Description

Technical field:

[0001] The invention relates to a mechanical manufacturing technology, a walking straw burning vehicle which is a special vehicle for burning straw in the field and can walk horizontally and vertically. This invention solves the straw burning problem that farmers have been unable to deal with for many years and is a new technology that is fast, safe, environmentally friendly and energy-saving. Technical background:

[0002] The technology of straw burning vehicle comes from ordinary machinery manufacturing and solid fuel hot air furnace combustion technology such as: air distribution technology, dust removal manufacturing technology, insulation technology, and the driving technology comes from electric drive. The traditional hot air furnace technology is a fixed equipment, and the burning vehicle needs to burn the messy straw on the ground in a mobile state. This is a completely different technology. It is necessary to manufacture a suitable frame that can walk and solve the problem of combustion chamber sealing and hot air combustion. The high-temperature resistant insulation material of the combustion chamber is selected from aluminum silicate insulation cotton. This material is light in weight and has strong high-temperature resistance. The straw burning vehicle needs to be equipped with a generator set and a liquefied gas ignition system, and the hot air preheating serpentine pipe is made and installed for the flue gas inlet and outlet pipes. The driving technology requires 4 wheels with 300 rotation directions to control the longitudinal and lateral walking of the burning vehicle. The above technologies do not have matching applicable products and require new development of required components. Summary of the invention:

[0003] In response to the above: the present invention is a walking straw burning vehicle, the purpose of which is to solve the problem that straw and pests in the field are rotting and cannot be burned directly. The burning vehicle can burn the straw in a fixed area safely and effectively in an environmentally friendly way. This is a good invention that benefits the country and the people. The burning vehicle must be sturdy and durable, low in cost and low in operating cost. Because there are no similar products at home and abroad for this invention, the future market prospects are broad and there is much to be done.

[0004] The present invention is achieved in that:

[0005] 1 The incinerator first needs to make a solid frame. The material is 160mm*160mm6mm square tubes welded into a large steel structure frame with a length of 8 meters, a width of 3 meters, and a height of 2.33 meters ( Figure 1 Part No. 6) All the auxiliary support reinforcement plates of the main steel frame must be fully welded. The combustion chamber is designed to be 380mm above the bottom frame of the incinerator plus the height of the tire bracket. The top of the combustion chamber is 800mm above the ground. Figure 4 Part No. 17), the frame is made of 12# channel steel for main beam, auxiliary support, 65*65*6mm angle steel, the spacing shall not be greater than 500mm, and finally a layer of 6mm steel plate is laid with all beams intermittently welded plates and plates are fully welded, and a smoke guide groove is reserved on the bottom plate for connection ( Figure 4 Part No. 23).

[0006] 2. The incinerator is moving horizontally during sealing operation. The front and rear seals are sealed with steel drums. The drum size is ( Figure 1Part No. 9-1) The rollers designed in this way can effectively prevent air leakage on uneven ground. Blade-type steel strips are used on both sides of the incinerator ( Figure 4 Part No. 28-1) The polygonal sealing hanging plate can be overlapped with the terrain to effectively seal, and it can also effectively separate the straw inside and outside the vehicle from sticking to prevent the fire from igniting the straw outside the vehicle. When the incinerator is not in operation, all sealing hanging parts can be retracted 500mm upwards through the electric pull rod for easy walking ( Figure 1 Part No. 1), and two electric straw cutters are installed at both ends of the vehicle to effectively separate the straw when encountering some large or large straw and burn it in the vehicle ( Figure 1 Part No. 8).

[0007] 3. The internal combustion chamber needs to solve the problem of high temperature insulation. Weld a heat-insulating nail on the top shell steel plate of the combustion chamber, hang aluminum silicate wool, cover it with a layer of wire mesh, buckle the heat-insulating nail, and apply heat-resistant cement material ( Figure 3 Part No. 17) Aluminum silicate insulation layer has the advantages of heat resistance, heat insulation and light weight, and is an ideal material.

