Description

Technical Field

[0001] This utility model is specifically a feed processing equipment with multiple protective functions. Background Technology

[0002] In recent years, driven by the livestock industry, the feed processing industry has achieved rapid development and progress, which in turn has further boosted the feed machinery industry. However, due to factors such as operational errors, installation defects, and improper maintenance during the production process, certain safety hazards exist. The following problems exist:

[0003] 1. The flywheel lacks a safety guard. If workers are not careful during work or in an emergency, their clothing may get caught in the high-speed rotating belt. Foreign objects that fall onto the belt may also be flung at workers on site, causing unnecessary injury.

[0004] 2. The lack of iron removal devices in front of key equipment means that raw materials containing metals, especially iron impurities such as screws, washers, and iron blocks, may enter the crusher during the feed processing equipment's conveying process. This can cause minor damage to the screen and hammer blades, or even directly puncture the machine body, posing a direct threat to the safety of the workers.

[0005] 3. The small feed inlet does not have a dust cover. The small feed inlet contains some fine raw materials, such as mineral additives and vitamin additives. Before these raw materials enter the mixer, dust can easily be generated and absorbed by the human body. Long-term inhalation of large amounts can cause discomfort symptoms such as chest tightness, dizziness, and nausea, and in severe cases, it can affect health. Utility Model Content

[0006] In view of the above, this utility model provides a feed processing equipment with multiple protective functions to solve the problems mentioned in the background art.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: a feed processing equipment with multiple protection functions, including a main frame of the equipment, a crusher, a pellet mill and a transmission mechanism, as well as a flywheel and a pulley installed on the main frame of the equipment, and a small material inlet for adding fine raw materials is provided on the main frame of the equipment. It also includes: a safety protection component, which is composed of a metal grid cover surrounding the flywheel and the pulley. The grid cover has honeycomb-shaped ventilation holes and an infrared sensor is provided on the inner side. The infrared sensor is linked to the emergency stop switch of the transmission mechanism; an iron removal component, including an electromagnetic iron remover and a metal detector arranged sequentially along the material conveying direction. The electromagnetic iron remover is installed on the inclined section of the crusher feed hopper, and a pneumatic baffle assembly is provided at the inlet of the pellet mill. The metal detector is located at the inlet of the pellet mill, and the metal detector and the pneumatic baffle assembly are electrically connected to form a linkage locking mechanism; a dustproof feeding mechanism, including a pneumatic flap with a weighing module. The pneumatic flap is movably connected to the small material inlet of the main frame of the equipment via a rotating shaft.

[0008] Preferably, the mesh diameter of the metal grille cover is ≤5mm, and the metal grille cover is detachably installed on the periphery of the flywheel and pulley via connectors.

[0009] Preferably, the pneumatic baffle assembly includes a baffle and a pneumatic telescopic rod. The pneumatic telescopic rod is connected to the baffle and is located at the inlet of the granulator. The metal detector is connected to the input end of the pneumatic telescopic rod.

[0010] Preferably, it also includes a magnetic switch, which causes the pneumatic flap to be attracted and closed at the small material inlet, and the weighing module is connected to the input end of the magnetic switch.

[0011] Preferably, when the pneumatic flap closes at the material inlet, the gap between the pneumatic flap and the material inlet is ≤0.5mm.

[0012] The feed processing equipment of this utility model, by installing a metal grid cover surrounding the flywheel and pulley, prevents the flywheel from getting caught in the workers' clothing in the high-speed rotating belt, causing unnecessary injury. In addition, it is equipped with an infrared sensor that can automatically open the emergency stop switch to stop the flywheel from working in case of an accident, thus preventing further injury.

[0013] By installing iron removal components, adding iron removal equipment after raw material cleaning, before crushing, and before granulation, damage and danger caused by iron impurities entering the main equipment can be effectively prevented.

[0014] By setting up a dust-proof feeding mechanism and installing a pneumatic flap at the small material inlet, it is possible to easily add fine raw materials, such as mineral additives and vitamin additives, while also preventing dust from spreading. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and some embodiments.

[0022] exist Figures 1-5 A feed processing device with multiple protective functions includes a main frame 1, a crusher 2, a pellet mill 3, and a transmission mechanism, as well as a flywheel and pulley mounted on the main frame 1. The main frame 1 is provided with a small material inlet 10 for adding fine raw materials. It also includes a safety protection component consisting of a metal grid cover 4 surrounding the flywheel and pulley. The grid cover has honeycomb-shaped ventilation holes and an infrared sensor 5 is installed inside. The infrared sensor 5 is linked to the emergency stop switch of the transmission mechanism. By installing the metal grid cover 4 surrounding the flywheel and pulley, the device prevents the flywheel from entangled in the worker's clothing, causing unnecessary injury. Furthermore, the infrared sensor 5 generates a sensing signal when an object gets caught in the flywheel and pulley, transmitting it to the emergency stop switch of the transmission mechanism to stop the transmission mechanism and immediately stop the flywheel, preventing further injury.

