Description

A uniform speed and width narrow pitch caster

Technical field

[0001] The present invention relates to a rice transplanter, and more particularly to a wide and narrow row transplanter.

Background technique

[0002] Traditional rice cultivation generally adopts the method of equal spacing and equal spacing, but this method of incorporation is bound to have a problem of shading between plants and plants, and the utilization of nutrients in the soil is uneven. Causes a lot of waste. At present, wide and narrow row transplanting methods have been widely used, and it is a high-yield rice cultivation technique cultivated by narrow row spacing and wide row spacing. The cultivation method can not only ensure the reasonable number of holes per unit area, but also has the advantages of reasonable distribution of plant population, good ventilation and light transmission performance, and high photosynthesis rate. Therefore, the high yield level is one of the cultivation methods frequently selected for high-yield research. At the same time, due to the enhanced ventilation and light transmission, the humidity between the rice plants is reduced, which can reduce the pests and diseases to a certain extent, and finally achieve the goal of high yield and income. At present, a variety of wide and narrow row transplanters have been designed to meet the above agronomic requirements. However, due to various geographical conditions, such as the orientation of the acre, the lighting conditions, etc., we need to adopt a wide and narrow plant spacing method. Corresponding ventilation and light transmission conditions are obtained. Therefore, a wide and narrow plant spacing transplanter is needed, that is, the inserted seedlings are alternately arranged in a wide and narrow walking direction of the rice transplanter. For example, the Chinese patent of CN1 04663086A discloses a planting mechanism for a new type of wide and narrow plant spacing transplanter, including a plurality of horizontally arranged planting boxes, each of which has a left and right turntable, each Each of the two sides of the rotary box is respectively provided with a planting arm, and the planting mechanism is provided with a horizontally arranged main input shaft, the main input shaft is connected with each planting box, and is rotated by a non-uniform output. The box is connected to the power input

The shifting transmission box comprises one or several shifting gear pairs that can be switched, and each shifting gear pair is composed of a driving gear and a driven gear, and each driving gear is connected to the power input end through a corresponding transmission mechanism, each driven The gear is coupled to the main input shaft by a corresponding transmission mechanism. The technical scheme realizes the purpose of wide and narrow plant spacing transplanting, but due to its complicated structure, the power output end is a process of changing the rotational speed, so the impact on the mechanism will be relatively large, and the combination of these factors makes the transplanting of the transplanting machine The failure rate of the mechanism is high and the stability of operation is relatively low.

technical problem Problem solution

Technical solution

[0003] The present invention mainly solves the technical problems existing in the prior art, such as complicated structure, high failure rate, poor operational stability, and the like, and provides a uniform speed, narrow failure rate, and good stability.

[0004] The above technical problem of the present invention is mainly solved by the following technical solutions: a uniform speed and narrow pitch caster, including a frame, a seedling and a planting mechanism, the planting mechanism is provided with a rotary box, a rotary box The two ends are respectively provided with a planting arm, and each of the planting arms is respectively provided with a plugging claw, and the seedling stage is connected with the seedling driving mechanism, and the seedling driving mechanism is provided with a screw shaft, the screw shaft and the screw shaft The power end is connected, the seedling stage is provided with a threaded guide block, and the lead end of the thread guide block is adapted to the thread groove of the screw shaft, and the thread groove of the screw shaft is long distance guide The slot and the macro guide are formed in series with each other, one long guide groove is a lead, one micro guide groove is a half lead, and the guide end of the thread guide block is from a long guide groove During the process of moving from one end to the other end, the insertion claw passes through the picking position twice, and obtains the seedling, and the guiding end of the threaded guiding block moves from one end of one macro guiding groove to the other end. The insertion claw of the planting mechanism passes through Take seedling position, but can not get the seedlings. By using the invention to perform the insertion, the rotation of the screw shaft drives the movement of the seedling table with the thread guide block. Since the screw shaft is formed by the long distance guide groove and the macro guide groove being separated from each other, the movement of the seedling stage is inevitable. During the movement, during the uniform rotation of the rotary box, the two rotary boxes in front and rear of the rotary box are evenly spaced, and the spacing between the turns is taken, but because the moving speed of the seedlings alternates, when the thread guides The block corresponds to the long guide groove, that is, the seedling table moves quickly, the insertion claw passes through the clamp position twice, and the seedling is taken, and when the thread guide block corresponds to the micro guide groove, the seedling table moves slowly, and the claw is inserted. Only one pass through the position, and because the displacement of the seedlings is too short in the process, the transplanting claws cannot take the seedlings. After the insertion claw can not be taken, the insertion claw will be inserted into the empty insertion, and then the insertion will continue. After the end of the transplanting machine, the process of alternate operation of one empty insertion and two actual insertions forms a method of transplanting wide and narrow plant spacing.

