DETAILED DESCRIPTION

[0029] See also Figure 1-Figure 10 In the embodiment of the present invention, the self-unloading ore truck includes a hopper 1 and a support assembly 2. The hopper 1 is assembled on the support assembly 2. A driving cylinder 11 is installed on the support assembly 2. A slider 7 is rotatably arranged on the top of the driving cylinder 11. A mounting groove slidably connected to the slider 7 is arranged at the bottom center of the hopper 1. A scraper rod 3 is slidably arranged in the hopper 1. The top of the scraper rod 3 is slidably connected to the hopper 1. A driving assembly is arranged at the end of the hopper 1. When the slider 7 moves toward the driving assembly, the slider 7 drives the scraper rod 3 to move in the hopper 1 in a direction away from the driving assembly through the driving assembly.

[0030] Preferably, the support assembly 2 includes a base; a support plate is fixedly provided at one end of the top of the base symmetrically along the center, the top of the support plate is rotatably connected to both sides of one end of the hopper 1, the driving cylinder 11 is installed at the center of the bottom plate, and a rotating wheel is installed at the bottom of the bottom plate, and a pad is fixedly provided at the end of the top of the bottom plate away from the support plate, and the pad is slidably fitted with the bottom of the hopper 1, the side wall of the hopper 1 close to the pad is a vertical structure, and the side wall of the hopper 1 at the end away from the pad is an inclined structure. When unloading, the hopper 1 is deflected so that the material in the hopper 1 is unloaded from its inclined side. In actual use, in the initial state, the scraper rod 3 is at the end of the hopper 1 away from the support plate, and the bottom of the end of the hopper 1 away from the support plate is connected to the pad. The hopper 1 is fitted with materials, and then when the hopper 1 is filled with materials, the hopper 1 is moved to the unloading position by the rotating wheel and braked, and then the output end of the driving cylinder 11 is started to extend, and the output end of the driving cylinder 11 is extended to make the slider 7 move upward, and through the cooperation of the slider 7 and the slide groove and the restriction of the hopper 1 by the support plate, the hopper 1 can be rotated around the rotating connection with the support plate, thereby completing the dumping of materials. When the slider 7 moves in the installation groove to one end close to the driving assembly, the hopper 1 is deflected to the maximum angle, and then the driving assembly drives the scraper rod 3 to move in the hopper 1 toward the support plate, to achieve the scraping and cleaning of the inner wall of the hopper 1, avoiding the attachment of materials to the inner wall of the hopper 1, thereby affecting the next material filling work.

[0031] See also Figure 1-Figure 6 Preferably, guide grooves 8 are provided on both sides of the top of the hopper 1, and connecting plates slidably connected to the guide grooves 8 are provided on both sides of the top of the scraper rod 3. A telescopic tube 31 is provided at one end of the connecting plate close to the driving assembly, and the end of the telescopic tube 31 away from the connecting plate is connected to the driving assembly. In actual use, in the initial state, the scraper rod 3 is at one end of the guide groove 8 close to the driving assembly, that is, the scraper rod 3 is as a whole in one end of the hopper 1 close to the driving assembly, and is in contact with the inner wall of the hopper 1 close to the driving assembly. In this way, when the hopper 1 is loaded with materials, the side of the scraper rod 3 close to the driving assembly will not be stuck between the scraper rod 3 and the material due to the existence of a gap. The problem between the hopper 1 is solved, so as to facilitate the subsequent unloading. When the hopper 1 is unloaded, the driving cylinder 11 is started to make the hopper 1 deflect and unload. In this process, the slider 7 slides toward the driving assembly in the installation groove, so that the driving assembly accumulates force. Then, when the slider 7 moves to the maximum distance in the installation groove, the driving assembly triggers the telescopic tube 31 to expand toward the connecting plate, and then the connecting plate moves in the direction of the hopper 1 unloading, and then the scraper rod 3 moves in the direction of the hopper 1 unloading, and the scraper rod 3 is used to complete the cleaning of the inner wall of the hopper 1, so as to avoid the presence of attached materials on the inner wall that requires separate cleaning by personnel.

