Description

Technical Field

[0001] This utility model relates to the field of sampling technology, and in particular to an automated sampling device. Background Technology

[0002] Traditionally, grain depots used manual sampling for sample collection. The sampler itself evolved into various forms (single-hole, with partitions, with sequential slots, etc.), primarily addressing the issue of sample uniformity. Later, various other types of samplers were developed, including rotary arm, truss, chute, and belt-driven sampling machines. Currently, grain depots still primarily use the single cantilever type. This sampler's main advantages are low cost and easy maintenance, but its disadvantages are also obvious: the unavoidable blind spot due to the rotation radius. Later, methods were developed to lengthen the rotary telescopic arm, but this still did not solve the blind spot problem, and manual intervention is still required during sampling.

[0003] In response to the problems with samplers in grain depots, how to achieve automated sampling has become a key research focus in the field of grain sampling. Utility Model Content

[0026] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] Figure 1 A schematic diagram of an automated sampling device provided in an embodiment of this utility model is shown below. Figure 1As shown, the automated sampling device specifically includes: a support frame 1, at least one set of transport components 2, at least one set of drill rod components 3, and an electronic wheel positioning component (not shown in the figure).

[0028] The support frame 1 is the supporting and fixing structure of the entire automated sampling device, and it may specifically include at least two sets of vertical beams 11 and one set of horizontal beams 12. The two sets of vertical beams 11 are parallel to each other and perpendicular to the ground. Each horizontal beam 12 is located at the top of a set of vertical beams 11, and a first guide rail 120 is provided on the top surface of each horizontal beam 12. The first guide rail 120 has limiting members (not shown in the figure), which may be provided at both ends of the first guide rail 120, and can be achieved by extending and bending the ends of the first guide rail 120 upwards.

[0029] As a preferred embodiment, to ensure the robustness and stability of the support frame 1, the support frame 1 also includes several stabilizing members 13, each of which is connected to a vertical beam 11 and a horizontal beam 12 respectively.

[0030] In an optional configuration, the support frame 1 further includes a detection platform 14. The detection platform 14 is located at the front end and / or rear end of the support frame 1.

[0031] Combination Figure 2 As shown, the carrier component 2 is the movement and bearing mechanism of the drill rod assembly 3, including at least one set of first carrier drive component 21, carrier component 22 and second carrier drive component 23.

[0032] Each first transport drive component 21 is slidably connected to a first guide rail 120, enabling the drill rod assembly 3 to move along the front-rear direction of the support frame 1. Figure 3 As shown, the first transport drive component 21 may specifically include a servo motor 210, a reducer 211, a drive spindle 212, a track wheel 213, a bearing housing 214, and a housing 215. The reducer 211 is connected to the servo motor 210. The drive spindle 212 is connected to the reducer 211. The track wheel 213 passes through the drive spindle 212 and is slidably connected to the first guide rail 120. The bearing housing 214 is located on one side of the track wheel 213 and connected to the drive spindle 212, providing a limiting position for the track wheel 213. The housing 215 covers the outside of the track wheel 213, providing dust protection for the first transport drive component 21.

[0033] In one specific example, the first transport drive 21 also includes an anti-derailment device 216. The anti-derailment device 216 is fixed to the side of the housing 215 and can prevent the track wheel 213 from derailing during movement along the first guide rail 120.

[0034] The operating speed of the first carrier drive unit 21 is ≥0.5m / s.

[0035] The carrier component 22 is the main fixing component of the drill rod assembly 3. (Combined) Figure 2 As shown, the carrier 22 may specifically include a second guide rail bracket 221. The bottom surface of the second guide rail bracket 221 is fixed to the top surface of the two first carrier drive components 21, mainly for accommodating the second guide rail 220. The projection of the second guide rail 220 is perpendicular to the projection of the first guide rail 120. The length of the second guide rail bracket 221 matches the distance between a set of crossbeams 12. One end of the second guide rail bracket 221 is fixed to the top of one first carrier drive component 21, and the other end is fixed to the top of another first carrier drive component 21, thus fixing the carrier 22 to a set of first carrier drive components 21, specifically to the top of the housing 215, and allowing it to move along the first guide rail 120 under the drive of the first carrier drive components 21.

