[0002] Downhole drilling rigs are important equipment used for geological exploration and mineral mining. They can drive the drilling tools to break rocks in the underground environment and drill cores, mineral cores, gas samples, liquid samples, etc., to explore the underground geological and mineral resources.

[0003] According to CN217760867U, a downhole drilling rig is disclosed. This technology discloses a technical solution such as "a downhole drilling rig, including a traveling mechanism, a working mechanism, and a drill frame; wherein the working mechanism includes: a rotary worktable disposed on the traveling mechanism for adjusting the rotation angle of the drill frame in the horizontal direction; a bracket fixedly installed on the rotary worktable, the bracket being hinged to the mounting seat of the drill frame; and a longitudinal angle adjustment mechanism for adjusting the included angle between the drill frame and the bracket". This technology has the technical effect of "effectively avoiding the aerial delivery pipes on the inner wall of the roadway and the belt conveyor line on the ground while drilling, resulting in higher work efficiency".

[0004] After sampling, downhole drilling rigs need to classify and collect the samples for subsequent analysis. However, existing classification and collection devices often only have the function of collection and lack the ability to screen the samples. This results in the collected samples containing particles of different sizes, which brings inconvenience to subsequent analysis. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a convenient sampling and sorting collection device for downhole drilling rigs. It features a motor output that drives an eccentric circle to rotate, which in turn drives a coarse screen, a fine screen, and a material plate to vibrate slightly via a first, second, and third connecting rod, respectively. This allows the sample to be sorted into three categories for collection after two sieving processes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sorting and collection device for downhole drilling rigs that facilitates sampling, comprising a frame, wherein a collection mechanism is provided on the frame for sorting and collecting the samples after sampling, the collection mechanism comprising:

[0014] Beneficial effects

[0015] This invention provides a convenient sorting and collection device for downhole drilling rigs. Compared with the prior art, it has the following advantages:

[0016] (1) When the sample enters the sieving box through the feed inlet, the eccentric circle is driven to rotate by the output end of the motor. The eccentric circle drives the coarse screen, fine screen and material plate to vibrate slightly through the first connecting rod, the second connecting rod and the third connecting rod respectively, so that the sample is divided into three categories for collection after two sievings.

The collection mechanism 2 includes:

[0025] The main component 21 includes a screening box 211 fixed on the frame 1. Inside the screening box 211, a coarse screen 212, a fine screen 213 and a material plate 214 are hinged at equal intervals from top to bottom. A motor 226 is installed on the screening box 211, and the output end of the motor 226 is fixed to the axis of the eccentric circle 222.

[0026] The drive assembly 22 includes a bearing 221 fixed to the outer wall of the left end of the screening box 211, an eccentric circle 222 rotatably mounted on the bearing 221, and a first connecting rod 223, a second connecting rod 224, and a third connecting rod 225 rotatably mounted on the outer edge of the eccentric circle 222. The other ends of the first connecting rod 223, the second connecting rod 224, and the third connecting rod 225 are respectively pivotally connected to the left end of the coarse screen 212, the fine screen 213, and the material plate 214.

[0027] In this embodiment, when the sample enters the sieving box 211 through the feed inlet 219, the output end of the motor 226 drives the eccentric circle 222 to rotate. The eccentric circle 222 drives the coarse screen 212, the fine screen 213 and the material plate 214 to vibrate slightly through the first connecting rod 223, the second connecting rod 224 and the third connecting rod 225 respectively, so that the sample is divided into three categories for collection after two sievings.

[0028] Specifically, the main component 21 also includes a collection box 215 fixed to the right end of the screening box 211, three discharge ports 216 opened at the right end of the screening box 211, and three collection slots 217 inserted and installed inside the collection box 215, with the three collection slots 217 located below the three discharge ports 216 respectively.

[0029] In this embodiment, the samples on the coarse screen 212, fine screen 213 and material plate 214 can fall into the three collection tanks 217 through the three discharge ports 216 respectively for collection.

[0030] Specifically, the main component 21 also includes a waste trough 218 inserted into the lower end of the screening box 211 and a feed inlet 219 fixed to the top of the screening box 211.

[0031] In this embodiment, the residue of the sample falling to the sides during the sieving process inside the sieving box 211 can fall into the waste trough 218 for collection.

[0032] Specifically, the collection mechanism 2 also includes three slots 23 opened at the left end of the screening box 211 and a window 24 fixed inside the rear end of the collection box 215.

[0033] In this embodiment, the collection status of the sample inside the collection box 215 can be observed through the window 24, making it convenient to remove the sample before the collection tank 217 is full.

[0035] In this embodiment, the drilling mechanism 3 takes samples through the sampling mechanism 4 during the drilling process, and the sand pump 5 transports the samples from the pipeline 6 to the collection mechanism 2.

[0036] The working principle and usage process of this utility model are as follows: First, during the drilling process, the drilling mechanism 3 takes samples through the sampling mechanism 4, and the sand pump 5 transports the samples from the pipeline 6 to the collection mechanism 2. When the samples enter the sieve box 211 through the feed inlet 219, the output end of the motor 226 drives the eccentric circle 222 to rotate. The eccentric circle 222 drives the coarse screen 212, the fine screen 213 and the material plate 214 to vibrate slightly through the first connecting rod 223, the second connecting rod 224 and the third connecting rod 225 respectively. This allows the samples on the coarse screen 212, the fine screen 213 and the material plate 214 to fall into the three collection tanks 217 through the three discharge ports 216 respectively, so that the samples are divided into three categories for collection after two sieves.
