Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, specifically a spraying device for agricultural machinery. Background Technology

[0002] Agricultural machinery includes rotary tillers, graders, seeders, and irrigation machines, among which rotary tillers include L-shaped tillage blades (such as...). Figure 5 (as shown) and disc plow (as shown) Figure 6 As shown, both the tillage blade and the disc plow have multiple positioning holes. When processing these two components, anti-corrosion paint needs to be sprayed onto their surfaces. Currently, the painting of these two components is either done manually, which is inefficient, or fixed using two different positioning fixtures. It is impossible to fix two components of different shapes using the same positioning fixture, resulting in low compatibility. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a spraying device for agricultural machinery, thereby solving the problem of low adaptability of current agricultural machinery spraying devices.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A spraying device for agricultural machinery includes a housing with a spray box open at the front. A displacement mechanism is installed in the upper part of the spray box, and a lifting cylinder is mounted on the displacement mechanism. The displacement mechanism drives the lifting cylinder to move left and right and back and forth within the spray box. The lower end of the lifting cylinder is connected to a spraying mechanism. A paint feeding mechanism is provided inside the housing to supply paint to the spraying mechanism. A positioning mechanism is installed inside the spray box on the housing. The positioning mechanism includes a cover fixed to the top of the housing, a partition fixed in the middle of the cover, and openings on both sides of the partition at the top of the cover.

[0007] Using the above technical solution, starting the first motor drives the first lead screw to rotate, which in turn drives the first slide to move left and right along the first guide rod. Starting the second motor drives the second lead screw to rotate, which in turn drives the second slide to move back and forth along the second guide rod.

[0008] Preferably, the spraying mechanism includes a housing connected to the telescopic end of the lifting cylinder, a spray pipe connected to the bottom of the housing, a nozzle installed at the lower end of the spray pipe, and a distance sensor also installed at the bottom of the housing.

[0009] Through the above technical solution, the pump operates, and through the cooperation of the paint delivery pipe and hose, the anti-corrosion paint in the paint storage tank is delivered to the spray pipe and sprayed out by the nozzle, thus realizing the painting. The distance sensor can sense the distance between the nozzle and the part to be painted, thereby controlling the operation of the lifting cylinder to ensure that the distance between the nozzle and the part to be painted reaches the set value.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1-4A spraying device for agricultural machinery includes a housing 1, on which a spraying box 2 with a front opening is mounted. A displacement mechanism 3 is mounted on the upper part of the spraying box 2, and a lifting cylinder 4 is mounted on the displacement mechanism 3. The displacement mechanism 3 drives the lifting cylinder 4 to move left and right and back and forth within the spraying box 2. Specifically, the displacement mechanism 3 includes first bearing seats 301 fixed to both sides of the upper part of the spraying box. A first lead screw 302 is rotatably connected to the two first bearing seats 301 via a rotary bearing. A first guide rod 303 is also fixed to the two first bearing seats 301. A first motor 304 is mounted on the outside of the spraying box 2. The first motor 304 is connected to one end of the first lead screw 302 via a coupling. A first slide block 305 is threaded onto the first lead screw 302, and the first slide block 305 slides against the first guide rod 303. The first slide block 305 is connected to a second bearing housing 306 at both ends of its bottom surface. A second lead screw is rotatably connected to each of the two second bearing housings 306 via a rotary bearing. A second guide rod is also fixed to each of the two second bearing housings. A second motor 307 is mounted on the front side of the first slide block. The second motor 307 is connected to one end of the second lead screw via a coupling. A second slide block 308 is threaded onto the second lead screw and slidably connected to the second guide rod. A lifting cylinder 4 is mounted on the bottom surface of the second slide block 308. Controlling the first motor 304 to rotate the first lead screw 302 causes the first slide block 305 to move left and right along the first guide rod 303. Starting the second motor 307 rotates the second lead screw, causing the second slide block 308 to move back and forth along the second guide rod, thus moving the lifting cylinder 4 in both left-right and back-and-forth directions.

[0027] The lower end of the lifting cylinder 4 is connected to a spraying mechanism 5. A paint feeding mechanism 6 is installed inside the housing 1, which supplies paint to the spraying mechanism 5. A positioning mechanism 7 is installed inside the spraying box 2 on the housing 1 to fix the agricultural machinery parts to be sprayed. Specifically, the spraying mechanism 5 includes a box 501 connected to the telescopic end of the lifting cylinder 4. A spray pipe 502 is connected to the bottom of the box 501, and a nozzle is installed at the lower end of the spray pipe 502. A distance sensor 503 is also installed at the bottom of the box 501. The paint delivery mechanism 6 includes a paint storage tank 601 located on one side of the machine casing. A paint injection pipe is connected to the upper part of the tank for adding paint. A pump body 602 is installed outside the machine casing 1. The inlet end of the pump body 602 is connected to the paint storage tank 601 via a pipe, and the outlet end of the pump body 602 is connected to a paint delivery pipe 603. A flexible hose 604 is connected to the paint delivery pipe 603, with one end of the hose 604 entering the housing 501 and connecting to the spray nozzle 502. A control valve is also installed on the paint delivery pipe to control its opening and closing. By controlling the pump body 602, the anti-corrosion paint in the paint storage tank 601 is delivered to the spray nozzle 502 through the cooperation of the paint delivery pipe 603 and the hose 604, and then sprayed out through the nozzle, thus achieving paint spraying. A distance sensor is an electronic device used to measure the distance between an object and a sensor, and is widely used in robotics, autonomous driving, industrial automation, smart homes, and other fields. In this embodiment, the distance sensor 503 is an infrared sensor. It calculates the distance by utilizing the reflection intensity or phase change of infrared light. Infrared sensors are existing technology, and their principle will not be described in detail here. The distance sensor can sense the distance between the nozzle and the part to be sprayed and transmit the signal to the controller. The controller then controls the lifting cylinder to work so that the distance between the nozzle and the part to be sprayed reaches the set value.

