Description

Technical Field

[0001] The invention relates to the technical field of sand prevention devices, in particular to a brush-shaped grass rope weaving device for annular track type grass grids. Background Art

[0002] At present, the materials used to fix quicksand in desert areas are mainly ordinary wheat straw or rice straw grids. Usually, wheat straw or rice straw after grain is threshed is used as the raw material for the grids. It is laid on the sand dunes in the shape of a grid. The straw is buried 15-20 cm with a shovel or a grid machine. The two ends of the straw are raised and extend about 10-20 cm above the sand surface. Due to the harsh natural conditions in desert areas, high daytime temperatures, large temperature differences between day and night, and strong wind and sand damage, ordinary grid sand barriers usually rot and are destroyed in one to two years, losing their sand fixation function.

[0003] Chinese patent application CN111778743A discloses a "production device for brush-shaped net ropes for grass grid sand barriers", including a grass rope and straw curtain input guide plate device, a rotating drum device, a traction trolley device, a trolley track device and a grass rope bracket device. The grass rope and straw curtain input guide plate device includes a guide plate, a pressure plate, an upward grass rope guide wheel, a downward grass rope first guide wheel, a downward grass rope second guide wheel and a control switch; the two ends of the guide plate are installed on a bracket, the upward grass rope is introduced into the guide plate through the upward grass rope guide wheel installed on a bracket on one side of the guide plate, and the downward grass rope is introduced into the guide plate through the downward grass rope first guide wheel and the downward grass rope second guide wheel installed on the bracket; the control switch is installed on a bracket on one side of the guide plate, and is electrically connected to the power box wire of the control motor, and is used to start and stop the motor operation. The device is to place two grass ropes on the feeding device, with a straw curtain in the middle. There is a tractor behind the frame to pull the grass rope backwards and rotate the grass rope at the same time, so that a brush-shaped grass rope is formed. The brush-shaped net rope is durable and has a long service life. However, the device has the following shortcomings: when the grass rope reaches a certain length during the preparation of the brush-shaped grass rope, the device must be stopped, the formed grass rope must be cut, and the tractor must be restarted after it comes back; after the grass rope is cut, the mouth must be tied tightly with a thin wire and then hung on the tractor. The whole process requires three people. During the return to hang the grass rope, the device is in a shutdown state, and the tractor comes back empty-handed, which increases labor, wastes time, and has low production efficiency in preparing the brush-shaped grass rope. Summary of the invention

[0004] The purpose of the present invention is to provide a track-type brush-shaped grass rope production device which can work continuously, has high preparation efficiency and requires fewer operators, in view of the problems existing in the existing production devices of brush-shaped grass ropes for grass grid sand barriers.

[0005] The technical solution of the present invention is as follows: a brush-shaped grass rope weaving device for annular track type grass grid is installed on an annular frame. Two groups of traction trolleys are installed on the annular track. An annular chain is also installed next to the annular track. The transmission device of the annular chain is composed of a driving sprocket and a driven sprocket, which are meshed with the annular chain. Sensor 1 and sensor 2 are respectively arranged at both ends of the annular track, and a central controller is arranged on the annular frame. Driven by the reduction motor, the driving sprocket and the driven sprocket drive the annular chain to push the traction trolley forward. The annular chain drives the traction trolley to move continuously in one direction on the annular track. A servo motor and an electric scissors are loaded on the traction trolley. Feeding devices for weaving grass ropes are arranged at both ends of the annular track. When the traction trolley runs to both ends of the circular track, the touch sensor 1 transmits a signal to the central controller, and the central controller issues a command. The servo motor on the traction trolley cooperates with it, and the clamp receives the command and clamps the material transmitted from the feeding device. The servo motor shaft rotates to drive the clamp to rotate. When the traction trolley pulls the material, the material is twisted into a brush-like straw rope. When the clamp clamps the material to weave the straw rope to a certain length, the scissors on the electric scissors cut the straw rope. At this time, the straw rope that has been woven in front falls down and waits to be transported away. When the traction trolley runs to the other end of the straight section of the circular track, the touch sensor 2 is triggered. Under the command of the central controller, the clamp automatically opens, and one end of the woven straw rope falls down. The clamp remains in the initial static state, and the traction trolley continues to move forward along the circular track. After the circular track turns 180 degrees, the next action is repeated in a cycle.

[0006] The two traction trolleys are symmetrically distributed on the circular track and simultaneously complete the same action corresponding to the weaving of the traction material rope. The entire operation process is controlled by the central controller installed on the circular track. The reduction motor is powered by an external power supply, and the servo motor and central controller matched with the traction trolley are powered by batteries, thus avoiding the defect of line entanglement caused by fixed wire circuit power supply.

[0007] The present invention has the following beneficial effects: 1. Due to the setting of the circular track, the entire operation process of the device for weaving straw ropes is uninterrupted, and it works in a continuous cycle, and the weaving efficiency of straw ropes is high.

