Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of feed production, and particularly relates to a premixing device for feed production. BACKGROUND

[0002] In the production process of animal husbandry, the quality of feed directly affects the growth, health and final economic benefits of animals. With the continuous development of the breeding industry, the types and formulas of livestock feed are becoming increasingly complex, especially in the production of multiple livestock feed premix feed, it is necessary to accurately and uniformly mix various types of feed raw materials. This requires that the feeding equipment not only efficiently and accurately feeds the materials, but also meets the requirements of different types of feed raw materials.

[0003] Premix feed is a mixture of one or more additive raw materials (or monomers) and carriers or diluents, also known as additive premix or premix, the purpose is to facilitate the uniform dispersion of trace raw materials in a large amount of compound feed. The traditional premix feed production process mainly includes raw material storage, feeding, batching, mixing, conveying and finished product packaging.

[0004] In the traditional feed premix production process, the working mode of the mixer has obvious limitations. The operation mode is usually to add the feed to be mixed through the feeding port at one time, and then rely on the stirring blade to stir. Due to the characteristics of this operation mode, the mixer must be stopped when the feed is added, which makes it impossible to realize continuous layered feeding during stirring, and a large amount of feed can only be fed at the same time and then stirred. At the same time, this mode also has the problem of inconvenient feeding amount control, and cannot accurately control the addition ratio of various feeds. In addition, after each stirring is completed, the machine needs to be stopped, the material needs to be discharged, and the material needs to be added again, which causes a lot of idle time, low utilization rate of machinery, and seriously affects the production efficiency.

DETAILED DESCRIPTION

[0028] In order to make the purpose, characteristics and advantages of the utility model more obvious and easy to understand, the technical scheme in the utility model will be described clearly and completely in combination with the drawings in the specific embodiment. Obviously, the following described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the patent, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of the patent protection.

[0029] As Figures 1-7As shown, a premixing device for feed production includes a base 1, a plurality of hoppers 2 connected and installed on the base 1 in a symmetrical distribution, a quantitative mechanism 3, a conveying mechanism 4 and a stirring mechanism 5. The quantitative mechanism 3 includes a first auger 31 rotatably connected and installed on the inner bottom of the hopper 2. A servo motor 32 is connected and installed on the outer side of the hopper 2 to drive the rotation of the first auger 31. The first auger 31 extends to a discharge port 33 provided at the bottom of the hopper 2 away from the servo motor 32. The conveying mechanism 4 is connected and installed on the base 1 below the discharge port 33. The conveying mechanism 4 extends into a feeding port 51 of the stirring mechanism 5 on the other side. The stirring mechanism 5 includes a fixed frame 52. The fixed frame 52 is inclined, with the side away from the hopper 2 being lower than the other side. The fixed frame 52 is placed below the ground to facilitate feeding of the hopper 2. Bearing seats 53 are provided on the top of both sides of the fixed frame 52. A roller 54 is rotatably connected in the bearing seat 53. The roller 54 is driven to rotate by a power mechanism. A discharge port 511 is provided on the side of the roller 54 away from the feeding port 51. A second auger 55 is welded and installed on the inner wall of the roller 54 through punching on the outer side. The power mechanism includes a first pulley 56 installed on the outer side of the roller 54. A motor 59 is connected and installed on the fixed frame 52. A second pulley 58 is connected and installed on the output end of the motor 59. The first pulley 56 and the second pulley 58 are drivingly connected by a belt 57.

[0030] When using the device, different raw materials are first put into the corresponding hoppers 2 in bags using a grain conveyor. The servo motors 32 in each hopper 2 are started at different speeds according to the required proportion for making feed. The servo motors 32 drive the rotation of the first augers 31, which in turn convey the multiple raw materials in the predetermined proportion from the discharge ports 33 to the conveying belt and fall onto the conveying belt. The raw materials on the conveying belt are continuously conveyed into the roller 54 by the operation of the conveying mechanism 4. Under the drive of the motor 59, the belt 57 drives the pulleys to continuously rotate the roller 54, which can continuously and uniformly mix the multiple raw materials. The belt 57 can prevent overloading of the motor 59 and improve the service life of the motor 59. Since the roller 54 is inclined toward the discharge port 511, the second auger 55 welded and fixed in the roller 55 continuously conveys the raw materials to the end of the discharge port 511. This can continuously and uniformly premix the multiple raw materials in a specific proportion to obtain the required premix, facilitating the next process and greatly improving the production efficiency. Moreover, the fixed frame 52 is placed underground, which can save space above ground and facilitate feeding of the raw materials into the hoppers 2 using the machine.

