Description

Technical Field

[0001] The utility model relates to the technical field of solid waste sampling, in particular to a portable solid waste sampling device. Background Art

[0002] In the process of agricultural product quality and safety testing, forestry product quality inspection and testing, and indoor environment testing, it is usually necessary to use a sampling device to sample solid waste in order to detect the impact of solid waste on the surrounding soil and conduct analysis. For example, in the patent with the announcement number "CN216160197U" and the name "A Sampling Device for Solid Waste Monitoring", a motor is connected to a support frame, the free end of the output shaft of the motor is sleeved on the upper end of the drill rod, a plug is filled in the through hole, and the drill bit is connected to the first threaded hole on the connecting flange through a screw. The motor drives the drill rod and the drill bit to rotate, completing the drilling of the soil. When the drill rod reaches the specified depth, the drill rod is pulled out, the drill bit and the plug are removed, and the drill bit is reconnected to the lower end surface of the drill rod. Since the plug is not filled in the through hole, the drill rod is reinserted into the already drilled hole, and the motor drives the drill bit to rotate again through the drill rod. During the drilling process, some soil is squeezed into the through hole. The drill rod is pulled out to remove the soil squeezed into the through hole, completing the sampling of soil or solid waste buried at a certain depth. However, the above structure still has the following problems during actual use:

[0003] The above connection drives the drill rod and the drill bit to rotate through a motor, and then the soil squeezed into the through hole is taken out by pulling out the drill rod, thereby completing the sampling of soil or solid waste buried at a certain depth. However, the sampling method driven by a motor causes the device to be relatively large. When it is necessary to sample agricultural products, forestry or indoor solid waste, the device is too large and will cause inconvenience in carrying, which in turn affects the staff's use of the device for sampling, making it not portable during use and having poor practicality.

[0004] Therefore, we proposed a portable solid waste sampling device that can solve the above problems well. Utility Model Content

[0005] The purpose of the present utility model is to provide a portable solid waste sampling device to solve the problem raised in the above background technology that the devices currently on the market are relatively large. When it is necessary to sample agricultural products, forestry or indoor solid waste, the device is too large to be carried, which in turn affects the staff's use of the device for sampling, making it not portable enough and less practical during use.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a portable solid waste sampling device, comprising a device body and a limiting plate arranged on the outside of the device body for supporting and limiting;

[0007] The device further comprises: a limiting block is fixed on the inner side of the limiting plate, and a sliding connection is formed between the limiting block and the device body, and the upper surface of the left limiting block is fixed to one end of a connecting rod, and the other end of the connecting rod extends out of the upper end surface of the device body and forms a sliding connection with the device body;

[0008] One side of the connecting rod is provided with tooth blocks at equal intervals vertically, and one side of the tooth block is provided with a driving mechanism, which drives the spiral blades through the vertical rod to achieve the sampling effect.

[0009] Preferably, the driving mechanism includes a gear and a rotating shaft, wherein the gear and the gear block form a meshing connection, and the rotating shaft is fixed in the middle of the gear, and both ends of the rotating shaft are connected to the device body bearing.

[0010] Preferably, a bevel gear set is fixed to one end of the rotating shaft, and the bevel gear set is composed of two sets of bevel gears forming a linkage structure, wherein one set of bevel gears is fixed to the rotating shaft, and the other set of bevel gears is fixed to the worm.

[0011] Preferably, the outer side of the worm is meshed with the worm wheel, and a vertical rod is fixed in the middle of the worm wheel, and the upper end of the vertical rod is placed on the upper surface of the device body, and the lower end of the vertical rod passes through the lower end opening of the device body.

[0012] Preferably, the vertical pole and the device body are in a rotationally connected structure, and a spiral blade is fixed to the outer side of the vertical pole, and the outer side of the spiral blade is in contact with the inner wall of the device body.

[0013] Preferably, a sampling port is provided on the front side of the device body, and the lower end of the device body is arranged in an inclined structure.

[0014] Preferably, a scale is provided on the outside of the device body, and the length of the scale is smaller than the device body.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the portable solid waste sampling device does not need to use a separate electric drive to provide driving force, thereby controlling the weight of the device and avoiding the device being too heavy and bulky to affect transportation, thereby making it easier for workers to hold the device for sampling, improving portability, and facilitating the discharge of fixed waste in the middle section of the spiral blade, and facilitating the reset of the device for next use. The specific contents are as follows:

[0016] (1) The worm drives the worm wheel to rotate, and the worm wheel drives the vertical rod to rotate together, and the vertical rod drives the spiral blade to rotate together, so that the fixed waste in the lower layer is sent to the upper part through the spiral blade, and finally the sampling is completed by sampling through the sampling port. The process is simple and convenient, and there is no need to use electric driving force alone, so the weight of the device can be controlled, avoiding the device being too heavy and affecting transportation, making it easier for staff to hold the device for sampling, thereby improving portability;

[0017] Furthermore, the limit plate contacts the solid waste. When the device body is further pressed downward, the device body will slide into the fixed waste, causing the limit plate to slide upward through the limit block. At the same time, when the limit block moves upward, it also drives the connecting rod to move together, so that the connecting rod drives the meshing gear to rotate together through the tooth block.

[0018] Furthermore, the gear rotates, thereby driving the fixed shaft to rotate together, and the rotation of the shaft simultaneously drives the bevel gear set to rotate together, and the bevel gear set drives the worm to rotate together, thereby increasing the power of the device;

[0019] When sampling is completed, it is only necessary to pull out the device body, so that the limit plate drives the connecting rod downward through the limit block, and the connecting rod drives the gear to reverse through the tooth block, and the rotating shaft drives the worm to reverse through the bevel gear set, so that the worm gear drives the vertical rod and the spiral blade to reverse together, so that the fixed waste in the middle section of the spiral blade is discharged and the device is reset for the next use;

[0020] By setting the scale, it is easy to observe the insertion depth of the device body, which makes it easier for staff to control and know, and thus facilitates sampling of fixed waste at different depths, thereby making sampling diverse and more conducive to staff sampling and testing fixed waste at different depths, improving the detection effect, and solving the problem of being unable to know the depth of the sample taken in the existing technology.

[0030] In order to solve the problem that the device proposed in the prior art is relatively large, when it is necessary to sample agricultural products, forestry or indoor solid waste, the device is too large, which will cause inconvenience in carrying, thereby affecting the staff's use of the device for sampling, making it not portable and less practical during use, the following solution is disclosed, including a device body 1 and a limit plate 2 arranged on the outside of the device body 1 for supporting and limiting; it also includes: a limit block 3 is fixed on the inner side of the limit plate 2, and a sliding connection is formed between the limit block 3 and the device body 1, and at the same time, the upper surface of the left limit block 3 is fixed to one end of the connecting rod 4, and the other end of the connecting rod 4 is fixed to the left side of the limit block 3.
