Description

Technical Field

[0001] This invention relates to the field of screw conveyor technology, and more specifically to a freely steerable hinged screw conveyor. Background Technology

[0002] A screw conveyor, also known as a screw conveyor, consists of a conveying bin and a motor at one end. The conveying bin contains a screw shaft connected to the motor. Its working principle is that the motor drives the screw shaft to rotate. When the screw shaft rotates, the screw blades rotate synchronously. The rotating screw blades push the material to the designated location. Depending on the material being conveyed, screw shafts with different blade shapes can be configured.

[0003] Traditional screw conveyors are bulky, making angle adjustment during installation extremely difficult and hindering movement. They cannot be repositioned to meet specific operational needs. To address these issues, Chinese patent CN214297909U, entitled "A Screw Conveyor for Easy Movement," discloses a novel screw conveyor. This new type comprises a support frame, a feed hopper, a first moving wheel, a conveying cylinder, support rods, support columns, and a second moving wheel. The feed hopper is located at the top of the support frame, the first moving wheel at the bottom, the conveying cylinder at the bottom, the support rods on both sides, the support column at the bottom, and the second moving wheel at the top. At the bottom of the support frame, a folded flexible hose is provided at the bottom of the feed hopper. A connector is provided on one side of the feed hopper. The conveying cylinder includes a conveying trough and a discharge port. The conveying trough is located inside the conveying cylinder. The folded flexible hose is connected to the conveying trough pipe. The connector is connected to the conveying cylinder shaft. The support rod has a telescopic groove inside. A hydraulic telescopic rod is provided inside the telescopic groove. An adjusting rod is provided at the bottom of the hydraulic telescopic rod. In use, the entire conveyor is moved to the required working location by the first and second moving wheels to achieve the effect of easy movement. Then, the support rod is rotated for support. The height of the discharge port of the conveying cylinder is adjusted by the hydraulic telescopic rod and the adjusting rod. During adjustment, the conveying cylinder is rotated through the connector to achieve the effect of easy support and adjustment of the discharge height.

[0004] However, the aforementioned hinge structure cannot accurately calculate the specific angle to be adjusted. The angle is determined solely by the operator's visual observation and experience, making it highly subjective. This means the hinge cannot maintain the optimal angle after adjustment. Especially when used repeatedly in several scenarios, the adjustment angle must be determined through repeated observation and comparison each time it is installed, making the angle adjustment process very troublesome, time-consuming, and labor-intensive. This seriously affects the efficiency of the hinge installation and subsequent operations. Therefore, there is an urgent need to invent a hinge that can solve the above problems. Summary of the Invention

[0005] In view of the above situation, in order to overcome the problem that the movable and angle-adjustable hinges in the prior art cannot accurately calculate the specific adjustment angle, resulting in highly subjective angle adjustment, which makes the angle adjustment process time-consuming and laborious, and seriously affects the efficiency of hinge installation and subsequent operations, the purpose of this invention is to provide a hinge that can achieve precise angle adjustment of the hinge while ensuring that the hinge is movable and angle-adjustable, ensuring that the adjustment process is easy and labor-saving, and significantly improving the efficiency of installation and subsequent operations.

[0006] To achieve the above objectives, the technical solution of the present invention is:

[0007] A freely steerable articulated auger includes a support frame and an auger body mounted on the support frame. The support frame includes a base with casters. The base has a first hinge point and a second hinge point. The auger body has a third hinge point and a fourth hinge point. The first hinge point of the base is hinged to the third hinge point of the auger body. The second hinge point of the base is hinged to the fourth hinge point of the auger body via a lifting platform. The distance from the first hinge point to the fourth hinge point is equal to the distance from the second hinge point to the fourth hinge point. The lifting platform has a fifth hinge point. A hydraulic cylinder is also mounted on the base. The piston rod of the hydraulic cylinder is hinged to the fifth hinge point of the lifting platform. A marking plate with angle markings is mounted on the piston rod of the hydraulic cylinder. The lifting platform is located on one side of the marking plate.

[0008] Preferably, the labeling plate includes an outer plate and an inner plate. The outer plate is semi-circular, and the angle scale is set on the outer plate. One end of the inner plate is connected to the middle of the outer plate, and the other end is fixed to the piston rod of the hydraulic cylinder and is opposite to the fifth hinge point of the lifting platform. The lifting platform is provided with directional marks opposite to the angle scale.

[0009] Preferably, the base is provided with a slide rail arranged along its length, and the piston rod of the hydraulic cylinder is provided with a slider on its outer wall, the slider being slidably connected in the slide rail.

[0010] Preferably, the piston rod of the hydraulic cylinder is provided with a positioning groove, and the piston rod is hinged to the fifth hinge point of the lifting platform through the inner wall of the positioning groove.

