Description

Technical Field

[0001] The present application belongs to the technical field of discharging equipment, and specifically relates to a material blocking device. Background Art

[0002] The silo feeder is used to intermittently open and close the discharge port to control the amount of material discharged to the belt or other equipment that transmits or uses materials, which is convenient for the use of materials. Due to the differences in the characteristics of different materials, some materials tend to accumulate at the discharge port after the feeder closes the discharge port. When the discharge port is opened again, the material will not flow out of the discharge port, that is, the discharge port is blocked, which will cause the subsequent devices to be unable to obtain materials in time, reducing production efficiency.

[0026] In order to enable those skilled in the art to understand the present application more clearly, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of this application.

[0028] See also Figures 1-6 In a first embodiment of the present application, a material blocking device is provided, comprising a bracket 1, a first baffle 2, a second baffle 3, and a drive mechanism 5. The material blocking device is provided at a discharge port of a silo feeder, and is used to solve the problem of accumulation and blockage of material 10 at the discharge port to a certain extent.

[0029] The bracket 1 is a structural member, which can be used to support at least the first baffle 2 and the second baffle 3. A discharge port is provided in the middle of the bracket 1, and the discharge port corresponds to the discharge port of the silo feeder.

[0030] The first baffle 2 is slidably mounted on the bracket 1 and operable to shield the discharge port. The second baffle 3 is detachably mounted on the first baffle 2 and is provided with a scraper portion that is raised relative to the second baffle 3. A driving mechanism 5 is connected to the first baffle 2 to drive the bottom first baffle 2 to shield the discharge port.

[0031] It can be understood that the scraping part on the second baffle 3 is facing the discharge port of the silo feeder. When the driving mechanism 5 drives the first baffle 2 to close the discharge port, the scraping part will directly contact the material 10. When the driving mechanism 5 drives the first baffle 2 to move to open the discharge port, the scraping part moves with the first baffle 2 and scrapes the material 10 at the discharge port, thereby changing the accumulation state of the material 10 at the discharge port, so that the material 10 at the discharge port is no longer in a stable state, and can then flow out of the discharge port smoothly. Even when the driving mechanism 5 drives the first baffle 2 to move for the first time to open the discharge port, the material 10 scraped by the scraper part is not enough to solve the problem of the blockage of the material 10 at the discharge port. The driving mechanism 5 reciprocates and drives the first baffle 2 to move back and forth on the bracket 1. After the scraper part reciprocates with the first baffle 2, it can continuously scrape the material 10 at the discharge port. After part of the material 10 is scraped off from the blocked discharge port, the structure between the blocked materials 10 changes. Under the action of gravity and the thrust of the scraper part, the material 10 at the blocked place collapses and slides. The material 10 in the hopper can fall smoothly, and the discharge port will become unobstructed. For most of the materials 10 that can cause the discharge port to be blocked, the blocking device can easily dredge the discharge port, reduce the frequency of manual dredging, and improve the distribution efficiency.

[0032] Of course, in some embodiments, the bracket 1 can be directly set on the silo feeder, so that the scraping part on the second baffle 3 can be partially located in the discharge port of the silo feeder, which can be used to clear the discharge port of the feeder.

[0033] See also Figure 1 and Figure 2 The bracket 1 has a first side surface and a second side surface relative to each other. The first side surface of the bracket 1 is provided with a slide groove 9. The first baffle 2 is slidably provided on the first side surface of the bracket 1, and the first baffle 2 is provided with a slider that can slide with the slide groove 9.

[0034] The first baffle 2 is slidably engaged with the slide block and the chute 9, so that the first baffle 2 can slide on the bracket 1. The second side of the bracket 1 faces the discharge port of the silo feeder. Therefore, the chute 9 is arranged on the first side of the bracket 1 to effectively prevent the splashing material 10 from falling into the chute 9 and affecting the movement of the first baffle 2.

[0035] See also Figure 1 and Figure 2 The drive mechanism 5 and the first baffle 2 are connected by a connector 6. The connector 6 makes the output shaft of the drive mechanism 5 and the first baffle 2 non-rigidly connected, thereby reducing the possibility of the output shaft of the drive mechanism 5 being disconnected from the first baffle 2 during the process of driving the first baffle 2 to reciprocate, reducing the failure rate of the material blocking device and increasing the service life of the material blocking device.

