[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment, as Figures 1 to 7 shown, a block making machine provided by the present invention includes a machine body 1, a lifting die box 2 that can move along the height direction of the machine body 1 is arranged on the machine body 1, a vibrator 3 is arranged below the lifting die box 2, an upper die 4 is arranged above the lifting die box 2, a hydraulic cylinder 5 is arranged on the top of the upper die 4, a blanking device 6 is arranged on one side of the machine body 1, and a primary feeding device 7 that is connected to the blanking device 6 and used for feeding the lifting die box 2 is arranged below the blanking device 6. Among them, the machine body 1, the hydraulic cylinder 5, the vibrator 3 and the upper die 4 are existing mature technologies. For example, the vibrator 3 uses a cam as an actuator, and the cam is driven by a motor, a belt and a pulley. This embodiment will not be elaborated here. In order to improve the connection performance between the blanking device 6, the primary feeding device 7 and the lifting die box 2, the present invention makes beneficial improvements to the blanking device 6 and the primary feeding device 7, and adds a secondary feeding device 8.

[0024] Specifically, on one side opposite to the primary feeding device 7, the utility model is provided with a secondary feeding device 8. The secondary feeding device 8 includes a hollow material pushing box 81. On one side of the material pushing box 81, there is a secondary material pushing cylinder 82 that pushes the material pushing box 81 towards the lifting die box 2. The primary feeding device 7 includes a receiving hopper 71 that is movably connected to the feeding device 6. Inside the receiving hopper 71, there is a material turning mechanism 72. On the power input side of the material turning mechanism 72, there is a transmission mechanism 73. The material turning mechanism 72 includes a rotating shaft, and on the rotating shaft, there are material turning plates. The transmission mechanism 73 includes gears that are key-connected to the rotating shafts one by one. The gears are synchronously driven by a chain. The gear located at the beginning of the transmission is provided with a toothed shaft, and the toothed shaft is coaxially connected to the K series reduction motor 622. The power input end of the transmission mechanism 73 is provided with the K series reduction motor 622. On the side of the feeding device 6 facing away from the machine body 1, there is a primary material pushing cylinder 75 connected to the receiving hopper 71. On one side of the machine body 1, there is a frame 10 for installing the feeding device 6 and the primary feeding device 7. On both sides of the frame 10, there are cross beams 11 for supporting the primary feeding device 7. At both ends of the cross beam 11, there are support rods 12. In the middle of the cross beam 11, there is a worm and worm gear assembly 13. The power input end of the worm and worm gear assembly 13 is provided with a handwheel 14.

[0025] In this device, the primary feeding device 7 and the secondary feeding device 8 can perform primary feeding and secondary feeding on the lifting die box 2 successively. Among them, the receiving hopper 71 of the primary feeding device 7 receives sand materials from the feeding hopper 61 under the pushing and pulling of the primary material pushing cylinder 75, continues to move towards the position of the lifting die box 2, and under the stirring action of the material turning mechanism 72 inside it, can ensure the preliminary filling effect of the sand materials; the material pushing box 81 is pushed by the secondary material pushing cylinder 82 towards the lifting die box 2 to level the piled-up part of the sand materials and make the sand materials be filled into the block mold holes in the lifting die box 2 for the second time, further improving the filling effect of the sand materials in the lifting die box 2 and being beneficial to improving the forming quality of the blocks.

[0026] Further, by manually operating the handwheel 14, the worm and worm gear can obtain the driving force. The worm and worm gear change the direction of the handwheel 14 from horizontal to vertical. The cross beam 11 that rotates in cooperation with the worm part converts the rotational motion into a lifting action, thereby enabling the height of the cross beam 11 and the primary feeding device 7 to be finely adjusted, compensating for the connection error between the primary feeding device 7 and the lifting die box 2, and further improving the forming quality of the blocks.

[0027] To improve the practicality of the worm and worm gear assembly 13, the worm and worm gear assembly 13 provided by the utility model includes a transmission box 131 connected to the bottom of the cross beam 11. Inside the transmission box 131, there is a worm gear. On the transmission end of the worm gear, there is a worm that rotates in cooperation with the cross beam 11. Outside the worm, there is an outer sleeve 132. The inner wall of the outer sleeve 132 can be provided with thread teeth that cooperate with the worm, or can be set as a smooth cylinder to play a guiding role.

[0028] To improve the blanking efficiency of the blanking device 6, the blanking device 6 provided by the present utility model includes a blanking hopper 61. The bottom opening of the blanking hopper 61 is an arc-shaped opening. A blanking switch mechanism 62 is arranged on the outer side of the blanking hopper 61. The blanking switch mechanism 62 includes a mounting seat 621 arranged on the side of the blanking hopper 61 facing away from the machine body 1. A K series reduction motor 622 is arranged on the mounting seat 621. A connecting rod assembly 623 is arranged on the power output side of the K series reduction motor 622. An arc-shaped valve plate 624 is arranged at the end of the connecting rod assembly 623. Rotating plates 625 hinged to the blanking hopper 61 are arranged at both ends of the valve plate 624. The K series reduction motor 622 is used to control the connecting rod assembly 623. The connecting rod assembly 623 transmits power to the valve plate 624. The valve plate 624 can swing to open and close the blanking hopper 61 under the hinge action of the rotating plate 625 and the blanking hopper 61. Moreover, the size of the bottom opening of the blanking hopper 61 is designed appropriately, and the immediate reaction effect of opening and closing the bottom opening is good, which can improve the feeding efficiency of this device.

[0029] Furthermore, the connecting rod assembly 623 provided by the present utility model includes a rocker arm 6231 connected to the transmission end of the K series reduction motor 622. A planar moving rod 6232 rotatably connected to the end of the rocker arm 6231 is arranged. A connecting head 6233 rotatably connected to the bottom of the planar moving rod 6232 is arranged. The connecting head 6233 is connected to the valve plate 624. Among them, the K series reduction motor 622 is used to drive the rocker arm 6231 to swing. The rocker arm 6231 drives the planar moving rod 6232 to perform a planar motion, thereby driving the connecting head 6233 and the valve plate 624 to move. The valve plate 624 opens and closes the bottom opening of the blanking hopper 61 under the hinge action of the rotating plate 625.

[0030] To reduce the probability of blanking blockage, two vibrating plates 63 are arranged inside the blanking hopper 61 provided by the present utility model, and the cross sections of the two vibrating plates 63 are in an eight-shaped configuration. Upper ear plates 64 and lower ear plates 65 are arranged at one end of the vibrating plates 63. Both the upper ear plates 64 and the lower ear plates 65 extend out from the vibrating holes opened on the side surface of the blanking hopper 61. Transverse springs 66 are arranged between adjacent upper ear plates and between adjacent lower ear plates. The vibrating holes have a certain margin, ensuring that the vibrating plates 63 have a small vibration amplitude and will not cause a large area of sand leakage. The vibrating plates 63 can generate a small deviation amplitude under the flow action of the sand material. Coupled with the resetting action of the transverse springs 66, the vibrating plates 63 act on the sand material in the opposite direction, avoiding the occurrence of large-area blockage.

[0031] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
