Description

Technical Field

[0001] This utility model belongs to the field of agricultural planting technology, specifically relating to a digging machine for planting Astragalus membranaceus. Background Technology

[0002] Astragalus is a common Chinese medicinal herb. Currently, in order to meet market demand and protect the population of wild astragalus, artificial cultivation has become the main production method. To improve the quality of astragalus, seedlings are usually cultivated first and then transferred to the wild for planting. To ensure the survival rate, holes are dug in the ground before planting. Currently, to reduce labor costs, agricultural machinery is often used for digging holes, which uses external equipment such as motors or engines to drive a drilling rod to dig holes. However, the depth of the holes dug by such equipment is mostly controlled by the operator. On the one hand, it is difficult to achieve standardized planting, which affects the survival rate. On the other hand, it places higher demands on the operator and is difficult to meet the needs of convenient and efficient planting. Utility Model Content

[0003] The purpose of this invention is to provide a planting hole-digging machine for Astragalus membranaceus, which solves the problems mentioned in the background art.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A hole-digging machine for planting Astragalus membranaceus includes a machine head and a control panel. The machine head is equipped with a transmission device and a hole-digging mechanism at its lower end.

[0006] The hole-digging mechanism includes a drilling rod, an outer sleeve, and a limiting component. The drilling rod is rotatably mounted at the lower end of the machine head and is connected to the transmission device. The outer sleeve is concentrically distributed with the drilling rod and is fixedly connected to the lower end of the machine body. The limiting component is located between the machine head and the outer sleeve.

[0007] The limiting component includes a limiter and a sliding foot pedal, both of which are slidably mounted on the outer sleeve, with the limiter located on the upper side of the sliding foot pedal.

[0008] The limiter includes a first slip ring, a limit clamp, a pull rod, a spring, and a tail handle. The outer sleeve has a vertical groove on its side, and a rack is provided in the vertical groove. The first slip ring has an installation opening that matches the vertical groove. The limit clamp is slidably disposed in the installation opening and corresponds to and matches the rack. The pull rod is connected to the other end of the limit clamp and slides through the side of the first slip ring in the installation opening. The tail handle is connected to the other end of the pull rod. The spring is sleeved on the pull rod and located between the limit clamp and the installation opening.

[0009] The limiting clamp is a wedge that matches the rack, with the openings of adjacent teeth in the rack facing downwards and the openings of the wedge in the limiting clamp facing upwards.

[0010] The sliding foot pedal includes a second slip ring and a pedal rod. The second slip ring is slidably connected to the outer sleeve, and the pedal rod is connected to the second slip ring and extends downward.

[0011] The outer sleeve has a guide groove on its side, and the first slip ring and the second slip ring are slidably connected to the guide groove by a slider.

[0012] This application has at least the following advantages compared to the prior art:

[0013] This application, through the setting of the pit-digging mechanism, allows for flexible control of the pit depth during Astragalus planting, based on the needs of the planting environment and the growth status of the seedlings. This standardizes planting practices, facilitates planting, and makes early pit-digging preparation more efficient. The sliding foot pedal in the limiting component can both calibrate the pit-digging depth and provide support for the entire device, reducing physical exertion and difficulty during pit digging and improving the stability of the device during pit digging.

[0019] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-3 As shown, an Astragalus planting hole-digging machine includes a machine head 1 and a control panel. The machine head 1 is equipped with a transmission device, and the lower end of the machine head 1 is equipped with a hole-digging mechanism.

[0021] The hole-digging mechanism includes a hole-drilling rod 11, an outer sleeve 2, and a limiting component. The hole-drilling rod 11 is rotatably located at the lower end of the machine head 1 and is connected to the transmission device. The outer sleeve 2 is concentrically distributed with the hole-drilling rod 11 and is fixedly connected to the lower end of the machine body. The limiting component is located between the machine head 1 and the outer sleeve 2.

