Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery buckets, in particular to an agricultural machinery bucket which is convenient for loading and unloading materials. Background Art

[0002] Agricultural machinery refers to various machines used in the production process of crop planting and animal husbandry, as well as in the primary processing and treatment of agricultural and livestock products; and micro-tillage machines are one of the agricultural machinery. Micro-tillage machines are powered by small diesel engines or gasoline engines, and have the characteristics of light weight, small size, and simple structure. Micro-tillage machines are widely used in dry land, paddy fields, orchards, etc. in plains, mountainous areas, and hills. Equipped with corresponding machinery, they can be used for pumping, power generation, spraying, and spraying. They can also be towed by trailers for short-distance transportation. Micro-tillage machines can be used freely in the fields, which is convenient for users to use and store, eliminating the trouble that large agricultural machinery cannot enter mountain fields.

[0003] At present, in order to facilitate the transportation of materials used in agricultural work, such as bricks, sand, fertilizers, and farm tools, through the traction head of a micro-tillage machine, a bucket component is usually installed at the traction end of the traction head of a micro-tillage machine, and the materials are transported in the field through the hook component. The existing agricultural machinery bucket is generally a single storage box. Although it can transport materials, it is unable to unload materials according to different materials during transportation. For example, when transporting fertilizers or sand through the bucket component, subsequent unloading cannot be carried out and only stacking unloading can be carried out, so that manual auxiliary operations are required later, which affects work efficiency. Summary of the invention

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0044] Embodiment 1:

[0045] See attached Figure 1-9 , an agricultural machinery bucket for facilitating material loading and unloading, comprising a bucket mechanism mounted on a traction end of an agricultural machinery traction head 1;

[0046] The bucket hanging mechanism includes a storage hopper 3, one side of the storage hopper 3 is set to be open, and the open part of the storage hopper 3 is rotatably connected to a baffle 32 through a rotating shaft 31;

[0047] By detachably installing the storage hopper 3 on the traction end of the agricultural machine traction head 1, it is convenient to use the agricultural machine traction head 1 to transport materials required for crops, such as bricks, sand, fertilizers, and agricultural tools;

[0048] The top of the storage hopper 3 is fixedly connected with two push handles 6, the bottom of the storage hopper 3 is fixedly connected with a connecting beam 7, and auxiliary rollers 8 are installed on both sides of the bottom of the connecting beam 7;

[0049] Through the setting of the connecting crossbeam 7, two auxiliary rollers 8 are installed at the bottom of the storage hopper 3, so that the storage hopper 3 can follow the agricultural machine traction head 1 to walk, and improve the orderliness of its boring transportation. It should be noted here that the number of connecting crossbeams 7 can be set to two, and the number of auxiliary rollers 8 is four, which is used to further improve the stability of the storage hopper 3 when it is used alone;

[0050] One side of the storage hopper 3 is detachably connected to the traction end block 2 of the agricultural machine traction head 1 through a disassembly component 4;

[0051] The storage hopper 3 is detachably connected to the traction end block 2 of the agricultural machinery traction head 1 through the disassembly and assembly parts 4, thereby facilitating the installation of the storage hopper 3 and using it in a linked manner. At the same time, it is also convenient to disassemble the storage hopper 3 to form a separate use of the bucket, thereby further improving the use effect of the agricultural machinery bucket.

[0052] See attached Figures 3 to 5 , the rotating shaft 31 is fixed to the top of the baffle 32, and both ends of the rotating shaft 31 are rotatably connected to the inner top of the storage hopper 3;

[0053] The top of the baffle 32 is rotatably connected to the top of the storage hopper 3 by a rotating shaft 31, so that when the baffle 32 is turned over, the material inside the storage hopper 3 is intermittently discharged from the bottom, forming an orderly unloading operation;

[0054] A receiving hopper 33 is fixedly connected to one side of the bottom of the storage hopper 3, and a material guide frame 34 is fixedly connected to the bottom of the receiving hopper 33;

[0055] The receiving hopper 33 is provided to receive the material discharged from the end of the docking hopper 33 and evenly guide the material through the guide frame 34 to form a quantitative unloading operation;

[0056] The storage hopper 3 is provided with two control components 5 for controlling the baffle 32;

[0057] By setting the control component 5, it is convenient for the staff to control the flipping of the baffle 32 by hand, thereby forming a control of the discharge amount, thereby improving the diversity of its material loading and unloading.

[0058] See attached Figure 3 and Figure 6 The control assembly 5 includes a movable frame 51 slidably connected to the outer wall of the storage hopper 3 and an adjusting member 54 for transversely adjusting the movable frame 51. One end of the movable frame 51 is fixedly connected to a movable rod 52. The outer surface of the movable rod 52 is penetrated with a sleeve 53 for limiting the baffle 32.

[0059] The setting of the sleeve 53 is used to limit the flipping angle of the baffle 32, so as to form the uniformity of the subsequent sand laying. The sleeve 53 is inserted into the outer surface of the sleeve 53, so that the sleeve 53 can be moved sideways, so that the sleeve 53 completely loses the lock on the baffle 32, thereby facilitating the dumping unloading work, and having the function of multiple unloading methods.

[0060] See attached Figure 6 The adjusting member 54 includes a movable frame 541 fixed on the outer wall of the storage hopper 3, and a moving block 542 is slidably connected to the movable frame 541 in a transverse sliding manner. The moving block 542 is fixedly connected to the moving frame 51 through a connecting rope 543;

[0061] By controlling the lateral movement of the moving block 542, the connecting rope 543 can be used to drive the moving frame 51 to adjust left and right. By adjusting the moving frame 51 left and right, the movable rod 52 and the sleeve 53 can be driven to adjust left and right, and then the position of the baffle 32 can be controlled, so as to meet the expansion of the baffle 32 at different angles, thereby forming a gap-type unloading operation, which is suitable for laying sand in the field and improves the uniformity of unloading.

