Description

Technical Field

[0001] This utility model relates to the field of sampling equipment, and in particular to a horizontal deep insertion sampling device and its application. Background Technology

[0002] Traditional motor vehicles are sampled from the top down, starting from the top of the cargo compartment. The sampling depth is generally no more than 3.5 meters. Therefore, the force is evenly distributed in this short sampling depth, and conventional sampling mechanisms can achieve this. However, when encountering containers and box trucks, sampling needs to be carried out from the rear of the cargo compartment, especially when the sampling depth is relatively deep. Currently, there are no special tools for sampling, and the market is still in a gap. Utility Model Content

[0003] The purpose of this utility model is to provide a horizontal deep insertion sampling device and its application. This horizontal deep insertion sampling device has advantages such as short single sampling time, stable and reliable operation, and a wide sampling depth range.

[0004] To achieve the above objectives, in a first aspect, this utility model provides a horizontal deep insertion sampling device, which includes: a support mechanism, a sampling mechanism, a clamping mechanism, a buffer mechanism, and a driving mechanism;

[0005] The support mechanism includes a support slide and at least three sets of guide rollers; the guide rollers are located within the support slide and each set of guide rollers is arranged opposite to each other;

[0006] The insertion mechanism includes a drill rod and a drill bit; the drill rod is slidably connected to the guide roller; the drill bit is located at the front end of the drill rod;

[0007] The clamping mechanism is located at the front of the support track and is sleeved on the outside of the drill rod, used to control the drooping deflection of the drill rod extending out of the support track;

[0008] The buffer mechanism is located at the rear of the support slide and is connected to the rear end of the drill rod; the buffer mechanism includes a buffer spring support frame, an adjusting bolt and a buffer spring, the buffer spring support frame is connected to the rear end of the drill rod, the adjusting bolt is fixed inside the buffer spring support frame, and the buffer spring is sleeved on the outside of the adjusting bolt;

[0010] Preferably, the horizontal deep insertion sampling device further includes a limiting mechanism;

[0011] The limiting mechanism is located at the rear of the support mechanism.

[0012] Preferably, the horizontal deep insertion sampling device further includes a fixing frame for accommodating the support mechanism.

[0013] Preferably, the specific spacing between each group of guide rollers is equal.

[0014] Preferably, the drive mechanism includes a DC motor, a coupling, a pair of drive sprockets, a drive spindle, a pair of driven sprockets, a driven spindle, and a chisel connector;

[0015] The driving spindle and the driven spindle are parallel and perpendicular to the support slide.

[0016] The coupling is connected to the DC motor and the drive spindle, respectively.

[0026] The horizontal deep-insertion sampling device provided in this embodiment of the utility model, through the setting of the drive mechanism, enables the insertion mechanism to achieve automatic sampling under the drive of the drive mechanism, saving labor costs and realizing the automation of sampling. The support slide and guide roller can play a supporting, guiding, positioning and correction role when the insertion mechanism is sampling in the horizontal direction, which greatly improves the sampling depth.

[0031] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Figure 1 A schematic diagram of the structure of the horizontal deep insertion sampling device provided in the embodiment of this utility model is shown below. Figure 1 As shown, the horizontal deep insertion sampling device specifically includes: a support mechanism 1, an insertion mechanism 2, a clamping mechanism 3, a buffer mechanism 4, and a drive mechanism 5.

[0033] The support mechanism 1 includes a support slide 11 and at least three sets of guide rollers 12. The support slide 11 includes vertically opposite slide rails 111. The support slide 11 can play a role in positioning and correction.

[0034] Guide rollers 12 are located within the support slide rails 11, and each group of guide rollers 12 is arranged opposite to each other. Each guide roller 12 in each group is fixed to a slide rail 111. In this application, there can be three pairs of guide rollers 12, with equal spacing between them. The guide rollers 12 can support and guide the insertion mechanism 2, and can also reduce the wear of the support friction surface.

[0035] The insertion mechanism 2 includes a drill rod 21 and a drill bit 22. The drill rod 21 and drill bit 22 can be integrally fixed or detachably connected; this application does not specifically limit this. The drill rod 21 is slidably connected to the guide roller 12. The drill bit 22 is located at the front end of the drill rod 21. Supported and guided by the guide roller 12, the insertion mechanism 2 can move horizontally forward and backward within the support slide 11. The drill rod 21 and drill bit 22 can be made of high-strength steel or alloy copper.

[0036] like Figure 2 As shown, the clamping mechanism 3 is located at the front of the support slide 11 and is sleeved on the outside of the drill rod 21. The clamping mechanism 3 mainly controls the sag deflection of the drill rod 21 extending out of the support slide 11, and also plays a role in reverse conveying by rolling friction when the drill rod 21 moves horizontally backward, which is conducive to the smooth retraction of the drill rod 21 and reduces the deformation of the drill rod 21. In this application, the sag deflection is no more than 10 mm.

