Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural sprayer processing, more particularly, it relates to a processing method of an agricultural sprayer. BACKGROUND

[0002] Plant protection is an important part of agricultural and forestry production, and is one of the important measures to ensure the high yield and high harvest of agriculture and forestry. In order to economically and effectively carry out plant protection, various control methods and active roles should be played, and the principle of "prevention first and comprehensive prevention and control" should be implemented to eliminate diseases, pests, weeds and other harmful organisms before they cause disaster, which requires spraying pesticides on plants.

[0003] Therefore, the agricultural sprayer becomes an important tool for plant protection. The traditional agricultural sprayer includes a liquid storage chamber and a driving chamber. As the main functional chamber, the driving chamber needs to ensure that the agricultural sprayer body still has strong structural strength after injection molding. For example, only a plastic layer is provided between the driving chamber and the liquid storage chamber. During transportation or use, the middle layer is easily broken due to extrusion, thereby affecting the service life of the agricultural sprayer. Therefore, how to improve the structural strength of the middle layer is a major problem. SUMMARY

[0004] In view of the deficiencies in the prior art, the purpose of the present application is to provide a processing method of an agricultural sprayer with high strength and long service life.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a processing method of an agricultural sprayer, specifically comprising the following steps: S1, preparing raw materials, selecting PE plastic particles or PP plastic particles or PVC plastic particles, and glass fiber material;

[0006] S2, melting and mixing, putting the above-mentioned plastic particles into the feeding hopper of the injection molding machine, and after melting treatment, adding glass fiber, and then fully mixing the molten liquid and glass fiber by the stirrer, and stirring uniformly;

[0007] S3, injection molding, after the upper and lower molds are closed, the mixed molten liquid is introduced into the molding mold, and cooled for 10-15 min;

[0008] S4, demolding and discharging, after cooling, the upper mold of the injection molding mold is opened, and the product is ejected by the ejection mechanism of the injection molding mold;

[0009] S5, cutting, the product obtained in step S4 is transferred to a cutting station, and the outer shell of the sprayer is trimmed by a cutting mold. The trimming area includes the outer wall of the sprayer and the driving installation cavity of the sprayer.

[0010] S6. Strengthening the driving cavity: Several support brackets are provided at a 90-degree angle between the side wall and the bottom of the driving cavity. Each support bracket is evenly arranged along the periphery of the side wall of the cavity. One side of each support bracket abuts against the side wall of the cavity, and the other side of the support bracket abuts against the bottom of the cavity. The support brackets and the driving cavity are fixed by adhesive.

[0011] S7. Casting: An annular casting area is formed between the support bracket and the side wall of the chamber by setting an annular baffle. Casting holes are set on the annular baffle. Molten plastic is evenly sprayed into the casting area through the casting holes until the entire support bracket is covered, and the casting is completed.

[0012] S8. Grinding: After the poured plastic has solidified, remove the annular baffle and grind the pouring area with the product obtained in step S7.

[0013] S9. Air tightness test: After polishing, the product is tested for air tightness using an air tightness testing device to complete the processing.

[0014] The present invention is further configured such that the support bracket is composed of a plurality of support units connected in sequence, each support unit being connected by a flexible fiber rope, each support unit including an "L"-shaped inner skeleton that fits into the joint of the inner wall of the cavity, two extended skeletons that are perpendicularly connected to the transverse and longitudinal portions of the "L"-shaped inner skeleton respectively, and a plurality of arc-shaped unit skeletons that are connected in sequence to the two extended skeletons, each arc-shaped unit skeleton being connected to form an arc-shaped support structure, and the opening direction of the arc-shaped support structure facing the inner skeleton.

[0015] The present invention is further configured such that the connection between the transverse and longitudinal portions of the “L”-shaped inner skeleton forms a first welding point, the connection between the extended skeleton and the inner skeleton forms a second welding point, and the connection between two adjacent arc-shaped unit skeletons forms a third welding point, and the flexible fiber rope connects the first, second and third welding points of two adjacent support units.

