Description

Technical Field

[0001] The technical field of plant protection operation machinery and equipment specifically relates to a multi-operation mode boom sprayer suitable for switching between single cropping and compound intercropping spray modes. Background Art

[0002] Boom sprayers have always been one of the main contents of agricultural machinery research and development. Common boom sprayers can only be used for spraying operations in single-crop mode. Under the background of vigorously promoting corn and soybean strip-shaped composite planting in the country, conventional plant protection machinery is difficult to meet agronomic requirements. Corn is a grass plant and soybean is a broad-leaved crop. The two will affect each other when using post-emergence stem and leaf herbicides. In the strip-shaped composite planting mode, baffles need to be installed on the boom to reduce the impact of droplet drift on adjacent crops.

[0003] Purchasing new crop protection equipment will increase the burden on farmers, so it is necessary to modify the conventional single-crop boom sprayer so that it can meet the agronomic requirements of both conventional single-crop planting and corn and soybean strip composite planting without purchasing a new vehicle. Based on the above problems, it is necessary to provide a multi-operation mode boom sprayer and its operation method.

[0004] Moreover, the existing single-crop spraying and combined-crop spraying switching method can only be achieved by replacing the spray rod at the end of the sprayer. The switching speed is slow and two sets of spray rod devices need to be prepared. The purchase cost is high and the switching method is troublesome. Summary of the invention

[0005] Based on the difference between the single-crop spray mode and the combined-crop spray mode, and the inconvenience of switching between the two spray modes, the present invention provides a multi-operation mode spray boom sprayer which can achieve rapid switching of spray boom modes by folding a hidden spray baffle.

[0006] The solution adopted by the present invention to solve the technical problem is: a multi-operation mode sprayer, including a body, a spray bar and a partition device, the spray bar is installed at the end of the body through a lifting mechanism, the spray bar is evenly equipped with spray heads, and the partition device is installed between adjacent spray heads.

[0007] The partition device includes a storage groove and a folding cloth. The folding cloth is folded and stored in the storage groove. A hanging plate is connected to the upper side of the folding cloth. The hanging plate can be made of a hard aluminum plate or an aluminum alloy plate. Perforations are provided at both ends of the storage groove. Wire holes corresponding to the perforations are provided on the hanging plate and the folding cloth. The storage rope passes through the perforations and the wire holes and is connected to the bottom layer of the folding cloth. One end of the hanging plate is installed on the top plate of the storage groove through a hollow sleeve. The hanging plate can rotate around the hollow sleeve. The interior of the hollow sleeve is hollow and its interior is connected to the wire hole.

[0008] A counterweight block is installed below the folded cloth corresponding to the movable end of the hanging plate, a slope is arranged on the storage slot below the counterweight block, and a slope with the same inclination direction as the slope is arranged at the other end of the storage slot, and the two slopes are arranged at intervals on the bottom surface of the inner cavity of the storage slot.

[0009] A storage system is also installed on the spray boom, which includes a motor and a set of parallel storage buses. Storage ropes are respectively inserted into the wire holes at both ends of the folding cloth, and the storage ropes are connected to the bottom layer of the folding cloth. The storage ropes at both ends of the folding cloth are respectively connected to the corresponding storage buses, and the storage buses are connected to the motor in a symmetrical manner.

[0010] The inclined surface at one end of the hollow casing is a spiral inclined surface.

[0011] A steering wheel, a controller, a seat, a medicine box, a diesel engine, a plunger pump, a generator and a hydraulic pump are fixed on the vehicle body in sequence from front to back. The vehicle body and the spray rod are connected by a lifting structure. The lifting mechanism includes a parallelogram lifting frame and a first hydraulic cylinder. The front end of the parallelogram lifting frame is fixed on the vehicle body, the front end of the first hydraulic cylinder is hinged to the lower part of the front end of the parallelogram lifting frame, and the rear end thereof is hinged to the upper part of the rear end of the parallelogram lifting frame. The spray rod is installed on the parallelogram lifting frame. There are two medicine boxes. The water inlet of the plunger pump is connected to the two medicine boxes respectively, and the water outlet thereof is connected to the nozzle on the spray rod through a hose.

[0012] The storage groove is a U-shaped structure, the storage groove is parallel to the spray rod and is located at the rear side of the spray rod, and the U-shaped storage groove opening faces the outside of the spray rod.

[0013] A torsion spring is installed between the storage slot and the hanging plate connected by a hollow sleeve, and the hanging plate is actively driven to rotate by the torsion spring. At the same time, a limiter is set on the top of the hollow sleeve end of the storage slot to control the rotation angle of the hanging plate. Under this structure, the storage slot can also adopt an inverted L-shaped structure.