[0032] See also Figure 3-Figure 6The driving assembly includes a fixed box 4; the fixed box 4 is a hollow structure, a protrusion is provided in the middle of the fixed box 4, a piston plate 45 and an auxiliary plate 43 are slidably provided in the fixed box 4, the piston plate 45 is provided above the protrusion, the auxiliary plate 43 is slidably provided below the protrusion, and the piston plate 45 is sealed and slidably connected to the inner wall of the fixed box 4, a liquid storage chamber 41 is provided between the top of the piston plate 45 and the fixed box 4, an active chamber 42 is provided between the auxiliary plate 43 and the protrusion, an end of the telescopic tube 31 away from the connecting plate is connected to the liquid storage chamber 41 through a connecting tube, a spring is provided between the auxiliary plate 43 and the piston plate 45, and in actual use, a driving liquid is provided in the liquid storage chamber 41, and the driving liquid can be driving oil or other similar liquids. In the initial state, the bottom of the piston plate 45 is in contact with the top of the protrusion, and the auxiliary plate 43 is in contact with the piston plate 45. The plate 43 is at the bottom of the active chamber 42, the telescopic tube 31 is in a retracted state, and the scraper rod 3 is in a position in the hopper 1 near the fixed box 4; when the auxiliary plate 43 moves upward, the auxiliary plate 43 pushes the piston plate 45 upward through the spring, and the piston plate 45 moves upward so that the driving liquid in the liquid storage chamber 41 is transported to the telescopic tube 31 through the connecting tube, thereby causing the telescopic tube 31 to expand. The expansion of the telescopic tube 31 pushes the connecting plate to move the scraper rod 3 in the hopper 1, and when the auxiliary plate 43 moves downward, it drives the piston plate 45 to move downward and reset. The movement and reset of the piston plate 45 generates negative pressure in the liquid storage chamber 41, thereby causing the driving liquid in the telescopic tube 31 to be transported back to the liquid storage chamber 41 through the connecting tube, thereby causing the telescopic tube 31 to contract and reset, and then the scraper rod 3 moves and resets.

[0033] Further, preferably, a first pull rope 46 is fixedly provided on the top of the auxiliary plate 43, a first round rod is fixedly provided on one end of the mounting groove away from the fixing box 4, the first round rod is arranged on one end of the slider 7 away from the fixing box 4, one end of the first pull rope 46 away from the auxiliary plate 43 passes through the side wall of the fixing box 4 and extends to the end of the mounting groove away from the fixing box 4, and one end of the first pull rope 46 away from the auxiliary plate 43 bypasses the first round rod and is fixedly connected to the end of the slider 7. In actual use, a wire groove for sliding the first pull rope 46 is provided on the side wall of the hopper 1, and the bottom end of the wire groove is connected to the mounting groove, which facilitates the sliding of the first pull rope 46. When the output end of the driving cylinder 11 is started upward, During output, the output end of the driving cylinder 11 pushes the slider 7 to move upward, thereby causing the hopper 1 to deflect and unload with the support plate as the center. When the hopper 1 deflects, the slider 7 will slide in the direction of the next fixed box 4 in the installation groove. At this time, the sliding of the slider 7 pulls the first pull rope 46, thereby causing the auxiliary plate 43 to move upward in the fixed box 4. The upward movement of the auxiliary plate 43 pushes the piston plate 45 upward through the spring; and when the output end of the driving cylinder 11 contracts and resets, the hopper 1 deflects and resets. During this process, the slider 7 moves and resets in the installation groove, thereby causing the first pull rope 46 to become relaxed, so that the auxiliary plate 43 can move and reset.

[0034] See also Figure 4 , in order to make the piston plate 45 move upward to deliver the driving liquid to the telescopic tube 31 to move the scraper rod 3 only after the hopper 1 is deflected to the maximum angle, so as to avoid the problem that when the hopper 1 is not deflected to the maximum discharge angle, the scraper rod 3 moves in the direction of the hopper 1 to discharge, and the material on the inner wall of the hopper 1 cannot be effectively cleaned, preferably, the inner wall of the fixed box 4 is elastically connected to the limit plate 44 through a spring, and the limit plate 44 is set in the middle position of the fixed box 4, and the center of the limit plate 44 corresponds to the center of the protrusion, and the limit plate 44 is fixed at both ends close to the piston plate 45 There is a wedge plate, which is sealed and slidable with the side wall of the fixed box 4, and the wedge plate can slide into the fixed box 4. It should be noted that: the ends of the two sets of wedge plates that are relatively far away are provided with opposite inclined surfaces, that is, the inclined surface on the wedge plate at the top end of one side of the limiting plate 44 faces the telescopic tube 31, and the inclined surface on the wedge plate at the bottom end of one side of the limiting plate 44 faces the auxiliary plate 43, and the interval between the wedge plate at the top end of one side of the limiting plate 44 and the protrusion is adapted to the height of the piston plate 45; in actual use, the limiting plate 44 allows the two sets of wedge plates to extend into the fixed box 4 under the action of the corresponding spring, and the limiting plate 44 The wedge plate at the upper end of the plate 44 slides and fits with the top of the piston plate 45 to limit the position of the piston plate 45. At this time, the auxiliary plate 43 is at the bottom position in the fixed box 4. Then, when the driving cylinder 11 is started to drive the hopper 1 to deflect and unload, the slider 7 moves toward the fixed box 4, and the auxiliary plate 43 is pulled by the first pull rope 46 to move toward the piston plate 45 in the fixed box 4. At this time, since the piston plate 45 is limited, the spring between the auxiliary plate 43 and the piston plate 45 will be forced to shrink. When the hopper 1 is deflected to the maximum angle, the slider 7 pulls the auxiliary plate 43 through the first pull rope 46. 3 moves to the position of the limit plate 44 in the fixing box 4, so that the auxiliary plate 43 slides with the wedge block at the bottom end of the limit plate 44, so that the wedge block pushes the limit plate 44 to move away from the piston plate 45, and then the wedge block corresponding to the piston plate 45 moves and separates from the piston plate 45, and then the piston plate 45 moves upward under the action of the spring between the auxiliary plate 43 and the auxiliary plate 43 to squeeze the driving liquid in the liquid storage chamber 41 into the telescopic tube 31, so that the telescopic tube 31 expands and stretches, pushing the scraper rod 3 to move in the direction of discharging the hopper 1, and cleaning the inner wall of the scraper rod 3.