[0016] The present invention is further configured such that step S6 includes an adhesive fixing frame for limiting the adhesive position and arranged in a ring at the bottom of the chamber. The adhesive fixing frame includes an adhesive surface that is adhered to the bottom of the chamber and a fixing surface disposed on the surface opposite to the adhesive surface. The fixing surface is provided with a fixing groove for fixing the support unit.

[0017] The present invention is further configured such that an inner flow channel is provided in the fixing groove, the inner flow channel is surrounded by the fixing groove and the bottom of the chamber, and the inner flow channel is configured such that after the support unit is fixed, colloid is introduced into the inner flow channel to form an integral fixation between the support unit and the bottom of the chamber.

[0018] The present invention is further configured such that the spacing between two adjacent support units is between 10mm and 15mm.

[0019] By adopting the above technical solution, the beneficial effects are as follows: 1. Through steps such as preparing raw materials, melting and mixing, injection molding, demolding and blanking, cutting, strengthening the drive cavity, casting, grinding, and airtightness testing, the agricultural sprayer after molding can be strengthened in the upper drive cavity, and its pressure resistance can also be improved. Furthermore, the airtightness test ensures the overall pass rate of the sprayer. In particular, the support bracket forms a strong support between the side wall and bottom of the drive cavity, and the support bracket and the drive cavity are reinforced at the corners. Through the casting process, the support bracket and the inner wall of the drive cavity form an integrated molding effect, thereby improving the overall integrity between the two.

[0020] 2. Further, the support frame is configured as a series of sequentially connected support units. Each support unit is connected by a flexible fiber rope, which can improve the overall integrity between the support units. When the support units are arranged in a ring along the side wall of the chamber, the best fit effect is achieved, and a strong structural support is formed between the side wall and the bottom of the drive chamber, which greatly enhances the strength of the drive chamber structure. Furthermore, each support unit is configured as follows: an "L"-shaped inner skeleton that fits into the joint of the inner wall of the chamber; two extended skeletons that are perpendicularly connected to the horizontal and vertical parts of the "L"-shaped inner skeleton respectively; and several arc-shaped unit skeletons that connect the two extended skeletons in sequence. Each arc-shaped unit skeleton is connected to form an arc-shaped support structure, and the opening direction of the arc-shaped support structure faces the inner skeleton. The "L"-shaped inner skeleton can fit into the drive chamber, and the combination of the extended skeleton and the arc-shaped unit skeletons achieves structural reinforcement of the inner skeleton. After casting, the structural strength of the drive chamber is greatly improved.

[0021] 3. The connection between the horizontal and vertical parts of the "L"-shaped inner frame forms the first welding point, the connection between the extended frame and the inner frame forms the second welding point, and the connection between two adjacent arc-shaped unit frames forms the third welding point. Flexible fiber ropes connect the first, second, and third welding points of two adjacent support units. By adopting the above structural setup, each "L"-shaped inner frame is connected, and the connection distribution of the welding points covers the entire support bracket. This can greatly improve the overall structural strength and also facilitate the regional installation of the support bracket layout.

[0022] 4. In step S6, an adhesive fixing frame is also included to limit the adhesive position and is arranged in a ring at the bottom of the chamber. The adhesive fixing frame includes an adhesive surface that is adhered to the bottom of the chamber and a fixing surface disposed on the opposite surface of the adhesive surface. In order to form a firm bond between the support bracket and the bottom of the chamber, a fixing groove for fixing the support unit is provided on the fixing surface, and an inner flow channel is provided in the fixing groove. The inner flow channel is surrounded by the fixing groove and the bottom of the chamber. The inner flow channel can be configured to allow the input of adhesive after the support unit is fixed, thereby forming an integral fixation between the support unit and the bottom of the chamber. The structural strength is greatly improved and the practicality is strong. Attached Figure Description

Detailed Implementation

[0029] Reference Figures 1 to 5 The following is a further description of an embodiment of the processing method for an agricultural sprayer according to the present invention.

