Description

Special multifunctional sampler for grain depot

technical field

The utility model relates to the technical field of granary sampling or dust collection, in particular to a special multifunctional sampler for granary.

Background technique

At present, the method for sampling granaries is relatively backward, and the traditional manual spinning sampling method is still used. This method requires a lot of physical effort, and the sampling depth is limited. The closer to the bottom of the granary, the more difficult it is to sample. The method of screwing and pressing down may also cause cheap sampling and damage the anti-corrosion layer on the grain epidermis and the surface of the sampling barrel. The sampling efficiency of this method is very low. In addition, in terms of granary management, it is usually necessary to send cables carrying temperature and humidity sensors to different positions in the granary. The traditional method is to clamp the cable at one end of the straight sampling pipe and then forcefully spin the straight sampling pipe to make the cable go deep into the granary. Specifying the position is time-consuming and labor-intensive, and there is still the defect of insufficient depth. More importantly, one end of the cable is forcibly inserted into the bottom of the granary, which is easy to cause damage to the cable or sensor, and the work efficiency is very low.

Utility model content

The utility model overcomes the deficiencies in the prior art and designs a special multifunctional cutting sampler for grain depots.

Technical solution: A special multifunctional sampler for grain depots, including a sampling barrel, a bracket, and an upper cover that is matched and installed on the upper end of the sampling barrel. An exhaust fan is installed in the upper cover, and the air inlet of the exhaust fan is located on the upper cover. The lower surface of the exhaust fan is located on the upper side of the loam cake, the side wall of the sampling barrel is provided with an air extraction port, and an air extraction pipe and an air intake pipe are respectively installed on the air outlet and the air extraction port, and The other end of the intake pipe is matched with a straight sampling pipe.

The ring matching set has a filter bag inside the sampling bucket.

It also includes at least one sampling extension pipe matched with the sampling straight pipe.

A controllable wire winding mechanism is also arranged in the inner chamber of the upper cover housing and a control switch is provided outside the upper cover housing.

An elastic clamping mechanism and a control button are respectively provided at the installation ports of the air intake pipe and the air extraction pipe.

The intake pipe is also provided with a switch to control the strength of the intake air.

An arc-shaped stop is also provided on the inner upper edge of the air suction port.

A floor brush, or a water-absorbing floor brush, or a triangular brush, or a flat tube, or an air suction tube is also matched at the end of the sampling straight pipe or the sampling extension pipe.

The beneficial effects of the utility model:

1. The special multi-functional sampler for grain depots of the present utility model is very easy to operate, so that sampling is very easy. When sampling, it does not need to rotate or press down forcefully. The principle of sampling is to sample the grain in the straight pipe. Hollows appear around the lower end of the straight pipe to drive the sampling straight pipe further deeper into the bottom of the granary. It has the advantages of strong suction, fast sampling speed, reduced labor intensity, accurate positioning, large sampling depth, reliable use, and easy operation. Since the traditional spinning operation is fundamentally overcome, it will not cause damage to the anti-corrosion layer of the sampling barrel or the grain, ensuring the original quality of the raw grain. The utility model can be made of stainless steel, and the scattered grains (wheat, corn, sorghum, rice, etc.) of the opposite silo, room type warehouse and underground warehouse can be randomly sampled within the range of 0-30 meters.

2. The special multi-functional sampler for grain depots of this utility model can also assist in burying measuring cables into the grain warehouses. The operation is very simple, and only one end of the cables needs to be placed in the slot at the end of the straight sampling pipe or the sampling extension pipe. That is, it can be positioned quickly and accurately without causing damage to cables and sensors. At the same time, relying on this method, it is also possible to dispense medicine to any position in the granary.

3. The multi-functional sampler for grain depots of the present utility model can also be used as a vacuum tool for wet and dry vacuuming and sampling, for example, wearing a floor brush, or a water-absorbing floor brush, or a triangular brush, or a flat brush. Tools such as pipes, or suction pipes have the characteristics of convenience, practicality and multi-function. The utility model has the advantages of simple structure, reasonable design, easy processing and manufacturing, and is very beneficial to popularization and implementation.
