Description

[0002] The statements herein are provided only to further provide context of the present application and are not necessarily prior art.

[0003] Each leaf axil of a tobacco plant usually carries 1-2 axillary buds, which are generally in a latent state before topping due to inhibition of apical growth. Once the topping operation is performed, the artificial removal of the inhibition of the axillary buds by the apical auxin, these latent axillary buds will quickly germinate and grow, and consume a large amount of nutrients and water of the leaf, thereby reducing the yield and quality of tobacco leaves. Therefore, the bud-inhibiting agent should be sprayed in time after tobacco topping, and as much as possible to be completed on the same day.

[0004] Due to the high residual characteristics of the bud-inhibiting agent, it cannot be sprayed onto the tobacco leaves, and conventional spraying machinery cannot be used. Moreover, the tobacco leaf axillary buds have a large degree of freedom, and it is difficult to mechanize the topping and bud-inhibiting operation by limiting the multiple degrees of freedom thereof. Therefore, the current tobacco topping and bud-inhibiting operation is completed by manual work, and the operation process adopts a two-person mode of one person for topping and one person for bud-inhibiting.

[0058] In this embodiment, the height recognition device uses a height recognition radar, which can emit radar waves and receive the reflected signals. The growth height of the crop plants affects the characteristics of the reflected radar waves, thereby achieving accurate recognition and measurement of the plant height.

[0059] The lifting device 3 includes a lifting driving mechanism, a linear motion pair 35, and a base 36. The lifting driving mechanism is connected with the linear motion pair 35, the bottom of the linear motion pair 35 is connected with the base 36, the entire lifting device is fixed on the base, and the base is installed at the front end of the fixed support. The linear motion pair is a lead screw and sliding block mechanism composed of a lead screw 34 and a sliding block. The sliding block is connected with the lead screw 34 and can move up and down along the lead screw. The lead screw is connected with the lifting driving mechanism. The sliding block of the linear motion pair is fixedly connected with the base 21 of the topping device and the bud inhibitor spraying device.

[0061] The topping plant recognition device 4 includes an adjusting support 41, a topping plant monitoring emitting element 42, and a topping plant monitoring receiving element 43. The adjusting support 41 is fixed to the base 36 of the lifting device 3, and the topping plant monitoring emitting element 42 and the topping plant monitoring receiving element 43 are fixed to the adjusting support 41.

[0062] Specifically, two adjusting supports 41 are provided, which are oppositely and spacedly arranged. The two adjusting supports are respectively installed on the two sides of the base 36 and are downwardly extended from the two sides of the base.

[0063] Each adjusting support 41 comprises a vertical support body 411 and a horizontal support body 412, the vertical support body 411 is fixedly connected with the base 36 at the top by fasteners, and the vertical support body 411 is connected with the horizontal support body 412 at the middle by a connecting joint 413, the horizontal support body 412 of one adjusting support 41 is fixedly connected with the topping plant monitoring emitting element 42, and the horizontal support body 412 of the other adjusting support 41 is fixedly connected with the topping plant monitoring receiving element 43.

[0064] The vertical support body 411 and the horizontal support body 412 are perpendicular to each other, the vertical support body 411 is vertically arranged, and the horizontal support body 412 is horizontally arranged. The connecting joint 413 is provided with a through hole for the vertical support body 411 and the horizontal support body 412 to pass through, the vertical support body 411 and the horizontal support body 412 can pass through the connecting joint 413, and the connecting joint 413 can fix the vertical support body 411 and the horizontal support body 412 by fasteners. In an optional embodiment, the connecting joint 413 penetrates the fasteners to tightly press the vertical support body 411 and the horizontal support body 412, so that the positions of the vertical support body 411 and the horizontal support body 412 are fixed.

[0065] The horizontal support body 412 can be adjusted up and down and front and back at the connecting position of the vertical support body 411, the mounting position of the connecting joint 413 on the vertical support body 411 and the horizontal support body 412 is changed, so that the position of the horizontal support body is adjusted, and the positions of the topping plant monitoring emitting element and the topping plant monitoring receiving element are adjusted.

