Description
Technical Field
[0001] The invention relates to the technical field of flame weeders, and in particular to an orchard flame weeder. Background Art
[0002] When farmers are building orchards, they need to weed the orchards from time to time. The weeding operation is carried out by mechanical equipment. During the operation, tractors and other transport equipment are usually used to drive the weeders to clear the weeds near the roots of fruits and vegetables in the orchard. The weeding operation can provide good growth conditions for fruit trees. Among them, the cleaning forms include manual weeding, steam weeding and flame weeding.
[0003] Flame weeding and steam weeding work on the same principle, both using high temperatures to inactivate the active substances in weeds, thereby achieving the purpose of weeding. Traditional flame weeders are too simple, consisting of only a fuel tank, a conduit, an igniter, and a flame nozzle, which can only perform simple flame spraying operations. As a result, they cannot adapt to some complex orchard scenarios. For example, the positions of fruit trees in some orchards are complex and the intervals are different. If weeds in different positions need to be accurately acted on, workers need to have high control requirements for the transfer equipment. If the operation is not careful, the fruit trees may be damaged. Summary of the Invention
[0004] The present invention proposes an orchard flame weeder, which solves the problem in the related art that traditional flame weeders have a simple structure, cannot adapt to complex orchard scenes, and are prone to damaging fruit trees.

After the two weeding bodies move, they approach or move away from each other, and the weeding bodies extend into or out of the weeding channel. The bottom of the weeding body is provided with a flame vent.
[0006] As a further technical solution, it also includes: A movable frame is movably arranged on the weeding frame. After the two movable frames move, they approach or move away from each other, and the movable frames extend into or out of the weeding channel. The weeding body is movably arranged on the weeding frame through the movable frame.
[0007] As a further technical solution, the moving direction of the movable frame is perpendicular to the length direction of the weeding channel, and there are multiple weeding bodies, and the multiple weeding bodies are all movably arranged on the movable frame.
[0008] As a further technical solution, the movable frame is movably arranged at the bottom of the weeding frame, and the top of the weeding frame has a guide hole, and further comprises: a guide block, the guide block being arranged on the top of the movable frame near one end of the weeding channel, and the guide block being located in the guide hole; Among them, several weeding bodies are all movably arranged at the bottom of the mobile frame.
[0009] As a further technical solution, it also includes: A circulating belt is circulated at the bottom of the weeding frame, and a plurality of weeding bodies are moved and arranged at the bottom of the movable frame by the circulating belt. After the circulating belt circulates, the weeding bodies are driven to move.
[0010] As a further technical solution, the circulation direction of the circulating belt close to the weeding channel is parallel to the length direction of the weeding channel.
[0011] As a further technical solution, it also includes: A fuel tank is provided at the bottom of the weeding rack, the circulating belt circulates around the fuel tank, and the fuel tank is located between the plurality of weeding bodies, and the plurality of weeding bodies are all slidably and sealedly connected to the fuel tank.
[0012] As a further technical solution, it also includes: A limit frame is provided at the bottom of the weeding frame, the fuel tank passes through the limit frame, a circulation limit channel is formed between the fuel tank and the limit frame, and a plurality of weeding bodies pass through the circulation limit channel.
[0013] As a further technical solution, it also includes: The wheel body is rotatably arranged at the bottom of the weeding frame, and the height position of the bottom of the wheel body is lower than the height position of the blazing port.
[0014] As a further technical solution, the transfer connection body includes: A transfer connecting rod and two connecting frames, both of which are threadedly connected to the transfer connecting rod, and the two connecting frames are arranged at intervals, and the two weeding frames are respectively arranged at the bottom of the two connecting frames.
[0015] The working principle and beneficial effects of the present invention are: In the present invention, the flame weeder is fixedly connected to the transfer connection main body using a tractor or other transfer equipment during use, thereby synchronously driving two spaced weeding frames to move in the orchard, and spraying fire from the flame outlet at the bottom of the weeding main body to the weeds near the roots of the fruit trees, thereby achieving the purpose of weeding.
[0016] The weeding channel between the two weeding racks can be adjusted according to the actual needs of the orchard, so that the weeder can flexibly adapt to orchard rows of different widths and layouts, improving the adaptability and flexibility of the equipment.

Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one component with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."
[0025] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.
[0026] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0027] Reference Figures 1 to 7 , which is the first embodiment of the present invention, proposes an orchard flame weeder, including: a transfer connection body 1; two weeding racks 2, both of which are arranged on the transfer connection body 1, and a weeding channel 201 is formed between the two weeding racks 2; a weeding body 3, which is movably arranged on the weeding rack 2, and the two weeding bodies 3 move closer to or away from each other, and the weeding bodies 3 extend into or out of the weeding channel 201, and the bottom of the weeding body 3 has a flame nozzle 301.
[0028] In this embodiment, Figure 1 、 2 As shown, the flame weeder uses a tractor or other transfer equipment to fix the connection body 1 during use, thereby synchronously driving two spaced weeding frames 2 to move in the orchard, and the flame port 301 at the bottom of the weeding body 3 sprays fire to the weeds near the roots of the fruit trees to achieve the purpose of weeding.
[0029] The weeding channel 201 between the two weeding racks 2 can be adjusted according to the actual needs of the orchard, so that the weeder can flexibly adapt to orchard rows of different widths and layouts, thereby improving the adaptability and flexibility of the equipment. At the same time, in view of the complex positions and uneven spacing of fruit trees, the spacing between the two weeding racks 2 can also be adjusted in advance, which can be achieved by a number of spaced positioning holes or threaded rods. As a result, when weeding, the fruit trees can pass through the weeding channel 201 smoothly without being damaged by equipment parts or fire sources.
[0030] Furthermore, the weeding body 3 capable of spraying fire is moved and set on the weeding rack 2. The weeding bodies 3 on the two weeding racks 2 can move closer to or farther away from each other and extend into or out of the weeding channel 201, so that the flame can be more accurately controlled to cover the weeds near the roots of the fruit trees. The range of flame coverage can be adjusted according to the growth density and height of the weeds, ensuring accurate weeding while reducing damage to the roots of the fruit trees.
[0031] The use of flame weeding instead of chemical herbicides avoids pollution to the soil and environment, protects the ecological environment of the orchard, and meets the requirements of sustainable development. The mobile design of the weeding body 3, combined with the efficient weeding ability of the flame nozzle 301, greatly reduces the need for manual weeding and reduces labor costs.
[0032] Flame weeding can not only effectively remove weeds, but also eliminate pathogens and pest eggs on the surface of weeds, reducing the occurrence of diseases and pests, helping to maintain the ecological balance of the orchard, reducing resource consumption, and reducing dependence on water resources.
[0033] Furthermore, it also includes: a mobile frame 4, which is movably set on the weeding frame 2. After the two mobile frames 4 move, they move closer to or away from each other, and the mobile frames 4 extend into or out of the weeding channel 201. The weeding body 3 is movably set on the weeding frame 2 through the mobile frame 4.
[0034] In this embodiment, Figure 1 、 2As shown in Figures 3 and 5, the weeding main body 3 has a variety of movement modes on the weeding frame 2, such as using a cylinder to complete linear movement, a connecting rod mechanism to complete swinging, or a chain to drive it to move back and forth along a fixed trajectory. However, considering comprehensively, the movement of the weeding main body 3 has two purposes. One is to get closer to the weeding channel 201, that is, close to the roots of the fruit trees, to improve the accuracy of clearing weeds. The other is that when the tractor drives it to weed, the weeding main body 3 moves relative to the whole body, which can increase the processing time of the weeding main body 3 on the weeds in a certain area, so the two are distinguished.
[0035] A movable frame 4 is provided on the weeding frame 2 by means of a cylinder. The movable frame 4 moves within the guide rail, which also improves the movement stability. The movable frames 4 on the two weeding frames 2 can move closer to or away from each other, thereby achieving one of the purposes, that is, getting closer to the weeding channel 201 and the roots of the fruit trees, and the blazing port 301 is aimed at the weeds near the roots of the fruit trees, thereby improving the accuracy of weed cleaning; and the movement of the weeding body 3 is to achieve the purpose of increasing the time for the weeding body 3 to treat weeds in a certain area, so the weeding body 3 is movably provided on the weeding frame 2 through the movable frame 4.