[0008] 2. The servo motor and electric scissors of the device and the traction trolley are controlled by the central controller and work automatically upon instructions, with accurate and efficient operation.

[0009] 3. Feeding devices are set at both ends of the circular track to feed materials, so the track is not empty back and forth, which improves the working efficiency of the traction trolley. When two groups of trolleys work at the same time, the efficiency is doubled. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0012] In order to more clearly understand the embodiments of the present invention, further description will be given below in conjunction with embodiments.

[0013] Example 1: Please see Figures 1 to 6, a brush-shaped grass rope weaving device for circular track type grass grid, a circular track 101 is installed on the circular frame 700, two groups of traction trolleys 120 are installed on the circular track 101, and a circular chain 220 is installed next to the circular track 101. The transmission device of the circular chain is composed of a driving sprocket 210 and a driven sprocket 211, which are meshed with the circular chain 220. Sensor 1 901 and sensor 2 902 are respectively arranged at both ends of the circular track 101, and a central controller 900 is arranged on the circular frame 700. Driven by the reduction motor 230, the driving sprocket 210 and the driven sprocket 211 drive the circular chain 220 to push the traction trolley 120 forward, and the circular chain 220 drives the traction trolley to continuously move in one direction on the circular track 101. A servo motor 310 and an electric scissors 410 are loaded on the traction trolley 120. Feeding devices are arranged at both ends of the circular track 101. When the traction trolley 120 runs to the two ends of the circular track, the sensor 1 901 is touched to transmit a signal to the central controller 900, and the central controller 900 issues a command. The servo motor 310 on the traction trolley 120 cooperates with it, and the clamp 311 receives the command and clamps the material transmitted from the feeding device. The servo motor 310 shaft rotates to drive the clamp 311 to rotate. When the traction trolley 120 pulls the material, the material is twisted into a brush-like straw rope. When the clamp clamps the material to weave the straw rope to a certain length, the scissors 411 on the electric scissors 410 cut the straw rope. At this time, the straw rope that has been woven in front falls down and waits to be transported away. When the traction trolley runs to the other end of the straight section of the circular track, the sensor 2 902 is touched, the clamp 311 automatically opens, and one end of the woven straw rope falls down. The clamp 311 remains in the initial static state, and the traction trolley 120 continues to move forward. After the circular track 101 turns 180 degrees, the next action is repeated in a cycle.

[0014] The two traction trolleys are symmetrically distributed on the circular track 101 and simultaneously perform the same action corresponding to the weaving of the traction material rope. The entire operation process is controlled by the central controller 900 installed on the circular track. The reduction motor 230 is powered by an external power supply, and the servo motor 310 and the central controller 900 matched with the traction trolley 120 are powered by the battery 600.

[0015] The central controller 900 has a built-in PLC or PC chip, which is matched with the sensor 1 901 and the sensor 2 902 set at both ends of the circular track. The sensor senses and transmits signals to the central controller, and the central controller issues corresponding control instructions. Sensors 901 and 902 are installed at the starting point and the end of the straight segment of the circular track 101. When the traction trolley 120 approaches the sensor 901 or the sensor 902, a signal is sent to the central controller 900, and the central controller 900 then issues instructions to command the servo motor 310 and the electric scissors 410 to move.

[0016] The servo motor 310 is a controlled high-precision motor, whose rotation speed and rotation angle are controlled by the central controller 900. The clamping jaw 311 on the servo motor 310 can also return to the initially set working state, which is conducive to the clamping jaw 311 clamping the material. That is, the action of the clamping jaw 311 on the servo motor 310 during the entire cycle is controlled by the instructions of the central controller 900. The servo motor 310 needs to be powered by a battery 600. The above automatic control technology is an existing conventional technology, which can be understood and implemented by existing technicians. As for the specific PLC control program, it can be determined independently by the manufacturer.

[0017] The transmission of the whole device of the present invention is that the reduction motor 230 drives the driving sprocket 210 to rotate, and the driving sprocket 210 cooperates with the driven sprocket 211 to drive the ring chain 220 and the traction trolley 120 to move continuously. The main function of sensor 1 901 and sensor 2 902 is to sense that the traction trolley 120 has reached a predetermined position and send the information to the central controller 900 in time. The sensor can be in the form of a photoelectric induction type or a touch type.

[0018] The servo motor 310 and its clamping jaw 311 are standard components and can be used directly.

[0019] The electric scissors 410 and the scissors 411 are standard assembly parts and can be used directly.

[0020] The material of the brush-shaped straw rope of the present invention can be wheat straw or rice straw, and wheat straw and rice straw substitutes such as reeds can also be used.

[0021] The brush-shaped straw rope woven by the invention is dense and thick, has good sand prevention and fixation effect, is not easy to rot and be damaged when buried in sandy soil, and is convenient for large-scale promotion.