[0066] In a preferred embodiment, the bottom of the vertical support body 411 is provided with a horizontal bend, which can prevent the connecting joint from being pulled out of the vertical support body.

[0067] The end of the horizontal support body 412 is provided with a horizontal bend, the topping plant monitoring emitting element 42 is fixed to the horizontal bend of the horizontal support body 412 of one adjusting support, and the topping plant monitoring receiving element 43 is fixed to the horizontal bend of the horizontal support body 412 of the other adjusting support. The positions of the topping plant monitoring emitting element 42 and the topping plant monitoring receiving element 43 at the connecting position of the horizontal support body 412 can be adjusted, so that the left and right positions of the topping plant monitoring emitting element 42 and the topping plant monitoring receiving element 43 can be adjusted, the distance between the topping plant monitoring emitting element 42 and the topping plant monitoring receiving element 43 is changed, and the distance between the two can be determined according to the height of the crops and the thickness of the stems.

[0068] The topping plant monitoring emitting element 42 and the topping plant monitoring receiving element 43 are oppositely arranged, the topping plant monitoring emitting element 42 can adopt an infrared emitter, and the topping plant monitoring receiving element 43 can adopt an infrared receiver.

[0069] For example, the infrared emitter and the infrared receiver are used to monitor the plants. When the topped plant passes between the infrared emitter and the infrared receiver, the light beam is broken by the stem of the plant, at which time the receiver generates a pulse, so that the topped plant can be monitored. After the topped plant is monitored, the plant growth retardant spraying device 5 is correspondingly moved to align with the topped plant to spray the plant growth retardant.

[0070] In addition, since the plant spacing may be inconsistent, the plant growth retardant spraying device 5 also needs to adjust its position according to the plant spacing. The plant spacing can be obtained by the following method: according to the relative moving speed of the plant and the device and the relative position of the front and rear two plants, the plant spacing between the front and rear plants is calculated; after the plant spacing is obtained, the position of the plant growth retardant spraying device 5 is dynamically adjusted to correspond to the topped plant more accurately.

[0071] In this process, the height recognition radar can obtain the position of the plant; the speed monitoring element (such as a speed sensor) can be fixedly arranged at the height recognition device to obtain the relative moving speed of the plant and the device. According to the monitoring of the plant by the infrared emitter and the infrared receiver, the movement of the plant growth retardant spraying device 5 is adjusted.

[0072] The plant growth retardant spraying device 5 includes a slide rail 51, a gantry plate 52, an electromagnetic valve 53, and a nozzle structure 54. The gantry plate 52 is slidably connected to the slide rail 51, and the slide rail 51 is horizontally arranged. The gantry plate 52 can move horizontally forward and backward along the slide rail 51. The nozzle structure 54 is fixed to the gantry plate 52, and the nozzle structure 54 is connected to a plant growth retardant supply device. The electromagnetic valve 53 is arranged at the nozzle structure 54. The plant growth retardant supply device can include a plant growth retardant container, which is connected to the nozzle structure 54 through a conveying pipe.

[0073] The gantry plate 52 is installed on the slide rail 51 through a pulley. The gantry plate 52 is fixedly arranged with the pulley, and the pulley is slidably connected to the slide rail.

[0074] Specifically, the slide rail 51 is installed on one side of the sliding block of the linear motion pair 35 of the lifting device 3 through a slide rail fixing bracket. The slide rail 51 and the base 21 of the topping device are installed on both sides of the sliding block. This design is conducive to the lifting device adjusting the working height of the topping device and the plant growth retardant spraying device at the same time.

[0075] In a preferred embodiment, a guide frame 37 is arranged on the lifting device 3. The guide frame 37 is vertically arranged, the end of the slide rail 51 is connected to the guide frame 37, and the slide rail 51 can move up and down along the guide frame 37. The guide frame can guide and support the slide rail, so that the movement of the plant growth retardant spraying device is more stable. The upper and lower ends of the guide frame 37 can be fixed to the lifting motor 31 and the base 36 of the lifting device 3 through a connecting plate.

