Detailed Description
As shown in fig. 1-3, an anti-jamming screening mechanism for fruits and vegetables comprises a double-row chain conveying mechanism 1, wherein the double-row chain conveying mechanism 1 comprises two groups of chain conveying mechanisms (a driving chain wheel, a driven chain wheel and a chain) which are arranged side by side from left to right, and the two groups of chain conveying mechanisms are coaxially connected through a transmission shaft and are positioned on the same side of a chain wheel 1.2. The transmission shaft at one end is driven to rotate by a motor. The chain 1.1 is a roller chain, a roller 2 is arranged between two groups of roller chains of the double-row chain transmission mechanism 1 at equal intervals, central shafts at two ends of the roller 2 are integrated with a pin shaft 1.1.1 of the chain 1.1, the pin shaft 1.1.1 corresponding to the roller 2 is positioned at one end of the outer side of the roller chain and extends for a distance, a sliding groove 3.3 of an adjusting component 3 freely penetrates through the pin shaft, and every two rollers 2 correspond to one group of adjusting components 3.
As shown in fig. 4-5, the adjusting component 3 comprises a left adjusting plate 3.1 and a right adjusting plate 3.2, the left adjusting plate 3.1 and the right adjusting plate 3.2 are arranged in a crossed manner at a certain included angle, the crossed and overlapped parts of the left adjusting plate 3.1 and the right adjusting plate 3.2 are fixed through bolt connection, and two sets of walking wheels 3.5 are installed at the bottom ends of the crossed parts. The left adjusting plate 3.1 and the right adjusting plate 3.2 are provided with chutes 3.3 along the length direction, and pin shafts 1.1.1 positioned at the nodes of the corresponding rollers 2 on the chains 1.1 penetrate through the chutes 3.3 and are limited by limiting plates 3.4. In this way the pin 1.1.1 can move up and down along the chute 3.3 without falling out.
As shown in fig. 4, when the adjusting assembly 3 moves upward relative to the pin 1.1.1, the two pins 1.1.1 of the chain 1.1 move downward and close together, so that the space between the two rollers 2 is reduced; when the adjusting assembly 3 moves downwards, the two pin shafts 1.1.1 of the chains 1.1 relatively move upwards and away, so that the interval between the two rollers 2 is enlarged. That is, when the two pins 1.1.1 move toward the upper traveling wheel 3.5 side of the adjusting component 3, the interval between the two rollers 2 becomes smaller, and when the two pins 1.1.1 move toward the side away from the upper traveling wheel 3.5 side of the adjusting component 3, the interval between the two rollers 2 becomes larger.
As shown in fig. 6, the double-row chain conveying mechanism 1 is mounted on a support 5, and slide rails 4 are correspondingly arranged on the left and right of the support 5. The slide rail 4 comprises a roller support rail 4.1 and an adjusting component support rail 4.2. Wherein, cylinder riding rail 4.1 horizontal setting, cylinder riding rail 4.1 surface has the line, and the wheel 2.1 that rolls is installed to the corresponding cylinder 2 left and right sides, and the wheel 2.1 surface tooth that rolls, rolls wheel 2.1 and cylinder riding rail 4.1 contact. When the chain 1.1 drives the roller 2 to move forwards, the rolling wheel 2.1 can rotate relative to the roller support rail 4.1 to drive the roller 2 to rotate, and the roller 2 rotates to accelerate screening. The adjusting component support rail 4.2 is arranged obliquely upwards along the screening conveying direction, the adjusting component support rail 4.2 is U-shaped, and the walking wheel 3.5 arranged on one side of the adjusting component 3 is arranged in the U-shaped adjusting component support rail 4.2.
As shown in fig. 7-8, a limiting ring 1.2.1 is fixed outside a chain wheel 1.2 of the double-row chain conveying mechanism 1, and the limiting ring 1.2.1 is used for limiting one end of a left adjusting plate 3.1 and one end of a right adjusting plate 3.2 of the adjusting component 3, which are far away from the intersection position. Meanwhile, an arc limiting plate 1.2.2 is arranged above the meshing part of the chain 1.1 and the chain wheel 1.2, and the arc limiting plate 1.2.2 is contacted with the chain 1.1. Through setting up spacing ring 1.2.1, arc limiting plate 1.2.2, can carry on spacingly to chain 1.1, guarantee that chain 1.1 meshes and can not take off the tooth because of the chain is not taut in sprocket 1.2 department.
The working principle and the process are as follows: the chain 1.1 in the device is in a slack state, namely the total length of the chain 1.1 is larger than the length of the chain 1.1 which is wound on the left and right chain wheels 1.2 and is in a tension state. As shown in fig. 9, during operation, when the left sprocket 1.2 rotates clockwise, the left sprocket 1.2 is limited by the limiting ring 1.2.1 and the arc limiting plate 1.2.2, the pin shaft 1.1 is located at one end of the left adjusting plate 3.1 and the right adjusting plate 3.2 far away from the intersection, when the rolling wheel 2.1 falls on the roller rail 4.1 and the walking wheel 3.5 enters the adjusting assembly rail 4.2, because the roller rail 4.1 is horizontally arranged, the adjusting assembly rail 4.2 is obliquely and upwardly arranged from left to right, and in an initial state, the distance between the roller rail 4.1 and the adjusting assembly rail 4.2 is smaller, the whole body formed by the pin shaft 1.1.1, the rolling wheel 2.1 and the roller 2 moves upward relative to the adjusting assembly 3, the distance between the adjacent pin shafts 1.1.1 is smaller, the chain 1.1 is in a loose state, and the distance between the rollers 2 is smaller. In the process of conveying the chain 1.1 from left to right, the adjusting component support rail 4.2 inclines upwards from left to right, so the adjusting component 3 is driven to gradually move upwards, the roller support rail 4.1 is horizontally arranged, the rolling wheel 2.1 horizontally moves right along the roller support rail 4.1, the rolling wheel 2.1 and the pin shaft 1.1.1 do not move longitudinally, therefore, the distance between the adjacent pin shafts 1.1 is gradually increased, the distance between the roller 2 is also gradually increased along with the rightward movement, finally when the tail end position of the adjusting component support rail 4.2 is reached (the tail end position of the adjusting component support rail 4.2 is highest), the chain 1.1 is tensioned, then the chain enters the lower part on the right side after passing through the chain wheel 1.2 again, because the adjusting component 3 is made of stainless steel, after natural sagging, the pin shaft 1.1.1 is positioned at the upper ends of the left adjusting plate 3.1 and the right adjusting plate 3.2, and the chain 1.1 is naturally straightened and conveyed forwards. Repeat above-mentioned process, at the first half section of double-row chain transport mechanism 1 promptly, the clearance grow gradually from a left side to the right of cylinder 2 conveniently sieves. If the interval of the roller 2 needs to be adjusted in the later period, only the distance and the inclination angle of the adjusting component support rail 4.2 relative to the roller support rail 4.1 need to be adjusted.
