[0002] In the production process of water-soluble fertilizers, it is usually necessary to lift the raw materials to a high place and feed them into the raw material bin from a high platform. The materials in the raw material bin are transported by their own gravity to subsequent process equipment such as mixers and agitators for processing.
[0003] In traditional production, forklifts are often used to lift fertilizer raw materials to high platforms. Forklifts are prone to danger during movement, and the amount of material lifted at a time cannot be too heavy, otherwise the forklift may overturn and hit nearby equipment or personnel, causing production accidents.

Specific implementation method:
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] In the description of the present invention, it should be noted that the terms "center", "up", "down", "front", "back", "top", "bottom", "left", "right", "vertical", "horizontal", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0024] like Figure 1As shown: a material elevator, which includes a base 1, columns 2, a lifting platform 3, and a hydraulic jacking mechanism 4; four columns 2 are vertically fixed on the base 1, in groups of two, a hydraulic jacking mechanism 4 is provided between each group of two columns 2, and a lifting platform 3 is movably provided between the four columns 2; the lifting platform 3 is driven by the hydraulic jacking mechanism 4, and can move up and down along the columns 2 to lift the raw materials required for fertilizer production.
[0025] like Figure 2 As shown, the hydraulic lifting mechanism 4 includes: a hydraulic cylinder (401), a hydraulic pump, a crossbeam (402), a first pulley (403) and a traction rope (404); the columns (2) are made of "C"-shaped channel steel, and the notches of each group of two columns (2) are arranged opposite to each other. A hydraulic cylinder (401) is arranged between the two columns (2) in each group, and a crossbeam (402) is slidably arranged between the two columns (2). The two ends of the crossbeam (402) are respectively slidably arranged in the grooves of the columns (2) on both sides. The two "C"-shaped channel steels form a set of tracks, which can keep the crossbeam 402 stably sliding in the channel steel; the bottom end of the cylinder body of the hydraulic cylinder (401) is fixedly connected to the base (1) The telescopic end of the hydraulic cylinder (401) is fixedly connected to the middle of the beam (402). The hydraulic cylinder (401) is connected to the hydraulic pump through an oil pipe and is powered by the hydraulic pump. The lifting of the hydraulic cylinder can be controlled by controlling the oil circuit valve group of the hydraulic pump. Its specific structure is the existing technology and is not described in detail. Two first pulleys (403) are symmetrically arranged on the top of the beam (402). One end of the traction rope (404) is fixed on the base (1), and the other end passes around the first pulley (403) and is fixedly connected to the lifting platform (3). When the beam 402 rises, the two first pulleys 403 are driven to rise synchronously, pulling the lifting platform 3 at the other end of the traction rope 404 to rise.
[0026] like Figure 3 , Figure 4 As shown: the lifting platform 3 includes: a load plate 301, a fence 302 and a pulley block 303. The fence 302 is provided on the two end edges of the load plate 301 adjacent to the hydraulic cylinder 401. The fence 302 is only provided on two end edges of the load plate 301, which can reserve a relatively large area of entrances and exits for loading and unloading goods, and facilitate the placement of goods on the lifting platform 3. At the same time, the fence 302 can protect the goods on the lifting platform 3 from exceeding the outer perimeter of the load plate 301, and prevent collision with other parts during the up and down movement of the lifting platform 3; a pulley block 303 is slidably provided in the grooves of the two side columns 2, and the pulley block 303 is fixedly connected to the fence 302 through a connecting piece 304.