[0076] The nozzle structure 54 and the electromagnetic valve 53 can be fixed to a metal bracket, which is fixed to the gantry plate 52. The electromagnetic valve 53 can be a 12-volt direct-current normally closed electromagnetic valve, which mainly controls the flow of the bud inhibition agent (start or stop) and allows the bud inhibition agent to flow through the port or be closed without leakage by means of a plunger. When not powered, the plunger is in the lower position, and the valve is closed. When powered, the plunger rises to allow the bud inhibition agent to flow.

[0077] The use of electromagnetic valves for intermittent operation helps to reduce the use of pesticides, reduce harm to the environment and operating personnel, and meet the requirements of sustainable agricultural development.

[0078] The bud inhibition agent spraying device 5 is located behind the topping device 2, and the height of the nozzle structure 54 is slightly higher than that of the topping knife. The nozzle structure needs to spray the bud inhibition agent above the stems that have been processed by the topping knife.

[0079] The nozzle structure 54 is provided with multiple spray holes, and multiple conical surfaces are arranged on the side in a circumferential direction. Each conical surface is provided with a spray hole, and the bottom is also provided with a spray hole, which can provide a uniform, round, and full spray mode and spray small-size droplets. In this embodiment, the multi-hole full-cone nozzle 41 is provided with 7 individual spray holes.

[0080] The device integrates radar height recognition, lifting device, and plant spacing recognition technology, and can simultaneously perform topping and bud inhibition operations, bringing significant advantages and convenience to tobacco production. First, when the crop plants are guided to the topping device by the lifting device, the height of the tobacco plants is accurately recognized and measured by the height recognition radar. The lifting device adjusts the position of the topping device and the bud inhibition agent spraying device according to this information, thereby achieving accurate topping and bud inhibition operations. Second, the topping plant recognition device installed at the front end of the bud inhibition agent spraying device uses infrared technology to locate the tobacco plants that have completed topping, determines the position of the stem incision of each crop plant, and then sends instructions to the bud inhibition agent spraying device to move, thereby spraying the bud inhibition agent directly on the top of the stem for bud inhibition.

[0081] In another typical embodiment of the present application, a method for precise target application of bud inhibition agent is proposed, which uses the precise target application device of bud inhibition agent as described above, and includes the following steps:

[0082] (1) The precise target application device of bud inhibition agent is installed on the top of the self-propelled chassis. When the chassis advances along the crop plants, the lifting device keeps the crop plants upright and then guides them to the topping device;

[0083] (2) According to the data measured by the height recognition device, the lifting device automatically adjusts the position of the topping device and the bud inhibition agent spraying device to ensure that they match the height of the top inflorescence of the plant;

[0084] (3) According to the detected plant top inflorescence height, the height position of the topping knife is adjusted so that the topping knife is located below 2-4 young leaves below the tobacco top inflorescence, and the topping operation is performed;

[0085] (4) The sensing distance between the topping plant monitoring emitting element and the topping plant monitoring receiving element of the topping plant recognition device is about 25 mm. When the light beam is broken by the tobacco plant that has completed the topping operation, the receiver generates a pulse (the light beam is broken), and at this time the crop plant that has completed the topping is detected;

[0086] (5) When the topping plant recognition device detects the crop plant that has completed the topping, the gantry plate drives the nozzle structure to move along the slide rail at a speed matching the ground speed of the self-propelled chassis, so as to realize accurate positioning of the plant, and then the electromagnetic valve of the bud suppression agent spraying device is energized to start the bud suppression operation, thereby ensuring accurate spraying of the bud suppression agent.

[0087] In a preferred embodiment, according to the relative movement speed of the plant and the device, the relative position of the front and rear plants, the plant spacing between the front and rear plants is calculated; after obtaining the plant spacing, the position of the bud suppression agent spraying device 5 is dynamically adjusted accordingly, so that it can more accurately correspond to the topped plant, and can accurately position each crop for bud suppression agent spraying.

