Description
Technical Field
[0001] The utility model relates to the technical field of seedling machines, in particular to a seedling machine which can automatically backfill soil. Background Art
[0002] Seedling machines are mainly used as mechanical equipment to bury seedlings in the ground when various seedlings are planted in large quantities.
[0003] The method commonly adopted by existing seedling machines is that after a claw-like structure is inserted into the soil, it expands outward to release the seedlings, and then the claw-like structure is pulled out to transplant the seedlings in a pit-making manner. This type of transplanting structure has the problem that the opening and closing mechanism has poor durability and is easily damaged and stuck, causing subsequent failure. It has high requirements on the hardness of the soil for planting, and it is necessary to use a separate device to loosen the soil in advance before subsequent work can be carried out.
[0004] Some seedling machines use a grooving method, which is to facilitate the digging mechanism to dig long grooves in the soil, reserve soil on both sides of the groove mouth, and then use the passive baffle at the rear to backfill the soil. This equipment has poor control of soil splashing and accumulation position during excavation, and the passive baffle cannot backfill stably, which will cause poor uniformity of soil after backfilling, especially on soil surfaces that are not very flat. The bumps or ups and downs of the equipment will cause the bottom of the baffle to fit poorly to the ground, resulting in omissions in soil backfill. When this equipment has poor performance, it may even abandon the baffle and use manual backfilling at the rear, and the backfilling efficiency is relatively low.
[0005] In view of the above problems, a seedling machine for automatically backfilling soil is proposed. Utility Model Content

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-4 The utility model provides a technical solution: a seedling machine for automatically backfilling soil, comprising a main support 1, a seedling mechanism 2 is equipped at the top of the main support 1, and a backfilling mechanism 3 is equipped on the outer side of the bottom of the main support 1; the main support 1 comprises a fixing frame 12 for fixing the seedling mechanism 2, a telescopic rod 14 is hinged at the front end of the fixing frame 12, a flip beam 15 is hinged at the front end of the fixing frame 12, and a rotating loosening roller 16 is equipped at the front end of the flip beam 15; the seedling mechanism 2 comprises a guide groove 21, a rotating conveying screw 26 is equipped on the side wall of the guide groove 21, and the conveying screw 26 is installed obliquely downward; the backfilling mechanism 3 comprises a collecting groove 31, a guide groove 32 is welded at the rear end of the collecting groove 31, and a reflow groove 33 is welded at the end of the guide groove 32; the collecting groove 31 is tilted upward and fixed from front to back, the guide groove 32 and the reflow groove 33 are tilted downward and fixed from front to back, the connection point between the collecting groove 31 and the guide groove 32 is located at the highest position, and a conveyor belt is installed inside the collecting groove 31;
[0025] The utility model provides an automatic soil backfilling seedling machine with a main support 1, a seedling mechanism 2 and a backfilling mechanism 3. When in use, the main support 1 is connected to an external power tractor, and two different ways of front hanging or rear hanging can be selected to push or tow forward, and the tractor provides energy for driving. When in use, the loosening roller 16 digs and loosens the soil, so that the soil falls backward onto the conveyor belt at the top of the collecting trough 31 while being dug, and is transported backward by the conveyor belt to the inside of the guide groove 32, and downwardly falls from the notch of the return groove 33 under the influence of gravity to the groove before transmission for backfilling. The top view of the guide groove 32 is in the shape of a bracket and expands outward. The seedling mechanism 2 inside the expanded mouth puts seedlings into the groove dug by the loosening roller 16 at a fixed frequency, which effectively solves the problem that the existing soil backfilling method of the seedling machine generally adopts the backfilling by baffle plate or the backfilling in a separate backfilling process, which causes high requirements on ground flatness and low backfilling efficiency.
[0026] Specifically, a fixing frame 11 is fixedly mounted on the bottom end of the fixing frame 12, and a rotating matching walking wheel is mounted on the bottom end of the fixing frame 11. The walking wheel selects appropriate wheels according to the soil structure of the seedling position. Generally, lightweight rubber wheels are used, and the width of the tires is minimized. The spacing between the tires can be adjusted through the outer sliding rod and the top wire structure to achieve the purpose of adjusting the spacing and improve the walking adaptability between the ridges.
[0027] Specifically, a hanging frame 13 is welded to the front end of the fixed frame 12, and the turnover beam 15 is rotatably assembled on the front end of the hanging frame 13. The hanging frame 13 supports the front end and has a reinforcing rib structure.
