Two circular sliding holes 442 are formed in the sleeve plate 436 at positions corresponding to the two support sliding rods 441. The two support sliding rods 441 are respectively slidably connected in the corresponding circular sliding holes 442.

[0033] Refer to Figure 1 , Figure 4 and Figure 5 , the lifting part 45 includes rectangular sliding plates 451 respectively arranged on the lower sides of the left and right ends of each rectangular mounting plate 41. The rectangular sliding plates 451 are slidably connected to the corresponding mounting vertical plates 31. Hydraulic push rods two 452 are rotatably penetrated and installed at the front and rear symmetry of the upper ends of the rectangular sliding plates 451. A plurality of roller two 453 are evenly installed at positions between the two hydraulic push rods two 452 at the lower ends of the rectangular sliding plates 451. The plurality of roller two 453 are all in rolling contact with the corresponding support top plates 2. The telescopic ends of the rear plurality of hydraulic push rods two 452 are respectively fixedly connected to the rectangular sliding plates 451. The telescopic ends of the front plurality of hydraulic push rods two 452 are respectively fixedly connected with auxiliary pressing plates 454. And retaining plates 455 are jointly installed at the opposite ends of the left and right rectangular mounting plates 41 and the opposite ends of the middle two auxiliary pressing plates 454.

[0034] Refer to Figure 1 , Figure 2 and Figure 6, the spiral conveyor mechanism 5 includes a material guiding bin 51 provided in the middle of the left and right supporting top plates 2. A material guiding elbow 52 is connected to the lower end of the material guiding bin 51. A conveying tank 53 is installed at one end of the material guiding elbow 52 away from the material guiding bin 51. A spiral conveying part 54 is provided on the conveying tank 53. The spiral conveying part 54 includes a feeding port 541 opened on the right end of the conveying tank 53 corresponding to the material guiding elbow 52. A second transmission shaft 542 is rotatably installed on the inner wall of the left end of the conveying tank 53. The right end of the second transmission shaft 542 rotatably penetrates through the material guiding elbow 52. A second motor 543 is installed through the right connecting vertical plate 62.

And spiral blades 544 are installed on the outer walls of the parts of the second transmission shaft 542 located in the conveying tank 53 and the material guiding elbow 52.

[0035] It should be noted that multiple second hydraulic push rods 452 are initially in the extended state, and the left and right rectangular mounting plates 41 are initially located above the frontmost protective plates 372. When the conveyor belt 33 drives the bulk materials to be continuously conveyed to the left, control the multiple second hydraulic push rods 452 to drive the left and right rectangular mounting plates 41 and the multiple auxiliary pressing plates 454 to move downward to a position where they are in contact with the left and right supporting top plates 2. At this time, the frontmost multiple protective plates 372 are respectively retracted into the corresponding rectangular mounting grooves 371. Then, control the right first transmission shaft 431 to rotate through the first motor 435. The right first transmission shaft 431 drives the intermediate shaft 432 to rotate synchronously through the second transmission belt 433. The intermediate shaft 432 drives the left first transmission shaft 431 to rotate synchronously and reversely through two transmission gears 434. At this time, the left and right first transmission shafts 431 rotate synchronously and reversely. The left and right first transmission shafts 431 respectively drive the corresponding sleeve plates 436 to rotate. The left and right sleeve plates 436 respectively drive the corresponding two connecting plates 440 to rotate through the corresponding multiple supporting slide rods 441. The two connecting plates 440 on the left and right sides respectively drive the corresponding rectangular sliding seats 437 to rotate through the corresponding connecting rods 438. At this time, the multiple rectangular sliding seats 437 will respectively slide along the corresponding rectangular guiding chutes 42. During this period, the multiple supporting slide rods 441 will make adaptive sliding compensation along the corresponding circular sliding holes 442, so as to drive the corresponding rectangular material pushing plates 439 to move along the corresponding rectangular guiding chutes 42. And because the two rectangular material pushing plates 439 on the left and right sides are symmetrically arranged, at this time, the bulk materials on the left and right conveyor belts 33 will be intermittently pushed into the middle material guiding bin 51 by the multiple rectangular material pushing plates 439 and continue to fall into the material guiding elbow 52. Then, control the second transmission shaft 542 to drive the spiral blades 544 to rotate through the second motor 543. The spiral blades 544 will drive the bulk materials to be continuously conveyed to the left. The bulk material conveying mechanism 3, the continuous material pushing mechanism 4 and the spiral conveyor mechanism 5 cooperate, and can simultaneously and continuously push the bulk materials on the two conveying lines into the material guiding bin 51, and continue to drive the bulk materials to be evenly conveyed to the left by the spiral blades 544, and the conveying is stable and convenient.

