Description

Technical Field

[0001] The invention relates to the technical field of agricultural spraying equipment, and in particular to a directional interval spraying device for intercropping crops. Background Art

[0002] Intercropping refers to the planting of different types of crops in different planting proportions on the same land. For example, planting corn and soybeans in the gaps between corn fields can not only increase the utilization rate of farmland, but also avoid the problem of soil nutrient loss caused by planting a single crop on farmland.

[0003] Due to the different physical and chemical properties of different crops, the required pesticide components are different. Therefore, when intercropping farming methods are adopted, in order to avoid mutual interference of pesticides, large-scale single pesticide spraying cannot be carried out. At the same time, the pesticide spraying time of different crops is not fixed. If large-scale spraying is carried out, the drug resistance of some crops will increase. To address this problem, the existing solution is usually to use artificial isolation, exposing the crops that need to be sprayed with pesticides, and using isolation parts to cover the crops that do not need to be sprayed with pesticides, and then large-scale spraying is carried out. This method is time-consuming and labor-intensive and requires high labor costs.

[0021] refer to Figures 1 to 15 , a directional interval spraying device for intercropping crops, comprising a vertical mounting plate 1, an L-shaped mounting plate 2, a first horizontal plate 3, a liquid storage tank 15, a roller 5, a first connecting plate 10, a second connecting plate 12, a horizontal guide rail 11, a T-shaped spray head 22, a first movable isolation plate 21, a second movable blocking plate 6, a third movable isolation plate 7, a fixed isolation plate 20, a driving mechanism, a stirring mechanism, a first unfolding mechanism, a second unfolding mechanism, a third unfolding mechanism, and a sliding mechanism; The upper ends of the two vertical mounting plates 1 are fixedly mounted with the horizontal plate of the same L-shaped mounting plate 2, and the rear walls of the two vertical mounting plates 1 are respectively fixedly connected to the front walls of the vertical plates of the L-shaped mounting plate 2; A first gap is left between the two vertical mounting plates 1, and the two vertical mounting plates 1 are used to support the L-shaped mounting plate 2, and the L-shaped mounting plate 2 is used to support the liquid storage tank 15 described later; Liquid storage tanks 15 are installed on both sides of the upper end of the horizontal plate of the L-shaped mounting plate 2. A stirring mechanism is installed in each of the two liquid storage tanks 15. The liquid storage tanks 15 are used to load the medicine mixture for spraying, and the concentration of the mixture is made more uniform under the drive of the stirring mechanism. First connecting plates 10 are respectively vertically mounted on both ends of the rear wall of the vertical plate of the L-shaped mounting plate 2. Two rollers 5 are rotatably mounted on the outer walls of the two first connecting plates 10. The rollers 5 are used to support the device and facilitate the movement of the device. When the device moves, the rollers 5 also drive the stirring mechanism to start stirring the liquid medicine mixture in the liquid storage tank 15 in real time. The two rollers 5 near the liquid storage tank 15 respectively drive the two stirring mechanisms to work by rotating; A second connecting plate 12 is installed between the two first connecting plates 10, and the second connecting plate 12 is fixed on the rear wall of the vertical plate of the L-shaped mounting plate 2; A first horizontal plate 3 is installed on the rear wall of the horizontal plate of the L-shaped mounting plate 2. The first horizontal plate 3 is arranged above the two first connecting plates 10 and the second connecting plate 12. The first horizontal plate 3 is used to install the sliding mechanism described later. Two T-shaped nozzles 22 are slidably mounted on the first horizontal plate 3. The two T-shaped nozzles 22 are driven to slide by a sliding mechanism. The two T-shaped nozzles 22 are connected to two liquid storage tanks 15 respectively. The two T-shaped nozzles 22 start to slide under the drive of the sliding mechanism, so as to adapt to the spraying area after the isolation plate is unfolded. The lower end of the second connecting plate 12 is provided with a mounting groove 1201, and a fixed isolation plate 20 is fixedly installed in the mounting groove 1201; First movable isolation plates 21 are movably mounted on both sides of the fixed isolation plate 20, and the two first movable isolation plates 21 are movable on the inner sides of the two first connecting plates 10 respectively; The two first movable isolation plates 21 are driven to slide by the first unfolding mechanism. The two first movable isolation plates 21 move on both sides of the fixed isolation plate 20 under the drive of the first unfolding mechanism, so that the distance between them and the fixed isolation plate 20 changes as they begin to slide. The fixed isolation plate 20 is used to separate the two first movable isolation plates 21 into two spraying areas. A driving mechanism is installed on the upper end of the second connecting plate 12; The first unfolding mechanism is driven to work by the driving mechanism, and the driving mechanism is used to drive and limit the first unfolding mechanism; The sliding mechanism is driven to work by the first unfolding mechanism.

