Description

Technical Field

[0001] The utility model relates to the field of agricultural flame weeding, in particular to a portable combined flame weeding machine. Background Art

[0002] Weeding is an unavoidable topic in agricultural production. Weeds are one of the biggest natural enemies of crops. At present, pesticides are generally used to remove weeds in my country, and the killed weeds are naturally degraded in the field. The disadvantage of using pesticides for weeding is that it is easy to cause soil and water pollution and pesticide residues in food. At the same time, the continuous use of pesticides will also increase the resistance of pests. Therefore, some major agricultural countries abroad have begun to use flame weeding. The principle is to use agricultural machinery with a large number of flame spray guns to drive through the farmland at a relatively slow speed, and burn the entire farmland with high-temperature flames. This flame fuel is a clean combustible gas (such as propane). When burning, the flame temperature can reach 2,000 degrees Celsius, which can not only burn the weeds in the field to death and quickly degrade them, but also eliminate various harmful bacteria and insect eggs.

[0003] Although large flame weeders driven by agricultural machinery have high weeding efficiency, they are generally only suitable for large areas of plains, and are not suitable for small plots such as mountains and hills. Enshi has many mountains, small plots and large slopes, so small and portable flame weeders are needed. Conventional small flame weeders are generally backpack-type or hand-push-type. Pure backpacks or hand-push-type are applicable to small plots and places with many slopes like Enshi, but each has its own shortcomings: pure backpack-type, you need to carry the fuel tank all the time, when the small plot is relatively flat or when transporting on a flat road, you also need to carry it, the load is large when using it, and it is not labor-saving; pure hand-push-type is heavier overall when climbing a slope or crossing a ditch, and the passability is poor, especially the flame-throwing component that extends diagonally downward at the front end is easy to collide or conflict with the ground, affecting traffic. Utility Model Content

[0004] The utility model provides a portable combined flame weeder, aiming to overcome the above-mentioned deficiencies in the prior art to at least a certain extent.

[0005] The utility model solves the above-mentioned technical problem with the following technical solutions: A portable combined flame weeder comprises a trolley, a fuel tank and a flame spraying assembly, wherein the trolley comprises a support plate and wheels arranged on the left and right sides of the support plate, a baffle is arranged on the front side of the support plate, the fuel tank is placed on the support plate and is clamped and limited from the rear side by a restraining belt connected to the left and right sides of the baffle plate, the flame spraying assembly comprises a fixing rod arranged to be tilted forward, the upper end of the fixing rod is connected to the front side of the support plate, the lower end of the fixing rod is hinged to the upper end of the flip rod and a rotation-stopping positioning structure is arranged at the hinge, the lower end of the flip rod is fixedly connected to the middle part of the horizontal cross bar, a main fuel pipe with closed ends is fixed on the horizontal cross bar, a plurality of branch fuel pipes are connected to the pipe wall of the main fuel pipe, a flame spraying sleeve is connected at the lower end of the branch fuel pipe, the main fuel pipe is connected to the fuel tank through a fuel hose, a control valve is arranged on the fuel hose, a limiting member is arranged on the front side of the baffle plate, and the flip rod can be positioned by the limiting member after being rotated upward by an angle.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, it also includes a handheld flamethrower, the front end of which is a flamethrower head, and the rear end is a joint for easy connection with a gas hose. The handheld flamethrower is provided with a handheld portion and an opening and closing valve is provided near the handheld portion. The fuel tank is in a flat barrel shape for easy carrying, and two left and right carrying straps are connected to the fuel tank.

[0008] Furthermore, the handrail of the trolley is in the shape of a hollow long cylinder and has an openable and closable cover at the rear end, and the handheld flamethrower is placed in the inner cavity of the handrail.

[0009] Furthermore, the control valve is arranged on the handrail and close to the rear end of the handrail, and the fuel hose between the fuel tank and the control valve is connected to the control valve through a quick-release connector.

[0010] Furthermore, the anti-rotation positioning structure includes a positioning pin and a positioning hole. The upper end of the flip rod is hinged to the lower end of the fixed rod through a rotating shaft. The flip rod and the fixed rod are correspondingly provided with the positioning holes. When the positioning pin is inserted into the corresponding positioning hole, anti-rotation positioning is achieved between the flip rod and the fixed rod.

