Description

TECHNICAL FIELD

[0002] In recent years, the strip-division planting mode of soybean and corn has been widely promoted. This mode can take advantage of the high-position crop edge row and expand the low-position crop light space by adopting the wide-narrow row field arrangement, so as to realize the harmonious coexistence of soybean and corn in the same plot and one-season double harvest, and has the advantages of significant yield increase and fertilizer saving.

[0003] Full-mechanical technology is an important guarantee for the large-area promotion of the strip-division planting mode of soybean and corn, and field plant protection machinery is an important part of it. The strip-division planting mode of soybean and corn is generally 2:4 or 2:5, that is, 2 rows of corn adjacent to 4 rows of soybean or 2 rows of corn adjacent to 5 rows of soybean. Since soybean and corn belong to different families, the herbicides used for weeding after seedling are different, and the mixed use of herbicides will cause serious problems. Therefore, soybean and corn need to be sprayed separately.

[0004] In view of the agricultural requirement that the strip-division planting of soybean and corn needs to be sprayed separately, the patent CN112753677A, CN115428780B and CN112616802A design a strip-division spraying boom sprayer suitable for the strip-division planting of soybean and corn. By adding an anti-interference plate in the soybean spraying boom and the corn spraying boom, the spraying strips of soybean and corn can be blocked from cross-spraying by the anti-interference plate during spraying. However, due to strong wind, drift of droplets and other reasons, some herbicides still drift above the anti-interference plate to the adjacent spraying strip, causing pesticide damage and affecting crops.

The cover assembly includes a front flexible cover 1, a rear flexible cover 2, and a side flexible cover 7. The tops of the front and rear flexible covers are fixedly mounted on the spray bar, and the bottoms are respectively provided with flexible cover support rods 8. In this embodiment, the material of each cover in the cover assembly is waterproof plastic cloth. In actual applications, other waterproof flexible fabrics can also be used. In this way, the front and rear flexible covers can be rolled up to the spray bar using the flexible cover support rods as pivots, and fixed to the spray bar by cable ties or buckles, so that the front and rear flexible covers can be stored when spraying is not required.

[0035] The side flexible shell 7 is triangular in shape and located between the front and rear flexible shells. The two inclined sides of the side flexible shell are respectively fixedly connected to the support rods on the folding mechanism. When the support rods 11 on the folding mechanism are unfolded or folded, the side flexible shell can be unfolded and folded at the same time. Furthermore, the side flexible shell is symmetrically provided with buckles 9 by bolts near the bottom of the inclined sides. When the folding mechanism is unfolded, the two support rods of the folding mechanism are respectively locked into the buckles for fixation, thereby providing a certain support for the front and rear flexible shells. When the folding mechanism is in the folded state, the two support rods are removed from the buckles, thereby facilitating the folding of the support rods.

[0036] like Figures 3-7 As shown, the folding mechanism includes movable sleeve 1 39, movable sleeve 2 40, support rod 11, connecting rod 19, support rod fixing part 13, connecting rod fixing part 18, and rotating collar 12. Movable sleeve 1 includes upper fixing buckle I 15 and lower fixing buckle I 14, and movable sleeve 2 includes upper fixing buckle II 16 and lower fixing buckle II 17. The upper fixing buckle and lower fixing buckle on the two movable sleeves are respectively provided with arc-shaped inner cavities. The arc-shaped inner cavities of the two sleeves are matched and connected together and fitted with the spray bar by bolts.

[0037] The top of the upper fixed ring I and the upper fixed ring II further extends upwardly a connecting portion, the left and right sides of the connecting portion are respectively provided with a connecting hole 42, the connecting hole is used for cooperating with the driving mechanism and the return mechanism. The left and right oblique lower sides of the bottom of the lower fixed buckle I and the lower fixed buckle II are respectively provided with a U-shaped groove 41, the opening ends of the two grooves are oppositely arranged, further, the two grooves of the lower fixed buckle I are respectively rotatably connected with a support rod fixing piece 13 through a cylindrical pin 36, and the bottom of the support rod fixing piece is fixedly installed with a support rod 11, so that the support rod can freely rotate around the cylindrical pin, and the rotation range is 90 degrees.

[0038] In the two grooves of the lower fixed buckle II, a connecting rod fixing piece 18 is rotatably connected through a cylindrical pin 36, and the bottom of the connecting rod fixing piece 18 is fixedly installed with a connecting rod 19. The end of the connecting rod is hingedly connected with a rotating sleeve ring through a support rod fixing piece, and the rotating sleeve ring is matched and sleeved on the support rod 11, that is, the two ends of the connecting rod are respectively fixedly connected with the connecting rod fixing piece 18, and the connecting rod and the connecting rod fixing piece can freely rotate around the cylindrical pin 36 in the U-shaped groove, and the angle rotation range is 90 degrees. The rotating sleeve ring 12 is provided with a mounting groove, and the cylindrical pin in the mounting groove is hingedly connected with the connecting rod fixing piece. In this way, the connecting rod fixing piece can freely rotate around the cylindrical pin in the mounting groove of the rotating sleeve ring. During operation, the movable sleeve one is fixedly installed at the left and right ends of the spray rod, and the movable sleeve two is sleeved on the spray rod. By moving the movable sleeve two left and right, the rotation of the connecting rod and the support rod can be driven, so that the unfolding and folding of the folding mechanism are realized.

