Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cistanche deserticola planting, especially to a soil covering device for cistanche deserticola planting. BACKGROUND

[0002] Cistanche deserticola is a parasitic plant that parasitizes the roots of desert trees, absorbs nutrients and water from the host tree, and is known as "desert ginseng" for its high medicinal value. It is a traditional Chinese precious medicinal material. Cistanche deserticola also has good economic value, making it possible to generate economic benefits while greening the desert.

[0003] During the planting process of cistanche deserticola, soil covering is required, which is a key step in artificial cultivation. The main purpose of soil covering is to simulate the natural sand burial environment, protect the young buds from wind and sand, strong light or extreme temperature damage by covering part of the stem, maintain soil moisture and stabilize root temperature and humidity, promote the establishment of parasitic relationship and the accumulation of medicinal components (such as phenylethanoid glycosides and polysaccharides), and adjust the soil covering thickness according to the soil type and climate. If the soil covering is too deep, it will inhibit germination, and if it is too shallow, it will not be able to maintain moisture and prevent wind.

[0004] In the prior art, a soil covering device for cistanche deserticola inoculation is disclosed in Chinese Utility Model Patent No. CN215223017U. The device can adjust the turning angle of the soil covering plate by continuously pulling the steel wire while holding the control panel with one hand, thereby achieving backfilling of the soil on both sides of the tunnel and avoiding the phenomenon of soil backfilling omission or uneven backfilling at a fixed angle. However, the soil covering device is not convenient for adjusting the soil covering thickness according to the soil type and climate. If the soil covering is too deep, it will inhibit the germination of cistanche deserticola, and if it is too shallow, it will not be able to maintain moisture and prevent wind.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: A soil covering device for planting Cistanche deserticola, such as... Figures 1-3 As shown, the device includes a base frame 1, with a traction rod 14 hinged to the front end of the base frame 1. A U-shaped rod 11 is fixedly installed at the rear bottom of the base frame 1. Two rollers 12 spaced apart are rotatably installed at the bottom end of the U-shaped rod 11. A downwardly extending support rod 13 is fixedly installed at the front bottom of the base frame 1. Rollers 12 are rotatably installed at the bottom end of the support rod 13. The three rollers 12 are arranged in a triangular pattern in space to form a stable mechanical structure with three-point support. This can evenly distribute the load of the base frame 1 and the device, reduce single-point pressure, and prevent overturning or sinking in soft sand or uneven terrain, thereby improving the overall stability.

[0023] The rear end of the chassis 1 is fixedly provided with a rod member 3 extending in the left-right direction, both ends of the rod member 3 extend to the left and right of the chassis 1 and are provided with earth covering plates 2, the left and right two earth covering plates 2 are symmetrically arranged, and the earth covering plates 2 are used to scrape the sand soil generated in the process of planting Cistanche to the base of the Cistanche stem for covering; a lifting adjusting mechanism 4 is arranged between the rod member 3 and the earth covering plate 2, the lifting adjusting mechanism 4 is used to adjust the height of the earth covering plate 2, and then the earth covering thickness of the Cistanche is adjusted according to the soil type and climate, so as to avoid that the Cistanche is inhibited from germination due to too deep covering, and the Cistanche cannot be kept moist and windproof due to too shallow covering. Specifically, the lifting adjusting mechanism 4 comprises sleeves 41 fixedly arranged at both ends of the rod member 3 and extending upward, a lifting rod 42 capable of sliding up and down is arranged in the sleeve 41, the bottom end of the lifting rod 42 penetrates out of the sleeve 41 and is fixedly provided with the earth covering plate 2, the sleeve 41 is a circular sleeve, a plurality of groups of first insertion holes 43 are arranged in the sleeve 41 in the radial direction of the sleeve 41, a second insertion hole 44 corresponding to any one group of the first insertion holes 43 is arranged on the lifting rod 42, the position of the lifting rod 42 and the earth covering plate 2 can be adjusted in height by adjusting the corresponding position of the second insertion hole 44 and different first insertion holes 43; a positioning pin 45 is arranged in the second insertion hole 44 and the corresponding group of first insertion holes 43, and the positioning pin 45 is used to fix the adjusted lifting rod 42 on the sleeve 41. For those skilled in the art, the positioning pin 45 is a known technology, and therefore will not be described in detail.

