Description

Technical Field

[0001] This utility model belongs to the technical field of crusher equipment, and in particular relates to a crusher feeding hopper device. Background Technology

[0002] Existing mobile crusher feed hoppers consist of two side plates and a rear plate. Due to height limitations during transport, mobile crushers often employ a foldable and tilting mechanism for the feed hopper. This allows the side and rear plates to be folded to reduce height during transport. However, during operation, the side and rear plates must be raised sequentially to designated positions, and then manually inserted pins to lock them together. This locking process is achieved by manually inserting and removing the pins. During relocation, the pins must be manually removed before lowering the rear and side plates. Locking and tilting require working at height and manually inserting and removing pins, which is time-consuming, cumbersome, inefficient, and poses safety hazards. Existing improvements (such as adding auxiliary support structures) do not address the issues of automated locking and folding height optimization. Therefore, a solution that combines automatic locking with height optimization is urgently needed. Utility Model Content

The lower ends of each transverse side plate 30 are rotatably connected to the first support seats 32. Each fixed base 1 has a locking part for restricting the rotation of the transverse side plate 30. Locking mechanisms that rotatably extend to the locking parts of each first support seat 32 are provided on the outer walls of both ends of each transverse side plate 30. Component 33, below the rear side plate 31 and along the rear edge of the U-shaped opening 10, has at least two second support seats 34 fixedly mounted on the fixed base 1. The lower sides of both ends of the rear side plate 31 are rotatably mounted on the second support seats 34. In this invention, the feeder body 2 is a plate feeder. A first drive assembly 35 is mounted on the fixed base 1 between the two first support seats 300 on each side of each U-shaped opening 10. The drive output end of the first drive assembly 35 is rotatably connected to the upper outer wall of the transverse side plate 30, and the fixed end of the first drive assembly 35 is rotatably connected to the fixed base 1. On the outer side wall, a second drive assembly 36 is provided on the fixed base 1 between the two second support seats 34; the first drive assembly 35 and the second drive assembly 36 are hydraulic cylinders or electric cylinders; the locking mechanism of the locking assembly 33 on the transverse side plate 30 is as follows: when the first drive assembly 35 drives the transverse side plate 30 to rise to the working angle, the locking assembly 33 rotates and extends towards the locking part of each first support seat 32 to form a self-lock; the unlocking mechanism of the locking assembly 33 on the transverse side plate 30 is as follows: the locking assembly 33 rotates and moves out of the locking part of each first support seat 32, and the locking assembly 33 disengages from the locking part of the first support seat 32 to achieve unlocking.

[0037] In this utility model, such as Figure 2 , Figure 3 and Figure 4As shown, there are four elastic support components 11. The four corner positions of the feeder body 2 are respectively mounted on the fixed base 1 via the elastic support components 11. A vibrator 12 is installed on the bottom of the feeder body 2 located at the rear end of the U-shaped opening 10. Each elastic support component 11 includes a vibration support spring 110, upper bearing seats 111 on the outer walls of the four corners of the feeder body 2, and lower bearing seats 112 located below each upper bearing seat 111 and fixed to the fixed base 1. 111 is horizontally and vertically fixed to the four outer corner walls near the feeder body 2.

Under the action of vibration, the material in the feeder body 2 falls from the U-shaped opening 10 of the fixed base 1 to the conveyor belt of the next process. When the feeder body 2 is vibrating and feeding, the feeder body 2 drives the vibration support spring 110 to vibrate back and forth through the upper bearing seat 111, so that the limiting sliding hole of the upper vibration support plate 113 slides in the limiting sliding hole 116 on the vibration limiting plate 115 through the sliding pin (not shown), to prevent the vibration displacement of the feeder body 2 from being too large.

[0038] In this utility model, such as Figure 1 , Figure 5 , Figure 6 , Figure 7A pair of parallel locking limiting plates 320 are arranged on both sides of the first support base 32 in a vertical direction. A flip pin 321 is horizontally arranged between the top ends of the pair of locking limiting plates 320.

