Description

Technical Field

[0001] The utility model relates to the field of collection and sampling, in particular to a device for quantitatively taking trace elements. Background Art

[0002] Trace elements refer to the elements whose content in human body is between 0.01% and 0.005% of body weight. Essential trace elements are indispensable elements for organisms, such as iron, copper, zinc, cobalt, chromium, manganese and selenium. These elements cannot be produced and synthesized in the body and need to be provided by food. Deficiency of trace elements will lead to various diseases. Therefore, the intake of trace elements in the environment is closely related to human body and has great significance for human health.

[0003] After searching, a Chinese patent discloses a forestry soil trace element quantitative collection sampling device (publication number CN211262756 U). The patent technology has the advantages of easy operation, flexible use, and convenient for direct quantitative operation during the sampling process. However, the technical solution of the above patent document uses a movable buckle to perform temporary resistance limiting and control the depth, which makes it easy to take too much samples and requires constant lowering of the head to observe the scale, making it more troublesome to realize the quantitative operation of trace element sampling and detection.

[0004] Therefore, a device for quantitatively taking trace elements is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a device for quantitatively taking trace elements in order to solve the above-mentioned problems, which improves the problem that the temporary resistance limit is performed by a movable buckle to control the depth, it is easy to take too many samples, and it is necessary to constantly look down to observe the scale, which makes the quantitative operation of sampling and detecting trace elements more troublesome.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions. A device for quantitatively taking trace elements includes: a driving component, wherein the output end of the driving component is fixedly connected to a collecting component, the circumferential surface of the collecting component is rotatably connected to a connecting frame, both ends of the connecting frame that are parallel to each other are fixedly connected to a sliding rod, and the surface of the sliding rod is slidably connected to a leg; an adjusting mechanism is used to set the contraction length of the sliding rod and the leg, and the adjusting mechanism for facilitating quantitative collection by the collecting component is arranged on one side of the sliding rod; a locking component is used to lock the set length of the adjusting mechanism, and the locking component that prevents the set length from being shortened due to downward pressure is arranged on one side of the sliding rod; wherein the adjusting mechanism includes a height-fixing component arranged on one side of the sliding rod, and a synchronization component is arranged on one side of the height-fixing component.

[0007] Preferably, two groups of the height-fixing components are provided, and each group of the height-fixing components includes a lead screw rotatably connected to the lower inner wall of the sliding rod, the upper end of the lead screw rotates through the upper end of the sliding rod and extends upward, the surface of the lead screw is threadedly connected with a square nut, and the side end of the square nut is fixedly connected with a height-fixing block. The sampling depth can be set through the height-fixing component. When it is pressed down to the sampling depth, it will be blocked and stop automatically to prevent excessive sampling. There is no need for multiple observations, which is more convenient.

[0008] Preferably, the square nut is slidably connected to the inner wall of the slide rod, and the square nut fits closely to the inner wall of the slide rod. When the sampling depth is adjusted, the square nut can easily rotate synchronously with the rotation of the lead screw, so that the square nut slides in the slide rod. The two fit closely together and there is no shaking gap, so that the square nut slides more stably in the slide rod.

[0009] Preferably, the height setting component also includes an indicator rod fixedly connected to the side end of the height setting block, and the side end of the sliding rod is provided with scale lines. The indicator rod slides in contact with the scale line surface.

[0011] Preferably, the locking assembly includes a gear fixedly connected to the surface of the screw, the side end of the sliding rod is fixedly connected to a mounting block, the mounting block is fixedly connected to a spring near the side end of the sliding rod, one end of the spring is fixedly connected to a fitting block, the fitting block fits the surface of the gear, and the adjustment scale of the height setting assembly can be locked by the locking assembly to prevent shaking and downward pressure when pressing down, which causes the screw to rotate automatically and causes the set depth to change automatically.

[0012] Preferably, a pull rod is fixedly connected to the side end of the fitting block, one end of the pull rod movably passes through the mounting block and extends outward, and the spring is sleeved on the circumferential surface of the pull rod. When the fitting block is pushed by the spring to fit the gear surface, the spring is prone to elastic deformation and damage.

