[0039] In the description of the utility model, the terms "first", "second" are only used for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more features. In the description of the utility model, the meaning of "multiple" is two or more than two, unless otherwise specifically limited.

[0040] Referring to Figures 1-6 As shown in FIG. 1, a shoulder and back sling type waist type material applying bucket, comprising:

[0041] The bottom sheet 1 is provided with an arc-shaped groove 11 in the middle of one side of the bottom sheet 1, and the arc-shaped groove 11 matches the side waist part;

[0042] The baffle 2 is outwardly inclined and arranged on the outer edge of the bottom sheet 1, the baffle 2 is provided with a group of mounting holes 3 on the side facing the arc-shaped groove 11, and a shoulder strap 4 connects the two mounting holes 3;

[0043] The bottom sheet 1 and the baffle 2 cooperate to form a containing part 5, and the containing part 5 is used for containing materials;

[0044] The arc-shaped groove 11 divides the containing part 5 into a first containing area 51 and a second containing area 52 in the middle;

[0045] The bottom sheet 1 is provided with a guide groove 53 on the side facing the baffle 2, the depth of the guide groove 53 gradually increases from the first containing area 51 to the second containing area 52, and a convergence area 54 is formed in the middle of the second containing area 52;

[0046] The material in the first containing area 51 enters the convergence area 54 in the second containing area 52 through the guide groove 53.

[0047] In use, first, the user fixes the material applying bucket on the body by the shoulder strap 4. Through the arc-shaped groove 11 adopted by the barrel body, the side waist part can be better fitted, and stability and comfort can be ensured. When loading materials, the materials are divided into the containing part 5 in the barrel through the top. During the material applying process, the materials flow to the convergence area 54 in the barrel through the guide groove 53. Finally, the user applies the materials through the set outlet.

[0048] Through the setting of the guide groove 53, the materials can flow naturally along the groove to the convergence area 54, so that the materials can be concentrated, and the application is more uniform. When the material in the material applying barrel is more, due to the height difference of the material stacking, it will actively move towards the output end. When the material is less, the height area of the material stacking is consistent, through the guide groove 53, the material at the storage end can be more stably moved towards the output end, and the remaining material can be accurately flowed to the convergence area 54, so that the user can take and apply conveniently.

[0049] By the outwardly inclined stopper 2, not only can the longitudinal shape curve of the side waist and the crotch be fully met, but also the shoulder strap 4 can be cooperated with the fixed end arranged near one side of the arc-shaped groove 11, so that the arc-shaped groove 11 is fitted to the side waist curve, and the material in the material applying barrel and the shoulder strap 4 form a triangular force, so that the arc-shaped groove 11 is further fitted to the side waist curve. Through the double action, the material applying barrel can be more stably hung on the side waist of the user, the shaking is reduced, and the stability is improved.

[0050] Unlike the traditional material applying barrel, the material applying barrel of the present scheme can reasonably distribute the weight of the material, reduce shaking, improve stability, and thus reduce the pressure on the shoulder and the side waist, so that it is more comfortable to carry for a long time. The traditional material applying barrel structure is relatively simple, often without effective material guiding, and uneven loading of the material is prone to occur. Through the design of the guide groove 53, the material can smoothly flow to the convergence area 54, so that more uniform application is realized.

[0051] In terms of ergonomics, the traditional material applying barrel often causes the pressure to concentrate on the shoulder or the side waist, and long-term use will feel uncomfortable. Through the design of the arc-shaped groove 11 and the outwardly inclined stopper 2, the present scheme can better fit the human body curve, evenly distribute the weight, and greatly improve the comfort of use.

[0052] In addition, the traditional material applying barrel often needs manual adjustment or intervention, and the operation is not convenient enough. Through the optimized structure design, the user can easily control the application speed and amount during the material application process, reducing manual intervention, and the operation is more simple and efficient.

[0053] Summary

[0054] The present scheme improves the traditional material applying barrel in many aspects, solves the problems of uneven material application and uncomfortable use, etc. Compared with the prior art, the present scheme has obvious advantages in comfort, material application uniformity and flowability, and is particularly suitable for work scenes that need to be used for a long time, such as agriculture, gardening and material spreading, etc.

[0055] In order to make the material flow more smoothly, the guide groove 53 is arc-shaped from the first containing area 51 to the second containing area 52, and the width of the guide groove 53 gradually decreases along the arc-shaped direction, and the end thereof is connected with the convergence area 54.

[0056] The arc-shaped guide groove 53 can effectively avoid sudden obstacles during the flow of the material. The material flows along the curved trajectory, which can more naturally follow the guidance of the groove, reducing the flow or jamming caused by straight lines or excessively steep angles. The smooth transition of the arc-shaped design makes it easier for the material to move smoothly to the next part, ensuring a more stable application process.

