Description

Technical Field

[0001] The present invention relates to the field of skid steer loader unloading, in particular to an automatic and efficient unloading device for a skid steer loader. Background Art

[0002] A skid steer loader, also known as a skid loader, multi-purpose engineering vehicle, or multi-purpose engineering machine, is a wheeled, special-purpose chassis equipment that uses the linear speed difference of the wheels on both sides to achieve vehicle steering. It is mainly used in situations where the work site is small, the ground is uneven, and the work content changes frequently. It is suitable for infrastructure construction, industrial applications, dock loading and unloading, urban streets, residences, barns, livestock houses, airport runways, etc. It can also be used as auxiliary equipment for large-scale engineering construction machinery.

[0003] At present, the existing skid steer loaders are mainly used in the construction industry to dig sand and soil, and then load it into trucks or spread it flat on uneven ground for foundation consolidation. However, since the sand and soil have a certain humidity after rain or due to the humidity of the surrounding environment, the wet sand and soil are easily adhered to the bucket during the process of digging and dumping the sand and soil, which makes it difficult to remove the sand and soil on the bucket. It requires manual cleaning many times, which is labor-intensive. At the same time, the bucket mainly discharges the material by relying on the flipping of the bucket and the gravity of the sand itself, and the unloading efficiency is low. In addition, when paving the road surface to consolidate the foundation, quantitative unloading cannot be achieved well, resulting in the need for manual material leveling by tools many times in the later stage. The applicability is poor and cannot meet the actual use requirements.

[0004] Therefore, it is necessary to provide an automatic and efficient unloading device for a skid steer loader to solve the above problems. Summary of the Invention

The elastic pawl 26 is slidably connected to the inner shaft 23 through a limiting slide rod 47. A reset spring 48 is provided at the connection between the elastic pawl 26 and the inner shaft 23. The elastic pawl 26 is adapted to be movably connected to one side of the ratchet ring 25.

[0050] Furthermore, the unloading control mechanism also includes a worm gear 29, a worm 30 and a motor 31 for driving the inner shaft 23 to rotate. The middle part of the inner shaft 23 is fixedly connected to the worm gear 29, and the worm 30 is meshedly connected to the worm gear 29. The worm 30 is rotatably installed on the bucket 2. The worm 30 is fixedly connected to the output shaft of the motor 31, and the motor 31 is fixedly installed on the outside of the bucket 2 through the motor mounting box 10.

[0051] Furthermore, the material discharge control mechanism also includes a dividing knife 22 for dividing the material. The dividing knife 22 is fixedly installed inside the feed seat 18 through a fixed plate 21. The feed seat 18 is provided with a feed port 19 for feeding and a material guide slope 20 for guiding the material. The material guide slope 20 is inclined toward the feed port 19.

[0052] Furthermore, the scraper conveying mechanism also includes a driven roller 14 and an active roller 15 for driving the conveying steel belt 13 to perform material transmission. The driven roller 14 and the active roller 15 are both rotatably installed inside the bucket 2. The conveying steel belt 13 is transmission-connected to the driven roller 14 and the active roller 15. The active roller 15 is rotationally connected to the inner shaft 23 through the first synchronous belt 35.

[0053] Furthermore, the scraper conveying mechanism also includes a material guide slope 11 for connecting the material guide at the front end of the bucket 2. The material guide slope 11 is fixedly connected to the bucket 2. The first scraper plate 12 is fixedly connected to the material guide slope 11 and is arranged close to the upper plane of the conveyor steel belt 13. The second scraper plate 17 is fixedly connected to the material conveying seat 18 and is arranged close to the upper plane of the conveyor steel belt 13. The bucket 2 is also provided with a number of bucket teeth 9 for shoveling materials.

[0054] Furthermore, the first telescopic cylinder 3 is hingedly mounted on the loader body 1, the piston rod of the first telescopic cylinder 3 is rotatably mounted on the second connecting arm 5, the second connecting arm 5 is movably mounted at one end of the first connecting arm 4, the other end of the first connecting arm 4 is rotatably mounted on the loader body 1, and the second connecting arm 5 is rotatably mounted on the bucket 2 through the third connecting seat 49.

