Description

Technical Field

[0001] The invention relates to the technical field of feed mixing, in particular to a feed mixing device. Background Art

[0002] Feed is the general term for food for animals raised by all people. In a narrower sense, general feed mainly refers to food for animals raised in agriculture or animal husbandry. In order to increase the nutritional content of feed, fish meal, vitamins, minerals and other nutrients (i.e. fine materials) need to be added to the main body of the feed during the production process. When adding these nutrients, a feed mixing device is needed to mix the feed and the nutrients. When mixing the feed and the nutrients, the feed mixing device needs to add the nutrients and the feed base material with a good ratio into a container in advance, and then mix the nutrients and the feed base material through a stirring paddle, and finally take the mixed feed out of the feed mixing device; Existing feed mixing devices generally use a motor to drive a stirring paddle to mix the feed, which does not mix the feed evenly, has a poor mixing effect on corners, and easily produces dead corners, thereby affecting the quality of feed products and production and processing efficiency. In addition, simply mixing the feed with a stirring paddle takes a long time.

[0003] For example, the Chinese authorized patent with announcement number CN 220737319 U (a feed mixing device): when the device mixes multiple feeds, it only needs to pour the feed into the corresponding feed hopper, and the feed flows from the feed hopper into the mixing bin, and before that, the outlet of the mixing bin is closed by the regulating device. When the feed flows into the mixing bin, the vibrator starts to work in this process, and under the action of the vibrator, the multiple feeds are preliminarily mixed in the mixing bin, and the preliminarily mixed feed flows into the mixing bin for sufficient mixing. This technical solution solves the above problems; However, the technical solution of the invention still has some technical problems. When the feed mixing device is used, the staff needs to mix the feed base material and the fine materials in advance and then add them into the barrel, which requires a long time of material preparation when the feed mixing device is used. At the same time, when the feed base material and the fine materials are mixed in the mixing barrel, the stirring paddle needs to mix all the feed base material and the fine materials added into the mixing barrel at one time. The mixing intensity is relatively large, which results in a long mixing cycle of the feed base material and the fine materials. Summary of the invention

The installation of the spiral conveying and mixing bracket 20 can transport feed base materials and fine materials, so that the feed base materials and fine materials can move stably inside the device. Since the outer surface of the spiral conveying and mixing bracket 20 is relatively smooth, when the spiral conveying and mixing bracket 20 rotates, several disturbing mixing shafts 21 outside the spiral conveying and mixing bracket 20 will perform impact stirring and mixing on the feed base materials and fine materials. At the same time, since the spiral conveying and mixing bracket 20 rotates continuously, and the staff adjusts the material discharge control valves 6 at the lower ends of the four material filling barrels 2 to achieve the discharge amount of feed base materials and fine materials per unit time, thereby making the amount of feed base materials and fine materials entering the feed mixing barrel 1 per unit time constant, and the spiral conveying and mixing bracket 20 is stable. The mixing bracket 20 rotates continuously, and the amount of feed base material and fine materials transported per unit time is constant, so that the spiral conveying mixing bracket 20 can mix the feed base material and fine materials while transporting them, and there is no need for the staff to mix the feed base material and fine materials in advance, so that the device does not need to prepare materials for a long time when in use, and at the same time ensures that the mixed feed is continuously discharged from the inside of the device, avoiding a large amount of feed base material and fine materials being mixed at the same time, so that the mixed feed products are discharged from the device at the same time, and preventing the feed mixing device from not working effectively during the material preparation stage and the discharge stage. A plurality of disturbing mixing shafts 21 are fixedly installed on the upper end of the outer portion of the spiral conveying mixing bracket 20, four material filling cylinders 2 are installed above the feed mixing cylinder 1, and a material discharge control valve 6 is fixedly installed at the lower end of the material filling cylinder 2; The support bracket 3 is fixedly installed on the upper end between the four material filling cylinders 2, and the vibration transmission bracket 15 is fixedly installed on the lower end between the four material filling cylinders 2.

