Description

Technical Field

[0001] The present invention relates to a rock processing machine having a loading hopper and a processing unit arranged after the loading hopper, wherein a conveying mechanism, particularly a hopper traction belt, is provided for the loading hopper, wherein the loading hopper has a hopper sidewall, and wherein a sidewall lifting portion is provided for the hopper sidewall, the sidewall lifting portion being oscillating between a tilted working position and a tilted transport position. Background Technology

[0002] Rock processing equipment is used for various purposes. For example, it is used to crush and / or screen recycled and / or rock materials during the preparation process. The machine can be used as a mobile or stationary device. The material to be processed is filled into the loading hopper of the equipment via a loading unit. An excavator is typically used for this. The excavator places the material to be crushed or screened into a conveyor or trough, which is then assigned to the loading hopper. The material to be processed is guided along the conveying direction by the conveyor to the subsequent processing unit. The material is then processed in the subsequent processing unit, for example, by crushing or screening it.

[0003] The loading hopper acts as a buffer volume, supplying material to the rock processing machine until the excavator reloads it. Therefore, the loading hopper must provide a sufficiently large volume to both practically accommodate the material filled by the excavator bucket and provide a buffering effect. Consequently, the loading hopper is constructed to protrude wide upwards onto the machine.

[0004] Rock processing equipment is a machine with significant external dimensions. A crane transport vehicle is used to move the machine to the appropriate working position. Therefore, the machine's external dimensions must allow for transport within legal limits. It has been found that loading funnels are often problematic in this regard, especially in areas where the height of the largest structural space is limited. Therefore, it is known that the sidewalls of loading funnels are constructed in multiple parts. Thus, the sidewalls have fixed wall portions and one or more hinged, reversible wall portions.

[0005] In large machines, a large hopper widening section is located at the reloading point of the excavator. This widening section, due to its large weight, is mostly hydraulically oscillating. Along the material transport direction, a lower sidewall riser is connected to the high hopper widening section; this sidewall riser is also arranged to be tiltable. This sidewall riser is manually operated by the operator and positioned in the work area. For this, the operator must enter the transport area of ​​the loading hopper and then raise or lower the sidewall riser from this point. This operation is problematic for safety reasons. Summary of the Invention

[0006] The object of this invention is to provide a rock processing machine of the type described at the beginning, which is designed to meet the requirements of work safety.

[0007] This objective is achieved by equipping the sidewall lifting section with an operating unit featuring a lever to allow the sidewall lifting section to swing, wherein the lever is coupled to the sidewall lifting section via a transmission element. Therefore, the user can conveniently and assistedly swing the sidewall lifting section between a transport position and a working position using leverage. This eliminates the need for the user to move within the hazardous area of ​​the loading hopper. The transmission element allows the user to operate the lever from a reliable position, for example, when positioned on a workbench; the lever is coupled to the transmission element.

[0008] Once the user has moved the sidewall lifting section to the raised working position, the user can fix the position of the sidewall lifting section using an adjustable locking element. Alternatively, the user can operate from a fixed position, for example, by adjusting the locking element from the worktable to lock the sidewall lifting section in the working position. Thus, the rock processing machine according to the present invention satisfies the requirements for operational safety in a simple manner.

[0009] A preferred embodiment of the invention can be configured such that the lever is coupled or can be coupled to the transmission element via a releasable form-locking connection preferably configured as a plug-in connection, wherein the form-locking connection forms a form lock along the swing direction of the lever. The user can couple the lever to the transmission element when they wish to adjust the sidewall rise. After the user has completed this operation, the lever can be removed again and supported in a reliable storage location near the transmission element. The removable lever remains undisturbed in the area of ​​the sidewall rise and therefore poses no safety risk.

[0010] The side wall riser is configured to swing around a swing axis by means of one or more swing bearings, wherein the swing bearings are directly or indirectly fixed to the side wall riser by support sections and directly or indirectly fixed to the funnel side wall by paired support members, and the operating element is non-rotatably coupled to the support section of one of the swing bearings, thus achieving a simple and stable structure.

[0011] Particularly preferably, the funnel sidewall, the raised sidewall portion, and the raised sidewall portion can extend along the transport direction of the conveying mechanism around the swing axis, and the lever is arranged on the rear end region of the sidewall along the transport direction, so that the operator, preferably standing on the workbench, can access the lever. The rock processing machine forms a smaller width in this area than at the loading funnel. In this respect, the workbench for the operator has little or no impact on the transport width of the rock processing machine. A reliable standing position for comfortable operation is achieved via the workbench.

