box and is connected to the output end of the motor for transmission. Bearings are fixedly connected to both ends of the crushing box, and the rotating shaft is rotatably connected to the bearings.
[0021] The fixed platform provides support for the motor. With the bearing and the fixed platform working together to fix it, when the motor is started, the output end of the motor can drive the rotating shaft to rotate, thereby performing the feed crushing work.
[0022] Furthermore, the air separator has a second feed inlet at its upper end, and two inclined plates, one and two, are provided at the upper end of the air separator. The bottom of the first inclined plate points towards the lower middle part of the second inclined plate. An inclined plate, the third inclined plate, is also provided inside the air separator. The bottom of the second inclined plate points towards the lower middle part of the third inclined plate. Two air inlets are provided through the air separator at a position lower than the bottom of the third inclined plate on the inner wall of the side of the air separator closest to the third inclined plate. The bottom of the air separator is fixedly connected to a first slope and a second slope. The tops of the first and second slopes overlap and are lower than the air inlets. The bottom of the air separator at the lower end of the first slope has a second discharge outlet, and the bottom of the air separator at the lower end of the second slope has a third stone outlet.
[0023] The stone outlet is connected to a debris collection device, and the air inlet is connected to a blower. When performing air separation, the blower is started first, and the air blown by the blower is blown into the air separator through the air inlet. Then, the feed to be separated is added. The feed added from the feed inlet 2 either moves directly along the inclined plate 2 to the inclined plate 3, or it moves first from the inclined plate 1 to the inclined plate 2, and then to the inclined plate 3. When it reaches the bottom of the inclined plate 3, due to the wind force, the lighter feed will move with the wind to the inclined slope 1, and finally move along the inclined slope 1 to the discharge outlet 2, and enter the crushing box through the discharge outlet 2 and the feed inlet 1. The heavier stones move to the inclined slope 2, move along the inclined slope 2 to the stone outlet, and enter the debris collection device through the stone outlet.
[0024] Furthermore, the air separator also includes an air damper assembly, which includes two rotating rods, with one end of the rotating rod away from the motor passing through and extending out of the air separator. A baffle plate is fixedly connected to the periphery of the rotating rod, and a belt is driven to the periphery of the two rotating rods extending out of the air separator.
[0025] Rotating one of the levers causes the other lever to rotate as well, and the wind deflector fixed around the lever's center axis also rotates. Since the two deflectors are at the same height as the two air inlets, the air entering from the air inlets will be blocked by the deflectors. Adjusting the position of the deflectors can control the wind force.
[0026] Furthermore, an arc-shaped damper adjustment groove is provided on the side of the air separator away from the motor. An adjustment handle is fixedly connected to the outer side of the rotating rod located above, away from the air separator. The end of the adjustment handle away from the rotating rod is movably inserted into the damper adjustment groove.
[0027] Rotating the adjustment handle will cause the rotating rod and baffle to rotate. The adjustment handle makes it easier to adjust the wind force, while the damper adjustment slot ensures that the adjustment handle can only move along a specific trajectory, making it convenient to rotate the adjustment handle.
[0028] This utility model has the following beneficial effects:
[0029] This invention solves the problem of traditional feed grinders failing to operate as a whole due to a problem with a single module by setting up a grinding box, a screening component, and an air classifier. The feed first passes through the air classifier to remove stones before entering the grinding box for grinding. The fully ground feed then passes through the screen and moves out of the grinding box from the discharge port to the next process. The grinding box is fixed to the end cap of the screening component by connecting parts. The air classifier is detachable. When the grinding box, screening component, or air classifier malfunctions, the faulty component is disassembled and a spare component is installed, allowing the feed grinding to resume. The disassembled component is then repaired and maintained, thereby improving maintenance efficiency and saving maintenance costs.
[0030] This invention solves the problem of uneven feed particle size after crushing by setting up a screening component. Only when the feed particles reach a certain size can they pass through the screen holes and enter the next processing step through the discharge port of the crushing box under the action of gravity. Feed particles that cannot pass through the screen remain inside the crushing box and continue to be crushed by the crushing blades and crushing teeth until they pass through the screen holes, thus achieving the purpose of screening the crushed feed particles, improving feed utilization and saving costs.