[0024] When the second insertion hole 44 corresponds to any one group of the first insertion holes 43, the left and right two earth covering plates 2 are arranged obliquely from front to back and from middle to both sides, which can disperse the longitudinal resistance when the earth covering plate 2 scrapes the soil, reduce the resistance when the device moves, guide the sand soil to flow from the middle to the both sides towards the base of the Cistanche stem, avoid local soil accumulation or missing coverage, and ensure the uniformity of the coverage thickness.

[0025] The end of the earth covering plate 2 close to the chassis 1 is fixedly provided with a baffle 5 extending forward, which can prevent the sand soil from entering the lower part of the chassis 1 and affecting the normal movement of the device.

[0026] The rod 3 includes a fixed rod 31 and two sliding rods 32 that slide through the fixed rod 31. The ends of the sliding rods 32 can pass through the fixed rod 31 and connect to the lifting and adjusting mechanism 4. The fixed rod 31 has multiple first through holes 33 that extend in the left and right direction and are open at the top and bottom. The sliding rods 32 have second through holes 34 that are open at the top and bottom and can correspond to any of the first through holes 33. By adjusting the position of the second through holes 34 corresponding to different first through holes 33, the position of the sliding rods 32 in the fixed rod 31 can be adjusted, thereby changing the left and right position of the lifting and adjusting mechanism 4 and the soil covering plate 2. This allows the spacing between the two soil covering plates 2 to be adjusted left and right according to the planting position of two adjacent rows of Cistanche deserticola, so as to accommodate Cistanche deserticola planting with different row spacing and ensure that the soil covering range accurately matches the planting row position. Bolts 35 are inserted in both the second through hole 34 and the corresponding first through hole 33. The bolts 35 are used to fix the adjusted sliding rods 32 to the fixed rod 31.

[0027] The base frame 1 is a H-shaped frame structure. A counterweight can be detached from the top of the base frame 1. The counterweight is used to increase the overall weight of the base frame 1 according to the hardness of the sand and the resistance of the soil cover, thereby improving the stability of the device during movement. The counterweight is a sandbag, which can be directly used in the sand. At the same time, the weight of the counterweight can be flexibly adjusted. For those skilled in the art, the counterweight is a well-known technology and is not shown in the figure, so it will not be described in detail.

[0028] Multiple reinforcing rods 6 are fixedly installed inside the base frame 1, spaced apart on the left and right. The counterweight is located above the reinforcing rods 6. The reinforcing rods 6 can form a grid plane on the top of the base frame 1 to support the counterweight. At the same time, the reinforcing rods 6 can enhance the stability of the overall structure of the base frame 1.

[0029] Working principle: When carrying out the soil covering operation, the traction rod 14 is pulled by manpower or tractor equipment to move the device body. At the same time, the soil covering plate 2 tilts from front to back to scrape the surface sand, which is blocked and diverted by the baffle 5 and directionally covered to the base of the Cistanche deserticola stem.

[0030] When adjusting the height of the soil covering plate 2, pull out the positioning pin 45, move the lifting rod 42 up and down so that the second insertion hole 44 is aligned with the first insertion hole 43 on the sleeve 41, and then reinsert the positioning pin 45 into the first insertion hole 43 and the second insertion hole 44 to fix it, thus completing the adjustment of the height of the soil covering plate 2.

[0031] When adjusting the spacing between the two covering plates 2 according to the row spacing of Cistanche deserticola, loosen the bolt 35, slide the sliding rod 32 in the position of the fixed rod 31, so that the second through hole 34 is aligned with the first through hole 33, adjust the left and right spacing of the covering plates 2, and then reinsert the bolt 35 into the second through hole 34 and the first through hole 33 for fixing, thereby matching the planting row spacing of Cistanche deserticola.

[0032] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the application can be implemented in other particular forms without departing from the spirit or essential characteristics of the application. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No feature of the application is considered critical unless it is expressly stated in the claims.
