Description

Technical Field

[0001] The utility model relates to the field of sesame sowing equipment, in particular to a rotary tillage bin of a hand-wheel opening and closing sesame sowing machine. Background Art

[0002] Sesame seeds are small and are primarily sown through broadcasting and drill sowing. Broadcasting, which spreads the seeds evenly across the soil surface, offers the advantages of simplicity and speed, but has the disadvantages of requiring a large seed load, shallow soil cover, uneven seedling emergence, difficulty managing the plant, and high labor input. Drill sowing, which uses a sesame seeder to plant seeds at a specific row spacing and depth, facilitates ventilation and light transmission, is easy to manage, and requires fewer seeds. With increasing mechanization, sesame seeders are now integrating multiple functions, including rotary tillage, fertilization, sowing, and soil covering, resulting in high-quality sowing and saving time and effort.

[0003] A sesame planter with rotary tillage function tills and loosens the soil through a rotary tillage tooth assembly in a rotary tillage bin. During the rotary tillage operation, stubble from the previous season's crops will remain in the field. If the soil is not dry enough and the stubble is wet, the soil and stubble will often be rotated by the rotary tillage tooth assembly into the corners inside the rotary tillage bin, where they will stick together and accumulate, requiring frequent cleaning. Current rotary tillage bins are usually one-piece skeleton shell structures, so when cleaning, the rotary tillage trough needs to be lifted up and cleaned from below. The cleaning process is very troublesome, time-consuming, labor-intensive, and has certain safety hazards. Utility Model Content

[0023] Example 1, see attached Figure 1 、 7 A hand wheel 161 opening and closing type sesame seeding machine rotary tillage bin, the rotary tillage bin includes a square tube beam A 11 and a square tube beam B 12 arranged side by side, a support end plate 13 is welded and fixed between the end faces of the square tube beam A and the square tube beam B, a protective baffle is provided between the two support end plates and the outer side faces of the square tube beam B 12, a rotary tillage tooth assembly 18 is rotatably mounted between the lower ends of the two support end plates 13, a reducer mounting plate 14 is provided between the middle parts of the square tube beam A 11 and the square tube beam B 12, the reducer mounting plate The mounting plate is used to install a reducer to drive the rotary tillage tooth assembly 18 to rotate. An arc-shaped cover plate 15 is hinged on the square tube beam A 11 between the reducer mounting plate 14 and the end plate through a hinge 151. A handle can be installed in the middle of the arc-shaped cover plate to open or close the arc-shaped cover plate. The arc-shaped cover plates 15 at both ends and the reducer mounting plate 14 in the middle close the upper end of the rotary tillage bin to form a closed rotary tillage bin structure. A locking mechanism 16 is provided between the arc-shaped cover plate 15 and the square tube beam B 12.

[0024] The edge portion of the arc-shaped cover plate 15 in the longitudinal direction is provided with an L-shaped reinforcement fold 154, and a reinforcement end plate 153 is provided between the two L-shaped reinforcement folds and the end face of the arc-shaped cover plate 15. The L-shaped reinforcement fold and the reinforcement end plate can reinforce the arc-shaped cover plate at the surrounding edge portion, improve its anti-deformation strength, and ensure the stability of the arc-shaped cover plate 15 during rotary tillage operations.

[0025] Both ends of the speed reducer mounting plate 14 are provided with docking plates 17, and a hanging piece 171 is fixedly connected to the docking plate by bolts. The hanging piece is used to connect the rotary tillage bin with the traction equipment.

[0026] During the operation of the rotary tillage bin of this embodiment, when soil and stubble stems adhere to and accumulate at the corners inside the rotary tillage bin, the locking mechanism 16 is operated to release the lock of the arc cover 15, and then the two arc cover plates 15 are opened. After opening, the soil and stubble stems lose their attachment and partially fall off automatically. Then the remaining parts are cleaned from the top, and then the arc cover plates 15 are closed and locked. This process does not require the rotary tillage bin to be lifted for cleaning, which has the advantages of saving time and effort and high operational safety.

[0027] Example 2, see attached Figure 2-6 On the basis of the first embodiment, this embodiment sets the locking mechanism 16 as follows: including a hand wheel 161, a sliding rod 162 and a push spring 163. The side edge of the arc-shaped cover plate 15 is provided with a guide slide hole. The sliding rod is fixedly connected to the center of the hand wheel 161 to form an integrated structure. The lower end of the sliding rod 162 is vertically provided with a cross bar 164. The cross bar is the locking head of the mechanism. A V-shaped plate 165 is provided on the inner side of the square tube beam B 12. The V-shaped plate opening is arranged downward. The V-shaped plate 165 is fixedly connected to the inner side of the square tube beam B 12 through a vertical plate 168. A horizontal long hole 166 is provided in the middle of the V-shaped plate. The cross bar 164 is inserted horizontally from the cross bar 164. The long hole 166 extends into the V-shaped plate 165, and the push spring 163 is mounted on the sliding rod 162 between the handwheel 161 and the surface of the arc-shaped cover plate 15. The sliding rod can be driven to move along the guide slide hole by the spring. The length of the transverse long hole 166 is greater than the length of the cross bar 164, and the width of the transverse long hole 166 is less than the length of the cross bar 164. This size design makes the cross bar 164 stuck in the V-shaped plate 165 and will not slip out of the transverse long hole 166, thereby achieving locking. When the cross bar 164 rotates in the same direction as the length of the transverse long hole 166, it can slip out of the transverse long hole 166 and release the lock.

[0028] When the locking mechanism 16 is in use, the hand wheel 161 is pressed downward by hand, the push spring 163 is compressed, the sliding rod 162 slides downward along the guide slide hole, and the cross bar 164 at the lower end disengages from the V-shaped plate 165. Then the hand wheel is rotated, and the sliding rod 162 and the cross bar at the lower end rotate accordingly to correspond to the horizontal long hole 166. The hand wheel 161 is released, and the elastic force of the push spring 163 drives the sliding rod 162 to slide upward, and the cross bar 164 disengages from the horizontal long hole 166 to achieve unlocking.

[0029] A flat plate 152 is set at the edge of the arc-shaped cover plate 15, and a guide sliding hole is set on the flat plate. The lower end of the push spring 163 is supported on the surface of the flat plate. The flat plate 152 is used to provide horizontal support for the spring to ensure the pushing effect of the push spring 163, and can increase the sliding stroke of the sliding rod 162, making unlocking more convenient.

[0030] A limiting boss 167 is provided at the center of the handwheel 161, and the upper end of the push spring 163 is sleeved on the limiting boss. The limiting boss 167 is used to improve the stability of the push spring 163 sleeved on the sliding rod 162 to avoid deformation and dislocation of the spring.