[0012] When the locking slider is coupled to the locking element via a connecting section, wherein the locking slider carries or is coupled to the handle, and the handle is preferably arranged in the area of ​​the lever, the locking element can be easily operated from the operator's position.

[0013] Alternatively, the locking slider can be connected to the lever in a way that prevents relative rotation. The locking element can then be adjusted using the locking slider, causing the raised sidewall to swing. This achieves a conceivable, simple construction.

[0014] As mentioned above, a workbench can be arranged in the area of ​​the loading funnel, the workbench having a platform section through which the operator can access the lever and handle of the locking slider.

[0015] The sidewall riser preferably terminates in the area of ​​the platform section, and the locking element is carried at the end of the locking slider away from the platform section. In this way, the area of ​​the sidewall riser away from the worktable can be reliably locked from the worktable. It is also convenient to additionally lock the sidewall riser from the worktable as needed, and lock the sidewall riser at the end of the sidewall riser near the worktable.

[0016] A possible variation of the invention is designed such that the raised portion of the sidewall is oscillatingly coupled to the sidewall of the funnel by means of two or more oscillating bearings, and the oscillating bearings have guide elements that form a guide for the movement of the locking slider. This achieves a space-saving and simple structure. Preferably, the oscillation axis of the oscillating bearing can also be arranged to extend through the guide elements.

[0017] The rock processing machine according to the invention can be implemented such that the transmission element is configured as an open or closed hollow shape or has an open or closed hollow shape, and the locking slider is guided in or on the hollow shape. Therefore, the hollow shape provides reliable guidance for the locking slider.

[0018] If the handle for adjusting the locking slider between the locked and unlocked states of the locking element is coupled to the locking slider, the locking slider can be easily operated. Preferably, the handle can also be guided in the guide portion of the transmission element. This ensures a defined correspondence between the handle and the transmission element. The guide portion can be formed, for example, by a hollow notch through which the handle extends. This achieves a stable and reliable operating implementation.

[0019] The locking slider is configured to have a receiving portion for a locking element that blocks the adjusting movement of the locking slider in the unlocked position when the locking slider is in the locked position. Preferably, the locking element is arranged in the operating area of ​​the lever to prevent unintentional loosening of the locking element and tipping of the sidewall riser during operation of the rock processing machine.

[0020] To reduce component and installation costs, the locking slider can be configured as a shaped section or having such a shaped section, wherein the shaped section carries the locking element at one end on its longitudinal side and is guided to the operating area of ​​the lever at the other end. For example, in the simplest manner, a solid rod-shaped, especially a round rod, can be used as the shaped section. Preferably, the locking element and the shaped section are implemented as a single piece.

[0021] In particular, it is conceivable that the shaped section of the locking slider has a curved area at its end opposite the lever, the curved area forming a connecting section and the curved area maintaining the locking element at a distance from the swing axis of the side wall riser. A lever arm is formed via this distance, through which the load of the side wall riser can be reliably unloaded in the working position. By bending the locking element from the shaped section, a robust and simple structure is obtained.

[0022] A conceivable variation of the invention is designed such that the locking slider carries an additional locking element besides the locking element itself. This additional locking element is arranged with a gap between the swing axis of the sidewall riser and the lever-facing region. This additional locking element provides additional fixation, thereby allowing, for example, the load on the sidewall riser to be unloaded via two locking elements. In the case of eliminating the locking element, the additional locking element serves as a redundant element. With two locking elements at the locking slider, in a suitable design, the two locking elements can be adjusted between their locked and unlocked positions by means of a locking movement.

[0023] Another variation of the invention is that the transmission element is part of the locking slider, wherein the lever is connected to the locking slider in a non-rotatable manner. Attached Figure Description

[0024] The invention will now be described in detail with reference to embodiments shown in the accompanying drawings. Wherein:

[0025] Figure 1 A perspective view of the rock processing equipment is shown.

[0026] Figure 2 It shows according to Figure 1 A side view of a rock processing equipment.

[0027] Figure 3 It shows Figure 1 Detailed images in the image.