[0031] This invention solves the problem of removing stones from added feed by incorporating an air separator. Feed is added through inlet two. Due to the light weight of feed and the heavy weight of stones, the feed enters the crushing chamber through outlet two under the combined action of inclined plates one, two, three, slope one, slope two, and the air inlet, while the stones move out of the air separator through the stone outlet. This achieves the purpose of removing stones mixed in with the feed, preventing damage to the crushing blades, and reducing maintenance costs.
[0032] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0045] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1
[0046] Please see Figure 1-5This utility model is a multi-chamber feed grinder, including a base 1, a grinding box 2, a screening component 3 and an air classifier 4; the grinding box 2 and a fixed platform 101 are fixedly connected side by side at the upper end of the base 1, and a connecting piece 206 is provided on the side of the grinding box 2 away from the fixed platform 101.
[0047] The base 1 provides a supporting structure for the entire feed grinder, enabling the feed grinding operation to proceed normally and stably;
[0048] The upper end of the crushing box 2 is provided with a feed inlet 201. The top of the feed inlet 201 is fixedly connected to an air classifier 4. The crushing box 2 is movably connected to a screening component 3. The inner wall of the crushing box 2 at the lower end of the feed inlet 201 is fixedly connected to two baffles 202 that are symmetrically distributed and inclined towards the upper end of the screen 301. The crushing box 2 is rotatably connected to a rotating shaft 203. A rotating cylinder 204 is fixedly connected to the circumference of the rotating shaft 203. Crushing blades 2041 arranged in a ring array are fixedly connected to the circumference of the rotating cylinder 204. Crushing teeth 2021 are provided on the lower inclined surface of the baffles 202 near the crushing blades 2041.
[0049] The air separator 4 is detachable. The feed first passes through the air separator 4 to remove foreign objects such as stones mixed in. Then, it enters the crushing box 2 through the feed inlet 201. During the crushing operation, the rotating shaft 203 rotates, driving the rotating drum 204 and the crushing blades 2041 around the rotating drum 204 to rotate together. The crushing blades 2041 drive the feed to move inside the crusher. When it moves to the lower inclined surface of the baffle 202, because the distance between the crushing teeth 2021 and the crushing blades 2041 is very close, large feed particles will be crushed into small feed particles when they pass through. When the crushed feed particles reach a certain size, they can pass through the screening component 3 and then through the crushing box 2 to enter the next process. The feed that cannot pass through the screening component 3 remains inside the crusher and continues to be crushed with the movement of the crushing blades 2041 until it passes through the screening component 3 and the crushing box 2 to enter the next process.
[0050] Among them, such as Figure 1-5 As shown, the screening assembly 3 includes a screen 301, an end cap 302, and an end cap 303. Two symmetrically distributed handles 306 are fixedly connected to the outer surface of the end cap 303 away from the screen 301. A through groove matching the size of the end cap 303 is opened in the connector 206. The end of the end cap 303 near the screen 301 extends into the through groove of the connector 206, and the end of the end cap 303 away from the screen 301 is fixed to the end of the connector 206 away from the crushing box 2 by bolts and nuts.
[0051] The screw-on fixing method of end cap 303 and connector 206 ensures that the entire screening assembly 3 will not move arbitrarily during the crushing process. When the screening assembly 3 is damaged, simply remove the bolts and pull the handle 306 to pull the screening assembly 3 out of the crushing box 2 for repair. Since the through groove in connector 206 matches the size of end cap 303, and the top of support rod 307 fits the bottom of baffle 202, the feed can only move out of the crushing box 2 through the screen holes of screen 301 during the crushing process.
[0052] Among them, such as Figure 1-5 As shown, the lower end of the crushing box 2 is provided with a discharge port 208, and the discharge port 208 passes through the base 1; the small particles of feed screened by the screen 301 move towards the discharge port 208 under the action of gravity, and then enter the next process through the gap between the discharge port 208 and the base 1.
[0053] Among them, such as Figure 1-2 As shown, a motor 102 is fixedly connected to the upper end of the fixed platform 101. The end of the rotating shaft 203 near the motor 102 extends through the crushing box 2 and is connected to the output end of the motor 102. Bearings 207 are fixedly connected to both ends of the crushing box 2, and the rotating shaft 203 is rotatably connected to the bearings 207.
