Description

Technical Field

[0001] This invention relates to the field of sand control devices, and in particular to a brush-shaped straw rope weaving device for a ring-shaped track-type straw grid. Background Technology

[0002] Currently, the main material used to stabilize shifting sand in desert areas is ordinary wheat or rice straw checkerboard patterns. Typically, wheat or rice straw, after the grain has been harvested, is used as the raw material for these checkerboard patterns. These are laid on sand dunes in a checkerboard pattern, and the straw is buried 15-20 centimeters deep using shovels or checkerboard machinery, with the ends of the straw sticking up about 10-20 centimeters above the sand surface. However, due to the harsh natural conditions in desert areas—high daytime temperatures, large diurnal temperature variations, and strong winds—ordinary straw checkerboard sand barriers usually rot and break down within one to two years, losing their sand-stabilizing effect.

[0003] Chinese patent application CN111778743A discloses a "Production Device for Brush-Shaped Net Ropes for Straw Checkerboard Sand Barriers," comprising straw ropes, a straw mat input guide plate device, a rotating drum device, a traction trolley device, a trolley track device, and a straw rope support device. The straw rope and straw mat input guide plate device includes a guide plate, a pressure plate, an upward straw rope guide wheel, a downward straw rope first guide wheel, a downward straw rope second guide wheel, and a control switch. Both ends of the guide plate are mounted on supports. The upward straw rope is guided into the guide plate through the upward straw rope guide wheel mounted on one side of the support, and the downward straw rope is guided into the guide plate through the downward straw rope first guide wheel and the downward straw rope second guide wheel mounted on the support. The control switch is mounted on one side of the support and is electrically connected to the power supply box wire of the control motor for starting and stopping the motor. This device places two straw ropes on a feeding device, with a straw mat sandwiched in between. A traction trolley pulls the straw ropes backward from the rear of the frame, simultaneously rotating them to form brush-shaped straw ropes. The brush-shaped straw rope is durable and has a long service life. However, it has the following drawbacks: When the straw rope reaches a certain length during the production process, the machine must be stopped to cut it. The tractor then has to return and start again. After cutting the straw rope, the ends need to be tied tightly with thin wire before being hung on the tractor. The whole process requires three people. The machine is stopped during the return process, and the tractor returns empty, increasing manpower and wasting time. As a result, the production efficiency of brush-shaped straw rope is low. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the production devices of brush-shaped straw ropes for straw checkerboard sand barriers, and to provide a track-type brush-shaped straw rope production device that can operate continuously, has high production efficiency, and requires fewer operators.

[0005] The technical solution of the present invention is as follows: The brush-shaped straw rope knitting device for the annular track type straw checkerboard. On the annular rack, an annular track is installed. Two traction trolleys are installed on the annular track. Beside the annular track, an annular chain is also installed. The transmission device of the annular chain consists of a driving sprocket and a driven sprocket, which meshes with the annular chain. At both ends of the annular track, a sensor one and a sensor two are respectively arranged. A central controller is arranged on the annular rack. The driving sprocket and the driven sprocket are driven by a reduction motor to drive the annular chain and push the traction trolley forward. The annular chain drives the traction trolley to continuously move in one direction on the annular track. A servo motor and an electric scissors are loaded on the traction trolley. Feeding devices for knitting straw ropes are arranged at both ends of the annular track. When the traction trolley runs to both ends of the annular track, it touches the sensor one and transmits a signal to the central controller. The central controller issues an instruction. The servo motor on the traction trolley cooperates with it. The clamping jaw receives the command and clamps the material transmitted from the feeding device. The rotation of the servo motor shaft drives the clamping jaw to rotate. When the traction trolley pulls the material to run, the material is twisted into a brush-shaped straw rope. When the clamping jaw clamps the material and knits the straw rope to a certain length, the scissors on the electric scissors cut the straw rope. At this time, the previously knitted straw rope falls off and waits to be transported away. When the traction trolley runs to the other end of the straight section of the annular track, it touches the sensor two. Under the instruction of the central controller, the clamping jaw automatically opens. One end of the knitted straw rope falls down. The clamping jaw remains in the initial static state. The traction trolley continues to continuously move forward along the annular track. After the annular track turns a 180-degree bend, the next action is repeated in a cycle.

[0006] The two traction trolleys are symmetrically and evenly distributed on the annular track and simultaneously complete the same corresponding actions of pulling materials and knitting straw ropes. The entire operation process is controlled by the central controller installed on the annular track. The reduction motor is powered by an external power supply. The servo motor and the central controller supporting the traction trolley are powered by batteries, thus avoiding the defect of wire entanglement caused by fixed wire circuit power supply.