[0013] Preferably, one end of the pull rod is fixedly connected to a pull block, the side end of the mounting block is fixedly connected to a guide rod, and the surface of the guide rod is slidably connected to a blocking block, through which the blocking block can slide between the mounting block and the pull block to prevent the pull block and the fitting block from retreating, so that the lead screw can rotate by itself for easy adjustment.

[0014] The beneficial effects of the utility model are:

[0015] 1. When using this device to collect soil containing trace elements, first, the height-fixing component can be unlocked through the locking component, and then the height-fixing component can be rotated to adjust the set pressing height. The synchronization component drives the two height-fixing components to adjust synchronously, which is convenient for use. After the height-fixing component is adjusted to a suitable depth, the height-fixing component can be locked by the locking component. At this time, the driving component is started to drive the collection component to rotate to sample the soil. After pressing down to the set depth, it stops and cannot descend, completing the quantitative acquisition of samples;

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] When implementing: Figure 1-4As shown, a device for quantitatively taking trace elements comprises: a driving component 1, wherein the output end of the driving component 1 is fixedly connected to a collecting component 3, the circumferential surface of the collecting component 3 is rotatably connected to a connecting frame 2, both ends of the connecting frame 2 being parallel to each other are fixedly connected to slide bars 5, and the surface of the slide bars 5 is slidably connected to legs 6; an adjusting mechanism 4, which is used to set the contraction length of the slide bars 5 and the legs 6, and the adjusting mechanism 4 for facilitating quantitative collection by the collecting component 3 is arranged on one side of the slide bar 5; a locking component 7, which is used to lock the set length of the adjusting mechanism 4, and prevent the locking component 7 from being shortened due to downward pressure, and is arranged on one side of the slide bar 5; wherein the adjusting mechanism 4 comprises a height-fixing component 401 arranged on one side of the slide bar 5, and a synchronization component 402 is arranged on one side of the height-fixing component 401. When the device is used to take and collect land containing trace elements, the locking component 402 can be used to lock the adjusting mechanism 4. Component 7 unlocks the height-fixing component 401, and then adjusts the set pressing height by rotating the height-fixing component 401. The synchronization component 402 drives the two height-fixing components 401 to adjust synchronously, which is convenient for use. After the height-fixing component 401 is adjusted to the appropriate depth, the adjusted depth of the height-fixing component 401 can be locked by the locking component 7. At this time, the driving component 1 is started to drive the collecting component 3 to rotate to sample the soil. After pressing down to the set depth, it stops and cannot descend, completing the quantitative acquisition of samples. The lower side of the leg 6 has an adjustable foot cup, which can be finely adjusted in height so that it can be placed on an uneven land surface. The driving component 1 includes an upper hand frame and an installed driving motor. The collecting component 3 includes a rotating rod and a sampling drill bit. The driving component 1 and the collecting component 3 have the same structure as the driving and sampling parts in the comparative document, and no further details are given here.

[0024] like Figure 3 and Figure 4As shown, two groups of height-fixing components 401 are provided, and each group of height-fixing components 401 includes a lead screw 4011 rotatably connected to the lower inner wall of the slide bar 5, the upper end of the lead screw 4011 rotates to penetrate the upper end of the slide bar 5 and extends upward, a square nut 4012 is threadedly connected to the surface of the lead screw 4011, and a height-fixing block 4015 is fixedly connected to the side end of the square nut 4012. When it is necessary to adjust the telescopic distance between the slide bar 5 and the support leg 6, the lead screw 4011 can be rotated at this time, so that the lead screw 4011 drives the square nut 4012 moves, and the square nut 4012 drives the height-fixing block 4015 to move to the set height. When the slide bar 5 is pressed down to the set height, it will be blocked by the height-fixing block 4015 and cannot go down, completing the sample collection at the set height. The square nut 4012 is slidably connected to the inner wall of the slide bar 5, and the square nut 4012 fits the inner wall of the slide bar 5 more closely. When the lead screw 4011 rotates to drive the square nut 4012 to move, the square nut 4012 is easy to shake with the rotation of the lead screw 4011. The square nut 4012 fits with the inner wall of the slide bar 5, so that the square nut 4012 has no gap for rotation and shaking, so that the square nut 4012 cannot rotate, which is more stable. The height setting component 401 also includes an indicator rod 4014 fixedly connected to the side end of the height setting block 4015. The side end of the slide bar 5 is provided with a scale line 4013. The indicator rod 4014 slides and contacts the surface of the scale line 4013. When the height setting block 4015 moves, it will drive the indicator rod 4014 to slide on the surface of the scale line 4013. The dynamic indicating scale is convenient for observing the set length during adjustment. The synchronous component 402 includes a synchronous belt 4022 and two toothed pulleys 4021 fixedly connected to the surfaces of the two lead screws 4011. The two toothed pulleys 4021 are meshed and driven by the synchronous belt 4022. When the lead screw 4011 rotates, the toothed pulley 4021 is driven to rotate. At this time, the synchronous belt 4022 is used to make the two toothed pulleys 4021 rotate at the same time, making the adjustment more convenient and driving the two height-fixing components 401 at the same time to reduce the adjustment error.

