[0028] Reference Figures 1 to 3 The brick cutting machine of the utility model is made into the following embodiments:
[0029] A brick cutting machine comprises: a base frame 100, a driving mechanism 200, a top knife 300 and a bottom knife 400.
[0030] The top knife 300 and the bottom knife 400 are arranged up and down, and the top knife 300 is arranged above the bottom knife 400. The top knife 300 and the bottom knife 400 are both connected to the base frame 100.
[0031] The driving mechanism 200 is used to drive the top knife 300 downward to approach the bottom knife 400. The driving mechanism 200 includes a driving handle 210, a driving connecting rod 220 and a driving swing rod 230.
[0032] The driving handle 210, the driving connecting rod 220 and the driving swing rod 230 are hinged to each other in sequence and form a quadrilateral connecting rod mechanism with the base frame 100. Specifically, the driving handle 210 has a connection end rotatably hinged to the base frame 100. The driving swing rod 230 has a hinge portion 231 hinged to the base frame 100. The driving connecting rod 220 has a first end and a second end respectively transmission-hinged to the driving handle 210 and the driving swing rod 230. The hinge axes of the driving handle 210, the driving connecting rod 220 and the driving swing rod 230 all extend in the front-to-back direction. The driving swing rod 230 has a driving portion 232 eccentrically arranged with the hinge portion 231. The driving portion 232 is connected to the top knife 300.
[0033] In actual use, the brick is placed between the top knife 300 and the bottom knife 400, and the cutting position is aligned with the top knife 300 and the bottom knife 400. Then the driving handle 210 is rotated relative to the base frame 100, and the driving link 220 drives the driving swing rod 230 to rotate around the hinge 231, so that the top knife 300 is driven downward by the driving part 232 to achieve the cutting of the brick between the top knife 300 and the bottom knife 400. The brick cutting machine of the utility model can conveniently drive the top knife 300 and the bottom knife 400 to approach each other through the driving mechanism 200 of the four-bar structure, so that the brick is cut by the top knife 300 and the bottom knife 400 arranged up and down, and the brick disconnection position is not easy to deviate or skew, thereby reducing the loss of bricks.
[0034] The base frame 100 is in the shape of a square frame. The base frame 100 has a brick cutting opening that passes through from front to back, and the top knife 300 and the bottom knife 400 are respectively arranged at the upper and lower ends of the brick cutting opening. In this embodiment, the base frame 100 includes: a top frame 110, a bottom frame 120 and a side frame 130. The top frame 110 and the bottom frame 120 are arranged up and down, and the top frame 110 is arranged above the bottom frame 120. The side frames 130 are arranged in pairs on the left and right sides between the top frame 110 and the bottom frame 120. The top frame 110 and the bottom frame 120 are respectively fixedly connected to the upper and lower ends of the side frame 130 to form a rectangular brick cutting opening.
[0035] In this embodiment, the top knife 300 and the bottom knife 400 are both in the shape of rectangular plates. In order to make the brick section neat and the breaking position easy to control, the top knife 300 and the bottom knife 400 have a pointed end at one end facing each other. Specifically, in the cross section perpendicular to the left and right directions, the bottom of the top knife 300 and the top of the bottom knife 400 are both in a pointed shape.
[0036] The side plate has a receiving groove 131 extending up and down. The left and right ends of the top knife 300 and the bottom knife 400 are both embedded in the receiving groove 131.
[0037] In order to meet the needs of cutting bricks of different thicknesses, the left and right ends of the bottom knife 400 are respectively adjustably connected to the two side panels along the up and down direction. In this embodiment, the side panels have a plurality of sockets 132 that pass through from front to back. The plurality of sockets 132 are arranged in an array along the up and down direction. The left and right ends of the bottom knife 400 are provided with pin holes corresponding to the sockets 132. The pin holes are detachable and provided with pins. In actual use, by plugging and pulling out the pins, the pin holes can be aligned with the sockets 132 at different heights, thereby achieving the height adjustment of the bottom knife 400, thereby meeting the needs of bricks of different thicknesses.
[0038] The top frame 110 has a limit portion that can be adjusted in the up-down direction, and the limit portion is arranged on the upper side of the top knife 300 to limit the upper limit position of the top knife 300. In this embodiment, the top frame 110 is threaded with an adjusting screw 111. The axial direction of the adjusting screw 111 extends in the up-down direction and is arranged on the upper side of the top knife 300. The limit portion is arranged at the lower end of the adjusting screw 111. A rotating wheel for convenient rotation is fixed at the upper end of the adjusting screw 111.