[0008] 4. Two high-pressure blowers are installed in the hot air preheating system ( Figure 2 Part No. 13) The 2 kW high pressure blower with worm gear sends cold air into the serpentine preheating main pipeline through the air outlet ( Figure 3 Part No. 20) 50 diameter seam steel pipe passes through the serpentine pipe for heating and enters the outlet main pipe ( Figure 3 Part No. 19) has a diameter of 50 and a seam length of 7.5 meters, which is then distributed from the outlet main pipe to multiple rows of combustion nozzle main pipes ( Figure 3 Part No. 21) 50mm diameter seam pipe length 8.2m total 6 rows of nozzles pipe spacing 300mm install one nozzle ( Figure 3 Part No. 22) 15mm diameter tube, the nozzle is about 200mm above the ground, and the height of the nozzle from the ground can be adjusted by the rotation angle of the nozzle main pipe ( Figure 4 Part No. 29) Hot air main pipe joint ( Figure 4 Part No. 31) Main pipe connecting pipe elbow, ( Figure 4 Part No. 26) Main pipe steering connecting rod ( Figure 4 Key No. 27) Main pipe angle adjustment handle.

[0009] 5. The combustion chamber ignition system comes with 2 liquefied gas cylinders ( Figure 2 Part No. 12) is controlled by a solenoid valve on a liquefied gas main pipe. The liquefied gas nozzles are electronically ignited. The ignition nozzles in the combustion chamber are installed on the main pipe at intervals of 300 mm. Figure 3Part No. 24) The nozzle is 300mm long and 10mm in diameter. Light the straw and burn it for a few minutes. After the temperature in the combustion chamber rises, turn off the liquefier ignition device and start the hot air. The nozzle is generally about 200mm above the ground and can be adjusted in height by the total rotation angle of the nozzle. The diameter of the liquefied gas ignition main pipe is 25mm. Both ends extend out of the combustion vehicle shell. A controllable rotating handle is installed on one end of the pipe to adjust the angle. When not in operation, the nozzle can be rotated and put away to avoid scratching.

[0010] 6 The smoke exhaust and dust removal system is to make two smoke guide grooves in the front of the combustion chamber ( Figure 3 Part No. 23) The guide groove is welded with 6mm steel plate into two sizes of 3840mm*400mm*400mm and then passes through the flue outlet pipe ( Figure 1 Part No. 4) Steel pipe with a diameter of 200 mm enters the multi-tube bag filter ( Figure 1 Part No. 5) Bag filter Length 2800* Width 1300* Height 1860 Welded with 6mm steel plate Two openable covers are designed on the top for easy installation and maintenance of bags, internal bag height 1000mm Quantity 144 bags ( Figure 3 Part No. 18) by the induced draft fan ( Figure 2 Part No. 11) Worm gear 5 kW induced draft fan, dust collector connecting duct ( Figure 1 Part No. 3) Steel pipe with a diameter of 200mm is discharged through the chimney, and the chimney has a diameter of 300mm ( Figure 1 Part No. 2), the outside of the dust collector and pipeline must be wrapped with heat insulation cotton and then a layer of iron sheet.

[0011] 7 The walking system is installed at both ends of the incinerator and can be driven by electricity to drive the worm gear reducer ( Figure 1 Part No. 7) Worm gear connecting rod ( Figure 4 Part No. 30) drives the wheels to turn 300 degrees to control the direction of travel ( Figure 2 Part No. 15-16) Steering gear unit bearing bracket hub motor (attached Figure 1 Item 10) The tire diameter is 900mm, and the four wheels are driven by independent motors. The off-road solid tires are equipped with hydraulic brakes. The maximum speed of the vehicle is designed to be within 20 kilometers per hour.

[0012] 8 In order to facilitate the two walking modes, a sliding cab is designed ( Figure 4 Part No. 25) The cab can be slid out to improve the lateral driving line of sight. The cab slides on two cylindrical slide rails and an electric screw pushes the cab to slide on the track. All equipment controls on the incinerator are in the cab. The vehicle is also equipped with a safety fire water tank and a high-pressure water pump for use in emergency situations.

[0013] 9 The incinerator power comes from a 25 kW generator set ( Figure 2 Part No. 14) The incinerator is equipped with lighting facilities and lead-acid batteries. Description of the drawings:
