Description

Technical Field

[0001] This utility model belongs to the field of feed production technology, and in particular relates to a roller feed pellet mill. Background Technology

[0002] Feed generally refers to the food given to animals in agriculture or animal husbandry. Powdered feed differs from pelleted feed, crushed feed, and liquid feed. Powdered feed is simple to produce and has low processing costs, but its production requires various equipment. Roller feed pellet mills are one of the key pieces of equipment that can significantly improve feed pelleting efficiency.

[0003] A search revealed that publication number CN211838104U, filed on January 20, 2020, discloses a high-efficiency multi-roller feed pellet mill, belonging to the field of pellet mill technology. It includes a main body shell with a feed inlet on its upper surface. A screening screen is installed inside the feed inlet, and first pins are installed at both ends of the screening screen. An electric push rod is engaged within the main body shell. This high-efficiency multi-roller feed pellet mill, through the inclusion of an electric push rod, first pins, a screening screen, a discharge pipe, and a receiving box, uses the screening screen to filter large particles of impurities in the feed. The electric push rod automatically tilts the screening screen, allowing the particles to be poured into the discharge pipe and discharged into the receiving box for unified collection. This effectively separates feed from impurities, facilitating processing by workers, ensuring high-quality feed processing while reducing workload.

[0004] However, it still has the following drawbacks in practical use:

[0005] The existing roller feed pellet mill cannot adjust the size of the feed inlet as needed, which leads to excessive feed accumulation inside the machine, affecting the normal crushing efficiency and effect.

[0006] 2. Existing roller feed pellet mills lack buffering measures for the crushing structure during use, affecting its service life. Therefore, we provide a roller feed pellet mill to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0031] Please see Figures 1 to 3 This utility model is a roller feed pellet mill, including a machine housing 100 and a feed hopper 101 fixed on its top. A protective shell 102 is fixed on one side wall of the feed hopper 101. A guide plate 104 is fixed on the top of the inside of the machine housing 100. An adjustment component 200 is provided inside the machine housing 100. The adjustment component 200 includes a first motor 103a installed on one side wall of the feed hopper 101 and a third rotating shaft 202 installed on the output shaft of the first motor 103a through a reducer. The other end of the third rotating shaft 202 passes through a bearing on the feed hopper 101 and is connected to a bearing on the inner wall of the feed hopper 101. A lever 203 is sleeved on the outer wall of the third rotating shaft 202. An adjustment plate 204 is provided directly behind the lever 203. A fourth rotating shaft 204a is fixed on the inner wall of the adjustment plate 204.

[0032] Specifically, the housing 100 houses a crushing assembly 103, which includes a first motor 103a mounted on the outer wall of the housing 100 and a first pulley 103b mounted on the output shaft of the first motor 103a. The outer wall of the first pulley 103b is connected to the outer wall of a second pulley 103c via a belt. A first rotating shaft 103d is fixed in the middle of the inner wall of the second pulley 103c. One end of the first rotating shaft 103d passes through bearings on both side walls of the housing 100 and is connected to a third pulley 103f. A main crushing roller 103e is sleeved in the middle of the outer wall of the first rotating shaft 103d, and the third pulley 103f... The outer wall is connected to the outer wall of the fourth pulley 103g via a belt drive. The second rotating shaft 103h is fixed in the middle of the inner wall of the fourth pulley 103g. One end of the second rotating shaft 103h passes through the bearings on both sides of the machine housing 100. The auxiliary crushing roller 103i is sleeved in the middle of the outer wall of the second rotating shaft 103h. Rotating plates 103j are installed at both ends of the outer wall of the second rotating shaft 103h. One end of the fourth rotating shaft 204a passes through the bearing on the feed hopper 101 and is fixedly connected to the connecting plate 205. The top end of the connecting plate 205 is movably connected to the telescopic end of the electric push rod 206 via a hinge. The electric push rod 206 is installed on the inner wall of the protective shell 102.