[0007] The present invention has the following beneficial effects: 1. Due to the setting of the annular track, the entire operation process of knitting straw ropes by this device is uninterrupted, continuously circulates and works, and the efficiency of knitting straw ropes is high.

[0008] 2. The servo motor and the electric scissors supporting the traction trolley of this device are automatically controlled by the central controller to issue instructions and work accurately and efficiently.

[0009] 3. Feeding devices are respectively arranged at both ends of the annular track for feeding work, without being empty back and forth, improving the working efficiency of the traction trolley. The two groups of trolleys work simultaneously, doubling the efficiency. Description of the Drawings

Detailed Implementation

[0012] To better understand the embodiments of the present invention, further explanation will be provided below in conjunction with examples.

[0013] Example 1: Please refer to Figures 1 to 6, The brush-shaped straw rope weaving device for the annular track type straw checkerboard. On the annular rack 700, an annular track 101 is installed. Two sets of traction trolleys 120 are installed on the annular track 101. Beside the annular track 101, an annular chain 220 is installed. The driving device of the annular chain consists of a driving sprocket 210 and a driven sprocket 211, which meshes with the annular chain 220. At both ends of the annular track 101, a sensor one 901 and a sensor two 902 are respectively arranged. A central controller 900 is arranged on the annular rack 700. The driving sprocket 210 and the driven sprocket 211 are driven by a reduction motor 230 to drive the annular chain 220 and push the traction trolley 120 to move forward. The annular chain 220 drives the traction trolley to continuously move in one direction on the annular 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 annular track 101. When the traction trolley 120 runs to both ends of the annular track, it touches the sensor one 901 and transmits a signal to the central controller 900. The central controller 900 issues an instruction. The servo motor 310 on the traction trolley 120 cooperates with it. The clamping jaw 311 receives the command and clamps the material transmitted from the feeding device. The shaft of the servo motor 310 rotates to drive the clamping jaw 311 to rotate. When the traction trolley 120 pulls the material to run, the material is twisted into a brush-shaped straw rope. When the clamping jaw 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 previously woven straw rope falls off and waits to be transported away. When the traction trolley runs to the other end of the straight section of the annular track, it touches the sensor two 902, and the clamping jaw 311 automatically opens. One end of the woven straw rope falls down. The clamping jaw 311 remains in the initial static state, and the traction trolley 120 continues to move forward continuously. After the annular track 101 turns a 180-degree bend, the next action is repeated in a cycle.

[0014] The two traction trolleys are symmetrically and evenly distributed on the annular track 101 and simultaneously complete the same corresponding actions of pulling the material to weave the straw rope. The entire operation process is controlled by the central controller 900 installed on the annular track. The reduction motor 230 is powered by an external power supply, and the servo motor 310 and the central controller 900 supporting the traction trolley 120 are powered by a battery 600.

[0015] The central controller 900 is internally provided with a PLC or PC chip, which is matched with the sensor one 901 and the sensor two 902 arranged at both ends of the annular track. Signals are transmitted to the central controller through sensor induction, and the central controller issues corresponding control instructions. Sensors 901 and 902 are installed at the starting point and the end of the straight section of the annular track 101. When the traction trolley 120 approaches the sensor 901 or the sensor 902, it sends a signal to the central controller 900, and the central controller 900 then issues an instruction to command the movement of the servo motor 310 and the electric scissors 410.

[0016] The servo motor 310 is a high-precision electric motor that is controlled by a central controller 900. Its rotation speed and angle are controlled by the central controller 900. The gripper 311 on the servo motor 310 can return to its initially set working state, which is beneficial for the gripper 311 to hold the material. In other words, the movement of the gripper 311 on the servo motor 310 throughout the entire cycle is controlled by commands from the central controller 900. The servo motor 310 requires a battery 600 for power. The above automatic control technology is existing conventional technology, which can be understood and implemented by existing technicians. The specific PLC control program can be determined by the manufacturer.

[0017] The transmission of the entire device in this invention is achieved by a geared motor 230 driving a drive sprocket 210 to rotate. The drive sprocket 210, in conjunction with a driven sprocket 211, drives the annular chain 220 and the traction trolley 120 to move continuously. Sensors 901 and 902 primarily function to detect when the traction trolley 120 reaches a predetermined position and promptly transmit the information to the central controller 900. These sensors can be photoelectric or contact-based.

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

[0019] Electric scissors 410 and 411 are standard assembly parts. They can be used directly.

[0020] The material used to weave the brush-shaped straw rope of this invention can be wheat straw or rice straw, or it can be a substitute for wheat straw or rice straw such as reeds.

[0021] The brush-shaped straw rope woven by this invention is dense and robust, with good sand prevention and fixation effects. It is not easily rotted or damaged when buried in sand, making it easy to promote on a large scale.