[0028] Figure 4 It shows Figure 3 A 3D diagram showing the changes in details, and

[0029] Figure 5 It shows according to Figure 3 The diagram illustrates the changing operating state. Detailed Implementation

[0030] Figure 1 A rock processing machine 10 is shown, and the invention is described exemplarily based on this rock processing machine. This rock processing machine 10 is a screening machine. However, the invention is not limited to applications in screening machines. Rather, the invention can also be applied to other rock processing machines, such as rock crushers, especially jaw crushers or rotary vibratory crushers. The invention can also be applied to combined rock crushing equipment with screening devices. Therefore, the following description is only exemplarily illustrated with respect to screening equipment. The following embodiments are particularly applicable to the aforementioned rock processing equipment.

[0031] like Figure 1 As shown, the rock processing machine 10 has a frame 13, which is supported by a traveling mechanism 14, for example, configured as a chain-driven mechanism. The rock processing machine 10 also has a loading hopper 40. The rock processing machine can load the rock material to be processed via the loading hopper. A conveying mechanism is provided in the area of ​​the loading hopper 40, which is formed, for example, by a hopper traction belt 12. Instead of the hopper traction belt 12, a conveying trough with a conveying mechanism, implemented as a vibrating conveyor, is also conceivable.

[0032] Immediately following the loading hopper 40, the rock processing machine 10 has a processing unit 20. The processing unit 20 is a screening mechanism.

[0033] The following is for reference. Figure 2 The structure and function of the screening mechanism are described in detail. As shown in the schematic diagram, the processing unit 20 has a screening hood 21 immediately following the funnel traction belt 12. Rock material is conveyed to this screening hood by means of the funnel traction belt 12. The screening hood 21 has a grid screen with a predetermined screen aperture size. Rock material that cannot pass through the screening hood 21 due to its structural size is conveyed to the conveyor belt 15 and then from the conveyor belt to the waste pile. Rock material that passes through the screening hood 21 reaches the screening hood 22. The screening hood 22 also has a predetermined screen aperture size. Rock material that does not pass through the screening hood 22 is conveyed to the conveyor belt 17. The conveyor belt 17 extends laterally from the working area of ​​the processing unit 20. The screened material is piled up, such as... Figure 2 As shown. The screened material falling through the screening hood 22 reaches the conveying mechanism 23, such as an endlessly looping conveyor belt. The screened fine material is guided to the conveyor belt 16 and discharged from the machine's working area via the conveyor belt. The screened fine material also accumulates on the side of the machine. The two screening hoods 21 and 22 are driven by a vibration drive, especially an eccentric wheel drive.

[0034] The conveyor belt 15 can be moved to a lower position, thereby allowing the screening hood 21 to pass over the upper hood and material ( -Oberdeck-Material) and screening hood 22 over-range-lower hood-material ( The underdeck material is discharged via conveyor belt 15 and thus only two sieved particle sizes are separated. Therefore, only one lateral conveyor belt 16 is constructed. Therefore, the second lateral conveyor belt 17 is eliminated, or the second lateral conveyor belt is removed or introduced into a position / arrangement at the equipment where the conveyor belt is not in operation.

[0035] It is also conceivable that conveyor belts 16 and 17 can be optionally installed on one of the two sides of the machine, as compared. Figure 1 and Figure 2 It can be seen that conveyor belts 16 and 17 are arranged on the same side of the equipment.

[0036] like Figure 1 As shown, the machine has two worktables 30 facing the longitudinal sides of the machine. The worktables 30 are accessible via risers 18, such as ladders. An access platform 31 is provided immediately adjacent to the risers 18. The access platform 31 transitions into an inclined platform section 32. A reversible platform widening section 33 is connected to the stationary platform section 32. The platform widening section 33 transitions into another stationary flat section 34. The flat sections 33 and 34 have climbable access surfaces that transition into the bottom section 33.1 of the platform widening section 33.

[0037] like Figure 1 It is also evident that the worktable 30 is limited on one side by means of the boundary portion 24 of the processing unit 20. The boundary portion 24 may be configured, for example, in the form of a wall that extends along the longitudinal direction of the worktable 30 and along the longitudinal direction of the rock processing mechanism 10.

[0038] A component of the processing unit 20 is connected to the boundary portion 24. The component has a protrusion 24.5 that extends outward onto the boundary portion 24. Here, the protrusion 24.5 extends onto the bottom region 39, which extends below the protrusion 24.5. The bottom region 39 is aligned with the two platform sections 32 and 34.