[0014] Beneficial effects of the present invention:

[0015] The present invention provides a novel multi-operation mode spray boom sprayer, which realizes rapid switching of the spray boom modes by folding and hiding the spray baffle, thereby reducing the trouble of replacing the corresponding spray booms when switching between single-crop spraying and compound-cropping spraying, truly realizing the multi-purpose use of one machine, integrating the single-crop spraying and compound-planting spraying functions, improving the applicability of the operating machinery, and reducing the operating costs of agricultural production.

[0016] In single-crop spray mode, the folded cloth is stored in the storage slot. In compound-crop spray mode, the folded cloth is unfolded to separate the corresponding nozzles. The switching speed is fast. Only one set of spray boom system is needed to complete the switching of the two operation modes, which reduces the procurement cost and makes the switching of spray operation modes simpler and faster.

DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] Embodiment 1: In order to solve the problem of single-crop spraying and compound-crop spraying and avoid the situation where the spray rod needs to be replaced when the sprayer switches between single-crop spraying and compound-crop spraying, the present invention provides a novel multi-operation mode spray rod sprayer. By folding and hiding the spray baffle, the spray rod mode can be quickly switched, which reduces the trouble of replacing the corresponding spray rod when switching between single-crop spraying and compound-crop spraying. It truly realizes the multi-purpose of one machine, integrates the functions of single-crop spraying and compound-crop spraying, improves the applicability of operating machinery, and reduces the operating cost of agricultural production.

[0028] When single-crop spraying is performed, the spray baffle is folded and hidden, which is no different from the operating mode of a conventional sprayer. The operation can be performed in the same way as a conventional sprayer.

[0029] When using the composite planting spray bar module, since the current conventional strip composite planting method is to alternately plant four rows of soybeans and two rows of corn, the spray partition should be placed across the soybean belt for operation, and the soybean pesticide nozzle should be adjusted to completely cover the four rows of soybeans. However, for the corn belt, since it will be covered by the nozzle on the way back and forth, if the nozzle covers both rows of corn, the pesticide will be sprayed repeatedly, which not only increases the amount of pesticide used, but also causes irreversible effects on the corn plants in severe cases. Therefore, the position of the corn nozzle should be adjusted so that the nozzle covers only the row of corn close to the wheel position as much as possible. In this way, the plant protection vehicle turns around and enters the next row after completing one row, which just ensures that both rows of corn are sprayed with pesticide only once.

[0030] like Figure 1 As shown, the multi-operation mode sprayer provided by the present invention includes a common agricultural machinery operating body 1, a spraying boom 2 with a frame, and a partition device 3 installed on the spraying boom 2 at intervals, wherein the spraying boom 2 is installed at the end of the body 1, and the partition device 3 is installed between the nozzles on the spraying boom 2.

[0031] A steering wheel, a controller, a seat, a medicine box, a diesel engine, a plunger pump, a generator and a hydraulic pump are fixed to the vehicle body 1 in sequence from front to back. The vehicle body 1 and the spray rod 2 are connected by a lifting structure. The lifting mechanism includes a parallelogram lifting frame and a first hydraulic cylinder. The front end of the parallelogram lifting frame is fixed to the vehicle body 1, the front end of the first hydraulic cylinder is hinged to the lower part of the front end of the parallelogram lifting frame, and the rear end thereof is hinged to the upper part of the rear end of the parallelogram lifting frame. The spray rod 2 is installed on the parallelogram lifting frame. There are two medicine boxes. The water inlet of the plunger pump is connected to the two medicine boxes respectively, and the water outlet thereof is connected to the nozzle on the spray rod 2 through a hose.

[0032] A partition device 3 is installed between adjacent nozzles, such as Figure 2 and Figure 3 As shown, the partition device 3 includes a U-shaped storage groove 301 and a folded cloth 302 folded and stored therein. In order to facilitate unfolding, the folded cloth 302 needs to be made of flexible plastic or rubber, but the flexible folded cloth cannot support unfolding, so a hard hanging plate 308 is set on the upper side of the folded cloth 302, and the folded cloth is hung up by the hanging plate 308 for unfolding. At the same time, for lightness, the hanging plate 308 can be made of a hard aluminum plate or an aluminum alloy plate.

[0033] In the single-crop spray mode, the folded cloth 302 is stored in the storage slot. In the compound intercropping spray mode, the folded cloth 302 is unfolded in a fan shape to separate adjacent nozzles. Taking the compound intercropping of soybeans and corn as an example, two medicine boxes are connected to different nozzles, and the corresponding liquid medicine is respectively contained in the medicine boxes. Usually facing downward, the middle nozzle sprays soybeans, and the nozzles on both sides spray corn. During the spraying process, the fan-shaped folded cloth 302 unfolded between the nozzles separates the nozzles corresponding to soybeans and corn to prevent interference in the spraying of liquid medicine; when single-crop spraying, the two medicine boxes can be filled with the same liquid medicine, and the folded cloth can also be folded and stored, and a single liquid medicine will not cause mutual interference.