[0035] See also Figure 3 , Figure 8In order to achieve effective automatic reset after the piston plate 45 moves upward, preferably, a second pull rope 47 is fixedly provided at the bottom fixed center of the piston plate 45, and the end of the second pull rope 47 away from the piston plate 45 slides through the auxiliary plate 43, the side wall of the fixing box 4 and the end of the slider 7 close to the fixing box 4 is fixedly connected. In actual use, when the slider 7 slides in the direction of the fixing box 4 in the installation groove, the second pull rope 47 will be loose because the piston plate 45 is limited. When the slider 7 moves to the end of the installation groove close to the fixing box 4, the slider 7 moves the auxiliary plate 43 upward through the action of the first pull rope 46 and cooperates with the corresponding wedge block, so that the limit of the piston plate 45 is released. The rear piston plate 45 moves upward to move the scraper rod 3 by squeezing the driving liquid, and when the slider 7 moves and resets in the installation groove under the action of the contraction and reset of the output end of the driving cylinder 11, the slider 7 moves by pulling the second pull rope 47 to move the piston plate 45 downward and reset, thereby avoiding the problem that the piston plate 45 and the auxiliary plate 43 cannot be reset by their own gravity without the action of external force, and the movement and reset of the piston plate 45 causes the driving liquid in the telescopic tube 31 to be transported into the liquid storage chamber 41, thereby causing the scraper rod 3 to move and reset to a state where the inner end of the hopper 1 is in contact, thereby achieving an operation without manual reset, and avoiding the problem that the scraper rod 3 cannot be cleaned again due to the failure to move and reset.

[0036] See also Figure 1-Figure 10 Preferably, a vibration component 6 is provided on the side wall of the hopper 1 at one end away from the fixed box 4, and the vibration component 6 is transmission-connected to the connecting plate. Through the setting of the vibration component 6, when the scraper rod 3 moves in the direction of unloading the hopper 1, the movement of the connecting plate will also drive the vibration component 6 to reciprocately knock relative to the side wall of the hopper 1, so that the hopper 1 vibrates, accelerates the material scraped off by the scraper rod 3, and quickly completes the unloading work from the hopper 1.

[0037] See also Figure 7-Figure 10Preferably, the vibration assembly 6 includes two groups of striking blocks 61; a square plate 62 is fixedly arranged between the two groups of striking blocks 61, and the square plate 62 is arranged at the end of the striking block 61 away from the hopper 1. A positioning rod 63 is slidably connected to the center of the square plate 62, and the end of the positioning rod 63 close to the hopper 1 is fixedly connected to the hopper 1, and a spring is arranged between the square plate 62 and the hopper 1, and the spring is sleeved on the periphery of the positioning rod 63. In actual use, in the initial state, the striking block 61 is in contact with the side wall of the hopper 1, and the spring between the square plate 62 and the hopper 1 is in a normal state. When the scraping rod 3 When moving in the direction of discharging material into the hopper 1, the scraper rod 3 acts on the square plate 62 to reciprocate on the positioning rod 63, and the movement of the square plate 62 drives the striking block 61 to reciprocate relative to the side wall of the hopper 1. When the striking block 61 moves away from the hopper 1 and then moves and strikes relative to the hopper 1 under the action of the spring, the side wall of the hopper 1 will vibrate, and the material on the side wall of the hopper 1 where material is discharged will be accelerated by the vibration and fall downward, thus avoiding the accumulation of material on the side wall of the hopper 1 where material is discharged. When the hopper 1 is deflected and reset, the material on it returns to the hopper 1 again.