[0036] Refer to Figure 2 , Figure 6 and Figure 7 , the chute position adjusting mechanism 7 includes an arc-shaped limit chute 71 opened on the outer wall of the lower end of the conveying tank 53, an arc-shaped installation chute 72 opened at the left end of the conveying tank 53, the arc-shaped installation chute 72 communicates with the arc-shaped limit chute 71, and a position adjusting part 73 is arranged on the arc-shaped installation chute 72. The position adjusting part 73 includes two left and right discharge ports 731 opened on the inner wall of the conveying tank 53, both the two left and right discharge ports 731 communicate with the arc-shaped installation chute 72, an arc-shaped sealing slide plate 732 is slidably installed in the arc-shaped installation chute 72, a circular through hole 733 is opened in the middle of the outer wall of the arc-shaped sealing slide plate 732, an annular support plate 734 is installed at the position corresponding to the circular through hole 733 on the lower end of the outer wall of the arc-shaped sealing slide plate 732, the annular support plate 734 is slidably connected in the arc-shaped limit chute 71, and the left end of the left connecting vertical plate 62 penetrates and installs a first hydraulic push rod 735, and the telescopic end of the first hydraulic push rod 735 is fixedly connected to the annular support plate 734.

[0037] Refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 , the chute lifting mechanism 8 includes a telescopic chute 81 installed at the lower end of the annular support plate 734, an annular plate 82 is installed on the lower side of the outer wall of the telescopic chute 81, a double-shaft motor two 83 is installed on the outer wall of the upper end of the conveying tank 53 at the position between the two left and right discharge ports 731 through a motor base, the front and rear output shafts of the double-shaft motor two 83 are respectively fixedly connected with wire winding drums 84, wire ropes 85 are wound on both the front and rear wire winding drums 84, and the ends of the front and rear wire ropes 85 far away from the wire winding drums 84 are respectively fixedly connected to the annular plate 82.

[0038] It should be noted that the telescopic chute 81 is initially located above the left front side of the cargo ship's hold and is connected to the left discharge port 731. When the spiral blade 544 drives the bulk material to continuously convey to the left, the double-shaft motor two 83 controls the rotation of the front and rear wire winding drums 84. The front and rear wire winding drums 84 respectively drive the telescopic chute 81 to move downward to the bottom side position of the cargo ship's hold through the corresponding steel wire ropes 85. When the spiral blade 544 drives the bulk material to continuously convey to the left to the left discharge port 731, the bulk material will be discharged from the telescopic chute 81 to the bottom of the cargo ship's hold. As the height of the bulk material loaded onto the ship gradually increases, the double-shaft motor two 83 is controlled to drive the front and rear wire winding drums 84 to rotate in the reverse direction, so that the telescopic chute 81 can be jointly driven by the corresponding steel wire ropes 85 to slowly move upward. When the left front side position of the cargo ship's hold is filled with bulk material, the hydraulic push rod one 735 is controlled to drive the annular support plate 734 to move to the right. The annular support plate 734 will drive the arc-shaped sealing slide plate 732 to slide to the right along the arc-shaped installation chute 72 until the telescopic chute 81 is connected to the right discharge port 731. Once again, the double-shaft motor two 83 is controlled to drive the front and rear wire winding drums 84 to rotate. The front and rear wire winding drums 84 respectively drive the telescopic chute 81 to move downward to the bottom side position of the cargo ship's hold through the corresponding steel wire ropes 85, and the loading work on the right front side position of the cargo ship's hold can be continued. The bulk material will fall into the telescopic chute 81 from the right discharge port 731 and be discharged to the bottom of the cargo ship's hold. As the height of the bulk material loaded onto the ship gradually increases, the double-shaft motor two 83 is controlled to drive the front and rear wire winding drums 84 to rotate in the reverse direction, so that the telescopic chute 81 can be jointly driven by the corresponding steel wire ropes 85 to slowly move upward. The spiral conveying mechanism 5, the chute position adjusting mechanism 7 and the chute lifting mechanism 8 cooperate to conveniently control the left and right movement of the telescopic chute 81, so as to achieve the effect of freely adjusting the left and right positions of the cargo ship's hold during the bulk material loading process, without the need to turn the telescopic chute 81 and then adjust the front and rear positions to achieve the adjustment effect. The operation is convenient and fast, and the working cost is effectively reduced.

