DETAILED DESCRIPTION
[0020] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.
[0021] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.
[0022] Example 1
[0023] like Figure 1-Figure 2 As shown, in this embodiment, a shovel for soil digging is provided, including a shovel body 1 and a handle 2, the shovel body 1 and the handle 2 are connected, and also includes a storage box 3, a pressing plate 6 and a bottom plate 8, the storage box 3 is arranged on the front wall of the handle 2, the upper rotating shaft 4 passes through the top wall and the bottom wall of the storage box 3, the upper rotating shaft 4 is rotatably arranged on the storage box 3, a rectangular cavity is arranged in the upper rotating shaft 4, and the bottom end of the rectangular cavity is open,
[0024] The pressing plate 6 is located above the accommodating box 3, and is connected to the pressing plate 6 with a rack 5 and a sliding column 7, which both penetrate the top wall and the bottom wall of the accommodating box 3, and the bottom ends of the sliding column 7 and the rack 5 are connected to the bottom plate 8, and a lower rotating shaft 9 is rotatably arranged on the bottom plate 8, and the top end of the lower rotating shaft 9 is connected to a rectangular column 10, and the rectangular column 10 enters the rectangular cavity, and a through hole 14 is opened on the pressing plate 6, and the upper rotating shaft 4 can pass through the through hole 14, and the bottom end of the lower rotating shaft 9 is connected to a crushing head 15,
[0025] The first bevel gear 11 is sleeved on the upper rotating shaft 4. A rotating shaft is rotatably arranged in the receiving box 3. The second bevel gear 12 and the gear 13 are sleeved on the rotating shaft. The rack 5 is meshed with the gear 13. The rack 5 moves downward to drive the gear 13 to rotate, thereby driving the rotating shaft and the second bevel gear 12 to rotate in the vertical plane. The second bevel gear 12 drives the first bevel gear 11 to rotate in the horizontal plane, thereby driving the upper rotating shaft 4 to rotate in the horizontal plane.
[0026] A limiting mechanism is provided on the handle 2 , and the limiting mechanism can fix the pressing plate 6 on the handle 2 .
[0027] The specific working principle is as follows: in the initial state, the limiting mechanism fixes the pressing plate 6, and the crushing head 15 is located above the shovel body 1. In the process of digging soil, when encountering hard soil, the shovel is placed vertically, the limiting mechanism is removed, and the pressing plate 6 is pressed downward. The pressing plate 6 drives the rack 5 and the sliding column 7 to move downward, and then drives the bottom plate 8 to move downward. The bottom plate 8 drives the crushing head 15 to move downward. At the same time, the rack 5 drives the gear 13 to rotate, and the gear 13 drives the rotating shaft and the second bevel gear 12 to rotate in the vertical plane. The second bevel gear 12 drives the first bevel gear 1 1 rotates in the horizontal plane, thereby driving the upper rotating shaft 4 to rotate in the horizontal plane. Due to the cooperation between the rectangular column 10 and the rectangular cavity in the upper rotating shaft 4, the upper rotating shaft 4 drives the rectangular column 10 to rotate, and the rectangular column 10 drives the lower rotating shaft 9 and the crushing head 15 to rotate. In this way, the crushing head 15 descends while rotating. When the crushing head 15 contacts the soil, the hard soil can be crushed. After the hard soil at multiple positions is crushed, the shovel body 1 is used to dig the soil. This is convenient for the staff to dig the hard soil. In the operation process, only the pressing plate 6 needs to be pressed to crush the hard soil, and the operation is convenient and simple.
[0028] When used specifically, when the soil in the excavated area is relatively hard, this device can be selected, and when the soil is relatively soft, a conventional shovel can be selected.
[0029] The limiting mechanism in this embodiment is a limiting bolt, which can pass through the handle 2 and enter the pressing plate 6, and the limiting bolt is threadedly connected to the handle 2 and the pressing plate 6. The limiting mechanism in this embodiment can also adopt a matching buckle, etc., as long as the handle 2 can be fixed.
[0030] In this embodiment, the top wall and the bottom wall of the receiving box 3 are both provided with a first through hole, a first bearing is arranged in the first through hole, and the upper rotating shaft 4 is connected to the inner wall of the first bearing, so that the upper rotating shaft 4 and the receiving box 3 are rotatably connected.
[0031] In this embodiment, a second through hole is opened on the bottom plate 8, a second bearing is installed in the second through hole, and the lower rotating shaft 9 is connected to the inner wall of the second bearing, so that the lower rotating shaft 9 and the bottom plate 8 are rotatably connected.
[0032] In this embodiment, the sliding column 7 and the rack 5 are respectively arranged on the left and right sides of the handle 2. When the pressing plate 6 is pressed, the movement is more stable.
[0033] The crushing head in this embodiment is made of metal material, and the remaining parts are made of lighter plastic to reduce the overall weight and set the size of each component as small as possible.
[0034] The bottom of the crushing head 15 in this embodiment is sharp. In this embodiment, the bottom of the crushing head 15 is sharp, which is convenient for the crushing head 15 to enter the soil for crushing.
[0035] In this embodiment, there is a gap between the upper rotating shaft 4 and the front wall of the handle 2. When the crushing head 15 is not used to crush the soil, it is convenient for the user's hand to pass through the gap to hold the handle 2 for normal use.
[0036] In order to better apply force to the pressing plate 6, the pressing plate 6 in this embodiment is configured to be in an ergonomic shape, and may also be configured to be in a handle shape, etc., to facilitate the hand to apply downward pressure.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