[0011] Preferably, a protective cover is detachably connected to the base, and the hydraulic cylinder is fixedly inserted into the protective cover.

[0012] Preferably, the protective cover has a slot in which the cylinder body of the hydraulic cylinder is installed, and the outer periphery of the protective cover has a positioning flange, which is threadedly connected and fixed to the base.

[0013] Preferably, the base is hinged with a number of corresponding latches equal to the number of casters. The latches are U-shaped and their two ends are hinged to the base. The caster seat is provided with a slot for receiving the portion between the two ends of the latches, and the slot is connected to the interior of the caster seat.

[0014] Preferably, the base has a guide groove opposite to the latch, and a pusher is threaded into the guide groove. One end of the pusher passes through the guide groove and abuts against the latch. A spring is also connected between the latch and the base, so that the latch can move in a position without disengaging from the pusher.

[0015] Preferably, the jacking component includes a screw section and a pressure head, the screw section being threadedly connected to the guide groove, and the pressure head abutting against the portion between the two ends of the locking buckle.

[0016] Preferably, the pressure head has a receiving groove, one end of the screw is inserted into the receiving groove, the inner wall of the receiving groove has an annular steering groove, and a steering block is formed on the screw that is inserted into the steering groove.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] (1) The lower end of the support frame base is equipped with casters. The casters allow the support frame and the hinge body to be adjusted in any position, solving the problem that traditional hinges are inconvenient to move due to their large size.

[0019] (2) When the lifting platform rotates around the hinge position with the base, it also rotates around the hinge position with the hinge auger body. The hinge auger body rotates synchronously with the rotation of the lifting platform around the hinge position with the base, thereby realizing the angle adjustment of the hinge auger body driven by the rotation of the lifting platform.

[0020] (3) The angle between the lifting platform and the base can be obtained by reading the angle scale at the position that coincides with the lifting platform. The angle information read is the angle between the auger body and the base. This allows the operator to intuitively and accurately obtain the angle of rotation when adjusting the angle of the auger body. According to the actual situation of the work site, the adjustment error can be reduced, and the auger can maintain the best angle after adjustment. Especially when it is used in several scenarios, it is only necessary to record the angle of the auger body when it is first installed. In subsequent installations, the auger body can be rotated to the same angle as the angle data recorded at the first time. There is no need for the operator to repeatedly observe and compare to determine the adjustment angle of the auger, which greatly simplifies the difficulty of angle adjustment and greatly improves the efficiency of the installation of the auger body and subsequent operations.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] In the description of this invention, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this invention is usually placed in when in use. They are only for the purpose of simplifying the description, and do not indicate or imply that the orientation is a specific orientation or specific orientation structure and operation, and therefore should not be construed as a limitation of this invention.

