Description

Technical Field

[0001] This utility model relates to the field of feed pelleting and cooling technology, and in particular to a feed pelleting and cooling device. Background Technology

[0002] Feed pelleting is a very important technology in modern animal husbandry production. It has the advantages of improving feed utilization, reducing feed waste, improving feed quality, and facilitating storage and use. However, pelleted feed generates heat during pelleting, and overheated pelleted feed is inconvenient to store. Therefore, a feed pelleting cooling device is needed to cool down the pelleted feed.

[0003] Existing cooling devices typically involve feeding pellets into a cooling box, where a cold air blower cools the inside of the box before discharging the pellets from the outlet. However, the internal space of the cooling box is fixed, and the feed pellets remain inside for too short a time, resulting in poor cooling efficiency. Furthermore, the feed pellets are not screened during discharge, leading to the release of small, substandard pellets. Therefore, we propose a feed pelleting cooling device to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the short residence time of feed pellets in the box leading to poor cooling effect and the lack of screening of feed pellets during feeding, and to propose a feed pelleting cooling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A feed pelleting cooling device, comprising:

[0007] The feed cooling box has through holes at the top and bottom for feeding and discharging, and air inlets and outlets on both sides.

[0008] The feed hopper is located on the top through-hole of the feed cooling box and is used to allow pelleted feed to enter the feed cooling box.

[0009] The base is fixedly installed at the bottom of the feed cooling box;

[0010] Four support bases are evenly spaced at the bottom of the base to support the feed cooling box;

[0011] The device also includes:

[0012] A cold air blower is installed on the air inlet on one side of the feed cooling box to blow air and cool the feed cooling box.

[0013] A protective box is located on the other side of the feed cooling box to protect the components on the feed cooling box.

[0014] The conveying assembly is located inside the feed cooling box and is used to convey pelleted feed.

[0015] The vibration assembly is located on top of the base and inside the feed cooling box. It is used to discharge the cooled pelleted feed.

[0016] In one possible design, the conveying assembly includes two first conveyor belts and two second conveyor belts, which are arranged alternately and vertically within the feed cooling box. The two first conveyor belts and the two second conveyor belts are respectively connected to a first drive assembly and a second drive assembly.

[0017] In one possible design, the first drive assembly includes a first motor, which is fixedly mounted inside the protective box. A first drive shaft and a first driven shaft are rotatably connected to two first conveyor belts, and both the first drive shaft and the first driven shaft rotate inside the feed cooling box. One end of each of the two first drive shafts penetrates the inner wall of the feed cooling box and extends to the outer side. A first synchronous pulley is fitted on each of the two first drive shafts, and the two first synchronous pulleys are connected to the same first synchronous belt. A first driven gear is fixedly fitted on the lower first drive shaft, and a first drive gear is fixedly fitted on the output end of the first motor. The first drive gear and the first driven gear mesh with each other.

[0018] In one possible design, the second drive assembly includes a second motor fixedly mounted inside the protective box. A second drive shaft and a second driven shaft are rotatably connected to each of the two second conveyor belts. Both the second drive shaft and the second driven shaft are rotatably connected inside the feed cooling box. One end of each of the two second drive shafts penetrates the inner wall of the feed cooling box and extends to the outer side. A second synchronous pulley is fitted onto each of the two second drive shafts. The two second synchronous pulleys are connected to the same second synchronous belt. A second driven gear is fixedly fitted onto the lower second drive shaft. A second drive gear is fixedly fitted onto the output end of the second motor. The second drive gear and the second driven gear mesh with each other.

[0019] In one possible design, the vibration assembly includes a screen plate located inside a feed cooling box. Four fixing blocks are fixedly connected at equal intervals to the top of the base, and each of the four fixing blocks is fixedly connected to a compression spring. The top of the compression spring is fixedly connected to the bottom of the screen plate. Two connecting blocks are fixedly connected to the bottom of the screen plate, and the two connecting blocks are rotatably connected to the same rotating rod. Two rotating weights are fixedly mounted on the rotating rod. A vibration motor is fixedly connected to one side of one of the connecting blocks, and the output end of the vibration motor is fixedly connected to the rotating rod.

[0020] In one possible design, the air outlet of the feed cooling box is fixedly connected to a cyclone dust collector for dust removal from the blown hot air.

[0021] In this application, the first motor and the second motor are started first. The rotation of the first motor drives the first synchronous belt to rotate, so that the two first conveyor belts connected to the first synchronous belt can start and wait to transport feed. At the same time, the start of the second motor drives the second synchronous belt to rotate, so that the two second synchronous belts can also start and wait to transport feed. Then, the cold air fan located on one side is started. The cold air blown out of the cold air fan enters the interior of the feed cooling box through the air inlet of the feed cooling box, waiting to cool the feed.

