Portable grassland biomass measurement sampler

Abstract

The utility model provides a portable grassland biomass measuring sampler which aims at efficiently and conveniently completing grassland biomass sampling and measuring work. The sampler takes a sampler shell as a main body, a servo motor is fixed in the center of a top plate, and the motor drives a motor rotating shaft to rotate so as to drive a sampling spiral blade connected with the rotating shaft to drill into grassland soil, so that sample collection is realized. A collected sample ascends along the spiral blade, enters the sampling tube, is buffered by the buffer wheel and then reaches the interior of the sampler shell. A sample outlet stirring blade on a rotating shaft of the motor is used for stirring the sample to a discharge hole, and impurities are filtered through a flowing pipeline with filter screen holes.

Description

TECHNICAL FIELD

[0001] The utility model relates to a sampler technical field, specifically, relates to a portable grassland biomass determination sampler. BACKGROUND

[0002] In the field of grassland ecological research, agricultural production and environmental monitoring, accurate determination of grassland biomass is crucial, as it can reflect the productivity and health status of the grassland ecosystem. However, the existing grassland biomass determination samplers on the market have many shortcomings and cannot meet the actual work requirements.

[0003] Traditional grassland biomass sampling methods are mostly manual operations, requiring researchers to use simple tools such as shovels and scissors to collect samples. This method is not only extremely inefficient but also requires a lot of manpower and time. Researchers need to bend over and crouch down to operate, which can lead to physical fatigue after a long time. In addition, when sampling in a large area of grassland, the work progress is slow, and it is difficult to obtain enough samples for accurate analysis in a short time.

[0004] Some existing mechanical samplers have improved sampling efficiency to some extent, but their functions are relatively single. They can only collect a single sample and cannot collect multiple samples simultaneously. In actual biomass determination, a single sample may have a large error and cannot accurately represent the biomass situation of the entire grassland. Therefore, we have improved it and proposed a portable grassland biomass determination sampler. UTILITY MODEL CONTENT

[0005] The utility model aims at the problems existing in the background technology. In order to realize the above-mentioned utility model purpose, the utility model provides the following technical scheme: a portable grassland biomass determination sampler, comprising a sampler shell, characterized in that a servo motor is fixed on the center of the top plate of the sampler shell, and the servo motor is provided with an inner hole at the four corners of the end, which can be embedded and fixed by bolts, the power output end of the servo motor is connected with a motor shaft, the motor shaft penetrates the top plate of the sampler shell, and the bottom is connected with a rotating shaft, the rotating shaft is provided with sampling spiral blades on the outer shaft.

[0006] As a preferred technical scheme of the utility model, a sampling tube is arranged on the sampling spiral blade, and the top end of the sampling tube is installed below the center end of the sampler shell.

[0007] As a preferred technical scheme of the utility model, a sampling tube is arranged on the sampling spiral blade, and the top end of the sampling tube is installed below the center end of the sampler shell.

[0008] As the preferred technical scheme of the utility model, another end of the sampler shell is equipped with a discharge port, a flow pipeline is embedded in the bottom pipe of the discharge port, and the flow pipeline penetrates the bottom plate of the sampler shell and is connected with the discharge port.

[0009] As the preferred technical scheme of the utility model, a filter screen is arranged on the flow pipeline.

[0010] As the preferred technical scheme of the utility model, a mounting side plate is fixed to the outer surface of the middle section of the sampling tube, a buffer wheel is arranged between the two side plates of the mounting side plate, a wheel body rotating shaft is embedded in the buffer wheel, and the two sides of the wheel body rotating shaft are connected with the mounting side plate.

[0011] As the preferred technical scheme of the utility model, a determination sampling bin is arranged below the buffer wheel, and the determination sampling bin is also mounted on the mounting side plate.

[0012] As the preferred technical scheme of the utility model, a bottom plate is arranged on the outer surface of the bottom end of the sampling tube, a sample storage tank is placed on the bottom plate, and the sample storage tank corresponds to the determination sampling bin.

[0013] Compared with the prior art, the sampler has the advantages that: the overall structure is compact, the integration degree of each component is high, and the volume is small. For example, the servo motor is fixed at the center of the top plate of the sampler shell, the rotating shaft, the sampling spiral blade and other structures are reasonably arranged in the limited space, which facilitates carrying to different grassland sites for sampling work; when the servo motor drives the sampling spiral blade on the outer shaft of the rotating shaft to rotate, it can quickly drill into the grassland soil like a spiral drill, and the grassland biological and soil samples are transported upward along the spiral blade. Compared with the traditional manual sampling method, the speed and efficiency of sampling are greatly improved, and the labor and time cost is saved. By arranging multiple sample storage tanks, multiple samples can be taken, the inflowing samples can be determined for biomass, and multiple sample storage tanks taking multiple samples make the measurement result more accurate.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments.

