Description

Technical Field

[0001] The present application relates to the technical field of weeding in rice planting, and in particular to weeding equipment used for rice planting. Background Art

[0002] Rice refers to the grain without removing the husk. Botanically, it belongs to the common rice subspecies in the common cultivated rice subgenus of the genus Oryza in the family Poaceae. Humans have confirmed a total of 22 types of rice, but the only one used in bulk trade is common rice. A lawn mower is also called a lawn mower, lawn mower, lawn trimmer, etc. A lawn mower is a mechanical tool for mowing lawns, vegetation, etc. It consists of a cutter disc, an engine, a running wheel, a running mechanism, a blade, an armrest, and a control part. The cutter disc is mounted on the running wheel, and an engine is mounted on the cutter disc. A blade is mounted on the output shaft of the engine. The blade uses the high-speed rotation of the engine to increase the speed a lot, which saves the working time of weeding workers and reduces a lot of human resources.

[0003] The existing weeder drives the blade to rotate horizontally at high speed through the engine, and the blade cuts the weeds in the paddy field through high-speed rotation. However, during the rice planting process, the weeds and rice are soaked in water. This horizontal rotating blade will drive a lot of water splashes during the cutting process. The water resistance causes the blade to rotate inefficiently. In addition, the blade is prone to drive a lot of sludge during the rotation process, which is not convenient for observing the weeds in the water, resulting in unsatisfactory weed cutting effect. The blade is also prone to cut off the rice roots during the horizontal cutting process, causing rice necrosis and affecting its yield. Therefore, those skilled in the art provide a weeding device for rice planting to solve the problems raised in the above background technology. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the present application provides a weed control device for rice planting.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] (1) When weeding of rice is required, workers hold the handle and move the pressure plate inside the rice field. The motor drives the differential to rotate through the transmission shaft, and the differential drives the linkage roller to rotate. During the rotation of the linkage roller, the two sets of pressure plates are driven to rotate. The pressure plate is located in the gap of the rice field and moves. A plurality of sharp pressure strips are installed on the surface of the pressure plate. The pressure strips move with the pressure plate. The sharp ends of the plurality of pressure strips will contact the sludge during the movement. The leaves and roots of the weeds will be squeezed where the pressure strips pass, so that the weeds are broken into several sections. In this way, the pressure strips are squeezed to replace the high-speed rotation of the traditional blades, thereby reducing the occurrence of danger. The pressure strips are located in the rice field channel and move to reduce the damage to the rice. The pressure plate and the pressure strips are hollowed out to reduce the walking resistance on the water surface and increase the moving efficiency. The slow cutting efficiency of the pressure strips reduces the splashing of mud and water, which is convenient for workers to observe the rice during the cutting process and minimizes the damage to the rice.

[0017] (2) When the pressure plate is moving, in order to reduce the contact between the motor and water and increase the safety of the motor, the support frame is tilted upward, so that the staff needs to lift the motor to move, which puts a heavy load on the staff's waist. The auxiliary support assembly supports the bottom of the support frame to reduce the force applied during the lifting process and reduce damage to the staff's waist. The auxiliary support assembly consists of a support plate, a pillar, a connecting frame and auxiliary wheels. The two sets of auxiliary wheels move in the same straight line as the pressure plate to reduce the crushing of the rice. The support plate facilitates the horizontal fixing of the pillar. The two sets of auxiliary wheels are located on the surface of the connecting frame and rotate, reducing the friction between the auxiliary support assembly and the mud and water and facilitating the movement of the auxiliary support assembly.

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-4 This application is described in further detail.

