Abstract
Description
Technical Field
[0001] This invention relates to the field of material transport equipment, specifically a hand-held spill-proof material bucket and its usage method. Background Technology
[0002] During the decoration and painting process, the paints, coatings, and small granular materials used are easily spilled during disassembly, relocation, and mixing because the oil is mostly transported manually during the operation. This can cause pollution to other parts of the work area, and manual cleaning and collection are quite complicated. Summary of the Invention
[0003] In order to overcome the shortcomings of the prior art and provide a transportation tool that is easy to load, avoids spillage, and is highly adaptable, this invention discloses a hand-held spill-proof material bucket and its usage method.
[0004] The present invention achieves its objective through the following technical solution:
[0005] A portable spill-proof hopper includes an outer hopper, which is a cylindrical shell. It is characterized by further including an inner hopper, a steering ring, and a control device.
[0006] The top of the inner wall of the outer barrel is provided with two external shaft holes, which are located at both ends of a diameter at the opening of the inner cavity of the outer barrel. The bottom of the outer barrel is provided with a discharge hole, and a plug is provided in the discharge hole. A sealing ring is embedded between the plug and the discharge hole.
[0007] The inner tub is a hemispherical shell with two inner shaft holes on the bottom surface, located at both ends of a diameter on the bottom surface of the inner tub.
[0008] The outer diameter of the steering ring and the inner diameter of the outer barrel form a clearance fit, and the inner diameter of the steering ring and the outer diameter of the bottom surface of the inner barrel form a clearance fit. Two external convex shafts and two internal convex shafts are respectively provided on the outer and inner sides of the steering ring. The outer diameter of the external convex shaft and the diameter of the outer shaft hole form a clearance fit, and the outer diameter of the internal convex shaft and the diameter of the inner shaft hole form a clearance fit. The two external convex shafts and the two internal convex shafts are respectively located at both ends of a diameter of the steering ring, and the line connecting the two external convex shafts and the line connecting the two internal convex shafts are perpendicular to each other. The two external convex shafts of the steering ring are respectively fitted into an outer shaft hole so that the steering ring is rotatably set at the opening of the outer barrel, and the two internal convex shafts of the steering ring are respectively fitted into an inner shaft hole so that the inner barrel is rotatably set inside the steering ring with the bottom surface open upward.
[0009] The control device includes a spring, a top block, a wrench, and a corrugated sleeve.
[0010] The top of the spring abuts against the apex of the inner barrel's hemisphere, and the bottom of the spring abuts against the top of the top block. The bottom of the top block is a bevel or a convex arc surface. The wrench includes an outer handle and an inner rod. The inner end of the outer handle is connected to the outer end of the inner rod via a connecting rod. The outer handle and the inner rod are perpendicular to the connecting rod of the wrench, and the outer handle and the inner rod form an acute angle. The inner rod passes into the outer barrel and is located directly below the top block. The outer handle is located outside the outer barrel. The connecting rod of the wrench is rotatably inserted into the barrel wall of the outer barrel. A corrugated sheath is fitted over the spring and the top block.
[0011] When the outer end of the outer handle is pulled upward to the vertical position, the inner end of the inner rod faces diagonally downward, the inner rod and the top block disengage, and the spring is relaxed. When the outer end of the outer handle is pulled to the horizontal position, the inner end of the inner rod faces diagonally upward, the inner rod and the top block disengage, and the spring is relaxed. When the outer end of the outer handle is pulled downward to the vertical position, the inner end of the inner rod abuts against the bottom end of the top block and pushes the top block upward through the inclined surface of the bottom end of the top block. The top block compresses the spring, and the spring force fixes the inner barrel.
[0012] The hand-held spill-proof bucket is characterized in that it also includes a handle, with both ends of the handle located on the upper part of the outer side wall of the bucket.
[0013] The hand-held spill-proof bucket is characterized in that: the inner bottom surface of the outer bucket is a frustum, and the frustum slopes down from the outer edge of the inner bottom surface of the outer bucket toward the discharge hole.
[0014] The aforementioned hand-held spill-proof hopper is characterized by:
[0015] The angle formed by the outer handlebar and the inner bar is between 30° and 45°;
[0016] The slope of the inner bottom surface of the outer barrel is between 0.05 and 0.2.
[0017] The method of using the aforementioned hand-held spill-proof material bucket is characterized by the following steps:
[0018] S1. Discharge: Pour liquid materials such as oil and dye into the inner drum;
[0019] S2. Handling: When handling liquid materials, move the outer end of the outer handle upward to the vertical position or move the outer end of the outer handle to the horizontal position. At this time, the inner end of the inner rod faces diagonally downward or diagonally upward. The inner rod and the top block are disengaged, the spring is in a relaxed state, and the inner barrel is not affected by the elastic force of the spring. Under its own weight, it always maintains a vertical state to prevent liquid materials from spilling.
[0020] S2. Pouring: When pouring liquid material, pull the outer end of the outer handle downward to the vertical position. At this time, the inner end of the inner rod abuts against the bottom end of the top block and pushes the top block upward through the inclined surface of the bottom end of the top block. The top block compresses the spring, and the inner barrel is fixed by the elastic force of the spring. Then pour the liquid material in the inner barrel.
[0021] S3. Collection: If liquid material flows in from the gap between the outer and inner drums, the liquid material will collect at the bottom of the outer drum. Open the plug and the liquid material will flow out from the discharge hole.
[0022] S4. Cleaning: Move the outer end of the outer handle upward to the vertical position or move the outer end of the outer handle to the horizontal position to relax the spring. Then tilt the outer tub to the horizontal position, and the inner tub will remain vertical under its own weight. Clean by the gap between the opening of the inner tub and the inner wall of the outer tub.
[0023] This invention solves the problem of waste and pollution caused by spillage of liquid materials during movement and handling, and realizes the recycling and reuse of spilled materials.
[0024] The present invention has the following beneficial effects:
[0025] 1. Operability: The material barrel is easy to load, transport and clean. It can load and unload various oils and granular materials. Internal spills and cleaning are done by using the external wrench. It is small in size, flexible to lift and handle, simple to learn and highly operable.
[0026] 2. Applicability: This container is suitable for transporting and mixing oils up to 6.4L in volume. It is not easy to spill outside the container during the process. It weighs about 2.5Kg and has a wide range of applications.
[0027] 3. Economic efficiency: It avoids spillage during transportation, reduces secondary pollution and the need for secondary cleanup, and indirectly reduces the manpower required for secondary pollution cleanup. Attached Figure Description
