Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery, specifically relating to a machine for removing and crushing straw from taproot crops. Background Technology

[0002] To conserve water and prevent soil salinization, static mulching can be used for cultivation. This involves covering the ground with mulch and pre-drilling holes in the mulch, where seeds are sown and harvested. Because the mulch inhibits ineffective soil evaporation, it helps conserve water and prevent soil salinization. However, this static mulching method, to avoid damaging the mulch, prevents the return of straw to the field via rotary tillage. Cotton and okra are common cash crops. These crops have taproot systems with vertical taproots and relatively well-developed, thick lateral roots. Their stems are hard and lignified, allowing for straw removal. Currently, planting holes are mainly cleared manually, but this method is time-consuming, labor-intensive, and costly, potentially delaying the sowing of subsequent crops and hindering agricultural efficiency. Utility Model Content

[0003] In order to solve the problems existing in the prior art, this utility model provides a straw removal and crushing machine for taproot crops. Based on the root characteristics of taproot crops, it uses a removal method to process residual straw and roots, thereby improving agricultural efficiency.

[0004] The specific technical solution adopted in this utility model is as follows:

[0005] A straw-pulling and crushing machine for taproot crops includes a frame that is pulled forward by a traction machine. The frame is equipped with a pulling rod harrow wheel, and the pulling rod harrow wheel is equipped with harrows that extend outward in a spoke-like shape. The harrows form a pulling rod gap for clamping the straw. The pulling rod harrow wheel has rotational freedom by means of a drive mechanism. The straw is pulled out from the loosened crop rows by being clamped by the pulling rod gap on the pulling rod harrow wheel.

[0006] The rear side of the puller rake wheel is also equipped with a discharge auger. The discharge auger is suspended at the tail of the frame by a connecting arm and rotates with the frame. The lower side of the discharge auger is equipped with a discharge chute. The discharge auger is placed in the discharge chute and is in clearance fit with the discharge chute. When the straw rotates to the side of the discharge auger as the puller rake wheel rotates, the straw is clamped and captured by the discharge auger and the discharge chute and pulled out from the gap of the puller rake wheel as the discharge auger rotates.

[0007] The conveying end of the unloading auger is equipped with a crushing mechanism. The housing of the crushing mechanism is provided with an inlet that communicates with the unloading trough. A crushing blade shaft is rotatably installed inside the housing of the crushing mechanism. The housing is also provided with an outlet facing the ground.

[0008] The rake rod on the rake wheel is inclined, and the inclination direction of the rake rod is forward of the rotation direction of the rake wheel.

[0009] The aforementioned lever rake wheel is provided in two or more sets on the frame.

[0010] A guide rod is provided on the front side of the puller rake wheel. The guide rod is fixedly connected to the frame and extends from the rear side of the loosening shovel of the loosening component to the puller rake wheel.

[0011] The beneficial effects of the utility model are:

[0012] This invention uses a rotating lever-driven harrow to uproot the straw. The entire process relies on the gaps between the lever-driven harrow to hold the straw in place, eliminating the need to break the ground and avoid damaging the static mulch film. This facilitates subsequent crop cultivation and improves agricultural efficiency. Attached Figure Description

[0015] In the attached diagram, 1 is the frame, 2 is the guide lever, 3 is the connecting arm, 4 is the pull rod rake wheel, 5 is the rake rod, 6 is the pull rod gap, 7 is the unloading auger, 8 is the housing, 81 is the feed inlet, 82 is the discharge outlet, 9 is the unloading trough, and 10 is the crushing blade shaft. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0017] Specific implementation examples Figure 1 and Figure 2 As shown, this utility model is a straw-pulling and crushing machine for taproot crops, including a frame 1 that is pulled forward by a traction machine. The frame 1 is equipped with a pulling rod harrow wheel 4, and the pulling rod harrow wheel 4 is equipped with harrow rods 5 that are suspended outward in a spoke-like shape. The harrow rods 5 form a pulling rod gap 6 for clamping the straw. The pulling rod harrow wheel 4 has rotational freedom by means of a drive mechanism. The straw is pulled out from the loosened crop rows by being clamped by the pulling rod gap 6 on the pulling rod harrow wheel 4.

[0018] In use, this invention utilizes a tractor as a power traction machine, and the power output of the tractor provides power to the drive mechanism mounted on the frame 1, such as... Figure 1 As shown, when the frame 1 moves forward with the tractor, the straw comes into contact with the rake bar 5 of the rake wheel 4. The straw is then inserted into the rake bar gap 6 and pulled out of the soil by the forward movement of the frame 1 and the rotation of the rake wheel 4, thus realizing the removal of residual straw from taproot crops.

[0019] Further, such as Figure 1 and Figure 2 As shown, a discharge auger 7 is also provided on the rear side of the pull rod rake wheel 4. The discharge auger 7 is suspended at the tail of the frame 1 by means of the connecting arm 3 and forms a rotational engagement with the frame 1. A discharge trough 9 is provided on the lower side of the discharge auger 7. The discharge auger 7 is set in the discharge trough 9 and is in a clearance engagement with the discharge trough 9. When the straw rotates to the side of the discharge auger 7 as the pull rod rake wheel 4 rotates, the straw is clamped and captured by the discharge auger 7 and the discharge trough 9 and pulled out from the gap of the pull rod rake wheel 4 as the discharge auger 7 rotates.

[0020] Subsequently, the straw is conveyed by the unloading auger 7 in the unloading chute 9, pushing the straw to one side of the frame 1, so that the straw is moved to the outside of the static mulch film, making it easier for other equipment to collect or crush it.

[0021] Furthermore, the conveying end of the unloading auger 7 is equipped with a crushing mechanism. The housing 8 of the crushing mechanism has an inlet 81 that communicates with the unloading chute. A crushing blade shaft 10 is rotatably mounted inside the housing 8. The housing 8 also has an outlet 82 facing the ground. After being crushed, the straw is discharged into the film gap through the outlet 82, covering the exposed soil in the film gap, reducing water evaporation, further saving water and inhibiting soil salinization.

[0022] The straw is fed into the housing 8 of the crushing mechanism by the unloading auger 7, and crushed by the rotation of the crushing blade shaft 10. The straw is then discharged to the ground through the discharge port 82 facing the ground, which facilitates the return of the straw to the field.

[0023] Furthermore, the rake rod 5 mounted on the lever rake wheel 4 is inclined, with the inclination direction of the rake rod 5 facing forward of the rotation direction of the lever rake wheel 4. The inclined rake rod 5 is as follows: Figure 2 As shown, the straw can easily enter the depth of the pull rod gap 6 along the inclined direction of the rake rod 5, thereby preventing the straw from falling off. The rake rod 5 is suspended and has metal elasticity, which can provide further clamping force for holding the straw.

[0024] Furthermore, in order to improve the efficiency of a single trip, the lever rake wheel 4 is provided with two or more sets on the frame 1.

[0025] Further, such as Figure 2 As shown, a guide rod 2 is provided on the front side of the pull rod rake wheel 4. The guide rod 2 is fixedly connected to the frame 1. The guide rod 2 extends from the rear side of the rear loosening shovel of the loosening component to the pull rod rake wheel 4.

[0026] The guide lever 2 is used to guide the straw to the opening side of the pull bar gap 6 on the pull bar rake wheel 4 after it has been loosened, so that the straw can enter the pull bar gap 6 and be pulled out.
