Description
Technical Field
[0001] The utility model relates to the technical field of melon seed chip processing equipment, and more specifically, it relates to a feeding device for a pair-roller sand making machine for melon seed chip processing. Background Art
[0002] Melon seed chips: The common name of "blue stones" in construction. Blue stones are broken by crushers. The scientific name is blue stones. Melon seed chips are processed crushed stone chips with a particle size of 5-10 mm, commonly known as melon seed chips, which are widely used in the basic decoration projects. With the rapid development of the construction industry, the demand for sand and gravel aggregates has increased sharply. Natural sand resources are limited and mining is restricted. And the machine-made sand processed from melon seed chips, as a substitute for natural sand, is used to meet the growing market demand. In the process of melon seed chip sand making, a pair-roller sand making machine for melon seed chips is needed, also known as a double-roller crusher or a pair-roller sand making machine. The melon seed chips are sent between two relatively rotating rollers of the roller sand making machine through a conveyor belt, and are crushed into fine particles by the extrusion and shearing action of the rollers. And by adjusting the gap between the rollers, the particle size of the discharged material can be accurately controlled to meet the requirements of different building materials.
[0003] However, when the melon seed chips are sent between two relatively rotating rollers of the pair-roller sand making machine through the conveyor belt, the melon seed chips cannot be screened, and it is necessary to avoid oversized melon seed chips entering the pair-roller sand making machine, which may cause damage to the pair-roller sand making machine or affect the quality of the finished product. Summary of the Utility Model
[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a feeding device for a pair-roller sand making machine for melon seed chip processing.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A feeding device for a pair-roller sand making machine for melon seed chip processing, comprising a frame and a conveyor belt. A screening box cooperating with the conveyor belt, a receiving box placed on the frame, and a cylinder installed in the screening box are provided on the frame. The screening box is installed on the frame and corresponds to the feeding port on the pair-roller sand making machine, and the screening box includes a feeding port corresponding to the conveyor belt and a discharging port corresponding to the receiving box.
[0007] A sieve plate for screening melon seed chips and a receiving plate cooperating with the sieve plate are movably connected in the screening box. Leakage holes for small-volume melon seed chips to pass through are formed in the receiving plate, and the receiving plate is placed below the discharging port. A knocking hammer for knocking the sieve plate is installed at the output end of the cylinder.
[0008] Further configured, characterized in that a support plate corresponding to one end of the sieve plate is installed on the inner wall of the screening box, an elastic block is installed on the support plate, and the two support plates are respectively connected to one end of the sieve plate and one end of the material receiving plate through the corresponding elastic blocks. The other end of the sieve plate is movably connected to one side inner wall of the screening box, and the other end of the material receiving plate is movably connected to the other side inner wall of the screening box and corresponds to the discharge port.
[0009] Further configured, characterized in that a guide plate is installed at the bottom of the screening box, and the guide plate is inclined towards the feed inlet of the double-roll crusher.
[0010] By adopting the above technical solutions, the beneficial effects of the present utility model are as follows: When the melon seed slices are sent between the two relatively rotating rollers of the double-roll crusher through the conveyor belt, the melon seed slices can be screened, avoiding large melon seed slices from entering the double-roll crusher and causing damage to the double-roll crusher or affecting the quality of the finished product. Description of the Drawings

Detailed Embodiments
[0014] Refer to Figures 1 to 2 for further description of the embodiments of the present utility model.
[0015] A feeding device for a double-roll crusher 01 for processing melon seed slices, including a frame 1 and a conveyor belt 2. A screening box 3 cooperating with the conveyor belt 2, a material receiving box 4 placed on the frame 1, and a cylinder 5 installed in the screening box 3 are provided on the frame 1. The screening box 3 is installed on the frame 1 and corresponds to the feed inlet of the double-roll crusher 01, and the screening box 3 includes a feed inlet 301 corresponding to the conveyor belt 2 and a discharge port 302 corresponding to the material receiving box 4. A sieve plate 6 for screening melon seed slices and a material receiving plate 7 cooperating with the sieve plate 6 are movably connected in the screening box 3. Leakage holes 701 facilitating the passage of small-volume melon seed slices are formed in the material receiving plate 7, and the material receiving plate 7 is placed below the discharge port 302. A knocking hammer 8 for knocking the sieve plate 6 is installed at the output end of the cylinder 5.
