Description

Technical Field

[0001] The utility model is applied to the technical field of automated production lines, and particularly relates to a blocking structure and a feeding conveying line. Background Art

[0002] With the development of society and the improvement of people's living standards, people's demand for vegetables has gradually increased, and their requirements for the quality and taste of vegetables have become higher and higher. Based on the above situation, facility agriculture has emerged. The production environment of facility agriculture is closed, and the temperature and humidity are moderate, which can provide suitable conditions for the growth of vegetables. Vegetables are planted on planting strips through planting cups. The planting strips need to be stopped on the feeding conveyor line in order to complete a series of processes. Most of the existing stopping mechanisms adopt a straight up and down structure. The cylinder drives the baffle to move vertically upward, thereby stopping the planting strips of the conveyor line. For example, the Chinese patent with publication number CN211109807U discloses a conveyor line blocking mechanism. When the conveyor line reaches the predetermined position, the downward pressure part on the drive plate is pressed and drives the vertical rod downward, so that the block seat retracts into the conveying plane of the conveyor line. The stopping mechanism adopts a straight up and down structure. The objects on the conveyor line collide with the baffle for a long time. The position of the blocking mechanism is easily offset, thereby affecting the movement stroke and resulting in poor blocking effect. Therefore, it is necessary to provide a blocking structure and a feeding conveyor line with a simple structure, high positioning accuracy and buffering effect. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a blocking structure and a feeding conveying line which have a simple structure, high positioning accuracy and a buffering effect.

[0004] The technical solution adopted by the present invention is: the present invention includes a mounting frame, a mounting plate, a driving cylinder, two groups of first connecting rods, and two groups of second connecting rods. The mounting plate is arranged above the mounting frame, and the driving cylinder is rotatably connected to the bottom of the mounting frame. The tops of the two groups of first connecting rods are respectively hinged to the left end of the mounting plate, the bottoms of the two groups of first connecting rods are hinged to the mounting frame, the tops of the two groups of second connecting rods are respectively hinged to the right end of the mounting plate, the middle parts of the two groups of second connecting rods are respectively hinged to the mounting frame, the action end of the driving cylinder is hinged to the bottoms of the two groups of second connecting rods, and a baffle is provided on the top of the mounting plate.

[0005] It can be seen from the above scheme that the blocking structure has a buffering effect. When the planting strip hits the baffle, it is transmitted to the driving cylinder output rod through the connecting rod mechanism, and then the gas in the cylinder is squeezed, and the cylinder acts as a buffer. The present application uses a three-position five-way center-sealed solenoid valve to keep the protruding rod of the driving cylinder in the buffer position. The driving cylinder serves as the power source of the blocking structure and also serves as the buffer of the blocking structure. Compared with the straight up and down structure of the prior art, the blocking structure can avoid hard impact between the planting strip and the baffle, and at the same time has the advantages of high positioning accuracy, long-term work suitability, and no position displacement.

[0006] A preferred solution is that there are two groups of driving cylinders, the action ends of the two groups of driving cylinders are hinged to the bottoms of the two groups of second connecting rods respectively, and the mounting ends of the two groups of driving cylinders are hinged to the bottom of the mounting frame.

[0007] A preferred solution is that both groups of the second connecting rods are L-shaped structures, and the L-shaped structure includes a long side and a short side, and the angle between the long side and the short side is greater than 90 degrees. The long side is hinged to the mounting frame and the mounting plate, and the short side is connected to the action end of the driving cylinder.

[0008] A preferred solution is that the blocking structure further comprises a connecting block, the two ends of which are respectively connected to the two groups of short sides.

[0009] A preferred solution is that the first connecting rod and the second connecting rod are arranged in parallel.

[0010] A preferred solution is a feeding conveyor line, comprising a roller conveyor line, wherein the blocking structure is arranged at the end of the roller conveyor line, and the mounting frame is connected to the bottom of the roller conveyor line. BRIEF DESCRIPTION OF THE DRAWINGS