[0024] The present application embodiment discloses a weed removal device for rice planting. Figure 1-4The weed control equipment for rice planting includes a shell 1, a support frame 3, a handle 5 and an auxiliary support assembly 9, one end of the shell 1 is fixedly connected to a motor 2, one side output end of the motor 2 is provided with a differential 6 through a transmission shaft penetrating the shell 1, and linkage rollers 7 are provided on both sides of the differential 6, and pressure plates 71 are sleeved on the surfaces of the two groups of linkage rollers 7, and a plurality of pressure strips 72 are equidistantly inserted on the surface of the pressure plate 71, and the support frame 3 is arranged above the shell 1, and a baffle 4 is arranged above the support frame 3, and the baffle 4 is located above the motor 2, and the handle 5 is arranged on the side of the support frame 3 away from the differential 6, and the auxiliary support assembly 9 is arranged on the support frame 3 and located on the side of the linkage roller 7 close to the support frame 3;

[0025] In this way, during the implementation process, when it is necessary to weed the rice, the worker moves through the handgrip 5 through the pressure plate 71 located inside the rice field, the motor 2 drives the differential 6 to rotate internally through the transmission shaft, the differential 6 drives the linkage roller 7 to rotate, and the linkage roller 7 drives the two groups of pressure plates 71 to rotate during the rotation of the linkage roller 7, the pressure plate 71 is located in the gap of the rice field and moves, a plurality of sharp layering strips 72 are installed on the surface of the pressure plate 71, the layering strips 72 move with the pressure plate 71, and the sharp ends of the plurality of layering strips 72 will contact the sludge during the movement, and the blades and roots of the weeds will be squeezed where the layering strips 72 pass, so that the weeds are broken into several sections, so that the layering strips 72 are squeezed in the way of squeezing instead of the high-speed rotation of the traditional blade, and the occurrence of danger is reduced, and the layering strips 72 are located in the rice field channel and move, reducing the damage to the rice, and the pressure plate 71 and the layering strips 72 are hollowed out to reduce the walking resistance on the water surface and increase the moving efficiency;

[0026] When workers push the pressure plate 71 forward, the support frame 3 supports the baffle 4 and the handle 5. The handle 5 is convenient for workers to grasp, and the baffle 4 can protect the top of the motor 2. The bottom of the support frame 3 is supported by the auxiliary support assembly 9, so that the support frame 3 can move at a relatively stable angle, reducing the force applied by people and reducing work intensity.

[0027] Among them, a mudguard 8 is provided on the surface of the outer shell 1, and the mudguard 8 is located on the side of the linkage roller 7 close to the handle 5. The mudguard 8 is arc-shaped and can wrap one side of the linkage roller 7. When the linkage roller 7 and the pressure strip 72 drive mud and water to be thrown toward the workers, the arc-shaped mudguard 8 can block the mud and water, thereby increasing the safety of the workers.

[0028] Preferably, anti-skid rubber sleeves 51 are fixedly connected to the two side surfaces of the handle 5, and the surface of the anti-skid rubber sleeves 51 are cross-cut with anti-skid patterns. The anti-skid rubber sleeves 51 are located at both ends of the handle 5. The handle 5 increases surface friction through the anti-skid rubber sleeves 51, which increases the stability of the staff when grasping and prevents the hand from slipping.

[0029] Specifically, the auxiliary support assembly 9 includes a support plate 91 fixedly connected to the lower part of the support frame 3, a support column 92 is provided below the support plate 91, a connecting frame 93 is provided below the support column 92, and auxiliary wheels 94 are plugged into both ends of the connecting frame 93, and the auxiliary wheel 94 is located on one side of the pressure plate 71;

[0030] In order to reduce the contact between the motor 2 and water and increase the safety of the motor 2 during the walking of the pressure plate 71, the support frame 3 is tilted upward, so that the staff needs to lift the motor 2 to move, which puts a heavy load on the staff's waist. The auxiliary support assembly 9 supports the bottom of the support frame 3 to reduce the force used by the staff during the lifting process and reduce the damage to the staff's waist. The auxiliary support assembly 9 is composed of a support plate 91, a pillar 92, a connecting frame 93 and an auxiliary wheel 94. The two sets of auxiliary wheels 94 move in the same straight line as the pressure plate 71 to reduce the crushing of rice. The support plate 91 facilitates the horizontal fixation of the pillar 92. The two sets of auxiliary wheels 94 are located on the surface of the connecting frame 93 and rotate, reducing the friction between the auxiliary support assembly 9 and the mud and water and facilitating the movement of the auxiliary support assembly 9.