[0021] See also Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 A connecting portion 30 is provided at the upper end of the hollow transmission shaft 19, and the connecting portion 30 and the hollow transmission shaft 19 are arranged to form an integrally formed structure. An isolation net 22 is fixedly installed on the outside of the hollow transmission shaft 19. The installation of the isolation net 22 can prevent feed base materials and fine materials from entering the interior of the hollow transmission shaft 19, while ensuring that air can be blown into the interior of the feed mixing barrel 1, thereby enhancing the practicality of the device. An air blowing bracket 9 is installed on the outside of the connecting portion 30, and the air blowing bracket 9 is rotatably connected to the hollow transmission shaft 19 through a bearing. A connecting pipe 17 is fixedly installed on one side of the air blowing bracket 9, and an air blowing fan 10 is fixedly installed on one end of the connecting pipe 17. The air blowing fan 10 blows air into the air blowing bracket 9 through the connecting pipe 17, and the air blowing bracket 9 rotates outside the hollow transmission shaft 19, so that air passes through the air blowing bracket 9 and enters the interior of the hollow transmission shaft 19, and then the air is blown out through the isolation net 22 outside the hollow transmission shaft 19. At the upper end of the feed matrix and the fine materials, the fine materials are moved under the action of the airflow, so that the fine materials are fully in contact with the feed matrix. At the same time, when the air is blown into the feed mixing cylinder 1, the air blows up the small amount of feed products remaining in the feed mixing cylinder 1, so that the feed can be discharged from the feed mixing cylinder 1 more smoothly. A return pipe 16 is fixedly installed on one side of the upper end of the feed mixing cylinder 1. The return pipe 16 is fixedly connected to the air inlet end of the air blowing fan 10.

A second solenoid valve 29 is fixedly installed on the upper end of the return pipe 16. The return pipe 16 cooperates with the switch of the second solenoid valve 29 to make the air carrying a small amount of fine materials discharged from the feed mixing cylinder 1 flow back into the feed mixing cylinder 1, so as to prevent these fine materials from being discharged to the outside and causing the loss of fine materials.

[0022] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9A mounting bracket 8 is installed at the lower end of the air blowing fan 10, and the mounting bracket 8 is connected to the air blowing fan 10 by screws. The mounting bracket 8 is welded to the feed mixing barrel 1. A strength reinforcement plate 18 is installed inside the feed mixing barrel 1, and the strength reinforcement plate 18 is fixedly connected to the feed mixing barrel 1. A bottom bracket 12 is installed at the lower end of the outside of the feed mixing barrel 1, and the bottom bracket 12 is welded to the feed mixing barrel 1. A control box 11 is installed at the front end surface of the outside of the feed mixing barrel 1, and the control box 11 is connected to the feed mixing barrel 1 by screws. A stable bracket 26 is installed at the lower end of the inside of the feed mixing barrel 1, and the stable bracket 26 is welded to the feed mixing barrel 1. The upper end surface of the stable bracket 26 is set to a slope structure, which is convenient for assisting the feed discharging device. The stable bracket 26 is rotatably connected to the hollow transmission shaft 19 through a bearing, and the hollow transmission shaft 19 is connected to the support bracket 3 through The bearing is rotatably connected, and a discharge plate 13 is installed on the lower end surface of the feed mixing barrel 1. Installing the discharge plate 13 allows the staff to selectively seal the lower end of the device, so that the device can simultaneously mix the traditional feed matrix and fine materials, and can also perform efficient mixing and discharging at the same time, so that the device can be more flexible according to different usage requirements. The discharge plate 13 is rotatably connected to the feed mixing barrel 1 through a clamping shaft, and a convenient handle 14 is welded to the front end surface of the discharge plate 13. A drive motor 4 is installed on the upper end surface of the support bracket 3 through screws, and the drive motor 4 is connected to the hollow transmission shaft 19 through a coupling. A connecting hose 7 is installed at the lower end of the material discharge control valve 6, and the connecting hose 7 is fixedly connected to the material discharge control valve 6. Four support rods 5 are installed at the lower end of the support bracket 3, and the four support rods 5 are welded to the support bracket 3 and the feed mixing barrel 1.