[0039] In this embodiment, the left and right ends of the top knife 300 are slidably embedded in the accommodating groove 131. The top knife 300 is elastically connected to the base frame 100 along the up-down direction, and the driving swing rod 230 is disposed on the upper side of the top knife 300. The upper end of the top knife 300 abuts against the edge of the driving part 232.
[0040] The left and right ends of the top knife 300 are both provided with a tension spring 310 connected to the base frame 100. The upper end of the tension spring 310 is fixedly connected to the top frame 110, and the lower end of the tension spring 310 is fixedly connected to the top knife 300. The elastic force of the tension spring 310 acts on the base frame 100 and the top knife 300, so that the top knife 300 has a tendency to move upward relative to the base frame 100. When the driving part 232 rotates around the hinge part 231, the top knife 300 can overcome the elastic force of the tension spring 310 and push downward; when the driving part 232 is reset, the top knife 300 is reset upward under the elastic force of the tension spring 310; it is convenient to quickly perform multiple brick cutting operations.
[0041] In a further embodiment, in order to facilitate laying down the bricks to be cut, support blocks 410 are provided on both the front and rear sides of the bed knife 400. In actual use, the support blocks 410 on the front and rear sides of the bed knife 400 can provide support for the bricks so that they can be stably placed on the upper side of the bed knife 400.
[0042] In order to make the bottom surface of the brick contact with the bottom knife 400 when cutting the brick, and not hinder the brick from being stably placed on the brick cutting opening, in this embodiment, the upper end of the support block 410 has a supporting panel 420 elastically arranged up and down. The supporting panel 420 has a flat upper end surface. A plurality of compression springs are evenly arranged between the supporting panel 420 and the support block 410. In actual use, the brick can be stably placed on the two supporting panels 420, and when the top knife 300 is pressed downward, the brick can be pressed downward, so that the brick presses the compression spring and presses against the bottom knife 400.
[0043] The driving handle 210 is in the shape of a long strip. The connecting end is provided at one end of the driving handle 210, and a retractable handle is provided at the other end of the driving handle 210. In this embodiment, the driving handle 210 includes: a handle body 211 and a handle barrel 212. The connecting end is provided at one end of the handle body 211, and the handle barrel 212 is sleeved at the other end of the handle body 211. The handle barrel 212 is in the shape of a cylinder, and a tightening screw is provided along the radial thread.
[0044] In this embodiment, in order to save effort in brick cutting, the distance between the first end of the driving connecting rod 220 and the connecting end is preferably smaller than the distance between the handle and the connecting end. When cutting bricks, the operator controls the driving handle 210 to rotate through the handle, and the torque of the handle is greater, which can drive the driving connecting rod 220 to move more effortlessly through the lever principle.
[0045] Similarly, the driving rocker arm 230 pushes the top knife 300 downward through the edge of the driving part 232. It is preferred that the distance between the edge of the driving part 232 and the hinge part 231 is smaller than the distance between the second end of the driving connecting rod 220 and the hinge part 231, so that the torque can be increased when the driving connecting rod 220 drives the driving rocker arm 230 to flip, thereby saving effort in pushing the top knife 300 downward to achieve the brick cutting operation.
[0046] In a further embodiment, a tug wheel 121 is provided at the left end of the base frame 120. The rotation axis of the tug wheel 121 extends in the front-rear direction. An extended handle 123 is provided at the other end of the base frame 120. The right side of the brick cutter can be lifted by the extended handle 123, so that the brick cutter can be towed by the tug wheel 121 for easy movement.
[0047] The extended handle 123 is preferably foldable. One end of the extended handle 123 is rotatably connected to the base frame 100, and the base frame 100 is removably provided with a limit pin 122. In actual use, the extended handle 123 can be flipped down to be flush with the base frame 120, and the extended handle 123 is pressed against the limit pin 122 to prevent it from flipping up. After the movement of the brick cutter is completed, after the limit pin 122 is removed and pulled out, the extended handle 123 can be flipped up to be flush with the side panel, so that the extended handle 123 can be folded and stored.