[0031] More specifically, the support column 92 includes a fixed column 921 fixedly connected to the bottom of the support plate 91, a support spring 922 is arranged inside the fixed column 921, a connecting rod 923 is arranged below the support spring 922, a telescopic rod 924 is arranged below the connecting rod 923, and the bottom of the telescopic rod 924 is sleeved on the surface of the connecting frame 93;

[0032] The support spring 922 supports the connecting rod 923 and the telescopic rod 924, and the telescopic rod 924 fixes the connecting frame 93. When the staff puts down the handle 5, the support frame 3 is in direct contact with the ground, and the vibration can easily cause damage to the motor 2. The support spring 922 provides a certain buffering performance for the connecting rod 923 and the telescopic rod 924, thereby increasing the safety of the motor 2 during use. The ground in the rice field is difficult to level, and the auxiliary support component 9 can play a buffering role when encountering potholes, thereby increasing the safety of personnel use.

[0033] Further in the implementation process, a slider 925 is fixedly connected to the top of the telescopic rod 924, and the telescopic rod 924 and the slider 925 are both located inside the fixed column 921 for sliding. A limiting column 926 is sleeved on the surface of the connecting rod 923, and the limiting column 926 is located on the surface of the supporting spring 922, and the top of the limiting column 926 is fixedly connected to the inner wall of the fixed column 921;

[0034] The telescopic rod 924 is located inside the fixed column 921. During the sliding process of the telescopic rod 924, the slider 925 is driven to slide. One side of the slider 925 protrudes from the outside of the fixed column 921, which is convenient for personnel to observe the height of the slider 925. The outer wall of the slider 925 fits with the inner wall of the fixed column 921 to reduce the entry of sludge through the gap. The limiting column 926 limits the connecting rod 923 to increase the sliding stability of the connecting rod 923. At the same time, the limiting column 926 protects the internal support spring 922 to reduce the corrosion of the support spring 922 caused by air entry and increase the service life of the support spring 922.

[0035] The implementation principle of the weeding device for rice planting in the embodiment of the present application is as follows: when it is necessary to weed the rice during use, the worker moves inside the rice field by holding the handle 5, and the pressure plate 71 is located inside the rice field. The motor 2 drives the differential 6 to rotate inside through the transmission shaft, and the differential 6 drives the linkage roller 7 to rotate. During the rotation of the linkage roller 7, the two groups of pressure plates 71 are driven to rotate. The pressure plate 71 is located in the gap of the rice field and moves. A plurality of sharp pressure strips 72 are installed on the surface of the pressure plate 71. The pressure strips 72 move with the pressure plate 71. The sharp ends of the plurality of pressure strips 72 will contact with the sludge during the movement. The places where the pressure strips 72 pass will squeeze the leaves and roots of the weeds, so that the weeds The grass is broken into several sections, so that the squeezing method of the pressure strip 72 replaces the high-speed rotation of the traditional blade, which reduces the occurrence of danger. The pressure strip 72 is located in the rice field channel and moves to reduce damage to the rice. The pressure plate 71 and the pressure strip 72 are hollowed out to reduce the walking resistance on the water surface and increase the moving efficiency. When the worker pushes the pressure plate 71, the support frame 3 supports the baffle 4 and the handle 5. The handle 5 is convenient for the staff to grasp. The baffle 4 can protect the top of the motor 2. The bottom of the support frame 3 is supported by the auxiliary support assembly 9, so that the support frame 3 moves at a relatively stable angle, reducing the force applied by personnel and reducing the work intensity.
