Description

Technical Field

[0001] The utility model belongs to the technical field of feed processing, and particularly relates to an anti-overflow safety cover for a feed crusher. Background Art

[0002] Feed is the general term for the food of all animals raised. It mainly refers to the food of animals raised in agriculture or animal husbandry. The feed used to feed livestock and poultry needs to be pulverized from feed raw materials. A feed crusher is a device used to pulverize feed.

[0003] Among them, through retrieval, it is found that there is an application number CN202022833734.1, which discloses a feed crusher, including a bottom plate. The upper surface of the bottom plate is fixedly connected with a crusher body. By setting a universal pipe in cooperation with a first rotating rod, a second rotating rod, a push rod and a push handle, the push handle is pushed to drive the push rod to push the second rotating rod and the first rotating rod to rotate, thereby driving the discharge pipe to rotate, avoiding the situation that too much feed accumulates at the outlet of the feed crusher, affecting the discharge, thus reducing the working intensity of the user and increasing the working efficiency of the user. By setting a motor bracket, it is convenient to fix the driving motor, and when the driving motor is damaged, it is convenient to replace the driving motor. By setting a filter mesh cover made of metal material, when pulverizing and filtering straw feed, the pulverized feed splashes into the driving motor, affecting the operation of the driving motor. By setting a feed hopper, it is convenient to feed. By setting a rubber sleeve, the friction of the push handle is increased, facilitating the use of the push handle to push the push rod. By setting universal wheels, it is convenient to move the device.

[0004] However, through research, it is found that: this device does not have an anti-overflow structure. During the pulverization process, the feed accumulated inside the crusher is likely to overflow from the crusher inlet, causing waste and blocking the crusher inlet at the same time. This device does not have a structure for packaging and sealing the pulverized feed. There is a large amount of pulverized feed, which is not easy to store, and subsequent separate packaging is required, resulting in low working efficiency. Therefore, a new device is provided to solve this problem. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-overflow safety cover for a feed crusher to solve the problems of the above-mentioned lack of anti-overflow structure and lack of structure for packaging and sealing the feed.

[0006] The technical solution adopted by the utility model is as follows: an anti-overflow safety cover for a feed crusher, including a support frame, and a pulverization tank is fixedly installed on one side above the support frame;

[0007] A feed pulverization mechanism with an anti-overflow function is arranged above the support frame.

[0008] Among them, the feed crushing mechanism includes a crushing roller A, a crushing roller B, a motor, a feed trough, a discharge valve A, a guide plate, a connecting rod, and a microswitch. On both sides inside the crushing trough, a crushing roller A and a crushing roller B are rotatably connected by a motor respectively. Above the support frame, a feed trough is embedded and installed, and the outlet of the feed trough extends into the crushing trough. A discharge valve A is installed at the outlet of the feed trough. One side of the inlet of the crushing trough is rotatably connected by a rotating shaft with a guide plate, and the guide plate is arc-shaped and elastically connected to the inside of the crushing trough through a spring. A convex block is arranged on the outer side of the guide plate. One side inside the crushing trough is fixedly installed with a connecting rod, and one end of the connecting rod is installed with a microswitch.

[0009] Among them, a screw conveyor is vertically and fixedly installed above the support frame, and the outlet of the crushing trough is connected to the inlet of the screw conveyor. Above the support frame, a stirring trough is fixedly installed, and the outlet of the screw conveyor extends into the stirring trough. A stirrer is vertically installed inside the stirring trough. A scraper is installed on one side of the stirrer through a stirring paddle, and the scraper is in contact with the inner wall of the stirring trough.

[0010] Among them, a discharge valve B is installed at the outlet of the stirring trough. The outlet of the discharge valve B is connected with a feeding pipe, and the feeding pipe is telescopically arranged. One side of the outlet of the stirring trough is installed with a servo electric cylinder, and the end of the servo electric cylinder is in contact with the feeding pipe. The middle part above the support frame is rotatably connected with a connecting disk through a servo turntable. The outer circumference of the connecting disk is equidistantly and circumferentially fixedly installed with support plates, and the number of support plates is six. A limiting plate is fixedly installed on one side above the support plate, and the limiting plate is arc-shaped. Ball bearings are symmetrically and rotatably embedded above the support plate. A conveyor belt is installed on the other side above the support frame. A cross frame is fixedly installed at the position corresponding to the conveyor belt above the support frame. A sealing groove is fixedly installed below the cross frame. Temperature control electric heating plates are symmetrically and embeddedly installed on both sides inside the sealing groove.

