Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a three-way flat fertilizer spreader across an arch shed. Background Art

[0002] A directional fertilization device for corn planting with a publication number of "CN217241404U" in the prior art includes a silo, a partition is provided at the center of the inner cavity of the silo, a power silo is provided at the center of the bottom of the silo, and a bidirectional motor is provided at both the front and rear ends of the inner cavity of the power silo, a motor shaft is provided at the power output end of the bidirectional motor, a rotating rod is provided on the side of the motor shaft away from the bidirectional motor, and an adjustment mechanism is installed at the bottom of the rotating rod located at the bottom of the bidirectional motor. Through the coordinated use of the adjustment mechanism and its internal components, when in use, the position of the U-shaped mounting block can be driven to move horizontally on the outer surface of the adjusting screw rod by rotating the adjusting screw rod, thereby adjusting the distance between the moving wheels. Such operation can adjust the position of the moving wheel according to the width of the ridge, thereby facilitating the smooth movement of the equipment in the cornfield.

[0003] However, the above-mentioned device still has obvious defects during use: although the above-mentioned device can be moved within the field ridges, for the experimental field crops, some micro-arch sheds need to be installed on the field ridges. Once the arch sheds are installed, the fertilization process usually cannot be carried out under the operation of the fertilization mechanism. It is necessary to remove the film or manually lift the shed film for fertilization, and the fertilization process is relatively cumbersome. Therefore, for the field ridges with micro-arch sheds installed, the above-mentioned device cannot effectively fertilize. At the same time, the function of the above-mentioned device is relatively single and cannot meet the diverse needs when the arch shed is erected. Summary of the invention

[0004] The object of the present invention is to provide a three-way flat fertilizer spreader across an arch shed to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A cross-arch shed three-way flat fertilizer spreader, comprising a vehicle body, four traveling wheels are symmetrically mounted on the bottom of the vehicle body, the four traveling wheels are lifted and mounted on the vehicle body, a number of fertilizer ports that are equally spaced and linearly distributed are opened on the vehicle body, a fertilizer storage cabin is set above the fertilizer ports, a feed turntable is fixedly rotatably arranged between the fertilizer ports and the fertilizer storage cabin, a number of the feed turntables are fixedly connected to a driving shaft of a feed motor through a feed turntable shaft, the feed motor is fixedly mounted on the vehicle body, and during the movement of the vehicle body, the feed turntable is driven by the rotation of the feed motor to rotate, thereby transferring the fertilizer in the fertilizer storage cabin to the fertilizer port, and spreading it to the bottom of the vehicle body through the fertilizer port;

[0007] The traveling wheels lift the vehicle body upward so that it crosses several rows of arch sheds arranged in the field. The arch shed is composed of several frames and shed films. The frames are arranged in equidistant linear patterns. A fertilizer path is opened in the frame. The fertilizer path connects the inner and outer sides of the frame. The fertilizer port on the vehicle body is matched with the fertilizer path. At this time, the rotation of the unloading motor spreads the fertilizer to the inner side of the arch shed. A slideway is also opened on the side of the frame. Slide blocks are slidably installed on both sides of the slideway. The slide block is connected to the film edge of the shed film. The slide block is lifted and lowered and slid in the slideway to drive the two sides of the shed film to rise or fall, thereby making the shed film in a ventilated or heat-insulating state.

[0008] Preferably, the number of the rows of arch sheds is three, and the arch sheds are arranged along the left, middle and right directions of the vehicle body, and the traveling wheels are located on the traveling isolation belts between the rows of arch sheds.

[0009] Preferably, the four traveling wheels are all installed on the bottom of the vehicle body through a lifting frame, and the lifting frame is composed of a hydraulic telescopic cylinder and a connecting frame. The distance between the traveling wheel and the vehicle body is adjusted by lifting and lowering the hydraulic telescopic cylinder. The connecting frame is translationally slidably installed on the screw translation seat, and the translation screw installed in the screw translation seat is rotated to drive the connecting frames and traveling wheels on both sides to move closer or farther synchronously, thereby adjusting the spacing between the traveling wheels on both sides.

[0010] The traction rope on both sides is respectively wound in the parallel winding groove formed on the same winding roller, and the winding roller is rotatably mounted on the frame through a damping bearing. The winding roller is rotatably mounted on the frame through a damping bearing. The winding roller and the active driving turntable are rotatably mounted on the bottom of the car body. A winding and unwinding motor that drives the active driving turntable to rotate on the fixed axis is also installed on the car body. The active driving turntable is installed with an electromagnet. The active driving turntable magnetically cooperates with the winding roller when the electromagnet is energized. At this time, the rotation of the winding and unwinding motor synchronously drives the winding roller to rotate, and the winding or unwinding operation of the traction ropes on both sides is synchronously performed through the rotation of the winding roller. In the winding state, the traction rope overcomes the elastic force of the traction spring to do work, thereby pulling up and maintaining the greenhouse film along the two sides. At this time, the two sides of the greenhouse film are open and in a ventilation state.

