Description

Technical Field

[0001] This utility model relates to the field of weighing bucket sampling technology, and in particular to a weighing bucket sampling anti-blocking sampling port structure. Background Technology

[0002] The hopper sampling anti-clogging sampling port structure is mainly used in industrial weighing equipment. Its double-layer anti-clogging design achieves efficient and stable material sampling. Its core structure includes: a sealed design located above the sampling port to prevent dust from directly entering the sampling area, avoiding initial clogging; and a structure located below the sampling port that adjusts the material's falling trajectory to prevent the accumulation of large particles or sticky materials. This structure works in conjunction with the first anti-clogging structure to form a dynamic anti-clogging mechanism. Some models are equipped with a backflushing function, using system pressure to periodically flush the sampling port, reducing the risk of long-term clogging. This structure is widely used in industrial weighing scenarios, especially when handling materials containing ash or sticky substances, effectively extending equipment maintenance cycles and ensuring sampling accuracy.

[0003] An existing anti-blocking sampling port structure for weighing buckets poses a danger when using shovels to sample from a six-meter platform weighing bucket, which can easily lead to safety and equipment accidents. When workers open the side door of the weighing bucket to collect the sample with shovels, the impact force of the material during the vibrating process of the screen into the weighing bucket is large, which can easily cause the shovel to fall into the weighing bucket and injure the workers. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a sampling port structure with anti-clogging function for weighing bucket sampling.

[0005] This utility model is achieved by the following technical solution: a sampling port structure with anti-blocking sampling hopper, including a sampling hopper, a push handle fixedly connected to the surface of the sampling hopper, a reinforcing crossbar fixedly connected to the surface of the sampling hopper, and a moving wheel fixedly connected to the surface of the reinforcing crossbar. Both ends of the sampling vehicle are fixedly connected to support frames. Limiting uprights are inserted inside the support frames. Limiting springs are slidably connected inside the limiting uprights. Limiting plates are fixedly connected to the surface of the limiting springs. Lifting springs are fixedly connected to the top of the inner wall of the limiting uprights. Lifting crossbars are fixedly connected to the bottom of the lifting springs. Adjusting screws are threadedly connected to the top of the lifting crossbars. Connecting crossbars are threadedly connected to the surface of the adjusting screws.

[0006] Through the above technical solution, the lifting spring and adjusting screw, which are slidably connected inside the limiting rod, work together to ensure the rigid positioning after the screw is adjusted, and to absorb dynamic errors through the spring, thereby improving the accuracy of repeated sampling.

[0007] As a further improvement to the above scheme, the connecting horizontal plate is fixedly connected to the surface of the limiting upright. The number of limiting uprights is set to two, and the two limiting uprights are symmetrically distributed on the left and right sides with the sampling truck bucket as the center.

[0008] As a further improvement to the above scheme, the moving wheels are located at the bottom of the sampling hopper, the surface of the limiting upright is in contact with the left and right end surfaces of the sampling hopper, and the bottom of the limiting top plate is in contact with the top surface of the support frame.

[0009] The above technical solutions promote the ergonomic design of the handrails, and the movable wheels enable a single person to easily push the equipment to the sampling point. The plug-in structure of the support frame and the limiting pole supports quick disassembly, making it easy to clean or replace worn parts.

[0010] As a further improvement to the above scheme, the number of lifting springs and lifting crossbars is set to two, and the two lifting springs and lifting crossbars are symmetrically distributed on the left and right sides with the sampling truck bed as the center.

[0011] With the above technical solution, the adjustable screw is symmetrically distributed around the sampling hopper. By rotating the screw, the distance between the connecting cross plate and the limiting upright can be precisely adjusted, achieving millimeter-level control of the sampling port gap, and adapting to the sampling needs of materials with different particle sizes.

[0012] As a further improvement to the above scheme, the number of limiting springs and limiting support plates is set to four, with each pair forming a group. The four limiting springs and limiting support plates are symmetrically distributed front and back around the limiting upright.

[0013] As a further improvement to the above scheme, the adjusting screw is located at the bottom of the limiting top plate, and the number of adjusting screws is set to two, which are symmetrically distributed on the left and right sides with the sampling truck bucket as the center.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes the rotating adjusting screw within the connecting horizontal plate to drive the lifting horizontal bar, which, in conjunction with the lifting spring, adjusts the height of the limiting upright. After adjustment, the lifting spring, along with the compression limiting spring and limiting support plate, adjusts the front-to-back position within the limiting upright, increasing the stability of the sampling hopper after it has moved to the appropriate position. The long handle allows for easy material receiving, as the material receiving trough only needs to enter the weighing hopper's side door, effectively preventing injuries and the weighing hopper from falling.

