Description

Technical Field

[0001] The utility model relates to the technical field of garbage recycling and processing, in particular to a drum screening machine for garbage processing. Background Art

[0002] A garbage screening machine is a device that separates and discharges the dumped garbage according to its diameter.

[0003] With the acceleration of industrialization and urbanization, the construction industry has also developed rapidly, and the amount of construction waste generated is increasing. Construction waste mainly includes bricks and soil. Smaller materials can be used for paving roads, and larger particles can also be used after being crushed. The existing garbage screening machine rotates the drum to make the poured garbage flip and roll, and leak out from holes of different diameters to achieve a screening effect. However, the following problems exist during use: when construction waste particles pass through the sieve holes, due to the different shapes of the particles, it is easy for the edges of the particles to rub against the inner wall of the sieve holes, and thus get stuck in the sieve holes. When subsequent particles fall into this sieve hole, they are blocked by the stuck particles, affecting the screening efficiency of the screening machine. Utility Model Content

[0004] In order to solve the above problems, the purpose of the present invention is to provide a drum screening machine for garbage disposal, which aims to solve the problem that the screen holes in the drum screening barrel are blocked and affect the screening efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A drum screening machine for garbage disposal comprises a base, a screening drum rotatably and tiltably mounted on the base, a discharge port movably connected to the upper end of the screening drum and with a feed port pointing vertically upward, a discharge port provided at the lower end of the screening drum, a plurality of screen hole groups provided on the outer peripheral wall of the screening drum, a plugging assembly provided on the upper outer wall of the screening drum and used to push out garbage particles blocked in the screen hole groups, and a vibrating assembly provided in the screening drum and used to crush the garbage particles; the screen hole groups are arranged at intervals in the circumferential direction and extend along the length of the screening drum;

[0007] The sieve hole group is composed of a number of sub-holes arranged at intervals along the length direction of the sieve drum;

[0008] The plugging assembly includes a placement box arranged just above the drum screen and along the length direction of the drum screen, a plurality of sliding posts corresponding to each sub-hole and sliding in the vertical direction, a through-hole portion arranged at the lower end of the sliding post and extending into the sub-hole, a spring arranged between the upper end of the sliding post and the placement box, and a protrusion arranged between adjacent sieve hole groups on the outer wall of the screening drum and used to push the sliding post upward into the placement box;

[0009] The thickness of the projection gradually increases along the rotation direction of the screening drum, and the edge of the thickest part of the projection is tangent to the sub-hole.

[0010] More preferably, a spherical slider is provided on the side of the through hole portion that first contacts the bump.

[0011] More preferably, an anti-slip plate is fixedly provided on the upper end of the sliding column, and the anti-slip plate abuts against the bottom of the inner wall of the placement box.

[0012] More preferably, the vibration assembly includes a rotating rod provided in the screening drum along the length direction of the screening drum, a plurality of crushing columns symmetrically arranged at intervals on the left and right sides of the rotating rod, and a control motor provided at the upper end of the rotating rod and used to drive the rotating rod to rotate repeatedly left and right;

[0013] The upper end of the rotating rod passes through the discharge port and is axially fixedly connected to the output shaft of the control motor, and the control motor is fixedly connected to the base.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model solves the problem of clogging of the screen holes in the drum screening drum by causing particles to get stuck in the sub-holes during the rotation of the drum screening drum. When the sub-holes rotate upward, the plug part slides out from the placement box and extends into the sub-holes, impacting the particles in the sub-holes. As a result, the stuck particles are impacted and fall into the screening drum, thus solving the problem of clogging of the screen holes in the drum screening drum.