The outer sides of the two first connecting plates 10 are respectively movably mounted with second movable isolation plates 6; The two second movable isolation plates 6 are driven to slide by the second unfolding mechanism. The two second movable isolation plates 6 slide outside the two first movable isolation plates 21 under the drive of the second unfolding mechanism, so that a separate isolation area is formed between the first movable isolation plates 21 and the second movable isolation plates 6; The second unfolding mechanism is driven to work by the first unfolding mechanism; The outer sides of the two second movable isolation plates 6 are respectively movably mounted with third movable isolation plates 7; The two third movable isolation plates 7 are driven to slide by the third unfolding mechanism, and the two third movable isolation plates 7 are driven by the third unfolding mechanism to form separate isolation areas with the two second movable isolation plates 6 respectively; The third unfolding mechanism is driven to work by the second unfolding mechanism.

[0022] The stirring mechanism comprises a first sprocket 4, a second sprocket 401, a stirring rod 16, a first bevel gear 27, and a second bevel gear 28; The four rollers 5 are rotatably mounted on the outer walls of the two first connecting plates 10 via wheel shafts; The second sprockets 401 are fixedly mounted on the two wheel shafts close to the liquid storage tank 15, and the first sprockets 4 are respectively mounted on the front sides of the two second sprockets 401; Two first sprocket wheels 4 are rotatably arranged on the outer sides of the two vertical mounting plates 1 respectively through first rotating shafts; The two second sprockets 401 are respectively sleeved and meshed with chains on the outer sides of the two first sprockets 4; The other ends of the two first rotating shafts rotate and penetrate the two vertical mounting plates 1 to install the second bevel gears 28; The upper ends of the two second bevel gears 28 are respectively meshed with the first bevel gears 27; Two first bevel gears 27 are respectively rotatably arranged on both sides of the lower end of the horizontal plate of the L-shaped mounting plate 2 through the second rotating shaft; The other ends of the two second rotating shafts respectively rotate the horizontal plate that passes through the L-shaped mounting plate 2 and the bottom walls of the two liquid storage tanks 15, and stirring rods 16 are installed. The connection between the two second rotating shafts and the bottom walls of the two liquid storage tanks 15 is respectively installed with anti-leakage gaskets, whose function is to prevent water leakage of the liquid storage tanks 15. This is the prior art and will not be described here. The two stirring rods 16 are respectively rotated in the two liquid storage tanks 15. During the rolling process, the two rollers 5 respectively drive the two second sprocket wheels 401 coaxially fixed thereto. The second sprocket wheels 401 on both sides respectively transmit the rotational driving force to the two first sprocket wheels 4 through chains, so that the two first sprocket wheels 4 start to rotate, and the two first sprocket wheels 4 respectively drive the second bevel gears 28 coaxially installed thereto by rotation, and the two second bevel gears 28 respectively drive the two first bevel gears 27 meshing therewith by rotation, and the two first bevel gears 27 respectively drive the two stirring rods 16 coaxially installed thereto by rotation to start rotating, thereby achieving mixing of the liquid medicine mixture in the liquid storage tank 15.