[0030] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0031] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0032] A processing method for an agricultural sprayer specifically includes the following steps: S1, preparing raw materials, selecting PE plastic particles, PP plastic particles, or PVC plastic particles, as well as glass fiber materials;

[0033] S2. Melting and mixing: The above plastic particles are fed into the hopper of the injection molding machine and melted. Then, glass fibers are added, and the melt and glass fibers are thoroughly mixed by an agitator until they are uniform.

[0034] S3. Injection molding: After the upper and lower molds are closed, the mixed molten liquid is poured into the molding die and cooled for 10-15 minutes.

[0035] S4. Demolding and unloading: After cooling, open the upper mold of the injection mold, and the ejection mechanism of the injection mold will eject the product.

[0036] S5. Cutting: Transfer the product obtained in step S4 to the cutting station. Use the cutting mold to trim the rough edges of the sprayer shell. The trimmed areas include the outer wall of the sprayer and the drive mounting cavity 1 of the sprayer.

[0037] S6. Strengthening the driving cavity: Several support brackets 2 are provided at a 90-degree angle between the side wall and the bottom of the driving cavity. Each support bracket 2 is evenly arranged along the periphery of the side wall of the cavity. One side of each support bracket 2 abuts against the side wall of the cavity, and the other side of the support bracket 2 abuts against the bottom of the cavity. The support bracket 2 and the driving cavity are fixed by adhesive.

[0038] S7. Casting: An annular casting area 4 is formed between the support bracket 2 and the side wall of the chamber by setting an annular baffle 3. A casting hole is set on the annular baffle 3. Molten plastic is evenly sprayed into the casting area 4 through the casting hole until the entire support bracket 2 is covered, and the casting is completed.

[0039] S8. Grinding: After the poured plastic has solidified, remove the annular baffle 3 and grind the product obtained in step S7 on the pouring area 4.

[0040] S9. Air tightness test: After polishing, the product is tested for air tightness using an air tightness testing device to complete the processing.

[0041] This invention, through steps such as raw material preparation, melt mixing, injection molding, demolding and blanking, material cutting, drive cavity reinforcement, casting, grinding, and airtightness testing, ensures that the molded agricultural sprayer has reinforcement in the upper drive cavity, improving its pressure resistance. Furthermore, the airtightness test guarantees the overall pass rate of the sprayer. Specifically, the support bracket 2 provides strong support between the side walls and bottom of the drive cavity, reinforcing the corners of the drive cavity. The casting process integrates the support bracket 2 with the inner wall of the drive cavity, enhancing their overall integrity.

[0042] Furthermore, the support bracket 2 is composed of several sequentially connected support units 20. Each support unit 20 is connected by a flexible fiber rope 21. Each support unit 20 includes an "L"-shaped inner skeleton 201 that fits into the joint of the inner wall of the cavity, two extended skeletons 202 that are perpendicularly connected to the transverse and longitudinal portions of the "L"-shaped inner skeleton 201 respectively, and several arc-shaped unit skeletons 203 that are sequentially connected to the two extended skeletons 202. Each arc-shaped unit skeleton 203 is connected to form an arc-shaped support structure 204, and the opening direction of the arc-shaped support structure 204 faces the inner skeleton 201. Further configuring the support bracket 2 as a group of several sequentially connected support units 20, with each support unit 20 connected by a flexible fiber rope 21, can improve the overall integrity between each support unit 20. When the support units 20 are arranged in a ring along the side wall of the cavity, a The optimal fit creates strong structural support between the sidewalls and bottom of the drive chamber, greatly enhancing the structural strength of the drive chamber. Each support unit 20 includes an "L"-shaped inner skeleton 201 that fits into the joints of the inner wall of the chamber, two extended skeletons 202 that are perpendicularly connected to the transverse and longitudinal portions of the "L"-shaped inner skeleton 201, and several arc-shaped unit skeletons 203 that connect the two extended skeletons 202 in sequence. Each arc-shaped unit skeleton 203 is connected to form an arc-shaped support structure 204, with the opening of the arc-shaped support structure 204 facing the inner skeleton 201. The "L"-shaped inner skeleton 201 fits into the drive chamber, and the combination of the extended skeletons 202 and the arc-shaped unit skeletons 203 strengthens the structure of the inner skeleton 201. After casting, the structural strength of the drive chamber is greatly improved.