[0039] As shown in Figure 4 and Figure 5 , the return mechanism includes a return spring 30, a spring upper mounting bracket 29 and a spring lower mounting bracket 31. The spring upper mounting bracket and the spring lower mounting bracket are sleeved on the spray rod through a bolt, the spring upper mounting bracket is provided with a hanging hole, one end of the return spring is hung in the hanging hole at the top of the spring upper mounting bracket, and the other end is hung in the connecting hole 42 at the top of the upper fixed buckle II. The return mechanism is used for cooperating with the folding mechanism. When the folding mechanism is in the unfolded state, the movable sleeve two slides towards the movable sleeve one, and the return spring is stretched. When the folding mechanism returns to the folded state, the return spring is contracted, and the movable sleeve two is moved away from the movable sleeve one under the action of the spring, so that the support rod of the folding mechanism is contracted.

[0040] As shown in Figure 3 , Figure 8 and Figure 9As shown, the driving mechanism comprises a pulley set 20, a traction line 21, a stepper motor controller 22, a stepper motor 23, a winding wheel 24, wherein the stepper motor 23 is fixedly installed on the rack through a motor mounting frame 25, a winding wheel 24 is sleeved on the output shaft of the stepper motor, and is locked through a bolt, the winding wheel is provided with two winding grooves for respectively cooperating with the folding mechanisms at the left and right ends of the spray rod through the traction line; the stepper motor controller is fixedly installed on the rack through a bolt, and is used for controlling the forward rotation and reverse rotation of the stepper motor.

[0041] As shown in Figure 3 and Figure 9 As shown, the pulley set 20 is also fixedly installed on the left and right ends of the spray rod through a bolt, the pulley set comprises a pulley 33, a pulley bracket 32, a pulley shaft 35 and a wire harness auxiliary mechanism 34, the pulley shaft is fixed on the pulley bracket through a nut, the pulley 33 is matched and sleeved on the pulley shaft 35, a threaded hole is formed in the top end of the other end of the pulley shaft, and the wire harness auxiliary mechanism is fixed on the top end of the pulley shaft through a bolt, and the pulley freely rotates around the pulley shaft.

[0042] One end of the traction line 21 is wound on the winding wheel, the other end passes through the pulley at the end of the spray rod, changes direction, and is fixedly connected with the connecting hole at the top of the upper fixed buckle II after being guided through the intermediate wire harness auxiliary mechanism 34; when the stepper motor 23 rotates, the traction line 21 is wound on the winding wheel 24, changes direction through the pulley 33, and finally drives the upper fixed buckle II 16 to move left and right along the spray rod 3.

[0043] As shown in Figure 4 As shown, the proximity switch 26 is also fixedly installed on the spray rod between the movable sleeve I and the movable sleeve II, the proximity switch is fixed on the mounting rack, the mounting rack comprises an upper mounting rack 27 and a lower mounting rack 28, the proximity switch is fixed on the top of the upper mounting rack through a bolt, and the upper mounting rack 27 and the lower mounting rack 28 are fixedly installed on the spray rod through a bolt, when the upper fixed buckle II slides on the spray rod and touches the proximity switch, the proximity switch sends a signal, and the stepper motor controller controls the stepper motor to stop after obtaining the signal; the stepper motor drives the left and right two folding mechanisms to move after being guided by the pulleys at the two ends of the spray rod; when unfolding operation is performed, the stepper motor rotates forward, drives the upper fixed buckle II to move in the direction close to the upper fixed buckle I through the traction line, and the supporting rod of the folding mechanism is unfolded.

[0044] The foldable split spray rod sprayer anti-drift cover shell provided by the application has two working states of unfolding and folding in actual application, and specifically comprises:

[0045] (1) The cover is in the unfolded state: the stepper motor is driven to rotate forward by the stepper motor controller, which drives the winding wheel to rotate and wind the traction line around the winding wheel. At the same time, the other end of the traction line drives the movable sleeve II to move closer to the movable sleeve I and drives the return spring to stretch. At the same time, the connecting rod at the bottom of the lower fixed buckle rotates, which drives the support rod and the lateral flexible cover on the support rod to unfold. When the upper fixed buckle II moves to touch the proximity switch, the stepper motor controller detects the level signal of the proximity switch and controls the stepper motor to stop rotating. The two support rods are respectively locked into the buckles to support the front flexible shell and the rear flexible shell. Thus, the lateral flexible covers on both sides together with the front flexible shell and the rear flexible shell form a fully enclosed anti-drift cover except for the bottom.

[0046] (2) The cover is in a folded state: First, each support rod needs to be removed from the buckle, and the stepper motor is controlled to rotate in the opposite direction by the stepper motor controller. At the same time, the winding wheel is rotated and the traction line is restored to the initial state. Since the return spring is in a stretched state during the unfolding process, under the contraction of the return spring, the movable sleeve 2 moves away from the movable sleeve 1 along the spray bar. At the same time, the connecting rod at the bottom of the lower fixed buckle rotates in the opposite direction, which drives the support rod and the lateral flexible cover on the support rod to be folded. After the support rod of the folding mechanism is retracted, the flexible shell support rods at the bottom of the front flexible shell and the rear flexible shell are respectively used as the central axis. The front flexible shell and the rear flexible shell are rolled up around their central axis and fixed to the spray bar by tools such as cable ties. The folding of the anti-drift cover can be realized.

[0047] The fully enclosed anti-drift cover provided by this invention can reduce the drift of pesticide droplets during spraying, and can automatically unfold and fold through a driving folding mechanism, improving the level of intelligence and work efficiency; and effectively prevents droplet drift in the forward direction and above, reducing the cross-spraying of herbicides.

[0048] The above description is only a preferred embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