[0011] Preferably, hollow channels are provided at the axis centers of the winding roller and the actively driven turntable, and the hollow channels on the winding roller and the actively driven turntable are respectively connected to the fertilization path and the fertilization port, and the fertilizer falling into the fertilization port enters the fertilization path through the actively driven turntable and the winding roller, and is spread from the fertilization path to the inside of the arch shed.

[0012] Preferably, the fertilization channel is in an inverted Y shape, and the fertilizer falling into the fertilization channel is spread along the left and right sides of the frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

At the same time, the two sides of the greenhouse film can be opened or closed. It has various functions, greatly reduces the workload of experimenters, and provides the best growth environment for the experimental crops in the greenhouse. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-6 , the present invention provides a technical solution:

[0024] Embodiment 1:

[0025] A cross-arch shed three-way flat fertilizer spreader, comprising a vehicle body 1, four traveling wheels 2 are symmetrically mounted on the bottom of the vehicle body 1, the four traveling wheels 2 are mounted on the vehicle body 1 in a lifting manner, a number of fertilizer ports 3 with equal spacing and linear distribution are opened on the vehicle body 1, a fertilizer storage cabin 4 is set above the fertilizer ports 3, a feed turntable 5 is fixedly arranged between the fertilizer ports 3 and the fertilizer storage cabin 4 for rotation, the feed turntables 5 are fixedly connected to the driving shaft of a feed motor 7 through a feed turntable shaft 6, the feed motor 7 is fixedly mounted on the vehicle body 1, and during the movement of the vehicle body 1, the feed turntable 5 is rotated by the rotation of the feed motor 7, so that the fertilizer in the fertilizer storage cabin 4 is transferred to the fertilizer port 3, and the fertilizer is spread to the bottom of the vehicle body 1 through the fertilizer port 3;

[0026] The traveling wheel 2 lifts the vehicle body 1 upward so that it crosses several rows of arch sheds 8 arranged in the field. The arch shed 8 is composed of several frames 9 and shed films 10. The frames 9 are arranged in an equidistant linear manner. A fertilizer path 11 is opened in the frame 9. The fertilizer path 11 connects the inner and outer sides of the frame 9. By cooperating with the fertilizer port 3 on the vehicle body 1 and the fertilizer path 11, the rotation of the unloading motor 7 spreads the fertilizer to the inner side of the arch shed 8. A slideway 12 is also opened on the side of the frame 9. Slide blocks 13 are slidably installed on both sides of the slideway 12. The slide blocks 13 are connected to the film edges of the shed film 10. The slide blocks 13 are lifted and lowered in the slideway 12 to drive the two sides of the shed film 10 to rise or fall, thereby making the shed film 10 in a ventilated or heat-insulating state.

[0027] The hopper 1 is provided with a plurality of wheels 2, each of which is provided with a plurality of movable parts and components, and the plurality of movable parts and components are provided with a plurality of movable parts and components. Fertilizer is spread into the fertilizer channel 11, so that the fertilizer falls from the fertilizer channel 11 onto the soil inside the arch shed 8, thereby completing the fertilization operation. The fertilizer channel 11 is inverted Y-shape, and the fertilizer falling into the fertilizer channel 11 is spread along the left and right sides of the frame, thereby preventing the fertilizer from being too concentrated. The arch shed 8 needs to perform film lifting and film covering operations at different temperatures, so that the temperature inside the arch shed 8 is too high or too low. Therefore, the prior art mostly uses manual film lifting and film covering operations. In this embodiment, a slide 12 is provided on the frame 9, and a slider 13 provided in the slide 12 is used to connect the corners of the greenhouse film 10. During the lifting and lowering process of the slider 13, the greenhouse film 10 is driven to be lifted or fallen, thereby completing an autonomous and controllable film covering operation, which greatly reduces the workload of the experimenter. In the later stage, the structure can be further optimized and the fertilizer spreader can be connected to the temperature and humidity sensor to work autonomously, thereby greatly ensuring the best growth environment for crops in the arch shed 8.

[0028] Embodiment 2:

[0029] The number of the rows of arch sheds 8 is three, and the arch sheds 8 are arranged along the left, middle and right directions of the vehicle body 1 , and the traveling wheels 2 are located on the traveling isolation belts 14 between the rows of the arch sheds 8 .

