Description

Technical Field

[0001] This invention relates to the field of bulk material handling and transfer technology, and in particular to a multifunctional bulk material handling machine. Background Technology

[0002] In various scenarios requiring bulk cargo transfer, such as material yards, warehouses, and ship holds, the operational efficiency and functional adaptability of bulk material handling and transfer directly impact overall production flow efficiency. Currently, the mainstream bulk material transfer equipment on the market is mainly loaders or belt conveyors. These types of equipment generally have the limitation of single-function operation. Loaders are mostly used for shoveling and short-distance transfer of bulk materials, while belt conveyors are mainly used for long-distance continuous material transport. After the material transfer operation is completed, the remaining bulk materials on the site require additional specialized cleaning equipment for sweeping, resulting in the need for multiple machines to work together in the entire operation.

[0003] The aforementioned multi-equipment, multi-tasking operation mode not only increases equipment investment costs but also requires multiple operators to control different devices, raising labor costs. Furthermore, the time lag between equipment operations leads to low overall operational efficiency. Therefore, there is an urgent need to design a multi-functional integrated bulk material handling machine to streamline operations, reduce labor and time costs, and improve adaptability to different scenarios, thereby meeting the demands of modern operations for efficient, integrated, and flexible bulk material handling and transportation.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] This invention discloses a multifunctional bulk material handling machine.

[0028] Reference Figures 1 to 3 A multi-functional bulk material handling machine includes a main body 1, a cab 2, a power system 3, a walking system 4, a feeding and conveying system 5, a working arm 6, and a cleaning system 7. The main body 1 adopts a high-strength frame structure, providing a stable installation support foundation for each functional system. The cab 2, power system 3, walking system 4, feeding and conveying system 5, working arm 6, and cleaning system 7 are respectively mounted on the main body 1. The power system 3 provides power to the entire machine. The walking system 4 adopts a tracked walking structure, symmetrically located on both sides of the bottom of the main body 1. The cab 2 features a side-opening door design for easy operator access. A scissor-type lifting mechanism is installed between its bottom and the main body 1. The scissor structure is hydraulically driven to extend and retract, enabling vertical adjustment of the cab 2. Operators can adjust the height of the cab 2 according to operational needs, expanding their field of vision, controlling the feeding position, unloading point, and cleaning range, and reducing operational errors.

[0029] Reference Figure 4 and Figure 5 The feeding and conveying system 5 is the core unit for realizing the automatic transfer of bulk materials. It includes a feeding mechanism 51, a primary conveyor belt 53 and a secondary conveyor belt 54, which are connected in sequence to form a continuous material transfer channel. The feeding mechanism 51 is equipped with a hydraulic linkage mechanism 52, which consists of an upper linkage 521, a lower linkage 522, and an adjusting cylinder 523. The feeding base plate 511 of the feeding mechanism 51 has outer plates 514 fixed on both sides. The two ends of the upper linkage 521 are respectively hinged to the upper part of the outer plate 514 and the main body 1 of the vehicle body. The two ends of the lower linkage 522 are respectively connected to the lower part of the outer plate 514 and the main body 1 of the vehicle body. The upper linkage 521 is located above the lower linkage 522 and is arranged in parallel, forming a parallelogram structure. By adjusting the extension and retraction of the cylinder 523, the upper linkage 521 and the lower linkage 522 can be driven to move up and down synchronously, thereby driving the feeding mechanism 51 to move up and down as a whole. This allows for flexible adjustment of its contact height with the ground, adapting to different thicknesses of bulk material layers, ensuring sufficient feeding, and avoiding excessive friction between the feeding mechanism 51 and the ground.

[0030] Reference Figure 3The feeding mechanism 51 corresponds to the inlet end of the primary conveyor belt 53. The outlet end of the primary conveyor belt 53 is connected to the inlet end of the secondary conveyor belt 54 through a receiving hopper 545 to ensure automatic and continuous transfer of bulk materials. The receiving hopper 545 is fixed on the hopper at the inlet end of the secondary conveyor belt 54. The feeding mechanism 51 includes a feeding base plate 511, a left feeding impeller 512, and a right feeding impeller 513. The left feeding impeller 512 and the right feeding impeller 513 are symmetrically arranged above the feeding base plate 511. Driven by a motor or hydraulic motor, they rotate synchronously inward. The rotational thrust of the impellers quickly gathers the bulk materials accumulated on the feeding base plate 511 and transfers them to the primary conveyor belt 53, realizing automatic feeding of bulk materials without the need for manual assistance in pushing the materials.

[0031] Reference Figure 6 and Figure 7 The bottom of the feed end of the secondary conveyor belt 54 is hinged with a rotary support base 541, which is rotatably connected to the body 1 of the vehicle. The rotary support base can be driven to rotate by an electric motor or a hydraulic motor. The rotary support base 541 has a built-in mechanical limit structure and an electronic limit structure. The rotary support base 541 can drive the secondary conveyor belt 54 to swing 90° to the left and right, thereby expanding the unloading coverage area.