[0023] Working principle: When in use, the device has two usage modes, the traditional feed matrix and fine materials are mixed at the same time mode: the staff adds the feed matrix and fine materials into the material filling cylinder 2, and at the same time the staff holds the convenient handle 14 to rotate the rotary discharge plate 13, so that the rotary discharge plate 13 is located at the lower end of the feed mixing cylinder 1, and then the rotary discharge plate 13 seals the lower end of the feed mixing cylinder 1. At this time, the feed matrix and fine materials are added to the feed mixing cylinder 1 through the material filling cylinder 2, the material discharge control valve 6 and the connecting hose 7, and then the material discharge control valve 6 is closed, so that the inside of the device is sealed, and then the driving motor 4 drives the hollow transmission shaft 19 to rotate counterclockwise, so that the spiral conveying mixing bracket 20 continuously adds the feed matrix and fine materials. The material is transported to the upper end of the feed mixing barrel 1. Since the upper end of the spiral conveying mixing bracket 20 is not a planar structure, the spiral conveying mixing bracket 20 drives the feed matrix and the fine materials to turn over. At the same time, the disturbing mixing shaft 21 outside the spiral conveying mixing bracket 20 stirs and mixes the feed matrix and the fine materials. At this time, the first solenoid valve 28 is closed, and the second solenoid valve 29 is opened. The air blowing fan 10 sucks out the air inside the feed mixing barrel 1 through the return pipe 16, and then blows it into the hollow transmission shaft 19. Then, the air is blown onto the upper end of the feed matrix and the fine materials through the isolation net 22, so that the air circulates inside the device, and then the feed matrix and the fine materials are mixed under the dual effects of the airflow and the disturbing mixing shaft 21. After the feed is mixed, , the staff opens the discharge plate 13, closes the second solenoid valve 29, opens the first solenoid valve 28, and drives the driving motor 4 to drive the hollow transmission shaft 19 to rotate instantaneously, so that the spiral conveying mixing bracket 20 discharges the feed from the device, and the air blowing fan 10 sucks the outside air into the feed mixing cylinder 1 through the air inlet and outlet pipes 27, so that the outside air blows the feed to move, and assists the smooth discharge of the feed from the device; Continuous and efficient mixing mode: the staff opens the discharge plate 13, and then the staff adds the feed matrix and fine materials into the material filling cylinder 2, and at the same time adjusts the material discharge control valve 6 to the feed matrix and fine materials per unit time. The amount of passing through the unit time of the feed matrix and fine materials, and then the driving motor 4 drives the hollow transmission shaft 19 to rotate quickly instantaneously, so that the hollow transmission shaft 19 with The dynamic spiral conveying and mixing bracket 20 transports the feed matrix and fine materials downward. Since the amount of the feed matrix and fine materials entering the feed mixing barrel 1 per unit time is constant, the stability of the ratio of the feed matrix and fine materials is ensured, and the spiral conveying and mixing bracket 20 rotates continuously, and the amount of the feed matrix and fine materials transported per unit time is constant. The outer surface of the spiral conveying and mixing bracket 20 is smooth, so that the spiral conveying and mixing bracket 20 cooperates with the disturbing mixing shaft 21 to transport and mix the feed matrix and fine materials. The device continuously mixes the feed matrix and fine materials that continuously enter the device, so that the mixed feed is continuously discharged from the device, which can ensure that the staff can continuously collect the feed efficiently and reduce the instantaneous mixing intensity of the device.The entire spiral conveying and mixing bracket 20 can evenly mix the feed base material and the fine materials, and the feed base material and the fine materials are evenly distributed on the outside of the spiral conveying and mixing bracket 20, thereby reducing the instantaneous pressure on the staff to collect the feed, avoiding the problem that a large amount of feed is discharged within a period of time and the staff cannot collect the feed quickly. At the same time, the staff does not need to mix the feed base material and the fine materials in advance, and only needs to adjust the material discharge control valve 6 once, and only needs to keep adding the feed base material and the fine materials afterwards, which greatly improves the effective utilization rate of the device, ensures that the feed mixing production is carried out efficiently, and shortens the mixing cycle of the feed base material and the fine materials. The device is equipped with a spiral conveying and mixing bracket 20 to transport the feed base material and the fine materials. The feed base material and fine materials are stably moved inside the device. Since the outer surface of the spiral conveying and mixing bracket 20 is relatively smooth, when the spiral conveying and mixing bracket 20 rotates, several disturbing and mixing shafts 21 outside the spiral conveying and mixing bracket 20 will perform impact stirring and mixing on the feed base material and fine materials. At the same time, since the spiral conveying and mixing bracket 20 rotates continuously, and the staff adjusts the material discharge control valves 6 at the lower ends of the four material filling cylinders 2 to achieve the discharge amount of the feed base material and fine materials per unit time, thereby making the amount of the feed base material and fine materials entering the feed mixing cylinder 1 per unit time constant, and the spiral conveying and mixing bracket 20 rotates continuously, and the amount of the feed base material and fine materials transported per unit time is constant, thereby making the spiral conveying and mixing bracket 20 The feed base material and the fine materials are mixed while being transported, and there is no need for the staff to mix the feed base material and the fine materials in advance, so that the device does not need to prepare the materials for a long time when in use, and at the same time ensures that the mixed feed is continuously discharged from the inside of the device, so as to avoid a large amount of feed base material and fine materials being mixed at the same time, so that the mixed feed products are discharged from the device at the same time, and the feed mixing device is prevented from not working effectively during the material preparation stage and the discharge stage. The installation of the transmission cylinder 23, the flexible spring 24 and the vibration knocking ball 25 can make the one-way bearing of the hollow transmission shaft 19 locked when the instantaneous clockwise rotates, so that the transmission cylinder 23, the flexible spring 24 and the vibration knocking ball 25 rotate with the hollow transmission shaft 19, so that the flexible spring 24 The upper end of the vibration transmission bracket 15 is continuously knocked to make the vibration transmission bracket 15 vibrate, and the vibration is transmitted to the four material filling cylinders 2, so that the feed base material and fine materials inside the material filling cylinder 2 are smoothly discharged into the feed mixing cylinder 1 under the action of vibration, thereby preventing the feed base material and fine materials from being stuck inside the material filling cylinder 2. It should be noted that the process of air participating in the mixing is in the "traditional feed matrix and fine material mixing mode at the same time". At this time, the feed is at the upper end inside the device, and the air is blown out from the isolation net to make the air flow to the upper end inside the device. Under the action of the fan, the air circulates inside the device. At this time, when the airflow passes through the feed matrix, it can be concluded from the public knowledge that there is not no gap between the feed matrix and the feed matrix.And the matrix of fine materials will gradually penetrate to the lower end of the device as it is stirred, resulting in the deposition of fine materials, and the upward flow of air can move the fine materials upward, thereby preventing the deposition of fine materials and allowing the fine materials to fully move inside the device. At the same time, the above description has the outer surface of the spiral conveying and mixing bracket 20 to be relatively smooth, and the feed will slide on the spiral conveying and mixing bracket 20. The gas can lift up the fine materials (such as some fine materials, medicinal powder) in a small space, so that the fine materials can move under the action of the airflow, thereby increasing the degree of confusion of the materials inside the device. The gas only plays a role in assisting the mixing, so the above description "mixing under the dual action of gas and machinery" is described. At this time, it is the "traditional feed base and fine material simultaneous mixing mode" of the device, that is, only in this mode does the gas assist in mixing, and its purpose is to increase the degree of chaos of the fine material inside the device. Compared with the traditional coarse and fine materials added into the device at the same time and simply stirred and mixed, this device lifts the fine material to increase the degree of chaos of the fine material, which is conducive to the mixing of the feed base and the fine material, prevents the fine materials from piling up, and improves the mixing efficiency of the feed base and the fine material.