[0025] like Figure 3As shown, the locking assembly 7 includes a gear 701 fixedly connected to the surface of the screw 4011, a mounting block 702 is fixedly connected to the side end of the slide bar 5, and the side end of the mounting block 702 close to the slide bar 5 is fixedly connected to a spring 703, and one end of the spring 703 is fixedly connected to a fitting block 704, and the fitting block 704 fits the surface of the gear 701. When the rotation setting of the screw 4011 is completed, the height setting block 4015 is pressed down to easily push the screw 4011 to rotate by itself, and the fitting block 704 is pushed to fit the surface of the gear 701 by the spring 703, so that the fitting block 704 is not easy to rotate by itself, so that the set length is more stable and not easy to change by itself. The side end of the fitting block 704 is fixedly connected to a pull rod 705, and one end of the pull rod 705 movably penetrates the mounting block 705. The mounting block 702 extends outward, and the spring 703 is sleeved on the circumferential surface of the pull rod 705. When the spring 703 pushes the fitting block 704 to fit the surface of the gear 701, the spring 703 is prone to lateral elastic deformation and damage. At this time, the spring 703 is supported by the pull rod 705, so that the spring 703 is not prone to lateral elastic deformation and damage during the compression and relaxation process. One end of the pull rod 705 is fixedly connected to a pull block 706, and the side end of the mounting block 702 is fixedly connected to a guide rod 707. The surface of the guide rod 707 is slidably connected to a blocking block 708, which can slide between the mounting block 702 and the pull block 706 to prevent the pull block 706 and the fitting block 704 from retreating, so that the screw 4011 can rotate by itself, which is convenient for adjustment.

[0026] When the utility model is in use, when the device is used to collect soil containing trace elements, the fitting block 704 can be moved away from the gear 701 by pulling the pull block 706, and the blocking block 708 can be inserted into one side of the pull block 706 to block the retreat, and then the height of the height-fixing block 4015 can be adjusted by rotating the lead screw 4011. At this time, the height-fixing block 4015 is adjusted to a suitable height through the scale line 4013 and the indicating scale of the indicator rod 4014. When the lead screw 4011 rotates, it will drive the toothed belt wheel 4021 to rotate, and the two toothed belt wheels 4021 will rotate at the same time through the synchronous belt 4022, and the two sets of height-fixing wheels will be driven at the same time. Component 401 is adjusted. At this time, after the height-fixing component 401 is adjusted, the blocking block 708 is pulled, so that the spring 703 pushes the fitting block 704 to fit the surface of the gear 701, and the rotation of the lead screw 4011 is locked. At this time, the placement stability is adjusted by the support legs 6, and then the drive component 1 is started to drive the collection component 3 to collect the soil sample containing trace elements. At this time, the collection component 3 is continuously lowered by the downward pressure. When it reaches the set height, it is blocked by the height-fixing block 4015 and cannot fall. At this time, the collection component 3 quantitatively collects the soil containing trace elements. During the collection process, there is no need to lower your head to check the height. It is more convenient to press down and stop after reaching the set height.

[0027] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