[0011] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0012] 1. In the present utility model, through the feed crushing mechanism, when the feed raw materials above the crushing roller A and the crushing roller B accumulate too much, the feed raw materials squeeze the guide plate to rotate, and the convex block on one side of the guide plate collides with the microswitch. The microswitch controls the discharge valve A to suspend operation and stop feeding the feed raw materials into the crushing trough, avoiding excessive addition of feed raw materials into the crushing trough and causing overflow, and at the same time avoiding blockage of a large amount of feed raw materials at the inlet of the crushing trough.

[0013] 2. In the present utility model, when the servo electric cylinder extends, it pushes the blanking pipe downward to the corresponding packaging bag. The discharge valve B discharges the feed inside the mixing tank into the packaging bag on the corresponding support plate. When the feed filled in the packaging bag approaches the entrance of the packaging bag, the servo turntable drives the connecting plate to rotate by 60°, so that the next support plate in sequence moves to the outlet of the mixing tank to fill another packaging bag. The six support plates work alternately to continuously discharge and package the feed inside the mixing tank, improving the working efficiency.

[0014] 3. In the present utility model, when the support plate corresponding to the packaging bag filled with feed rotates to be parallel to the conveyor belt, the staff pulls the packaging bag on this support plate and pulls it onto the conveyor belt. The balls reduce the friction between the packaging bag and the support plate, making the movement of the packaging bag smoother. The conveyor belt works to convey the packaging bag filled with feed. The staff assists in passing the bag mouth of the packaging bag through the sealing grooves. The two temperature-controlled electric heating plates are in a high-temperature state to heat-seal the bag mouth of the passing packaging bag, achieving the purpose of discharging and sealing the feed bag.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] In the present invention:

[0022] Referring to Figures 1-4 , an anti-overflow safety guard for a feed crusher, which includes a support frame 1, and a crushing groove 2 is fixedly installed on one side above the support frame 1;

[0023] A feed crushing mechanism with an anti-overflow function is arranged above the support frame 1.

[0024] Referring to Figures 1-3 , in this embodiment, the feed crushing mechanism includes a crushing roller A 201, a crushing roller B 2011, a motor 2012, a feed trough 202, a discharge valve A 2021, a guide plate 2022, a connecting rod 203 and a microswitch 2031. The crushing roller A 201 and the crushing roller B 2011 are respectively rotatably connected to both sides inside the crushing groove 2 through the motor 2012. The feed trough 202 is embedded and installed above the support frame 1, and the outlet of the feed trough 202 extends into the crushing groove 2. A discharge valve A 2021 is installed at the outlet of the feed trough 202. One side of the inlet of the crushing groove 2 is rotatably connected to the guide plate 2022 through a rotating shaft, and the guide plate 2022 is arc-shaped and elastically connected to the inside of the crushing groove 2 through a spring, and a convex block is arranged on the outer side of the guide plate 2022. A connecting rod 203 is fixedly installed on one side inside the crushing groove 2, and a microswitch 2031 is installed at one end of the connecting rod 203;

[0025] Staff members regularly pour a variety of feed raw materials into the inside of the feed trough 202, and then close the sealed cover plate at the entrance of the feed trough 202. The discharge valve A2021 works, continuously conveying the raw materials inside the feed trough 202 downward. The raw materials fall to the gap between the crushing roller A201 and the crushing roller B2011. Two motors 2012 drive the crushing roller A201 and the crushing roller B2011 to rotate in opposite directions, conveying the raw materials between the crushing roller A201 and the crushing roller B2011 downward, and at the same time squeezing and shearing the passing feed to achieve the purpose of crushing the feed raw materials. When the feed raw materials above the crushing roller A201 and the crushing roller B2011 accumulate too much, the feed raw material extrusion guide plate 2022 rotates, and the convex block on one side of the guide plate 2022 collides with the microswitch 2031. The microswitch 2031 controls the discharge valve A2021 to pause working and stop conveying feed raw materials into the crushing tank 2, so as to avoid overflow caused by adding too much feed raw materials into the crushing tank 2. Until all the feed accumulated above the crushing roller A201 and the crushing roller B2011 is conveyed downward and crushed, the guide plate 2022 loses the pressure of the feed, and under the action of the spring, the guide plate 2022 rebounds, the convex block moves away from the microswitch 2031, and the discharge valve A2021 continues to work, conveying feed raw materials into the crushing tank 2.

