Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to a sampling equipment for seed sales. Background Art

[0002] The sampling device for seed sales is a sampler, the tip of which can be inserted into a container, so that the seeds in the container slide into the through groove and enter the sampler, and then slowly pulled out, thereby completing the sampling inspection of the seeds in the container.

[0003] However, when using the sampler, since the samples used for the random inspection need to meet the requirements of randomness, and when the sampler is inserted into the container, a certain amount of seed samples will enter the sampler, making it impossible to obtain the seed samples in the middle of the container. In order to maintain the accuracy of the random inspection results, it is necessary to re-sample different positions in the container. When continuing to use the sampler for sampling, the original seed sample in the sampler needs to be taken out first. The taken out seed sample is easy to be mixed with seeds from other positions if not properly stored, resulting in the staff being unable to distinguish the source of the seed sample, which in turn hinders the inspection work and is not conducive to the inspection personnel to conduct sampling inspection on the batch of seeds.

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] Example 1

[0024] The existing sampler is to insert the tip of the sampler into the container to be sampled and tested. After manually shaking it for several times, the seeds will enter the sampler under the action of gravity. At this time, the sampler is gently taken out, and the sampler and the seed sample are taken out. When it is necessary to sample samples at different positions in the container, the worker needs to use multiple samplers or take out the sample in the sampler before sampling, which will increase the workload of the worker for spot checking seed samples. In addition, the seed sample first taken out from the sampler is easy to mix with the seed sample of other parts, resulting in unclear distinction. This embodiment provides a sampling device for seed sales, such as Figure 1-Figure 2 As shown, it includes a sampler body 1 and a tip 2 arranged at the front end of the sampler body 1. A sampling mechanism 3 for stratified and uniform sampling is arranged in the sampler body 1. When workers conduct random inspections of seed samples, they insert the sampler body 1 together with its tip 2 into a container containing seed samples. When the sampler body 1 reaches a certain position in the container, the worker operates to rotate the sampling mechanism 3, so that the sampler body 1 can store seed samples at different positions in the same container at the same time, which is beneficial for the inspectors to obtain accurate inspection results for the batch of seeds.

[0025] The sampling mechanism 3 includes a through slot 31 provided on the surface of the sampler body 1. The seed sample in the container can enter the sampler body 1 through the through slot 31 under the action of gravity. An arc slot 32 is provided on one side of the through slot 31, so that the arc plate 34 can slide in the arc slot 32, thereby controlling the opening or closing of the through slot 31. A flexible spring 33 is provided in the arc slot 32. When the arc plate 34 moves, the through slot 31 gradually opens. At this time, the arc plate 34 gradually squeezes the spring 33 and generates a reaction force on the arc plate 34. One end of the spring 33 is provided with an arc plate 34 sliding in the arc groove 32, which can separate the seed sample from the sampler body 1 in the initial state. During the movement, the seed sample gradually enters the through groove 31. A sliding member 35 for controlling the arc plate 34 to slide in the arc groove 32 is provided in the arc groove 32. The rotating rod 36 can be manually controlled to rotate, so that the sliding member 35 works to pull the arc plate 34 to move in the arc groove 32, and the sampling work starts. The rotating rod 36 is connected to the rotating rod 36 in the sampler body 1. , can be rotated manually in the sampler body 1, and the surface of the rotating rod 36 is provided with a plurality of blocking plates 37, which can divide the sampler body 1 into a plurality of independent spaces that do not interfere with each other. When the worker is sampling the seed sample, he first inserts the sampler body 1 into a certain position in the container, and then rotates the rotating rod 36, so that the rotating rod 36 drives the blocking plate 37 to rotate 90 degrees, and the rotating rod 36 will push the arc plate 34 to move in the arc groove 32, so that the through groove 31 is gradually opened, and the arc plate 34 squeezes Spring 33, the seed sample slowly enters the sampler body 1, when the rotating rod 36 rotates 90°, the blocking plate 37 is separated from the arc plate 34, and the arc plate 34 returns to the initial position in the arc groove 32 under the action of the spring 33, thereby closing the through groove 31, and ending the sampling of the seed sample at this position in the container. When the sampler body 1 is pulled out and inserted into another position, the above operation is repeated, thereby achieving the purpose of stratified extraction of samples at different positions in the same container, which is conducive to enhancing the accuracy of sample data.

