[0016] like Figure 1 and Figure 2As shown in the figure, this embodiment provides a double - outlet and double - door hopper device, including a hopper 1 and a door - opening mechanism. The lower part of the hopper 1 is provided with two downward - extending hopper - shaped channels 101. Each hopper - shaped channel 101 is provided with an outlet at its lower end. The door - opening mechanism includes a first door - opening mechanism and a second door - opening mechanism respectively cooperating with the two outlets. The first door - opening mechanism includes a first material door 205 provided at one of the outlets and a first driving mechanism provided on the hopper 1 to drive the opening and closing of the first material door 205. The second door - opening mechanism includes a second material door 304 provided at the other outlet and a second driving mechanism provided on the hopper 1 to drive the opening and closing of the second material door 304. The double - outlet and double - door hopper device of this embodiment has a fast feeding speed and uniform cloth distribution.

[0017] In this embodiment, the first material door 205 and the second material door 304 are respectively rotatably installed at the lower ends of the two hopper - shaped channels 101, and the rotation axes of the first material door 205 and the second material door 304 are parallel. The first driving mechanism and the second driving mechanism are installed on the same side wall of the hopper 1. When the double - outlet and double - door hopper device of this embodiment is cooperated with a block forming machine, the first door - opening mechanism and the second door - opening mechanism are arranged on the side of the hopper 1 far from the block forming machine, avoiding movement interference between the first door - opening mechanism, the second door - opening mechanism and the block forming machine.

[0018] In this embodiment, the first driving mechanism includes a first driving motor 201 installed on the hopper 1, a driving shaft 202 drivingly connected to the output end of the first driving motor 201, and a connecting rod connected to the driving shaft 202. The connecting rod includes a first crank 203 fixedly connected to the driving shaft 202 and a long rod 204 hinged to the first crank 203. One end of the long rod 204 is hinged to the first material door 205. Preferably, the driving shaft 202 is rotatably installed on the hopper 1, and a set of connecting rods are respectively connected to both ends of the driving shaft 202. The long rods 204 of the two sets of connecting rods are respectively hinged to both ends of the first material door 205. Figure 2 It can be seen that the first material door 205 of this embodiment is far from the first driving mechanism. The long rod 204 of the connecting rod extends to the side of the first material door 205 and is drivingly connected to it. The long rod 204 is misaligned with the second door - opening mechanism, and the driving shaft 202 is rotatably installed on the hopper 1 above the second door - opening mechanism. In this way, the first material door 205 can be opened and closed while ensuring that the hopper 1 does not interfere with the movement of the block forming machine.

[0019] In this embodiment, the second driving mechanism includes a second driving motor 301 installed on the hopper 1, a second crank 302 drivingly connected to the output end of the second driving motor 301, and a short rod 303 hinged to the second crank 302. The other end of the short rod 303 is hinged to the middle of the second feed door 304. The second driving mechanism is arranged below the first driving mechanism, and the second feed door 304 can be controlled by the second crank and the short rod 303.

A handle 105 is installed on the closing door 103. Figure 1 It can be seen that the maintenance window 102, the first driving mechanism, and the second driving mechanism in this embodiment are all arranged on the same side wall of the hopper 1, and the user can conveniently open the maintenance window 102 to clean and maintain the hopper 1.

[0021] Two mounting plates 106 are provided at the upper part of the hopper 1 in this embodiment. When the double - outlet double - opening door hopper device in this embodiment is operating, the hopper 1 is installed on the aggregate truck through the mounting plates 106, and the first driving mechanism and the second driving mechanism are arranged away from the block molding machine. When feeding the material, the first feed door 205 and the second feed door 304 are opened by the first driving mechanism and the second driving mechanism, and the raw materials in the hopper 1 fall into the feeding vehicle through the first feed door 205 and the second feed door 304. The raw materials falling from the two outlets are not likely to accumulate in one place, improving the feeding uniformity. At the same time, the two outlets also accelerate the feeding speed, making the feeding of the aggregate both uniform and fast.