[0028] In addition, a level gauge can be installed inside the paint storage tank to measure the paint level and allow for timely replenishment. A stirring mechanism can also be installed inside the tank to ensure more even paint application.

[0029] The positioning mechanism 7 includes a cover 701 fixed to the top of the chassis. A partition 702 is fixed in the middle of the cover 701. The top of the cover 701 has strip-shaped sliding holes 703 on both sides of the partition 702. Sliding rods 704 are slidably connected within the two sliding holes 703. The width of the sliding holes 703 is slightly smaller than the width of the sliding rods 704 so that the sliding rods 704 can slide smoothly within the sliding holes 703 without significant wobbling. Sliding blocks 705 are fixed to the lower ends of the two sliding rods 704. First screws 7 are rotatably connected to both sides of the partition 702 via rotary bearings. 06. The ends of the two first screws 706 away from the partition are rotatably connected to the inner wall of the cover 701 through a rotary bearing. The two sliders 705 are threadedly connected to the two first screws 706 respectively. The ends of the two first screws 706 away from the partition pass through the cover 701, and the passing ends are fixedly connected to handles 707. The upper ends of the two slide rods 704 are rotatably connected to Z-shaped rods 708 through rotary bearings. The top of the Z-shaped rods 708 is provided with mounting holes, and the mounting holes are threadedly connected to second screws 709. Two nuts 710 are threadedly connected to the second screws 709. When fixing agricultural machinery parts, first remove a nut 710 from the second screw 709. Then, turn the handle 707 to rotate the first screw 706. When the first screw 706 rotates, it causes the corresponding sliding rod 704 to slide within the sliding hole 703, thereby adjusting the position of the sliding rod 704. By rotating the handles 707 at both ends, the distance between the two sliding rods 707 can be adjusted. By rotating the Z-shaped rod 708, the position of the two second screws 709 can be further adjusted so that the two second screws 709 are aligned with the positioning holes on the corresponding parts. Alternatively, the appropriate model of second screw 709 can be selected according to the diameter of the positioning holes on different parts, and the second screw 709 can be installed on the Z-shaped rod so that the second screw 709 can be inserted into the positioning holes of the corresponding parts, further improving the adaptability of agricultural machinery parts.

[0030] The front opening of the spray booth 2 is hinged with a transparent door 9, and the first door panel is magnetically locked to the opening of the spray booth. Sealing strips are provided around the inside of the door; when the door is closed, the sealing strips adhere tightly to the edge of the spray booth opening to prevent paint leakage.

[0031] A controller 10 is located on the side of the housing 1 away from the paint storage tank 601. The first motor 304, the second motor 307, the pump body 602, the distance sensor 503, and the lifting cylinder 4 are all electrically connected to the controller 10. The controller contains a control program for controlling the operation of the first motor, the second motor, the pump body, and the lifting cylinder. A power button should also be provided on the housing for starting the equipment.

[0032] The working principle of this embodiment is as follows:

[0033] The tillage blade 11 or disc plow 12 is fixed on the positioning fixture 7. Specifically, first, remove one nut 710 from the second screw 709. Based on the diameter of the positioning holes on the tillage blade 11 or disc plow 12, select a suitable second screw 709 and install it on the Z-shaped rod 708. Then, adjust the distance between the two sliding rods 704 according to the position and spacing of the positioning holes on the tillage blade 11 or disc plow 12, and rotate the Z-shaped rod to align the two second screws 709 with the positioning holes on the corresponding accessories. Next, install the corresponding accessories on the second screws 709. Finally, install the removed nut 710 back onto the second screws. The accessories are then fixed to the second screws 709 using the two nuts 710, thus achieving the fixation of the corresponding accessories. Clamping the accessories with nuts reduces the clamping area, thereby facilitating full-body spraying of the accessories.

[0034] Then, the first motor 304 is started, driving the first slide 305 to move from left to right. At the same time, the second motor 307 is started, driving the second slide 308 to move from front to back. This causes the spraying mechanism 5 to move in the left-right and front-back directions to spray the top surface of the accessory in all directions. After one side is sprayed, the accessory is removed, flipped over, and fixed to the second screw. The other side is then sprayed using the same method until the spraying is complete.

[0035] Example 2

[0036] Based on Embodiment 1, an exhaust pipe 8 is connected to the upper end of the spray box 2. The exhaust pipe is connected to an external exhaust fan, which extracts the paint mist from the spray box and sends it to the air handling unit.