[0034] For the convenience of description, Figure 2-6 As shown, the two ends of the partition device 3 are respectively set as the A end and the B end. A perforation is set on the top plate of the storage groove 301 at the A end. When the folding cloth 302 is folded, an A end line hole 303 corresponding to the perforation is set on its cross section. An A end storage rope 304 is inserted into the A end line hole 303. The A end storage rope 304 is connected to the bottom layer of the folding cloth 302. At the same time, a counterweight block 305 is also connected to the bottom layer of the A end of the folding cloth. The counterweight block 305 pulls the folding cloth to fully unfold to form a partition.

[0035] An A-end inclined surface 310 is provided on the lower bottom surface of the A-end of the storage slot 301, and the inclined surface is inclined downward and faces the outside of the storage slot 301. The A-end storage rope 304 can be pulled up to pull up the A-end of the folding cloth, and the folding cloth is folded by utilizing the folding line of the folding cloth, so that it can be stored in the storage slot; when it needs to be unfolded, the A-end storage rope 304 is loosened, and the A-end of the folding cloth slides down along the inclined surface and slides out of the storage slot, and the counterweight pulls the folding cloth to unfold to form a fan-shaped partition.

[0036] The same perforation is set at the top of the B end of the storage slot, and the corresponding B end line hole 307 is set on the corresponding hanging plate 308 and the folded cloth below it. The hollow sleeve 306 is set in the perforation of the B end of the storage slot, and the lower hanging plate 308 is suspended on the lower side of the top plate of the storage slot through the hollow sleeve 306. The hanging plate 308 can rotate around the hollow sleeve 306. The B end storage rope 309 is inserted in the B end line hole 307. The B end storage rope 309 is connected to the bottom layer of the folded cloth at this end. The B end folded cloth can be loosened, tightened, turned and stored by pulling the B end storage rope 309.

[0037] The lower side of the storage groove at the B end is provided with a B end inclined surface, and the B end inclined surface is as shown in FIG. Figure 7 The figure shows a spiral inclined plane, along which the folded cloth can be rotated 90°, so that the folded cloth and the storage groove form a vertical structure.

[0038] like Figure 8As shown, a storage system is also installed on the spray rod 2, and the storage system includes a motor 4 and a group of parallel storage buses. Storage ropes are respectively inserted into the wire holes at both ends of the folding cloth 302, and the storage ropes are connected to the bottom layer of the folding cloth 302. The storage ropes at both ends of the folding cloth 302 are respectively connected to the corresponding storage buses, and the storage buses are connected to the motor 4 in a symmetrical manner.

[0039] A plurality of partition devices 3 are installed on the spray bar 2. The A-end storage rope 304 of each partition device 3 is connected to the corresponding A-end storage bus, and the B-end storage rope 309 is connected to the B-end storage bus. The motor winds up the bus to pull the A-end storage rope and the B-end storage rope, thereby driving the A-end storage rope and the B-end storage rope to reel in, and pulling the folding cloth to be folded and stored in the storage groove. When the motor releases the wire, the A-end of the folding cloth slides out of the storage groove along the inclined surface, and at the same time, the counterweight pulls the A-end of the folding cloth to unfold, and the B-end of the folding cloth slides along the spiral inclined surface, driving the folding cloth to rotate 90° to form a state perpendicular to the spray bar. The unfolded fan-shaped folding cloth forms a partition structure to separate the corresponding nozzles.

[0040] Example 2: In order to further ensure that the hanging plate 308 rotates 90° when the storage rope is relaxed, a torsion spring is installed between the storage slot 301 at the B end and the hanging plate 308. The torsion spring actively drives the hanging plate 308 to rotate, and a limit switch is set at the top of the B end of the storage slot to control the rotation angle of the hanging plate 308.

[0041] The storage and rotation of the hanging plate is achieved by pulling the storage rope at end A.

[0042] Embodiment 3: Based on Embodiment 2, the storage slot 301 adopts an inverted L-shaped structure, and a torsion spring is installed between the top plate and the hanging plate at the B end.

[0043] At the same time, the storage ropes at ends A and B are loosened. The hanging plate drives the folding cloth to rotate 90° as a whole under the action of the torsion spring. While rotating, both ends of the folding cloth fall down and unfold to form a partition. The structure is similar to that of a folding door.

[0044] When storing, the motor 4 reels the storage ropes at the A end and the B end at the same time, and the folded cloth is folded along its creases. At the same time, the A end is used to pull the hanging plate to overcome the force of the torsion spring and rotate for storage.

[0045] Embodiment 4: A transverse baffle is further installed on the spray bar 2, and the transverse baffle is installed above the nozzle. The upper transverse baffle is mainly used to reduce the airflow generated when the plant protection vehicle moves forward, thereby reducing the drift of droplets in the moving direction of the plant protection vehicle.

[0046] The above describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention to be protected.