[0036] Combination Figure 4 As shown, the second guide rail bracket 221 also has a through hole 2210, which is mainly used for the insertion of the drill rod assembly 3.

[0037] The carrier component 22 also has a roller mechanism 222. The roller mechanism 222 includes a roller support frame 2220 and rollers 2221. The roller support frame 2220 is the main connection mechanism between the second carrier drive component 23 and the drill rod assembly 3. The roller support frame 2220 is located in the through hole 2210 and has a connecting rod 22201 and a hook (not shown in the figure). The connecting rod 22201 is mainly used for the fixed installation of the drill rod assembly 3, and the hook is used for connection with the carrier drive mechanism 23. The rollers 2221 are connected to the roller support frame 2220.

[0038] For example Figure 2 As shown, in a preferred embodiment, the carrier 22 further includes a cable chain 223, which is a receiving mechanism for the wires of the drill rod assembly 3 and the second carrier drive 23.

[0039] The second transport drive component 23 is the main drive mechanism for the left and right movement of the drill rod assembly 3 along the support frame 1. It is fixed to the top of the second guide rail bracket 221. The second transport drive component 23 may specifically include a variable frequency motor 231, a sprocket 232, and a chain 233. The sprocket 232 is connected to the output shaft of the variable frequency motor 231, the chain 233 is connected to the sprocket 232, and the chain 233 is connected to the roller support frame 2220 through a hook.

[0040] For example Figure 1 As shown, the drill rod assembly 3 is the main component for sampling. Each drill rod assembly 3 may specifically include a drill rod holder 31, a drill rod 32, and a rangefinder 33. The drill rod 32 is inserted into the drill rod holder 31. The rangefinder 33 is fixed to the bottom end of the drill rod holder 31, and may be an infrared rangefinder or a laser rangefinder.

[0041] The drill rod fixing frame 31 is connected to the roller support frame 2220 via the connecting rod 22201. Under the drive of the second transport drive component 23, the roller mechanism 222 moves along the second guide rail 220, driving the drill rod 32 to move, thereby realizing the left and right movement of the drill rod 32 along the support frame 1.

[0042] The electronic wheel positioning component is located within the ground area corresponding to the support frame 1, and is mainly used to detect whether the vehicle to be sampled is in place.

[0043] The above describes the components of an automated sampling device and the composition of each component. The working principle of the automated sampling device is briefly described below.

[0044] When the electronic wheel positioning device detects the arrival of the vehicle to be sampled, it generates a vehicle arrival signal and sends it to an external host computer. The host computer generates control commands based on the vehicle arrival signal and sends them to an external PLC controller. The PLC controller generates a first control signal and sends it to the first transport drive unit 21, and generates a second control signal and sends it to the second transport drive unit 23. Driven by the first transport drive unit 21 and the second transport drive unit 23, the rangefinder 33 moves in a direction parallel to the first guide rail 120 and parallel to the second guide rail 220. The direction of movement determines the carriage data of the vehicle to be sampled and sends it to the host computer. The host computer generates sampling coordinate values ​​based on the carriage data of the vehicle to be sampled and sends the sampling coordinate values ​​to the PLC controller. The PLC controller controls the first transport drive component 21 to move along the first guide rail. The chain 233 of the second transport drive component 23 drives the roller support frame 2220 to move through the grab hook, thereby driving the roller 2221 to move along the second guide rail 220, so that the drill rod 32 reaches the sampling position corresponding to the sampling coordinate value, and the sampling is realized.

[0045] This utility model provides an automated sampling device that identifies the vehicle to be sampled using an electronic wheel positioning component. Then, a first transport drive component drives the transport component to move along a first guide rail, thereby enabling the drill rod assembly fixed on the transport component to move along the front-back direction of the support frame. A second transport drive component drives rollers to move along a second guide rail, thereby enabling the drill rod assembly to move along the left-right direction of the support frame. This achieves automated front-back and left-right movement of the drill rod for sampling. The process requires no manual intervention. The modular design allows for rapid installation and strong scalability; for example, it can be used in parallel or serial modes (e.g., sampling grain transported by train).

It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
