Description

Technical Field

[0001] The present invention belongs to the technical field of transplanting hole drilling agricultural machinery, and in particular relates to an automatic hole drilling machine and method for transplanting. Background Art

[0002] At present, some crops are gradually being planted in the "well-cellar transplanting" method. The so-called "well-cellar transplanting" refers to making a well-cellar with a certain depth and aperture on the ridge to be planted with good soil moisture. Taking tobacco planting as an example, according to agronomic requirements, a well-cellar with a depth of 15-18cm, a diameter of 5-8cm and an appropriate amount of water needs to be made. According to the "Darcy's Law" of French hydraulician Darcy, as the external temperature and humidity change, the hydraulic gradient generated by the well-cellar causes the soil moisture in the well-cellar to evaporate or condense, thereby maintaining the relative stability of the temperature and humidity in the well-cellar, and providing a temperature, humidity and nutrition environment suitable for the growth of tobacco seedlings in the best transplanting season. It is conducive to timely early planting of tobacco seedlings, drought transplanting, rapid transplanting, centralized transplanting, high ridge deep planting, and promoting seedling recovery after planting and early growth and rapid development.

[0003] In the process of drilling holes in the soil and injecting water into the holes, the drilling machine is mainly carried by hand.

The bearing seat assembly 1-1-2 and the guide seat 1-2 are both fixed on the support assembly 1-5.

[0063] There is another sleeve 1-1-4 inside the bearing seat assembly 1-1-2. The sleeve 1-1-4 is connected to the transverse gear 1-1-5 through a flat key 1-1-9, and the sleeve 1-1-4 is assembled with the bearing 1-1-8 in the bearing seat assembly 1-1-2. The upper section of the sleeve 1-1-4 is locked by a lock nut 1-1-7 to ensure that the transverse gear 1-1-5 only rotates and does not move up and down.

[0069] The transmission shaft Ⅰ1-3-1 of the hole opening drive mechanism drives the transmission shaft Ⅲ1-4-7 to rotate via the sprocket chain mechanism, and then the crank turntable 1-4-2 is rotated to drive the upper rack slide 1-4-4 to move back and forth, so that the transverse gear 1-1-5 reciprocates, driving the hole drilling mechanism to reciprocate.

[0070] like Figure 8 As shown, the support assembly consists of a base 1-5-1, a square seat bearing 1-5-2 (model UELP205), a side slide bearing support 1-5-3, and an upper slide bearing support 1-5-4.

The wheelbase and ground clearance of the traveling assembly are adjustable.

[0073] The intermittent transmission system 3-3 can ensure that the whole machine is in a stopped state when the drilling mechanism completes the process of entering and exiting the soil for a drilling operation. After the drilling mechanism completely leaves the soil, the whole machine moves forward again to carry out the next drilling operation.
