Remote weeding machine

Abstract

The hand-held weeder (remote) is a tool in the agricultural field for cutting weeds and red rice in the rice field at the time of harvest (when the rice spikes are yellow and ready for the combine). The function of this device is that the farmer stands on the main border of the rice field and, by pressing the brake-like handle (bicycle brake handle) which is connected to the weed-collecting branches by a wire, collects the weeds and red rice in one direction and on a straight line. In the second stage, by pulling the retractable handle (like a hoe), Connected to the weed cutting blade, the blade moves on its rail in the direction of the collected weeds, and this movement causes the weeds to be cut. In the third stage, the cut weeds are held with the help of mesh boxes installed on both sides. After the weed cutting operation is completed, the farmer empties the weeds collected in the box onto the main border of the land and the device is ready for the cutting operation again. With this device, the speed of weed cutting is increased, resulting in less manpower and less cost, and the quality of the rice is also maintained. Be.

Description

Description of the invention Title of the invention Manual weeding device (remote) Technical background of the relevant invention This invention is related to the field of agriculture. With the help of this device, weeds and red rice in the paddy field can be pruned, and then the farmer places the cut weeds and red rice on the main border of the land. Technical problem and stating the objectives of the invention The quality of agricultural products plays a major role in the selling price of the product and consumer consumption (cleaning rice). Weeds and red rice in the rice field cause weed seeds and red rice to mix with paddy (rice with husk) and the product loses its quality. To eliminate these weeds and red rice, the farmer must enter the rice field and prune these weeds, because this usually happens at harvest time (when the paddy clusters are yellow and ripe and there is no gap between the rice seedlings), which causes a portion of the product to fall with minimal shaking and pressure. Since these weeds and red rice are spread in clusters on the ground, it takes a long time to prune the land, because it must be done at a slow speed and carefully so that the amount of rice clusters falling is reduced (it takes about a week to ten days to prune one hectare). Weeds and red rice, because they are higher than the rice, cast shadows on the rice field, which causes the crop in that area to turn yellow later and leads to excessive drying of other parts of the rice field (because the farmer waits for the entire field to turn yellow, which delays the time for harvesting the ripe crop. If the rice dries out too much in the rice field, when the paddy is taken to the factory to be processed into rice, a large percentage of it will be converted into rice meal). The manual weeding machine with three mechanisms prunes, collects and transfers weeds to the main border of the paddy field, reducing the time required for this work (because the farmer is outside the paddy field and does not need to move at a slow speed, but does this at a faster speed). A description of the state of the prior art and the history of developments related to the claimed invention. Usually, to eliminate weeds, farmers pour poison into the paddy field at the time of loosening or when the seedlings first sprout. When the seedlings have completely sprouted and become green, the farmer enters the field (using his feet and hands) and prunes any weeds if they are present. The devices and tools used are related to this part (the time of re-sprouting). The farmer can easily move around the paddy field and do the pruning. However, when it is time to harvest the crop, because the seedlings have completed all their growth and the upper part of the stems have collapsed and the rice ears are placed on them, preventing the farmer from moving into the paddy field. In the invention of the hand-held wheeled weeder (without a motor) with registration number 75262, which was disclosed in 2011, the invention has wheels, so it is not possible to move between the rice fields due to reasons such as the loose environment of the rice fields and the wheels getting stuck, and secondly, there is no distance between the crops during harvesting that can be moved between. In the invention of a mechanical weeding device (with the ability to be connected to a tractor) with registration number 49834, which was disclosed in 1999, according to the inventor, the soil surface must be dry and there is no path for the tractor to move. In the invention of the optical weeder and weed killer with registration number 68288, which was disclosed in 2010, this invention is specific to the cultivation stage. At the time of cultivation, the weed stems are thin and can be destroyed by reflecting light. However, at the time of harvesting, the weed stems have leaves and are strong, and this is not possible, and after cutting the weeds, they are thrown onto the paddy field. In the invention of a paddy field paddler with registration number 68720, which was disclosed in 2010, this device is used for tillage and weeding and operates in the lower area of ​​the crop. Since it is not possible to till the soil and move the device during harvest, this device does not have the necessary efficiency. The invention of weeding (hand cultivator) with registration number 60190, which was disclosed in 2009, is a wheeled device and is intended for fields with row crops and dry soil. Therefore, it is not useful during harvest when the crop is tied together because it is not possible to move and the environment is loose. In the invention of a multi-purpose motorized weeder with registration number 88285, which was disclosed in 2014, it is mentioned that this device is specifically for weeds where the crop is planted in rows and because there is no gap between the crops at harvest time, it is not possible to use it. In the invention of a special weeder for paddy fields with registration number 66846, which was disclosed in 2010, the device performs the tillage operation, so it must move through the crop and be in contact with the soil, which is not possible to move through the crop during harvesting. In the invention of the basket breaker - electromechanical and automatic weeder of agricultural products with registration number 105363, which was disclosed in 1400, this device is used for fields of lettuce, celery, sugar beets, etc., where the land is both dry and cultivated in rows. Weeding machines are usually made to move and perform weed pruning. The surface of the environment must be dry and firm to allow the machine to move. In other cases, the weeding machine must have a special place to move, which usually allows the machine to perform pruning between crops with minimal contact with the crop. Another thing that can be mentioned is that these devices usually perform pruning in the early stages of crop cultivation, mainly in the lower part of the crop, which is used. The weeds are small in size, and if they are pruned and not collected, they dry out and do not cause much disturbance to the crop. This is taken into account in some devices and they have nothing to do with the cut weeds. However, in the harvest stage, weeds, like the crop, have seeds and if they are not collected, they cause impurities in the crop. This feature has been taken into account in the remote weeding device. Providing a solution to an existing technical problem along with an accurate, sufficient, and integrated description of the invention Weeds enter the rice field for various