[0055] Furthermore, the second telescopic cylinder 6 is rotatably mounted on the second connecting arm 5 through the first connecting seat 7 , the piston rod of the second telescopic cylinder 6 is rotatably mounted on the second connecting seat 8 , and the second connecting seat 8 is fixedly mounted on the outer side of the bucket 2 .

[0056] Preferably, when the loader body 1 is performing the sand excavation operation, the bucket 2 is lifted and flipped by the movement of the loader body 1 and the control of the first telescopic cylinder 3 and the second telescopic cylinder 6, and the excavated sand enters the interior of the bucket 2. When the excavated sand needs to be dumped onto the truck, the first telescopic cylinder 3 and the second telescopic cylinder 6 are used for flipping control. In order to better unload and clean the material, the output shaft of the motor 31 drives the worm 30 to rotate, and the inner shaft 23 in the outer shaft 24 is driven to rotate counterclockwise under the relationship of the meshing connection between the worm 30 and the worm gear 29. Under the relationship of the elastic pawl 26 contacting and connecting with the ratchet ring 25, the elastic pawl 26 on the inner shaft 23 is pressed down and moved under the elastic action of the return spring 48. Since the outer shaft 24 is rotatably installed in the feed seat 18, the inner shaft 23 is rotatably installed on the bucket 2, so that the rotation of the inner shaft 23 cannot drive the outer shaft 24 to rotate. At this time, the first auger blade 27 and the second auger blade 28 are in a stationary state.

[0057] The rotation drive of the inner shaft 23 drives the active roller 15 to rotate under the synchronous driving action of the first synchronous belt 35, thereby driving the conveyor steel belt 13 to rotate counterclockwise under the transmission connection relationship between the driven roller 14, the active roller 15 and the conveyor steel belt 13, thereby facilitating the further transportation of the sand and soil in the bucket 2, realizing better unloading processing of the bucket 2, and while the conveyor steel belt 13 is conveying, the first scraper 12 on one side can well complete the scraping operation on the conveyor steel belt 13, and a heating rod 16 for heating is provided inside the conveyor steel belt 13, so that the wet sand and soil remaining on the conveyor steel belt 13 can be dried, which greatly reduces the wet sand and soil remaining inside the bucket 2, and does not require manual cleaning multiple times, with good cleaning effect and high degree of automation.

[0058] The continuous feeding method of the conveyor steel belt 13 in the bucket 2 can quickly complete the unloading task of sand and soil, reduce operation time and labor costs, avoid the problem of sand retention or spillage that may occur in the unloading process of the traditional bucket 2, thereby significantly improving the working efficiency, and the scraper and other components set can well remove the sand residue on the conveyor steel belt 13, so that the surface of the conveyor steel belt 13 is cleaner and smoother, which is convenient for subsequent feeding processing, and through the heating and drying treatment of the set heating rod 16, the excess water in the wet sand is effectively removed, so that the density and strength of the sand are improved. This optimized sand is more suitable for application scenarios that require high strength and stability, such as building foundation backfill, road paving, etc. At the same time, dry sand is easier to handle and transport, reducing construction difficulty and cost, and improving the overall construction quality and efficiency.

[0059] When it is necessary to perform quantitative unloading and paving operations on uneven roads, the output shaft of the motor 31 is driven in the reverse direction. At this time, the inner shaft 23 rotates clockwise to be connected to the inside of the outer shaft 24, so that the outer shaft 24 is driven to rotate clockwise under the relationship between the elastic pawl 26 and the ratchet ring 25, thereby driving the first auger blade 27 and the second auger blade 28 on the outer shaft 24 to rotate and drive, so as to facilitate the quantitative unloading of the sand and soil entering the feeding seat 18. Correspondingly, since the inner shaft 23 is in the clockwise rotation at this time, state, thereby correspondingly driving the conveyor belt 13 in the bucket 2 to transmit in a clockwise direction, so as to facilitate the continuous transmission of the sand in the bucket 2 to the feed port 19 on the feed seat 18, and the second scraper 17 can correspondingly clean the conveyor belt 13, so as to facilitate better unloading operation at the discharge pipe 46 on the feed seat 18. This quantitative unloading method can greatly reduce the number and error of manual operations in the later stage, realize a fast and continuous unloading process, so as to meet the needs of different construction, further shorten the construction period, and thus improve construction efficiency.