[0026] The blocking plate 37 is arc-shaped, and a sampling interval 38 is set between adjacent blocking plates 37, so that when the seed sample enters the sampling interval 38 through the through groove 31, the seed sample moves to the bottom of the sampling interval 38 under the action of gravity, thereby preventing the seed sample from falling when the sampler body 1 is taken out.

[0027] After the worker manually inserts the sampler body 1 into a certain position in the container, he rotates the rotating rod 36 to open the through slot 31, so that the seed sample at this position enters the sampling interval 38, so that the seed sample at this time is random, which is conducive to the accuracy of the detection result. The sliding member 35 includes a push rod 351 arranged at one end of the arc plate 34 and in contact with the blocking plate 37, and a trapezoidal block 352 is provided on the side of the arc plate 34 away from the push rod 351, and a group of positioning blocks 353 sliding in the arc groove 32 are provided at one end of the arc plate 34, and a trapezoidal groove 354 for the trapezoidal block 352 to slide into is provided in the through slot 31. When the worker starts to extract the seed sample, he will first rotate the rotating rod 36, so that the blocking plate 37 on the surface of the rotating rod 36 pushes the push rod 351 to move, and the push rod 351 drives the arc plate 34 to move. The arc plate 34 slides in the arc groove 32, and because the arc plate 34 is smaller than the size of the arc groove 32, when the arc plate 34 moves in the arc groove 32, the positioning block 353 at one end thereof and the trapezoidal block 352 slide along the surface of the arc groove 32, so that the arc plate 34 performs a quasi-circular motion in the arc groove 32, and when the trapezoidal block 352 moves to the trapezoidal groove 354, due to the elastic force of the spring 33 on the arc plate 34 and the thrust of the arc plate 34 on the push rod 351 and the arc plate 34, a balance is reached between the two, and when the trapezoidal block 352 moves to the trapezoidal groove 354, due to the change in the force point of the arc plate 34, the arc plate 34 tilts in the arc groove 32, so that the push rod 351 is separated from the blocking plate 37, and at this time, the arc plate 34 returns to its initial position in the trapezoidal groove 354 under the action of only the elastic force.

[0028] A marking point 1 39 corresponding to the position of the sampling room is provided on the side of the sampler body 1 away from the tip 2, and a knob 310 for manually rotating the rotating rod 36 is provided at one end of the rotating rod 36, and a marking point 2 311 corresponding to the marking point 1 39 is provided on the surface of the knob 310. Since the sampler body 1 is made of opaque stainless steel, the operator cannot directly see the position of the rotating sampling room in the sampler body 1. When the marking point 1 39 and the marking point 2 311 are in a straight line, it means that there is a sampling interval 38 in the positive position of the through slot 31. When the rotating rod 36 rotates 90° every time, the positive position of the through slot 31 will be replaced by the next sampling interval 38.

[0029] Example 2

[0030] When the sampling interval 38 in the sampler is completely filled with seed samples, the staff needs to manually open the through slot 31 and rotate the rotating rod 36 to pour out the seed samples in the sampling interval 38 through the through slot 31 when finishing the sampling work and taking out the seed samples from the sampler body 1. However, this pouring method is relatively slow. Figure 3As shown, a groove 312 is provided in the knob 310, and a protrusion 313 that fits with the groove 312 is provided on the surface of the rotating rod 36. When the worker takes out the seed sample in the sampler body 1, the rotation is separated from the rotating rod 36, thereby directly pouring out the seed sample in the sampler body 1, or the groove 312 on the knob 310 and the protrusion 313 on the surface of the rotating rod 36 are fitted with each other, so that the knob 310 is fixed on the rotating rod 36, which is convenient for the worker to rotate the knob 310, thereby driving the sampling interval 38 to rotate in the sampler body 1 for sampling.