[0054] The fixed platform 101 provides support for the motor 102. With the joint fixation of the bearing 207 and the fixed platform 101, when the motor 102 is started, the output end of the motor 102 can drive the rotating shaft 203 to rotate, thereby performing feed crushing work. At the same time, the bearing 207 protects the rotating shaft 203, so that the rotating shaft 203 is not exposed.
[0055] The working principle of this embodiment is as follows: Under the action of gravity, the feed screened by the air classifier 4 enters the crushing box 2 through the feed inlet. The motor 102 is started, and the output end of the motor 102 drives the rotating shaft 203 to rotate. The rotating drum 204 and the crushing blades 2041 also rotate. The crushing blades 2041 drive the feed to move inside the crusher. When it moves to the lower inclined surface of the baffle 202, because the distance between the crushing teeth 2021 and the crushing blades 2041 is very close, large particles of feed will be crushed into small particles when they pass through. When the crushed feed particles reach a certain size, they can pass through the screening component 3 and then through the crushing box 2 to enter the next process. The feed that cannot pass through the screening component 3 remains inside the crusher and continues to move with the crushing blades. The feed is pulverized by the 2041 motion until it passes through the screening component 3 and the pulverizing box 2 to enter the next process. When the screening component 3 is damaged, simply remove the bolt that is screwed through the connector 206 and the end cover 203, pull the handle 306 to pull the screening component 3 out of the pulverizing box 2, insert the spare screening component 3, and disassemble and screw the end cover 203 and the connector 206 to continue the feed pulverization work. Finally, repair the damaged screening component 3. When the air separator 4 is damaged, simply remove the air separator 4, connect the spare air separator 4, continue the feed pulverization work, and then repair the damaged air separator 4. This saves time and improves maintenance efficiency and the efficiency of feed pulverization. Specific Implementation Example 2
[0056] Please see Figure 3-6 Based on the first specific embodiment, end cap 302 and end cap 303 are located at both ends of screen 301 and are respectively inserted and fixed to screen 301. Screen 301 is located on the outer side of the crushing blade 2041. The end of end cap 302 away from screen 301 is attached to the inner wall of crushing box 2 near end cap 302. The end of end cap 303 near screen 301 is attached to the inner wall of crushing box 2 near end cap 303.
[0057] End cap 302 and end cap 303 provide support for screen 301, allowing screen 301 to perform normal screening inside the crusher. At the same time, since screen 301 is located outside the crushing blade 2041 and end cap 302 and end cap 303 are fitted to the inner wall of crushing box 2, the feed will only move inside the screening component 3 with the crushing blade 2041 during the crushing process. Only when the crushed feed particles reach a certain size can they pass through the screening component 3 and then through the crushing box 2 to enter the next process. Feed that cannot pass through the screening component 3 remains inside the crusher and continues to be crushed with the movement of the crushing blade 2041 until it passes through the screening component 3 and the crushing box 2 to enter the next process.
[0058] Among them, such as Figure 3-6As shown, four external bone supports 304 are fixedly connected between end cap 1 302 and end cap 2 303, and the external bone supports 304 are located outside the screen 301. Four internal bone supports 305 are also fixedly connected between end cap 1 302 and end cap 2 303, and the internal bone supports 305 are located inside the screen 301. Two support rods 307 are also fixedly connected between end cap 1 302 and end cap 2 303, and the support rods 307 are located at the upper end of the screen 301. The top end of the support rods 307 is attached to the bottom end of the baffle 202.
[0059] The inner bone support 305, outer bone support 304 and support rod 307 strengthen the support of end cap 1 302 and end cap 2 303 for screen 301, so that screen 301 will not deform during crushing and can perform screening normally. At the same time, the setting of support rod 307 to fit the baffle 202 prevents feed from flying out from the top of screening component 3.
[0060] Among them, such as Figure 3-5 As shown, a crossbar 205 is installed inside the crushing box 2 at the bottom of the screening component 3. The upper end of the crossbar 205 is in contact with the lowest point of the screening component 3. The crossbar 205 provides support for the screening component 3. During the crushing operation, the screening component 3 can screen the feed normally and stably.
