Because there may be a serious accumulation condition, the air pressure sprayed out is relatively large at this time, so a baffle is arranged at the far end, and the light material is prevented from being blown out of the high-speed belt.

Compared with the prior art, the utility model has the beneficial effects that:

(1) The uniform auxiliary material device solves the problem that the material at the outlet of the cross gate is accumulated to one side, and therefore the influence on tobacco leaf winnowing effect caused by throwing of the non-uniform material to the flat winnowing pipeline is avoided.

(2) The air is provided by original equipment, equipment such as an air compressor is not required to be additionally arranged, and the structure is simple and the practicability is high.

(3) The sprayed air pressure can be adjusted in an adjustable range according to actual conditions, and the applicability is good.

(4) The baffle is arranged, so that part of light materials (such as tobacco leaves or light tobacco stems) can be effectively prevented from being blown out of the high-speed belt.

Detailed Description

The utility model will be described in further detail below with reference to the drawings by means of specific embodiments.

Example 1

As shown in fig. 1-3, the embodiment provides a high-speed belt uniform spreading device for threshing a drop in a long stem, comprising: the blowing assembly 2 and the baffle 3, wherein, the blowing assembly is located on the left wallboard 11 of cross door 1 exit, and is located the material and piles up one side for will blow off and pile up the material, and the baffle 3 is located on the right wallboard 12 of cross door 1 exit, is used for stopping some light material (such as tobacco leaf or light tobacco stalk) to be blown off high-speed belt 5. Preferably, the baffle 3 is 90cm×40CM in size and is made of aluminum alloy. The material falls from the exit of cross door 1, blows the back with piled up material under the effect of jetting subassembly 2, and is again relatively even fall on high-speed belt 5, send flat selection by winnowing pipeline by high-speed belt 5 to solve and pile up because of tobacco stalk one side and cause follow-up selection by winnowing effect poor and leaf rate high quality scheduling problem in the stalk.

Specifically, as shown in fig. 4-7, the jetting assembly 2 includes: the end of the nozzle 21 is provided with threads, and the nozzle 21 passes through the right wall plate 12 and is fixed on the right wall plate 12 through bolts. The vertical distance between the nozzle 21 and the high speed belt 5 is 20CM to leave space for the material to fall down, ensuring that the light piled material has sufficient time to disperse to other positions. One end of the air supply pipeline 22 is connected with the nozzle 21, and the other end is connected with the interface of the main air pipeline 6 of the threshing device through a three-way pipe, so that the original functions of the interface of the original main air pipeline 6 are reserved while the original air supply is utilized. The gas sprayed out of the nozzle 21 is provided by the original threshing equipment, so that equipment investment is reduced, and the function of uniformly spraying and blowing the accumulated materials can be realized.

Preferably, the air supply pipeline 22 is laid along the threshing equipment frame 4 and is fixed by an air pipe bracket 25, so that the air supply pipeline 22 is tidied, and the field cleanliness is improved. The air supply line 22 is provided with a valve 23 for opening/shutting off the air supply and a pressure gauge 24 near the main air line 6. In the actual use process, the opening of the valve 23 can be adjusted according to the actual situation, and the current air supply pressure is intuitively fed back by the pressure gauge 24, so that the refining effect is ensured. Preferably, the pressure of the blowing gas is 0.06MPa-0.1MPa, so that not only is the phenomenon that the accumulated materials are all blown to other areas due to overlarge pressure avoided, but also the phenomenon that the refining effect cannot be achieved due to overlarge pressure can be prevented.

In this example, the air pressure was 0.08MPa. When the device is not put into use, sampling the leaf content in the stems of the tobacco stems after winnowing, wherein the leaf content in the stems is 4.08%. After the device is put into use, the leaf content in the stems is 1.23%, so that the uniform spreading device can be used for carrying out refining treatment on the materials on the stacking side of the cross gate 1, so that the problem of material stacking when the outlet of the cross gate 1 falls is avoided, the leaf content in the stems is effectively reduced, and the production quality is ensured.
