Description

Technical Field

[0001] The invention relates to the field of municipal engineering, in particular to a self-adjusting road salt spreading device. Background Art

[0002] In winter, after precipitation and snowfall, the road surface is prone to ice formation, which makes the road surface slippery and impossible to walk on, affecting traffic safety, especially in some remote areas such as highways and mountain roads, which are not easy to clean in time. At present, the commonly used method is to spread salt; spreading salt can melt ice and snow, and at the same time increase friction. Salting is generally done by manual and mechanical methods. Most machines are a high-speed rotating disk, which can quickly spread salt through impact and centrifugal force.

[0003] This method of salting is highly efficient, but wasteful, and the amount of salt spread on both sides of the road is significantly more than that in the middle of the road. At the same time, the road conditions are complex, and in most cases, local low-lying areas will form regional ice. Therefore, in most cases, comprehensive salting is not necessary, and current equipment cannot achieve the effect of local salting. Summary of the invention

[0024] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings.

[0025] Depend on Figures 1 to 5The present invention comprises a silo 1 placed in the front-to-back direction, and travel wheels 2 are installed on both the front and rear sides of the silo 1; a crossbeam 3 is fixed to the middle of the right side of the silo 1, and a vertical front support wheel 4 is installed on the crossbeam 3;

[0026] The bottom of the silo 1 is provided with a plurality of discharge holes 5, and each discharge hole 5 is provided with a distributor 6 above; the distributor 6 can control the discharge speed; the bottom of the silo 1 is provided with a screen box 7 that can swing back and forth, and the bottom of the screen box 7 is a screen 8;

[0027] The distributor 6 comprises a rotating shaft 601 disposed at the axis of the discharge hole 5; a spiral blade 602 is mounted on the rotating shaft, and two left and right baffles 603 are provided below the discharge hole; the two baffles can be reset toward the rotating shaft and block the discharge hole; two left and right motors 605 are provided below the discharge hole, and a wire wheel 606 is mounted on the motor, and ropes 607 are respectively connected between the left and right wire wheels and the left and right baffles; the rotation of the motor can pull the baffle away from the rotating shaft;

[0028] A control rod 9 that can move up and down is installed at the rear of each of the distributors 6, a control wheel 10 is installed at the lower end of the control rod 9, a displacement sensor 11 is arranged on the control rod 9, and a rotation sensor 12 is installed on the control wheel 10; the signals of the rotation detector and the displacement sensor 11 are processed by the single chip microcomputer to control the rotation angle of the motor 605.

[0029] In order to control the left and right movement of the baffle, when the control wheel 10 rotates, the rotation sensor 12 has a signal, and the motor 605 is reset at this time, so that the baffle is reset toward the direction of the rotating shaft; when the control wheel 10 stops, the rotation sensor 12 has no signal, and the rotation angle of the motor 605 is positively correlated with the assigned value of the displacement sensor 11 signal.

[0030] In order to realize the installation and resetting of the baffle, a slide groove 608 is fixed at the end of the silo 1, and the baffle is installed in the slide groove; a compression spring 609 is connected between the baffle and the motor.

[0031] In order to facilitate the adjustment of the resistance of the control wheel 10 , a clamping bolt 13 capable of squeezing the control wheel 10 is installed on the control rod 9 .

[0032] In order to realize the sliding installation of the screen box 7, the bottom of the silo 1 and the top of the screen box 7 are installed via a slide rail.

[0033] In order to realize the installation and downward resetting of the control rod 9, a bracket 14 is provided on the silo 1. The control rod 9 passes through the bracket 14 and can move up and down along the bracket 14. A tension spring is installed on the control rod 9. The upper end of the tension spring is fixed to the upper end of the control rod 9, and the lower end of the tension spring is fixed to the bracket 14.

[0034] In order to realize the simultaneous rotation of the rotating shafts 601 in multiple distributors 6 and the swinging of the screen box 7; two front and rear support blocks 15 are installed at the bottom of the silo 1, and a main shaft 16 in the front and rear directions passes through the two front and rear support blocks 15, and a plurality of first bevel gears are installed on the main shaft 16, and a second bevel gear meshing with the first bevel gear is installed at the lower end of each rotating shaft 601; the middle part of the main shaft 16 is a bidirectional lead screw 17, and a nut 18 is mounted on the bidirectional lead screw 17, and the nut 18 is fixedly connected to the screen box 7 via a connecting rod 19.