[0023] The first unfolding mechanism comprises an I-shaped slider 19, a second horizontal plate 11, a first connecting rod 13, and a sliding rod 14; A second horizontal plate 11 is fixedly installed between the upper ends of the two first connecting plates 10; The second horizontal plate 11 is arranged at the front side of the first horizontal plate 3, and a second gap is left between the first horizontal plate 3 and the second horizontal plate 11; A third gap is left between the second horizontal plate 11 and the second connecting plate 12; The second horizontal plate 11 is provided with a first rectangular through slot 1101; The first rectangular through slot 1101 is slidably engaged with two vertical plates of I-shaped sliders 19; The upper ends of the upper horizontal plates of the two I-shaped sliders 19 are respectively installed with first connecting shafts, and the outer sides of the two first connecting shafts are respectively rotatably sleeved with the first ends of the first connecting rods 13; A slide bar 14 is movably mounted above the second connecting plate 12, and the slide bar 14 is slidably disposed in the third gap; The middle part of the lower end of the second horizontal plate 11 and the upper end of the second connecting plate 12 are fixedly connected via a fixing plate 1202; A rectangular through hole 1203 is installed on the fixed plate 1202, and the slide rod 14 is slidably arranged to penetrate the rectangular through hole 1203; Second connecting shafts are respectively installed on both sides of the first end of the sliding rod 14; The second ends of the two first connecting rods 13 are rotatably sleeved on the two second connecting shafts respectively; The slide bar 14 is driven to slide by the driving mechanism; The lower horizontal plates of the two I-shaped sliders 19 are respectively fixedly connected to one side of the upper ends of the two first movable isolation plates 21; The two first movable isolation plates 21 respectively drive the sliding mechanism to work through sliding. The slide rod 14 starts to slide under the drive of the driving mechanism and drives the two first connecting rods 13 to deflect during the sliding process. During the deflection process, the two first connecting rods 13 respectively drive the two I-shaped sliders 19 to start reciprocating sliding along the two first rectangular through grooves 1101. The cooperation between the first rectangular through grooves 1101 and the I-shaped sliders 19 ensures that the I-shaped sliders 19 will not fall off during the sliding process. During the reciprocating sliding process, the two I-shaped sliders respectively drive the two first movable plates 21 fixed thereto to start reciprocating sliding.

[0024] The driving mechanism comprises a first mounting block 201, a second mounting block 1401, a crank handle 17, and a threaded rod 18; A second mounting block 1401 is mounted on the upper end of the slide bar 14, and the second mounting block 1401 is movably disposed in the second gap; A first mounting block 201 is installed between the two liquid storage tanks 15; The first mounting block 201 is fixedly arranged at the middle part of the upper end of the horizontal plate of the L-shaped mounting plate 2; A crank 17 is rotatably mounted on the front wall of the first mounting block 201, and a threaded rod 18 is fixedly mounted on the output end of the crank 17; The threaded rod 18 and the second mounting block 1401 are threadedly connected; The end of the threaded rod 18 is rotatably connected to the front wall of the second horizontal plate 11. By rotating the crank 17, the crank 17 drives the threaded rod 18 fixedly connected thereto to start rotating. Since the crank 17 is rotatably mounted on the first mounting block 201, when the threaded rod 18 rotates, it drives the second mounting block 1401 to start sliding back and forth in the second gap. The sliding rod 14 fixedly mounted on the second mounting block 1401 now has the ability to slide back and forth.

During the reciprocating sliding of the two first movable isolation plates 21, the two first T-shaped sliders 2101 fixedly connected thereto also slide reciprocatingly in the two second rectangular through grooves 301. During the reciprocating sliding, the two first T-shaped sliders 2101 respectively drive the two T-shaped nozzles 22 fixedly installed thereto to start reciprocating sliding. During the reciprocating sliding, the spraying position of the T-shaped nozzle 22 is always between the first movable isolation plate 21 and the fixed isolation plate 20. The first rectangular nozzle 2201 and the second rectangular nozzle 2202 move with the second movable isolation plate 6 and the third movable isolation plate 7. Their function is to spray the area between the second movable isolation plate 6 and the third movable isolation plate 7.