[0057] The gradually narrowing width of the guide groove 53 can control the flow of the material. As the material flows along the arc-shaped groove, the gradually narrowing width of the groove can precisely limit and guide the flow rate of the material, effectively controlling the movement speed of the material and making the material distribution more uniform.

[0058] The gradually narrowing structure of the guide groove 53 helps to precisely control the convergence and distribution of the material at the end. Before entering the convergence area 54, the material will be concentrated due to the narrowing of the groove, which makes the material more accurately gather in the convergence area 54, avoiding uneven distribution or scattering during the application process, thereby improving the accuracy and efficiency of the application.

[0059] The gradually narrowing design of the groove can reduce the risk of clogging and jamming. If the guide groove 53 is too wide or not properly designed to control the flow of the material, the material is prone to clogging due to excessive accumulation or irregular shape of the material. The gradually narrowing groove design can reduce the risk of clogging to some extent, as it allows the material to gradually enter smaller spaces, slowing down the flow and preventing large blocks of material from blocking.

[0060] To improve the efficiency of material sliding, the thickness of the bottom sheet 1 gradually decreases from the first holding area 51 to the second holding area 52, forming a first inclined surface 12 in the holding part 5. The inclination of the first inclined surface 12 is 5-10°.

[0061] By setting the inclined surface, the material in the holding part 5 can naturally slide downward by gravity. Due to the inclination formed by the gradually decreasing thickness, the material is more easily guided in the target direction without the need for additional pushing force, thereby improving the overall flow efficiency.

[0062] Not only avoids material retention, but also reduces waste. The flat bottom structure is prone to accumulation of small or sticky materials, which is not easy to discharge, while the first inclined surface 12 can reduce the retention of materials at the bottom of the holding part 5, helping them smoothly enter the next process or groove, reducing material residue, avoiding waste, and improving utilization.

[0063] By gradually reducing the thickness to form an inclined surface, a small part of the material that escapes outside the guide groove 53 can be re-collected into the convergence area 54 through the diversion of the inclined surface.

[0064] And this inclined surface structure is also conducive to the manufacturing process, especially in injection or compression molding, the angle of inclination can be as a draft angle, facilitate the product from the mold smoothly out, improve production efficiency and yield.

[0065] In order to facilitate the nested stack, save storage and transportation space, the width of the open area above the baffle 2 is greater than the width of the lower closed area;

[0066] Among them, the baffle 2 is inclined to the placement surface by 75-80°.

[0067] Through the structure of wide at the top and narrow at the bottom, the barrels can be smoothly inserted and nested, and will not be stuck; multiple barrels can be tightly stacked, greatly compressing the volume, effectively saving storage and logistics space, and reducing transportation costs.

[0068] And the baffle 2 is inclined by 75-80°, which prevents sticking and is stable. The inclined angle allows the baffle 2 to play a certain guiding and limiting role, and will not hinder the insertion of the barrel body due to the too large vertical angle. 75-80° is an optimized angle that takes into account the stability of the structure and the smoothness of the nesting, which is not easy to deform and allows the barrels to be stacked smoothly.

[0069] In order to avoid over-tightening or difficulty in separating, if the upper and lower area widths are consistent or the baffle 2 is too straight, the barrels are prone to "suction" or sticking, making it difficult to separate manually. Through shape and angle guidance, a reasonable separation gap is formed, making it easy to insert and remove, and improving the convenience of use.

[0070] In order to separate the barrels that are nested together, the baffle 2 is provided with an extension 24 extending outward above the first and second holding areas 51 and 52, and anti-slip patterns can also be provided on the surface of the extension 24.

[0071] The extension 24 of the baffle 2 is located above the first and second holding areas 51 and 52 and extends outward, which can effectively increase the coverage area of the baffle 2 and provide stronger support and stability. It can prevent the items or objects in the holding area from tilting or shifting due to external impact or imbalance during use, improving the safety of the overall structure.

[0072] The extension 24 forms a handle, and the user can separate two material application barrels by holding two adjacent handles.

[0073] And the anti-slip patterns are provided on the upper and lower surfaces of the extension 24, which can significantly improve the friction with the contacted objects. This makes the objects less likely to slide when placed, even if the objects are heavy or have a certain sliding property, they can remain stable and prevent the objects from sliding or falling due to insufficient friction.

[0074] In order to improve the strength and stability of the blocking piece 2, the bottom sheet 1 comprises a first sub-piece 15 located in the first containing area 51, the first sub-piece 15 is provided with a first corner 151, a second corner 152 and a third corner 153, the first corner 151, the second corner 152 and the third corner 153 are all 90°, and the blocking piece 2 forms a first material blocking part 21 around the first corner 151, the second corner 152 and the third corner 153.

[0075] Through the cooperation of the first sub-piece 15 and the blocking piece 2, a square containing area can be formed around it, which can contain more materials.

