Description

Technical Field

[0001] This utility model relates to the field of sand making technology, specifically to a material feeding mechanism for sand making equipment. Background Technology

[0002] In the sand production process, the material feeding stage must ensure the accuracy of raw material processing, the flexibility of position matching, and the stability of material feeding in order to connect with subsequent production.

[0003] Chinese utility model patent CN219408470U discloses a wet dust suppression and feeding device for manufactured sand, which includes "machine cover 1, machine head roller 2, baffle 3, material distribution net 4, water spray network 5, steel wire rope 6, adjusting spring 7, conveyor belt 8, rotating shaft 9, and spray nozzle 10". The material discharge side of the machine head roller 2 is provided with baffle 3 and material distribution net 4. The material distribution net 4 is in a horizontal state. The side of the material distribution net 4 near the machine head roller 2 is fixed to the rotating shaft 9. The two ends of the rotating shaft 9 are rotatably connected to the machine cover 1. A steel wire rope 6 is provided on the side of the material distribution net 4 away from the head roller 2. The steel wire rope 6 passes through the top of the cover 1 and is equipped with an adjusting spring 7. The baffle 3 is located above the material distribution net 4 and is tilted towards the material distribution net 4. The water spraying pipe network 5 is located directly below the material distribution net 4 and is equipped with several spray nozzles 10”. However, the existing technology has a drop from the discharge port to the hopper, which will generate dust during operation. The dust will pollute the working environment, and the existing technology cannot flexibly adjust the position according to different discharge points. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding mechanism for sand making equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material feeding mechanism for sand making equipment, comprising a support frame, a plurality of casters mounted on the bottom of the support frame, a hopper sleeved on the top of the support frame, a plurality of filter screens sleeved on the inner wall of the hopper, a first discharge pipe fixedly connected to the bottom of the hopper, a valve body mounted on the first discharge pipe, a collar sleeved on the outer surface of the first discharge pipe, a pawl rotatably mounted on the bottom of the collar, a limit block fixedly connected to the bottom of the collar, a spring fixedly connected to one side of the limit block, one end of the spring fixedly connected to one side of the pawl, a second discharge pipe rotatably connected to the bottom of the first discharge pipe, and a ratchet sleeved on the top of the second discharge pipe.

[0006] The beneficial effects of this utility model are as follows: the universal wheels with brakes facilitate the movement and fixation of the device to the target position, preventing displacement during operation. The multi-layer gradient filter screen installed inside the hopper can classify and filter the raw materials, improving their purity. The ratchet and pawl, in conjunction with a spring, enable rapid adjustment of the discharge direction of the second discharge pipe. A reserved interface for a vibration motor is provided, which effectively prevents material from clogging the filter screen and discharge pipe after the vibration motor is installed, improving the operational efficiency of sand making production.

[0007] To achieve convenient movement and stable fixation of the device:

[0008] The omnidirectional wheel is further configured to have a braking device.

[0009] By adopting the above technical solution, the universal wheels with brakes can easily move the device to the target position. After the brakes are locked, displacement during operation can be avoided, ensuring the stability of the material feeding process.

[0010] To achieve the purification of raw materials:

[0011] The filter screens are further configured such that the pore size decreases sequentially from top to bottom.

[0012] By adopting the above technical solution, filter screens with decreasing pore size can screen materials step by step, thereby improving the purity of raw materials.

[0013] To prevent raw material blockage and ensure smooth material feeding:

[0014] The further configuration includes: bolt holes on the outer surface of the hopper and the outer surface of the collar that match the feet of the vibrating motor.

[0015] By adopting the above technical solution, the pre-set bolt holes provide a convenient installation interface for external vibration motors, and vibration motors can be flexibly added according to the characteristics of materials, effectively preventing material blockage in the hopper and discharge pipe.

[0016] To achieve flexible adjustment of the discharge angle:

[0017] The ratchet is further configured such that the pawl and ratchet engage and disengage periodically.

[0018] By adopting the above technical solution, the pawl and ratchet engage and disengage periodically, allowing the second discharge pipe to achieve unidirectional rotation adjustment at any angle, and automatically engage under the action of the spring to prevent angle deviation caused by vibration during operation.

[0019] To achieve overall structural stability:

[0020] The configuration is further defined as follows: the top of the support frame is coplanar with the top of the hopper, the support frame is fixedly connected to the hopper, the top of the second discharge pipe is coplanar with the top of the ratchet, and the second discharge pipe is fixedly connected to the ratchet.

