Description

Technical Field

[0001] The utility model belongs to the technical field of automatic sample pre-processing, and in particular relates to a solid waste dumping device and a food sample pre-processing device. Background Art

[0002] Food sample pretreatment is a necessary step in food safety analysis and testing. The development of automated pretreatment equipment has greatly improved the efficiency of sample processing and reduced labor costs. During the operation of automated pretreatment equipment, the automated transfer of liquids will produce solid waste such as centrifuge tubes and pipette tips. Currently, commercialized food sample pretreatment devices do not involve automated solid waste dumping and recycling functions. After a one-time sample is processed, the solid waste needs to be removed by manual collection before the next batch of samples can be processed, which limits the efficiency of sample processing. The dumping and recycling of solid waste has not yet been automated.

[0003] In the field of environmental protection technology, relevant waste dumping devices are widely used in dumping garbage. For example, the Chinese patent application with publication number CN114873106A discloses a garbage can dumping device, including a base, a box, a dumping mechanism and a driving mechanism; the box is fixedly arranged on the base, and the driving mechanism is used to drive the dumping mechanism to move, so that the dumping mechanism drives the garbage can to complete the dumping into the box; the driving mechanism includes a fixed support fixedly arranged on the base, a hydraulic transmission rod and a transmission shaft fixedly connected to the dumping mechanism; one end of the hydraulic transmission rod is connected to the fixed support, and the other end of the hydraulic transmission rod is connected to the transmission shaft, and the telescopic action of the hydraulic transmission rod can drive the transmission shaft to rotate, and the rotation of the transmission shaft can drive the dumping mechanism to move; the authorization announcement number is CN 213893893 U's Chinese patent also discloses a trash can dumping device, the front end of the box body is provided with a dumping mechanism support frame, and the dumping mechanism is installed on the dumping mechanism support frame; the dumping mechanism includes a slide rail, a guide plate, a dumping plate and a rotating motor, two slide rails are arranged in parallel on the dumping mechanism support frame, the guide plate is installed on the slide rails, a driving shaft and a driven shaft are arranged between the guide plates, the driving shaft is connected to the rotating motor, the driven shaft slides in the guide slide groove of the guide plate, a dumping plate is arranged between the driving shaft and the driven shaft, and a trash can hook is arranged on the dumping plate. This design can realize the trash can's tilting at various angles to ensure the accurate dumping of the trash in the trash can, and the trash can can adjust its position left and right and up and down, which is suitable for the dumping of trash cans of different specifications.

[0004] However, the existing pouring device cannot be applied to food sample pretreatment equipment because the existing pouring device has a complex structural design and the driving mechanism adopts hydraulics or motors. The equipment is heavy, which will increase the complexity and production cost of the pretreatment equipment, and will affect and limit the application and promotion of the pretreatment equipment. In addition, the hydraulic drive will cause liquid leakage, resulting in the risk of food sample contamination and inaccurate test results. Utility Model Content

[0018] The number of the cylinder is one;

[0019] The length of the cavity is L, the width is B, and the depth is H;

[0020] L / B>10, L / H>2, H / B>5;

[0030] The tipping bucket is made of stainless steel or acrylic material.

[0031] The utility model provides a food sample pre-processing device comprising the above-mentioned solid waste dumping device.

[0032] Furthermore, the solid waste dumping device can move horizontally within the food sample pre-processing device.

[0033] Beneficial effects:

[0034] (1) The solid waste dumping device includes a base plate, a tipping bucket, a cylinder, a guide rail, a slider, a support, and a first connecting member. The tipping bucket is a container structure with an open top. The guide rail and the support are fixedly mounted on the base plate. One end of the cylinder is hinged to the support, and the other end is hinged to the tipping bucket. The first connecting member is hinged to the tipping bucket through a pin shaft. The slider is fixed to the bottom of the first connecting member, and the slider is slidably matched with the guide rail. When the piston rod of the cylinder is extended or shortened, the tipping bucket can be flipped around the axis of the pin shaft.

[0035] In this way, the cylinder drives the tipping bucket to flip, thereby realizing automatic dumping of solid waste. The structure is simple and compact, avoiding the inconvenience and inefficiency of manual dumping, and avoiding the problem of liquid leakage caused by hydraulic drive, which may lead to the risk of food sample contamination.

[0036] (2) The second connecting member is fixedly arranged on the outer side of an inclined wall surface of the dump bucket, and the first connecting member is hinged to the dump bucket by hinged connection with the second connecting member; and an installation space for the first connecting member and the second connecting member is formed between the inclined wall surface and the bottom plate.

[0037] In this way, an installation space for the first connecting member and the second connecting member is formed between the inclined wall and the bottom plate, making the structure of the solid waste dumping device simpler and more compact. Moreover, because the second connecting member is fixed to the outer side of an inclined wall of the bucket, the first connecting member is hinged to the bucket through the hinge with the second connecting member. Therefore, when the bucket is turned over to dump the solid waste, the solid waste can flow out along the inclined wall, making the dumping of the solid waste smoother.