[0035] In order to realize the rotation of the main shaft 16, the mounting shaft of the traveling wheel 2 is linked to the main shaft 16 via a belt and a pulley.

[0036] When the present invention is used, the crossbeam 3 of the device is first connected to the rear end of the construction vehicle. After the connection is completed, the front support wheels 4 on the device will be off the ground, so that the entire device remains attached. Figure 1 The state shown, that is, the silo 1 is kept facing upward, and then the required crude salt and other components can be added into the silo 1. The upper end of the silo 1 is properly covered to prevent it from getting wet in rainy days.

[0037] Anti-skid chains can be arranged outside the running wheel 2 to prevent the running wheel 2 from slipping, and some heavy objects can be appropriately added above the device to further prevent the running wheel 2 from slipping.

[0038] Then, the vehicle can be started to drag the device along the road. In the device, the distributor 6 is arranged as a plurality of distributors along the front-rear direction, and each distributor 6 is equipped with a control rod 9 and a control wheel 10, that is, each distributor 6 is controlled separately.

[0039] When walking, the walking wheel 2 will rotate, thereby driving the main shaft 16 to rotate, and then the rotation of the main shaft 16 will drive the rotating shafts 601 in multiple distributors 6 to rotate simultaneously; at the same time, since a bidirectional screw 17 is arranged in the middle section of the main shaft 16, the bidirectional screw 17 will drive the nut 18 to reciprocate, and then the screen box 7 will reciprocate.

[0040] The coarse salt in the silo 1 is controlled by the distributor 6 and flows into the screen box 7 from the discharge hole 5. The screen box 7 is shaken and can be sprinkled on the road surface. The shaking of the screen box 7 can prevent agglomeration, making the coarse salt more evenly spread and avoiding the salt being distributed in thin strips after being spread.

[0041] In addition, the device is provided with a control rod 9 and a control wheel 10. The control wheel 10 is in contact with the ground and will rotate or not rotate as the device moves, mainly depending on the friction of the ground. When there is no ice or snow on the ground, the control wheel 10 can rotate, and when there is ice and snow on the ground, the control wheel 10 slips and does not rotate. Then the rotation sensor 12 detects the change, so that the motor 605 of the distributor 6 is controlled to rotate through the single chip microcomputer.

[0042] When there is no ice on the ground, there is no need to spread salt. In this state, the control wheel 10 rotates, and the rotation sensor 12 outputs a signal. The single chip computer will control the motor 605 to keep the motor 605 in a reset state. At this time, the single chip computer ignores the signal of the displacement sensor 11. The control of the distributor 6 is realized, the spilling of salt is saved, and unnecessary waste is avoided. Since multiple distributors 6 are controlled separately, when a distributor 6 closes the discharge port, it does not affect the remaining distributors 6. The purpose of identifying the road surface area and spreading salt as needed is realized.

[0043] When there is ice on the ground, the control wheel 10 stops rotating and the rotation sensor 12 has no signal output. At this time, the single chip will adjust the rotation angle of the motor 605 according to the signal of the displacement sensor 11, thereby controlling the degree of movement of the baffle. Because there is ice and snow on the ground, the control rod 9 will rise relatively; the thicker the ice and snow, the greater the degree of movement; further, the value assigned to the displacement sensor 11 becomes larger, and the single chip will adjust the rotation angle of the motor 605 according to the value assigned to the displacement sensor 11, so that the distance moved by the baffle becomes larger; thereby, the degree to which the discharge hole 5 is opened also becomes larger. The effect of being able to spread more coarse salt on thick areas of ice and snow is achieved.

[0044] At the same time, there is a spiral blade 602 inside the distributor 6. When the material is discharged from the silo 1, the spiral blade 602 will assist in the discharge of the material to prevent the material from agglomerating and clogging the discharge hole 5, thereby ensuring smooth discharge.