[0037] Combination Figure 3 As shown, the buffer mechanism 4 primarily protects the insertion mechanism 2 during its backward movement. Specifically, the buffer mechanism 4 may include a buffer spring support frame 41, an adjusting bolt 42, and a buffer spring 43. The buffer spring support frame 41 is located at the rear of the support slide 11 and is connected to the rear end of the drill rod 21. The adjusting bolt 42 is fixed inside the buffer spring support frame 41, and the buffer spring 43 is sleeved on the outside of the adjusting bolt 42. When encountering a hard object or when the insertion resistance exceeds a preset value, the drill rod 21 transmits the resistance through the adjusting spring support frame 41 to the adjusting bolt 42, and further to the buffer spring 43. The buffer spring 43 compresses, thus protecting the insertion mechanism 2.

[0038] With the cooperation of the support mechanism 1, the clamping mechanism 3 and the buffer mechanism 4, the sampling depth of this horizontal deep insertion sampling device can be 0mm-6000mm.

[0039] The drive mechanism 5 is located outside the support slide 11 and is driven by the drill rod 21. It can drive the drill rod 21 to move back and forth along the axial direction of the support slide 11, thereby realizing the sampling.

[0040] In this application, the drive mechanism 5 may specifically include a DC motor 51, a coupling 52, a pair of drive sprockets 53, a drive spindle 54, a pair of driven sprockets 55, a driven spindle 56, and a chisel connector (not shown in the figure).

[0041] The drive spindle 54 and driven spindle 56 are parallel and perpendicular to the support slide rail 11. Coupling 52 is connected to both the DC motor 51 and the drive spindle 54. A pair of drive sprockets 53 are connected via the drive spindle 54. A pair of driven sprockets 55 are connected via the driven spindle 56. Each drive sprocket 53 is connected to each driven sprocket 55 via a chain. The chisel connector is connected to the chisel 21.

[0042] As a preferred embodiment, the horizontal deep insertion sampling device also includes a limiting mechanism 6. The limiting mechanism 6 is specifically located at the rear of the support slide 11. The limiting mechanism 6 can be a magnetic induction sensor or a mechanical limit switch. When the drill rod 21 reaches its travel position, the limiting mechanism 6 limits its movement. As an optional embodiment, such as... Figure 4 As shown, the horizontal deep insertion sampling device also includes a fixing frame 7. The support mechanism 1 is mounted on the fixing frame 7.

[0043] In one specific embodiment, the horizontal deep insertion sampling device also includes a pressure sensor (not shown in the figure). The pressure sensor is connected to a buffer spring 43. When encountering a hard object or when the sampling resistance exceeds a preset value during the sampling process, the pressure sensor can feed back the resistance to the host computer, allowing the host computer to promptly cut off the drive mechanism 5 and quickly reverse its operation to return, thus protecting the insertion mechanism 2. In another specific embodiment, the horizontal deep insertion sampling device also includes a lateral pressure sensor (not shown in the figure). The lateral pressure sensor is connected to the probe 21 to prevent the probe 21 from encountering a tension rod during sampling, thus preventing excessive lateral displacement and deformation.

[0044] The working frequency of the horizontal deep insertion sampling device can be 1.5 min / time.

[0045] The above describes the components of the horizontal deep insertion sampling device provided by the present invention and the connection relationship between the components. The working principle of the horizontal deep insertion sampling device is briefly described below.

[0046] The DC motor 51 receives the sampling command sent by the host computer and drives the drive spindle 54 to rotate clockwise through the coupling 52, thereby driving a pair of drive sprockets 53 to rotate, which in turn drives the chain to move forward. The chain drives the drill rod connector to move forward, and then drives the drill rod 21 to move forward horizontally under the support and guidance of the guide roller 12 and the support slide 11. The drill bit 22 extends out of the support slide 11, and at the same time, the limiting mechanism 6 limits it, and the clamping mechanism 3 clamps it, thereby performing sampling.

[0047] When the sampling depth is reached, the clamping mechanism 3 releases it. The DC motor 51 receives the sampling stop command sent by the host computer and drives the drive spindle 54 to rotate counterclockwise through the coupling 52, thereby driving a pair of drive sprockets 53 to rotate, which in turn drives the chain to move backward. The chain drives the drill rod connector to move backward, and then drives the drill rod 21 to move backward in the horizontal direction under the support and guidance of the guide roller 12 and the support slide 11. When the limiting mechanism 6 detects that the drill rod 21 has returned to its original position, it sends a signal to the host computer so that the host computer sends a stop command to the DC motor 51.

[0048] The horizontal deep-insertion sampling device provided in this embodiment of the utility model, through the setting of the drive mechanism, enables the insertion mechanism to achieve automatic sampling under the drive of the drive mechanism, saving labor costs and realizing the automation of sampling. The support slide and guide roller can support, guide, and position the insertion mechanism for sampling in the horizontal direction, which greatly improves the sampling depth. The clamping mechanism can greatly reduce the drooping deflection of the probe extending from the support slide, and when the probe moves horizontally backward, it also plays a role in reverse conveying by rolling friction, which is conducive to the smooth recovery of the probe and reduces the deformation of the probe. When encountering hard objects or when the sampling resistance exceeds the preset value, the probe transmits the resistance to the adjusting bolt through the adjusting spring support frame, and further to the buffer spring. The compression of the buffer spring can protect the insertion mechanism and improve the service life of the insertion mechanism.

[0049] The horizontal deep-insertion sampling device provided in this embodiment can be used for end sampling of materials in containers and vans.

[0050] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. 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.
