[0029] To at least partially address one or more of the aforementioned problems and other potential issues, embodiments of this disclosure provide a material conveying device, such as... Figures 1 to 9 As shown, it includes a storage unit 1, a lifting unit 2, a transmission unit 3, and a control unit.

[0030] The storage unit 1 includes a first fixing frame 11, a storage track 12, and a discharging assembly. The first fixing frame 11 is installed at the storage station. Specifically, the first fixing frame 11 is a frame structure composed of several horizontal bars, several vertical bars, and several diagonal bars, and is fixedly connected to the ground at the storage station. The storage track 12 is fixedly connected to the first fixing frame 11. The bottom surface of the storage track 12 is inclined downwards along its inlet end to its outlet end. Preferably, the bottom surface of the storage track 12 is formed by several parallel sliding strips that extend along the extension direction of the storage track 12. More preferably, several fifth pulleys are rotatably connected in each sliding strip. The axis of the fifth pulleys is perpendicular to the extension direction of the sliding strip, and the several fifth pulleys are distributed along the extension direction of the sliding strip.

[0031] The feeding assembly is mounted on the first fixed frame 11 and is used to release one material box 5 from the storage track 12 at a time. In a preferred embodiment, the feeding assembly includes a first stop rod 13, a second stop rod 14, a first sliding sleeve 15, a second sliding sleeve 16, a connecting rod 17, a fixed rod 18, a cylinder 19, and a first spring 110. The first stop rod 13 and the second stop rod 14 are both vertically arranged and are positioned opposite each other along the extension direction of the storage track 12. The second stop rod 14 is located at the outlet end of the storage track 12, and the distance between the first stop rod 13 and the second stop rod 14 matches the size of the material box 5. The first sliding sleeve 15 and the second sliding sleeve 16 are both vertically arranged and fixedly connected to the first fixed frame 11. The first stop rod 13 and the second stop rod 14 respectively pass through the first sliding sleeve 15 and the second sliding sleeve 16, and are slidably connected to the first sliding sleeve 15 and the second sliding sleeve 16 in the vertical direction. The first end and the second end of the connecting rod 17 are respectively connected to the bottom end of the first stop rod 13 and the second stop rod 14. At the bottom end, a bearing 111 is installed on the bottom surface of the connecting rod 17 in the middle. The axial direction of the bearing 111 is perpendicular to the length direction of the connecting rod 17, and the outer ring of the bearing 111 is fixedly connected to the connecting rod 17. A fixing rod 18 is horizontally arranged and perpendicular to the connecting rod 17. The inner ring of the bearing 111 is fixedly sleeved on the fixing rod 18, and both ends of the fixing rod 18 are fixedly connected to the first fixing frame 11. When the first end of the connecting rod 17 is higher than its second end, the top end of the first stop rod 13 passes through two adjacent slide bars of the storage track 12. Between them, when the first end of the connecting rod 17 is lower than its second end, the top end of the second stop rod 14 passes through the space between two adjacent slide bars in the storage track 12; the cylinder body of the cylinder 19 is fixedly connected to the first fixed frame 11, and the piston rod of the cylinder 19 is connected to the bottom end of the first stop rod 13 for driving the first stop rod 13 to rise or fall; the first spring 110 is vertically set, the bottom end of the first spring 110 is fixedly connected to the second end of the connecting rod 17, and the top end of the first spring 110 is fixedly connected to the first fixed frame 11.

[0032] The operation of the feeding assembly is as follows: Under the action of the first spring 110, the second end of the connecting rod 17 remains higher than its first end, and the top end of the second stop rod 14 passes through the space between two adjacent sliding bars in the storage track 12, thus blocking the first material box 5 on the storage track 12; when the cylinder 19 drives the first stop rod 13 to move upward, the lever action of the connecting rod 17 causes the second stop rod 14 to move downward, the first spring 110 is stretched until the top end of the second stop rod 14 is lower than the storage track 12, and the top end of the first stop rod 13 passes through the space between the two adjacent sliding bars in the storage track 12. Between two adjacent sliders, the first material box 5 on the storage track 12 is released and the second material box 5 is blocked. When the cylinder 19 drives the first stop lever 13 to move downward, the second stop lever 14 moves upward through the lever action of the connecting rod 17 and the elastic force of the first spring 110 until the top of the first stop lever 13 is lower than the storage track 12. The top of the second stop lever 14 passes through the two adjacent sliders in the storage track 12, so that the original second material box 5 on the storage track 12 is released and slides along the storage track 12 until it is blocked at the position of the first material box 5.