[0031] The vertical long strip-shaped perspective window 21 is provided on the outer side of each hopper 2 to facilitate the operator to check the remaining amount of raw materials in the hopper 2. When reaching the set red line, the operator needs to timely supplement the raw materials. The perspective window 21 is made of smooth tempered glass to prevent the raw materials from sticking to the top and affecting observation. Moreover, the perspective window 21 is arranged on the vertical wall of the hopper 2, which greatly reduces the probability of raw materials sticking to the perspective window 21.

[0032] Wherein, the lower edge of the discharge port 33 is welded with a slanted surface-smooth stainless steel guide chute 34. It can make the raw materials from the discharge port 33 slide along the guide chute 34 to the conveyor belt, prevent the wind caused by the motor rotation from blowing the raw materials, and prevent the dust from affecting the accuracy of the proportioning.

[0033] Wherein, the conveying mechanism 4 is a transmission belt structure, and the cross section of the conveying belt is in U shape. The U-shaped conveying belt can gather the raw materials to the middle, mix different raw materials together, and prevent the wind on both sides from blowing the raw materials.

[0034] Wherein, the top of the hopper 2 is provided with a tamping mechanism 22, which includes a reduction motor 23 connected and installed on the top of the hopper 2. The output shaft of the reduction motor 23 drives and connects a rotating shaft 24, which is provided with a plurality of cranks 25 corresponding to the center position of the hopper 2. The cranks 25 are rotationally connected and installed with a tamping rod 26. The reduction motor 23 drives the rotating shaft 24 to rotate, and then drives the cranks 25 to rotate. The cranks 25 drive the tamping rod 26 to move vertically up and down in the hopper 2, which can prevent the raw materials from arching in the hopper 2, affecting the discharge, and causing the proportioning of the raw materials to be inaccurate.

[0035] Wherein, the tamping rod 26 is provided with five flow-changing blocks 27 evenly arranged along the rod, and the flow-changing blocks 27 are upper and lower symmetrical and conical bodies with large ends opposite. The flow-changing blocks 27 can affect the pressure of the raw materials on the wall of the hopper 2, improve the flowability of the materials, reduce the tamping resistance of the flow-changing blocks 27 in the raw materials, reduce the load of the reduction motor 23, and prevent the reduction motor 23 from overloading.

[0036] Wherein, the both ends of the roller 54 are provided with dustproof mechanisms 50, which include door curtain strips 501 connected and installed on both sides of the roller. A large amount of dust will be generated during the rotation and stirring of the roller. The dustproof mechanism can block most of the dust from being emitted to the outside, reducing the impact of the dust on the environment.

[0037] Wherein, the conveying mechanism 4 is a conveyor belt structure, and the lower end of the side close to the stirring mechanism 5 is provided with a brush 41 in contact with the surface of the conveying belt of the conveying mechanism 4. The brush 41 can brush off the raw materials adhered to the surface of the conveying belt, prevent the raw materials from falling off, and cause the proportioning of the premixed materials to be inaccurate and wasted.

[0038] Wherein, the inner wall of the roller 54 is also provided with circumferential array of surface-smooth stop blocks 541. In the rotation of the roller 54, the raw materials can be brought to a high enough position to be poured, making the stirring of the raw materials more uniform.

[0039] The controller uses a common PLC controller, such as Mitsubishi FX2N series. By presetting the program, when the corresponding proportioning premixed material needs to be produced, the corresponding program is selected to control the production of the device.

[0040] The second auger 55 can be double auger blades staggered and welded inside the roller 54, which can improve the stirring efficiency and stirring quality of the premix.

[0041] It should be noted that the premixing device for feed production can also be provided with a spraying device for adding corresponding liquid supplements in the premix, which is arranged inside the stirring device 5. On the one hand, it can reduce the dust of dry raw materials during stirring, and on the other hand, it can also make the liquid agent and the feed more uniform.

[0042] The above description of disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