[0031] like Figure 1 and Figure 4As shown, a freely steerable articulated auger includes a support frame and an auger body 1 mounted on the support frame. The auger body 1 includes a conveyor compartment identical to existing augers, a motor located outside the conveyor compartment, and a spiral shaft located inside the conveyor compartment. The spiral shaft is connected to the motor and drives rotation. Specifically, the support frame includes a base 2, and the auger body 1 is mounted on the base 2. The lower end of the base 2 is equipped with casters 3. The casters 3 allow the support frame and the auger body 1 to be adjusted in any position, solving the problem of traditional augers being inconvenient to move due to their large size. The base 2 has a first hinge point and a second hinge point, and the auger body 1 has a third hinge point and a fourth hinge point. The third hinge point is close to the end of the auger body 1, and the fourth hinge point is a certain distance away from the third hinge point. The first hinge point of the base 2 is hinged to the third hinge point of the auger body 1, allowing the auger body 1 to rotate around the base. The second hinge point of the base 2 is hinged to the fourth hinge point of the auger body 1 via the lifting platform 4. The lifting platform 4 can rotate around the hinge points with the base 2 and the auger body 1. The base 2, the auger body 1, and the lifting platform 4 together form a linkage mechanism. When the lifting platform 4 rotates around its hinge point with the base 2, it simultaneously rotates around its hinge point with the auger body 1. The auger body 1 rotates synchronously around its hinge point with the base 2 as the lifting platform 4 rotates, thereby realizing the angle adjustment of the auger body 1 driven by the rotation of the lifting platform 4. In this invention, the distance from the first hinge point to the fourth hinge point is equal to the distance from the second hinge point to the fourth hinge point, thus forming an isosceles triangle between the base 2, the auger body 1, and the lifting platform 4. When the lifting platform 4 rotates around its hinge point with the base 2, the included angle between it and the base 2 changes continuously. At this time, the included angle between the auger body 1 and the base 2 changes synchronously by the same angle. It also has a fifth hinge point, and a hydraulic cylinder 5 is also provided on the base 2. The piston rod 501 of the hydraulic cylinder 5 is hinged to the fifth hinge point of the lifting platform 4. When the lifting platform 4 rotates, it rotates synchronously around the hinge position with the piston rod 501 of the hydraulic cylinder 5. In this invention, the hydraulic cylinder 5 is used as the power source. When its piston rod 501 pushes out or retracts, it can drive the lifting platform 4 to rotate. The hydraulic oil circuit connects the rod chamber and / or rodless chamber of the hydraulic cylinder 5 to form a hydraulic circuit. That is, the hydraulic cylinder 5 can be oiled in any of the three oil inlet methods: rodless chamber oil inlet, rod chamber oil inlet, and differential connection oil inlet. Since there is no need to manually push the lifting platform 4 to rotate, the angle adjustment of the hinge body 1 can be carried out quickly, thereby improving the efficiency of its installation and subsequent operations. In addition, a marking plate 6 is provided on the piston rod 501 of the hydraulic cylinder 5. The marking plate 6 is marked with angle scale. The lifting platform 4 is located on one side of the marking plate 6. When the lifting platform 4 rotates, the angle between the lifting platform 4 and the base 2 can be obtained by reading the angle scale at the position that coincides with the lifting platform 4. Since the angle between the hinge auger body 1 and the base 2 remains consistent with the angle between the lifting platform 4 and the base 2, the angle information read is the angle between the hinge auger body 1 and the base 2.Based on the above settings, operators can intuitively and accurately obtain the rotation angle when adjusting the angle of the auger body 1. This reduces adjustment errors based on the actual conditions of the work site, ensuring the adjusted auger maintains the optimal angle. Especially when used repeatedly in several scenarios, it is only necessary to record the angle of the auger body 1 during the initial installation. Subsequent installations simply require rotating the auger body 1 to the same angle as the initial recorded value. This eliminates the need for operators to repeatedly observe and compare to determine the adjustment angle, greatly simplifying angle adjustment and significantly improving the efficiency of auger body 1 installation and subsequent operations.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, the label plate 6 includes an outer plate 601 and an inner plate 602. The outer plate 601 is semi-circular in shape, and angle scales are set on the outer plate 601. One end of the inner plate 602 is connected to the middle of the outer plate 601, and its other end is fixed to the piston rod 501 of the hydraulic cylinder 5 and is opposite to the fifth hinge point of the lifting platform 4, so that the outer plate 601 is centered on the hinge position between the lifting platform 4 and the piston rod 501 of the hydraulic cylinder 5. Since the outer plate 601 is semi-circular, the operator can clearly observe the angle change of the lifting platform 4 inside the outer plate 601 when the lifting platform 4 rotates. In addition, the lifting platform 4 is provided with a pointing mark 401 opposite to the angle scale. The pointing mark 401 points to different angle scales when the lifting platform 4 rotates, thereby ensuring that the operator can intuitively and more accurately observe the angle of rotation of the lifting platform 4.

[0033] like Figure 1 and Figure 3 As shown, the base 2 is provided with a slide 201 arranged along its length direction, and the piston rod 501 of the hydraulic cylinder 5 is provided with a slider 501a on its outer wall. The slider 501a is slidably connected in the slide 201. Through the cooperation of the slide 201 and the slider 501a, the piston rod 501 of the hydraulic cylinder 5 can always keep sliding in a straight line direction.

[0034] like Figure 1 and Figure 3 As shown, a positioning groove 501b is provided on the piston rod 501 of the hydraulic cylinder 5. The positioning groove 501b makes the piston rod 501 of the hydraulic cylinder 5 concave. The piston rod 501 is hinged to the fifth hinge point of the lifting platform 4 through the inner wall of its positioning groove 501b. Based on the above configuration, the rotation direction of the lifting platform 4 is limited by the inner wall of the positioning groove 501b on the piston rod 501, so as to prevent it from deflecting in the horizontal direction during rotation and ensure that the operator can accurately read the rotation angle data through its rotation.

[0035] like Figure 1 and Figure 4 As shown, a protective cover 7 is detachably connected to the base 2, and the hydraulic cylinder 5 is inserted and fixed in the protective cover 7. In this invention, there is at least one protective cover 7, and there is no particular limitation on its number. The hydraulic cylinder 5 is limited by the inner wall of the protective cover 7 to prevent it from shifting during the angle adjustment process of the hinge body 1. The detachable protective cover 7 makes it easy to replace the hydraulic cylinder 5 when it is damaged, so as to avoid affecting the angle adjustment function of the hinge of this invention.

