Description

Technical Field

[0001] This utility model relates to the field of sand and gravel screening technology, and in particular to a sand and gravel screening device for mortar production. Background Technology

[0002] Sand and gravel screening devices are widely used in industries such as construction, road construction, and mining to classify sand and gravel particles of different sizes. Currently, common screening devices mainly include two types: closed and open.

[0003] Enclosed screening devices typically have a screen fixed inside the screening machine, equipped with cleaning mechanisms such as rotating brushes, airflow nozzles, or vibratory tapping to remove sand and gravel particles clogging the screen holes. However, due to the limited space between the screen and the machine casing, the movement range of the cleaning mechanism is restricted, making it difficult to effectively clean every area of ​​the screen. Especially when the particle size of the sand and gravel is close to the screen hole size, material jamming is very likely to occur, resulting in the cleaning mechanism being unable to completely remove residues. After long-term operation, the screening efficiency decreases significantly.

[0004] To address the issue of incomplete screen cleaning, some equipment employs an open structure, where the top cover or side walls of the screening machine are designed to open, allowing operators to directly remove the screen for manual cleaning or replacement. While this open design improves the ease of screen maintenance, in actual production, the vibration or rotation of sand and gravel particles generates a significant amount of dust. Even with a dust collection device, the insufficient sealing of the open structure allows dust to escape from the openings into the working environment, causing air pollution and harming the health of operators.

[0005] Therefore, there is an urgent need in the existing technology for a sand and gravel screening device that can both easily remove the screen for thorough cleaning or replacement and effectively seal the screening device to prevent dust from escaping. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 This utility model is a sand and gravel screening device for mortar production, including a shell 1. A vibrating motor 2 is provided on the upper surface of the shell 1. A screen is detachably provided inside the shell 1. A slag outlet 3 is provided on one side of the shell 1 corresponding to the side of the screen. A baffle 4 controlled by a servo motor 15 is provided at the slag outlet 3. The baffle 4 is hinged to the upper end of the slag outlet 3. A discharge port 5 is provided on the other side of the shell 1. A feed inlet 6 is provided on the upper surface of the shell 1.

[0025] In this embodiment, the rudder blade 1501 of the servo motor 15 is rotatably connected to the side of the baffle 4. When the servo motor 15 drives the rudder blade 1501 to rotate, the rudder blade 1501 drives the baffle 4 to open and close.

[0026] Furthermore, the screen includes a first screen 7 and a second screen 8. The first screen 7 is located near the feed inlet 6, and the second screen 8 is located below the first screen 7. The inner wall of the outer shell 1 is provided with a slot 9 for engaging the first screen 7 and the second screen 8.

[0027] Furthermore, the outer casing 1 is provided with a protrusion 10 for placing the first screen 7 and the second screen 8 near the slag outlet 3. The protrusion 10 is "L-shaped". One side of the first screen 7 and the second screen 8 is engaged in the slot 9, and the other side of the second screen 8 is limited by the protrusion 10. The setting height of the protrusion 10 is lower than the setting height of the slot 9.

[0028] In this embodiment, when the first screen 7 and the second screen 8 need to be placed inside the outer casing 1, one end of the first screen 7 and the second screen 8 is first inserted from the slag outlet 3 and engaged in the slot 9. Then, the other end of the first screen 7 and the second screen 8 is placed at the notch of the protrusion 10, and the protrusion 10 limits the first screen 7 and the second screen 8.

[0029] Furthermore, the mesh diameter of the first screen 7 is larger than that of the second screen 8. During the screening of sand and gravel, the larger diameter sand and gravel will remain on the first screen 7 and the second screen 8 respectively.

[0030] Furthermore, a hopper 11 is provided below the second screen 8, and the sides of the hopper 11 are all inclined, with one side of the hopper 11 connected to the discharge port 5.

[0031] In this embodiment, the inclined side of the hopper 11 allows the fine sand and gravel that have passed through the sieve to fall into the hopper 11 and slide down to the bottom of the hopper 11 and be discharged from the outlet 5 under the action of vibration.

[0032] Furthermore, a shock-absorbing mechanism 12 is provided at the four corners of the lower surface of the outer shell 1. The shock-absorbing mechanism 12 includes a base plate 1201 and a shock-absorbing spring 1202. One end of the shock-absorbing spring 1202 is fixedly connected to the base plate 1201, and the other end of the shock-absorbing spring 1202 is connected to the lower surface of the outer shell 1 through a support member 1203.

[0033] In this embodiment, the shock absorption mechanism 12 reduces the ground impact force generated by the vibration motor 2 on the housing 1, and more effectively increases the service life of the device.

[0034] Furthermore, a plurality of water nozzles 13 are embedded on the upper surface of the outer shell 1, and the water nozzles 13 are connected to an external water pipe and a water pump.

[0035] In this embodiment, the water nozzle 13 is provided so that water can be sprayed into the housing 1 when connected to an external water pipe and water pump, reducing dust generated during sieving and cleaning the sand and gravel.

[0036] Furthermore, a control mechanism 14 is provided on the upper surface of the outer casing 1. The control mechanism 14 is electrically connected to the vibration motor 2 and the servo motor 15. The vibration motor 2 and the servo motor 15 are controlled by the control mechanism 14.

[0037] The working principle of the sand and gravel screening device for mortar production provided by this utility model is as follows:

[0038] When in use, start the vibration motor 2 and pour the sand and gravel to be screened into the outer shell 1 through the feed port 6. Control the opening and closing angle of the baffle 4 by controlling the servo motor 15 to control the discharge speed of the slag outlet 3. The first screen 7 and the second screen 8 retain the larger particles in the sand and gravel and discharge them through the slag outlet 3. The smaller sand particles fall into the hopper 11 and are discharged from the discharge port 5, thus realizing the screening of sand and gravel. If it is necessary to reduce the dust generated during screening, the external water pipe and water pump can be connected to spray water into the outer shell 1, and the sand and gravel can be cleaned at the same time.

[0039] This utility model provides a sand and gravel screening device for mortar production. The device has a first screen 7 and a second screen 8 inclinedly arranged inside the outer shell 1. When the vibrating motor 2 performs sand and gravel screening, the stones larger than the mesh size can move from the inclined first screen 7 and second screen 8 to the slag outlet 3 under the action of vibration. By setting a baffle 4 controlled by a servo motor 15, the discharge speed of the stones can be controlled by controlling the opening and closing angle of the baffle 4. At the same time, the setting of the baffle 4 also makes it convenient for the user to remove the screen for cleaning or replacement, and further prevents the dust generated during screening from escaping.
