The square hollow cylinder structure of the positioning sleeve 81 has the cross section shape of the through hole matched with the cross section shape of the bottom beam 3, so that the positioning sleeve 81 is sleeved on the bottom beam 3 and can horizontally move along the length direction of the bottom beam 3. The plow shovel 82 is arrow-shaped, the front end is sharp and has small thickness, the rear end is flat and has large thickness, the arrow shape of the plow shovel 82 can reduce the resistance to soil penetration, and the plow shovel is firm and durable. The rear end of the plow blade 82 is fixed on the positioning sleeve 81 through a bolt, so that the plow blade 82 is obliquely arranged.

The locating sleeve 81 is provided with a locking screw 83 on the side opposite to the side where the plough shovel is located, and the bottom beam 3 is provided with a plurality of locking locating grooves 31 which are evenly distributed on the side close to the locking screw 83, as shown in fig. 6. The end part of the locking screw 83 can be embedded into the locking positioning groove 31, and the position of the positioning sleeve 81 on the bottom beam 3 can be adjusted after the locking screw 83 is unscrewed, so that the distance between two adjacent plough shovels 82 is adjusted; tightening the locking nut 83 secures the adjusted locating sleeve 81 to the bottom beam 3.

A separation assembly 7 is fixedly connected between the end parts of the two side plates 2 and is positioned at the rear side of the bottom beam 3, as shown in fig. 2 and 8. The separating assembly 7 comprises a lap bar 71 fixedly connected to the inner wall of the side plate 2, the lap bar 71 being arranged parallel to the bottom beam 3. The top of the lap joint rod 71 is fixedly connected with a plurality of separating rods 72, the separating rods 72 are vertically arranged on the lap joint rod 71 and are uniformly distributed in an oblique cutting manner, the higher ends of the separating rods 72 are close to the bottom beam 3 and are positioned below the top surface of the bottom beam 3, and the lower ends of the separating rods 72 are positioned at the rear outer side of the leveling plate 4, so that the carrots and soil at the roots thereof continuously lifted by the plough shovel 82 naturally fall on the separating rods 72 from the top of the bottom beam 3, and the soil crushing process is completed in the falling and impacting process; meanwhile, the carrots can be separated from the soil and stay at the top of the separating rod 72, then fall to the rear of the harvester along the lower surface of the top of the separating rod 72, and finally fall on the surface of the soil scattered back to the ground, so that the carrots can be picked up conveniently. Preferably, a rubber sleeve (not shown) is fixedly sleeved on the outer portion of the separating rod 72 to reduce mechanical damage caused by collision between carrots falling on the separating rod 72 and the separating rod 72.

The carding assembly 9 positioned below the separating assembly 7 is fixedly arranged at the bottom of the side plate 2. As shown in fig. 9, the comb assembly 9 comprises a fixed beam 91 fixedly attached to the bottom of the side plate 2, a plurality of comb tines 92 fixedly arranged at the bottom of the fixed beam 91.

The combing tines 92 are arc-shaped bar members made of steel bars, evenly distributed at the bottom of the fixed beam 91 and bent toward one side of the plow blade assembly 8.

The soil crushed by the separation component 7 is scattered on the ground surface randomly, and the combing rake teeth 92 can comb the soil in the advancing process, so that the soil is further refined and loosened; meanwhile, as part of the carrots can directly fall down along with the soil and are completely or partially buried by the soil, the combing rake teeth with the bent structures can push the sudden carrots to roll upwards for a certain distance or expose the surface of the soil, and then the carrots can be picked up conveniently. Preferably, the outside of the comb tines 92 is covered with a rubber sleeve (not shown) to avoid mechanical damage to the surface of the carrots caused by the comb tines 92.

The bottom of the side plate 2 is also fixedly provided with a screed 4 located below the outer end of the separator assembly 7. The top of flattening board 4 is fixed in the bottom of curb plate 2 through bolted connection, and at the in-process of advancing, its bottom pushes away the flattening operation of rolling formula to the soil that combs rake teeth 92 and comb for soil surface is level and smooth, and the plant in the later stage of being convenient for is planted. Preferably, the bottom of the screed 4 is provided with a rubber sleeve (not shown) or is entirely made of a flexible rubber plate to avoid mechanical damage to the carrots scattered on the soil surface during the leveling process.

The overflow outlet 41 is provided at the bottom of the leveling plate 4, so that in the process of advancing the leveling soil, the local redundant and accumulated soil can enter the rear of the leveling plate 4 through the overflow outlet 41, thereby ensuring smooth proceeding of the leveling process. Furthermore, the bottommost end of the combing rake teeth 92 is higher than the bottommost end of the plough shovel 82 and lower than the bottommost end of the leveling plate 4, so that the combing depth of the combing rake teeth 92 is not larger than the shoveling depth of the plough shovel 82, and the combing rake teeth 92 are prevented from directly acting on a hard soil layer to cause tooth breakage or deformation; the leveling plate 4 only repairs the convexo-concave of the surface layer of the soil without excessively leveling the underlying soil, preventing the soil from being excessively pressed to both sides of the leveling plate 4.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