[0011] Furthermore, the limiting member is a wind hook, one end of which is movably connected to the front side of the baffle, and the other end is provided with an anti-detachment hook, and a hanging ring cooperating with the anti-detachment hook is provided on the lower end of the flip rod or the horizontal cross bar.

[0012] Furthermore, it also includes a pressing plate, which is fixedly connected to the horizontal cross bar and extends obliquely downward. The pressing plate is located at the bottom of each flamethrower sleeve, and the lowermost end of the pressing plate is lower than the lowermost end of the flamethrower sleeve.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The flame spraying assembly arranged at the front end of the flame weeder comprises a fixed rod and a flip rod. The flip rod can be flipped upward at an angle relative to the fixed rod and then positioned with the baffle on the vehicle through a limiter. The flame spraying sleeve and other structures that originally extend obliquely to the front side and lower side and are closer to the ground can be flipped upward away from the ground. In this way, when the flame weeder is pushed, the front end flame spraying assembly is not easily restricted by the collision with the ground after being flipped and retracted, so the passability is better, which is convenient for the movement and transfer of the entire device. The fuel tank is a heavier component in the entire device. When it is transferred on a flat road or used in a flat field, It can be placed on the pallet of a cart and limited by the restraining belt, and then pushed manually, which is more labor-saving; when it is necessary to climb a slope or pass a ditch, pushing and walking is impossible or very laborious, and the fuel tank can be carried on the back through the carrying belt. The lighter cart without the fuel tank is obviously easier to transfer; after the flame weeder is transferred to the target field, if the plot is too small or it is inconvenient for a cart to enter and use it, the handheld flamethrower can be assembled with the fuel tank on the back through the fuel hose and the cart can be parked at the end of the field, which has better applicability and a relatively simple overall structure.

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] In the description of the present invention, if terms indicating orientation such as "up", "down", "left", "right", "top", "bottom", "inside" and "outside" are used, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] like Figures 1 to 3 As shown, the utility model provides a portable combined flame weeder, including a trolley, a fuel tank 1 and a flame spraying assembly, the trolley includes a support plate 2 and wheels 3 arranged on the left and right sides of the support plate 2, a baffle plate 4 is arranged on the front side of the support plate 2, the fuel tank 1 is placed on the support plate 2 and is clamped and limited from the rear side by a restraining belt 5 connected to the left and right sides of the baffle plate 4, the flame spraying assembly includes a fixing rod 6 arranged forwardly, the upper end of the fixing rod 6 is connected to the front side of the support plate 2, the lower end of the fixing rod 6 is hinged to the upper end of the flip rod 7, and the hinge is provided with a The anti-rotation positioning structure is characterized in that the lower end of the flip rod 7 is fixedly connected to the middle part of the horizontal cross bar 8, a main fuel pipe 9 with closed ends is fixed on the horizontal cross bar 8, a plurality of branch fuel pipes 10 are connected to the pipe wall of the main fuel pipe 9, a flamethrower sleeve 11 is connected to the lower end of the branch fuel pipe 10, the main fuel pipe 9 is connected to the fuel tank 1 through a fuel hose 12, a control valve 13 is provided on the fuel hose 12, a limit piece 14 is provided on the front side of the baffle 4, and the flip rod 7 can be positioned by the limit piece 14 after being rotated upward by an angle.

[0023] It should be noted that the baffle is located on the front side of the support plate, and is curved in an arc shape to provide semi-enclosed protection for the fuel tank at the rear. On the one hand, it prevents the fuel tank from falling from the front side of the support plate, and on the other hand, it prevents the heat from the flame weeding operation of the front flame-throwing assembly from having an adverse effect on the fuel tank. The left and right sides of the baffle are connected with restraints, which can be elastic or inelastic. Preferably, one end is fixedly connected to one side of the baffle, and the other end is hooked to the other side of the baffle through a hook. The fuel tank stores clean fuel, preferably propane or liquefied petroleum gas, or ethanol.