[0005] Preferably, the long distance guiding groove corresponds to 1.6-1.8 seedling positions on the seedling stage, and the macro guiding groove corresponds to 0.2-0.1 seeding positions on the seedling stage. The seedling position refers to the theoretical length of the single seedlings on the carpet seedlings, that is, the total width of the carpet seedlings divided by the number of seedlings in the width, and the seedlings and the plants on the carpet seedlings are separated by a groove. Therefore, the joint between the strain and the strain of the seedling is a relatively weak part. According to the present technology The design of the scheme, when the claws are taken, the theory should take out the seedlings and the parts swept by the transplanting claws are 0.1 to 0.2 seedlings, but because the connection between the plants and the plants is relatively fragile, In most cases, the whole plant's seedlings can be removed, and when the transplanting claws should be inserted through the seedling position, the position of the seedlings before the seedlings is only 0.1-0.2. The seedling position is just the seedling position that the seedling platform driven by the long-distance guide channel has not completed. Therefore, the transplanting claw and the seedling do not interfere here.

Embodiments of the invention

The technical solutions of the present invention will be further described in detail below by way of embodiments and with reference to the accompanying drawings.

[0010] Embodiments: As shown in FIG. 1 and 2, the present invention is a uniform rotation speed wide and narrow plant spacing transplanter, including a frame, a seedling table 1 and a planting mechanism, and the planting mechanism is provided with a rotary box 2, and the rotary box 2 The two ends are respectively provided with a planting arm 3, and each of the planting arms is respectively provided with a plugging claw 4, and the seedling stage is connected with the seedling driving mechanism, and the seedling driving mechanism is provided with a screw shaft 6, The screw shaft 6 is connected to the power end, and the seedling stage is provided with a threaded guide block 7, the guiding end of the threaded guide block is adapted to be in the thread groove of the screw shaft, and the thread groove of the screw shaft is The long distance guiding groove 61 and the macro guiding groove 62 are formed in series with each other, and the long distance guiding groove corresponds to 1.6-1.8 seedling positions on the seedling stage, and the macro guiding groove corresponds to the seedling stage. 0.2-0.1 take seedlings. The seedling position refers to the theoretical length of the single seedling on the carpet seedling, that is, the total width of the carpet seedling divided by the seedlings of the width. Number of strains. During the process of moving the leading end of the threaded guide block from one end of the long distance guide groove to the other end, the insertion claw passes through the picking position 5 twice, and obtains the seedling, and the guiding of the threaded guide block During the process of moving from one end of one of the macro guide grooves to the other end, the insertion claw of the planting mechanism passes through the picking position once, but the seedling cannot be obtained.

[0011] In the invention, the frame is moved at a constant speed by the wheel, the screw shaft rotates at a constant speed, and the rotation of the screw shaft drives the movement of the seed guide with the thread guide block, since the screw shaft is composed of a long distance guide groove and a micro The distance between the guide channels and the guide grooves is alternately connected, so the movement of the seedlings must be alternated one by one. During the movement, during the uniform rotation of the rotary box, the two rotary boxes in the front and rear of the rotary box are even and evenly spaced. By taking the seedling position, but because the speed of the seedlings moves alternately, when the threaded guide block corresponds to the long guide groove, that is, the seedling table moves quickly, the insertion claw passes twice to take the position, and the seedling is taken, when the thread guide block Corresponding to the micro-guide groove, that is, the seedlings move slowly, the insertion claw only passes through the position, and because the displacement of the seedlings is too short in the process, the seedlings cannot be taken. After the insertion claw can not be taken, the insertion claw will be inserted into the empty insertion, and then the two insertions will be continued. After the insertion machine is formed, the process of alternate operation of one empty insertion and two actual insertions forms a method of transplanting wide and narrow plant spacing.

[0012] Therefore, the present invention has the characteristics of simple structure, low failure rate, and good stability.
