Description

Technical Field

[0001] This utility model relates to the field of peanut processing technology, and in particular to a peanut seed peeling device. Background Technology

[0002] Peanut seeds require peeling equipment during production. One existing peanut seed peeling device, disclosed in CN222099049U, uses a single motor to drive a worm gear and bevel gear transmission system, simultaneously rotating a feeding groove roller and causing a stirring mechanism to oscillate back and forth. The rotating feeding groove roller quantitatively and evenly receives and transports peanut seeds to the peeling machine through its surface grooves. Simultaneously, an eccentric transmission wheel at the end of the transmission system is converted into an oscillating motion via a movable frame, driving the stirring frame in the feed hopper to continuously disperse the seeds and break up any "arch bridge" blockages. However, this equipment has a long transmission path, a loose structure, and occupies a large space. The continuous rotation of the feeding groove roller and the continuous feeding process result in a continuous load on the downstream peeling machine. Under certain circumstances, this can lead to overload of the peeling machine, affecting the peeling effect and increasing the risk of seed breakage. Utility Model Content

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-4 As shown, a peanut seed peeling device includes a peanut seed peeling machine 1. The feed inlet at the top of the peanut seed peeling machine 1 is connected to a feed hopper 2. The feed hopper 2 is equipped with a stirring mechanism to prevent peanut seeds from bridging. A transmission mechanism is provided on one side of the feed hopper 2, and a feeding mechanism for intermittent feeding is provided at the bottom of the feed hopper 2.

[0024] In this embodiment, the stirring mechanism includes a stirring frame 31 rotatably connected inside the feed hopper 2, with multiple U-shaped stirring arms on the stirring frame 31. One end of the stirring frame 31 is fixedly connected to a slide rod 32, and a sliding bushing 33 is fitted on the slide rod 32. The sliding bushing 33 is rotatably connected to a swing arm 45 via a horizontal pin, allowing the slide rod 32 to slide within the sliding bushing 33 and swing with the swing arm 45. The reciprocating swing of the swing arm 45 drives the sliding bushing 33, which is rotatably connected to it, to perform a reciprocating motion along an arc trajectory. The arc motion of the sliding bushing 33 drives the slide rod 32, causing it to slide relative to the bushing. At the same time, the slide rod 32 as a whole swings around the connection point with the stirring frame 31, thereby driving the stirring frame 31 to swing back and forth. The swing of the stirring frame 31 can effectively break the "arch bridge" structure formed between the peanut seeds, loosen the material, and ensure that the peanut seeds can flow continuously and evenly to the feeding mechanism below, which is the key to ensuring the continuous and stable operation of the equipment.

[0025] In this embodiment: the transmission mechanism includes a geared motor 41 fixed to one side of the feed hopper 2 via a motor support. A crank 42 is fixedly connected to the output shaft of the geared motor 41. A first connecting rod 43 is hinged to the crank 42. The end of the first connecting rod 43 away from the crank 42 is rotatably connected to a second connecting rod 44 and a third connecting rod 47 via a pin. The second connecting rod 44 is hinged to the upper end of the swing arm 45. Two limiting rods 46 are fixedly connected to both sides of the second connecting rod 44 on the swing arm 45. A limiting block 48 is fixedly connected to the swing arm 45. The geared motor 41 outputs continuous rotational power, driving the crank 42 fixed to its output shaft to rotate synchronously. The crank 42 transmits the circular motion to the linkage mechanism composed of the second connecting rod 44 and the third connecting rod 47 through the first connecting rod 43. The linkage mechanism converts the rotational motion into a specific reciprocating oscillation and ultimately drives the swing arm 45 to swing. To ensure smooth and reliable operation, limiting rods 46 are provided on the swing arm 45 to constrain the swing amplitude of the connecting rod.

[0026] In this embodiment, the feeding mechanism includes a pawl 51 hinged to the third link 47, limit blocks 48 on both sides of the pawl 51, and a ratchet 52 rotatably connected to the lower end of the swing arm 45. A horizontally arranged feeding roller 53 is fixedly connected to one side of the ratchet 52. The surface of the feeding roller 53 is provided with a peanut seed receiving groove and is rotatably connected to the bottom of the feed hopper 2. Under the constraint of the limit blocks 48, the swing of the third link 47 drives the pawl 51 to slide up and down along the direction of the swing arm 45 while simultaneously performing a compound motion with the swing of the swing arm 45. When the pawl 51 slides to engage with the ratchet 52, it pushes the ratchet 52 to rotate at a fixed angle as the swing arm 45 swings. When the swing arm 45 swings in the opposite direction, the pawl 51 rises along the groove of the limit block 48 and disengages, while the ratchet 52 remains stationary, thereby realizing the intermittent rotation of the ratchet 52, which ultimately drives the feeding roller 53 to complete the intermittent feeding operation.

[0027] The working principle and usage of this utility model are as follows: The device is powered by a reduction motor 41 fixed on a motor support. Its output shaft drives the crank 42 to rotate. The rotation of the crank 42 first pulls the first connecting rod 43, and then, through a common pin joint, drives the second connecting rod 44 and the third connecting rod 47 to move together. Finally, the second connecting rod 44 directly drives the swing arm 45 to reciprocate. This reciprocating motion drives the sliding bushing 33, which is rotatably connected to it, to reciprocate along an arc trajectory. The arc motion of the sliding bushing 33 drives the sliding rod 32 to slide relative to it within the bushing. At the same time, the sliding rod 32 as a whole swings around its connection point with the agitator 31, thereby driving the agitator 31 to swing back and forth. The swing of the stirring frame 31 can effectively break the "arch bridge" structure formed between peanut seeds, loosen the material, and ensure that the peanut seeds can flow continuously and evenly to the feeding mechanism below, which is the key to ensuring the continuous and stable operation of the equipment. On the other hand, the swing of the swing arm 45 drives the pawl 51 to work: the pawl 51, which is hinged to the third connecting rod 47, is constrained by the sliding groove of the limiting block 48. It swings with the swing arm 45 and periodically slides down to engage with the ratchet 52, pushing it to rotate at a fixed angle. When the swing arm 45 swings in the opposite direction, it slides up and disengages, thereby realizing the intermittent rotation of the ratchet 52. Finally, it drives the feeding roller 53, which has peanut seed receiving grooves on its surface, to intermittently and quantitatively transfer the peanut seeds to the peanut seed peeling machine 1 below.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