[0028] Specifically, the outside of the loosening roller 16 is evenly distributed and welded with W-shaped digging rods, and the two tips of the digging rods extend in the direction of rotation. The loosening roller 16 is composed of an outer W-shaped digging knife-like digging rod. The blade cross-section of the digging rod is triangular, which is conducive to loosening the soil, and the curved W-shaped structure facilitates digging the soil from front to back and lifting it backwards to be intercepted by the collecting trough 31.
[0029] Specifically, an inclined groove 22 inclined rearward and downward is welded to the bottom end of the guide groove 21, an opening 24 is opened on the side wall of the inclined groove 22, bearing seats are welded at both ends of the opening 24, an output mechanism 25 composed of a rotating shaft and a motor is assembled inside the bearing seat, and a conveying screw 26 is welded to the outer wall of the output mechanism 25. The conveying screws 26 arranged symmetrically in opposite spirals can deliver the seedlings forward at a fixed speed through synchronous rotation, and the delivery spacing and the root size of the supported seedlings are determined by the pitch of the conveying screw 26.
[0030] Specifically, a feeding mechanism is installed at the top of the fixed frame 12. The feeding mechanism is generally a bucket-shaped structure with a spiral downward, similar to a vibrating plate. The existing long seedling trough can also be used to manually release the seedlings. The seedlings only need to enter the interior of the conveying spiral in order.
[0031] Specifically, a seedling dropping tube 23 is vertically slidably assembled at the end of the guide groove 21, and the seedling dropping tube 23 is fixed to the guide groove 21 by bolts. The seedling dropping tube 23 is used to limit the falling direction of the seedlings and assist in straightening the seedlings to ensure the stability of the equipment operation.
[0032] Specifically, the top of the collecting trough 31 is rotatably equipped with a conveyor belt that runs tilted backward and upward. The conveyor belt is preferably driven by an electric motor. When rotating, the top rubber conveyor belt will throw the loose soil backward into the inside of the guide trough 32. After being tilted downward and guided, it will automatically be thrown into the inside of the excavated trench from the reflux trough 33 and the opening at the tail of the reflux trough 33.
[0033] The extension and retraction of the telescopic rod 14 can drive the loosening roller 16 and the turning beam 15 to turn around the front end of the lifting frame 13, so as to realize the action of lifting or lowering the loosening roller 16. The loosening roller 16 has three main working modes, one is the normal excavation depth, one is the grooving depth lower than the normal excavation depth, and the other is the upward recovery height that does not affect the transportation and walking, which is convenient for the normal use of the loosening roller 16.
[0034] In addition to the tires with adjustable spacing installed on the outer bottom of the fixing frame 11, the working height between the fixing frame 12 and the tire can also be driven by an electric or other powered lifting rod installed at the connection position to adjust the spacing between the bottom of the backfill mechanism 3 and the ground.
[0035] All structural power of the utility model as a whole is preferably electrically driven, and some one-way displacement components are preferably hydraulically or pneumatically driven, which means that the power energy source is provided by the tractor.
[0036] Specifically, the height difference between the bottom of the seedling dropping tube 23 and the ground is not higher than the height of the seedlings. After the seedlings fall to the planting position, the bottom of the backfill mechanism 3 and the seedling dropping tube 23 are not higher than the seedlings, so as to avoid scraping the seedlings.
[0037] The reflow trough 33 has two structures. One is shown in the figure and is used for planting buried seedlings of tubers such as potatoes and sweet potatoes. The rear end opening of the reflow trough 33 is located in the middle position, which is mainly used to completely cover the seedlings. The other is similar to the structure of the collecting trough 31, which is a structure with the opening disconnected in the middle and bent inward, that is, the opening position of the reflow trough 33 in the figure is completely disconnected. The purpose is to evenly release soil from both sides of the seedlings to avoid planting seedlings of eggplants, green onions, etc. whose stems and leaves need to remain on the surface.
[0038] Specifically, the outside of the flip beam 15 is a thin shell structure, and the inside of the thin shell structure is equipped with a power mechanism and a transmission mechanism to provide rotational power for the loosening roller 16. A motor is installed inside the outer shell similar to a round roller at the top of the flip beam 15. The motor outputs power to both sides through a reducer and an axle. There is also an extended shaft structure on the outside of the loosening roller 16. Pulleys and belts are installed on the outside of the axle and the extended shaft structure for normal excavation operation. When the loosening roller 16 exceeds the excavation carrying capacity and is stuck, the belt can avoid damage to the motor drive and transmission structure by slipping and releasing force.
