Description

Technical Field

[0001] The utility model relates to the technical field of garbage disposal, in particular to a crusher with internal self-cleaning function. Background Art

[0002] The crusher is a machine that crushes the garbage into pieces after it is poured in, thus facilitating subsequent recycling operations.

[0003] When crushing plastic and other garbage items, there are the following problems:

[0004] 1. Plastic products often contain moisture. After being crushed, the moisture in the plastic splashes out, causing the inner wall of the crusher to become damp. When the plastic fragments come into contact with moisture, they will stick together. As a result, a large amount of plastic fragments often accumulate on the inner wall of the crusher during the crushing process, resulting in plastic fragments remaining on the inner wall of the crusher. After the crushing is completed, the inner wall needs to be cleaned manually, causing inconvenience in use.

[0005] 2. As plastic products are light in weight, when they touch the cutter group, they are affected by the rotational force of the rotating blades and fly up, and cannot be directly crushed by the cutter group, which reduces the working efficiency of the crusher. Utility Model Content

[0006] In order to solve the above problems, the purpose of the present invention is to provide a crusher with internal self-cleaning, which aims to solve the problem that garbage is easily adhered to the inner wall of the crusher.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A crusher with internal self-cleaning, comprising a base, a casing fixedly mounted on the base, a discharge port at the bottom of the casing, a collection box located below the discharge port and opening upward for collecting crushed garbage, a feed port located on the left side of the middle portion of the casing, a movable blade assembly disposed within the casing for crushing garbage, a scraper assembly movably disposed within the casing in a height direction for pushing debris remaining on the inner wall of the casing into the movable blade assembly, and a pushing assembly disposed on the scraper assembly for pushing garbage within the casing toward the movable blade assembly.

[0009] The scraper assembly includes a scraper sleeve movably sleeved in the casing along the height direction of the casing, a pair of fixed screws fixedly arranged on opposite sides of the upper end of the scraper sleeve, and a pair of stepper motors fixedly arranged in the upper part of the casing corresponding to the fixed screws on both sides and used to move the fixed screws upward or downward;

[0010] The pushing assembly includes a pressing plate rotatably arranged on the right inner wall of the scraping sleeve, a pushing rod horizontally arranged below the pressing plate, and a driving subassembly arranged on the inner side of the scraping sleeve and used to drive the pushing rod to rotate the pressing plate to a horizontal state;

[0011] The driving subassembly includes two sets of sprocket chain mechanisms respectively installed on the front and rear inner walls of the scraper sleeve, and a control motor fixed on the inner wall of the scraper sleeve away from the feeding port and used to drive the sprocket chain mechanisms on both sides to rotate;

[0012] More preferably, the control motor output shaft is axially fixedly connected to the rotating shaft of the driving sprocket in the sprocket chain mechanism.

[0013] More preferably, the pressing plate is provided with an air avoidance groove directly above the control motor for preventing the pressing plate from abutting against the control motor.

[0014] More preferably, the output end of the stepper motor is threadedly connected to a fixed screw rod, and the fixed screw rod passes through the stepper motor and the upper end surface of the housing.

[0015] More preferably, a pair of limit blocks are fixedly provided on opposite sides of the upper surface of the scraping sleeve at one end close to the free end of the pressing plate, and the limit blocks abut against the upper surface of the free end of the pressing plate.

[0016] More preferably, an elastic sealing ring is fixedly provided on the side wall of the scraping sleeve.

[0017] More preferably, the movable knife assembly includes a pair of cutting knives rotatably arranged at the lower end of the casing, a pair of rotating gears meshing and rotatably arranged on the outer wall of the casing, and a driving motor fixed on the base and used to drive the rotating gears to rotate.

[0018] The utility model has the following beneficial effects:

[0019] 1. The utility model pours garbage into the feed port, and the garbage is crushed by the moving knife assembly. The garbage splashed by the pressure sticks to the inner wall of the casing, and the stepper motor is started to slide the fixed screw rod downward, causing the scraper sleeve to slide downward along the inner wall of the casing and scrape the garbage remaining on the inner wall of the casing into the moving knife assembly, thereby solving the problem of garbage easily sticking to the inner wall of the crusher.

[0020] 2. The utility model drives the push rod to slide toward the free end of the pressing plate after the scraper sleeve slides to the upper end of the casing, prompting the pressing plate to rotate upward to a horizontal state. At this time, the stepper motor drives the scraper sleeve to slide downward, so that in the process of the scraper sleeve sliding down, the pressing plate is prompted to abut against the garbage poured into the casing and apply a thrust toward the movable knife assembly to the garbage, thereby solving the problem that the garbage will fly up when it contacts the movable knife assembly, resulting in reduced crushing efficiency.