[0026] Refer to Figures 1-2 In this embodiment, a screw conveyor 204 is vertically and fixedly installed above the support frame 1, and the outlet of the crushing tank 2 is connected to the inlet of the screw conveyor 204. A stirring tank 3 is fixedly installed above the support frame 1, and the outlet of the screw conveyor 204 extends into the inside of the stirring tank 3. A stirrer 301 is vertically installed inside the stirring tank 3. A scraper 3011 is installed on one side of the stirrer 301 through a stirring paddle, and the scraper 3011 is in contact with the inner wall of the stirring tank 3;

[0027] The crushed feed inside the crushing tank 2 falls from the outlet of the crushing tank 2 into the inside of the screw conveyor 204. The motor supporting the screw conveyor 204 drives the supporting screw conveyor rod to rotate, conveying the feed inside the screw conveyor 204 upward into the inside of the stirring tank 3. The stirrer 301 works to stir the feed inside the stirring tank 3 to make it evenly mixed. While the stirrer 301 is working, the scraper 3011 continuously scrapes across the inner wall of the stirring tank 3, scraping off the feed adhering to the inner wall of the stirring tank 3 to avoid waste caused by the feed adhering to the inner wall of the stirring tank 3.

[0028] Refer to Figures 1-2 In this embodiment, a discharge valve B302 is installed at the outlet of the stirring tank 3. A discharge pipe 3021 is connected to the outlet of the discharge valve B302, and the discharge pipe 3021 is telescopically arranged. A servo electric cylinder 3022 is installed on one side of the outlet of the stirring tank 3, and the end of the servo electric cylinder 3022 is in contact with the discharge pipe 3021;

[0029] During discharging, the servo electric cylinder 3022 extends, pushing the blanking pipe 3021 downward into the receiving container, and the discharging valve B302 discharges the feed inside the mixing tank 3.

[0030] Referring to Figures 1-2 , in this embodiment, a connection disk 101 is rotatably connected to the middle of the upper part of the support frame 1 through a servo turntable 1011. A plurality of support plates 102 are fixedly installed around the outer circumference of the connection disk 101 at equal intervals. The number of the support plates 102 is six. A limiting plate 1021 is fixedly installed on one side above the support plate 102, and the limiting plate 1021 is arc-shaped.

[0031] Workers respectively put packaging bags on the outside of the six arc-shaped limiting plates 1021. The servo turntable 1011 drives the connection disk 101 to rotate, so that a support plate 102 just rotates to the outlet of the mixing tank 3. The discharging valve B302 discharges the feed inside the mixing tank 3 into the packaging bag on the corresponding support plate 102. When the feed in the packaging bag is close to the entrance of the packaging bag, the discharging valve B302 pauses working. The servo turntable 1011 drives the connection disk 101 to rotate 60°, so that another support plate 102 in sequence rotates to the position corresponding to the outlet of the mixing tank 3. The discharging valve B302 continues to work and imports feed into another packaging bag. In this way, the six support plates 102 work alternately, continuously discharging and packaging the feed inside the mixing tank 3.

[0032] Referring to Figure 1 , 2 , 4, in this embodiment, a conveyor belt 103 is installed on the other side above the support frame 1. A cross frame 104 is fixedly installed at the position corresponding to the conveyor belt 103 above the support frame 1. A sealing groove 1041 is fixedly installed below the cross frame 104. Two temperature-controlled electric heating plates 1042 are symmetrically embedded and installed on both sides inside the sealing groove 1041. Two balls 1022 are symmetrically embedded and rotatably connected above the support plate 102.

[0033] When the support plate 102 corresponding to the packaging bag filled with feed rotates to be parallel to the conveyor belt 103, the worker pulls the packaging bag on the support plate 102 and pulls it onto the conveyor belt 103. The balls 1022 reduce the friction between the packaging bag and the support plate 102, making the movement of the packaging bag smoother. The conveyor belt 103 works to convey the packaging bag filled with feed. The worker assists to pass the bag mouth of the packaging bag through between the sealing grooves 1041. The two temperature-controlled electric heating plates 1042 are in a high-temperature state and heat-seal the bag mouth of the passing packaging bag by hot melting, achieving the purpose of discharging and sealing the feed bag. Then, a new packaging bag is put on the outside of the idle limiting plate 1021.