[0017] 2. The utility model drives the crushing column to swing up and down by repeatedly rotating the rotating column back and forth. When the clogged particles are knocked out of the sub-hole, they enter the screening cylinder and collide with the crushing column, causing the particles to be partially broken by the impact, resulting in the particles being broken. As a result, the particles that failed to pass through the sub-hole smoothly for the first time can pass through the sub-hole smoothly after secondary crushing. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 、 Figure 2 and Figure 3 As shown, a drum screening machine for garbage disposal in this embodiment includes a base 1, a screening drum 2 rotatably and tiltably mounted on the base 1, a discharge port 3 movably connected to the upper end port of the screening drum 2 and with a feed port vertically upward, a discharge port 4 provided at the lower end port of the screening drum 2, a plurality of sieve hole groups 5 provided on the outer peripheral wall of the screening drum 2, a discharging assembly 6 provided on the upper outer wall of the screening drum 2 and used for pushing out garbage particles blocked in the sieve hole groups 5, and a vibrating assembly 7 provided in the screening drum 2 and used for crushing garbage particles; the sieve hole groups 5 are arranged at intervals in the circumferential direction and extend along the length direction of the screening drum 2;

[0025] The sieve hole group 5 is composed of a number of sub-holes 51 arranged at intervals along the length direction of the sieve drum 2;

[0026] The plugging assembly 6 includes a placement box 61 provided just above the drum screen and arranged along the length direction of the drum screen, a plurality of sliding posts 62 corresponding one to each sub-hole 51 and sliding in the vertical direction, a through-hole portion 63 provided at the lower end of the sliding post 62 and extending into the sub-hole 51, a spring 65 provided between the upper end of the sliding post 62 and the placement box 61, and a protrusion 66 provided between adjacent sieve hole groups 5 on the outer wall of the screening drum 2 and used to push the sliding post 62 upward into the placement box 61;

[0027] The thickness of the projection 66 gradually increases along the rotation direction of the screening drum 2 , and the edge of the thickest part of the projection 66 is tangent to the sub-hole 51 .

[0028] When this product is in use, the garbage particles entering the screening drum 2 from the discharge port 3 are affected by the centrifugal force and downward gravity in the circumferentially rotating and inclined screening drum 2, causing the particles to rotate and flip in the screening drum 2, and gradually move toward the discharge port 4 of the screening drum 2. When the particles rotate to the sub-hole 51 that matches its diameter, the particles fall into the sub-hole 51 and enter the storage box. Some of the particles stuck in the sub-hole 51, in the process of rotating to the top, the through-hole portion 63 slides upward along the surface path of the protrusion 66, causing the spring 65 to be compressed, and when the sub-hole 51 rotates to the top, the through-hole portion 63 slides downward along the edge of the protrusion 66, and under the action of the elastic restoring force of the spring 65, it impacts the particles in the sub-hole 51 downward, thereby knocking the particles in the sub-hole 51 into the screening drum 2, thereby solving the problem of the screen holes in the drum screening drum being blocked and affecting the screening efficiency.

[0029] When this product is in use, after the through-hole portion 63 pushes out the particles in the sub-hole 51, the screening drum 2 continues to rotate in the rotation direction A, so that the through-hole portion 63 slides along the surface path of the protrusion 66. As the screening drum 2 rotates, the sliding column 62 continues to slide upward, so that the sliding column 62 shrinks into the placement box 61, causing the spring 65 to be compressed, prompting the sliding column 62 to have a larger impact potential energy after it breaks away from the obstruction of the protrusion 66, so that the blocked particles are knocked out.

[0030] like Figure 2 As shown, a spherical slider 631 is provided on the side of the through hole portion 63 that first contacts the protrusion 66 .

[0031] When this product is in use, after the through-hole portion 63 pushes out the particles in the sub-hole 51, the screening drum 2 continues to rotate in the rotation direction A, so that the side of the through-hole portion 63 provided with the spherical slider 631 first comes into contact with the outer wall of the screening drum 2. Since the surface of the spherical slider 631 is smooth, there will be no jamming when the through-hole portion 63 slides out of the sub-hole 51 and slides along the surface of the protrusion 66.

[0032] like Figure 2 As shown, an anti-slip plate 621 is fixedly provided on the upper end of the sliding column 62 , and the anti-slip plate 621 abuts against the bottom of the inner wall of the placement box 61 .