[0029] The following is a further detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments.

[0030] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 7 As shown, an internal self-cleaning crusher of this embodiment includes a base 1, a casing 11 fixedly arranged on the base 1, a discharge port 2 provided at the bottom of the casing 11, a collection box 21 provided below the discharge port 2 and opening upward for collecting crushed garbage, a feed port 3 provided on one side of the middle part of the casing 11, a movable blade assembly 4 provided in the casing 11 and used for crushing garbage, a scraping assembly 5 movably provided in the casing 11 along the height direction and used for pushing debris remaining on the inner wall of the casing 11 into the movable blade assembly 4, and a pushing assembly 6 provided on the scraping assembly 5 and used for pushing garbage in the casing 11 toward the movable blade assembly 4;

[0031] The scraper assembly 5 includes a scraper sleeve 51 that is movably mounted in the housing 11 along the height direction of the housing 11, a pair of fixed screws 52 fixed to opposite sides of the upper end of the scraper sleeve 51, and a pair of stepper motors 53 fixed to the upper part of the housing 11 corresponding to the fixed screws 52 on both sides and used to move the fixed screws 52 upward or downward.

[0032] The pushing assembly 6 includes a pressing plate 61 rotatably mounted on the right inner wall of the scraping sleeve 51, a pushing rod 62 horizontally mounted below the pressing plate 61, and a driving subassembly 63 mounted inside the scraping sleeve 51 and used to drive the pushing rod 62 to rotate the pressing plate 61 to a horizontal position.

[0033] The driving subassembly 63 includes two sets of sprocket chain mechanisms 631 respectively installed on the front and rear inner walls of the scraper sleeve 51, and a control motor 633 fixed on the inner wall of the scraper sleeve 51 away from the feed port 3 and used to drive the sprocket chain mechanisms 631 on both sides to rotate;

[0034] The push rod 62 is fixed between the sprocket chain mechanisms 631 on both sides, and the output shaft of the control motor 633 is axially fixedly connected to the rotating shaft of the driving sprocket in the sprocket chain mechanism 631 .

[0035] When the product is in use, the garbage to be crushed is poured into the interior of the casing 11 from the feed port 3, and then the stepper motor 53 is used to rotate the output end of the stepper motor 53, thereby driving the fixed screw rod 52 connected to the stepper motor 53 to slide upward, thereby driving the scraper sleeve 51 to slide upward to the upper part of the casing 11, and then starting the control motor 633 to rotate the sprocket chain mechanism 631 and drive the push rod 62 to move to the upper left, causing the push rod 62 to push the free end of the pressing plate 61 upward, thereby causing the pressing plate 61 to rotate upward to a horizontal state. At this time, the stepper motor 53 is started in the reverse direction, causing the stepper motor 53 to drive the fixed screw rod 52 The scraper sleeve 51 moves downward, thereby driving the scraper sleeve 51 to slide downward. As the scraper sleeve 51 slides downward, the scraper sleeve 51 abuts against the inner wall of the casing 11, thereby pushing the garbage fragments remaining on the inner wall of the casing 11 downward until they are pushed to the movable knife assembly 4, thereby scraping off the garbage remaining on the inner wall of the casing 11 and sending it into the movable knife assembly 4 at the bottom for crushing, solving the problem that garbage is easily adhered to the inner wall of the crusher, and when the scraper sleeve 51 slides downward, the pressing plate 61 abuts against the top of the garbage in the casing 11 and continuously applies a thrust toward the movable knife assembly 4 to the garbage, thereby solving the problem that garbage is easy to fly when crushed.

[0036] like Figure 6 and Figure 7 As shown, a clearance groove 7 is provided on the pressing plate 61 just above the control motor 633 to prevent the pressing plate 61 from abutting against the control motor 633 .

[0037] When this product is in use, when the push rod 62 moves to the lower right, the pressing plate 61 is affected by the pressure of the newly poured garbage from above and its own gravity, prompting the pressing plate 61 to rotate downward, and during the rotation, the control motor 633 is extended along the air avoidance groove 7, thereby preventing the pressing plate 61 from being affected by the control motor 633 and being restricted in rotation. In the process of the scraper sleeve 51 sliding down to press the garbage, the control motor 633 blocks most of the holes in the air avoidance groove 7, preventing large pieces of garbage that are easy to fly out from the air avoidance groove 7, which affects the crushing efficiency.

[0038] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the output end of the stepper motor 53 is threadedly connected to the fixed screw 52, ​​and the fixed screw 52 passes through the stepper motor 53 and the upper end surface of the housing 11.