[0038] (3) The cavity of the dump bucket is long, narrow and deep, with a length of L, a width of B and a depth of H; L / B>10, L / H>2, H / B>5; when the bottom of the dump bucket is horizontal, the guide rail is parallel to the length direction of the dump bucket.

[0039] In this way, the cavity of the tipping bucket is in a long, narrow and deep shape, which makes the tipping bucket more suitable for accommodating solid waste such as centrifuge tubes and pipette tips generated in the food sample pretreatment process; at the same time, the long, narrow and deep design of the tipping bucket cavity improves the capacity and dumping efficiency of the tipping bucket, while saving space; moreover, the long, narrow and deep shape of the cavity of the tipping bucket makes it possible to articulate the cylinder only on one side of the length direction of the tipping bucket without generating a large overturning moment, avoiding the need to set cylinders on both sides of the tipping bucket, thereby making the structure of the entire solid waste dumping device more compact, and the number of cylinders is reduced, which is more conducive to automatic control when the tipping bucket is flipped.

[0040] (4) It also includes a blowing device; the blowing device is arranged in the cavity of the tipping bucket and can be used for automatic cleaning of the cavity and blowing solid waste in the cavity to assist in dumping the solid waste.

[0041] In this way, the air blowing device can automatically clean the dump bucket cavity, effectively remove the residue in the cavity, reduce the need for manual cleaning, reduce the workload of operators, and improve cleaning efficiency. Moreover, by blowing the solid waste in the cavity, it helps it to be dumped out of the dump bucket more smoothly, improving the thoroughness and efficiency of dumping.

[0042] (5) The direction of the gas ejected by the blowing device is parallel to the length direction of the cavity. In this way, because the cavity is a narrow, long, narrow and deep structure, the direction of the gas ejected by the self-cleaning device is parallel to the narrow and long length direction, ensuring the high efficiency of the cleaning process and improving the cleaning quality and efficiency.

[0043] (6) The first buffer is arranged on the outer side of the inclined wall surface, and is used to buffer the collision between the inclined wall surface and the bottom plate when the bucket turns over. In this way, the arrangement of the first buffer effectively reduces the collision impact between the bucket and the bottom plate when the bucket turns over, and prolongs the service life of the device.

[0044] (7) The second buffer is arranged on the outer wall surface of the bottom of the bucket to buffer the collision between the outer wall surface of the bottom of the bucket and the bottom plate. The addition of the second buffer provides additional protection for the bottom of the bucket, further reduces the collision impact between the bucket and the bottom plate when the bucket turns over, and prolongs the service life of the device.

[0045] (8) The use of rubber pads as buffers and stainless steel or acrylic as the tipping bucket material improves the durability of the entire device and its safety in food processing environments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0051] Embodiment 1:

[0052] This embodiment provides a solid waste dumping device, which is used inside a food sample pre-processing device. Figure 1 and Figure 2 The solid waste dumping device comprises a bottom plate 1, a dump bucket 2, a cylinder 3, a guide rail 4, a slider 5, a support 6, and a first connecting member 7, wherein:

[0053] The tipping bucket 2 is a container structure with an open top; the guide rail 4 and the support 6 are both fixed on the base plate 1; one end of the cylinder 3 is hinged to the support 6, and the other end is hinged to the tipping bucket 2; the first connecting member 7 is hinged to the tipping bucket 2 through a pin 9; the slider 5 is fixed to the bottom of the first connecting member 7, and the slider 5 is slidably matched with the guide rail 4; when the piston rod of the cylinder 3 is extended or shortened, the tipping bucket 2 can be flipped around the axis of the pin 9.

[0054] In this way, the cylinder 3 drives the tipping bucket 2 to flip, thereby realizing automatic dumping of solid waste. The structure is simple and compact, avoiding the inconvenience and inefficiency of manual dumping, and avoiding the problem of liquid leakage caused by hydraulic drive, which may lead to the risk of food sample contamination.

[0055] Specifically, refer to Figure 1 and Figure 2 , and also includes a second connecting member 8, which is fixedly arranged on the outer side of an inclined wall of the dump bucket 2. In the present embodiment, when the bottom of the dump bucket 2 is in a horizontal state, the angle formed by the inclined wall and the bottom plate 1 on the outer side of the dump bucket 2 is an acute angle, and the first connecting member 7 is hinged with the second connecting member 8 through a pin 9, thereby realizing the hinge with the dump bucket 2; an installation space for the first connecting member 7 and the second connecting member 8 is formed between the inclined wall and the bottom plate 1.

[0056] In this way, an installation space for the first connecting member 7 and the second connecting member 8 is formed between the inclined wall and the bottom plate 1, making the structure of the solid waste dumping device simpler and more compact. Moreover, because the second connecting member 8 is fixed to the outer side of an inclined wall of the tipping bucket 2, the first connecting member 7 is hinged to the tipping bucket 2 through the hinge with the second connecting member 8. Therefore, when the tipping bucket 2 is turned over to dump the solid waste, the solid waste can flow out along the inclined wall, making the dumping of the solid waste smoother.