[0033] When this product is in use, after the sliding column 62 slides downward and extends out of the placement box 61, the through-hole portion 63 extends into the sub-hole 51, pushing out the particles, and the anti-fall-off plate 621 abuts against the bottom of the inner wall of the placement box 61 to prevent the sliding column 62 from falling off from the placement box 61 and falling into the screening cylinder 2.

[0034] like Figure 1 、 Figure 2 and Figure 3As shown, the vibration assembly 7 includes a rotating rod 71 provided inside the screening drum 2 along the length direction of the screening drum 2, a plurality of crushing columns 72 symmetrically arranged on the left and right sides of the rotating rod 71, and a control motor 73 provided at the upper end of the rotating rod 71 for driving the rotating rod 71 to rotate repeatedly left and right;

[0035] The upper end of the rotating rod 71 passes through the discharge port 3 and is axially fixedly connected to the output shaft of the control motor 73 , and the control motor 73 is fixedly connected to the base 1 .

[0036] When this product is in use, the particles that are impacted into the screening cylinder 2 come into contact with the crushing column 72, and the continuously swinging crushing column 72 collides with the falling particles of the through-hole portion 63 to impact each other, thereby performing secondary crushing on the particles. After the secondary crushing by the vibration component 7, the particles can smoothly fall out of the sub-hole 51, and by controlling the motor 73 to continuously drive the rotating rod 71 to rotate back and forth, the entire device will be vibrated, so that some particles stuck in the sub-hole 51 fall out by themselves under the influence of vibration, further preventing the particles from being blocked in the sieve hole group 5.

[0037] like Figure 1 and Figure 4 As shown, a limiting track 8 is provided at the upper end of the screening drum 2 , and a limiting ring 9 is provided at the lower end of the discharge port 3 and is embedded in the limiting track 8 and slidably arranged.

[0038] When this product is in use, the limiting ring 9 at the lower end of the discharge port 3 is embedded in the limiting track 8 and is slidably arranged, so that when the screening drum 2 rotates, the discharge port 3 remains open in a vertically upward state, which is convenient for the operator to continuously add garbage particles that need to be screened.

[0039] The working principle of this device is:

[0040] The first step: start the device to rotate the screening drum 2 along the axis, control the motor 73 to drive the rotating column 71 to rotate repeatedly, and pour the crushed garbage into the discharge port 3.

[0041] Step 2: The garbage particles entering the screening drum 2 from the discharge port 3 are affected by the centrifugal force and downward gravity in the circumferentially rotating and inclined screening drum 2, causing the particles to rotate and flip in the screening drum 2, and gradually move toward the discharge port 4 of the screening drum 2. When the particles rotate to the sub-hole 51 that matches its diameter, the particles fall into the sub-hole 51 and enter the storage box.

[0042] Step 3: When some particles stuck in the sub-hole 51 rotate to the top, the through-hole portion 63 slides upward along the surface path of the protrusion 66, causing the spring 65 to be compressed. When the sub-hole 51 rotates to the top, the through-hole portion 63 slides downward along the edge of the protrusion 66, and under the action of the elastic restoring force of the spring 65, it impacts downward to hit the particles in the sub-hole 51, thereby knocking the particles in the sub-hole 51 into the screening drum 2.

[0043] Step 4: The sub-hole 51 continues to rotate, the spherical slider 631 abuts against the outer wall of the screening drum 2 and slides upward along the thickness direction of the protrusion 66, so that the through-hole portion 63 is separated from the sub-hole 51 and retracts into the placement box 61 again.

[0044] Step 5: The particles that are knocked into the screening cylinder 2 come into contact with the crushing column 72. The continuously swinging and rotating crushing column 72 collides with the falling particles in the through-hole portion 63, thereby crushing the particles for the second time. After the particles are crushed for the second time by the vibration component 7, they can fall out of the sub-hole 51 smoothly.

[0045] Step 6: Garbage with particles that are too large will be discharged from the discharge port 4 after passing through the screening drum 2.

[0046] The above description is only a specific embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