[0039] exist Figure 1 In the illustrated work position, the bottom section 33.1 of the platform extension 33 is positioned on the side relative to the platform sections 32 and 34. In this way, a user moving on the worktable 30 can bypass the protrusion 24.5 in the passage between the two platform sections 32 and 34 without having to cross the protrusion.

[0040] like Figure 1As shown, the workbench 30 is defined on the side opposite to the boundary portion 24 by means of a fall arrest mechanism 35. The fall arrest mechanism 35 may have multiple sections. In this embodiment, the fall arrest mechanism has a safety section 35.1 in the area of ​​the access platform 31. In addition, a fixed railing section 35.3 is arranged spaced apart from the safety section 35.1. The railing section 35.3 is fixedly assigned to the platform section 32. An access area 35.2 is recessed from the fall arrest mechanism 35 between the safety section 35.1 and the railing section 35.3. The access platform 31 can be reached via the riser 18 through this access area 35.2.

[0041] Another railing section 35.4 of the fall arrestor is assigned to the platform section 34. An end section 35.5 is connected to this railing section 35.4. The end section spans the area between the railing section 35.4 and the boundary portion 24 of the processing unit 20.

[0042] A railing section 36 is arranged between two railing sections 35.3 and 35.4. Railing section 36 is assigned to the platform widening section 33.

[0043] like Figure 1 It can be seen that platform section 34 terminates in the area of ​​the loading hopper 40.

[0044] The charging hopper 40 has a rear wall 41, on which a side wall 42 is connected laterally. Here, the side wall 42 extends along the conveying direction of the hopper traction belt 12. The rear wall 41 and the side wall 42 are configured as stationary components. In the region of the rear wall 41, a swivelly widened portion 43 is coupled to the side wall 42, extending the surface of the side wall 42 facing the internal space of the hopper. The widened portion 43 can be remotely operated via a hydraulic adjustment mechanism. Figure 1 Adjustment is made between the shown working position and the tilted transport position. In the tilted transport position, the funnel widening 43 rests against the frame 13 on its side.

[0045] Along the transport direction of the funnel traction belt 12, after the funnel widening section 43, side wall raising sections 44 are provided on the two funnel side walls 42. The side wall raising sections 44 may also be located on... Figure 1 The diagram shows a swing between the vertical working position and the tilted transport position.

[0046] from Figures 3 to 5 The shape of the raised section 44 on the side wall is clearly visible. For example... Figure 3 As shown, the raised sidewall 44 is formed by a cutting plate, which extends the funnel sidewall 42 upward in the vertical working position. The raised sidewall 44 has a bent edge 44.5 at its end facing the widened funnel 43. Figure 3As can be seen, the curved edge points outward, so that the inner side 44.7 of the sidewall rise 44 transitions into the surface of the funnel widening 43 with virtually no interruption.

[0047] On the outer side 44.6 opposite to the conveyor belt 12, the side wall rise 44 is equipped with a support section 44.2 of the swing bearing 44.1.

[0048] The support section 44.2 may be formed, for example, from a cut blank of plate shape, wherein every two support sections 44.2 are part of the oscillating bearing 44.1, as shown below. Figure 3 As shown.

[0049] Support section 44.2 carries guide element 44.3. Guide element 44.3 is implemented as a hollow cylindrical sleeve. Locking receptacles 44.4 are introduced into one or both support sections 44.2 of the oscillating bearing 44.1. In this embodiment, locking receptacles 44.4 are machined into both support sections 44.2 of the oscillating bearing 44.1, and the locking receptacles are aligned with each other.

[0050] The raised sidewall portion 44 can be hooked into the mating support 42.1 by means of the guide element 44.3. Figure 5 As shown, the mating support 42.1 is fixed on the outside, for example, welded to the funnel sidewall 42.

[0051] The mating support has a fixing section 42.2, which is secured to the funnel sidewall 42. A locking section 42.3 is provided spaced apart from the fixing section 42.2. The locking section 42.3 and the fixing section 42.2 transition into each other in a U-shape via a connecting section. Therefore, a guide element 44.3 can be inserted from above into the area between the fixing section 42.2 and the locking section 42.3, as shown. Figure 5 As shown. A connection locking mechanism 42.4 is arranged above the guide element 44.3. This connection locking mechanism prevents the guide element 44.3 from... Figure 5 The mounting position shown is disengaged. The guide elements 44.3 of the swing bearing 44.1 are aligned with each other and form a swing axis, and the side wall rise 44 can swing about the swing axis.