The flip pin 321 is sleeved in the flip support sleeve 323a. The lower end of the flip support rib 322 rotates along the flip pin 321 between the top ends of the pair of locking limiting plates 320 through the flip support sleeve 323a. The upper end of the locking assembly 33 is rotatably connected to a... On the outer wall of the transverse side plate 30 between the top ends of the flip support rib 322, the middle part of the locking assembly 33 is vertically slidably disposed on the outer wall of the flip support rib 322. When the middle part of the locking assembly 33 slides downward, it drives the locking parts on both sides of the lower end of the locking assembly 33 to rotate and extend toward the locking parts at the top ends of a pair of locking limit plates 320. The locking assembly 33 includes a locking drive mechanism 33a and a rotating locking mechanism 33b. The upper end of the locking drive mechanism 33a is rotatably connected to the outer wall of the transverse side plate 30 between the top ends of a pair of flip support ribs 322. The lower end of the locking drive mechanism 33a is slidably disposed on the outer wall of the flip support rib 322. The upper end of the rotating locking mechanism 33b is rotatably connected to the lower end of the locking drive mechanism 33a. The locking parts on both sides of the lower end of the rotating locking mechanism 33b rotate and extend toward the locking parts at the top ends of a pair of locking limit plates 320.

A suspension support shaft 325 is horizontally arranged between the suspension support plates 324, and the upper end of the limiting locking hydraulic cylinder 330 rotates onto the suspension support shaft 325 between the two suspension support plates 324; thereby locking the upper end of the limiting locking hydraulic cylinder 330. The suspension support shaft 325 is rotatably mounted on the suspension support plate 324. A sliding channel opening 335 extending vertically is provided in the middle of the locking guide support plate 323. The sliding pin 331 is vertically arranged on the sliding channel opening 335. A side fixing seat 336 is sleeved on the outer wall of the sliding pin 331 located on the front side of the locking guide support plate 323. The upper end of the limiting locking hydraulic cylinder 330 is rotatably arranged on the outer wall of the transverse side plate 30 between the top ends of a pair of flipping support ribs 322. The lower end of the limiting locking hydraulic cylinder 330 is connected to the outer end of the sliding pin 331. The locking guide is located above the flipping pin 321 and below the sliding channel opening 335. The constraint component block 334 is fixed to the side wall of the support plate 323. The locking and limiting ends of the first limiting wedge 332 and the second limiting wedge 333 are rotatably connected to the sliding pin 331 between the lower end of the limiting locking hydraulic cylinder 330 and the side fixing seat 336. The positioning ends of the first limiting wedge 332 and the second limiting wedge 333 are rotatably connected to both ends of the constraint component block 334. When the limiting locking hydraulic cylinder 330 pushes the sliding pin 331 downward along the sliding channel opening 335, it drives the positioning ends of the first limiting wedge 332 and the second limiting wedge 333 to rotate around the two ends of the constraint component block 334 as the positioning center. The movement causes the locking limit end of the first limiting wedge 332 and the locking limit end of the second limiting wedge 333 to rotate into the locking part at the top of the locking limit plate 320 on the corresponding side; a first locking link 337 is provided between the outer wall of the sliding pin 331 and the locking limit end of the first limiting wedge 332, and a second locking link 338 is provided between the outer wall of the sliding pin 331 and the locking limit end of the second limiting wedge 333. The upper end of the first locking link 337 is rotatably connected to the outer wall of the sliding pin 331 between the lower end of the limiting locking hydraulic cylinder 330 and the side fixed seat 336, and the lower end of the first locking link 337 is rotatably connected to the locking limit end of the second limiting wedge 333.The upper end of the second locking link 338 is rotatably connected to the outer wall of the sliding pin 331 between the upper end of the first locking link 337 and the side fixing seat 336. The lower end of the second locking link 338 is rotatably connected to the locking and limiting end of the second limiting wedge 333. The locking parts at the top of the pair of locking limiting plates 320 are respectively used to engage and limit the first limiting shoulder 3200 and the second limiting shoulder 3201 of the first limiting wedge 332 and the second limiting wedge 333. A shoulder for locking support is formed in front of the top of the two locking limiting plates 320 and near the transverse side plate 30. When the first limiting wedge 332 and the second limiting wedge 333 rotate and extend into... The two shoulders at the top of the locking and limiting plate 320 limit and lock the transverse side plate 30. An L-shaped elastic pad 3202 is respectively provided on the surface of the first limiting shoulder 3200 and the surface of the second limiting shoulder 3201. During the hopper's gravity or material descent, the pressure continuously increases, strengthening the transverse side plate 30. This causes the transverse side plate 30 to press the first limiting wedge 332 against the first limiting shoulder 3200 and the second limiting wedge 333 against the second limiting shoulder 3201. The locking assembly 33 not only stably buffers and locks the transverse side plate 30 through the shoulder locking position but also prevents rigid collisions between the wedges and the shoulder locking position.

