[0033] A brick cutting device comprises a base 1, a gantry 2 is mounted on one side of the base 1 via rivets 3, a cutting device is mounted on the gantry 2, and a feeding device is provided between the base 1 and the cutting device;

[0034] The cutting device includes a transmission shaft 6, an upper blade connecting rod 8 and a cam 1 7 are installed at one end of the transmission shaft 6, a lower blade connecting rod 17 and a cam 2 19 are installed at the other end of the transmission shaft 6, a handle connecting rod 9 is installed at one end of the cam 1 7, an upper blade 5 is installed at the lower end of the upper blade connecting rod 8, and a lower blade 18 is installed at the lower end of the lower blade connecting rod 17;

[0035] The feeding device includes a groove wheel mechanism, which includes a dial 14 rotatably connected to the base 1, a groove wheel 13 engaged with the outer side of the dial 14, a belt 15 for transmission is installed between the dial 14 and the transmission shaft 6, and a transmission wheel compatible with the belt 15 is provided on the dial 14 and the transmission shaft 6. A feeding roller 16 rotatably connected to the base 1 is installed at one end of the groove wheel 13.

[0036] In this example, a through hole is opened at the upper end of the gantry 2 to fit the rivet 3 with clearance, two cylinders for support and fixation are welded between the two plates of the gantry 2, and a handle 10 is installed on the handle connecting rod 9.

[0037] In this example, a measuring ruler 11 is installed at the top edge of the base 1 , and two matching holes are opened inside the base 1 for clearance matching with the feed roller 16 and the dial 14 respectively.

[0038] Among them, several neatly arranged arc-shaped protrusions on the top of the base 1 reduce the friction area between the bricks and the base 1, making feeding more convenient. The base 1 is riveted to the gantry 2, so that the base 1 can be folded around the axis of the rivet 3, which is also more suitable for work environments with uneven potholes.

[0039] In this example, corresponding sliding grooves cooperating with the upper blade 5 and the lower blade 18 are respectively opened on the front and rear plates of the gantry 2, and cylinders located on the front and rear plates are provided on the inner side of the lower end of the gantry 2. A roller 4 is movably installed in the gantry 2 through two cylinders.

[0040] Among them, the roller 4 is designed for feeding. Bricks are placed on the outer surface of the roller 4 to push the material to rotate the roller 4. The roller and the gantry 2 have rolling friction, and the required thrust is smaller, which improves the work efficiency.

[0041] In this embodiment, the feeding roller 16 is knurled and hollow inside. One end of the feeding roller 16 is fixed to the groove wheel 13. The groove wheel 13 has four through grooves around its axis.

[0042] In this example, a rectangular through groove for mounting a feed roller 16 is provided on the base 1 , the base 1 has several arc-shaped protrusions, and a support frame 12 is mounted on the bottom of the base 1 .

[0043] In this example, cam 1 7 is movably connected to the upper blade connecting rod 8 , and cam 2 19 is movably connected to the lower blade connecting rod 17 .

[0044] To sum up, the user places the bricks to be cut on the protrusions of the feed roller 1 and the base 1, and adjusts the cutting angle. After placing the bricks, the user holds the handle 10 and applies force to rotate it counterclockwise. At this time, cam 1 7 rotates and drives the transmission shaft 6 to rotate. Cam 2 19 at the other end of the rotating shaft 6 also rotates. Then, under the action of the two cams, the lower blade 18 is driven upward by the lower blade connecting rod 17, and the upper blade 5 is driven downward by the lower blade connecting rod 17. In addition, during the rotation of the transmission shaft 6, the belt 15 is used to drive the dial 14 to rotate, and the dial 14 drives the groove wheel 13 to move intermittently. The groove wheel 13 drives the feed roller 16 to move the brick above it a fixed distance. The user continuously rotates the handle 10 to continuously process bricks of equal width.

[0045] A brick cutting device is provided, which can adjust the position of the cut bricks during cutting so that the sizes of the cut bricks are kept as uniform as possible.

[0046] Beneficial effects:

[0047] 1. The brick cutting device has a simple structure through an overall mechanized structure and can adjust the position of bricks while cutting, so that the size of the cut bricks can be kept as uniform as possible.

[0048] 2. The brick cutting device, through the transmission principle of the mechanical structure, the brick cutting machine can reduce the physical exertion of workers when cutting bricks, thereby reducing the labor intensity of workers and improving work efficiency.
