Description

Self-sealing sampling drill rod for bean sampling inspection

Technical Field

The utility model relates to a from stifled sample borer of sealing for beans selective examination belongs to food detection sampling device technical field.

Background

Beans are one of the most important crop and food raw materials at present, and become one of the most widely planted agricultural products with the largest yield due to rich protein and grease content. Beans represented by soybeans (soybeans), black beans, red beans, and the like have a remarkable feature that the shape is circular or quasi-circular. The quality of beans needs to be checked after harvesting, as food or feed, even as raw material for oil extraction, before production. Prior to testing, the legume material packed in the sack is randomly sampled.

At present, a tubular sharp instrument, namely a sampling drill rod, is mainly adopted for the spot check before the detection of bean products. The existing sampling drill rod is generally provided with a sharp pointed end so as to be conveniently and smoothly penetrated into a gunny bag; the rear side of the tip is a cylindrical drill body, and a sampling hole for collecting beans is arranged on the drill body. During sampling, the inspector randomly punctures the gunny bag by using the sampling drill rod to draw the bean sample. Although convenient and fast, the sampling method still has some problems. For example, the sampling drill damages the gunny bag, and beans flow out along the punctured holes. Although beans can block the hole due to the extrusion of volume problem, the vibration in the transportation or handling process can change the stress balance under the original standing extrusion state, can continue to cause the leakage of beans. Meanwhile, beans such as soybeans are nearly spherical, so that the rolling effect is very good, and once the beans are scattered on the ground, passers-by are careless and easily fall into the ground.

On the other hand, the conventional sampling drill usually adopts an open sampling hole, and the obtained bean sample is easy to spill from the open sampling hole due to misoperation after sampling.

The present invention will be described in further detail with reference to the accompanying drawings, but the present invention is not limited by the following detailed description.

Fig. 1 is a schematic perspective view of a sampling drill tip according to a preferred embodiment of the present invention. As can be seen from fig. 1, the tip 1 is composed of a connecting ring 11 provided with an internal thread 111 and a cone 12 with missing side portions. Wherein the cylindrical body 12 forms a truncated cone-shaped receiving cavity I13 with its sides opened by the gap.

Fig. 2 is a schematic perspective view of a sampling drill rod outer sleeve according to a preferred embodiment of the present invention. As shown in fig. 2, the outer sleeve 2 has a hollow cylindrical body, two ends of which are open, and an external thread 21 is provided on an outer circumferential surface of one end of the outer sleeve to be engaged with the internal thread 111. Meanwhile, two strip-shaped sampling holes 22 are axially formed in the circumferential side surface of the sampling drill rod, so that after the sampling drill rod is inserted into the sack, a sample enters the sampling drill rod from the sampling holes 22.

Fig. 3 is a schematic perspective view of an inner tube of a sampling drill rod in a preferred embodiment of the present invention. As can be seen from fig. 3, the inner tube 3 includes an inner tube head 31 having no sharp tip, an inner tube core 32 connected to the inner tube head 31, and a grip portion 33 connected to the inner tube core 32. The structure of the inner tube head 31 is similar to the tip 1 shown in fig. 1, except that the bottom of the conical surface is provided with a sealing surface which is communicated with the air duct 322 of the inner tube core 32 only through the air inlet hole 313. An air duct 322 for communicating the inner tube head part 31 and the handle part 33 is arranged on the hollow inner side wall of the inner tube core 32. At the same time, axially distributed notches 323 are provided on the circumferential side of the inner core 32, the area of the notches 323 being larger than the area of the two sampling holes 22, so as to avoid a reduction in the feeding cross-sectional area of the sampling holes 22. Meanwhile, the grip part 33 located at the rear of the inner tube 3 is a cylinder having an increased diameter. The front end of the handle part 33 is provided with an inward-recessed slot 334 so as to facilitate the insertion of the inner tube 3 with the outer sleeve 2. Meanwhile, the inside of the handle portion 33 at the rear of the insertion groove 334 is a cavity, and the cavity is sealed by a flexible and compressible material to form the squeezing bag 333. The squeeze bag 333 communicates with the head of the inner tube via the airway tube 322. Meanwhile, in order to ensure the gas supplement, an openable and closable vent hole is formed on the shift knob 332 in the front of the handle part 33, and the vent hole is communicated with the cavity. The shift knob 332 protrudes from the circumferential surface of the grip portion 33 to function as a position index.

Fig. 4 is a schematic perspective view of the inner tube head of the sampling drill in a preferred embodiment of the present invention. As can be seen from fig. 4, the receiving chamber II311 of the inner tube head is divided into two large and small parts by the push-up bag 312. Wherein a large portion is used to accommodate the air bladder in a compressed state, and a small portion is communicated with the squeeze bladder 333 at the rear side of the handle portion 33 through the air inlet hole 313 and the air guide tube 322.

Fig. 5 is a schematic top view of a sampling pin assembly according to a preferred embodiment of the present invention (during sampling). Fig. 6 is a schematic perspective view of fig. 5. Fig. 7 is a schematic perspective view of the assembly after the inner tube of fig. 5 is rotated 90 degrees counterclockwise. As can be seen from FIGS. 5 to 7, in the sampling probe, the notch of the inner core 32 of the inner tube 3 overlaps with the sampling hole 22 of the outer tube 2 at the start of sampling, thereby forming a passage for allowing the sample to enter the inner core 32. Meanwhile, at the tip 1, the gap of the tip 1 and the gap of the inner tube head 32 do not overlap, so that the two are complementary to form a sealed cavity. At this time, the air bag in a compressed state is installed in the sealed cavity. When sampling, the operator can puncture the sampling drill into the gunny bag under the state. After sampling, the gear knob 332 is turned to rotate the inner tube 3 and the outer sleeve 2, so that the circumferential side surface of the inner tube core 32 is rotated to block the sampling hole 22 to finish the sample entering. At the same time, the notch of the tip 1 and the notch of the inner tube head 31 overlap with each other by rotation, and the airbag is in a disengaged state. When the sampling drill is about to pull out the sack, the pressing bag 333 is pressed to promote the push-up bag 312 to be expanded, thereby realizing the ejection release of the air bag into the sack. The diameter of the air bag is actually larger than the diameter of the outer sleeve 2, namely the diameter of the opening of the gunny bag, in a compressed state, so that self-plugging is realized. When the sampling drill rod is pulled out, the space occupied by the sampling drill rod originally in the jute bag is short of fillers, and the air bag can smoothly enter the space by means of instant air pressure constant force to realize plugging. Meanwhile, the size of the air bag is obviously larger than that of the bean sample, so that the separation is convenient to identify. This kind of sampling borer can effectively realize the self-sealing of sample process, prevents that the beans sample from unrestrained extravagantly to and cause personnel consequently fall injured.

Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention.