[0033] The lifting unit 2 includes a mounting frame 21, a movable compartment 22, a drive unit, and a material-stopping assembly. The mounting frame 21 is vertically arranged, and its height is greater than the height of the second floor of the production workshop.

The infeed direction and the discharge direction of the movable compartment 22 are perpendicular, such as... Figure 4As shown, the x-direction is the feeding direction, and the y-direction is the discharging direction. The bottom surface of the moving box 22 is formed by several parallel discharging slides 221 spaced apart. The discharging slides 221 are inclined downwards towards the discharging direction of the moving box 22. Preferably, several fourth pulleys 2211 are rotatably connected in each discharging slide 221. The axial direction of the fourth pulleys 2211 is perpendicular to the extension direction of the discharging slide 221, and the several fourth pulleys 2211 are distributed along the extension direction of the discharging slide 221. Several vertically arranged and matrix-arranged mounting rods 23 are fixedly connected to the bottom end of the mounting frame 21. Several rows of mounting rods 23 correspond to the gaps formed between several adjacent discharging tracks. The top end of each mounting rod 23 is rotatably connected to a fourth... A pulley 231 is provided, with its axis perpendicular to the feeding direction of the moving box 22. The height of the first pulley 231 gradually decreases along the feeding direction of the moving box 22, and the first pulleys 231 in the same row are at the same height. The inclined surface formed by several first pulleys 231 connects to the outlet end of the storage track 12. When the moving box 22 is at its lowest position, several rows of mounting rods 23 are respectively inserted into the channels formed between several adjacent discharge tracks. Each first pulley 231 is higher than the discharge track, allowing the material box 5 to slide along the inclined surface of the storage track 12 and the inclined surface formed by several first pulleys 231 into the moving box 22. During the upward movement of the moving box 22, several discharge tracks carry the material box 5 upward. Preferably, a crash bar 222 is fixedly connected to the side of the moving box 22 opposite to its inlet.

Specifically, the drive unit is an electric hoist 28, which is fixedly connected to the top of the mounting frame 21, and the hook of the electric hoist 28 is fixedly connected to the top of the moving box 22. A material blocking assembly is mounted on the moving box 22 to block the outlet of the moving box 22 during its ascent.

Preferably, multiple sets of the third sliding sleeve 24, the sliding rod 25, and the second spring 26 are respectively provided, and the multiple sets of the third sliding sleeve 24 are distributed along the outlet of the moving box 22. The blocking rod 27 is horizontal and parallel to the surface of the first transmission slide 32 and is located directly below the inlet end of the first transmission slide 32. The two ends of the blocking rod 27 are fixedly connected to the second fixed frame 31. Preferably, two blocking rods 27 are arranged in parallel and side by side. When the moving box 22 is at its highest position, the horizontal section of the sliding rod 25 abuts against the blocking rod 27, the top end of the vertical section of the sliding rod 25 is lower than the top surface of the discharge slide 221, and the second spring 26 is in a stretched state. The operation of the material blocking assembly is as follows: Under the action of the second spring 26, the top of the vertical section of the sliding rod 25 remains higher than the top surface of the discharge slide 221, thus blocking the material boxes 5 on the multiple discharge slides 221; when the moving box 22 rises to near its highest position, the horizontal section of the sliding rod 25 overlaps with the blocking rod 27. As the moving box 22 continues to rise, under the blocking action of the blocking rod 27 on the horizontal section of the sliding rod 25, the vertical section of the sliding rod 25 moves downward, and the second spring 26 is stretched until the moving box 22 moves to its highest position, and the top of the vertical section of the sliding rod 25 moves to below the top surface of the discharge slide 221, releasing the material boxes 5 on the multiple discharge slides 221.
