DETAILED DESCRIPTION

[0031] 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 embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] This specific embodiment is a lifting type tooth fork roller conveyor, and its structural diagram is as follows Figure 1-Figure 7 As shown, it includes a base frame 1, brackets 2 installed on both sides of the base frame 1, a roller group 3 installed on the base frame 1, and a driving motor 4 for driving the roller group 3 to rotate;

[0033] The roller group 3 includes a main roller group 301 rotatably mounted on one side of the base frame 1, a middle roller group 302 rotatably mounted in the middle of the base frame 1, and a slave roller group 303 rotatably mounted on the other side of the base frame 1.

[0034] The driving motor 4 drives the main roller group 301 to rotate and can drive the material placed on the lifting fork roller conveyor to move, and when the material moves, it drives the middle roller group 302 and the slave roller group 303 to rotate, so that the middle roller group 302 and the slave roller group 303 can cooperate with the main roller group 301 to move the material;

[0035] A lifting mechanism 5 for lifting the base frame 1 is provided between the base frame 1 and the bracket 2. A pull rod 6 for increasing the strength of the base frame 1 is fixedly installed at the bottom of the base frame 1. A transition roller 7 for smooth transition is installed on the two brackets 2, and an adjustment mechanism 8 for adjusting the height of the transition roller 7 is installed on the bracket 2.

[0036] A guide mechanism 9 is provided inside the bracket 2 to guide the lifting and lowering of the base frame 1. The drive motor 4 and the guide mechanism 9 are both installed on the lifting mechanism 5, and the drive motor 4 is installed vertically. When the drive motor 4 is installed vertically, a gap is left between it and the guide mechanism 9 to avoid mutual interference.

[0037] When the staff pushes the ground ox to load materials onto the chassis 1, the chassis 1 and the materials on the chassis 1 are driven to rise through the lifting mechanism 5. During the rising process of the chassis 1, the guide mechanism 9 guides the movement of the chassis 1, so that the chassis 1 will not deviate during the rising process.

[0038] The driving motor 4 drives the main roller group 301 to rotate in the existing technology, for example: Figure 1 and Figure 7As shown, a main sprocket is fixedly connected to the output end of the driving motor 4, and two sprockets are fixedly connected to one end of each rotating roller on the main roller group 301. The sprockets on the two adjacent rotating rollers are driven by chains, and the adjacent chains are installed in a staggered manner. The main chain is installed on the sprockets on the two adjacent rotating rollers and the main sprocket. When the output end of the driving motor 4 drives the main sprocket to rotate, the main sprocket drives the two sprockets to rotate through the main chain, and the rotating rollers on the entire main roller group 301 are rotated under the action of the chain.

[0039] In some embodiments, as Figure 4 As shown, there are multiple tie rods 6, and the multiple tie rods 6 are distributed at equal intervals. The tie rods 6 include but are not limited to 12 mm plates. Through the arrangement of the tie rods 6, the grooves of the base frame 1 for installing the roller group 3 are supported, thereby improving the overall strength of the base frame 1.

[0040] In some embodiments, as Figure 1 、 Figure 2 and Figure 5 As shown, the adjustment mechanism 8 includes an L-shaped plate 801 fixedly mounted on the bracket 2, a mounting bracket 802 mounted on the L-shaped plate 801, and a screw 803 for adjusting the height of the mounting bracket 802. The transition roller 7 is rotatably mounted on the two mounting brackets 802. One end of the L-shaped plate 801 is fixedly mounted on the bracket 2. A threaded hole that matches the screw 803 is opened in the middle of the other end of one end of the L-shaped plate 801. The screw 803 is threadedly connected to the L-shaped plate 801 through the threaded hole. The top end of the screw 803 is rotatably connected to the bottom of the mounting bracket 802 through a bearing.

[0041] By rotating the screw 803 clockwise, the screw 803 is moved upward under the action of the threaded hole opened in the L-shaped plate 801, and the screw 803 can drive the mounting frame 802 to move upward when moving upward, and the mounting frame 802 can drive the transition roller 7 to move upward during the movement. Similarly, by rotating the screw 803 counterclockwise, the transition roller 7 can be moved downward, so that the transition roller 7 has the advantage of adjustable height, so that the height of the transition roller 7 can be adjusted according to the actual material, and the material can be smoothly transferred under the action of the transition roller 7;

[0042] A slide groove 8021 is provided on one side of the mounting frame 802. A slide rod 8022 that cooperates with the slide groove 8021 is fixedly mounted on one end of the L-shaped plate 801. The slide rod 8022 is slidably connected to the interior of the slide groove 8021. The protruding end of the slide rod 8022 extends to the exterior of the mounting frame 802. A small gap, for example 2 mm, is left between the protruding end of the slide rod 8022 and the mounting frame 802, thereby facilitating the movement of the mounting frame 802.