[0023] Therefore, the following detailed description of the embodiments of the utility model is not intended to limit the scope of the claimed utility model, but only represents some embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model. It should be noted that the embodiments in the utility model and the features and technical schemes in the embodiments can be combined with each other without conflict. Similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0024] Embodiment 1: A portable grassland biomass measurement sampler, comprising a sampler shell 1, a servo motor 2 is fixed on the center of the top plate of the sampler shell 1, and the servo motor 2 is provided with an inner hole at the four corners, which can be embedded and fixed by bolts, the power output end of the servo motor 2 is connected with a motor shaft 3, the motor shaft 3 penetrates through the top plate of the sampler shell 1, and the bottom is connected with a rotating shaft 4, and the outer shaft of the rotating shaft 4 is provided with a sampling spiral blade 5. The sampling spiral blade 5 is provided with a sampling tube 6, and the top end of the sampling tube 6 is installed below the center end of the sampler shell 1. The motor shaft 3 is provided with a sample discharge driving blade 7 on the outer shaft, and the sample discharge driving blade 7 is provided with three, which are triangular, and the sample discharge driving blade 7 is located inside the sampler shell 1.

[0025] The other end of the sampler shell 1 is provided with a discharge port 8, and the bottom of the discharge port 8 is embedded with a flow pipe 9, and the flow pipe 9 penetrates the bottom plate 15 of the sampler shell 1 and is connected with the discharge port 8. The flow pipe 9 is provided with a filter screen 10. The outer surface of the middle section of the sampling tube 6 is fixed with a mounting side plate 11, and the mounting side plate 11 is provided with a buffer wheel 12 between the two side plates. The buffer wheel 12 is embedded with a wheel shaft 13 inside, and the wheel shaft 13 is connected with the mounting side plate 11 on both sides. The buffer wheel 12 is provided with a measuring sampling bin 14 below, and the measuring sampling bin 14 is also mounted on the mounting side plate 11. The bottom end of the sampling tube 6 is provided with a bottom plate 15, and the bottom plate 15 is placed with a sample storage tank 16, and the sample storage tank 16 corresponds to the measuring sampling bin 14.

[0026] The working principle of the portable grass biomass measuring sampler is as follows: start the servo motor 2, and the servo motor 2 starts to operate after being connected to the power supply. Since the four corners of the servo motor 2 are provided with inner holes, they are fixed in the center of the top plate of the sampler shell 1 by embedding bolts, which ensures the stability of the motor during operation. The power output of the servo motor 2 drives the motor shaft 3 connected thereto to rotate.

[0027] The motor shaft 3 penetrates the top plate of the sampler shell 1, and its bottom is connected with the rotating shaft 4, so the rotation of the motor shaft 3 will drive the rotating shaft 4 to rotate synchronously. The sampling spiral blade 5 arranged on the outer shaft of the rotating shaft 4 rotates with it. When the sampler is placed at the position where sampling is needed on the grassland, the rotating sampling spiral blade 5 is like a spiral drill, which continuously drills into the soil of the grassland, cutting the soil sample containing grassland organisms (such as the root system and aboveground part of grass) and conveying it upward along the spiral blade.

[0028] As the sample rises along the sampling spiral blade 5 into the sampling tube 6, the buffer wheel 12 is arranged between the two side plates of the mounting side plate 11 fixed on the outer surface of the middle section of the sampling tube 6. When the sample rises through the buffer wheel 12, the buffer wheel 12 plays a buffering role, slows down the rising speed of the sample, and avoids splashing or other problems caused by the sample rising too fast. At the same time, the buffer wheel 12 is connected with the mounting side plate 11 through the wheel shaft 13 embedded inside, and can rotate flexibly, further ensuring the stable rising of the sample.

[0029] The motor shaft 3 is provided with three sample discharge stirring blades 7 arranged in a triangular shape on the outer shaft, and the sample discharge stirring blades 7 are located inside the sampler shell 1. When the motor shaft 3 rotates, the sample discharge stirring blades 7 rotate with it. The sample rising into the sampler shell 1 will be stirred by the rotating sample discharge stirring blades 7, so as to move towards the discharge port 8.

[0030] The sample is pushed into the discharge port 8, and a flow pipe 9 is embedded in the bottom nozzle of the discharge port 8. The sample continues to flow downward through the flow pipe 9. A filter screen 10 is arranged on the flow pipe 9. During the flow of the sample, the filter screen 10 can filter the sample, filter out some larger impurities or substances that do not meet the measurement requirements, and only allow the sample that meets the requirements to pass through.

[0031] After the filtered sample flows out of the flow pipe 9, it enters the measurement sampling bin 14 installed below the installation side plate 11. The measurement sampling bin 14 can perform relevant biomass measurement operations on the flowing sample, such as measuring the weight, volume, and other parameters of the sample, to obtain relevant data of the grassland biomass.

