Description

Functional Blade Sampler

technical field

The invention relates to a sampling machine, in particular to a sampling machine suitable for sampling the veins of the functional leaves of upland cotton.

Background technique

Upland cotton is the main cultivated species in my country, accounting for more than 99%. Its functional leaves are mostly palm-shaped, with 5-lobed leaf margins and shallow notches, about 1/2 of the leaf length. There are only a few chicken feet. The characteristic is that the main leaf vein is in the shape of "wood". In the physiological and biochemical assay research of cotton, especially the content of soluble sugar, chlorophyll, proline, MDA and hormones in functional leaves at different growth stages, as well as the activities of various biochemical enzymes A large number of functional leaves were sampled, ground and extracted for determination of functional leaves when studying comparisons. In order to make the sampling representative, it is necessary to take multiple leaves from the same sample to remove the main veins, cut them into pieces of about ^1-30mm2 , mix them evenly, and then weigh the predetermined fresh weight for determination, which is a lot of work. . Due to the extremely low efficiency of manual sample cutting, the time range from sampling to completion of weighing is prolonged, resulting in increased measurement errors. Moreover, the shape and size of the manually cut blade samples are very irregular, which increases the difficulty of weighing. Coupled with the sharp increase in labor costs, sample cutting accounts for a large proportion in the determination of the content of various substances in the sample. Therefore, there is an urgent need for a sampler that is easy to operate, high in efficiency, and low in cost to replace manpower and improve the efficiency of sample cutting. Reduce experiment cost on the basis of improving measurement accuracy.

In the related research on the existing punching mechanism, Chinese patent CN102267141A discloses a punching jig, which includes a lower mold provided with a guide shaft, a die-cutting fixing plate and an upper mold sequentially connected to the guide shaft. And a spring is arranged between the upper die and the die-cutting fixing plate, and the lower die is provided with a cavity for accommodating waste materials. This patent is mainly used for removing waste after die-cutting with a punching jig. The device cannot be used for sampling on the basis of removing the main veins. Therefore, the device cannot be used for sampling the functional leaves of upland cotton.

Chinese patent CN201405391 discloses a kind of punching machine mainly consisting of base, support, punching column, upper and lower support plates, etc., and the punching machine with adjustable holes and number. The main technical problem it solves is how to realize the adjustable hole spacing, but it can only punch multiple holes with equal distances and on the same straight line at a time. Obviously, it cannot be applied to the vein removal sampling operation of cotton leaves with wood-shaped main veins. .

Chinese patent CN201669744U discloses a novel puncher, comprising a base, a support handle, and a connecting rod punch. The technical problem mainly solved by the hole puncher is how to realize the automatic reset of the punch after one stamping.

Chinese patent 202162853U discloses a multi-functional blade puncher, which includes a chassis with a central axis in the center of the chassis and circular knife rings with different apertures around it. The technical problem to be solved by the blade puncher is How to punch samples with different hole diameters, but the punch can only punch one hole at a time, and the operation of the rotating cantilever is complicated, the punching efficiency is low, and it is difficult to place and position the blades, especially the main veins cannot be removed.

Based on this, the present invention provides a sampling machine applicable to functional blades of upland cotton.

No stamping column 302 is set in the column area 301, so that it corresponds to the channel 104, that is, corresponds to the main vein of the blade, and the purpose of removing the main vein has been achieved.

In addition: in order to facilitate the operation of pressing and lifting, preferably, a handle 303 is provided on the stamping plate 300 . In order to prevent the stamping plate 300 from being disengaged from the guide rod 200 due to excessive lifting, and to facilitate the disassembly and replacement of the stamping plate, a positioning bolt 201 is screwed to the end of the guide rod 200 , and the positioning bolt 201 is located above the stamping plate 300 . In order to improve the structural compactness of the sampling machine and reduce the processing cost, the bottom plate 100, the support plate 101 and the fixing plate 102 are integrally formed, preferably by sheet metal design.

Embodiment two

This embodiment is a further improvement on the basis of the first embodiment, and the technical solution of the first embodiment also belongs to this embodiment, and will not be described repeatedly in this embodiment.

Specifically, as shown in FIG. 4 , the sampling machine further includes a pre-compression plate 400 slidably mounted on the plurality of guide rods 200 and a stud 500 affixed to the pre-compression plate 400 .

The pre-pressing plate 400 is located between the stamping plate 300 and the bottom plate 100, and the stud 500 can slide through the stamping plate 300, and the end of the stud 500 is screwed with an adjusting bolt 501, and the adjusting bolt 501 is located at the The top of the stamping plate 300 is used to prevent the pre-pressing plate 400 from moving downward excessively and cause the stud 500 to break away from the stamping plate 300; a compression spring 502 is also set on the stud 500, and the compression spring is located between the stamping plate 300 and the pre-pressing plate 400 In between, it is used to realize the automatic reset of the stamping plate 300 after the stamping action is completed, and to prevent the stamping plate 300 from directly touching the pre-pressing plate 400, which will cause instantaneous large pressure between the pre-pressing plate 400 and the blade to damage the blade, and , in order to be suitable for blades of different thicknesses, the distance between the punching plate 300 and the pre-pressing plate 400 can be adjusted by adjusting the upper adjusting bolt 501, and then the compression degree of the pressure spring can be adjusted to adjust the extrusion between the pre-pressing plate 400 and the bottom plate 100 degree purpose. The pre-pressing plate 400 is provided with a non-through-hole area 401 corresponding to the no-punching column area 301 and a plurality of through holes 402 one-to-one corresponding to the stamping column 302 for the stamping column 302 to pass through. Wherein the pre-pressing plate 400 contacts the blade before stamping the blade, and is used to position the blade to prevent the main vein from being dislocated during punching. In order to be able to immediately monitor whether the main vein of the blade fits in the channel 104, The pre-pressing plate 400 is made of transparent material.

The shapes of the pre-pressing plate 400 and the stamping plate 300 are preferably set to be equivalent to the shape of the bottom plate, that is, respectively set as rectangles, so as to improve the structural compactness of the sampling machine.