[0034] Referring to Figures 1-4, in this embodiment, the servo turntable 1011, the conveyor belt 103, the temperature-controlled electric hot plate 1042, the motor 2012, the discharge valve A 2021, the microswitch 2031, the screw conveyor 204, the stirrer 301, the discharge valve B 302, and the servo electric cylinder 3022 are all electrically connected to an external power supply through a switch panel, and the discharge valve A 2021 is electrically connected to the external power supply through the microswitch 2031.

[0035] Working principle: First, the staff regularly pour various feed raw materials into the inside of the feed trough 202, then close the sealing cover plate at the inlet of the feed trough 202, and then the discharge valve A2021 works, continuously conveying the raw materials inside the feed trough 202 downward. The raw materials fall to the gap between the crushing roller A201 and the crushing roller B2011. Two motors 2012 drive the crushing roller A201 and the crushing roller B2011 to rotate in opposite directions, conveying the raw materials between the crushing roller A201 and the crushing roller B2011 downward, and at the same time squeezing and shearing the passing feed to achieve the purpose of crushing the feed raw materials. The crushed feed falls from the outlet of the crushing tank 2 into the inside of the screw conveyor 204. The motor supporting the screw conveyor 204 drives the supporting screw conveyor rod to rotate, conveying the feed inside the screw conveyor 204 upward into the stirring tank 3. When the feed raw materials above the crushing roller A201 and the crushing roller B2011 accumulate too much, the feed raw materials squeeze the guide plate 2022 to rotate. The convex block on one side of the guide plate 2022 collides with the microswitch 2031, and the microswitch 2031 controls the discharge valve A2021 to pause working and stop conveying feed raw materials into the crushing tank 2 to avoid overflow caused by adding too much feed raw materials into the crushing tank 2. Until all the feed accumulated above the crushing roller A201 and the crushing roller B2011 is conveyed downward and crushed, the guide plate 2022 loses the pressure of the feed, and under the action of the spring, the guide plate 2022 rebounds, the convex block moves away from the microswitch 2031, and the discharge valve A2021 continues to work, conveying feed raw materials into the crushing tank 2. Then the stirrer 301 works to stir the feed inside the stirring tank 3 to make it evenly mixed. While the stirrer 301 is working, the scraper 3011 continuously scrapes across the inner wall of the stirring tank 3 to scrape off the feed adhered to the inner wall of the stirring tank 3 to avoid waste caused by the feed adhering to the inner wall of the stirring tank 3. After that, the staff respectively put packaging bags on the outside of the six arc-shaped limiting plates 1021. The servo turntable 1011 drives the connecting plate 101 to rotate, so that a support plate 102 just rotates to the outlet of the stirring tank 3. The servo electric cylinder 3022 extends, pushing the feeding pipe 3021 to move down into the corresponding packaging bag. The discharge valve B302 discharges the feed inside the stirring tank 3 into the packaging bag on the corresponding support plate 102. When the feed contained in the packaging bag is close to the inlet of the packaging bag, the discharge valve B302 pauses working. The servo turntable 1011 drives the connecting plate 101 to rotate 60°, so that another support plate 102 in sequence rotates to correspond to the outlet of the stirring tank 3. The discharge valve B302 continues to work and imports feed into another packaging bag. And so on. Finally, when the support plate 102 corresponding to the packaging bag containing feed rotates to be parallel to the conveyor belt 103, the staff pull the packaging bag on this support plate 102 and pull it onto the conveyor belt 103. The ball 1022 reduces the friction between the packaging bag and the support plate 102, making the movement of the packaging bag smoother. The conveyor belt 103 works to convey the packaging bag containing feed.The staff assist to pass the bag mouth of the packaging bag through between the sealing grooves 1041. The two temperature-controlled electric heating plates 1042 are in a high-temperature state and heat-seal the passing bag mouth of the packaging bag, so as to achieve the purpose of discharging and sealing the feed bag. Then, a new packaging bag is put on the outside of the idle limiting plate 1021. The six support plates 102 work alternately to continuously export and package the feed in the stirring tank 3.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