A constraint groove 3342 for constraining the constraint block nested in the constraint base 3340 is provided on the back side wall of the constraint support block 3341. A first bolt 3343 is used to fix the constraint support block 3341 to the constraint base 3340 through the center of the constraint groove 3342. The two ends of the constraint support block 3341 are rotatably connected to the positioning ends of the first limiting wedge 332 and the second limiting wedge 333 respectively through wedge pins 3344. A first groove 332a is provided on the side of the first limiting wedge 332 located on one side of the constraint support block 3341, and a second groove 333a is provided on the side of the second limiting wedge 333 located on one side of the constraint support block 3341. The positioning end of the first groove 332a of the first limiting wedge 332 and the positioning end of the second groove 333a of the second limiting wedge 333 are respectively nested on the outer walls of both ends of the constraint support block 3341 and rotatably connected by the corresponding wedge pins 3344. The locking limiting end of the first groove 332a of the first limiting wedge 332 is sleeved on the lower end of the first locking link 337 and rotatably connected by the first pin 338a. The lower end of the first locking link 338 is rotated through the first pin 338a and connected to the first groove 332a of the first limiting wedge 332. The locking limiting end of the second groove 333a of the second limiting wedge 333 is sleeved on the lower end of the second locking link 338 and rotatably connected by the corresponding second pin 338b. The lower end of the second locking link 338 is rotatably connected through the second pin 338b and connected to the second groove 333a of the second limiting wedge 333.The back of the constraint support block 3341 is fitted onto the constraint base 3340 through the constraint groove 3342, so that a gap space can be formed between the constraint support block 3341 and the locking guide support plate 323 when the first limiting wedge block 332 and the second limiting wedge block 333 rotate. During the up-and-down sliding process of the sliding pin 331 driven by the limiting locking hydraulic cylinder 330, the first locking connecting rod 337 pushes the first limiting wedge block 332 and the second locking connecting rod 338 pushes the second limiting wedge block 333. The positioning ends of the first limiting wedge block 331 and the second limiting wedge block 333 rotate along the wedge pin 3344 on the constraint support block 3341, respectively. The groove in the first limiting wedge block and the second limiting wedge block 3343 rotate along the wedge pin 3344 on the constraint support block 3341. The grooves in the limiting wedge 333 move along the outer wall of the constraint support block 3341. The first locking link 337 and the second locking link 338 enter or leave the grooves in the first limiting wedge and the second limiting wedge 333, respectively. During the rotation of the first locking link 337 and the second locking link 338 along the first pin 338a and the second pin 338b, the first locking link 337 and the second locking link 338 have more room to move when they are close to the grooves in the first limiting wedge and the second limiting wedge 333, respectively. At the same time, the first locking link 337 and the second locking link 338 are restricted, limiting the movement of the link within the groove.

[0041] In this utility model, combined with Figures 1 to 11 The locking mechanism of the locking assembly 33 on the transverse side plate 30 is as follows: when the first drive assembly 35 drives the transverse side plate 30 to rise to the working angle, the limiting locking hydraulic cylinder 330 extends downward, pushing the sliding pin 331 to slide downward along the sliding channel opening 335 of the locking guide support plate 323. During the downward sliding process of the sliding pin 331, the first limiting wedge 332 is pushed to rotate along the constraint support block 3341 by the first locking link 337, and the second locking link 338 pushes the second limiting wedge 333 to rotate along the constraint support block 3341. In this utility model, the locking mechanism of the locking assembly 33 on the transverse side plate 30 is as follows: when the first drive assembly 35 drives the transverse side plate 30 to rise to the working angle, the limiting locking hydraulic cylinder 330 extends downward and pushes the sliding pin 331 to slide downward along the sliding channel opening 335 of the locking guide support plate 323. During the downward sliding process of the sliding pin 331, the first limiting wedge 332 is pushed to rotate along the constraint support block 3341 by the first locking link 337, and the second locking link 338 pushes the second limiting wedge 333 to rotate along the constraint support block 3341.