[0033] Furthermore, the guide plate 104 can guide the feed to be fed, and plays a guiding role. The paddle plate 203 is provided in multiple pieces. Under the action of the belt, the first pulley 103b, the second pulley 103c, the third pulley 103f, and the fourth pulley 103g can rotate synchronously, which plays a transmission role. It can control the speed of feed entering, avoid feed accumulation, and avoid affecting the crushing effect.

[0034] The operation process of this embodiment is as follows: When feed needs to be crushed, feed is fed into the machine casing 100 through the feed hopper 101. At this time, the second motor 201 is started, and the output shaft of the second motor 201 rotates, driving the third rotating shaft 202 to rotate. Moreover, the rotation of the third rotating shaft 202 will drive the baffle 203 on its outer wall to rotate synchronously. Since there are multiple baffles 203, feed can be circulated into the machine casing 100. When there is too much feed inside the machine casing 100, the electric push rod 206 is activated. The extension or retraction of the telescopic end of the push rod 206 will cause the top of the connecting plate 205 to move. The connecting plate 205 is fixed on the outer wall of the fourth rotating shaft 204a, and the fourth rotating shaft 204a is rotatably installed on the inner wall of the feed bin 101. Therefore, when the top of the connecting plate 205 is subjected to force, its bottom will rotate around the fourth rotating shaft 204a as the center, thereby adjusting the angle of the adjusting plate 204 to control the size of the feed inlet of the feed bin 101. This makes it easy to adjust the size of the feed inlet according to the amount of feed and avoids affecting the normal crushing efficiency of the feed. Example 2

[0035] Please see Figure 2 , Figure 4 and Figure 5 Based on Embodiment 1, the difference from the first embodiment is that a buffer assembly 300 is provided. The buffer assembly 300 includes a mounting plate 301 installed on the rear end face of the housing 100 and a guide rod 302 slidably sleeved in the sliding hole on the mounting plate 301. This solves the problem that existing roller feed pellet mills lack buffering measures for the crushing structure during use, which affects the service life of the crushing structure.

[0036] Specifically, a limiting disc 302a is fixed at one end of the guide rod 302, and the other end of the guide rod 302 is rotatably mounted on the top of the outer wall of the rotating plate 103j. A retaining ring 302b is installed at one end of the outer wall of the guide rod 302. A buffer spring 303 is sleeved on the outer wall of the guide rod 302, and the buffer spring 303 is located between the mounting plate 301 and the retaining ring 302b.

[0037] Furthermore, when the auxiliary crushing roller 103i is subjected to force, it will cause the rotating plate 103j to shake. The shaking of the rotating plate 103j will cause the guide rod 302 to move along the sliding hole on the mounting plate 301, thereby squeezing the buffer spring 303 and playing a buffering role. The retaining ring 302b is a nut, which is sleeved on the outer wall of the guide rod 302 and plays a limiting role for the buffer spring 303.

[0038] The operation process of this embodiment is as follows: After the feed is fed, the first motor 103a is started. The output shaft of the first motor 103a rotates, driving the first pulley 103b to rotate. The outer wall of the first pulley 103b is connected to the second pulley 103c via a belt. Therefore, when the first pulley 103b rotates, it will drive the second pulley 103c to rotate under the action of the belt. The rotation of the second pulley 103c will drive the first rotating shaft 103d and the third pulley 103f on its inner wall to rotate, and cause the main crushing roller 103e on its outer wall to rotate synchronously. The outer wall of the third pulley 103f is connected to the outer wall of the fourth pulley 103g via a belt. The fourth pulley 103g rotates, which drives the second shaft 103h to rotate, and the auxiliary crushing roller 103i on its outer wall rotates synchronously. Under the action of the main crushing roller 103e and the auxiliary crushing roller 103i, the feed can be crushed. During the crushing process, the auxiliary crushing roller 103i will be subjected to force and shake. The shaking of the auxiliary crushing roller 103i will drive the second shaft 103h to shake, which will push the guide rod 302 to slide. With the cooperation of the mounting plate 301 and the retaining ring 302b, the buffer spring 303 is squeezed. Under the elastic action of the buffer spring 303, it can play a buffering role, protect the crushing structure, and increase the service life.