[0036] In some embodiments, the end of the driving mechanism 5 has a first ring and a second ring arranged coaxially, and the end of the first baffle 2 is provided with a third ring, and the connecting member 6 is a bolt, which connects the first ring, the third ring and the second ring, that is, the third ring is located between the first ring and the second ring, and the plug of the bolt is against the first ring, and the nut is screwed to the bolt and then against the second ring, so that the first ring, the third ring and the second ring are pivotally connected. The kinetic energy of the material 10 during flow will cause a deviation in the force applied to the first baffle 2 and the output shaft, which makes it easy for the first baffle 2 and the output shaft of the driving mechanism 5 to be misaligned. At this time, since the first ring, the third ring and the second ring are pivotally connected, the output shaft of the driving mechanism 5 and the first baffle 2 can rotate relative to each other, that is, the displacement difference between the output shaft of the driving mechanism 5 and the first baffle 2 can be eliminated, further reducing the possibility of damage to the material blocking device.

[0037] In some embodiments, the driving mechanism 5 can be a motor, which is connected to an output shaft through a gear box to drive the output shaft to move along the direction of the slide 9; of course, the driving mechanism 5 can also be a hydraulic mechanism or a pneumatic mechanism, and the output shaft of the hydraulic mechanism or the pneumatic mechanism is arranged along the length direction of the slide 9, and the cylinder body of the hydraulic mechanism or the pneumatic mechanism is arranged on the outer wall of the feeder or other positions that can keep the cylinder body and the bracket 1 relatively stationary.

[0038] See also Figure 3-Figure 6 In some embodiments, the bracket 1 has a first side surface and a second side surface opposite to each other, the scraping portion is located on the side surface where the second baffle 3 and the second side surface of the bracket 1 are on the same side, and the scraping portion includes a plurality of scraping members 4 .

[0039] Specifically, the second baffle 3 can be detachably arranged on the first baffle 2. Thus, when the second baffle 3 is installed on the first baffle 2 and the material blocking device is in operation, the scraping part is located on the side of the second baffle 3 and the second side of the bracket 1, so that the material blocking part can be located in the discharge port.

[0040] See also Figure 3 In some embodiments, the scraper 4 is a columnar member, one end of the scraper 4 is fixedly connected to the second baffle 3, and the other end of the scraper 4 is inclined toward the driving mechanism 5.

[0041] The scraper 4 is a columnar member with gaps between adjacent columns, allowing the scraper 4 to penetrate into the clogged material 10 and scrape the material 10 more efficiently. The other end of the scraper 4 is tilted relative to the drive mechanism 5. This allows the scraper column to smoothly penetrate the clogged material 10 when moving in one direction, and to move the material 10 when moving in the opposite direction, making it less susceptible to damage.

[0042] See also Figure 4 In some embodiments, the scraper 4 includes a first rod and a second rod, one end of the first rod is fixedly connected to the second baffle 3, the other end of the first rod is fixedly connected to one end of the second rod, and the other end of the second rod is also inclined toward the driving mechanism 5; the angle between the first rod and the second rod is an obtuse angle.

[0043] It can be understood that at this time the scraper 4 also has a partial structure that is tilted so that the end of the scraper 4 away from the second baffle 3 can more smoothly extend into the material 10, changing the structure of the material 10 blocked at the discharge port, so that after the first baffle 2 opens the discharge port, the loosened material 10 can flow out of the discharge port.

[0044] See also Figure 5 and Figure 6 In some embodiments, the scraper 4 is in the shape of a triangular pyramid.

[0045] Specifically, the cross-sectional area of the triangular pyramid-shaped scraper 4 gradually decreases in the direction away from the second baffle 3, that is, the tip of the scraper 4 is toward the discharge port of the hopper feeder. At this time, the scraper 4 can be more easily inserted into the blocked material 10, and the three side edges of the triangular pyramid-shaped scraper 4 are also sharp. In the process of the second baffle 3 moving back and forth with the first baffle 2, at least one side edge of the scraper 4 can contact the material 10, extend into or scrape the material 10.

[0046] In some embodiments, one of the edges of the scraper 4 faces the side away from the driving mechanism. Specifically, when the driving mechanism 5 drives the first baffle 2 to approach and close the discharge port, one edge of the scraper 4 will be inserted into the material 10 along the direction of movement of the first baffle 2. When the driving mechanism 5 drives the first baffle 2 away from the discharge port and opens the discharge port, the side of the scraper 4 will push the material 10 to move, thereby loosening the material 10 at the discharge port, and the blockage clearing effect is good.

[0047] See also Figure 1 and Figure 6 The second baffle 3 is a dovetail plate with a dovetail groove 8 at one end. The first baffle 2 is equipped with a dovetail buckle 7 that matches the dovetail groove 8. The dovetail buckle 7 engages within the dovetail groove 8, ensuring self-locking of the second baffle 3 and facilitating easy replacement. Operators regularly inspect and replace the second baffle 3 if the scraper 4 on the second baffle 3 exhibits significant deformation. Of course, if the type, size, viscosity, or other characteristics of the material 10 discharged from the silo feeder change, the second baffle 3 can be replaced with a different type of scraper 4 to facilitate specific blockage clearing operations for different materials 10.