[0039] Refer to Figure 1 、 Figure 2 and Figure 6 As shown in, the traveling mechanism 6 includes a bottom plate 61 arranged on the lower side of the conveying tank 53. A plurality of connecting vertical plates 62 are uniformly installed at the upper end of the bottom plate 61. The conveying tank 53 penetrates through the left and middle connecting vertical plates 62 at the same time. The upper ends of the right and middle connecting vertical plates 62 are respectively slidably attached to the corresponding support top plates 2. Two front and rear rollers one 63 are respectively rotatably penetrated and installed at the lower end of the bottom plate 61 corresponding to the positions of the plurality of connecting vertical plates 62. Two front and rear rotating shafts 64 are rotatably penetrated and installed at the rear end of the bottom plate 61. The two front and rear rotating shafts 64 are connected by a first transmission belt 65. A forward and reverse motor 66 is commonly installed on the bottom plate 61 and the right connecting vertical plate 62 through a motor seat. The output shaft of the forward and reverse motor 66 is fixedly connected to any one of the rotating shafts 64.

[0040] When the front right side position of the cargo ship's hold is filled with bulk materials, control the double-axis motor 1 to stop working. At the same time, control multiple hydraulic push rods 2 to drive the left and right rectangular mounting plates 1 and multiple auxiliary pressing plates 4 upward to return to their original positions. At this time, the frontmost multiple protective plates 2 will respectively protrude from the corresponding rectangular mounting grooves 1. Then, control the rotation of the rotating shaft 4 connected by the forward and reverse motor 6. This rotating shaft 4 drives another rotating shaft 4 to rotate synchronously through the first transmission belt 5. The front and rear rotating shafts 4 respectively drive multiple first rollers 3 to rotate. The multiple first rollers 3 together drive the multiple connecting vertical plates 2 to move backward through the bottom plate 1. At this time, the multiple connecting vertical plates 2 will drive the conveying tank 3, the material guiding bin 1, and the material guiding elbow 2 to move backward. The material guiding bin 1 will drive the corresponding two rectangular sliding plates 4 to move backward. During this period, the left and right rectangular mounting plates 1 and the multiple auxiliary pressing plates 4 will also move backward accordingly, and the multiple second rollers 3 will roll adaptively along the corresponding supporting top plates 2. When the left and right rectangular mounting plates 1 and the multiple auxiliary pressing plates 4 move backward to the upper side position of the multiple adjacent rear protective plates 2, control the forward and reverse motor 6 to stop working, and control multiple hydraulic push rods 2 to drive the left and right rectangular mounting plates 1 and the multiple auxiliary pressing plates 4 to move downward to a position where they are in contact with the left and right supporting top plates 2. At this time, the telescopic chute 1 is above the rear position of the bulk materials piled up in the cargo ship's hold. Repeat the above adjustment operations of the chute height and position and the adjustment steps of the position of the conveying tank 3 to complete the work of filling the cargo ship's hold with bulk materials. When the loading of the cargo ship's hold is completed, control the double-axis motor 1 and the second motor 3 to stop working.

[0041] Repeat the above operations to repeat the loading work of the cargo ship's hold. The bulk material conveying mechanism 3, the continuous material feeding mechanism 4, the traveling mechanism 6, the screw conveying mechanism 5, the chute position adjustment mechanism 7, and the chute lifting mechanism 8 cooperate to convey bulk materials simultaneously using two conveying lines, which can prevent leakage during the conveying process. By continuously pushing the bulk materials on the two conveying lines into the material guiding bin 1 at the same time and continuing to evenly convey the bulk materials to the left along the conveying tank 3, the conveying is stable and convenient, effectively improving the conveying efficiency. Moreover, it is possible to conveniently control the telescopic chute 1 to move in multiple directions of front-back, left-right, and up-down, so as to achieve the effect of freely adjusting the loading of bulk materials into the cargo ship's hold. There is no need for the telescopic chute 1 to turn first and then adjust the front-back position to achieve the adjustment effect. While improving the loading efficiency, the structure is compact, reducing the floor space, and effectively reducing the manufacturing cost.
