Description

Technical Field

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

[0002] A skid steer loader, also known as a slip-type loader, a multi-functional engineering vehicle, or a multi-functional engineering machine, is a wheeled special chassis equipment that utilizes 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 then load it into trucks or spread it on uneven ground for foundation consolidation. However, due to the sand having a certain humidity after rain or due to the humidity of the surrounding environment, the wet sand is easily adhered to the bucket during the process of digging and dumping the sand, which makes it difficult to remove the sand on the bucket and requires manual cleaning many times, which is labor-intensive. At the same time, the bucket is mainly unloaded 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, the quantitative unloading process cannot be well achieved, 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.

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 wheel 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 with the worm wheel 29, and the worm 30 is meshingly connected to the worm wheel 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, and the dividing knife 22 is fixedly installed inside the material conveying seat 18 through a fixing plate 21. The material conveying seat 18 is provided with a feed port 19 for feeding and a material guiding slope 20 for guiding the material, and the material guiding 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 for 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 used 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, and the bucket 2 is also provided with a plurality of bucket teeth 9 for scraping 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 turned over 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 turning control, and for better material unloading and cleaning, 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 meshing connection between the worm 30 and the worm wheel 29. Under the contact connection between the elastic pawl 26 and 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, and the inner shaft 23 is rotatably installed on the bucket 2, 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, so as to facilitate the further transportation of the sand in the bucket 2, and realize better unloading processing of the bucket 2. While the conveyor steel belt 13 is conveying, the first scraper plate 12 on one side can well complete the scraping operation on the conveyor steel belt 13, and the interior of the conveyor steel belt 13 is provided with a heating rod 16 for heating, so that the wet sand remaining on the conveyor steel belt 13 can be dried, which greatly reduces the wet sand remaining in the interior of the bucket 2, and does not need to be manually cleaned 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 the operation time and labor cost, 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 the 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, which reduces the construction difficulty and cost, and improves 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, and the inner shaft 23 is rotated 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 of the elastic pawl 26 and the ratchet ring 25 in contact and connection, 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, and correspondingly, since the inner shaft 23 is in a clockwise rotation at this time, state, thereby correspondingly driving the conveyor belt 13 in the bucket 2 to drive and convey in a clockwise direction, so as to continuously convey the sand in the bucket 2 to the feed port 19 on the feed seat 18, and the second scraper plate 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 well 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 constructions, further shorten the construction period, and thus improve the construction efficiency.

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

[0061] Example 2

[0062] like Figure 1 to Figure 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 connected for vibration unloading control. 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 that is adapted to be connected.

[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 rotationally 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 meshingly connected to the movable tooth plate 36. The movable tooth plate 36 is limitedly slidably 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 the present 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 reciprocate on the guide slide plate 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 is driven to reciprocate the rotating rod 42 on the second connecting shaft 41 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 accordingly, thereby further improving the unloading operation in the bucket 2.

[0066] This synchronous reciprocating vibration mode 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, while also helping to reduce sand residue and improve the fluidity of sand, so that it can be discharged more smoothly from the bucket 2, significantly improving the work efficiency of unloading, and a corresponding sound insulation cover 45 is provided on the outside of the bucket 2, thereby further reducing noise pollution and facilitating work use.

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

[0068] It should be particularly 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.