[0076] In order to make the internal corners of the material applying barrel not easy to store materials, and to make it more convenient when stacking multiple material applying barrels, the corners of the first sub-piece 15 are chamfered, specifically, the outer side of the first corner 151 and the second corner 152 is provided with a chamfer of 10-30°.

[0077] Through the cooperation of the chamfered design and the blocking piece 2, a smooth curved surface can be formed on the outside, removing the sharp edges, avoiding scratches or other accidental injuries during operation.

[0078] At the same time, the chamfering of the edge can effectively disperse the external pressure, avoid stress concentration, reduce material fatigue damage, and improve the durability and long-term stability of the product.

[0079] The internal edge of the first containing area 51 formed by the blocking piece 2 and the first sub-piece 15 is an arc structure, which makes the internal corners of the material applying barrel not easy to store materials, and also makes it more convenient when stacking multiple material applying barrels.

[0080] The second containing area 52, which is used by the user to take materials, needs to be kept relatively close to the user's abdomen side, so it needs to pay attention to comfort, the bottom sheet 1 comprises a second sub-piece 16 located in the second containing area 52, the second sub-piece 16 is an arc-shaped structure, the maximum width of the first sub-piece 15 and the second sub-piece 16 is consistent, the blocking piece 2 forms a second material blocking part 22 around the second sub-piece 16, the arc-shaped groove 11 is located at the junction of the first sub-piece 15 and the second sub-piece 16, and the junction of the first material blocking part 21 and the second material blocking part 22 is a third material blocking part 23 corresponding to the arc-shaped groove 11.

[0081] Through the arc edge of the second sub-piece 16, compared with sharp corners or right angles, it can more evenly distribute stress, avoid stress concentration, and maintain the comfort of the user's abdomen.

[0082] In addition, the second containing area 52 formed by the arc-shaped structure of the second segment 16 and the baffle 2 can also facilitate the nesting or sliding of the multiple material buckets when stacked, especially in structures that require sliding, insertion or positioning, thereby avoiding jamming or alignment difficulties and improving assembly efficiency and accuracy.

[0083] Since the material bucket needs to contain materials, the carrying capacity needs to be designed, so the bottom piece 1 is fixedly installed with reinforcing ribs 13, and the density of the reinforcing ribs 13 under the first segment 15 is greater than that of the reinforcing ribs 13 under the second segment.

[0084] As a further improvement, the width of the two reinforcing ribs 13 adjacent to the first segment 15 is 1-2 cm, and the width of the two reinforcing ribs 13 adjacent to the second segment is 2-3 cm.

[0085] In the connection area of the first segment 15 and the second segment 16, the reinforcing ribs 13 form a triangular structure area 131.

[0086] Since the reinforcing ribs 13 are usually used to distribute loads and enhance the carrying capacity of the structure, especially in areas with greater stress. By increasing the reinforcing ribs 13 at the bottom of the bottom piece 1, the overall strength and rigidity of the bottom piece 1 can be significantly improved, preventing deformation or damage during work.

[0087] The reinforcing ribs 13 can improve the stability of the bottom piece 1 by dispersing external pressure. In particular, in thinner or larger structures, the reinforcing ribs 13 can effectively reduce warping, bending and other problems caused by external forces, thereby enhancing the overall anti-deformation ability.

[0088] Among them, about setting different density reinforcing ribs 13:

[0089] The density of the reinforcing ribs 13 under the first segment 15 and the second segment 16 is different. Since the first segment 15 corresponding to the first containing area 51 has more space and carries more materials, the density of the reinforcing ribs 13 under the first segment 15 is greater. By increasing the density, the larger load can be effectively dispersed and conducted, avoiding local stress from being too large to cause structural damage.

[0090] The density of the reinforcing ribs 13 under the second segment 16 is smaller, which means that the force on this area is smaller or more evenly distributed. Designing reinforcing ribs 13 with smaller density can not only save materials, but also will not affect the strength and stability of the structure.

[0091] By reasonably setting the density of the reinforcing ribs 13 according to the stress situation of different areas, the overall strength can be guaranteed while avoiding overdesign, reducing material waste and improving the overall cost performance.

[0092] Because of the existence of relatively concentrated local stress in the first segment 15 area, the relatively narrow reinforcing rib 13 can finely distribute the mechanical load while maintaining the strength, thereby improving the stress uniformity of the structure.

[0093] The required reinforcing rib 13 width under the second segment 16 is relatively large because the force borne by this area is relatively small, and therefore, the use of a relatively wide reinforcing rib 13 can reduce the amount of material used and lower the cost.

[0094] In addition, a triangular structure area is formed at the connecting area of the first segment 15 and the second segment 16, which can effectively increase the strength and stability of the connecting part. As the most stable geometric shape, the triangle can better disperse the force and improve the tensile and shear performance of the connecting part, thereby avoiding damage or deformation of the connecting part due to uneven force.

[0095] In the embodiment, the application barrel is made of plastic material.

[0096] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