[0026] The second unfolding mechanism comprises a second connecting rod 9, a third connecting rod 8, a second T-shaped slider 26, a first telescopic outer rod 2601, and a first telescopic inner rod 601; The upper ends of the horizontal plates of the two T-shaped nozzles 22 are respectively installed with third connecting shafts, and the outer sides of the two third connecting shafts are respectively rotatably sleeved with the first ends of the second connecting rods 9; First connecting frames are respectively installed at the rear ends of the outer walls of the two first connecting plates 10; The first ends of the third connecting rod 8 are rotatably mounted in the two first connecting frames respectively; The middle parts of the upper ends of the two third connecting rods 8 are respectively installed with second connecting frames 801, and the upper ends of the two second connecting frames 801 are respectively installed with fourth connecting shafts; The second ends of the two second connecting rods 9 are rotatably sleeved on the outer sides of the two fourth connecting shafts respectively; The lower ends of the two fourth connecting shafts rotate through the two second connecting frames 801 and are rotatably connected to the upper ends of the two second movable isolation plates 6; The outer walls of the two first connecting plates 10 are respectively provided with first T-shaped slide grooves 1001, and the two first T-shaped slide grooves 1001 are respectively provided below the two first connecting frames, and the horizontal plates of the second T-shaped sliders 26 are respectively slidably installed in the two first T-shaped slide grooves 1001; First telescopic outer rods 2601 are respectively installed on the outer walls of the vertical rods of the two second T-shaped slide blocks 26. The two first telescopic outer rods 2601 are respectively arranged above the horizontal pipes of the two second L-shaped water spraying conduits 24. First telescopic inner rods 601 cooperating with the first telescopic outer rods 2601 are respectively installed on the inner walls of the two second movable isolation plates 6. The two first telescopic inner rods 601 are slidably disposed in the two first telescopic outer rods 2601 respectively; The two third connecting rods 8 drive the third unfolding mechanism to work by rotating respectively. The two T-shaped nozzles 22 drive the second connecting rods 9 on both sides to start deflecting during the reciprocating sliding process. The two second connecting rods 9 drive the third connecting rods 8 on both sides to start deflecting during the deflection process. Since the rotation center of the third connecting rods 8 on both sides has been determined, when the second connecting rods 9 on both sides drive the third connecting rods 8 on both sides to start rotating around the rotation center during the deflection process, the two second movable isolation plates 6 located at the lower ends of the two third connecting rods 8 also start to deflect along with the two third connecting rods 8. At this time, the two second movable isolation plates 6 located in the two first T-shaped slide grooves 1001 are fixed to the two second movable isolation plates 6 on the outside through the telescopic rod. Therefore, when the two second movable isolation plates 6 are in the process of unfolding, the second movable isolation plate 6 can always be in a parallel position with the first connecting plate 10. When it is unfolded, the distance between the second movable isolation plate 6 and the adjacent first connecting plate 10 becomes larger to form an isolation area.

[0027] The third deployment mechanism comprises a second telescopic inner rod 701 and a second telescopic outer rod 2602; The upper ends of the two third movable isolation plates 7 are respectively installed with fifth connecting shafts, and the second ends of the two third connecting rods 8 are respectively rotatably sleeved on the outer sides of the two fifth connecting shafts; Second T-shaped sliding grooves are respectively provided on the outer walls of the two second movable isolation plates 6; A horizontal plate with a second T-shaped sliding block is slidably installed in each of the two second T-shaped sliding grooves; Second telescopic outer rods 2602 are respectively installed on the outer walls of the vertical plates of the two second T-shaped sliding blocks; The inner walls of the two third movable isolation plates 7 are respectively mounted with second telescopic inner rods 701, and the two second telescopic inner rods 701 are respectively arranged above the horizontal pipes of the two third L-shaped water spraying conduits 25; The two second telescopic inner rods 701 are slidably disposed in the two second telescopic outer rods 2602 respectively; Several expansion and deployment mechanisms are respectively installed on the outer sides of the two third movable isolation plates 7. The several expansion and deployment mechanisms located on one side are driven to work by the third connecting rod 8 located on the same side. During the rotation process, the two third connecting rods 8 respectively drive the third movable isolation plates 7 at their second ends to start rotating. During the movement process, the third movable isolation plate 7 maintains a sliding trajectory that is always parallel to the second isolation plate 6 using the same principle as the second movable isolation plate 6.