[0021] By adopting the above technical solution, the structural stability between the support frame and the hopper, as well as between the second discharge pipe and the ratchet, is ensured.

[0022] To ensure a secure connection between the filter and the feeding components:

[0023] The hopper is further configured to be fixedly connected to several filter screens, and the first discharge pipe is fixedly connected to a collar.

[0024] By adopting the above technical solution, the fixed connection between the filter screen and the hopper, as well as the fixed connection between the collar and the first discharge pipe, effectively avoids the loosening or misalignment of components caused by vibration.

[0025] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0033] Please see Figures 1 to 5A material feeding mechanism for sand making equipment includes a support frame 1, a plurality of casters 2 installed at the bottom of the support frame 1, a hopper 3 sleeved on the top of the support frame 1, a plurality of filter screens 4 sleeved on the inner wall of the hopper 3, a first discharge pipe 5 fixedly connected to the bottom of the hopper 3, a valve body 6 installed on the first discharge pipe 5, a collar 7 sleeved on the outer surface of the first discharge pipe 5, a pawl 8 rotating at the bottom of the collar 7, a limit block 9 fixedly connected to the bottom of the collar 7, a spring 10 fixedly connected to one side of the limit block 9, one end of the spring 10 fixedly connected to one side of the pawl 8, a second discharge pipe 11 rotatably connected to the bottom of the first discharge pipe 5, and a ratchet 12 sleeved on the top of the second discharge pipe 11.

[0034] In this embodiment, as Figure 1 As shown, the bottom of the support frame 1 is equipped with several casters 2, the top of the support frame 1 is fitted with a hopper 3, and the inner wall of the hopper 3 is fitted with several filter screens 4. The top of the support frame 1 and the top of the hopper 3 are coplanar, and the support frame 1 and the hopper 3 are fixedly connected.

[0035] In this embodiment, as Figure 2 As shown, several filter screens 4 are fitted on the inner wall of the hopper 3. A first discharge pipe 5 is fixedly connected to the bottom of the hopper 3. A valve body 6 is installed on the first discharge pipe 5. A collar 7 is fitted on the outer surface of the first discharge pipe 5. Bolt holes matching the vibrating motor base are provided on the outer surface of the hopper 3 and the outer surface of the collar 7. The top of the support frame 1 is coplanar with the top of the hopper 3. The support frame 1 is fixedly connected to the hopper 3. The first discharge pipe 5 is fixedly connected to the collar 7.

[0036] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, a spring 10 is fixedly connected to one side of the limiting block 9, and one end of the spring 10 is fixedly connected to one side of the pawl 8. A ratchet 12 is sleeved on the top of the second discharge pipe 11. The aperture of several filter screens 4 decreases sequentially from top to bottom. The pawl 8 and the ratchet 12 engage and disengage periodically. The top of the second discharge pipe 11 is coplanar with the top of the ratchet 12. The second discharge pipe 11 is fixedly connected to the ratchet 12.

[0037] The working process of the feeding mechanism for this sand making equipment is as follows:

[0038] First, move the device to a suitable position using the casters 2, and then release the brakes on the casters 2 to prevent the device from moving during operation. Next, rotate the second discharge pipe 11 to a suitable position. The rotation of the second discharge pipe 11 drives the ratchet 12 to rotate. As the ratchet 12 rotates, the pawl 8 engages and disengages with the ratchet 12 periodically. When the pawl 8 disengages from the ratchet 12, the pawl 8 compresses the spring 10, putting the spring 10 in a contracted state. When the pawl 8 is not in a disengaged or engaged state with the ratchet 12, the spring 10 releases its elasticity, causing the pawl 8 to move towards the ratchet 12. At this time, the pawl 8... The material falls into the tooth groove of the ratchet 12, that is, the pawl 8 engages with the ratchet 12 to prevent the second discharge pipe 11 from rotating during operation. Then, as needed, the vibrating motor is installed on the bolt holes on the outer surface of the hopper 3 and the outer surface of the collar 7. Then, the raw material is put into the inside of the hopper 3. After several pieces of raw material are filtered by the filter screen 4, they enter the first discharge pipe 5 and finally fall to the top of the valve body 6 (model: electric gate valve). When it is necessary to discharge the material, the valve body 6 is opened, and the raw material enters the second discharge pipe 11 through the bottom end of the valve body 6 and the first discharge pipe 5. The raw material enters the next production stage through one end of the second discharge pipe 11.