[0022] The limiting assembly includes a limiter and a sliding foot pedal. Both the limiter and the sliding foot pedal are slidably mounted on the outer sleeve 2, with the limiter located on the upper side of the sliding foot pedal.

[0023] When planting Astragalus membranaceus, the operator moves the device by holding the handle on the machine head 1. The control panel is located on the handle for convenient and quick opening and closing. The transmission uses an electric motor or gasoline engine to drive the drilling rod 11. Depending on the size of the Astragalus membranaceus seedlings, the depth of the hole to be dug can be limited by the limiting component. When limiting, the position of the limiter on the outer tube 2 is adjusted until it is appropriate. The depth of the hole is the length of the distance the sliding foot moves from bottom to top on the outer tube 2 to the limiter. Therefore, the corresponding height can be marked on the outer tube 2 for easy adjustment and observation. When drilling, the transmission drives the drilling rod 11 to drill a hole in the ground and gradually go deeper. At this time, since the sliding foot is kept on the ground, and the drilling rod 11 and the machine head 1 move downward as a whole, the sliding foot will move upward relative to the outer tube 2 until the sliding foot abuts against the limiter. At this time, the drilling rod 11 can no longer move downward, thus limiting the depth of the hole. This can meet the fixed planting depth when planting Astragalus membranaceus and meet the planting needs of Astragalus membranaceus at different growth stages.

[0024] The limiter includes a first slip ring 3, a limit clamp 31, a pull rod 32, a spring 33, and a tail handle 34. The outer sleeve 2 has a vertical groove 35 on its side, and a rack 36 is provided in the vertical groove 35. The first slip ring 3 has an installation port 37 that matches the vertical groove 35. The limit clamp 31 is slidably disposed in the installation port 37 and corresponds to and matches the rack 36. The pull rod 32 is connected to the other end of the limit clamp 31 and slides through the side of the first slip ring 3 in the installation port 37. The tail handle 34 is connected to the other end of the pull rod 32. The spring 33 is sleeved on the pull rod 32 and is located between the limit clamp 31 and the installation port 37.

[0025] The limiting head 31 is a wedge that matches the rack 36. The openings of the adjacent teeth in the rack 36 face downwards, while the openings of the wedges in the limiting head 31 face upwards.

[0026] When adjusting the drilling depth, simply pull the tail lever 34 to cause the pull rod 32 to pull the limiting chuck 31 away from the rack 36. At this time, the first slip ring 3 can be slid up and down to adjust the drilling depth. After adjustment, release the tail lever 34 and fine-tune the first slip ring 3 to ensure that the limiting chuck 31 can be stably engaged with the rack 36. Since the adjacent tooth blocks of the rack 36 have downward openings, the opening orientation of the limiting chuck 31 ensures that the first slip ring 3 is not affected by upward pushing, causing the limiting chuck 31 to move automatically past the rack 36. In some scenarios, due to the engagement orientation of the rack 36 and the limiting chuck 31, the first slip ring 3 may be affected by external factors and move automatically downwards. Therefore, the rack 36 and the limiting chuck 31 can be replaced with a rectangular or conical structure to meet the requirement of absolute stability in vertical movement while limiting.

[0027] The sliding pedal includes a second slip ring 4 and a pedal rod 41. The second slip ring 4 is slidably connected to the outer sleeve 2, and the pedal rod 41 is connected to the second slip ring 4 and extends downward.

[0028] When drilling, the operator steps on the foot bar 41 to keep it in contact with the ground, and the second slip ring 4 is connected to the foot bar 41 to form a relatively fixed height. At this time, due to the change in the height of the drilling pit, the gap between the second slip ring 4 and the first slip ring 3 will be reduced, thereby controlling the drilling depth.

[0029] The outer tube 2 has a guide groove 5 on its side, and the first slip ring 3 and the second slip ring 4 are slidably connected to the guide groove 5 through a slider; this can improve the sliding stability of the first slip ring 3 and the second slip ring 4.

[0030] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