[0038] Further, preferably, a matching plate 64 is fixedly connected to the center of both sides of the square plate 62, and a semicircular block 65 is slidably fitted on one end of the matching plate 64 away from the square plate 62, and the semicircular block 65 is fixedly connected to the side wall of the hopper 1, and a rotating shaft 66 is rotatably connected to the side of the semicircular block 65 away from the square plate 62, and a cam 67 is fixedly connected to the outer periphery of the rotating shaft 66 near the semicircular block 65. In actual use, a groove that is slidably fitted with the matching plate 64 is provided at the end of the semicircular block 65 away from the hopper 1, and an end of the matching plate 64 away from the square plate 62 protrudes from the side wall of the semicircular block 65 and slidably fits with the cam 67. In the initial state, the matching plate 64 is fitted with the groove, and the cam 67 is away from the rotating shaft. One end of 66 faces the side wall of the hopper 1. When the shaft 66 rotates, the shaft 66 drives the cam 67 to rotate. The rotation of the cam 67 will slide and cooperate with the side wall of the protruding semicircular block 65 of the matching plate 64, thereby pushing the matching plate 64 to move away from the hopper 1. Then, when the cam 67 is separated from the matching plate 64, the matching plate 64 will quickly move toward the hopper 1 and reset under the action of the spring between the square plate 62 and the hopper 1, thereby achieving the effect of moving the striking block 61 away from the hopper 1 and then quickly moving toward the hopper 1, thereby achieving the striking block 61 hitting the hopper 1, causing the side wall of the hopper 1 to vibrate, thereby facilitating the unloading work of the hopper 1.

[0039] Furthermore, preferably, one end of the rotating shaft 66 away from the cam 67 is fixedly connected to a wire roller, a transmission box 68 is provided on the outer periphery of the wire roller, the transmission box 68 is fixedly connected to the side wall of the hopper 1, the rotating shaft 66 is rotatably connected to the transmission box 68, a third pull rope 9 and a fourth pull rope 10 are wound on the wire roller, the third pull rope 9 and the fourth pull rope 10 extend into the guide groove 8 at one end away from the wire roller through the transmission box 68 and the side wall of the hopper 1, the third pull rope 9 is fixedly connected to the side of the connecting plate away from the fixed box 4 at one end away from the transmission box 68, the fourth pull rope 10 is fixedly connected to the bottom of the connecting plate at one end away from the transmission box 68, and a second round rod is provided at the bottom of the guide groove 8 close to the telescopic tube 31, and the fourth pull rope 10 is fixedly connected to the bottom of the connecting plate at one end away from the transmission box 68. It should be noted that: the third pull rope 9 It is arranged in the opposite direction to the fourth pull rope 10 spreading on the line roller. In actual use, in the initial state, the connecting plate is in the guide groove 8 at one end close to the telescopic tube 31, the matching plate 64 is adapted to the groove, and the end of the cam 67 away from the rotating shaft 66 is toward the side wall of the hopper 1; when the hopper 1 is deflected to the maximum angle for unloading, the scraper rod 3 and the connecting plate are moved in the direction of unloading of the hopper 1 through the action of the driving assembly. At this time, the movement of the connecting plate will cause the third pull rope 9 to become loose, and the fourth pull rope 10 will spread out from the line roller and allow the line roller to rotate. The rotation of the line roller will then wind the third pull rope 9, and the rotation of the line roller will drive the rotating shaft 66 to rotate. The rotation of the rotating shaft 66 will cause the cam 67 to rotate. The rotation of the cam 67 cooperates with the matching plate 64 to realize the reciprocating knocking of the striking block 61 relative to the hopper 1, thereby achieving the effect of rapid unloading of the hopper 1.

[0040] See also Figure 1-Figure 3 Preferably, in order to prevent the material from falling into the guide groove 8 when the material is loaded into the hopper 1, preferably, the scraper rod 3 is fixedly connected to a telescopic plate 5 on one side of the top away from the fixed box 4, and the bottom of one end of the telescopic plate 5 away from the scraper rod 3 is fixedly connected to the top side wall of the hopper 1, and two groups of telescopic plates 5 are symmetrically arranged along the center of the scraper rod 3. The width of the telescopic plate 5 is larger than the top size of the guide groove 8, and the telescopic plate 5 can be extended and retracted according to the movement of the scraper rod 3, so that when the hopper 1 is loaded with materials, the telescopic plate 5 is located at one end of the hopper 1 close to the fixed box 4, and the top opening of the guide groove 8 is blocked, thereby avoiding the problem that the scraper rod 3 cannot be effectively moved on the hopper 1 due to the material falling into the guide groove 8 during loading.