[0036] like Figure 1 and Figure 4 As shown, a slot 701 is provided in the protective cover 7, and the cylinder body 502 of the hydraulic cylinder 5 is installed in the slot 701. A positioning flange 702 is formed on the outer periphery of the protective cover 7. The positioning flange 702 is threadedly connected and fixed to the base 2. Based on the quick disassembly of the threaded connection, the protective cover 7 can be quickly disassembled, thereby improving the disassembly and assembly efficiency of the hydraulic cylinder 5.

[0037] like Figure 1 , Figure 4 and Figure 5 As shown, the base 2 is hinged with a number of corresponding latches 8 equal to the number of casters 3. The latches 8 are U-shaped and their two ends are hinged to the base 2. The caster 3 has a groove 301 on its wheel seat for receiving the portion between the two ends of the latches 8. The groove 301 is connected to the interior of the wheel seat. When the latches 8 are rotated so that the portion between its two ends is inserted into the groove 301 of the caster 3 wheel seat, it can abut against the gear in the wheel seat to restrict the rotation of the gear, thereby restricting the rotation of the caster 3 and locking it. After the support frame is moved to a suitable position on the work site, the casters 3 are locked to prevent the support frame and the auger body 1 from moving away from the selected position, thereby ensuring that the auger body 1 can be stably placed in the selected position.

[0038] like Figure 1 , Figure 4 and Figure 5 As shown, a spring is also connected between the latch 8 and the base 2. The base 2 has a guide groove 202 opposite to the latch 8. A push member 9 is threadedly connected to the guide groove 202. One end of the push member 9 passes through the guide groove 202 and abuts against the latch 8. The latch 8 can move in a position without disengaging from the push member 9. Based on the above configuration, it is convenient for the operator to rotate the push member 9 with a tool, so that the push member 9 moves relative to the base 2. When moving, it pushes the latch 8 to rotate until it engages in the slot 301 of the universal wheel 3 seat. Under the pressure of the push member 9, the latch 8 is always engaged in the slot 301, locking the universal wheel 3. When the universal wheel 3 needs to be unlocked, the push member 9 is rotated in the opposite direction. Under the action of the spring force, the latch 8 can return to its original position. During the return process, it always maintains contact with the push member 9.

[0039] like Figure 1 , Figure 4 and Figure 5 As shown, the pusher component 9 includes a screw part 901 and a pressure head 902. The screw part 901 is threadedly connected to the guide groove 202, and the pressure head 902 abuts against the portion between the two ends of the latch 8. The screw part 901 is used for the operator to control the rotation with a tool.

[0040] like Figure 6 As shown, the pressure head 902 has a receiving groove 902a, and one end of the screw part 901 is inserted into the receiving groove 902a. An annular turning groove 902b is formed on the inner wall of the receiving groove 902a. A turning block 901a is formed on the screw part 901 and inserted into the turning groove 902b. Based on the above configuration, when the screw part 901 rotates, its end drives the turning block 901a to rotate in the turning groove 902b, thereby preventing the pressure head 902 from rotating synchronously. This reduces the friction between the pressure head 902 and the locking buckle 8 when the screw part 901 rotates, ensuring that the pushing member 9 can rotate more easily. At the same time, the cooperation between the turning block 901a and the turning groove 902b can prevent the screw part 901 and the pressure head 902 from separating, ensuring that the two always remain in the docking position.

[0041] Combination Figures 1 to 6 When adjusting the position of the hinge auger of the present invention, first ensure that the latch 8 on the base 2 is separated from the wheel seat of the universal wheel 3. At this time, the universal wheel 3 can be rolled by pushing the base 2, thereby realizing the flexible adjustment of the position of the support frame and the hinge auger body 1. After moving to the appropriate position, the screw part 901 of the push member 9 is rotated by a practical tool, which drives the pressure head 902 to press down until the latch 8 is pressed into the slot 301 of the wheel seat of the universal wheel 3, locking the universal wheel 3. When the angle of the hinge auger body 1 needs to be adjusted, the piston of the hydraulic cylinder 5 pushes the lifting platform 4 to rotate. When the lifting platform 4 rotates, it drives the hinge auger body 1 to rotate, realizing the angle adjustment. When the piston rod 501 of the hydraulic cylinder 5 moves, it drives the marking plate 6 to move synchronously. When the lifting platform 4 rotates, the pointing mark 401 on the lifting platform 4 will point to different angle scales on the marking plate 6, thereby ensuring that the operator can intuitively and more accurately observe the angle of rotation of the lifting platform 4. The angle data observed by the operator is the specific rotation angle of the hinge auger body 1.

[0042] The embodiments and descriptions above are merely illustrative of the principles and preferred embodiments of the present invention. Various changes and modifications may be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