[0030] The four traveling wheels 2 are all installed at the bottom of the vehicle body 1 through a lifting frame. The lifting frame is composed of a hydraulic telescopic cylinder 15 and a connecting frame 16. The distance between the traveling wheel 2 and the vehicle body 1 is adjusted by lifting and lowering the hydraulic telescopic cylinder 15. The connecting frame 16 is installed on a screw translation seat 17 in a translational and sliding manner. The translation screw installed in the screw translation seat 17 rotates, driving the connecting frames 16 and the traveling wheels 2 on both sides to move toward or away from each other synchronously, thereby adjusting the distance between the traveling wheels 2 on both sides.

[0031] In this embodiment, the number of arch sheds 8 is further disclosed. By arranging three rows of arch sheds 8, the vehicle body 1 can perform fertilization operations on three ridges simultaneously during the moving process, which greatly improves the fertilization efficiency, and the traveling wheels 2 can translate and slide to adjust the wheelbase thereof. The significance of this arrangement is that fertilization operations can be performed in ridges with different row spacings.

[0032] Embodiment three:

[0033] A traction spring 18 is installed at the bottom of the slide 12 to pull the slider 13 downward without external force. A traction rope 19 is installed on the side of the slider 13 away from the traction spring 18. The traction ropes 19 on both sides are respectively wound in parallel winding grooves 21 opened by the same winding roller 20. The winding roller 20 is fixedly rotatably installed on the frame 9 through a damping bearing 22. The winding roller 20 is movably matched with an active drive turntable 23, and the active drive turntable 23 is fixedly rotatably installed at the bottom of the vehicle body 1. The vehicle body 1 is also equipped with a driving active drive turntable. The unwinding and winding motor 23 is capable of rotating on a fixed axis, and an electromagnet is installed in the active driving turntable 23. The active driving turntable 23 magnetically cooperates with the winding roller 20 when the electromagnet is energized. At this time, the rotation of the unwinding and winding motor 24 synchronously drives the winding roller 20 to rotate, and the winding or unwinding operation of the traction ropes 19 on both sides is synchronously performed through the rotation of the winding roller 20. In the winding state, the traction ropes 19 overcome the elastic force of the traction springs 18 to do work, thereby pulling up and holding the greenhouse film 10 along both sides. At this time, both sides of the greenhouse film 10 are open and in a ventilated state.

[0034] In this embodiment, a structure for driving the greenhouse film 10 to be lifted or closed is further disclosed. The winding and unwinding operations of the traction rope 19 are performed by the rotation of the winding roller 20. During the winding and unwinding process of the traction rope 19, the traction slider 13 slides in the slideway 12. Since the slider 13 is connected to the bottom edge positions of both sides of the greenhouse film 10, the lifting and lowering of the slider 13 drives the greenhouse film 10 to be lifted or closed. The winding roller 20 rotates synchronously with the rotation of the active driving turntable 23. The active driving turntable 23 rotates through the inner The electromagnet in the upper part is energized and electrically connected to the winding roller 20, thereby completing the adsorption and cooperation operation. When the active driving turntable 23 moves under the rotation of the winding and unwinding motor 24, the winding roller 20 is synchronously driven to work. Since the winding roller 20 is installed on the frame 9 through the damping bearing 22, the damping bearing 22 can enable the winding roller 20 to overcome the downward elastic force of the traction spring 18 and limit the position, so that it can also remain stationary after the active driving turntable 23 is moved away, thereby enabling the greenhouse film 10 to be stably in the lifted state.

[0035] Embodiment 4:

[0036] A hollow channel 25 is provided at the axis of the winding roller 20 and the actively driven turntable 23. The hollow channels 25 on the winding roller 20 and the actively driven turntable 23 are respectively connected to the fertilization path 11 and the fertilization port 3. The fertilizer falling into the fertilization port 3 enters the fertilization path 11 through the actively driven turntable 23 and the winding roller 20, and is spread from the fertilization path 11 to the inside of the arch shed 8.

[0037] In this embodiment, the hollow structure of the winding roller 20 and the active drive turntable 23 is further disclosed, so that the two can complete fertilization and material feeding, and can also adjust the lifting and lowering of the greenhouse film 10 during the cooperation process. The advantage of this design is that fertilization and adjustment of the greenhouse film 10 can be achieved using a set of mechanisms, which improves the coordination efficiency and accuracy between the structures and ensures that the device can work normally. Furthermore, a liquid fertilizer application mechanism and a vibration mechanism can be added to the vehicle body 1 to ensure that the fertilizer can be smoothly spread on the ground through the fertilization channel 11. At the same time, the liquid fertilizer application mechanism can spray fertilization on the ground when the arch shed 8 is open.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
