Description

Technical Field

[0001] The utility model belongs to the technical field of conveying equipment structures, in particular to the technical field of conveying and distributing material structures. Background Art

[0002] Current material distribution and conveying devices are mostly mobile vehicles, with a motor reducer driving the wheels in forward and reverse rotation, driving the vehicle back and forth. This type of material distribution and conveying device consists of a complex driving control system, travel switches, brakes, and buffers. The advantage is that it can achieve multi-station material distribution with more than two stations. The disadvantages are: system complexity and high cost, especially when distributing materials with fewer stations; the control system must be responsive, the travel switch signals must be accurate, and the brake system must be reliable. If any of these safety factors fails, it can lead to inaccurate positioning and material leakage at best, or even damage to the buffer and derailment. The brake pads and buffer anti-collision parts must be regularly replaced. Summary of the Invention

[0032] A conveying and distributing device includes an incoming material conveyor and a distributing hopper 5, wherein the device includes a frame 1, a distributing material conveyor 2, a connecting rod mechanism 3, and a driving device 4;

[0033] The material distribution conveyor 2 is arranged below the incoming material conveyor;

[0034] The material distribution conveyor 2 is movably arranged on the upper surface of the frame 1;

[0035] The driving device 4 is fixedly arranged on the frame 1;

[0036] The driving device 4 drives the material distribution conveyor 2 to move horizontally through the connecting rod mechanism 3.

[0037] Furthermore, the lower portion of the material distribution conveyor 2 of the present invention is provided with a traveling wheel 21; the upper surface of the frame 1 is provided with a guide rail 11; the traveling wheel 21 is arranged in the guide rail 11 to achieve horizontal movement.

[0038] Furthermore, the distribution conveyor 2 of the present invention is provided with a connecting support 22; the driving device 4 is connected to the connecting support 22 through the connecting rod mechanism 3, driving the distribution conveyor 2 to move horizontally.

[0039] Furthermore, the connecting rod mechanism 3 of the present invention includes a crank 31, an active connecting rod 32, a rocker rod 33, an auxiliary connecting rod 34, and a fixed support 35;

[0040] The crank 31 is fixedly connected to the output shaft of the driving device 4;

[0041] Two hinge points are respectively provided at both ends of the active connecting rod 32 to connect the crank 31 and the rocker 33; that is, one end of the active connecting rod 32 is hinged near the edge of the crank 31;

[0042] The rocker arm 33 is provided with three hinge points, located at both ends and near the end 1 / 3; one end of the rocker arm 33 is hinged to the fixed support 35; the other end of the rocker arm 33 is hinged to the auxiliary connecting rod 34; the hinge point near the end 1 / 3 of the rocker arm 33 is hinged to the other end of the active connecting rod 32;

[0043] Two hinge points are respectively provided at both ends of the auxiliary link 34 to connect the material distribution conveyor 2 and the swing arm 33; that is, one end of the auxiliary link 34 is hinged to the swing arm 33; the other end of the auxiliary link 34 is hinged to the material distribution conveyor 2;

[0044] The fixed support 35 is fixedly arranged on the frame 1 to ensure the movement trajectory of the rocker 33 .

[0045] Furthermore, the driving device 4 of the present invention may use a motor reducer as a power source, or may use a hydraulic motor or a pneumatic motor as a power source.

[0046] Furthermore, the present invention provides multiple groups of feed hoppers 5, which are arranged horizontally and sequentially in the direction of the reciprocating motion of the feed conveyor 2. The feed conveyor 2 includes a transmission belt mechanism, and the material conveying direction of the conveyor belt corresponds to the material receiving opening of the feed hopper 5. The feed hopper 5 is composed of an inverted "human" structure. The specific structure of the feed hopper can be determined according to the number of production lines set up for the downstream process. If the downstream process has two lines, the feed hopper 5 has a single inverted "human" shape with two hoppers. If the downstream process has three lines, the feed hopper 5 has an inverted "follower" shape with three hoppers.

[0047] When the utility model is implemented, Figure 1As shown, the material conveying and distributing device is in the left limit position, the hinge point A between the crank 31 and the active connecting rod 32 is in the left limit position of the driving device 4, and the connecting rod mechanism 3 is in the left limit position. At this time, the distributing conveyor 2 supplies materials to the lower process production line 1 through the left discharge port of the distributing hopper 5;

[0048] When the driving device 4 drives the crank 31 to rotate clockwise around point O1, the crank 31 outputs a pulling force, and the force acting on the active connecting rod 32 is a pulling force. The pulling force is transmitted to the hinge point B of the swing rod 33 through the active connecting rod 32. Under the action of the force, the swing rod 33 swings to the right with the fixed hinge point O2 as the center of the circle. At this time, the force is transmitted to the auxiliary connecting rod 34 through the hinge point C, and the auxiliary connecting rod 34 moves the material distribution conveyor 2 to the right;

[0049] like Figure 2 As shown, when the crank 31 rotates to the right extreme position, the hinge point A between the crank 31 and the active connecting rod 32 is at the right extreme position of the driving device 4, and the connecting rod mechanism 3 is at the right extreme position. At this time, the distribution conveyor 2 supplies materials to the lower process production line 2 through the right discharge port of the distribution hopper 5;

[0050] When the driving device 4 drives the crank 31 to continue to rotate clockwise around point O1, the crank 31 outputs thrust, and the force acting on the active connecting rod 32 becomes thrust, which is transmitted to the hinge point B of the rocker arm 33 through the active connecting rod 32. Under the action of the force, the rocker arm 33 swings to the left with the fixed hinge point O2 as the center of the circle. At this time, the force is transmitted to the auxiliary connecting rod 34 through the hinge point C, and the auxiliary connecting rod 34 moves the material distribution conveyor 2 to the left. When it reaches the left limit position, the output force of the crank 31 becomes thrust again, and this cycle is repeated to realize the function of the material distribution conveyor 2 to reciprocately feed the material distribution hopper 5.
