Description

Technical Field

[0001] This utility model relates to the field of potato grading machine technology, and more specifically, to an anti-clogging device for a potato grading machine. Background Technology

[0002] Potato grading machines are small to medium-sized grading and sorting machines. The particle size can be adjusted according to user requirements to grade potatoes and onions into different grades. Dumbbell rubber rollers or mirror-finish rotating rollers can be selected based on different potato shapes. They employ small drop and gentle conveying technology to achieve damage-free operation. However, some problems still exist in actual use. For example, some existing potato grading machines use rollers with different spacing to classify and collect potatoes by volume. However, this mechanism, relying on a single screening process, easily leads to upper-layer potatoes covering lower layers when processing large quantities of potatoes, affecting screening accuracy. Consequently, the size difference of the graded products is significant, reducing the overall quality and uniformity of the grading. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, this utility model provides an anti-clogging device for a potato grading machine, so as to solve the problem that in some existing grading machines, when screening potatoes, some potato material tends to cover the upper layer, resulting in poor screening effect.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an anti-clogging device for a potato grading machine, comprising...

[0005] A base, wherein a tipping bucket is fixedly installed on the top of the side end of the base along its length, and a lifting conveyor is provided in the middle of the tipping bucket;

[0006] A support frame is fixedly installed at the bottom and the top of the base. Several grading rollers are rotatably installed at the middle of the top of the support frame, and a reversible feeder is provided at the middle of the bottom of the support frame.

[0007] A circulating backflow assembly includes a collection box, a ramp, a conveying cylinder, and a discharge guide plate. The side of the collection box is fitted against the side wall of the base in the width direction. The bottom of the ramp is fixedly installed against the inner wall of the bottom of the collection box. The outer surface of the bottom of the conveying cylinder is fixedly installed against the side wall of the side end of the collection box. A motor is fixedly installed on the top of the conveying cylinder. A rotating auger is provided inside the conveying cylinder. The top of the rotating auger is fixedly connected to the output end of the motor. The bottom of the rotating auger is rotatably installed against the inner surface of the middle part of the bottom of the conveying cylinder. The side end of the discharge guide plate is fixedly installed against the outer surface of the top of the conveying cylinder.

[0008] It also includes a baffle curtain, the bottom of which is fixedly installed on the top of the bracket near the end of the tipping bucket.

[0009] It also includes an anti-clogging and cleaning component, which is located on the top of the bracket.

[0010] The anti-clogging and cleaning assembly includes an electric push rod one, a horizontal plate, a scraper sleeve, a vertical plate, and an electric push rod two. The end of the electric push rod one is fixedly installed on the side of the end of the horizontal plate. The outer surface of the end of the horizontal plate is slidably installed on the inner surface of the side of the support. The side of the scraper sleeve is fixedly installed on the surface of the horizontal plate. The inner surfaces of the horizontal plate and the scraper sleeve are slidably sleeved on the outer surface of the grading roller. The bottom end of the vertical plate is fixedly installed on the top of the end of the horizontal plate away from the electric push rod one. The side end of the electric push rod two is fixedly installed on the side of the top of the vertical plate. The middle part of the vertical plate is movably sleeved on the outside of the baffle curtain.

[0011] The horizontal plate, scraper sleeve, and vertical plate are each symmetrically arranged in twos, and are interconnected at both ends by the electric push rod one and the electric push rod two.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In the above scheme, by setting up grading rollers and a circulating reversing component, after the material is transported into the collection box by the reversible feeder, the material will roll down the inclined plate inside the collection box and accumulate to the bottom of the conveying cylinder. At this time, the motor is started, and the rotating auger connected to the motor output end rotates along the inner surface of the conveying cylinder, so that the potato material at the bottom of the conveying cylinder is lifted and transported upward along the surface of the rotating auger until it reaches the top. Then, it is put into the lifting conveyor near the support by the discharge guide plate, and then undergoes secondary or multiple grading processes by the grading rollers. This avoids the phenomenon of large product size differences after only one grading, improves the screening accuracy, and improves the overall quality and uniformity of grading.

[0014] In the above solution, by setting up an anti-clogging and cleaning component, the operator can control the retraction of electric push rod one and electric push rod two, which will drive the two horizontal plates connected at both ends to move the scraper sleeves installed on them closer to each other along the outer surface of the grading roller. During the movement, the dirt adhering to the surface of the grading roller is scraped off towards the center. After the impurities fall down onto the reversible feeder, the reversible feeder can be started to discharge the debris. This prevents the adhering dirt from affecting the actual diameter of the grading roller, thus affecting the actual grading accuracy. Furthermore, the removal of dirt also helps to reduce the surface friction of the grading roller and reduce the phenomenon of material blockage. Attached Figure Description

[0020] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0021] As attached Figure 1 To be continued Figure 3 An embodiment of this utility model provides an anti-clogging device for a potato grading machine, including...

