Background
The threshing machine is an important device for threshing and redrying in the tobacco industry and is divided into two parts, namely threshing and sorting. The threshing is to separate the tobacco leaves from the tobacco stems by using a machine, and the sorting is to sort the torn tobacco leaves from the mixed materials by using wind energy and blow the tobacco leaves to a mesh belt; the tobacco leaves with lighter weight are blown up by wind and sent to a gathering belt, and the materials which do not completely realize stem and leaf separation are sent to the next leaf collecting and threshing wind separation bin by a net belt because of heavier weight, and the threshing and sorting treatment is continued.
In the threshing and air separating process, not only is the tobacco leaf breakage caused by overlarge wind speed reduced, but also the stem and leaf separation failure caused by too small wind speed is avoided. Therefore, before working, the wind power of each wind sub-bin needs to be detected and debugged to ensure that the wind sub-bins can be in the optimal wind power sorting state, so that the wind sub-quality is improved.
At present, the wind field of each wind sub-bin is usually detected by adopting a manual method: detecting personnel enter the wind separation bin, a bin door is closed, nine positions above the mesh belt are measured one by using a wind speed measuring instrument, data are recorded, and an operator outside the bin adjusts a corresponding wind speed switch according to the detected data; the above steps are repeated for a plurality of times until the wind speeds of nine positions of each wind sub-bin meet the requirements. Obviously, the manual detection of the wind speed not only has high labor intensity and low efficiency, but also has great harm to the health of detection personnel by a wind field; improvements are needed.
Disclosure of Invention
In order to overcome the above-mentioned defect that exists among the prior art, the utility model aims at providing a thresher wind divides storehouse wind speed detection device to replace the manual work to carry out automated inspection to each wind branch storehouse wind field.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the wind speed measuring device comprises a plurality of wind speed measuring sensors which are fixed on a measuring frame and electrically connected with a computer; the measuring frame consists of two longitudinal guide rods which are arranged in parallel and three transverse guide rods which are arranged between the two longitudinal guide rods in parallel and are respectively arranged on the two longitudinal guide rods through longitudinal sliding sleeves; three movable brackets are arranged on each transverse guide rod, and a wind speed sensor is fixed on each bracket; the support is composed of a transverse sliding sleeve arranged on a transverse guide rod, a mounting pipe fixed on the transverse sliding sleeve, a fine adjustment rod arranged in the mounting pipe and a mounting plate fixed on the fine adjustment rod, and the wind speed sensor is fixed on the mounting plate.
Locking screws are arranged on each longitudinal sliding sleeve, each transverse sliding sleeve and each mounting pipe; each longitudinal guide rod is provided with two lifting adjusting frames, and each lifting adjusting frame consists of a sleeve arranged on the longitudinal guide rod, an adjusting sleeve vertically crossed and fixedly connected with the sleeve, a lifting rod positioned in the adjusting sleeve and a limiting screw fixed on the adjusting sleeve.
Compared with the prior art, the utility model discloses owing to adopted above-mentioned technical scheme, lay the net area in the wind branch storehouse with the measuring rack that is fixed with nine air velocity transducer, consequently the measurement personnel need not get into the wind branch storehouse and can pass through nine measuring position's of computer audio-visual display wind speed, master the wind field condition to can adjust each corresponding wind speed control switch in view of the above, reach required requirement until the wind field. By adopting the utility model to replace personnel to enter the wind field for detection, not only the efficiency is effectively improved and the labor intensity is reduced, but also the damage to human body caused by wind field noise and the like can be thoroughly avoided; the device has the advantages of simple structure, convenience in operation, high detection efficiency and the like. In addition, because the utility model discloses each component has all adopted the bushing structure, consequently can assemble temporarily or dismantle according to actual need, accomodate also very conveniently.