[0022] Next, the pelleted feed enters the feed cooling box from the feed hopper. It first falls onto the topmost first conveyor belt, then is conveyed onto the second synchronous belt, and then onto the bottom first conveyor belt. This cycle repeats twice, increasing the time the feed spends in the cooling box and exposed to cold air for a longer period, thus improving the cooling effect. Simultaneously, the vibrating motor at the bottom starts, driving the rotating rod to rotate. The two rotating weights on the rotating rod also rotate. The upward rotation of the weights causes the screen plate to produce planar rotary vibration, while the downward rotation causes the screen plate to produce conical rotary vibration. The elasticity of the screen plate and the base, combined with the vibration generated by the rotating weights, creates a compound rotary vibration of the screen plate, causing the feed to move on the screen plate. This allows the cooled feed to be removed from the feed cooling box, while simultaneously screening the feed and filtering out small, unqualified feed particles. A cyclone dust collector is installed at the air outlet of the feed cooling box to reduce dust generated during the cooling process, effectively reducing dust in the blown hot air.

[0023] Beneficial effects:

[0024] In this utility model, the feed pelleting cooling device uses a staggered arrangement structure of the conveying components to ensure uniform conveying of the pelleted feed. At the same time, the time the feed pellets spend in the cooling box is increased, and the time they are exposed to cold air is longer, thus improving the cooling effect.

[0025] In this utility model, the feed pelleting and cooling device realizes automatic feeding of cooled feed through a vibration component, which simplifies the operation process. At the same time, it can screen the pelleted feed and filter out small and unqualified feed pellets.

[0026] In this utility model, the feed pelleting cooling device, by using a cold air fan and a cyclone dust collector installed at the air inlet and air outlet of the feed cooling box, not only improves the cooling effect but also effectively reduces the dust in the blown hot air.

[0027] In this invention, by setting up staggered conveying components, the time that the pelleted feed spends in the feed cooling box is increased, and the time it is exposed to cold air is longer, thereby improving the cooling effect. The vibration component enables automatic feeding of the cooled feed and simultaneously screens out small and unqualified feed pellets. By setting up a cold air fan and a cyclone dust collector at the air inlet and outlet of the feed cooling box, not only is the cooling effect improved, but the dust in the blown hot air is also effectively reduced.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Example 1

[0035] Reference Figure 1-4 A cooling device includes a feed cooling box 1, four support bases 2, a feed hopper 3, a base 4, a cold air blower 6, a protective box 7, a conveying assembly, and a vibration assembly.

[0036] The feed cooling box 1 has a rectangular structure with through holes at the top and bottom. The top through hole is used to connect to the feed hopper 3 so that the pellet feed can enter the feed cooling box 1 smoothly. The bottom through hole serves as the discharge port, from which the cooled feed is discharged. The feed cooling box 1 has an air inlet and an air outlet on both sides, with the air inlet located at the air outlet of the air cooler 6.

[0037] Four support bases 2 are evenly spaced at the bottom of the base 4 to provide stable support for the feed cooling box 1. The base 4 is fixedly connected to the bottom of the feed cooling box 1 to enhance the overall structural stability.

[0038] A cooler 6 is installed on the air inlet on one side of the feed cooling box 1 to cool the inside of the feed cooling box 1 by blowing air. A protective box 7 is installed on the other side of the feed cooling box 1 to house and protect the drive components such as the motor, preventing them from being interfered with or damaged by the external environment.

[0039] The conveying assembly includes two first conveyor belts 8 and two second conveyor belts 11, which are arranged alternately and vertically inside the feed cooling box 1 to form a continuous conveying path, thereby increasing the time that the pelleted feed stays in the feed cooling box 1 and improving the cooling effect. The first conveyor belts 8 and the second conveyor belts 11 are driven by the first drive assembly and the second drive assembly, respectively.

[0040] The first drive assembly consists of a first motor 10, a first drive shaft 801, a first driven shaft 802, a first synchronous pulley, a first synchronous belt 9, and a gear transmission mechanism. The first motor 10 is fixed inside the protective box 7 and drives the two first drive shafts 801 to rotate through the gear transmission mechanism, thereby driving the first conveyor belt 8 to transport materials.

[0041] The structure of the second drive assembly is similar to that of the first drive assembly, including a second motor 13, a second drive shaft 111, a second driven shaft 112, a second synchronous pulley and a second synchronous belt 12, and a corresponding gear transmission mechanism. The second motor 13 is also fixed inside the protective box 7 and drives the two second drive shafts 111 to rotate through the gear transmission mechanism, thereby driving the second conveyor belt 11 to transport materials.

[0042] The vibration assembly is located on top of the base 4, inside the feed cooling box 1. The assembly mainly consists of a screen plate 15, a compression spring 19, a connecting block 16, a rotating rod 17, a rotating weight 18, and a vibration motor 14. The screen plate 15 is used to receive the cooled feed and achieve uniform feed distribution through vibration. The compression spring 19 connects the screen plate 15 and the base 4, and plays a role in buffering and supporting. The vibration motor 14 drives the rotating rod 17 and the rotating weight 18 to rotate, thereby generating a vibration effect and promoting the flow and distribution of feed on the screen plate 15.

[0043] This application can be used in the field of feed pelleting and cooling technology, or in other fields applicable to this application.

[0046] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 10, the second motor 13 and the vibration motor 14 are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