[0027] like Figure 5As shown: it also includes an anti-tilt device 5, which includes: an anti-tilt rope 501, a second pulley 502 and a third pulley 503. The second pulley 502 is provided at the top of the column 2. The second pulley 502 is a double-wheel structure for carrying two anti-tilt ropes 501. The third pulley 503 is fixedly provided at the bottom position of the column 2 and on the base 1; two anti-tilt ropes 501 are provided between every two diagonal columns 2; one end of one of the anti-tilt ropes 501 is connected to the top of one end of the top corner of the lifting platform 3 through a basket bolt 6, and the other end is passed around the second pulley 502 at the top of the two diagonal columns 2 in sequence (that is, the anti-tilt ropes 501 are connected to the top of the two diagonal columns 2 in sequence) It passes around one of the second pulleys 502 at the top of the column 2 at the top corner position, and then passes around one of the second pulleys 502 at the top of the column 2 at the diagonal end), and the third pulley 503 on the base 1 at the bottom of the opposite column 2, and is fixedly connected to the bottom of the top corner of the diagonal end of the lifting platform 3; the top of the diagonal top corner of the lifting platform 3 is connected to the second anti-tilt rope 501 through the basket bolt 6. Similarly, the second anti-tilt rope 501 symmetrically passes around the other two pulleys of the second pulley 502 at the top of the columns 2 in the two diagonal directions in turn, and then passes around the third pulley 503 and is fixedly connected to the bottom of the top corner where the first anti-tilt rope 501 is located.
[0028] When any corner of the lifting platform 3 tilts, the position of the corner tends to move downward, and the anti-tilt rope 501 connected to it is stretched. The anti-tilt rope 501 passes through the two second pulleys 502 and the third pulley 503 on the opposite side of the diagonal direction in turn, and applies a downward pulling force to the top corner in the diagonal end direction; because when one corner tilts, the top corner of the diagonal end will tilt up, and at this time, the anti-tilt rope 501 will transmit the tension generated by the downward tilting corner to the tilted corner, and apply a downward pulling force to the tilted corner, so as to ensure that it does not tilt. At the same time, a group of two anti-tilt ropes 501 are provided in the two diagonal directions to ensure that the lifting platform 3 remains level as a whole and prevents overturning.
[0029] like Figure 6 As shown: it also includes a safety door 7, a second-layer platform 8 is provided above the base 1, and two slide rails 701 are vertically provided on the second-layer platform 8 in the exit direction on one side of the lifting platform 3, and a partition door 702 is provided between the two slide rails 701 to slide up and down, and two downwardly extending top rods 703 are fixed on the partition door 702, and the lifting platform 3 is in active contact with the bottom end of the top rod 703; when the lifting platform 3 rises to a certain height, the top rod 703 contacts the lifting platform 3, and the lifting platform 3 pushes the partition door 702 upward, thereby achieving the effect of automatic door opening, conversely when the lifting platform 3 descends, the partition door 702 descends accordingly, and after the safety door 7 is closed, it can prevent people from accidentally falling from the second-layer platform 8.
[0030] like Figure 7As shown: it also includes a first limit sensor 9, a second limit sensor 10 and a control box. The first limit sensor 9 is fixedly installed in the groove of one of the columns 2 above the crossbeam 402, and the second limit sensor 10 is installed in the groove of the same column 2 and below the crossbeam 402. The hydraulic pump is electrically connected to the control box, and the control box is electrically connected to the first limit sensor (9) and the second limit sensor (10) respectively; when the crossbeam 402 contacts the first limit sensor 9 or the second limit sensor 10, the sensor sends a signal to the control box, and the control box controls the hydraulic pump to stop, thereby controlling the lifting platform 3 to stop automatically when it is in place. The control box has a circuit for controlling the start and stop of the hydraulic pump and receiving sensor signals, which can be implemented using existing components and circuits. It is a prior art known to those skilled in the art, so it is not repeated here.
[0031] like Figure 8 As shown: it also includes a grating sensor 11, which is fixedly installed on the vertical end edges on both sides of the fence 302. The grating sensor 11 is electrically connected to the control box. When the cargo loaded on the lifting platform 3 exceeds the two boundaries of the lifting platform 3, the light of the grating sensor 11 will be blocked, thereby triggering the grating sensor 11 to send a signal to the control box. The control box controls the hydraulic pump to remain in a stopped state to prevent the cargo that exceeds the boundary of the lifting platform 3 from colliding during the lifting movement, thereby preventing the cargo from jamming the lifting platform 3 and causing a dangerous accident.