The air blowing fan (10) blows air into the air blowing bracket (9) via the connecting pipe (17), and the air blowing bracket (9) rotates outside the hollow transmission shaft (19) so that air passes through the air blowing bracket (9) and enters the inside of the hollow transmission shaft (19), and then the air passes through the isolation net (22) outside the hollow transmission shaft (19) and is blown onto the feed matrix and the upper end of the fine materials, so that the fine materials are blown by the air flow. The feed mixing cylinder (1) is moved downwardly so that the fine materials are fully in contact with the feed matrix. At the same time, when air is blown into the inside of the feed mixing cylinder (1), the air blows up a small amount of feed products remaining in the feed mixing cylinder (1), so that the feed can be discharged from the feed mixing cylinder (1) more smoothly. A return pipe (16) is fixedly installed on one side of the upper end of the feed mixing cylinder (1). The return pipe (16) is fixedly connected to the air inlet end of the air blowing fan (10). An air inlet and outlet pipe (27) is fixedly installed on the upper end of the return pipe (16). A first solenoid valve (28) is fixedly installed on one end of the air inlet and outlet pipe (27). A second solenoid valve (29) is fixedly installed on the upper end of the return pipe (16). The air inlet and outlet pipe (27) cooperates with the switch of the second solenoid valve (29) to make the air discharged from the feed mixing cylinder (1) carrying a small amount of fine materials return to the inside of the feed mixing cylinder (1), thereby preventing these fine materials from being discharged to the outside and causing the loss of fine materials.