[0036] Furthermore, the moving direction of the movable frame 4 is perpendicular to the length direction of the weeding channel 201 , and there are a plurality of weeding bodies 3 , which are all movably arranged on the movable frame 4 .
[0037] In this embodiment, Figure 1 、 2 As shown in Figures 3 and 5, the moving direction of the mobile frame 4 is further limited to be perpendicular to the length direction of the weeding channel 201. Because fruit trees are generally planted in a linear arrangement, the tractor drives the flame weeder to move along the direction of fruit tree planting. Therefore, the purpose of the mobile frame 4 is to make the flame nozzle 301 as quickly as possible to align with the weeds near the roots of the fruit trees under its driving action, thereby improving the accuracy and efficiency of weed cleaning.
[0038] A plurality of weeding bodies 3 are movable on the movable frame 4 in order to greatly improve the processing efficiency and cover weeds in a wider range.
[0039] Furthermore, the mobile frame 4 is movably arranged at the bottom of the weeding frame 2, and the top of the weeding frame 2 has a guide hole 202, and also includes: a guide block 5, the guide block 5 is arranged on the top of the mobile frame 4 near one end of the weeding channel 201, and the guide block 5 is located in the guide hole 202; wherein, several weeding bodies 3 are movably arranged at the bottom of the mobile frame 4.
[0040] In this embodiment, Figure 1 、 4As shown, in order to facilitate the smooth orientation of the blazing port 301 toward the ground, the movable frame 4 and the weeding body 3 are both arranged at the bottom of the weeding frame 2. Specifically, the movable frame 4 is movably arranged at the bottom of the weeding frame 2, and several weeding bodies 3 are movably arranged at the bottom of the movable frame 4. The weeding frame 2 is in the shape of a plate cover, which can protect the remaining components and prevent the driving components from being damaged during operation.
[0041] A guide hole 202 is also opened at the top of the weeding frame 2. On the one hand, a guide block 5 welded to the top of the mobile frame 4 close to the weeding channel 201 extends into the guide hole 202, and the guide hole 202 provides the stable limiting function required for the movement of the mobile frame 4. On the other hand, due to the welding position of the guide block 5, the entire mobile frame 4 and the components arranged thereon can be well supported by the weeding frame 2 because they are stably "hung" on the weeding frame 2 through the guide block 5. At the same time, in order to adapt to the moving displacement of the mobile frame 4, the guide block 5 is welded to the top of the mobile frame 4 close to the weeding channel 201 to avoid interference.
[0042] Furthermore, it also includes: a circulating belt 6, which is circulated and arranged at the bottom of the weeding frame 2. Several weeding bodies 3 are moved and arranged at the bottom of the mobile frame 4 through the circulating belt 6. After the circulating belt 6 circulates, it drives the weeding bodies 3 to move.
[0043] In this embodiment, Figure 1 、 2 As shown in , 3, 5~7, specifically, a circulating belt 6 in the form of a chain or the like is provided at the bottom of the weeding rack 2 to drive the movement of several weeding bodies 3, ensuring that the blast port 301 and the weeding rack 2 as a whole move relative to each other, thereby increasing the time for the weeding bodies 3 to treat weeds in a certain area when the weeding rack 2 moves, and also making full use of the area of the entire weeding rack 2 to expand the weed treatment range.
[0044] Furthermore, the circulation direction of the circulating belt 6 on the side close to the weeding channel 201 is parallel to the length direction of the weeding channel 201 .
[0045] In this embodiment, Figure 1 、 2 As shown in , 3, 5~7, the circulation direction of the circulation belt 6 has many forms, such as rectangle, triangle, circle, and the weeding rack 2 is in the shape of a plate cover, so the circulation belt 6 is most likely to be installed on a steel plate similar to a rectangle. In order to make full use of the area of the entire weeding rack 2, expand the weed treatment range, and at the same time increase the time for the weeding main body 3 to treat weeds in a certain area, the circulation direction of the circulation belt 6 close to the weeding channel 201 is set to be parallel to the length direction of the weeding channel 201. When the weeding rack 2 moves in one direction, the circulation belt 6 runs in the opposite direction, that is, the circulation belt 6 moves in the opposite direction close to the weeding channel 201.