[0024] In one embodiment of the present invention, a handheld flamethrower 15 is also included. Figure 3As shown, the front end is a flamethrower head 16, and the rear end is a joint for connecting with a gas hose. The handheld flamethrower 15 is provided with a handheld portion 17 and an opening and closing valve 18 is provided near the handheld portion 17. The fuel tank 1 is a flat barrel shape for easy carrying, and the fuel tank 1 is connected to two left and right carrying straps 19.

[0025] It should be noted that the flat barrel-shaped gas tank is similar to the commonly used backpack medicine barrel structure and has the advantage of being easy to carry. The length of the handheld flamethrower is about 1 to 1.2 m, and is preferably in the shape of a straight rod.

[0026] In one embodiment of the present invention, Figure 1 and 2 As shown, the handrail 20 of the trolley is in the shape of a hollow long cylinder and has an openable and closable cover 21 at the rear end, and the handheld flamethrower 15 is placed in the inner cavity of the handrail 20 .

[0027] It is understandable that the opening size of the hollow cavity of the handrail is larger than the thickest part of the handheld flamethrower, so that the handheld flamethrower can be easily placed in the inner cavity of the handrail and can also be easily taken out. For example, after the handheld flamethrower is placed in the inner cavity of the handrail, the tail end of the handheld flamethrower should be closer to the rear end opening of the handrail. When not in use, the handheld flamethrower is hidden in the handrail and does not take up space. When in use, it can be directly taken out, which is more convenient.

[0028] In one embodiment of the present invention, the control valve 13 is disposed on the handrail 20 and close to the rear end of the handrail 20 , and the fuel hose 12 between the fuel tank 1 and the control valve 13 is connected to the control valve 13 via a quick-release connector 22 .

[0029] It should be noted that after the quick-release connector is disconnected from the control valve, it should be able to be conveniently connected to the connector of the handheld flamethrower, thereby conveniently realizing the assembly of the fuel tank and the handheld flamethrower.

[0030] In one embodiment of the utility model, the anti-rotation positioning structure includes a positioning pin 23 and a positioning hole. The upper end of the flip rod 7 is hinged to the lower end of the fixed rod 6 through a rotating shaft 24. The flip rod 7 and the fixed rod 6 are correspondingly provided with the positioning holes. When the positioning pin 23 is inserted into the corresponding positioning hole, the anti-rotation positioning is achieved between the flip rod 7 and the fixed rod 6.

[0031] It is easy to understand that the anti-rotation positioning structure is not limited to the above-mentioned positioning pin and positioning hole matching form, and can also be achieved by a locking bolt or other common locking structures.

[0032] In one embodiment of the utility model, the limiting member 14 is a wind hook, one end of which is movably connected to the front side of the baffle 4, and the other end is provided with an anti-detachment hook, and a hanging ring 25 cooperating with the anti-detachment hook is provided on the lower end of the flip rod 7 or the horizontal cross bar 8.

[0033] It should be noted that the so-called wind hook is a commonly used rod with a ring at one end and a hook at the other end, which is usually used on windows to prevent the window sash from moving. In the utility model, the wind hook is used to position the turned-up flame-throwing assembly so that it remains in a stowed state away from the ground, so that the trolley can move more smoothly when being pushed. It is understandable that the limiting member is not limited to the wind hook, but can also be a fixed rope or spring, etc.

[0034] In one embodiment of the present invention, Figure 1 and 2 As shown, it also includes a pressing plate 26, which is fixedly connected to the horizontal cross bar 8 and extends obliquely downward. The pressing plate 26 is located at the bottom of each of the flame-spraying sleeves 11, and the lowermost end of the pressing plate 26 is lower than the lowermost end of the flame-spraying sleeve 11.

[0035] It should be noted that the pressure plate has at least two functions in the utility model. One is that when the cart is moving, the pressure plate that protrudes relatively forward can push down the plants in front and expose the relatively lower rhizome of the plant. The flamethrower sleeve is aimed at the rhizome to spray fire for better weeding effect. At the same time, the pressure plate also contacts the raised earth mound or the more protruding plant earlier than the flamethrower sleeve, which has a certain effect of preventing the flamethrower sleeve from being blocked. The other is that the pressure plate plays a supporting role. When the weeder suspends operation, the cart tilts forward to make the pressure plate touch the ground for support. The pressure plate and the two wheels form a three-point support so that the cart can be placed stably without falling over.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