[0057] As an optimization, refer to Figure 1 and Figure 2 The cavity of the dump bucket 2 is in a long, narrow and deep shape, with a length of L, a width of B and a depth of H. In order to achieve the long, narrow and deep shape, as an example, the relationship between the length, width and depth can be: L / B>10, L / H>2, H / B>5. When the bottom of the dump bucket 2 is in a horizontal state, the guide rail 4 is parallel to the length direction of the dump bucket 2.

[0058] In this way, the cavity of the tipping bucket 2 is in a long, narrow and deep shape, which makes the tipping bucket 2 more suitable for accommodating solid waste such as centrifuge tubes and pipette tips generated in the food sample pretreatment process; at the same time, the long, narrow and deep design of the cavity of the tipping bucket 2 improves the capacity and dumping efficiency of the tipping bucket 2, while saving space; moreover, the long, narrow and deep shape of the cavity of the tipping bucket 2 makes it possible to hinge the cylinder only on one side of the length direction of the tipping bucket 2 without generating a large overturning moment, avoiding the need to set the cylinder 3 on both sides of the tipping bucket 2, thereby making the structure of the entire solid waste dumping device more compact, and the number of cylinders 3 is reduced, which is more conducive to the automatic control of the tipping bucket 2 when it is flipped.

[0059] As a further optimization, a blowing device (not shown) is also included. The blowing device is arranged in the cavity of the tipping bucket 2 and can be used for automatic cleaning of the cavity and blowing solid waste in the cavity to assist in dumping the solid waste.

[0060] In this way, the air blowing device can automatically clean the cavity of the tipping bucket 2, effectively remove the residue in the cavity, reduce the need for manual cleaning, reduce the workload of operators, and improve cleaning efficiency. Moreover, by blowing the solid waste in the cavity, it helps it to be dumped out of the tipping bucket more smoothly, thereby improving the thoroughness and efficiency of dumping.

[0061] As a further optimization, the direction of the gas ejected by the blowing device is parallel to the length direction of the cavity. In this way, because the cavity is a narrow, long, narrow and deep structure, the direction of the gas ejected by the self-cleaning device is parallel to the narrow and long length direction, ensuring the high efficiency of the cleaning process and improving the cleaning quality and efficiency.

[0062] As a further optimization, refer to Figure 1 and Figure 2 The first buffer 10 is arranged on the outer side of the inclined wall surface, and is used to buffer the collision between the inclined wall surface and the bottom plate 1 when the bucket 2 turns over. In this way, the arrangement of the first buffer 10 effectively reduces the collision impact between the bucket 2 and the bottom plate 1 when the bucket 2 turns over, and prolongs the service life of the device.

[0063] As a further optimization, refer to Figure 2 The second buffer 12 is arranged on the outer wall surface of the bottom of the bucket 2 to buffer the collision between the outer wall surface of the bottom of the bucket 2 and the bottom plate 1. The addition of the second buffer 12 provides additional protection for the bottom of the bucket 2, further reduces the collision impact between the bucket 2 and the bottom plate 1 when the bucket 2 is turned over, and prolongs the service life of the device.

[0064] In this embodiment, the dump bucket 2 is composed of Figure 1 The state in the clockwise flip to Figure 2When the slider 5 is in the middle state, it slides along the guide rail 4 toward the direction close to the support 6. When the clockwise flip angle of the tipping bucket 2 is too large, the outer side of the inclined wall may collide with the bottom plate 1, and the first buffer 10 can buffer the collision. Figure 2 The state in the counterclockwise flip to Figure 1 In the state, the slider 5 slides along the guide rail 4 in the direction away from the support 6. When the tipping bucket 2 flips counterclockwise at a large angle, the outer side of the bottom of the tipping bucket 2 may collide with the bottom plate 1, and the second buffer 12 can buffer the collision; and, referring to Figure 1 and Figure 2 A notch 11 is provided on the inclined wall surface, and the notch 11 is located at a position close to the inclined wall surface at the top open end of the dump bucket 2. Figure 2 , the solid waste in the tipping bucket 2 can flow along the inclined wall surface and finally flow out smoothly from the notch 11 on the inclined wall surface to a waste bucket (not shown) or other collecting device. In this embodiment, a rubber pad can be used as a buffer, and stainless steel or acrylic can be used as the material of the tipping bucket 2, which can improve the durability of the entire device and the safety in a food processing environment.

[0065] In addition, it should be noted that in this embodiment, the air source, air supply pipeline and valve on the air supply pipeline for supplying air to the cylinder 3 and the blowing device, as well as the automatic control device for controlling the movement of the valve, the blowing device and the cylinder 3 are not shown in the figure.
