Abstract

The utility model provides a compound mechanism for producing seed band without adhesive, and relates to a mechanical device for producing seed band, and pertains to the field of agricultural machinery. Two layers of fiber on top and bottom surfaces of the seed band are bonded into a whole through adhesion method by the enterprises producing the seed band, the deficiencies of high manufacturing cost and complicated equipment exist and are not beneficial to environmental protection. The utility model comprises a frame (1). A roller body (2) is provided on the frame (1). The roller body (2) is fixedly connected with a shaft (2-3). The shaft (2-3) is connected with the frame (1) by a bearing (3). The roller body (2) comprises a composite roller (2-1) and a support roller (2-2). The composite roller (2-1) and the support roller (2-2) are arranged in parallel. A slot (2-1-1) and a saw tooth (2-1-2) interval provided with the slot (2-1-1) are provided above the roller plane of the composite roller (2-1). The utility model saves the production cost, and is not liable to damage and cracking of the produced seed band, provides such virtues as pollution free, simple structure, easy operation, facilitated environmental protection and facilitated promotion and application.

Description

Plant subband and do not have the glue composite structure

Technical field: the utility model relates to a kind of mechanical device that is used for the seeding band, belongs to the agricultural machinery field.

Background technology: now, the enterprise of seeding band bonds together by the upper and lower two-layer fiber that gluing method will be planted subband, because sticking with glue method also need prepare drying plant in addition, so it exists the drawback of production cost height, equipment complexity, and because glue is difficult for decomposition in soil, so be unfavorable for environmental protection.

The utility model content: the purpose of this utility model is to provide a kind of need not have the glue composite structure with glue, kind subband simple in structure, it comprises frame 1, on frame 1, be provided with roll body 2, be connected with a 2-3 on the roll body 2, axle 2-3 is connected by bearing 3 with frame 1, described roll body 2 comprises composite roll 2-1 and carrying roller 2-2, and composite roll 2-1 and carrying roller 2-2 are set up in parallel, the sawtooth 2-1-2 that the roll surface of composite roll 2-1 is provided with groove 2-1-1 and is provided with at interval with groove 2-1-1.It is fibrolaminar bonding up and down just can to finish kind of subband easily without glue by structure of the present utility model, saved production cost, owing to utilizing sawtooth to make the fibrage up and down of kind of subband produce the vertically staggered power of fiber, it realizes connecting, the staggered area of fiber is extensive, so the kind subband of Zhi Zuoing is difficult for damaged cracking thus, so and owing to do not use glue pollution-free, the utility model is simple in structure, processing ease, be beneficial to environmental protection, benefits and applies.

Description of drawings: Fig. 1 is the utility model structural representation, and Fig. 2 is the A-A cutaway view of Fig. 1.

Embodiment one: present embodiment comprises frame 1, on frame 1, be provided with roll body 2, be connected with a 2-3 on the roll body 2, axle 2-3 is connected by bearing 3 with frame 1, described roll body 2 comprises composite roll 2-1 and carrying roller 2-2, composite roll 2-1 and carrying roller 2-2 are set up in parallel, the sawtooth 2-1-2 that the roll surface of composite roll 2-1 is provided with groove 2-1-1 and is provided with at interval with groove 2-1-1, and the position of described groove 2-1-1 adapts with the position of planting seed on the subband.When using, motor 5 drives carrying roller 2-2 by sprocket wheel 4 and rotates, carrying roller 2-2 frictionally drives composite roll 2-1 and rotates simultaneously, the fibrage up and down of kind of subband is put into along the junction of carrying roller and composite roll, carrying roller and composite roll rotate simultaneously fibrage to be driven and travel forward, at this moment the sawtooth on the carrying roller can push down fibrage cause fiber staggered finish fibrolaminar compound up and down, groove on the composite roll then holds the space of seed in kind of the subband just, and it has avoided seed crushed in two roller operation process.

Embodiment two: what present embodiment and embodiment one were different is, axle 2-3 on the composite roll 2-1 is connected by rolling bearing units 3-1 with frame 1, rolling bearing units 3-1 comprises screw rod 3-1-1, inner core 3-1-2 and housing 3-1-3, described rolling bearing units housing 3-1-3 and frame 1 Joint, screw rod 3-1-1 be arranged on housing 3-1-3 the top and with housing 3-1-3 by being threaded, inner core 3-1-2 be arranged on screw rod 3-1-1 the lower end and with screw rod 3-1-1 Joint, the termination point casing that described inner core 3-1-2 and composite roll 2-1 go up axle 2-3 is connected together.In the present embodiment, can drive inner core 3-1-2 by adjustment screw rod 3-1-1 and do lengthwise movement along frame 1, because axle head 2-3 and the inner core 3-1-2 of composite roll 2-1 socket-connect, do lengthwise movement so can drive composite roll 2-1 simultaneously, because carrying roller 2-2 is not movable with respect to frame in the vertical, so the distance that can adjust composite roll and carrying roller that moves up and down of composite roll 2-1 is the size of chucking power between composite roll and the carrying roller, thereby realization is compound to different-thickness kind subband, the position between kind of subband and the kind subband composite structure can be adjusted simultaneously easily, and compound good kind subband can be taken out easily.