[0088] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.

A topping plant identification device is fixed at the bottom of the lifting device, and the lifting device is also connected to a bud-inhibiting agent spraying device. The topping plant identification device includes an adjusting bracket, which fixes a topping plant monitoring transmitter and a topping plant monitoring receiver that are arranged opposite to each other. The bud-inhibiting agent spraying device includes a nozzle structure that is slidably connected to a slide rail. After the topping plant identification device monitors the crop plant that has been toppled, the nozzle structure moves along the slide rail to the top of the plant to spray the bud-inhibiting agent. The bud-inhibiting agent spraying device is located behind the topping device; A solenoid valve is installed at the nozzle structure; the nozzle structure is fixed to the gantry plate, the gantry plate is slidably connected to the horizontal slide rail, and the gantry plate can move horizontally back and forth along the slide rail. Two adjustable supports are provided, positioned opposite each other and spaced apart. Each adjustable support includes a vertical support body, the top of which is fixedly connected to a lifting device. The middle of the vertical support body is connected to a horizontal support body via a connecting joint. The horizontal support body of one adjustable support is fixedly connected to the topping plant monitoring transmitter element, and the horizontal support body of the other adjustable support is fixedly connected to the topping plant monitoring receiver element. The horizontal support body can be adjusted up and down and forward and backward at its connection position with the vertical support body, and the connection positions of the topping plant monitoring transmitter element and the topping plant monitoring receiver element with the horizontal support body are also adjustable. A horizontal bend is provided at the bottom of the vertical support body, and a horizontal bend is provided at the end of the horizontal support body. The topping device is fixedly equipped with a crop-lifting device, which includes two oppositely arranged crop-lifting components with a gap between them. When the precise application device for the sprout inhibitor is driven by a mobile chassis along the tall crops, the crop plants are received by the supporting device. The plants enter the gap between the two supporting components, guiding the crop stems to the smallest gap for fixation, keeping them upright and stabilizing their position. This provides precise positioning for subsequent topping operations. At this point, the topping device begins topping. The topping device includes a height recognition device, a topping blade, a power unit, and a base. The base has an L-shaped plate structure, with the topping blade installed below it. The topping blade is connected to the power unit, which drives the topping blade to rotate. The height recognition device is installed at both ends of the top of the base. After the supporting device guides the crop plants into the topping device, the height recognition device first measures the plant height, and then the lifting device adjusts the topping device to the appropriate height for topping. The topping plant monitoring transmitter and receiver are positioned relative to each other. The topping plant monitoring transmitter is an infrared transmitter, and the topping plant monitoring receiver is an infrared receiver. When the topping plant passes between the infrared transmitter and receiver, the light beam is interrupted by the plant stem, and the receiver generates a pulse, thus detecting the topping plant. After detecting the topping plant, the bud inhibitor spraying device moves accordingly to spray the bud inhibitor onto the topping plant. The plant spacing between the topping plants is calculated based on the relative movement speed of the plant and the device, and the relative positions of the two plants. After obtaining the plant spacing, the position of the bud inhibitor spraying device is dynamically adjusted accordingly.

2. The device for precise application of the sprout inhibitor as described in claim 1, characterized in that, The nozzle structure has multiple spray holes, and multiple conical surfaces are arranged circumferentially on the side of the nozzle structure. Each conical surface is provided with a spray hole, and a spray hole is also provided at the bottom of the nozzle structure.

3. The device for precise application of the sprout inhibitor as described in claim 1, characterized in that, The lifting device includes a lifting drive mechanism, which is connected to a linear motion pair. The bottom of the linear motion pair is connected to the base. The linear motion pair includes a lead screw, which is connected to a slider. The lead screw is connected to the lifting drive mechanism, and the slider is fixedly connected to a topping device and a sprout suppressant spraying device.

4. The device for precise application of the sprout inhibitor as described in claim 3, characterized in that, The lifting device is equipped with a guide frame, and the end of the slide rail is connected to the guide frame, and the slide rail can move up and down along the guide frame.