[0022] A base 1 is provided, and a tipping bucket 2 is fixedly installed on the top of the side end of the base 1 along its length. A lifting conveyor 3 is provided in the middle of the tipping bucket 2.

[0023] The support 4 is fixedly installed at the bottom and the top of the base 1. Several grading rollers 5 are rotatably installed at the middle of the top of the support 4, and a reversible feeder 7 is provided at the middle of the bottom of the support 4.

[0024] By setting up a reversible feeder 7, after the potato material is poured into the inside of the tipping bucket 2, it is tilted upward by the lifting conveyor 3 and transported to several grading rollers 5 inside the support 4 for grading. The graded material falls downward onto the reversible feeder 7. Since the reversible feeder 7 can transport in both directions, the operator can control the reversible feeder 7 to choose to transport the graded potato material to the left circulation backflow component 8 for secondary grading, or to choose to discharge the potato material to the right, thus improving the practicality of the device.

[0025] The circulating backflow assembly 8 includes a collection box 80, a ramp plate 81, a conveying cylinder 82, and a discharge guide plate 85. The side of the collection box 80 is attached to the side wall of the base 1 in the width direction. The bottom of the ramp plate 81 is fixedly installed to the inner wall of the bottom of the collection box 80. The outer surface of the bottom of the conveying cylinder 82 is fixedly installed to the side wall of the side end of the collection box 80. A motor 83 is fixedly installed on the top of the conveying cylinder 82. A rotating auger 84 is provided inside the conveying cylinder 82. The top of the rotating auger 84 is fixedly connected to the output end of the motor 83. The bottom end of the rotating auger 84 is rotatably installed to the inner surface of the middle part of the bottom of the conveying cylinder 82. The side end of the discharge guide plate 85 is fixedly installed to the outer surface of the top of the conveying cylinder 82.

[0026] It also includes a baffle curtain 6, the bottom of which is fixedly installed on the top of the bracket 4 near the end of the tipping bucket 2;

[0027] By setting up a baffle curtain 6, which is located near the feeding position of the grading roller 5, the stacked potato material can be gently blocked, so that the upper layer of material is swept and rolled aside without damaging the surface of the material.

[0028] It also includes an anti-clogging and cleaning component 9, which is located on the top of the bracket 4.

[0029] The anti-clogging cleaning component 9 includes an electric push rod 90, a horizontal plate 91, a scraper sleeve 92, a vertical plate 93, and an electric push rod 94. The end of the electric push rod 90 is fixedly installed on the side of the end of the horizontal plate 91. The outer surface of the end of the horizontal plate 91 is slidably installed on the inner surface of the side of the bracket 4. The side of the scraper sleeve 92 is fixedly installed on the surface of the horizontal plate 91. The inner surfaces of both the horizontal plate 91 and the scraper sleeve 92 are slidably sleeved on the outer surface of the grading roller 5. The bottom end of the vertical plate 93 is fixedly installed on the top of the end of the horizontal plate 91 away from the electric push rod 90. The side end of the electric push rod 94 is fixedly installed on the side of the top of the vertical plate 93. The middle part of the vertical plate 93 is movably sleeved on the outside of the baffle curtain 6.

[0030] Among them, there are two horizontal plates 91, two scraper sleeves 92, and two vertical plates 93, which are connected to each other through electric push rod 1 90 and electric push rod 2 94.

[0031] The working process of this utility model is as follows:

[0032] After the material is transported into the collection box 80 by the reversible feeder 7, the material will roll down along the ramp plate 81 inside the collection box 80 and accumulate at the bottom of the conveying cylinder 82. At this time, the motor 83 is started, and the rotating auger 84 connected to the output end of the motor 83 rotates along the inner surface of the conveying cylinder 82, so that the potato material at the bottom of the conveying cylinder 82 is lifted and transported upward along the surface of the rotating auger 84 until it reaches the top. Then, it is put into the lifting conveyor 3 near the support 4 through the discharge guide plate 85, and then undergoes secondary or multiple grading processes through the grading roller 5. This avoids the phenomenon of large product size differences after only one grading, improves the screening accuracy, and improves the overall quality and uniformity of grading.

[0033] After a period of use, the operator can control the electric push rod 1 90 and electric push rod 2 94 to retract, which will drive the two horizontal plates 91 connected at both ends to move the scraper sleeves 92 installed on them closer to each other along the outer surface of the grading roller 5. During the movement, the dirt adhering to the surface of the grading roller 5 will be scraped off towards the center. After the impurities fall down onto the reversible feeder 7, the reversible feeder 7 can be started to discharge the debris, so as to avoid the adhering dirt affecting the actual diameter of the grading roller 5 and thus affecting the actual grading accuracy. In addition, the removal of dirt also helps to reduce the surface friction of the grading roller 5 and reduce the phenomenon of material blockage.