[0032] After the measurement is completed, the sample flows out of the measurement sampling bin 14 and falls onto the sample storage tank 16 placed on the bottom plate 15 of the outer surface of the bottom end of the sampling tube 6. The sample storage tank 16 corresponds to the measurement sampling bin 14 and can accurately receive the measured sample for subsequent further analysis and research.

[0033] Example 2: Operation process of the portable grassland biomass measurement sampler: Preparation: Carefully check whether each component of the sampler is intact, including whether the sampler shell 1 has cracks or damage, whether the fixing bolts of the servo motor 2 are tightened, whether the rotating parts such as the motor shaft 3, the rotating shaft 4, and the sampling spiral blade 5 can rotate flexibly without jamming.

[0034] Check whether the discharge port 8 and the flow pipe 9 are unobstructed, and whether the filter screen 10 is clogged.

[0035] Check whether the buffer wheel 12 can rotate normally and whether the connection between the wheel body shaft 13 and the installation side plate 11 is firm.

[0036] Confirm that the measurement sampling bin 14 functions normally and can accurately perform biomass measurement related operations.

[0037] Place the sample storage tank: Place the sample storage tank 16 on the bottom plate 15 of the outer surface of the bottom end of the sampling tube 6, ensure that the sample storage tank 16 is placed stably, and its position corresponds to the measurement sampling bin 14, so that it can accurately receive the measured sample.

[0038] On-site sampling operation

[0039] 1. Select the sampling location

[0040] After arriving at the grassland site, select a representative grassland area for sampling according to the research purpose and requirements. Ensure that the grassland vegetation growth conditions and soil conditions at the sampling location are typical.

[0041] 2. Start the equipment

[0042] The sampler is placed on the selected sampling site, with the sampling auger 5 in contact with the ground. The power supply of the servo motor 2 is turned on, and the servo motor 2 is started. The servo motor 2 starts to operate, driving the motor shaft 3 to rotate, and in turn, the rotating shaft 4 and the sampling auger 5 rotate synchronously.

[0043] 3. Sampling

[0044] As the sampling auger 5 rotates, it gradually drills into the grassland soil like a auger. During the drilling process, the operator can appropriately apply downward pressure according to the actual situation to help the sampling auger 5 better cut into the soil. The soil sample containing grassland organisms (such as grass roots, aboveground parts, etc.) is transported upward along the sampling auger 5 into the sampling tube 6.

[0045] 4. Buffering and Transporting

[0046] The sample rises in the sampling tube 6, and when it passes through the buffer wheel 12, the buffer wheel 12 slows down the sample's rising speed, allowing it to rise smoothly. At the same time, the rotation of the buffer wheel 12 also helps the sample pass through this area smoothly.

[0047] 5. Sample Discharging Operation

[0048] When the motor shaft 3 rotates, the sample discharging paddle 7 installed on it also rotates. When the sample rises to the inside of the sampler housing 1, the sample discharging paddle 7 will dislodge the sample to the discharge port 8. The sample enters the flow pipe 9 from the discharge port 8, and during the flow process, the filter screen 10 on the flow pipe 9 filters the sample, removing larger impurities or substances that do not meet the measurement requirements.

[0049] Measurement and Storage Operation

[0050] 1. Sample Measurement

[0051] After the filtered sample flows out of the flow pipe 9, it enters the measurement sampling bin 14. The measurement sampling bin 14 performs relevant biomass measurement operations on the incoming sample, such as measuring the weight, volume, and other parameters of the sample, obtaining relevant data of the grassland biomass, and recording them.

[0052] 2. Sample Storage

[0053] After the measurement is completed, the sample flows out of the measurement sampling bin 14 and falls into the sample storage tank 16 below. After the sample has completely flowed into the sample storage tank 16, the servo motor 2 is turned off, and the device stops running.

[0054] Subsequent Processing

[0055] 1. Cleaning the Device

[0056] Carefully remove the sample storage tank 16 and store the sample properly. Then clean the sampler by rinsing the sample auger flight 5, sample tube 6, discharge 8, flow conduit 9, and other components with clean water to remove any residual sample and debris and keep the equipment clean.

[0057] 2. Inspection and Maintenance

[0058] Again, inspect the various components of the equipment and replace or repair any damaged or worn components. Perform any necessary maintenance on the equipment, such as adding lubrication to rotating components, to ensure that the equipment is in proper working order for the next use.

[0059] The above embodiments are only used to illustrate the technical solutions of the present application and not to limit the technical solutions described in the present application. Although the present application has been described in detail with reference to the above embodiments, the present application is not limited to the above specific embodiments, and any modification or equivalent replacement of the present application; all technical solutions and improvements which do not deviate from the spirit and scope of the present application are included in the scope of the claims of the present application.