reasons, such as a decrease in water and its semi-drying, or with the seedlings during the planting stage of rice seedlings, or they grow in the rice field through animal waste in the fall, etc. Weeds, by growing in the middle of the rice, can have a reducing effect on the growth of rice. At the stage when the paddy field is ready to harvest, in addition to causing impurities and poor quality of rice, because the height of weeds is sometimes higher than the surface of the rice and causes their shadow to fall on the rice, which in turn causes the rice clusters to turn yellow late and one must wait until the unyellowed parts turn yellow, which leads to excessive drying of the rice and as a result, the rice is crushed during the stage of separating the paddy husk (rice with husk) and converting it into rice. Removing weeds in rice fields by workers is the most common and common method of controlling weeds. Weeding rice fields in most of the northern regions of Iran and areas where rice is cultivated is done by hand and is rarely done by hand weeding machines. The manual weeding device (remote) helps to remove weeds and red rice that are about 10-15 centimeters above the rice surface and in the form of bushes with three mechanisms: collecting weeds and red rice in one direction and on a straight line, then moving the weed cutting blade on the rail that is in the direction of the collected weeds, and then the cut weeds fall into the surrounding box and the farmer empties them on the main border of the land. By pressing the brake-like handle (two-wheel brake handle) connected to the weed-collecting branches, the branches are collected and the weeds are placed in one direction. Considering that the thinner the thickness, the better the cutting action. When the branches come closer together, the weeds are placed in one direction on a straight line. Then, by pulling the sliding handle (like a pulley) connected to the weed-cutting blade, the blade moves on its rail, which is in the direction of the collected weeds, resulting in the cutting of the weeds in its path. Then, the cut weeds fall into the boxes on both sides of the weed-collecting branches. After the farmer finishes cutting the weeds in each plot (each section of the paddy field), he empties them on the main border and the machine is ready to cut weeds and red rice again. Explanation of shapes, maps and diagrams (1) The long handle acts as the handle of the device. 2) The U-shaped chassis is the connection point for the moving rail of the moving part of the weed collector branches. 3) The weed collector branch is responsible for collecting weeds in one direction and on a straight line. 4) A box for storing cut grass. This box is responsible for collecting and storing cut grass and transporting it to the main boundary of the land. 5) Grass cutting blade: The cutting blades cut the collected grass by moving on their rails in the direction of the grass. 6) The brake lever is like a bicycle brake lever. The brake lever uses an uncoated wire to transfer the force of the hands to the weed-collecting branches. 7) Blade movement rail, a square-shaped rail that is responsible for the blade's movement path and maintaining its balance. 8) Coated wire: Coated wire is used to allow the uncoated wire inside it to move better and prevent the rings holding it from being cut. 9) Uncoated two-pronged wire, the uncoated wire, with its movement, transfers the force of the hands to the blade and the collecting branch. 10) Coated wire retaining rings. These rings hold uncoated and coated wires so that these wires are fixed in place and not in the path of other parts. 11) Spring: The spring is placed around a retaining rod and is used to return the sliding handle or the moving part of the grass collector branch. 12) Spring retaining rod, this rod, placed inside the spring, is responsible for holding and regular movement of the spring. 13) Sliding handle attached to the blade. This handle transfers the force of the hands to the grass cutting blade with the help of an uncoated wire. 14) The connecting clamp is the place where the uncoated wire connects to the grass cutting blade and the moving part of the weed collector branch. 15) Square rail, this part is for balancing the movement of the weed collecting branches. 16) The cylindrical rail holds the spring for returning the moving part of the weed collector branch. 17) The place where the brake handle wire passes, like the one connected to the weed collector branch 18) Passage of the wire connected to the weed cutting blade Additional description of the drawing: The rail is a square movement to balance the moving parts of the device, and the springs are used to return the moving part to its original position. The size of the rail of the sliding part (the handle responsible for moving the blade) is the size of the blade's movement path on its rail for cutting, plus the size of the rail of the part connected to the U-shaped chassis. In the case of the coated wire, its coating is fixed and only the wire inside it is movable, and this wire transfers the force of the hands to the blade or weed collector branch. The sliding handle is located inside the rod and the movement path of the sliding handle is located inside the spring of the holding rod. In addition, the last photo has been posted for the final part of the device because the components were not clear. A clear and precise statement of the advantages of the claimed invention over prior inventions. -The farmer, without entering the paddy field, performs the act of pruning weeds and red rice from the main border of the paddy field, which prevents some of the rice clusters from falling due to shaking (at harvest time, the rice clusters are yellow and ripe, and their connection is not very strong and they fall to the ground with a little shaking). 2- The operation of pruning weeds and red rice is carried out more quickly because weeds are spread in the form of bushes on the ground at the time of harvesting paddy (rice with husk). Considering that it is not possible to move quickly and the clusters are all stuck together, the operation is carried out with this device from the main boundary and the movement and speed restrictions are removed. 3_It reduces labor costs, reduces the number, and reduces the time required to perform pruning (each tree takes at least a week with the traditional method, but with a remote manual weeding device, this time is reduced.) 4_ The manual weeding machine has a box built into it that holds the cut weeds until the weeding and red rice weeding process is complete and the farmer dumps it on the main border of the paddy field. Weeds have seeds and lead to impurities. Description of at least one implementation method for implementing the invention A manual weeding device that is mechanically operated by hand, in which the farmer presses the handle of the branch collector to arrange the weeds in a straight line and connect the blades together, and then pulls the handle, like a tool, to move the weed-cutting blade on its rail, which is in line with the collected weeds, and the cutting action is performed, and the cut weeds fall into the surrounding box, and then the weeds are transferred to the main border (current). The second method is an electric weeding device that, by pressing the button, the weed bush is tied with a string, and by pressing the cutting button, the bunch is cut and placed in a box or moved on the rail of the bunch to the main border (future). Explicit mention of the industrial application of the invention This device is used in agriculture to eliminate weeds and red rice that are above the rice field surface without entering the rice field.

