Abstract
Description
Technical Field
[0001] The present application relates to the technical field of sampling tools, and in particular to a material sampling device. Background Art
[0002] With the change in the way wood chips are unloaded, from being unloaded onto the ground to being unloaded directly into the tunnel using a flap machine, a single-stage unloading and loading operation has been achieved. This has significantly reduced intermediate links and reduced operating costs, but it has also brought a new challenge: sampling. The original method allowed manual shoveling of samples directly from the wood chip pile after unloading. However, with the flap machine, sampling is required during the unloading process. During the unloading process, wood chips slide rapidly and have a strong impact. If samples are still scooped manually with a shovel, the shovel will be dislodged due to insufficient support, posing a significant safety risk to both personnel and equipment.
[0003] For small particles, a grating can be added to the feed opening of a plate-turning machine. The material then falls through the gaps in the grating and into the opening, allowing the sampler to collect the material by touching the grating. However, this method is not suitable for wood chips, which are bulky and require a large grating to pass through, otherwise it is prone to blockage. Alternatively, the wood chips can be sampled on the belt after they fall into the tunnel and are carried out by the spiral. However, this method only allows one plate-turning machine to be used for each feed opening. If the material from two plate-turning machines falls into the same opening, the wood chips will be mixed and the corresponding vehicle's wood chips will not be collected. Utility Model Content

The carrying vehicle can slide along the track, one end of the probe rod is connected to the carrying vehicle, and the other end is connected to the sampling shovel. The carrying vehicle drives the sampling shovel to move through the probe rod, and then drives the sampling shovel to extend and retract for sampling.

The carrier 200 drives the sampling shovel 400 to move back and forth in the direction of the arrow in the figure via the probe rod 300, thereby driving the sampling shovel 400 to extend and retract the sampling shovel. In this embodiment, the track 100, carrier 200, probe rod 300, and sampling shovel 400 can all be made of wear-resistant and impact-resistant materials such as stainless steel.
[0025] Optionally, continue with Figure 1 and Figure 2 The material sampling device in this embodiment further includes a push rod 500, which is connected to the carrier 200 and is used to push the carrier 200 to slide along the track 100. The push rod 500 may specifically include a connecting rod 510 and a handle 520, and the operator pushes the push rod 500 through the handle 520.
[0026] Please also refer to Figure 3 , Figure 3 yes Figure 2 The material sampling device of the embodiment is a schematic cross-sectional view of the structure along AA, wherein the track 100 of this embodiment includes a first track 110 and a second track 120 arranged in parallel, and the spacing between the first track 110 and the second track 120 can be 20-30 cm. The carrier 200 moves along the first track 110 and the second track 120 at the same time. Please continue to refer to Figure 2 The first rail 110 and the second rail 120 may be connected at both ends by a crossbeam 130. Furthermore, the crossbeam 130 may be used to securely connect to external equipment or an operating surface. Furthermore, anti-drop rods (not shown) may be welded to the bottoms of the first rail 110 and the second rail 120.
[0027] Optionally, in this embodiment, the first rail 110 and the second rail 120 both have an I-shaped cross-section, i.e., are made of I-beam steel. The bottom of the carrier 200 is provided with a plurality of rotating wheels 210 that can slide along the first rail 110 and the second rail 120. The rotating wheels 210 include an integrally structured supporting roller 211 and a guide roller 212. The guide roller 212 is provided at one end of the supporting roller 211 and is located inside the first rail 110 and the second rail 120, and is used to guide the carrier 200 to prevent the carrier 200 from deviating from the first rail 110 and the second rail 120.
[0028] Optionally, there may be multiple sampling shovels 400 in this embodiment, and one of them may be detachably connected to the probe rod 300 to replace sampling shovels 400 of different specifications. The operator may replace sampling shovels 400 of different sizes or shapes according to the different sampling materials.
[0029] Please also refer to Figure 1 、 Figure 2 as well as Figure 4 , Figure 4 yes Figure 2 An enlarged schematic diagram of the local structure at point B in the embodiment shows that the probe rod 300 in this embodiment is a hollow tubular structure, and a buckle 304 is provided at the end. The sampling shovel 400 may include a connecting handle 410 and a shovel head 420. At least part of the structure of the connecting handle 410 is inserted into the probe rod 300.

The main arm 310 is connected to the carrier 200 and the sampling shovel 400 at both ends, respectively. The reinforcement arm 320 is located on the top of the main arm 310. The reinforcement arm 320 can be an arc-shaped structure, with its two ends connected to the main arm 310. Multiple connecting arms 330 can be provided between the reinforcement arm 320 and the main arm 310. Because the main arm 310 of the probe rod 300 has a relatively long cantilever length, the design of the reinforcement arm 320 and the connecting arm 330 can improve the bending resistance of the probe rod 300, thereby improving its overall strength and stability.
[0031] The material sampling device provided in the embodiment of the present application is mainly designed for the characteristics of fast sliding speed and strong impact of wood chips during unloading. The material sampling device includes a fixed guide rail, a carrying vehicle, a probe rod and a sampling shovel, so that the impact force of the sampling process is transferred to the material sampling device instead of relying on manpower to resist the impact, thereby avoiding safety risks during the operation.