[0046] Furthermore, it also includes: a fuel tank 7, which is arranged at the bottom of the weeding rack 2, and the circulating belt 6 circulates around the fuel tank 7. The fuel tank 7 is located between the multiple weeding bodies 3, and the multiple weeding bodies 3 are all slidably and sealedly connected to the fuel tank 7.
[0047] In this embodiment, Figure 2 、 3 As shown in Figures 5 to 7, in order to ensure the fuel required by the weeding main body 3 and meet the use of several groups of weeding main bodies 3 at the same time, the fuel tank 7 is set at the bottom of the weeding rack 2, and the circulating belt 6 circulates around the fuel tank 7. The fuel tank 7 is also located between several weeding main bodies 3, which is convenient for introducing the fuel in the fuel tank 7 into each weeding main body 3. At the same time, to prevent fuel leakage, the weeding main body 3 and the fuel tank 7 are slidingly sealed. Specifically, a mechanical pipeline dynamic seal can be used. A circle of through grooves is opened around the fuel tank 7, and a dynamic sealing ring is installed. Several groups of weeding main bodies 3 are sealed and connected to the dynamic sealing rings in the through groove, and the whole constitutes a part of the fuel tank 7. Then, when the circulating belt 6 drives several groups of weeding main bodies 3 to move, the fuel will not leak.
[0048] Furthermore, it also includes: a limit frame 8, which is set at the bottom of the weeding frame 2, the fuel tank 7 passes through the limit frame 8, a circulation limit channel 9 is formed between the fuel tank 7 and the limit frame 8, and several weeding bodies 3 pass through the circulation limit channel 9.
[0049] In this embodiment, Figure 2 、 3 As shown in Figures 5 to 7, although several groups of weeding bodies 3 are connected to the fuel tank 7 during the circulation process, there is still a risk of shaking, which leads to reduced processing accuracy. Therefore, it is necessary to improve the accuracy of the circulating movement of the weeding body 3. A limit frame 8 is welded at the bottom of the weeding rack 2. It can be L-shaped, avoiding components such as the circulation belt 6 and the fuel tank 7, and the fuel tank 7 passes through the limit frame 8 and forms a circulation limit channel 9 with it. Then, several weeding bodies 3 passing through the circulation limit channel 9 are limited, and can also contact the inner wall to further improve the limiting accuracy.
[0050] Furthermore, it also includes: a wheel body 10, which is rotatably arranged at the bottom of the weeding frame 2, and the height position of the bottom of the wheel body 10 is lower than the height position of the flame vent 301.
[0051] 9 In this embodiment, Figure 1 、 2 As shown in Figures 3, 6, and 7, since the overall weeding frame 2 tries to avoid friction with the ground during movement and improves its service life, a wheel body 10 is rotatably provided at the bottom of the weeding frame 2, which also plays a certain supporting role. At the same time, the height position of the bottom of the wheel body 10 is lower than the height position of the blazing port 301 to avoid the blazing port 301 from affecting the ground.
[0052] Furthermore, the transfer connection body 1 includes: a transfer connection rod 101 and two connection frames 102 . The two connection frames 102 are both threadedly connected to the transfer connection rod 101 , and the two connection frames 102 are arranged at intervals. The two weeding frames 2 are respectively arranged at the bottom of the two connection frames 102 .
[0053] In this embodiment, Figure 1 As shown, the transfer connection body 1 is divided into a transfer connection rod 101 and two connection frames 102. When working, the transfer connection rod 101 can be directly hung on the tractor through a hook or other fixed connection structure. The two connection frames 102 are inclined V-shaped designs and are respectively connected to the top of the two weeding frames 2 through bolts and other fasteners, thereby improving the overall installation convenience and subsequent maintenance.
[0054] In the early stage, the connecting rod 101 can be directly rotated and transferred. By using the principle of threaded connection, the threads of the two weeding racks 2 are rotated in opposite directions to control the distance between them. The weeding rack 2 is also at the bottom to facilitate the blaze port 301 to play a role.
[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