[0043] Furthermore, the connection between the transverse and longitudinal portions of the "L"-shaped inner skeleton 201 forms a first welding point 205, the connection between the extended skeleton 202 and the inner skeleton 201 forms a second welding point 206, and the connection between two adjacent arc-shaped unit skeletons 203 forms a third welding point 207. The flexible fiber rope 21 connects the first, second, and third welding points of two adjacent support units 20. By adopting the above structural arrangement, each "L"-shaped inner skeleton 201 is connected, and the connection distribution of the welding points covers the entire support bracket 2, which greatly improves the overall structural strength and facilitates the regional installation of the support bracket 2.

[0044] Further, step S6 also includes an adhesive fixing frame 5 arranged in a ring at the bottom of the chamber to limit the adhesive position. The adhesive fixing frame 5 includes an adhesive surface 50 that is adhered to the bottom of the chamber and a fixing surface 51 disposed on the opposite surface of the adhesive surface 50. The fixing surface 51 is provided with a fixing groove 52 for fixing the support unit 20. The fixing groove 52 is provided with an inner flow channel 520. The inner flow channel 520 is surrounded by the fixing groove 52 and the bottom of the chamber. The inner flow channel 520 is configured to form an integral fixation between the support unit 20 and the bottom of the chamber by introducing adhesive into the inner flow channel 520 after the support unit 20 is fixed. In step S6, an adhesive fixing frame 520 arranged in a ring to limit the adhesive position is also included. The adhesive mounting bracket 5 is located at the bottom of the chamber. The adhesive mounting bracket 5 includes an adhesive surface 50 that is adhered to the bottom of the chamber and a fixing surface 51 located on the opposite surface of the adhesive surface 50. In order to form a strong bond between the support bracket 2 and the bottom of the chamber, a fixing groove 52 for fixing the support unit 20 is provided on the fixing surface 51, and an inner flow channel 520 is provided in the fixing groove 52. The inner flow channel 520 is surrounded by the fixing groove 52 and the bottom of the chamber. The inner flow channel 520 can be configured to allow the input of colloid after the support unit 20 is fixed, thereby forming an integral fixation between the support unit 20 and the bottom of the chamber. The structural strength is greatly improved and the practicality is strong.

[0045] In this embodiment of the invention, the main structure of the "L"-shaped inner skeleton 201 is as follows: several fixed distribution frames 61 are prepared, and several mounting holes 610 are provided on each fixed distribution frame 61. Each plastic rod 62 is passed through each mounting hole 610, and the opposite ends of each plastic rod 62 are welded together to form an "L"-shaped structure. The cross-sectional structure of the fixed distribution frame 61 can be rectangular, circular, or elliptical. With the above-mentioned inner skeleton 201 structure, after casting, the coating will form an adhesion layer on the periphery of each plastic rod 62 and then spread to the area between each support unit 20, thereby forming a very strong bonding strength between the inner skeleton 201 and the coating, which greatly improves the strengthening effect on the drive chamber.

[0046] Furthermore, the spacing between two adjacent support units 20 is between 10mm and 15mm. In this embodiment of the invention, the spacing between support units 20 can be adjusted according to the size of the drive chamber. Controlling the spacing between support units 20 to 10-15mm is to ensure higher structural strength between the support units 20 after casting. When the spacing between two adjacent support units 20 is less than 10mm, the support units 20 are too closely arranged, which not only affects the uniform distribution of the adhesive during casting, but also directly affects the overall structural strength. When the spacing between support units 20 is greater than 15mm, firstly, the coverage area of ​​the support units 20 cannot be effectively guaranteed, and secondly, the support units 20 will not have effective adhesion points for the adhesive due to the excessive spacing, thus affecting the strength of the adhesive and directly affecting the service life. Therefore, controlling the spacing between support units 20 to 10-15mm can effectively ensure the uniformity of the adhesive application and improve the structural strength, greatly enhancing practicality.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included within the protection scope of the present invention.