[0062] The top of the movable frame 541 is provided with a strip-shaped slide groove 544, and the inner wall of the strip-shaped slide groove 544 is provided with a group of bayonet holes. The top of the moving block 542 is slidably connected with a control rod 545 in a longitudinal sliding manner, and the control rod 545 extends to the top of the movable frame 541 through the strip-shaped slide groove 544;

[0063] The setting of the control rod 545 facilitates the staff to control the moving block 542. The opening of the strip slide groove 544 facilitates the lateral movement of the control rod 545. The setting of the bayonet facilitates the locking of the control rod 545 after the lateral movement, thereby ensuring the stability of the moving block 542 after lateral adjustment, thereby satisfying the control of different inclinations of the baffle 32.

[0064] See attached Figure 7 The disassembly and assembly part 4 is fixed to a U-shaped frame 41 on one side of the storage hopper 3, two groups of clamping holes 42 are opened inside the U-shaped frame 41, and one end of the traction end block 2 extends to the inside of the U-shaped frame 41, an auxiliary hole is opened at one end of the traction end block 2, and a magnetic latch 43 is inserted between the auxiliary control and the inside of one pair of clamping holes 42;

[0065] By setting the magnetic latch 43, which is inserted into the overlapping clamping hole 42 and the auxiliary hole, the storage hopper 3 can be detachably connected to the traction end block 2 of the agricultural machine traction head 1, so that the storage hopper 3 can be driven to move by the walking movement of the agricultural machine traction head 1 to form a material conveying operation;

[0066] The two sets of latch holes 42 are provided to improve the stability of the magnetic latch 43 after installation, and the magnetic latch 43 is made of magnetic material that can be adsorbed on the metal U-shaped frame 41, so as to further improve the stability after installation and prevent the problem of self-detachment.

[0067] There are several clamping holes 42 in each group, so as to facilitate the installation of the traction end block 2 at different heights on the storage hopper 3, so as to meet the requirement that the storage hopper 3 moves in an inclined or horizontal state, which not only improves the stability of material transportation, but also reduces the problem of material shaking out through the transportation of the storage hopper 3 in an inclined state.

[0068] Embodiment 2: Based on embodiment 1, the difference is that;

[0069] See attached Figure 8 and Fig. 9 , the rotating shaft 31 is fixed to the bottom of the baffle 32, and both ends of the rotating shaft 31 are rotatably connected to the inner bottom of the storage hopper 3;

[0070] The bottom of the baffle 32 is rotatably connected to the inner bottom of the storage hopper 3 by a rotating shaft 31, so that the baffle 32 can be tilted and unfolded from top to bottom, thereby facilitating the loading and unloading of large materials such as agricultural tools and crops, improving the convenience of operation, and further improving the use range of the agricultural machinery bucket;

[0071] One side of the storage hopper 3 is rotatably connected to two limit blocks 35 for limiting the baffle 32;

[0072] By turning over the limiting block 35 , the baffle 32 can be limited, thereby ensuring the stability of the baffle 32 .

[0073] Embodiment 3: Based on embodiment 1, the difference is that;

[0074] See attached Figure 3 , Figure 4 and Figure 7 A discharge port is provided at the bottom of the storage hopper 3, and a material discharge assembly for controlling the discharge port is provided at the bottom of the storage hopper 3;

[0075] The opening of the discharge port facilitates the discharge of the fertilizer stored in the storage hopper 3, thereby forming a fertilization operation of the agricultural machinery. The setting of the discharge assembly is used to control the discharge port, thereby forming a quantitative intermittent fertilization operation, thereby improving the diversity of its material discharge;

[0076] The unloading assembly includes a flip block 9 rotatably connected to the bottom of the storage hopper 3 through a rotating shaft and a flip member for flipping the flip block 9. A blocking plate 10 for blocking the discharge port is fixedly connected to one side of the flip block 9.

[0077] By setting the flipping piece, the flipping block 9 can be moved in a fan-shaped manner at the position of the rotating shaft, and then the blocking plate 10 can be driven to move in a fan-shaped manner. The fan-shaped movement of the blocking plate 10 can block the discharge port, or lose the blockage of the discharge port, thereby facilitating the selective discharge of the fertilizer stored in the storage hopper 3. It has a good agricultural machinery fertilization function, and further improves the functionality and practicality of the agricultural machinery. It should be noted here that the flipping piece includes but is not limited to a motor or an electric telescopic rod for flipping the flipping block 9.

[0078] The flip member includes a connecting frame 11 hinged to the other side of the flip block 9 and a U-shaped block 12 fixed to the bottom of the traction end block 2, a T-shaped plug 13 is inserted into the U-shaped block 12, and a through hole for inserting the T-shaped plug 13 is opened at one end of the connecting frame 11;

[0079] One end of the connecting frame 11 is rotatably connected to the traction end block 2 through a T-shaped latch 13, so that when the worker lifts the control handle on the agricultural machine traction head 1 upward, the connecting frame 11 can move upward synchronously, thereby driving the flip block 9 to move in a fan-shaped manner at the position of the rotating shaft, thereby making it possible for the blocking plate 10 to lose the blocking of the discharge port, thereby facilitating the discharge of fertilizers in the storage hopper 3, thereby forming a fertilization operation;

[0080] On the contrary, by pressing the control handle on the agricultural machinery traction head 1 downward, the blocking plate 10 can block the discharge port, thereby stopping the fertilization work. It has good fertilization and material discharge work, and there is no need to set up a separate electric drive source for control, which improves the convenience of fertilization.

[0081] It should be noted that the term "comprises" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article, or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article, or device that includes the element.

[0082] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