Claims

Claim What is claimed: Claim 1) An agricultural device consists of a weed collector, a weed cutter, and a box for collecting the cut grass. The force required to collect the weeds is transferred to the weed collector branches with the help of a brake-like handle through an uncoated wire. Then, by pulling the sliding handle (rolling) of the device, the force required for the cutting operation is transferred to the blade through the coated wire, causing the grass cutter blade to move on its rail, which causes the weeds to be cut, and the cut weeds fall into the box, and then the farmer empties the box onto the main boundary of the land. Different parts of the device: coated wire - spring - long rod (handle of the device) - sliding handle - brake handle - coated wire retaining rings - square and cylindrical moving rails - clamp connecting the uncoated wires to the blade and collector branches Claim 2) According to claim number one, the device has a rail for moving the weed cutting blade. This rail is designed in a square shape to better balance the blade, which balances the blade in its path of movement. Claim 3) According to claim number one, the device has a weed collecting section. This section consists of two branches that move towards each other on the X-axis, causing the weeds to be placed in a straight line in one direction. Claim 4) According to claim number three, the collecting device has two branches that move towards each other. The moving rail includes two square rails for moving on the track, which balances the branches and strengthens the connection of the two blade parts to each other. Claim 5) According to claims one and four, the weed-collecting branches return to their original position with the help of a sliding rail around which a spring is wound, with the help of spring force. Claim 6) According to claim number two, when the cutting operation is completed and the blade reaches the end of its square rail, it returns to its original position by a shock absorber attached to the back of the blade, which means that there is no need to manually adjust the blade after each cutting operation. Claim 7) According to claim number one, the device has a blade that is designed in two pieces for greater strength and freer placement of weeds between the branches, which causes both the connection of the two blades (locking together) and the force applied to the collecting branch to better hold the blades.
