Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a flame weeding device integrated with remote-controlled electronic ignition. Background Art

[0002] Flame weeding technology, as a physical weed control method, has been gradually promoted and applied in the agricultural field in recent years. This technology heats the weeds through the high-temperature flame released by the flame nozzle, causing protein denaturation and cell membrane rupture, and eventually withering and dying, thereby achieving the effect of prevention and control. It has the characteristics of no pesticide residues, long duration, and environmental friendliness, and can effectively avoid the pollution of the environment and soil caused by chemical herbicides.

[0003] However, in China, the application scope of flame weeding technology is greatly limited. Current flame weeding equipment is mainly divided into two types: large mechanical type and simple handheld type. In the use of existing equipment, in most cases, operators need to rely on external lighters to manually ignite at close range. This operation method is not only cumbersome and time-consuming, but also poses a safety hazard.

[0004] In addition, the flame nozzles of most flame weeding equipment are currently exposed to the environment, and are significantly affected by external environmental conditions (such as wind, temperature and humidity). Among them, the impact of strong winds on flame weeding equipment is mainly manifested in two aspects: first, at the flame nozzle, the gas spreads rapidly due to the action of wind, resulting in a decrease in concentration, and the flame produced by the manual igniter is easily blown out, which increases the difficulty of ignition and reduces the operating efficiency; second, the high-temperature flame released by the exposed flame nozzle lacks protection and is prone to deviation under the influence of strong winds, which will reduce the targeting of the flame and cause damage to crops. At the same time, there is a potential risk of flame spread. In addition to wind, environmental factors such as humidity and temperature will also affect the ignition efficiency. In high humidity or low temperature environments, the ignition time of traditional manual igniters will be prolonged, the flame stability will deteriorate, and the probability of ignition failure will increase, thereby affecting the use effect of the equipment.

[0026] like Figure 1-7 As shown: a flame weeding device with integrated remote control electronic ignition, the flame weeding device includes a burner device 4 and an electronic ignition control device 5, wherein the burner device 4 includes a flame nozzle 41 and a gas delivery pipe 42, the flame nozzle 41 is connected to the gas source through the gas delivery pipe 42 at its tail end, the injection diameter of the flame nozzle 41 is 60mm, the length is 108mm, the injection temperature is about 1200℃, and the gas delivery pipe 42 adopts a rubber plastic gas hose with good pressure bearing capacity; the electronic ignition control device 5 includes a wireless The wireless receiving controller 511, the transmission wire 52, the rectifier 53, and the ignition needle 54 located at the lower side of the flame nozzle 41, the wireless receiving controller 511 is connected to the rectifier 53 and the ignition needle 54 in turn through the transmission wire 52, the transmission wire 52 adopts the copper wire with stable signal transmission and low price, and the ignition needle 54 adopts the electric heat ignition needle that can ignite quickly in a low temperature environment; the wireless receiving controller 511 can start the rectifier 53 and the ignition needle 54, so that the ignition needle 54 can emit sparks toward the injection port of the flame nozzle 41 to ignite the gas ejected from the flame nozzle 41.

[0027] Based on the above structure, Figure 1 , 4 As shown in 5: the flame weeding device also includes a heat-insulating wind shield 3. A positioning and mounting hole for mounting a flame nozzle 41 is reserved on the top of the heat-insulating wind shield 3 with a trapezoidal structure. The main body of the flame nozzle 41 arranged obliquely forward extends into the heat-insulating wind shield 3 from the positioning and mounting hole; the ignition needle 54 is fixed on the heat-insulating wind shield 3 below the injection port side of the flame nozzle 41.

[0028] Furthermore, three exhaust holes are arranged on the left and right sides of the heat-insulating windproof cover 3, and four exhaust holes are arranged on the front side. The diameter of the air holes is 10-15mm, so that the heat-insulating windproof cover 3 can maintain sufficient oxygen content while reducing the influence of wind, which is conducive to the complete combustion of the gas.

[0029] Based on the above structure, Figure 1-2As shown: the electronic ignition control device 5 also includes an electric control box 51, in which a wireless receiving controller 511 and a battery pack 512 are arranged, and the battery pack 512 supplies power to the wireless receiving controller 511 whose response time is not more than 20ms. The electric control box 51 is installed on the top of the support frame 1, and a heat insulation wind shield 3 with a burner device 4 is also installed on the front side of the support frame 1, and the heat insulation wind shield 3 can be adjusted relative to the electric control box 51.