[0042] As shown in the figure, Figure 12 , Figure 13 and Figure 14The feeding hopper device of this utility model utilizes the gravity of the hopper or the pressure continuously increasing during the material's descent to enhance the pressure on the transverse side plate 30, causing the transverse side plate 30 to press against the locking assembly 33 to achieve a locking effect (the heavier the material, the greater the locking force). The hydraulic lifting drive of the hopper is equipped with three sets of hydraulic cylinders, which respectively control the lifting of the rear side plate and the two side plates. Specifically, the two transverse side plates 30 are driven and controlled to lift by the first drive assembly 35, and the rear side plate 31 is driven and controlled to lift by the second drive assembly 36. The control steps are as follows:

[0043] The plunger pump draws oil from the hydraulic oil tank assembly and outputs high-pressure oil to the five-way manual directional valve, which in turn controls each set of cylinders. The five handles of the five-way manual directional valve independently control five hydraulic circuits. The control valve handles 1 and 2 of the five-way manual directional valve each control the two sets of limit locking hydraulic cylinders 330 of each locking assembly 33. In addition, the control valve handles 3, 4, and 5 control the second drive assembly 36 (lifting hydraulic cylinder) of the rear side plate 31 and the first drive assembly 35 (lifting hydraulic cylinder) of the two transverse side plates 30, respectively. The telescopic limiting and locking hydraulic cylinder 330 is driven by control valve handles 1 and 2. The limiting and locking hydraulic cylinder 330 then pushes the first limiting wedge 332 through the first locking link 337 and the second limiting wedge 333 through the second locking link 338. The first limiting wedge 332 and the second limiting wedge 333 rotate (oscillate) around the constraint support block 3341 in an arc. The first limiting wedge 332 and the second limiting wedge 333 rotate along the inclined angle and respectively embed into the locking and limiting plate. On the first limiting shoulder 3200 and the second limiting shoulder 3201 on both sides of the top of the 320, the first limiting wedge 332 and the second limiting wedge 333 are pressed down on the corresponding shoulders of the locking limiting plate 320 by the corresponding connecting rods. Due to the angle, the deeper the first limiting wedge 332 and the second limiting wedge 333 are pressed down, the greater the locking force. When locked in place, the first limiting wedge 332 and the second limiting wedge 333 strike the shoulders of the locking limiting plate 320, producing a mechanical collision sound. Unlocking is the opposite; when the cylinder retracts, the limiting locking hydraulic cylinder 330 pulls the first limiting wedge 332 away from the corresponding shoulder position of the limiting plate 320 via the first locking connecting rod 337 and the second limiting wedge 333 away from the corresponding shoulder position of the limiting plate 320 via the second locking connecting rod 338. In the working state, such as... Figure 13 The overall operating sequence is as follows: First, operate the control valve handles 3, 4, and 5 of the five-way manual directional valve to raise the rear side plate 31 first, then raise the two transverse side plates 30; then operate the control valve handles 1 and 2 of the five-way manual directional valve to complete the self-locking of the two transverse side plates 30 by the first and second limit wedges 332 and 333 of the locking assembly 33. The transport state switching enables, for example... Figure 14First, operate the control valve handles 1 and 2 of the five-way manual directional valve to release the self-locking mechanism. Then, operate the control valve handles 3, 4, and 5 of the five-way manual directional valve to achieve folding. The plunger pump can collect the actual working pressure in real time through the oil inlet no-load sensor of the hydraulic cylinder and feed the signal back to the five-way manual directional valve of the plunger pump to automatically adjust the output load pressure of the plunger pump, ensuring that the hydraulic cylinder works as needed and under the actual pressure.

[0044] The above description is only a preferred embodiment of the utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be considered within the scope of protection of the utility model.