[0039] When this product is in use, the direction of the current of the stepping motor 53 is controlled to change the direction of rotation of the output end of the stepping motor 53, so that the fixed screw rod 52 threadedly connected to the stepping motor 53 changes its movement direction along with the rotation direction of the output end of the stepping motor 53, thereby meeting the use of this device.

[0040] like Figure 3 and Figure 6 As shown, a pair of limit blocks 8 are fixedly provided on opposite sides of the upper surface of the scraping sleeve 51 at one end close to the free end of the pressing plate 61 , and the limit blocks 8 abut against the upper surface of the free end of the pressing plate 61 .

[0041] When this product is in use, when the pressing plate 61 abuts against the upper end of the garbage and continuously presses down the internal garbage, the garbage exerts an upward reaction force on the pressing plate 61. The setting of the limit block 8 prevents the pressing plate 61 from turning upward and outward, causing the garbage to overflow.

[0042] like Figure 3 As shown, an elastic sealing ring 9 is fixedly provided on the side wall of the scraping sleeve 51 .

[0043] When the product is in use, the elastic sealing ring 9 is provided to scrape off the residual water droplets on the inner wall and the liquid that may cause retention of garbage fragments as the scraping sleeve 51 slides.

[0044] like Figure 1 and Figure 2 As shown, the movable knife assembly 4 includes a pair of cutting knives 41 rotatably arranged at the lower end of the casing 11, a pair of rotating gears 42 meshing and rotatably arranged on the outer wall of the casing 11, and a driving motor 43 fixed on the base 1 and used to drive the rotating gears 42 to rotate.

[0045] When the product is in use, the driving motor 43 rotates, thereby transmitting the rotational force at its output end to one of the rotating gears 42, causing a pair of mutually meshing rotating gears 42 to mesh and rotate, thereby driving the two cutting blades 41 to rotate in opposite directions. As a result, the garbage entering the cutting blades 41 is cut while also subjected to the inward crushing pressure of the cutting blades 41, thereby accelerating the efficiency of garbage crushing.

[0046] The working principle of this device is:

[0047] The first step: start the stepper motor 53 to rotate, thereby driving the fixed screw 52 threadedly connected to the stepper motor 53 to slide upward, prompting the fixed screw 52 to drive the scraper sleeve 51 to slide upward until the scraper sleeve 51 moves to the top of the housing 11.

[0048] Step 2: The operator pours the garbage into the casing 11 along the feeding port 3, and starts the control motor 633 at the same time, so that the control motor 633 drives the sprocket chain mechanism 631 to rotate, so that the push rod 62 fixedly connected to the sprocket chain mechanism 631 moves synchronously with the motion trajectory of the sprocket chain mechanism 631 chain, so that when the push rod 62 moves to the upper left along the motion trajectory of the sprocket chain mechanism 631, the push rod 62 remains in contact with the bottom of the pressing plate 61 and rotates the pressing plate 61 upward until the pressing plate 61 rotates to a horizontal state.

[0049] Step 3: Start the stepper motor 53 and make the stepper motor 53 rotate in the opposite direction, thereby driving the fixed screw rod 52 to slide downward, prompting the scraper sleeve 51 to drive the pressing plate 61 to slide downward together, so that the scraper sleeve 51 slides downward along the inner wall of the casing 11, thereby scraping the residual garbage on the inner wall of the casing 11 and pushing it downward into the movable knife assembly 4, crushing the residual garbage and discharging it from the discharge port 2, and applying a thrust toward the movable knife assembly 4 to the garbage in the casing 11, thereby accelerating the crushing efficiency.

[0050] Step 4: After the scraper sleeve 51 slides to the movable knife assembly 4, the current direction of the stepper motor 53 is changed, thereby causing the output end of the stepper motor 53 to rotate in the opposite direction, thereby driving the fixed screw rod 52 to slide upward, and at the same time controlling the motor 633 to continue to drive the sprocket chain mechanism 631 to rotate, so that the push rod 62 continues to slide to the lower right, causing the bottom of the pressing plate 61 to lose the abutment force of the push rod 62, and rotate downward under the influence of the newly poured garbage and its own gravity, so that the newly poured garbage is not blocked by the pressing plate 61, and moves along the opening toward the movable knife assembly 4 for crushing.

[0051] Step 5: After the scraping sleeve 51 slides to the upper part of the casing 11, repeat the second to fourth steps to perform cyclic crushing and ensure that no crushed garbage remains on the inner wall of the casing 11.

[0052] 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.