[0043] Through the cooperation of the slide groove 8021 and the slide rod 8022, the mounting frame 802 can not only move up and down following the screw rod 803, but also guide the movement of the mounting frame 802, so that the mounting frame 802 moves more smoothly, thereby making the transition roller 7 installed on the mounting frame 802 move more smoothly.

[0044] In some embodiments, as Figure 1 、 Figure 2 and Figure 3 As shown, two lifting mechanisms 5 are provided, and the two lifting mechanisms 5 are respectively located on both sides of the base frame 1. Each lifting mechanism 5 includes a plurality of pulleys 501, and the plurality of pulleys 501 are rotatably mounted on the bracket 2. Belts 502 are driven and installed on the plurality of pulleys 501, and a connecting plate 503 is fixedly mounted on the end of the belt 502. The connecting plate 503 is fixedly connected to the base frame 1. A same rotating shaft 504 is fixedly connected between the pulleys 501 located outside the bracket 2 of the two lifting mechanisms 5, and a lifting motor 505 is fixedly connected to the end of the rotating shaft 504.

[0045] Starting the lifting motor 505 drives the rotating shaft 504 to rotate clockwise, and the rotating shaft 504 can drive the pulleys 501 on the two lifting mechanisms 5 fixedly connected to it to rotate. When the pulley 501 rotates, the driving belt 502 moves. When the belt 502 moves, it drives the connecting plate 503 to move upward. During the upward movement, the connecting plate 503 can drive the base frame 1, the driving motor 4 and the guide plate 902 to move upward. Similarly, starting the lifting motor 505 drives the rotating shaft 504 to rotate counterclockwise, so that the base frame 1, the driving motor 4 and the guide plate 902 move downward.

[0046] In some embodiments, as Figure 1 、 Figure 2 and Figure 3 As shown, the drive motor 4 is fixedly mounted on the connecting plate 503, and the drive motor 4 is installed vertically;

[0047] The guide mechanism 9 includes a guide rod 901 fixedly connected to the bottom of the bracket 2, a guide plate 902 fixedly mounted on the top of the connecting plate 503, and guide wheels 903 slidingly contacting the two sides of the guide rod 901. The guide wheels 903 are rotatably mounted on the guide plate 902, and a gap is left between the guide plate 902 and the drive motor 4.

[0048] Since the space on the connecting plate 503 is limited, the guide plate 902 occupies a large space after being installed. Therefore, the drive motor 4 is installed vertically. Compared with the horizontal installation, this can save the installation space of the drive motor 4, so that the drive motor 4 and the guide plate 902 do not interfere with each other after being installed on the connecting plate 503.

[0049] In some embodiments, as Figure 2 and Figure 3 As shown, when the guide plate 902 follows the connecting plate 503 to move up and down, the guide plate 902 drives the guide wheel 903 to roll on the guide rod 901, so that the movement of the guide plate 902 can be guided by the cooperation of the guide wheel 903 and the guide rod 901, so that the movement of the guide plate 902 is more stable. Since the connecting plate 503 is fixedly connected to the guide plate 902 and the connecting plate 503 is also fixedly connected to the base frame 1, the movement of the base frame 1 is guided by the action of the guide mechanism 9.

[0050] In some embodiments, as Figure 2 As shown, the middle part of the guide rod 901 is fixedly installed on the middle part of the bracket 2 through an L-shaped bracket, and the limiting blocks 9011 are fixedly connected on both sides of the upper end of the guide rod 901. Through the setting of the limiting blocks 9011, the maximum upward rolling distance of the guide wheel 903 on the guide rod 901 is limited, preventing the guide wheel 903 from separating from the guide rod 901.

[0051] In some embodiments, as Figure 3 As shown, a ramp 101 is formed between the middle roller group 302 and the main roller group 301, and between the middle roller group 302 and the slave roller group 303. A ramp plate 102 connected to the ramp 101 is fixedly installed at the front end of the base frame 1. The ramp plate 102 includes an inclined plate 1021 and a horizontal plate 1022 fixedly connected to the inclined plate 1021. The horizontal plate 1022 is coplanar with the ramp 101.

[0052] Under the action of the inclined plate 1021 , the cattle can easily enter the ramp plate 102 , and under the setting of the horizontal plate 1022 , the cattle can easily enter the ramp 101 . Under the setting of the ramp 101 , the cattle can easily be inserted into the base frame 1 .

[0053] In some embodiments, as Figure 6 As shown, the commonly used pallet height is 144 mm, and the height between the highest position on both sides of the conventional chassis 1 and the ramp 101 is H (as shown in FIG. Figure 6 As shown), and H is greater than 144mm, so it will cause interference when placing the pallet. In order to avoid the above interference, the height adjustment between the ramp 101 of the present application and the highest position on both sides of the base frame 1 is reduced to less than 144mm, so that no interference will occur.

[0054] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