[0060] It should be noted that the number of the elastic pawls 26 is between 3 and 6, and the active roller 15 and the inner shaft 23 are both provided with pulleys that are synchronously connected to the first synchronous belt 35 .

[0061] Example 2

[0062] like Figures 1 to 14 As shown, based on Example 1, this embodiment further includes a vibration unloading mechanism, which is installed on the side of the bucket 2 and is used to perform vibration unloading control on the bucket 2. The vibration unloading mechanism includes a rotating rod 42 and a second impact ball 44 for vibration unloading control connection. The number of the second impact balls 44 is several and they are all fixedly installed on the side of the bucket 2. The rotating rod 42 is rotatably installed on the side of the bucket 2 through the second connecting shaft 41. The rotating rod 42 is provided with a first impact ball 43 for impacting the second impact ball 44.

[0063] Furthermore, the vibration unloading mechanism also includes a movable tooth plate 36 and a rotating gear 38 for driving the first impact ball 43 to rotate. The second connecting shaft 41 is rotatably connected to the first connecting shaft 39 through the second synchronous belt 40. The first connecting shaft 39 is rotatably installed on the outside of the bucket 2. The first connecting shaft 39 is fixedly connected to the rotating gear 38. The rotating gear 38 is meshed and connected to the movable tooth plate 36. The movable tooth plate 36 is slidingly connected to the loader body 1 through the guide slide 37. A sound insulation cover 45 for sound insulation protection connection is provided on the outside of the movable tooth plate 36.

[0064] Furthermore, the vibration unloading mechanism also includes a turntable 32 and a moving frame 34 for driving the moving tooth plate 36 to move back and forth. The turntable 32 is fixedly connected to both ends of the inner shaft 23, and the moving frame 34 is fixedly connected to one end of the moving tooth plate 36. The turntable 32 is provided with a guide column 33 that is adapted to be slidably connected to the moving frame 34.

[0065] Preferably, in this embodiment, no matter the motor 31 is driven to rotate forward or reverse, it will correspondingly drive the turntable 32 on the inner shaft 23 to rotate forward and reverse, thereby driving the movable tooth plate 36 to move back and forth on the guide slide 37 under the relationship of adaptive sliding connection between the guide column 33 and the movable frame 34 on the turntable 32. Due to the reciprocating movement of the movable tooth plate 36, the first connecting shaft 39 on the rotating gear 38 is driven to rotate. The first connecting shaft 39 drives the rotating rod 42 on the second connecting shaft 41 to rotate reciprocatingly under the synchronous driving action of the second synchronous belt 40. At this time, under the relationship of contact connection between the first impact ball 43 and the second impact ball 44 on the rotating rod 42, the side of the bucket 2 can be driven to perform reciprocating vibration operation, thereby further improving the unloading operation in the bucket 2.

[0066] This synchronous reciprocating vibration of the side of the bucket 2 can more effectively break the adhesion and accumulation of sand and soil, especially when dealing with sticky soil, wet sand or materials containing a large amount of water. This vibration can significantly enhance the thoroughness and efficiency of unloading. It also helps to reduce sand residue, improve the fluidity of sand, and make it more smoothly discharged from the bucket 2, which significantly improves the work efficiency of unloading. In addition, a corresponding sound insulation cover 45 is provided on the outside of the bucket 2, which further reduces noise pollution and facilitates work use.

[0067] It should be noted that both the first connecting shaft 39 and the second connecting shaft 41 are provided with pulleys that are synchronously connected to the second synchronous belt 40 .

[0068] It should be noted that the components in this application are all universal standard parts or components well known to those skilled in the art, which effectively solve the technical problems raised in the background technology.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