[0028] The expansion and unfolding mechanism includes an expansion partition 702, an expansion connecting rod 802, an expansion telescopic outer rod, and an expansion telescopic inner rod; The outer sides of the second ends of the two third connecting rods 8 are respectively fixedly mounted with expansion connecting rods 802, and the lower ends of the two expansion connecting rods 802 are rotatably mounted with a plurality of expansion partitions 702 at equal intervals; A third T-shaped slide groove is respectively provided on the outer wall of the plurality of expansion partitions 702, and a third T-shaped slide block is slidably installed in each of the plurality of third T-shaped slide grooves; The outer side walls of the third T-shaped sliders are respectively fixed with expansion telescopic outer rods, and the side walls of the expansion partitions 702 adjacent to the expansion telescopic outer rods are respectively installed with expansion telescopic inner rods, and the expansion telescopic inner rods are respectively slidably arranged in the expansion telescopic outer rods. Fig.13 The second ends of the third connecting rods 8 on both sides can be extended indefinitely, and the extended parts are extension connecting rods 802. Users can choose extension connecting rods 802 of different lengths according to actual needs. A number of extension partitions 702 are rotatably installed on the extension connecting rods 802 at equal intervals. Each extension partition 702 moves on the outside of the third movable isolation plate 7 according to the same principle as mentioned above, so as to achieve the purpose of dividing the spraying area into multiple areas. Each extension isolation plate 702 is also equipped with a rectangular nozzle for connecting to the liquid storage tank 15 through a hose, so as to realize the spraying of multiple isolation zones.

[0029] Implementation method of the present invention: Different drugs for spraying different crops are respectively put into two liquid storage tanks 15, and different lengths of extension connecting rods 802 are selected according to actual conditions, and the spray heads between each isolation plate are respectively connected to the two liquid storage tanks 15 through hoses in an interlaced manner; Rotate the crank 17, and the two first movable isolation plates 21 are expanded outwards, leaving different areas between the two first movable isolation plates 21 and the fixed isolation plates 20. When the two first movable isolation plates 21 are expanded outwards, the two second movable isolation plates 6 and the third movable isolation plate 7 are expanded at the same time, and the plurality of expansion isolation plates 702 are also expanded along with the third movable isolation plates 7 on both sides; At this time, there will be equal-sized spraying areas between the isolation plates. When there are only two crops interplanted in the target farmland, open the valves on the upper ends of the spray heads and push the equipment forward; Ensure that the isolation plate moves between the crops during the forward movement of the equipment. During the forward movement of the equipment, the stirring mechanism located in the two liquid storage tanks 15 rotates as the equipment moves, thereby stirring and mixing the liquid medicine mixture in the liquid storage tanks 15. Since the spraying area between each isolation plate is connected to a different liquid storage tank 15, the intercropping spraying of two crops can be achieved as the equipment moves forward, and the different sprayed liquids will be isolated by the two adjacent isolation plates to avoid cross spraying.

[0030] After the spraying operation, the user rotates the crank handle 17 in the opposite direction, and the isolation plates are all retracted to both sides of the device, which greatly reduces the occupied space and is convenient for storage.

[0031] The stirring mechanism of the present invention can move forward with the equipment to stir the pesticide in the liquid storage tank to balance its concentration. The first movable isolation plate, the second movable isolation plate and the third movable isolation plate of the present invention can divide the farmland into several areas under the drive of the first unfolding mechanism, the second unfolding mechanism and the third unfolding mechanism respectively. Several areas are separated and blocked by the isolation plates, thereby ensuring that there is no cross-application of pesticides during the spraying process. The sliding mechanism of the present invention will also slide with the unfolding mechanism and drive several nozzles to slide to different areas respectively to realize the spraying operation.

[0032] 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 principle of the present invention should be included in the protection scope of the present invention.