[0015] This utility model forms a rigid frame by connecting a support frame and a limiting upright, which restricts the lateral displacement of the sampling truck bed. The bottom of the limiting top plate contacts the top of the support frame, providing vertical limiting and ensuring that the truck bed maintains a stable posture under vibration or impact. The reinforcing crossbar spans the surface of the sampling truck bed and forms a triangular stable structure with the moving wheels to prevent tipping. The moving wheels are located at the bottom of the truck bed, lowering the center of gravity and improving the flexibility of movement. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0019] Please combine Figure 1-4 This embodiment of a sampling anti-blocking sampling port structure includes a sampling hopper 1, a push handle 2 fixedly connected to the surface of the sampling hopper 1, a reinforcing crossbar 3 fixedly connected to the surface of the sampling hopper 1, and a moving wheel 4 fixedly connected to the surface of the reinforcing crossbar 3. Both ends of the sampling hopper 1 are fixedly connected to support frames 5. Limiting rods 7 are inserted inside the support frames 5. Limiting springs 8 are slidably connected inside the limiting rods 7. Limiting support plates 9 are fixedly connected to the surface of the limiting springs 8. Lifting springs 10 are fixedly connected to the top of the inner wall of the limiting rods 7. Lifting crossbars 11 are fixedly connected to the bottom of the lifting springs 10. Adjusting screws 12 are threadedly connected to the top of the lifting crossbars 11. Connecting crossbars 13 are threadedly connected to the surface of the adjusting screws 12. When the adjusting screws 12 rotate inside the connecting crossbars 13, the lifting crossbars 11 can be driven to adjust the lifting position inside the limiting rods 7 in conjunction with the lifting springs 10. After the lifting springs 10 compress the limiting springs 8 and the limiting support plates 9, the position of the sampling hopper 1 can be adjusted back and forth inside the limiting rods 7, which increases the stability of the sampling hopper 1 after it moves to the appropriate position. The handle is long, and when receiving materials, the material receiving trough only needs to enter the weighing hopper side door, which effectively avoids accidents such as injury and the weighing hopper falling.

[0020] The lifting spring 10 and the adjusting screw 12, which are slidably connected inside the limiting pole 7, work together to ensure the rigid positioning after the screw is adjusted, and to absorb dynamic errors through the spring, thereby improving the accuracy of repeated sampling.

[0021] The connecting horizontal plate 13 is fixedly connected to the surface of the limiting upright 7. The number of limiting uprights 7 is set to two, and the two limiting uprights 7 are symmetrically distributed on the left and right sides with the sampling hopper 1 as the center.

[0022] The movable wheel 4 is located at the bottom of the sampling bucket 1, the surface of the limiting upright 7 is in contact with the left and right end surfaces of the sampling bucket 1, and the bottom of the limiting top plate 6 is in contact with the top surface of the support frame 5.

[0023] The push handle 2 is ergonomically designed and, together with the moving wheels 4, allows a single person to easily push the equipment to the sampling point. The plug-in structure of the support frame 5 and the limiting pole 7 supports quick disassembly, making it easy to clean or replace worn parts.

[0024] The number of lifting springs 10 and lifting crossbars 11 is set to two, and the two lifting springs 10 and lifting crossbars 11 are symmetrically distributed on the left and right sides with the sampling truck hopper 1 as the center.

[0025] The adjustable screws 12 are symmetrically distributed around the sampling hopper 1. By rotating the screws, the distance between the connecting horizontal plate 13 and the limiting upright 7 can be precisely adjusted, achieving millimeter-level control of the sampling port gap and adapting to the sampling needs of materials with different particle sizes.

[0026] The number of limiting springs 8 and limiting support plates 9 is set to four, with two in each group. The four limiting springs 8 and limiting support plates 9 are symmetrically distributed front and back around the limiting upright 7. A rigid frame is formed by inserting the support frame 5 into the limiting upright 7 to limit the lateral displacement of the sampling truck 1. The bottom of the limiting top plate 6 contacts the top of the support frame 5 to provide vertical limiting and ensure that the truck 1 maintains a stable posture under vibration or impact. The reinforcing crossbar 3 spans the surface of the sampling truck 1 and forms a triangular stable structure with the moving wheel 4 to prevent tipping. The moving wheel 4 is located at the bottom of the truck 1 to lower the center of gravity and improve the mobility.

[0027] The adjusting screw 12 is located at the bottom of the limiting top plate 6. The number of adjusting screws 12 is set to two, and the two adjusting screws 12 are symmetrically distributed on the left and right sides with the sampling hopper 1 as the center.

[0028] The implementation principle of the anti-blocking sampling port structure of the weighing bucket in this embodiment is as follows: When the adjusting screw 12 rotates inside the connecting horizontal plate 13, it can drive the lifting horizontal bar 11 to adjust its position inside the limiting upright 7 in conjunction with the lifting spring 10. After the adjustment is completed, the limiting spring 8 and the limiting support plate 9 of the lifting spring 10 can adjust the position of the sampling bucket 1 to the front and back inside the limiting upright 7, which increases the stability of the sampling bucket 1 after it moves to the appropriate position. The handle is long, and when receiving materials, only the receiving trough needs to enter the weighing bucket side door, which effectively avoids accidents that cause injury or the weighing bucket to fall. By setting the support frame 5 and the limiting upright 7 to form a rigid frame, the lateral displacement of the sampling bucket 1 is restricted. The bottom of the limiting top plate 6 contacts the top of the support frame 5 to provide vertical limitation, ensuring that the bucket maintains a stable posture under vibration or impact. The reinforced horizontal bar 3 spans the surface of the sampling bucket 1 and forms a triangular stable structure with the moving wheel 4 to prevent tipping. The moving wheel 4 is located at the bottom of the bucket, which lowers the center of gravity and improves the mobility.

[0029] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