[0023] In this embodiment, the iron removal assembly includes an electromagnetic iron separator 7 and a metal detector 8 arranged sequentially along the material conveying direction. The electromagnetic iron separator 7 is installed on the inclined section of the feed hopper of the crusher 2, and a pneumatic baffle 11 assembly is provided at the inlet of the granulator 3. The metal detector 8 is located at the inlet of the granulator 3, and the metal detector 8 and the pneumatic baffle 11 assembly are electrically connected to form a linkage locking mechanism. The pneumatic baffle 11 assembly includes a baffle 11 and a pneumatic telescopic rod 9. The pneumatic telescopic rod 9 is connected to the baffle 11 and located at the inlet of the granulator 3, and the metal detector 8 is connected to the input end of the pneumatic telescopic rod 9. First, when raw materials are added into the crusher 2 through the feed hopper, the magnetic attraction force generated by the electromagnetic iron separator 7 will remove iron from the raw materials. The iron impurities are adsorbed to prevent them from entering the pulverizer 2 and causing damage or serious consequences. Secondly, the metal detector 8 performs secondary metal detection on the pulverized raw material. When iron impurities are detected, an abnormal detection signal is generated and transmitted to the pneumatic telescopic rod 9, causing the pneumatic telescopic rod 9 to actuate and close the baffle 11 at the entrance of the pellet mill 3, intercepting the raw material with residual iron impurities. This allows for manual screening by staff to remove the residual iron impurities. After the baffle 11 is opened, the raw material continues to enter the pellet mill 3. The gradient iron removal process can effectively prevent iron impurities from mixing into the feed, avoiding feed quality problems that could affect subsequent sales and use.

[0024] In this embodiment, the dust-proof feeding mechanism includes a pneumatic flap 12 with a weighing module 15. The pneumatic flap 12 is movably connected to the small material inlet 10 of the main frame 1 of the equipment via a rotating shaft 13. It also includes a magnetic switch 14, which causes the pneumatic flap 12 to be attracted and closed at the small material inlet 10. The weighing module 15 is connected to the input end of the magnetic switch 14. When the main body of the equipment is working normally, the magnetic switch 14 causes the pneumatic flap 12 to be attracted and closed at the small material inlet 10. When it is necessary to add fine raw materials, such as mineral additives, vitamin additives, etc., the raw materials are placed on the pneumatic flap 12. The weighing module 15 can be set to a weight of 3kg. If the weight of the placed raw materials exceeds 3kg, the weighing module 15 generates a setting signal and transmits it to the magnetic switch 14, causing the magnetic switch 14 to close. The pneumatic flap 12 is then flipped open via the rotating shaft 13, allowing the placed raw materials to enter the small material inlet 10. This not only facilitates the addition of fine raw materials, such as mineral additives, vitamin additives, etc., but also prevents dust from spreading. In this embodiment, the set weight of the weighing module 15 can be adjusted, with 3kg as the base set weight.

[0025] In this embodiment, the mesh diameter of the metal grille cover 4 is ≤5mm. The metal grille cover 4 is installed on the periphery of the flywheel and pulley by means of screws. The metal grille cover 4 prevents items from entering the flywheel and belt, causing unnecessary damage, and the screw-removable installation makes maintenance and replacement convenient.

[0026] In this embodiment, when the pneumatic flap 12 is closed at the material inlet 10, the gap between the pneumatic flap 12 and the material inlet 10 is ≤0.5mm; this prevents raw materials inside the equipment body from leaking out through the gap between the pneumatic flap 12 and the material inlet 10, thus avoiding pollution.

[0027] In this embodiment, the model of the electromagnetic separator 7 is not particularly limited. It can be a dry electromagnetic separator, a self-unloading electromagnetic separator, etc., but it is preferred to be an RCDB series dry electromagnetic separator, an RCDD series self-unloading electromagnetic separator, etc. Other models can also be selected in actual applications, and no restrictions are imposed here.

[0028] In this embodiment, the model of the metal detector 8 is not particularly limited. It can be a conveyor belt metal detector or a pipeline metal detector, but it is preferred to be a GJT series conveyor belt metal detector or an MD series pipeline metal detector. Other models can also be selected in actual applications, and no restrictions are imposed here.

[0029] In this embodiment, the model of the pneumatic telescopic rod 9 is not particularly limited. It can be a common telescopic rod device, but it is preferred to be the WSD50-100 model, WSD120-300-A model, etc. Other models can also be selected in actual applications, and there are no restrictions here.

[0030] In this embodiment, the model of the weighing module 15 is not particularly limited. It can be a common weighing sensor device, but it is preferred to be the MM SS1100AC model, LS21-28MR-2WT model, etc. Other models can also be selected in actual applications, and there are no restrictions here.

[0031] In specific implementation of this utility model: First, when raw materials are added into the pulverizer 2 through the feed hopper, the magnetic attraction generated by the electromagnetic iron separator 7 will adsorb iron impurities in the raw materials, preventing iron impurities from entering the pulverizer 2 and causing damage to it; Second, the metal detector 8 performs secondary metal detection on the pulverized raw materials, and can be closed at the inlet of the pellet mill 3 by the baffle 11 to intercept the raw materials with residual iron impurities, so that the staff can manually screen them. The gradient iron removal process can effectively intercept iron impurities from mixing into the feed, avoiding problems with feed quality and affecting subsequent sales and use; When the raw materials are placed on the pneumatic flip plate 12, when the weight of the placed raw materials exceeds the set weight of the weighing module 15, the magnetic attraction switch 14 closes, and the pneumatic flip plate 12 flips open through the rotating shaft 13, allowing the placed raw materials to enter the small material inlet 10; The metal grid cover 4 prevents the flywheel from getting the staff's clothing into the high-speed rotating belt, causing unnecessary injury.