[0016] Working principle: The melon seeds are transported by the conveyor belt 2 and enter the screening box 3 through the feeding port 301 and fall on the sieve plate 6 for screening. The melon seeds of appropriate size fall through the sieve holes of the sieve plate 6 between two relatively rotating rollers in the pair-roller sand making machine 01 for processing. The cylinder 5 works to drive the knocking hammer 8 to knock on the sieve plate 6 to make the sieve plate 6 vibrate, facilitating the melon seeds of appropriate size on the sieve plate 6 to better fall into the pair-roller sand making machine 01 for processing and improving the screening efficiency. At the same time, the oversized melon seeds that cannot pass through the sieve holes on the sieve plate 6 and the melon seeds that have not had time to pass through the sieve holes on the sieve plate 6 gradually shift and fall on the receiving plate 7 during the vibration of the sieve plate 6. When the knocking hammer 8 knocks on the sieve plate 6 and the sieve plate 6 moves downward to knock on the receiving plate 7, the receiving plate 7 vibrates, so that the melon seeds that have not had time to pass through the sieve holes on the sieve plate 6 fall into the pair-roller sand making machine 01 through the leakage holes 701 on the receiving plate 7 for processing. The oversized melon seeds that cannot pass through the leakage holes 701 shift during the vibration on the receiving plate 7 and are gradually discharged from the discharge port 302 and fall into the receiving box 4 for collection. Furthermore, it is avoided that the oversized melon seeds directly fall into the pair-roller sand making machine and the oversized melon seeds are screened out for subsequent further processing and use. When the melon seeds are sent between the two relatively rotating rollers of the pair-roller sand making machine through the conveyor belt 2, the melon seeds can be screened, and it is avoided that the oversized melon seeds enter the pair-roller sand making machine, which may damage the pair-roller sand making machine or affect the quality of the finished product.
[0017] Two support plates 9 corresponding to one end of the sieve plate 6 and one end of the receiving plate 7 are installed on the inner wall of the screening box 3. Elastic blocks 10 are installed on the support plates 9. The two support plates 9 are respectively connected to one end of the sieve plate 6 and one end of the receiving plate 7 through the corresponding elastic blocks 10. The other end of the sieve plate 6 is movably connected to one side inner wall of the screening box 3. The other end of the receiving plate 7 is movably connected to the other side inner wall of the screening box 3 and corresponds to the discharge port 302.
[0018] When the cylinder 5 drives the knocking hammer 8 to knock on the sieve plate 6, the elastic blocks 10 on the support plate 9 corresponding to the sieve plate 6 are deformed. With the sieve plate 6 being movably connected to the screening box 3, the sieve plate 6 can smoothly vibrate and produce a small-angle inclination change, enabling the melon seeds on the sieve plate 6 to vibrate and gradually shift during the vibration, facilitating the melon seeds on the sieve plate 6 to fall on the receiving plate 7. At the same time, when the sieve plate 6 is knocked, it moves downward to knock on the receiving plate 7, enabling the receiving plate 7 to vibrate and produce a small-angle inclination change, realizing the vibration of the melon seeds on the receiving plate 7 and their gradual displacement during the vibration, so as to achieve the discharge of the oversized melon seeds on the receiving plate 7 from the discharge port 302.
[0019] Cooperating with the sieve plate 6 and the receiving plate 7 being movably connected to the screening box 3, when the knocking hammer 8 knocks on the sieve plate 6, the sieve plate 6 and the receiving plate 7 can vibrate, and making the sieve plate 6 and the receiving plate 7 produce a small angle of inclination is beneficial to the displacement of the melon seeds on the sieve plate 6 and the receiving plate 7.
[0020] A guide plate 11 is installed at the bottom of the screening box 3. The guide plate 11 is inclined towards the feeding port of the double-roll crusher 01, facilitating the smooth fall of the melon seeds through the sieve holes on the sieve plate 6 and the leakage holes 701 on the material receiving plate 7 into the double-roll crusher 01, and preventing the waste caused by the melon seeds falling outside the double-roll crusher 01.
[0021] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