[0052] like Figure 3 As shown, the transmission element 52 is non-rotatably coupled to the oscillating bearing 44.1 near the platform section 34. For example, the transmission element 52 is non-rotatably connected to the support section 44.2, for example, by welding. The transmission element 52 has a receiving portion, especially a plug-in receiving portion. A lever 51 with a protrusion, especially a plug-in protrusion, can be inserted into the plug-in receiving portion.

[0053] As lever 51 moves out of platform section 34, force is introduced via transmission element 52 to support section 44.2 of sidewall riser 44. With the introduced force, sidewall riser 44 can move within swing bearing 44.1. Figure 3 The work location shown and Figure 5 The transportation locations shown oscillate between each other.

[0054] Figure 3 It is also shown that the operating unit 50, which includes the lever 51 and the transmission element 52, also has a locking slider 62. The locking slider 62 extends from the end of the side wall riser 44 assigned to the platform section 34 in the direction of the swing axis of the side wall riser 44 and in the direction of the end of the side wall riser 44 away from the platform section 34.

[0055] The locking slider 62 has a shaped section, which is preferably constructed of a solid round rod. The locking slider 62 moves via the guide element 44.3. In the region of the rear swing bearing 44.1, the locking slider 62 carries the locking element 60.

[0056] As shown in the accompanying drawings, the locking element 60 can be configured as a bolt, which is bent in one piece from the locking slider 62. In this embodiment, the locking element 60 is bent 180° relative to the locking slider 62. Other angles are also conceivable. The transition region between the locking slider 62 and the locking element 60 is formed by an arc-shaped connecting section 61. The connecting section 61 is also part of the locking slider 62.

[0057] At the end region opposite to the locking element 60, the locking slider 62 is inserted into the hollow transmission element 52. The transmission element 52 has a side notch forming a guide portion 53. A handle 63 connected to the locking slider 62 extends through the guide portion 53. Also... Figure 1 As shown, the locking slider 62 extends from the transmission element 52 at its free end and has a stop 65 thereon.

[0058] exist Figure 3 The image shows the locked position of the locking slider 62. In this position, the locking slider is pulled into its locked position by means of the handle 63, wherein the handle 63 stops at the end of the slit-shaped guide portion 53. A locking element 64, for example in the form of a cotter pin, is used to secure this position. The locking slider 62 has a receiving portion for the locking element 64. The locking element 64 is form-fitted against the transmission element 52 in the direction of movement of the locking slider 62.

[0059] In the locked position shown, the locking element 60 is inserted into the two locking receptacles 44 of the support section 442 of the rear swing bearing 44.1. A support gap is obtained by spacing the locking element 60 from the swing axis of the sidewall riser 44. The support gap prevents the sidewall riser 44 from unintentionally tipping off from the working position shown.

[0060] If the user wishes to fold down the side wall lift 44, they can ascend to platform section 34. The lever 51 and handle 63 of the operating unit 50 are located nearby. The user first releases and removes the safety element 54. The user can hold the side wall lift 44 via the lever 51. Then, the user uses the handle 63 to push the locking slider 62 backward along the swing axis of the side wall lift 44. Here, the locking element 60 disengages from the swing bearing 44.1. The user can then use the lever 51 to slowly swing the side wall lift into the folded transport position. After the side wall lift 44 reaches this position, the user can pull the lever 51 down from the transmission element 52 and place the lever in a safe position.

[0061] In the opposite direction, from Figure 5 The transportation location shown is adjusted to Figure 3 The installation location is shown.

[0062] like Figure 4 As shown, a retainer 44.9 is provided in the region of the rear swing bearing 44.1. When the locking slider is in its unlocked position, the retainer 44.9 accommodates the free end of the locking element 60. At the same time, the stop 65 abuts against the transmission element 52, thereby preventing the locking slider from moving further in the unlocking direction. This measure ensures that the locking element 60 is always correctly positioned and assigned to the swing bearing 44.1.

[0063] like Figure 3 and Figure 4 As can be seen, another safety element 44.8 can also be used to secure the mounting position of the side wall riser 44. This other safety element can be mounted on the swing bearing 44.1, which is assigned to the platform section 34 and located near the user. The safety element 44.8 can be constructed as a bolt. The bolt is inserted and secured through the aligned locking receptacles 44.4 of the support section 44.2 of the swing bearing 44.1.
