[0017] The following is a clear and complete description of the technical solutions in the embodiments of the utility model patent in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model patent, not all of them. Based on the embodiments in the utility model patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model patent.

[0018] like Figure 1 and 2A baffle mechanical automatic switch device shown in the figure includes a material trough 1, a guide groove 2 and a baffle 3. Two groups of discharge ports are arranged below the material trough 1, namely a first discharge port 4 and a second discharge port 5. The bottom of the guide groove 2 is rotatably connected to the inside of the trough 1 near the first discharge port 4, and the top of the baffle 3 is rotatably connected to the inside of the trough 1 near the second discharge port 5. The guide groove 2 and the bottom of the baffle 3 are hinged by a connecting rod 6. A pushing device 7 is also connected to the side of the guide groove 2 away from the baffle 3, and a material distribution channel is between the guide groove 2 and the baffle 3.

[0019] The fixed end of the pushing device 7 is movably hinged with a connecting seat 8, and the connecting seat 8 is installed outside the material trough 1. The output end of the pushing device 7 passes through one side of the material trough 1 and is movably hinged with the outer side of the guide groove 2.

[0020] The pushing device 7 is a cylinder or an electric push rod, which can push one side of the guide groove 2 to achieve overall drive. Since the cylinder or electric push rod does not contact the material, the overall working service life is improved, the laying of pipelines and electricity is reduced, which is convenient for production and manufacturing, and later maintenance and inspection are quite convenient.

[0021] There are two groups of connecting rods 6, one end of the two groups of connecting rods 6 is movably hinged with the guide groove 2 and the baffle 3 respectively, the two groups of connecting rods 6 are movably connected, the connection between the two groups of connecting rods 6 is at the inner side of the bend, and two groups of blocks 9 are symmetrically arranged, each group of blocks 9 is relatively obliquely arranged on the connecting rod 6, and the two groups of baffles 9 limit the minimum bending angle of the two groups of connecting rods 6. At the minimum bending angle, the connection can drive the baffle 3 to move.

[0022] A counterweight 10 is arranged on the top of the baffle 3 outside the material trough 1. The counterweight 10 and the baffle 3 are arranged at an angle. The center of gravity of the counterweight 10 is always located on one side of the baffle 3, and the counterweight 10 and the baffle 3 form a lever effect.

[0023] When the pushing device 7 is at the minimum stroke, the bottom of the baffle 3 is fitted and arranged on one side of the trough 1 between the first discharge port 4 and the second discharge port 5, and a limit block 11 is fixedly installed on the inner side of the trough 1 close to the guide groove 2. The limit block 11 is fitted and limited with the inner side of the baffle 3, and a first limit plate 12 is arranged at the bottom of the baffle 3. The L-shaped limit plate is fitted and limited with the trough 1 between the first discharge port 4 and the second discharge port 5, so as to realize the discharge of material from the second discharge port 5 to the first discharge port 4.

[0024] When the pushing device 7 is at the minimum stroke, the bottom of the guide groove 2 is fitted on the other side of the trough 1 between the first discharge port 4 and the second discharge port 5. The guide groove 2 is arranged in an arc shape, and a second limit plate 13 is arranged at the bottom of the guide groove 2. The L-shaped limit plate fits and limits the trough 1 between the first discharge port 4 and the second discharge port 5, thereby realizing the transformation of material discharge from the first discharge port 4 to the second discharge port 5.

[0025] The working principle of the utility model is:

[0026] Opening of the baffle 3: The guide groove 2 and the baffle 3 are connected by a connecting rod 6, such as Figure 1 A stopper 9 is welded at the joint of the connecting rod 6. When the guide groove 2 is driven to move to the left by the pushing device 7, the stopper 9 at the joint of the connecting rod 6 approaches, which pushes the baffle 3 forward together, and the stopper 9 of the trough 1 is opened accordingly. Under the maximum stroke of the pushing device 7, the material is discharged from the first discharge port 4 to the second discharge port 5.

[0027] Closing of baffle 3: Figure 2 As shown, when the guide groove 2 moves to the right under the action of the cylinder, when the connecting rod 6 is loosened, the baffle 3 will slowly close under its own weight, and a counterweight block 10 of equal weight is added to the other side of the rotation connection of the baffle 3, so that the baffle 3 can be automatically closed under the principle of leverage, and at the same time, a limit block 11 is added to the inner side of the trough 1, so that the baffle 3 does not affect the guidance of the guide groove 2 to the material when it is completely closed, and the material can be discharged from the second discharge port 5 to the first discharge port 4 under the minimum stroke of the pushing device 7.

[0028] The baffle in the utility model is connected to the guide groove by a connecting rod. After adding a counterweight on the outside, the opening and closing functions of the trough baffle are fully satisfied. At the same time, the synchronization with the guide groove is guaranteed. It will close synchronously with the opening of the guide groove and close first, without affecting the guidance of the guide groove for the material. The purely mechanical coordination design reduces the laying of pipelines and electricity, facilitates production, and is very convenient for later maintenance and inspection.

It should be understood that the above are only specific implementation methods of the utility model patent and are not used to limit the protection scope of the utility model patent. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model patent should be included in the protection scope of the utility model patent.
