Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment, and in particular to an adjustment mechanism for the boom frame of a self-propelled boom sprayer. Background Technology

[0002] Self-propelled boom sprayers are widely used pesticide application equipment in agriculture. Their main function is to evenly spray pesticides, fertilizers, or other liquid substances onto the leaves and soil surface of crops through a spraying device, thereby protecting crops and increasing crop yields. To adapt to different crops, field environments, and operational requirements, the design of sprayers needs to be flexible and adjustable.

[0003] The spray boom mount, as a crucial component of the sprayer, directly impacts its operational efficiency and spray quality. Its function is to support the spray boom and nozzles, ensuring even application of pesticides during operation.

[0004] However, traditional spray booms are generally quite long to be suitable for spraying large areas of crops, and they require manual folding for storage, which is quite troublesome. Furthermore, the direction of the nozzles cannot be changed according to the needs of different crops (e.g., some crops require pesticides to be sprayed on the leaves, while others require pesticides to be sprayed on the roots and stems), which leads to poor spraying quality.

[0005] Meanwhile, during the folding and storage process, the tail end of the traditional spray boom holder moves very quickly. Due to inertia, if the tail end of the spray boom holder collides with the sprayer or other relatively hard objects, it is prone to damage, affecting subsequent use.

[0006] To address this issue, a boom adjustment mechanism for a self-propelled boom sprayer is proposed. Utility Model Content

The right end of the electric push rod 214 is hinged to the connecting seat 215. The positioning component 220 includes a rotating shaft 226. The rear surface of the rotating shaft 226 is fixedly connected to the spray rod 3. The outer wall of the spray rod 3 is provided with a protective component 4, which can provide protection for the tail end of the spray rod 3. The left surface of the spray rod 3 is penetrated and fixedly connected to a connecting pipe 5. The connecting pipe 5 can be connected to one end of an external hose. The other end of the hose is installed on the sprayer for delivering pesticides. The left surface of the spray rod 3 is equipped with a nozzle 6. There are multiple nozzles 6, which are evenly distributed on the left surface of the spray rod 3. The adjustment mechanism 2, the protective component 4, the connecting pipe 5 and the nozzles 6 are provided in two sets, which are symmetrically distributed on the left and right sides of the center line of the mounting frame 1.

[0035] Reference Figure 1 - Figure 3The positioning component 220 also includes a pull rod 221, which consists of two parts: the right end is in the shape of a pull ring and the left end is in the shape of a round rod. The inner wall of the connecting rod 211 is elastically connected to a locking block 223 by a compression spring 222. The inner wall of the locking block 223 is elastically connected to a positioning block 225 by a connecting spring 224. The outer wall of the rotating shaft 226 is provided with a slot 227, and the locking block 223 and the slot 227 fit together.

[0036] Reference Figure 1 , Figure 4 The protective component 4 includes a sleeve 411. One end of a positioning spring 412 is fixedly connected to the inner wall of the bottom end of the sleeve 411. The other end of the positioning spring 412 is fixedly connected to a slide rod 413. A protective plate 414 is fixedly connected to the upper surface of the slide rod 413. The protective component 4 is provided in four sets, which are evenly distributed on the four surfaces of the spray bar 3.

[0037] Reference Figure 1 - Figure 3 The connecting rod 211 is hinged to the right end of the mounting bracket 1, the right surface of the connecting seat 215 is fixedly connected to the left surface of the connecting rod 211, and the rotating shaft 226 passes through and is rotatably connected to the rear surface of the connecting rod 211.

[0038] Reference Figure 1 - Figure 3 Pull rod 221 is slidably connected to the right surface of connecting rod 211 and moves laterally. The left surface of pull rod 221 is fixedly connected to the right surface of locking block 223. When pull rod 221 is pulled, locking block 223 moves synchronously. One end of compression spring 222 is fixedly connected to the right surface of locking block 223, and the other end of compression spring 222 is fixedly connected to the inner wall on the right side of connecting rod 211. Locking block 223 is slidably connected to the inner wall of connecting rod 211. When locking block 223 moves to the right, it squeezes compression spring 222 to generate a reaction force. One end of connecting spring 224 is fixed. The other end of the connecting spring 224 is fixedly connected to the inner wall of the right side of the locking block 223. The positioning block 225 is slidably connected to the left surface of the locking block 223. When the positioning block 225 moves to the right, it will squeeze the connecting spring 224 to generate a reaction force. The left end of the positioning block 225 is set as an arc surface. When the arc surface of the positioning block 225 is squeezed, the positioning block 225 will move to the right. The positioning block 225 is inserted into the inner wall of the slot 227. The locking block 223 is inserted into the inner wall of the slot 227. When the locking block 223 moves to the right, it will disengage from the slot 227 and release the limit.

[0039] Reference Figure 1 , Figure 4 The slide rod 413 passes through and is slidably connected to the upper surface of the sleeve 411. The protective plate 414 is set in an arc shape. When the protective plate 414 is squeezed, the slide rod 413 will move downward to squeeze the positioning spring 412 and generate a reaction force.

[0040] Working principle: When using this device, first install one end of the pesticide delivery hose on the connecting pipe 5, then start the electric push rod 214 to extend it, which in turn squeezes the connecting seat 215 to drive the connecting rod 211 to rotate and unfold. Then adjust the orientation of the nozzle 6 as needed.

[0041] First, pull the lever 221 to move the locking block 223. The moving locking block 223 will disengage from the slot 227, releasing the restriction on the rotating shaft 226, and will squeeze the compression spring 222 to generate a reaction force. After the restriction on the slot 227 is released, rotate the spray rod 3 to drive the rotating shaft 226 and the nozzle 6 to rotate, thereby realizing the adjustment of the nozzle 6 angle.

[0042] When the rotating shaft 226 rotates, it will press the arc surface of the positioning block 225. The positioning block 225 will be pressed and retract into the locking block 223 to release the obstruction. It will also press the connecting spring 224 to generate a reaction force. When the positioning block 225 is aligned with another locking slot 227, it will be pushed by the connecting spring 224 and inserted into the locking slot 227. People can feel the difference in force at this time, thus achieving the alignment effect. When the locking block 223 is aligned with the properly positioned locking slot 227, the pull rod 221 is released. The reaction force of the compression spring 222 will push the locking block 223 and the locking slot 227 to insert and limit the spray bar 3 and the nozzle 6, ensuring the stability of the nozzle 6 orientation. At this time, the device can be used normally to spray pesticides.

[0043] During use, if a collision occurs when the tail end of the spray bar 3 rotates, the foreign object will first come into contact with the protective plate 414. The protective plate 414 will drive the slide bar 413 to retract and squeeze the positioning spring 412 to generate a reaction force. Under the influence of the retraction of the protective plate 414 and the slide bar 413 and the reaction force of the positioning spring 412, the impact can be effectively reduced and the spray bar 3 can be protected.

[0044] When finished using the product, activate the electric push rod 214 to retract, which will cause the spray bar 3 to rotate in the opposite direction for storage.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