[0032] Reference Figure 3 A lifting cylinder 542 is also provided between the secondary conveyor belt 54 and the main body 1. The piston rod of the lifting cylinder 542 is hinged to an isosceles triangular plate 547, and the piston rod of the lifting cylinder 542 is connected to the middle of the isosceles triangular plate 547. Steel wire ropes 546 are connected to both ends of the isosceles triangular plate 547. The ends of the two steel wire ropes 546 away from the isosceles triangular plate 547 are connected to the outer wall of the middle part of the secondary conveyor belt 54. The end of the lifting cylinder 542 away from the secondary conveyor belt 54 is connected to the body system through a universal joint. With the help of the hydraulic extension and retraction action of the lifting cylinder 542, the secondary conveyor belt 54 can be driven to swing up and down. Combined with the left and right swing function of the slewing support base 541, the secondary conveyor belt 54 can be unloaded at fixed points at different heights and directions, which can meet the feeding needs of different receiving equipment such as silos and transport vehicles.

[0033] Reference Figure 6 and Figure 7The secondary conveyor belt 54 includes a cabin and a conveyor belt mechanism assembled inside the cabin. The cabin consists of a bottom cabin 543 and a front cabin 544. The end of the bottom cabin 543 away from the front cabin 544 is the feed end of the secondary conveyor belt 54. Its bottom is hinged to the slewing support base 541, and its upper part is fixedly connected to the receiving hopper 545. The end of the bottom cabin 543 away from the main body 1 is hinged to the front cabin 544. A hydraulic tilting linkage mechanism 55 is provided on the outer wall between the front cabin 544 and the bottom cabin 543. The hydraulic tilting linkage mechanism 55 consists of a first tilting cylinder 551, a tilting linkage 552, and a second tilting cylinder 553. One end of 551 is hinged to the outer wall of the bottom compartment 543, and the other end is hinged to the middle of the tilting link 552. One end of the tilting link 552 is hinged to the bottom compartment 543, and the other end is hinged to the piston rod of the second tilting cylinder 553. The end of the second tilting cylinder 553 away from the tilting link 552 is hinged to the outer wall of the front compartment 544. Through the coordinated extension and retraction of the first tilting cylinder 551 and the second tilting cylinder 553, the tilting link 552 can be driven to rotate, thereby driving the front compartment 544 to tilt downward. On the one hand, this facilitates the emptying of residual materials in the compartment, and on the other hand, it effectively reduces the overall length of the secondary conveyor belt 54, making transportation and movement easier.

[0034] Reference Figure 8 and Figure 9 The working arm 6 is used for feeding the material to the feeding mechanism 51 and for multi-scenario operations. It includes a bucket 61, a quick connector 62, a telescopic arm 63, a stick 64, a boom 65, a swing bracket 66, and a side-shifting bracket 67. The side-shifting bracket 67 is fixedly connected to the vehicle body 1. The side-shifting bracket 67 consists of two parallel guide rails 671 and a slide block 672 slidably connected to the guide rails 671. The two guide rails 671 are horizontally fixed to the vehicle body 1. The swing bracket 66 is hinged to the slide block 672 and can swing horizontally relative to the slide block 672. A transverse movement cylinder 673 is installed between the slide block 672 and the vehicle body 1. The cylinder body of the transverse movement cylinder 673 is fixed to the vehicle body 1, and its piston rod is connected to the slide block 672. The extension and retraction of the transverse movement cylinder 673 drives the slide block 672 to slide smoothly on the guide rails 671, thereby driving the working arm 6 to move horizontally left and right as a whole, expanding the operating coverage area. The boom 65 is hinged to the swing bracket 66, the stick 64 is hinged to the boom 65, and the telescopic boom 63 is telescopically nested inside the stick 64. The bucket 61 is detachably connected to the telescopic boom 63 via a quick connector 62. The working arm 6 can drive the bucket 61 to complete various actions such as raking, feeding, and digging by controlling the extension and retraction of the corresponding cylinders of each joint. When the feeding mechanism 51 is insufficient, the working arm 6 can control the bucket 61 to pick up material from the bulk pile and accurately transport it to the feeding base plate 511, ensuring continuous operation. At the same time, with the help of the quick connector 62, various working tools such as breakers and grabs can be easily replaced to adapt to the needs of multiple operation scenarios such as digging, crushing, and grabbing.

[0035] Reference Figure 1 The cleaning system 7 is located at the front end of the feeding mechanism 51, including a housing 71 and a roller brush 72 rotatably connected inside the housing 71. The housing 71 is connected to the feeding mechanism 51, and the cleaning operation is linked with the feeding operation. A cleaning drive component is installed on the housing 71. This cleaning drive component can be an electric motor or a hydraulic motor, which is used to drive the roller brush 72 to rotate at high speed. The bristles of the roller brush 72 are in close contact with the ground, which can efficiently sweep the loose material remaining on the ground after material transfer onto the feeding base plate 511, realizing the integration of cleaning and recycling. No additional cleaning equipment is required, which reduces the operation process, avoids material waste, and ensures the cleanliness of the site.

[0036] The top of the main body 1 is equipped with an automatic hook release device 8, whose hook has automatic locking and unlocking functions to adapt to the hoisting and traction needs of loading and unloading ships at the dock. The driving modes of this multi-functional bulk material handling machine include one or more of the following: in-vehicle manual driving, remote control driving, and remote remote control driving. Each driving mode can be flexibly switched according to the working scenario. In-vehicle manual driving is suitable for close-range precision operations, while remote control driving and remote remote control driving can meet the needs of operations in confined spaces and hazardous environments, further improving operational flexibility and safety.