[0030] Based on the above structure, Figure 1-5 , 7: the support frame 1 includes an L-shaped plate 101 and a horizontal transverse adjustment rod 102, the L-shaped plate 101 that plays a supporting role and the horizontal transverse adjustment rod 102 that plays a supporting and adjusting role are both made of high-temperature resistant galvanized iron and are fixed by welding; the electric control box 51 is installed on the top of the vertical section of the L-shaped plate 101, and the horizontal transverse adjustment rod 102 is installed on the free end of the horizontal section of the L-shaped plate 101, and the heat-insulating wind shield 3 with the burner device 4 is installed on the horizontal transverse adjustment rod 102, and the heat-insulating wind shield 3 can adjust the horizontal position on the horizontal transverse adjustment rod 102.

[0031] Furthermore, a height adjustment orifice plate 2 is installed on the horizontal transverse adjustment rod 102, and the height adjustment orifice plate 2 can adjust the horizontal position on the horizontal transverse adjustment rod 102; a specific implementation is: the height adjustment orifice plate 2 and the horizontal transverse adjustment rod 102 are fixed with a U-shaped buckle, and when the horizontal position needs to be adjusted, the U-shaped buckle is loosened, and a new position is selected on the horizontal transverse adjustment rod 102 for fixing.

[0032] During flame weeding, because the grass will interfere with the flame and even extinguish the flame when the grass density is too high, the flame weeding device provided by the present invention is also equipped with a temperature sensor linked to the electronic ignition control device 5. The temperature sensor is used to sense the temperature of the flame weeding device when it is working, and when the temperature detected by the temperature sensor drops sharply (the reason for this situation is generally that the fire is extinguished), the temperature sensor can transmit a signal to link the electronic ignition control device 5 to re-ignite.

[0033] Regarding the setting position of the temperature sensor, one is that the temperature sensor follows the flame nozzle 41 and extends into the heat insulation wind shield 3 and is located at the rear side of the injection port. This setting method requires the temperature sensor to have high high temperature resistance, such as a temperature measurement range of 0-1300°C or a slightly lower range. At this time, the temperature sensor is used to detect the temperature of the injection port area of ​​the flame nozzle 41; the second is to set the temperature sensor at the top of the front side of the heat insulation wind shield 3 (i.e., the upper side of the air hole arranged on the front side). Since it is outside the heat insulation wind shield 3, the temperature sensor itself has lower high temperature resistance requirements, such as a temperature measurement range of 0-900°C or a lower range. At this time, the temperature sensor is used to detect the internal temperature of the heat insulation wind shield 3. All of the above schemes can be used, but are not limited to the above schemes.

[0034] The flame weeding device provided by the present invention, which is integrated with a remote-controlled electronic ignition function, can be installed on a traveling mechanism for use. Example

The battery pack 512 supplies power to the wireless receiving controller 511. The transmission wire 52 connects the wireless receiving controller 511, the rectifier 53, and the ignition needle 54. The rectifier 53 is installed on the horizontal lateral adjustment rod 102, and the ignition needle 54 is fixedly installed on the heat-insulating windproof cover 3 at the lower side of the flame nozzle 41.

The wireless receiving controller 511 and the battery pack 512 are fixed in the electric control box 51. The response time of the wireless receiving controller 511 is less than 20ms and the remote control distance is 120 meters. The transmission wire 52 adopts copper wire with more stable signal transmission and lower price.

[0038] like Figure 4-5 As shown: the height adjustment orifice plate 2 has 10 gears in total, and the adjustable height is 0-20cm. The heat insulation wind shield 3 adopts a trapezoidal body, and 28 air holes with a diameter of 15mm are evenly punched on the middle and upper parts of the left and right sides of the heat insulation wind shield 3, and 34 air holes with a diameter of 15mm are evenly punched on the lower part of the rear side of the heat insulation wind shield 3.

[0040] The working process of a flame weeding device with integrated remote-controlled electronic ignition function provided by the present invention is as follows: First, the flame weeding device with integrated remote-controlled electronic ignition function is moved to the area where the operation is required; the operating height of the heat-insulating windproof cover 3 is adjusted through the height-adjusting orifice plate 2 on the support frame 1 to adapt to the needs of different terrains. Then the operator first opens the gas tank valve, and then starts the electronic ignition control device 5 through the remote control device. After the wireless receiving controller 511 receives the remote ignition signal, it quickly starts the rectifier 53 and the ignition needle 54, so that the ignition needle 54 on the lower side of the flame nozzle 41 emits sparks toward the injection port of the flame nozzle 41 and ignites the gas; after the ignition is successful, the flame nozzle 41 will continue to spray high-temperature flames, and its injection temperature can reach 1200°C, causing the weeds to lose water and die. The air hole design of the heat-insulating windproof cover 3 ensures that the gas can be fully burned, and the trapezoidal cover structure can effectively reduce the influence of wind speed on the flame, and maintain the concentration and stable output of the flame. After the operation is completed, the operator closes the gas tank valve and stops working.