[0061] The working principle of this embodiment is as follows: Since the screen 301 is located outside the periphery of the crushing blade 2041 and the end cap 302 and the end cap 303 are fitted to the inner wall of the crushing box 2, and the top of the support rod 307 is fitted to the bottom of the baffle 202, the feed can only move out of the screening component 3 through the screen holes of the screen 301 during the crushing process. When the feed particles moving inside the screening component 3 reach a certain size, they can pass through the screen 301 and then through the crushing box 2 to enter the next process. The feed that cannot pass through the screen 301 remains inside the crusher and continues to be crushed with the movement of the crushing blade 2041 until it passes through the screen 301. Specific Implementation Example 3
[0062] Please see Figure 1-8Based on specific embodiments one and two, the air classifier 4 has a feed inlet 2 401 at its upper end. The upper end of the air classifier 4 is provided with inclined plates 1 402 and 2 403, with the bottom end of inclined plate 1 402 pointing towards the lower-middle part of inclined plate 2 403. Inside the air classifier 4, there is also an inclined plate 3 404, with the bottom end of inclined plate 2 403 pointing towards the lower-middle part of inclined plate 3 404. The air classifier 4 is positioned near inclined plate 3 404. Two air inlets 407 are opened through the inner side wall at a position lower than the bottom of the inclined plate 404. The bottom of the air separator 4 is fixedly connected to the first slope 405 and the second slope 409. The tops of the first slope 405 and the second slope 409 overlap and are lower than the air inlets 407. The bottom of the air separator 4 at the lower end of the first slope 405 is opened through the outlet 406. The bottom of the air separator 4 at the lower end of the second slope 409 is opened through the stone outlet 410.
[0063] The stone outlet 410 is connected to an external debris collection device, and the air inlet 407 is connected to an external fan.
[0064] Among them, such as Figure 1-9 As shown, the air separator 4 also includes a damper assembly 5. The damper assembly 5 includes two rotating rods 501, and the end of the rotating rod 501 away from the motor 102 passes through and extends out of the air separator 4. A baffle plate 502 is fixedly connected to the periphery of the rotating rod 501, and a belt 504 is driven to the periphery of the part of the two rotating rods 501 extending out of the air separator 4.
[0065] During the air separation process, improper air force may cause insufficient stone removal. In this case, rotating one of the rotating rods 501 will cause the other rotating rod 501 to rotate under the action of the belt 504. The baffle 502 fixed around the rotating rod 501 will also rotate around the central axis of the rotating rod 501. Since the two baffles 202 are at the same height as the two air inlets 407, the air entering from the air inlets 407 will be blocked by the baffles 202. Adjusting the position of the baffles 202 can adjust the air force to complete the air separation.
[0066] Among them, such as Figure 7-9 As shown, an arc-shaped damper adjustment groove 408 is provided on the side of the air separator 4 away from the motor 102. An adjustment handle 503 is fixedly connected to the outer side of the upper rotating rod 501 away from the air separator 4. The end of the adjustment handle 503 away from the rotating rod 501 is movably inserted into the damper adjustment groove 408.
[0067] Rotating the adjustment handle 503 will drive the rotating rod 501 and the baffle 202 to rotate. The design of the adjustment handle 503 makes it easier to adjust the wind force. The design of the damper adjustment slot 408 ensures that the adjustment handle 503 can only move along a specific trajectory, preventing damage to the adjustment handle 503 due to incorrect force direction, and making it convenient to rotate the adjustment handle 503.
[0068] The working principle of this embodiment is as follows: When performing air separation, the blower is first started, and the air blown by the blower is blown into the air separator 4 through the air inlet 407. Then, the feed to be air separated is added. The feed added from the second feed inlet 401 either moves directly along the second inclined plate 403 to the third inclined plate 404, or first moves from the first inclined plate 402 to the second inclined plate 403, and then moves to the third inclined plate 404, and then moves along the third inclined plate 404. When it moves to the bottom of the third inclined plate 404, since the air inlet 407 is lower than the bottom of the third inclined plate 404 but higher than the first inclined plate 405 and the second inclined plate 409, the feed blown in from the air inlet 407... The wind will propel lighter feed towards the first slope 405, and eventually move along the first slope 405 towards the second discharge port 406, and enter the crushing box 2 through the second discharge port 406 and the first feed port 201. Heavier stones cannot be propelled by the wind and eventually move towards the second slope 409, and move along the second slope 409 towards the stone discharge port 410, and enter the debris collection device through the stone discharge port 410. When the wind force is too strong or too weak, causing abnormal wind separation, turn the adjustment handle 503 to drive the two baffles 202 to rotate. Adjusting the position of the baffles 202 will allow the wind separation to continue to operate normally.

Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
